[Use of personal protective equipment by pathologists and legal physicians working with particularly dangerous infectious diseases]. / Primenenie sredstv individual'noi zashchity patologoanatomami i sudebnymi ékspertami pri rabote s osobo opasnymi infektsiami.

The possibility of pneumosuit use constructed in the Institute to protect the pathology department staff at the hospitals for infectious diseases from HIV virus was studied. The suit is a hose-type suit for protection of respiratory organs and skin using the ventilated underhood space and autonomic air supply. Both the detailed description of this suit and its disinfection scheme developed and tested by authors are presented. The comparative physio-hygienic assessment of pneumosuit and standard antiplaque suit demonstrated a number of advantages of the former during 2 hours work at pathology department. The authors recommend the pneumosuit as an equipment for the protection of skin and respiratory organs of pathologists and legal physicians working with particularly dangerous infections.

[Changes in the cellular reactivity of guinea pigs sensitized with Bacillus thuringiensis]. / Izmenenie kletochnoi reaktivnosti u morskikh svinok pri sensibilizatsii Bacillus thuringiensis.

Changes in the cell-mediated responsiveness of the body under the action of different variants of B. thuringiensis have been studied in experiments on guinea pigs. The data thus obtained indicate that the development of sensitization occurs in the animals, which is manifested by the increase of the sensitivity of leukocytes to the specific allergen and by the increase of the phagocytic activity of peritoneal macrophages. The most pronounced changes in the immune responsiveness of guinea pigs have been observed after the parenteral administration of B. thuringiensis var. galleriae.
