The role of dopamine in the mechanism of the regulation of the digestive-transport functions of the enterocyte membrane during stress

The L-DOPA and sulpiridinum effects on the enzymatic transporting function of the enterocytes' membrane, were studied in rats under stress. The L-DOPA was shown to hinder the absorption rate of glucose, whereas sulpiridinum was shown to suppress the main enzymes excepting snerase and alkaline phosphatase, to increase the monomeric and hydrolysate glucose transport. The L-DOPA seems to play a modifying role in the regulation and integration of the digestive-transporting function of the enterocytes' membrane in rats under stress.

The development of adaptive body reactions after intensive physical loading]

The dependence between the activity parameters of muscarine antagonists in the prevention of haloperidol catalepsy in rats and those in tests characterizing the interaction of ligands and various subtypes of m-cholinoceptors was studied. It was established by constructing the mathematical dependence that blockade of m1-cholinoceptors increases, while that of m2-cholinoceptors reduces the antiparkinsonian activity of the drugs. The activity of the muscarine antagonist pentiphan in the prevention of haloperidol-induced catalepsy in rats exceeds the activity of such traditional antiparkinsonian drugs as cyclodol and amedin.     

The use of interference currents and iodobromine baths in the therapy of patients with chronic nonobstructive pyelonephritis

30 patients were exposed to interference currents (IC) alone (group 1) versus 34 patients treated with IC plus iodobromine baths (group 2). After IC action on the region of the kidney projection patients of group 1 experienced positive changes in cellular and humoral immunity providing an antiinflammatory effect. In group 2, the improvement was seen in renal and urinary functions, 24-h urinary excretion of oxalates and calcium diminished. Interference current proved beneficial in chronic pyelonephritis patients with latent inflammation. The combined therapy was effective in patients at high risk of lithogenesis.
