Texto completoSterility is mandatory requirement for most biomaterials. Because of their known sensitivity, hydrogel sterilization poses as a challenge, particularly when it comes to nanostructures or when drugs are incorporated. The main goal of this work was to study the key effects of different sterilization methods on the properties of different types of hydrogel-based systems. In addition to the conventional methods (steam heat and gamma radiation) the applicability of a promising new ozone method was assessed. Two formulations of synthetic hydrogels for ophthalmic applications (representing conventional contact lenses and new generation silicone-hydrogel contact lens), unloaded and loaded with ophthalmic drugs, were studied; and a natural chitosan-based nanostructured hydrogel (nanogel), with a broad spectrum of possible applications. Changes in the essential properties were evaluated. For synthetic hydrogels: swelling, optical properties, ionic permeability, wettability, morphology and topography, chemical structure, mechanical properties, cytotoxicity and drug release profile. For the nanogel: average particle size, zeta potential, polydispersity index, absorbance, morphology, chemical structure and cytotoxicity. In order to ensure the effectiveness of the sterilization methods, sterility tests were carried out after purposely contaminating the samples with different loads of biological indicators. Seam heat sterilization proved to be the most aggressive method for the nanogel, while being the least aggressive for the synthetic hydrogels in the presence and absence of drugs. Regarding gamma irradiation, the nanogel resistance to irradiation increased considerably in the presence of protective sugars. The synthetic hydrogels were resistant to this technique, showing signs of severe degradation only at the highest dose (25 kGy). In the presence of drugs, gamma irradiation proved to be inadequate due to drug degradation. The obtained results were encouraging with regard to the applicability of ozone sterilization for both the nanogel and the unloaded synthetic hydrogels. The drugs generally undergo degradation when exposed to this oxidizing agent. In view of the evident complexity of the factors involved (e.g. nature, composition and properties of materials, drug stability, conditions and parameters of sterilization processes), it is difficult to generalize the effects and predict the outcome of the sterilization methods. The selection of the most suitable procedure must be made on a case-by-case basis.

Texto completoIn 1967, a letter sent to the British Medical Journal reported that the re-sterilization with Ethylene Oxide (EtO) of previously irradiated Polyvinyl Chloride (PVC) formed large amounts of ethylene chlorohydrin, a highly toxic compound. Even though it did not present measured data, this letter initiated a controversy that still divide the opinion of researchers to date. To solve this doubt is relevant, as PVC products submitted to gamma radiation are usually re-sterilized with EtO, when the sterilization validity has expired, which is determined by the manufacturer. The present study aimed at assessing the toxicity of PVC tubes through the cytotoxicity test, using the NCTC clone 929 cell culture agar diffusion test. Four experimental groups were created with 81 analysis units: G1, consisting of tubes in natura; G2, consisting of tubes submitted to gamma radiation; G3, consisting of tubes submitted to EtO sterilization and G4, consisting of tubes submitted to gamma-radiation and re-sterilized with EtO. The tests were carried out in triplicate and each tube was tested in order to represent its internal and external surfaces, as well as its mass. After the measurement of the colorless halo, the analysis units were graded according to the degrees of biological reactivity described in the ISO 10993-5:2009. Only the analysis units that were considered grade 3 and above were considered cytotoxic. The results showed evidence of cell toxicity only in G3, which disclosed plaques that presented death of all cells, a fact that necessitated repetition of the experiment, according to the adopted methodology. The first repetition showed the persistence of the analysis units to cause the death of all cells in the plaque. At the second repetition, none of the analysis units was classified as being cytotoxic. It was inferred that there were failures in the process of aeration in group G3 and in the first repetition. The results of the gas chromatography of groups G3 and G4 demonstrated that the materials from both groups would be safe for use. The maximum value of residues found in both groups was identical, in disagreement with the cytotoxicity test results. It was concluded that, according to the conditions of this experiment, the PVC materials submitted to gamma-radiation and consecutively sterilized by EtO are not cytotoxic and that the gas chromatography, when used alone, can yield debatable results regarding the safety of materials sterilized with EtO.

AECL deposited and Nordion deposits radioactive waste material at their Chalk River disposal site. For transport from the supplier to the user (and back to the supplier when most of the source strength is exhausted) ^C o and I37Cs are shipped in special steel casks. These are designed to survive severe traffic accidents, fire, or other disasters. In order to minimize corrosion of cobalt pins or cesium capsules in the irradiation facility, the water of the source storage pool is constantly recirculated through a deionizer. A sensitive radiation monitor close to the deionizer is used to detect any radioactivity in case the water should be contaminated by a leak in the source. Nordion estimated in 1991 that 17 MCi of 60Co was in service worldwide, installed in 170 irradiators in 45 countries. Many of these facilities have been in operation for more than 20 years. They are mostly used for radiation sterilization of medical disposables, and only in some countries are they also used for irradiation of foodstuffs. Details on the design of various types of gamma irradiation facilities can be found in a number of review articles and book chapters ( -). Some of the earliest systematic studies on food irradiation were carried out with x-ray machines. X-rays are produced when matter is bombarded by electrons of sufficiently high kinetic energy. An x-ray tube (Fig. 5) consists basically of an evacuated glass bulb containing a wire filament which can be heated and opposite it a piece of metal, usually tungsten, which can be cooled. The filament is given a negative charge (cathode) and the metal a positive charge (anode, or anticathode). When the cathode filament is heated by passing an electric current through it, it emits electrons. When these hit the anode, x-rays are produced. The anode must be cooled because in a typical x-ray tube about 99% of the energy carried by the electrons may be converted to heat, and only about % appears in the form of".
