[Osteoarthrosis of the knee joints in climacteric women with excessive body weight or obesity].

The purpose of the study was to evaluate body weight (BW) effect on the frequency and clinical manifestations of knee joint osteoarthrosis (KJOA) in climacteric women with excessive BW or obesity. The subjects of this case control study were divided into three groups: group 1 consisted of 283 climacteric women with normal BW; group 2 consisted of 283 women with excessive BW; 283 obese women constituted group 3. All the three groups were comparable by age and menopause duration.

[Radiation reactions and the possibilities for their modification in rats exposed in the area of the Chernobyl Atomic Electric Power Station].

A study was made of some embryological, hematological, cytogenetic and biochemical characteristics in Wistar rats exposed within the Chernobyl NPP zone over a period of 30 days (the average radiation background level, 75, and at the soil surface, 115 mR/h; a cumulative dose, 57 rad/30 days, and for pregnant rats, 36 rad/20 days). The quantity of chromosome aberrations in bone marrow metaphases and the embryonal death rate were invariable; some cases of teratogenesis were, however, observed. The total number of karyocytes in the brain and the leukocyte content in the peripheral blood sometimes decreased.
