Abstract:
Saururus chinensis is a perennial herb found in the northeastern regions of Asia, including Korea, China, and Japan, and is used in traditional medicine. Studies have identified the four major constituents in Saururus chinensis water extract (LHF618®) as miquelianin (11.75 ± 0.092 mg/g), rutin (1.20 ± 0.008 mg/g), quercitrin (2.38 ± 0.389 mg/g), and quercetin (0.068 ± 0.017 mg/g). Saururus chinensis can improve the symptoms of ovalbumin- or fine dust-induced allergic pulmonary disease by suppressing the effects of WBCs and neutrophils in BALF and IgE in the serum. Saururus chinensis dose-dependently recovered morphological changes such as mucous hyper secretion (from 2.7 ± 0.46 to 0.6 ± 0.65), pulmonary epithelial cell hyperplasia (from 2.4 ± 0.55 to 0.7 ± 0.67), and inflammatory cell infiltration (from 2.3 ± 0.45 to 0.6 ± 0.43), and effectively controlled cDNA levels and protein levels of IL-13. It inhibited NF-κB translocation and COX-2 protein synthesis and suppressed the expression of PGE2. Our results show that Saururus chinensis controlled allergic pulmonary disease via the anti-inflammatory pathways, NF-κB/COX-2 and PGE2. Saururus chinensis may be a promising drug candidate against fine dust-induced allergic pulmonary disease.

Abstract:
Vessel elements in Anemopsis have simple perforation plates and alternate (sometimes scalariform) lateral wall pitting; Anemopsis has tracheids with large, densely placed pits. These conditions are in contrast with tracheary element features of Gymnotheca, Houttuynia, and Saururus, in which perforation plates are scalariform (many with notably slender bars) and with scalariform lateral wall pitting. Porose pit membrane remnants, which cannot be seen with light microscopy, are newly reported in Houttuynia and Saururus. These porose pit membranes underline the primitive nature of vessels in Gymnotheca, Houttuynia, and Saururus. The highly specialized vessels of Anemopsis may relate to entry into seasonally dry habitats, whereas Gymnotheca, Houttuynia, and Saururus may have experienced unbroken occupancy of mesic habitats.

Abstract:
The genus Saururus, belonging to Saururaceae, contains two species, S. cernuus L. and S. chinensis (Lour) Baill. with common utilization in traditional medicine from Asia to North America for the treatment of edema, beriberi, jaundice, leucorrhea, urinary tract infections, hypertension, hepatitis diseases, and tumors. An extensive review of literature was made on traditional uses, phytochemistry, and ethnopharmacology of Saururus using ethno-botanical books, published articles, and electronic databases. The 147 of chemical constituents have been isolated and identified from S. cernuus and S. chinensis, and lignans, flavonoids, alkaloids, anthraquinones, saponins, and phenols are the major constituents. Various pharmacological investigations in many in vitro and in vivo models have revealed the potential of the genus Saururus with anti-inflammatory, antitumor, anti-oxidant, hepatoprotective, antimelanogenic, lipid-lowering, and bone protective activities, supporting the rationale behind numerous of its traditional uses. Due to the noteworthy pharmacological properties, Saururus can be a better option for new drug discovery. Data regarding many aspects of this plant such as toxicology, pharmacokinetics, quality-control measures, and the clinical value of the active compounds is still limited which call for additional studies.

Abstract:
Background The Saururaceae, a very small family of Piperales comprising only six species in four genera, have a relatively scanty fossil record outside of Europe. The phylogenetic relationships of the four genera to each other are resolved, with the type genus Saururus occurring in both eastern North America and East Asia. No extant species occurs in western Eurasia. The most exceptional find so far has been an inflorescence with in-situ pollen, Saururus tuckerae S.Y.Sm. & Stockey from Eocene of North America with strong affinities to extant species of Saururus. Recent dated trees suggest, however, an Eocene or younger crown age for the family. Methods Dispersed fossil pollen grains from the Campanian (82–81 Ma) of North America are compared to dispersed pollen grains from the Eocene strata containing S. tuckerae, the Miocene of Europe, and extant members of the family using combined LM and SEM imaging. Results The unambiguous fossil record of the Saururaceae is pushed back into the Campanian (82–81 Ma). Comparison with re-investigated pollen from the Eocene of North America, the Miocene of Europe, and modern species of the family shows that pollen morphology in Saururaceae is highly conservative, and remained largely unchanged for the last 80 million years. Discussion Campanian pollen of Saururaceae precludes young (Eocene or younger) estimates for the Saururaceae root and crown age, but is in-line with maximum age scenarios. Saururus-type pollen appear to represent the primitive pollen morphology of the family. Often overlooked because of its small size, dispersed Saururaceae pollen may provide a unique opportunity to map the geographic history of a small but old group of Piperales, and should be searched for in Paleogene and Cretaceous sediment samples.

Abstract:
Stern and rhizome anatomy is reported for Anemopsis californica Hook., Houttuynia cordata Thunb., and Saururus cernuus L. Secondary growth is reported for the first time in Saururaceae. Cambia function indefinitely in Anemopsis in both fascicular and interfascicular areas. Interfascicular cambium is minimal in Saururus and absent in Houttuynia; fascicular cambium is present in both genera and produces a finite quantity of vessels, fiber-tracheids, and axial parenchyma but no rays. Anemopsis has vessels with simple perforation plates plus tracheids in wood, suggestive of adaptation to fluctuating water availability. The scalariform perforation plates of Houttuynia and Saururus suggest an unbroken history of occupancy of mesic habitats. Ethereal oil cells are reported for rays of Anemopsis, and for pith and cortex of the three genera studied. Stern idioblasts and other histologieal details are ineluded along with wood data in anatomical deseriptions of sterns. DNA data as weIl as maeromorphologie al data implicate Saururaeeae, along with Aristolochiaceae, Lactoridaceae, and Piperaceae as paleoherbs elose to the origin of monoeotyledons. Key wood features that unite these families are cited. Chloranthaeeae, whieh share stern endodermis and sealariform perforation plates with Saururaeeae, are also considered elose. Features of Saururaceae that are analyzed with respeet to monoeotyledon origin inelude loss of interfaseieular cambium, minimization of faseieular cambium, lack of imperforate traeheary elements in monocotyledon bundles, trimery, the sympodial habit, and production of adventitious roots.

?Oligoplites palometa (Cuvier) and Oligoplites saurus (Bloch & Schneider) (Osteichthyes: Carangidae) are coastal pelagic fish species. The objective of this study was to investigate the effect of parasitism by isopods and the reproductive biology of the leather jack, Oligoplites spp. A total of 113 individuals of Oligoplites spp (35 of O. saurus and 78 of O. palometa) were captured during the period between January, 2005 and July, 2007 from the coastal waters of Natal, RN. The morphometric and meristic characters were registered; macroscopic analyses were done to collect the isopod parasites and the gonads were observed to verify the reproductive aspects. The crustacean isopod parasite, Cymothoa spinipalpa (Isopoda: Cymothidae) was encountered on the tongue in the oral cavity in both fish hosts. The parasitic indices of C. spinipalpa showed high values of prevalance of 51,4% for O. saurus and 64,1% for O. palometa. The host presented significant correlations between body mass and body length of O. palometa and the number of parasites. Body lengths of female C. spinipalpa were small due to the limited space available in the oral cavity of the host. There was a significant difference in the sex ratio of O. palometa, males outnumbered the females. The isopod parasites showed specificity to the oral cavity of hosts. Macroscopic analyses of gonads showed four stages of gonadal development for both sex of O. palometa: immature, maturing, mature and spent

The present study investigated the reproductive dynamics and parasitism of four species of marine fishes: serra Spanish mackerel, Scomberomorus brasiliensis, Atlantic leatherjacks, Oligoplites saurus and O. palometa,, and Atlantic bumper, C. chrysurus, during the period of August, 2005 to July, 2007, in the coastal waters of Southwest Atlantic Ocean, Brazil. The collected fish samples were measured, weighed, dissected, the gonads were weighed and examined to separate the sex. The gonadosomatic index (GSI), fecundity, type of spawning, the breeding season, the macro and microscopic characterization of the gonads were determined. The ectoparasites from the branchial chambers and bucal cavity of the fish were collected, measured, weighed and identified. The sex ratio of the study fish species were approximately 1M:1F, however, there was a predominance of males of O. palometa (3M:2F). The GSI of fishes varied according to their reproductive cycle and the stage of gonadal maturation. The highest values of GSI and the spawning period coincided with the rainy period of the region. The females presented total spawning and the fecundity was positively correlated with the weight of the ovary and the body. Four stages of development of the gonads immature, maturing, mature and spent were identified macroscopically and histological analyses of ovaries revealed the different phases of oocyte development. Three species of isopod parasites were identified in the study fishes: Livoneca redmmanni, Rocinela signata and Cimothoa spinipalpa. The first two species occurred in the branchial cavities of C. chrysurus and S. brasiliensis. The isopod C.spinipalpa (a new species) was registered for the first time in the bucal cavity of O. saurus and O. palometa. The parasitic isopods preferred the branchial chambers and the bucal cavity of the host fishes as these were protected microhabitats. The isopods parasitized the immature, maturing and mature fishes. The prevalence of infection of isopods in the hosts varied from 16 to 21%, though in O. palometa it was 60%. In the rainy period the highest isopod parasitic occurrence was registered, however, this did not prejudice the normal reproductive cycle of the host fish.
O presente trabalho investigou a din?mica reprodutiva e parasit?ria de quatro esp?cies de peixes marinhos: serra, Scomberomorus brasiliensis, tibiros, Oligoplites saurus e O. palometa e palombeta, Chloroscombrus chrysurus, durante os messes de agosto de 2005 a julho de 2007, nas ?guas costeiras do Sudoeste do Oceano Atl?ntico, Brasil. Os peixes foram medidos, pesados, dissecados, as g?nadas pesadas e examinadas para separa??o do sexo. Foram avaliados o ?ndice gonadossom?tica (IGS), fecundidade, tipo e ?poca de desova e a caracteriza??o macro e microsc?pica do desenvolvimento das g?nadas dos peixes. Os ectoparasitos da c?mara branquial e cavidade bucal dos peixes foram coletados, medidos, pesados e identificados. A propor??o sexual dos peixes estudados foram aproximadamente 1M:1F, enquanto ocorreu um predom?nio de machos de O. palometa (3:2). Os peixes apresentaram IGS variando de acordo com seu ciclo reprodutivo e seu est?dio de matura??o gonadal. Os maiores valores de IGS e a ?poca reprodutiva coincidiram com per?odo das chuvas da regi?o. As f?meas apresentaram desova total e fecundidade com correla??o positiva para o peso das g?nadas e do corpo. Quatro est?dios de desenvolvimento das g?nadas foram identificados macroscopicamente: imaturo, em matura??o, maduros e esgotados, e os estudos microsc?picos mostraram o desenvolvimento ovocit?rio dentro de cada est?dio. Tr?s esp?cies de parasitos isopodos foram identificadas nas quatro esp?cies de peixes: Livoneca redmmanni, Rocinela signata e Cimothoa spinipalpa. As primeiras duas esp?cies ocorreram na cavidade branquial de C. chrysurus e S. brasiliensis. Parasitismo por isopodo C.spinipalpa, (uma esp?cie nova) foi registrado na cavidade bucal de O. saurus e O. palometa. O micro-h?bitat preferido pelos parasitos is?podos foram ? c?mara branquial e a cavidade bucal do hospedeiro, ?reas mais protegidas. Os isopodos parasitaram os peixes nos est?dios imaturo, em matura??o e maduros. A preval?ncia de infec??o de isopodos nos hospedeiros variou de 16 a 21%, enquanto que em O. palometa foi de 60%. No per?odo das chuvas foi registrada a maior ocorr?ncia de parasitismo por isopodos, porem, o parasitismo n?o prejudicou o ciclo reprodutivo normal dos hospedeiros.

"Saururus cemum—Indigenous American names include ishuna ignone (Choctaw), oyihilíswa (Creek), and yahkakayíkcí (Mikasuki). The Seminole names mean “widow or widower medicine” because it is used to help the bereaved get over their loss. (See p. 608.) Stachys floridana—“Florida betony,” like other perennial species in Stachys, has edible tubers.
