[Moniside (isosorbide-5-mononitrate)--the effect on some changes in a hyperlipoproteinemia mode in rats]

The influence of the preparation moniside (isosorbide-5-mononitrate on some functional, lipid and enzymic changes in a model of hyperproteinemia of rats was investigated. Studies were carried out on 45 male rats, divided into 3 groups: I group-control, nontreated; II group--control treated with cholesterol diet; III group--experimental treated with cholesterol diet and monoside in a dose of 20 mg/kg of body weight orally 6 days a week. The experiment continued 3 months. Changes in general state, body mass, static physical endurance, stability to electric current were described as well as the following lipid parameters: cholesterol (mmol/l), cholesterol in lipoproteins with high density (LHD), cholesterol in lipoproteins with low and very low density (LLD, LVLD), tryglycerols (Tr), free fatty acids (FFA). Changes in enzymic activity of aspartataminotransferase (ASAT), alaninamidotransferase (AlAt), hydroxybutiratdehydrogenase (HBDH) and creatinphosphokinase (CPK). Morphological examinations of heart, aorta, liver, kidneys and adrenal were made as well. The results from the experiments showed that in a model with hyperlipoproteinemia general state of experimental animals was impaired, body mass was reduced, physical endurance and stability to electric current reduced, while cholesterol and LVLD/were increased, AlAt increased mult many times, but HBDH and CPK diminished their activity. Functional possibilities of the organism increased at a slight degree under the influence of monoside. Lipid changes, established after cholesterol diet, did not change substantially, while deviations in enzymic activity were normalized.
