Effectiveness of Protective Activities for Rehabilitation of the Forage Lands in Russia and Belarus Contaminated as a Result of the Chernobyl Accident.

Regularities of changes in the content of (137)Cs in green fodder during the remote period after the CNPP accident depending on application of agro-technical and agrochemical activities are analyzed. It is revealed that the use of mineral fertilizers reduces receipt of (137)Cs from the soil to forage and further to a food chain. It is also established that agrochemical activities are more effective than agro-technical ones.

The blood level of sugar, serum level of cholesterol and triglyceride were not changed in female rats aged between 3 to 14-16 months, whereas insulin and somatomedin levels were increased. In 24-month-old persistent estrous rats the increased insulin, cholesterol and trigliceride levels were found. The oral glucose tolerance test revealed a decrease in glucose utilization, delay of reactive insulinemia and abolishment of an increase in glucose-induced somatomedinemia.

N-nitrosomethylurea (NMU, 20 mg/kg) was administered to rats intraperitoneally on the 21st day of pregnancy. F1 progeny aged 3 months showed a decrease in glucose utilization and in somatomerin content as measured by the glucose tolerance test. The insulin serum level did not differ from control. The cholesterol blood level was higher in the offspring of NMU-treated rats. The ability of diethylstilbestrol to inhibit the compensatory ovarian hypertrophy was decreased in 3-month-old female hemicastrated rats whose mothers had been exposed to NMU. Administration of the antidiabetic drug buformin decreased 3.5-fold the malignant neurogenic tumor incidence in rats transplacentally treated with NMU.

The inhibition of the transplacental blastomogenic effect of nitrosomethylurea by postnatal administration of buformin to rats.

N-Nitrosomethylurea (NMU) (20 mg/kg) was i.p. administered to rats on the 21st day of pregnancy. A decrease of glucose utilisation in the oral glucose tolerance test was found in 3 month old female progeny of NMU-treated rats. The serum insulin level did not differ from control, but serum cholesterol level was higher in offspring of NMU-treated rats. The ability of diethylstilboestrol to inhibit compensatory ovarian hypertrophy was decreased in female hemicastrated 3 month old rats whose mothers were treated with NMU. Postnatal administration of the antidiabetic drug buformin decreased the malignant neurogenic tumor incidence 3.5 times (to rats transplacentally treated with NMU).
