Abstract:
A new method of rabbit control has been developed using carbon monoxide generated by ignition of a cartridge containing sodium nitrate, charcoal and zinc oxide. Ignition of cartridges inside the entrances of an unoccupied artificial rabbit warren showed that carbon monoxide dispersed poorly through the warren and diffused out of the warren within 3–4 hours. Wind speed and direction markedly affected the distribution and persistence of carbon monoxide. Nevertheless, concentrations of carbon monoxide within most of the warren were sufficiently high to render rabbits rapidly insensible, but in some deeper parts of the warren, they remained at low levels, unlikely to have any effect on rabbits. Field trials showed that treatment of rabbit warrens with carbon monoxide cartridges (79 ± 10.8% kill) was as effective as treatment with cyanide powder (78 ± 11.9% kill), and suggested that rabbits were quickly rendered insensible. Therefore the technique shows considerable promise as an effective, safe and relatively humane method of rabbit control.

Abstract:
The effect of rabbit control methods on rabbit populations and subsequent changes in vegetation were assessed over 2 years on a calcareous shrubby grassland in central Australia. Warren ripping and fumigating decreased mean population levels to four rabbits per kilometre of spotlight transect, and 1080 poisoning decreased mean levels to 9 km-1, compared to the untreated levels of 20 km-l. Release of European rabbit fleas did not have any significant effect on rabbit populations. In the untreated rabbit populations, 68% of the fluctuation in numbers was accounted for by total rainfalls in the previous summer and the previous winter, and by a forage greenness rating. Experimental control of rabbits combined with exclosures indicated that grazing by high numbers of rabbits reduced the frequency of Enneapogon spp. at one site whereas levels rose in all other sites during the two years of good rainfall. The frequency of several species, such as Chenopodium cristatum, Phyllanthus rhytidospermus and Portulaca oleracea, was highly correlated with rabbit density in the previous year, suggesting that rabbit grazing promotes their increase. Grazing'by rabbits alone depressed standing biomass in the following season by 300 kg ha-1 from a maximum 1200 kg ha-1 within the exclosures. Cattle grazing further decreased biomass by 150 kg ha-1. Seedlings of Acacia kempeana were almost absent in those areas open to rabbit grazing, but they were reasonably dense where rabbits were excluded. However, the vegetation response over the 2 years of experiment was due mainly to seasonal changes rather than rabbit control, and does not justify the expense of rabbit control at this stage. Substantial improvement in vegetation composition over the longer term may alter this conclusion.

Abstract:
The acceptability of four different bait station designs (drum, slab, tyre, corrugated iron) to rabbits was tested in the field using unpoisoned oat bait. The drum (200 L, cut longitudinally) and the raised concrete slab (60 × 60 cm) designs were the most acceptable to rabbits. The raised tyre design was unacceptable, and this was supported by later field efficacy trials that compared the drum and tyre designs using 1080 One-shot oats. The efficacy of three of these designs (drum, slab, tyre) against ‘urban’ rabbits was assessed more fully using pindone oat bait. The tyre stations were again found to have little impact on rabbit numbers. With the exception of one drum site where pindone bait stations were totally ineffective, the proportional reductions in rabbit numbers for the remaining sites were similar between the drum (69%, n = 3) and slab (70%, n = 5) designs. However, the slab design provided much easier access to bait by non-target species (particularly birds), and we therefore recommend that the drum design would be the best bait station for controlling rabbits. The overall proportional reduction in rabbit numbers achieved with pindone bait stations was 48% (range 0–80%, n = 13), which is less than that usually achieved during broadacre control programs with pindone (60–90+%). In addition, these kills took 30–60 days to achieve, and as rabbit damage still occurred over this period, the use of pindone bait stations did not always result in damage mitigation or, ultimately, an economic benefit. Some potential problems associated with the use of pindone bait stations, such as the possibility of the development of ‘resistance’ to pindone bait and the risk to non-target species, are also discussed. The combined use of track counts and a ‘digs’ index proved a reliable indicator of changes in rabbit abundance.

Abstract:
ABSTRACT The viral biocontrol agents Myxoma virus (MYXV) and Rabbit Haemorrhagic Disease Virus (RHDV1), released in 1950 and 1996 respectively, are the only control tools to have resulted in significant and lasting landscape-scale suppression of rabbit populations in Australia. Multiple conservation benefits and significant economic savings have resulted from the long-term and widespread reductions in rabbit numbers and impacts. In an effort to ‘boost’ rabbit biocontrol, an additional variant of RHDV1 ('K5') was recently released nationwide to counteract the decreasing effectiveness of both RHDV1 and MYXV that results from the evolutionary ‘arms race’ between viruses and their hosts. Two years prior to the K5 release, an exotic RHDV strain (RHDV2) appeared in Australia. The commercially available vaccine used to protect pet and farmed rabbits against the officially released K5 was ineffective against the exotic RHDV2, resulting in numerous deaths of domestic rabbits. This created substantial confusion about which strain was released as a biocontrol tool, as well as renewed concerns amongst pet rabbit owners and rabbit farmers about the use of viruses as lethal rabbit control tools in general. Ongoing effective control of wild rabbits in Australia is absolutely essential to protect the substantial conservation gains made by the long-term suppression of rabbit numbers over the past decades, and there is currently no alternative population control tool to achieve this at the required landscape scale. Vaccine formulations need updating to protect non-target farmed and pet rabbits from circulating field variants, including RHDV2, and to increase public acceptance for the ongoing use of viral biocontrol for feral rabbit populations.

Abstract:
Context For over 100 years, control efforts have been unable to stop rabbits causing damage to cattle production and native plants and animals on large properties in arid parts of Australia. Warren destruction by ripping has shown promise, but doubts about long-term success and the perceived expense of treating vast areas have led to this technique not being commonly used. Aims This study measured the long-term reduction in rabbit activity and calculated the potential cost saving associated with treating just the areas where rabbits are believed to survive drought. We also considered whether ripping should be used in a full-scale rabbit control program on a property where rabbits have been exceptionally resilient to the influence of biological and other control measures. Methods Rabbits were counted along spotlight transects before warrens were ripped and during the two years after ripping, in treated and untreated plots. Rabbit activity was recorded to determine the immediate and long-term impact of ripping, up to seven years after treatment. The costs of ripping warrens within different distances from drought refuge areas were calculated. Key results Destroying rabbit warrens by ripping caused an immediate reduction in rabbit activity and there were still 98% fewer rabbits counted by spotlight in ripped plots five months after ripping. Seven years after ripping no active warrens were found in ripped plots, whereas 57% of warrens in unripped plots showed signs of rabbit activity. The cost of ripping only the areas where rabbits were likely to seek refuge from drought was calculated to be less than 4% of the cost of ripping all warrens on the property. Conclusions Destroying rabbit warrens by ripping is a very effective way of reducing rabbit numbers on large properties in arid Australia. Ripping should commence in areas used by rabbits to survive drought. It is possible that no further ripping will be required. Implications Strategic destruction of warrens in drought refuge areas could provide an alternative to biological control for managing rabbits on large properties in the Australian arid zone.

Abstract:
Rabbits have caused enormous damage to the vegetation on seven islands in the sub-Antarctic Kerguelen archipelago, including the main island, Grande Terre. Rabbit sera collected during 2001–02 were tested for antibodies against myxoma virus and rabbit haemorrhagic disease virus with a view to considering the wider use of these viruses to control rabbits. The results confirmed work done 15–20 years earlier that suggested that myxoma virus has not spread across all parts of Grande Terre and occurs at low prevalence among rabbits. By contrast, on Ile du Cimetière, where European rabbit fleas were introduced in 1987–88, the prevalence of myxoma antibodies is high and the rabbit population is relatively low, supporting the idea that the fleas are effective vectors of myxoma virus. Consequently, there should be benefits in releasing fleas on Grand Terre to enhance disease transmission. Reactivity of some rabbit sera in RHD-specific ELISAs suggested that a virus similar to RHDV may be present at low prevalence on Grande Terre but most rabbits are likely to be susceptible and this virus could be considered for use as a future biological control agent.

Abstract:
Blood parameters are an important index to assess the body homeostasis in mammals. Here, the effect of pesticide (imidacloprid) contaminated feed exposure on the haematological parameters of adult rabbits (n=15) was studied. Pesticides (Imidacloprid, Bildor® 0.5ml (100mg)/L water spray on vegetables and green grass) exposed feed fed to rabbits with wash (washed feed rabbit) or without a wash (not washed feed rabbit) in the once-daily morning for every alternative day up to 15 days. Control rabbits have received a standard diet (fresh vegetables and green grass). The blood cell analysis showed that the total erythrocyte count, packed cell volume, and haemoglobin values were not changed significantly in pesticide exposed rabbit. For differential leukocyte count, the percentage of neutrophil and eosinophil was significantly decreased in the pesticide-exposed rabbit as compared to the control rabbit. The lymphocyte percentage was increased significantly in pesticide-exposed rabbits compared to control rabbits. Interestingly, the number of lymphocytes was significantly increased in not washed feed rabbits compared to wash feed rabbits. The results of the present study suggest that residue of agriculturally used pesticides may affect the body homeostasis of animals. Res. Agric., Livest. Fish.7(3): 439-444, December 2020

Abstract:
The metabolism of plasminogen glycoforms I and II was measured in alloxan-induced diabetic and in age-matched control rabbits. Radiolabeled plasminogen I and II were degraded significantly more slowly in diabetic compared with control rabbits; plasminogen II [half-time (T1/2), 1.31 days] was degraded faster than plasminogen I (T1/2), 1.86 days) in diabetic rabbits and in control rabbits (T1/2, 1.18 and 1.58 days, respectively). From the catabolic rates and relative quantities in plasma, we calculated that approximately four molecules of plasminogen II were degraded for one molecule of plasminogen I in the diabetic and control rabbits. To verify this later observation, plasminogen I and II production by diabetic rabbit livers was compared with that by the control livers in vitro. During perfusion with [3H]leucine, 3H-labeled protein was released more slowly from diabetic than from control livers, but no quantitative difference in total plasminogen yield between diabetic and control livers was found. Nevertheless, plasminogen II was produced 0.7 +/- 0.4 and 4.3 +/- 0.3 times faster than plasminogen I by diabetic and control livers, respectively. Plasminogen metabolism in the diabetic rabbit did not differ qualitatively from that in the control rabbit except that catabolism was slowed.

Full text
Abstract:
Serological data from wild rabbits support the hypothesis that a second RHDV-like virus was already present in Australia before rabbit haemorrhagic disease virus (RHDV) was introduced as a biological control agent. This putative virus apparently persists in most wild rabbit populations in the presence of RHDV, and antibodies raised against it appear to protect some rabbits from fatal rabbit haemorrhagic disease (RHD). High titres of these antibodies are most commonly found in rabbits from high rainfall areas; this may explain why the initial mortality from RHD declined as the disease spread from dry areas into wetter regions and why it remains less effective as a biological control in wetter regions today. The implications for further advances in rabbit control are discussed, including the need to isolate this putative RHDV-like virus and develop specific ELISA tests to facilitate its detection in the field.

Abstract:
Context European rabbits have a great impact on native vegetation and small vertebrates in Australia. Rabbits consume vegetation and promote invasive plants and invasive predators, and compete directly and indirectly with native animals suppressing those populations. Aims We explored the changes in small native vertebrates and invertebrates following the removal of rabbits. Methods Warren ripping was undertaken on a property in south-western Queensland at four sites and the results of pitfall trapping were compared with four nearby paired control sites. Invertebrates and small mammals were counted in pitfall traps, and bird surveys were conducted in all treatment and control sites. Key results Following a rabbit-control program, we observed a four-fold increase in the number of dunnarts trapped in treatment plots, whereas no change was observed in control plots. The spring following the rabbit-control program also saw an increase in some lizards in treatment plots. Conclusions The presence of rabbits in arid-zone Australia can suppress native animal populations. Implications Many species of small native mammals and lizards rely on food sources that fluctuate greatly with environmental conditions. The presence of rabbits altering the landscape, supporting introduced predators, reducing vegetation and, therefore, insects, adds increased pressure for insectivorous species. Rabbit control through warren ripping in arid-zone Australia is an effective method to reduce rabbit numbers, and allowed for an increase in small vertebrates in treated areas.

Abstract:
The experiments described in this thesis were designed to assess changes in pasture dynamics (biomass and species composition of pasture) of grazing land on the Southern Tablelands of ACT and NSW, after 16 combinations of rabbit control treatments had been applied. The rabbit control performed by CSIRO Division of Wildlife and Ecology consisted of all combinations of presence-absence of Poisoning (using sodium monofluoroacetate, 1080: POIS), Ripping (ripping warrens using a tractor fitted with ripping tynes: RIP), Fumigation (pressure fumigation using chloropicrin: FUM) and repeated follow-up fumigation (using phostoxin pellets one, six and eighteen months after completion of the initial treatment: ANN). The pasture was assessed before treatments were applied, and every six months after rabbit control treatments. Treatment combinations were assigned randomly in a 24 factorial design on a total of 32 sites. There was a significant increase of pasture biomass at the RIP+ANN treatment at post-treatment sample 5. The analysis of covariance did not detect any other significant increase or decrease of pasture biomass for any rabbit control treatment, at any posttreatment sample. A significant increase of grass species occurred for the treatments of POIS+RIP+FUM, POIS and RIP+ANN for the post-treatment samples of 1, 3 and 5 respectively. There was a significant increase of thistles at the rabbit control treatments of POIS+RIP+FUM+ANN (post-treatment sample 1), RIP, ANN, RIP+FUM, RIP+FUM+ANN and POIS+RIP+FUM+ANN (post-treatment sample 3) and RIP and FUM+ANN (post-treatment sample 5). A significant increase of weeds occurred at FUM (post-treatment sample 3) and at FUM+ANN (post-treatment sample 5). No significant changes in the amount of herbs or legumes was apparent for any rabbit control treatment or post-treatment sample. There were no significant decreases for any species group. Except for the significant results for post-treatment sample 1, all significant increases of biomass for any species group occurred during spring (post-treatment sample 3 and 5) which suggests a growth phase during spring then subsequent dieback (particularly for thistles and weeds), as any change was not detected in the following autumn sample. No strong trend is evident for any particular rabbit control treatments, or any combination of treatments. Analysis of covariance revealed that the rabbit control treatment of RIP+ANN showed significant increases in both total biomass of pasture and grass biomass during post-treatment sample 5. This treatment reduced the number of active entrances the most. Significant positive correlations were found between pasture biomass (total) with grass, herb, legume, thistle and weed species groups. Significant negative correlations between grass biomass and the number of active entrances were found when the rabbit control had been highly effective in reducing the number of active entrances. When rabbit control had not been very successful, there was a significant positive but low correlation with the number of active entrances. There was no significant relationship between the number of active entrances with the weight of rabbit dung pellets. It is reasoned that they are different measures of rabbit abundance. More rabbit dung pellets were found closer to the warren than further away from the warren, but there was no correlation between rabbit dung and pasture biomass. Rainfall was above average for most of the experiment, biomass increased accordingly, and rabbit control was highly successful. The resulting changes in the pasture were difficult to detect, although some increases in species composition groups occurred. It is reasoned that the changes observed are partly attributable to seasonal conditions, and to high rainfall. Grazing by domestic animals, sheep and cattle, had been found to be consistent throughout the experiment.

Abstract:
This thesis investigates aspects of the community ecology of rabbit parasites with particular emphasis upon the gut helminths, utilising a 23 (later extended to 26) year time series of rabbits and their parasites. A clearer understanding of parasite communities can lead to more effective biological control strategies. Rabbits are regarded as a serious pest species throughout Europe and the Antipodes and the use of the myxomatosis virus, as a biological control agent, has already been tried and failed. However, a clearer picture of the parasite community may offer future possibilities for control. Additionally, the rabbit is a good model for other grazing species, as it carries a similar gut helminth community. Drug resistance is an increasing problem in a wide range of parasites. A clearer appreciation of parasite communities could also aid in the search for effective and environmentally sound pathogen control strategies (e.g. via cross immunity or competition with benign species). Theoretical models have revealed the importance of aggregation to the stability of the host parasite relationship, to parasite evolution and to interspecific parasite interactions. A number of models have considered the effect of varying aggregation upon these dynamics with differing outcomes to those where aggregation was a fixed parameter. Here the stability of the distribution for each of the rabbit helminths was examined using Taylor's power law. The analyses revealed that aggregation was not a stable parameter but varied with month, year, host sex, host age, and host myxomatosis status. Evidence for the existence of interspecific parasite interactions in natural systems has been equivocal. Factors influencing parasite intensity were evaluated for the gut helminth. A network of potential interactions between the parasites was revealed. Only month was shown to be of greater influence on the community. Following, from the above analyses, a community model was constructed which incorporated both seasonal forcing and interspecific parasite interactions, with interaction mediated via host immunity. One unexpected emergent property was an interaction between the seasonality and the immune decay rate with slower immune decay resulting in a shift of the immune response out of phase with the species against which it was produced. The model was also used to assess the potential effects of two control strategies, an anticestodal and a single species vaccine. The vaccine had greater effects on the whole community than the anticestodal because of the immune- mediated interactions. The host is also an integral part of the community as the parasite dynamics are linked with that of their host. Therefore an assessment of the parasites' impact upon host condition and fecundity was also undertaken. This revealed a variety of positive and negative associations between the parasites and their host, with potential implications for future host control strategies. This study has shown that ignoring parasite-parasite or parasite-host interactions and interactions of both the host and the parasite with the external environment, could result in a poor description of the community dynamics. Such complexities need to be considered and incorporated into theory if future control strategies for either host or parasites are to be effective.

Abstract:
Genetic analyses of two endangered species of mammals in the Lower Keys of Florida (Lower Keys marsh rabbit, LKMR, Sylvilagus palustris hefneri; silver rice rat, SRR, Oryzomys palustris natator) were performed to evaluate the genetic structure of their populations. Mitochondrial sequence data (control region; 763 base pairs (bp), LKMR; 788 bp, SRR) were used to explore patterns of genetic variation within and among island populations in both species. Analysis of the SRR also included 8 polymorphic nuclear microsatellite loci (9 to 16 alleles). Phylogenetic analyses of mitochondrial sequence data for both species revealed two main lineages corresponding to eastern and western localities, with high levels of genetic structuring (LKMR FST = 0.982, SRR ΦST = 0.916). The two species differed in the level of sequence divergence between eastern and western populations (LKMR, 19 bp; SRR 4 bp). In addition to an overall similar pattern of genetic subdivision, populations of both species possessed low levels of mtDNA variation (haplotypic diversity in the LKMR = 66.1%, SRR = 58.6%). Microsatellite analyses of the SRR revealed subdivision between eastern and western regions. Although less pronounced than the structure observed in mtDNA, the overall pattern was still apparent. Additional examination of divergence between mainland and Lower Keys rice rats revealed a genetic division that indicated a lack of recent gene exchange between the regions (i.e. no shared haplotypes, the presence of private alleles, and distinctive separation in numerous analyses). Although this degree of division does not warrant species designation, the levels and patterns of divergence, both morphological and genetic, do suggest genetic isolation of mainland and island forms. This fact, along with restricted gene flow between the Lower Keys and the Everglades, suggests that the SRR is on an evolutionary trajectory separate from its mainland counterparts and validates its identification as a separate subspecies, Oryzomys palustris natator. Finally, the genetic division between eastern and western populations of the SRR and LKMR suggests that populations of both species in these two regions of the Lower Keys should be treated as separate management units, especially when considering the enhancement of populations via translocations.

El objetivo de esta tesis ha sido estudiar la respuesta directa a la selección por tasa de ovulación en conejo y las respuestas correlacionadas en tamaño de camada y tasas de supervivencia. Los animales pertenecían a una línea de conejos seleccionada por tasa de ovulación durante 10 generaciones. La selección se realizó en base al valor fenotípico de la hembra, que se midió el día 12 de la segunda gestación mediante laparoscopia. Se creó una línea control a partir de la recuperación de aproximadamente 470 embriones de 50 hembras donantes de la generación base. Los embriones fueron vitrificados y almacenados en nitrógeno líquido hasta su transferencia al final del experimento de selección (generación 10 de la línea seleccionada). Se midieron los siguientes caracteres: tamaño de camada (LS), estimada como el número total de gazapos al parto en un máximo de 5 partos; tasa de ovulación (OR), estimada como el número de cuerpos lúteos en los dos ovarios; tasa de ovulación derecha y tasa de ovulación izquierda (ROR y LOR); el número de embriones implantados totales (IE), en el lado derecho (RIE) y en el lado izquierdo (LIE); la diferencia ovulatoria (OD), definida como la diferencia entre ROR y LOR, expresada en valor absoluto; la diferencia de implantación (ID), definida como la diferencia entre RIE y LIE, expresada en valor absoluto; la supervivencia embrionaria (ES), calculada como IE/OR; la supervivencia fetal (FS), calculada como LS/IE; la supervivencia prenatal (PS), calculada como LS/OR. Se utilizó metodología bayesiana para analizar los datos. Las estimas de las heredabilidades de OR, LS, ES, FS y PS fueron 0.16, 0.09, 0.09, 0.24 y 0.14, respectivamente. Las estimas de las correlaciones fenotípicas de OR con LS, ES, FS y PS fueron 0.09, -0.07, -0.26 and -0.28, respectivamente.

La contaminación atmosférica originada por la producción animal intensiva afecta al medio ambiente global, a la salud de las personas y al bienestar de los animales de la propia granja. Se trata de una problemática de creciente interés en países en los que, como en el caso de España, se ha investigado poco hasta el momento. Esta tesis doctoral se centra en la medición experimental de concentraciones y emisiones de gases (amoniaco, metano, óxido nitroso y dióxido de carbono) y partículas (PM10) en granjas de pollos de cebo y de conejos, principalmente en clima mediterráneo, analizando los factores que afectan a dichas emisiones. Para ello, la tesis se compone de cinco trabajos de investigación diferenciados, aunque estrechamente relacionados entre sí. En primer lugar, se estudia en detalle la metodología empleada para medir las emisiones, basado en un balance en el que las variables son la concentración de gases y el flujo de ventilación; por otra parte, se desarrolla un procedimiento para el análisis de la incertidumbre cuyo objetivo es obtener indicadores de la calidad de los resultados. En segundo lugar, se aborda la medición del flujo de ventilación en granjas comerciales mediante el desarrollo de un circuito para la adquisición de información sobre el funcionamiento de los ventiladores. Posteriormente, y en aplicación de los dos anteriores estudios, se determinan las emisiones de gases en dos granjas comerciales de conejos y una de pollos en el litoral mediterráneo español, obteniendo resultados muy útiles para la mejora del inventario nacional de emisiones. Finalmente, se ha cuantificado la influencia de la actividad de los pollos de engorde en las emisiones de partículas y de gases, y se ha evaluado la aplicabilidad de un método para la determinación indirecta de la ventilación basado en el balance de dióxido de carbono. Los resultados obtenidos en estos experimentos y en los correspondientes análisis contribuyen al conocimiento general acerca de las emisiones

Dissertação de Doutoramento em Ciências Veterinárias
A circulação ocular compreende dois compartimentos: o retiniano possui receptores autonómicos e é autoregulado, enquanto que o coroideu possui inervação adrenérgica e existe controvérsia acerca da presença de autoregulação. Nesta tese criámos e optimizámos um modelo experimental de olho isolado de coelho para ajudar a clarificar os mecanismos de controlo locais da circulação ocular independentemente de outras interferências presentes num modelo in vivo. Surpreendentemente, antes da administração de qualquer fármaco, observámos respostas de vasomotricidade intrínseca em todos os modelos experimentais. Validámos o modelo utilizando fármacos adrenérgicos de efeitos conhecidos. A injecção de fenilefrina (α1-adrenérgico) desencadeou uma resposta vasoconstritora e diminuiu a frequência e aumentou a amplitude das oscilações enquanto que a prazozina (α1-bloqueador), a fentolamina (α1,2 -bloqueador) e o labetalol, (αβ-bloqueador) provocaram vasodilatação e diminuíram a intensidade das oscilações de vasomotricidade intrínseca. Analisámos as variações de pressão decorrentes da injecção intraarterial de outros neurotransmissores: a Endotelina-1, o L-NAME (antagonista do Óxido Nítrico) e o Neuropéptido Y induziram uma resposta vasoconstritora e aumento da frequência e amplitude das oscilações enquanto que a L-Arginina (precursor do Óxido Nítrico), o Péptido Vasointestinal e a amlodipina (bloqueador dos canais de cálcio) desencadearam os efeitos opostos. Estes resultados abrem novas perspectivas para a manipulação terapêutica das doenças oculares isquémicas como sejam a retinopatia diabética e o glaucoma
ABSTRACT: Ocular circulation has two compartments: the retina has autonomic receptors and is also autoregulated, while the choroid has adrenergic innervation but there is still some controversy about the presence of autoregulation. In the current investigation we developed an experimental model of isolated rabbit eye to help clarifying the local mechanisms of control of ocular circulation, independently of other interferences present in an “in vivo” model. Surprisingly, before any drug administration, we observed intrinsic vasomotricity in every animal model. We validated the model using adrenergic drugs of known effects. The injection of phenylefrine (α1-adrenergic) elicited vasoconstriction and decreased the frequency but increased the amplitude of the oscillations while prazozin (α1-blocker), phentolamine (α1,2 -blocker) and labetalol, (αβ-blocker) evoked vasodilation and a decrease in both the frequency and amplitude of the oscillations of intrinsic vasomotricity. We analysed the perfusion pressure changes following the intraarterial injection of other neurotransmitters: Endotelin-1, L-NAME (Nitric Oxide antagonist) and Neuropeptide Y elicited vasoconstrition and increased the frequency and amplitude of the oscillations while L-Arginine (Nitric Oxide precursor), Vasointestinal Peptide and amlodipine (calcium channel blocker) evoked the opposite effects. These results open new perspectives to the therapeutical handling of isquemic ocular diseases such as diabetic retinopathy and glaucoma

Abstract:
A one step Enzyme-linked immunosorbent assay (ELISA) incorporating two anti-human FVIII :Ag monoclonal antibodies (MAbs) was used to determine FUIIIrAg in rabbits. Initial examinations showed the presence of cross-reactive FUIII:C in rabbit serum, plasma, and homogenates of normal rabbit liver, lung and spleen. Detailed investigation of normal rabbit plasma, and plasma depleted with Sephacryl S1000-anti FVIII :C MAbs and irrelevant MAbs (as control) using the ELISA, a chromogenic Fl/III:C activity assay, an immunoradiometric assay (IRMA) using human antibody, and fast protein liquid chromatography (FPLC) showed conclusively that the ELISA was specific for FVIII:C. The cross reactive FVIII:Ag was found to be most prominent in rabbit plasma, followed by serum, liver, lung and spleen. The ELISA should enable potential use of the rabbit as an animal model for FVIII:C studies, such as the enhancement of homologous FVIII:C with drugs or following tissue transplantation.
