Using Norland-Cameron Bone Mineral Analyzer BMA 178 Type, it has been found that bone mineral content of the radius is considerably less in male heavy smokers aged 61 to 75 and 76 to 90, then in nonsmokers with similar age. Less difference was found within the group of 61 to 75 year old women. Furthermore, also it has been pointed out that the sensitivity(More)
To investigate the harmful effect of smoking three groups of CBA/Ca male mice of different ages were subjected to smoking for different time durations. Body weight changes and acute cold tolerance were measured throughout the experiment. Thyroid hormone levels (T4, T3), TSH and lipid peroxidation products (as malondialdehyde and lipofuscin) were determined(More)
In old CBA/Ca mice the effect of cigarette smoke was compared with that of 2-mercaptoethanol (2-ME) treatment. It could be stated that spontaneous death was more frequent in animals kept in cigarette smoke than in the control animals. Prevalence of hepatocellular carcinoma was higher in animals kept in cigarette smoke than in the controls. After 2-ME(More)
The initial rate (5 s) of Na+-dependent inorganic phosphate (Pi) uptake in brush-border membrane vesicles isolated from rat proximal tubule was decreased in metabolic acidosis, 0.42 +/- 0.02 vs. 0.59 +/- 0.05 nmol/mg protein, in vesicles from control animals. Phosphate, ammonium, and Ca2+ excretions were increased 100, 600, and 56%, respectively. These(More)
Authors studied the effect of prolonged sex hormone deficiency on some parameters of bone metabolism in calcitonin sensitive young male rats. 30 rats were given aminoglutethimid (AG) for 36 days. Part of these animals received plus dehydroepiandrosterone (DEA) treatment. Corticoid deficiency was substituted by cortisone. In addition 22 rats were(More)
