Endometrial estrogen and progestin receptors were quantitatively measured in the cytosol (ERc, PRc) and nuclear (ERn, PRn) fractions, the activity of 17 beta-hydroxysteroid dehydrogenase measured in 13 normal women in the late proliferative phase of the cycle (control group), in 33 patients with adenocarcinoma, and in 6 patients with other malignancies of(More)
Five trials involving 71 piglets and young porkers were conducted to test the toxic action of polychlorinated biphenyls (PCB) added to the complete feed mixtures as Delor 103, 105 or 106 (manufactured by Chemko Strázske) administered to the experimental groups. The intake of these biphenyls for 14 or 21 days at rates from 100 to 250 mg per kg of feed had no(More)
The interactions of an antiestrogen (tamoxifen) and a progestin (medroxyprogesterone acetate) on endometrial 17 beta-hydroxysteroid dehydrogenase activities were studied in short-term experiments (four to 96 hours) in normally menstruating women at the follicular phase and were related to simultaneously measured concentrations of cytosol and nuclear(More)
The effects of elevated adrenocortical activity, induced by cold exposure, weaning or starvation, or exogenous adrenocorticotrophin (ACTH) on the concentrations of thyroxine (T4) and triiodothyronine (T3) in blood serum were investigated in 99 sucking piglets and weaners, divided into five experiments. No changes in concentrations of circulating(More)
In five trials with 100 piglets we studied the effects of thyreoglobulin, potassium nitrite and the thyreostatic preparation Carbimazol, which were added to a complete starter in the period from early weaning to the age of four weeks. Changes in the concentrations of thyroxine (T4) and triiodothyronine (T3) in the blood serum of control unmedicated piglets(More)
The response of T-helper and T-suppressor cells to various immunosuppressive regimens was studied in long surviving cadaveric renal allograft recipients. Eight patients were immunosuppressed with Azathioprine and corticosteroids, 12 recipients were treated with a combination of Cyclosporin A, corticosteroids and Azathioprine for 1 year. Both regimens(More)
The frequency of chromosomal aberrations and exchanges of sister chromatids (SCEs) in peripheral lymphocytes was studied in 65 pigs from five large breeding herds. Four groups comprised fattened pigs and the fifth group consisted of sows from a large multiplier breeding herd. During the investigation, the dust from the sites was analyzed for the presence of(More)
