Physico-chemical and toxico-hygienic aspects of using ethylene oxide for the sterilization of articles for medical use. Part 2. Toxicity and risk of ethylene oxide entering the organism by non-inhalation routes.

Results of investigation of toxicity of ethylene oxide (EO) entering the organism by routes other than inhalation (subcutaneous, intramuscular, intraperitoneal, intravenous) have demonstrated that the substance causes intoxication characterized by polytropic effect on many vitally important organs and systems. The changes in most of the indices under study show a phasic character and dose-time dependence. In both the acute and chronic effect, impairment of the state of the nervous system, the liver, kidney, blood and reactivity of the organism come to the foreground.

Elaboration and testing of insecticidal varnish in aerosol containers for the control of synanthropic cockroaches.

A formula for the filling of aerosol containers has been elaborated on the basis of a mixture of hexachlorocyclohexane (HCH) gamma isomer and tetrametrin, in a ratio 3:1 with the addition of furniture varnish NC-62 to produce the film, Khladon 11/12 (5050) served as propellent. The study of the process of crystallization of the insecticides on the surface of the film has shown that the effectiveness of insecticidal varnishes is the higher, the smaller the size of the crystals and the easier they can be removed from the surface of the film. This can be achieved by including tetrametrin along with HCH gamma isomer in the formula.
