RESUMEN
Osteoporosis is a chronic disease characterized by a decrease in bone mineral density [BMD] and corruption of the microarchitectural structure of bone tissue. It was investigated whether methylprednisolone had a favorable effect on osteoporotic bone tissue in Oophorectomy induced osteoporotic rats whose endogenous adrenaline levels are suppressed with metyrosine. Bone Mineral Density, number of osteoblast-osteoclast, bone osteocalcin levels and alkaline phosphatase [ALP] measurements were performed. Obtained results were compared with that of alendronate. Oophorectomy induced osteoporosis was exacerbated by methylprednisolone. Alentronate prevented ovariectomised induced osteoporosis, but it couldn't prevent methylprednisolone +ovariectomised induced osteoporosis in rats. Combined treatment with methylprednisolon and metyrosine was the best treatment for preventing osteoporosis but metyrosine alone couldn't prevent osteoporosis in ovariectomised rats

In this study, we investigated the effects of treatment with chronic antihypertensive drugs [clonidine, methyldopa, amlodipine, ramipril and rilmenidine] on oxidant-antioxidant parameters and toxic effects on DNA in rat uterus tissue. In addition, uterus tissues were examined histopathologically. A total of 36 albino Wistar rats were divided into the following six groups: 0.075 mg/kg clonidine group; 100 mg/kg methyldopa group; 2 mg/kg amlodipine group; 2.5 mg/kg ramipril group; 0.5 mg/kg rilmenidine group; and the healthy group. Rats underwent chronic drug administration for 30 days and at the end, biochemical and histopathological examinations were performed. All data were subjected to one-way ANOVA test. We divided these drugs into the following three groups according to their effects on rat uteri: [I] mild negative effects [clonidine], [II] moderate negative effects [rilmenidine, methyldopa] and [III] drugs which had severe negative effects [amlodipine, ramipril]. These data may help with selection of antihypertensive drugs, in order to determine which drugs have the lowest toxicity in pregnant and non-pregnant [pre-pregnancy] women
