[Prognostic evaluation of sleep in patients in a vegetative state].

Coma in the genuine sense is a dreamlike state that lasts not more than 3 weeks, thereafter it progresses to a vegetative stage of consciousness recovery, except when a patient has died or regained conscious wakefulness. Among those who have achieved the vegetative state progress to the following stage of recovery: mal consciousness or completely return to the initial cognitive level. Others remain in a persistent vegetative state.

[Effect of qualitatively varying nutrition on several parameters of aflatoxin B1 metabolism and toxicokinetics].

The influence of qualitatively different nutrition (physiological and that with lysine, methionine, threonine and vitamins A, B, C deficiencies) on certain toxicokinetic parameters of 3H-aflatoxin B1, after single and multiple (every day, during 5 days) intraperitoneal injections of this agent in a dose of 25 micrograms/animal, was studied in two series of experiments on growing male WAG rats with the initial bw 40-50 g. It has been proved that the main parameters of aflatoxin B1 toxicokinetics depend on the injection multiplicity and the nutrition character. It has been established that the qualitative differences in the nutrition character essentially influence the stages of aflatoxin B1 distribution in the body, the sorption and metabolic transformation in the liver, enterohepatic recirculation, the rate and correlation of the main elimination routes.

[Improved sanitary bacteriological control of dairy production].

Investigation of bacterial contamination in curds and sour cream, and experimental studies on survival rate of a number of pathogenic and opportunistic microorganisms in these products have permitted standardization of the products with respect to coliform bacteria. A permissible level has been determined for bacterial contamination of curds and sour cream.
