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.

The significance of gastric helicobacteriosis in the genesis hemorrhage from duodenal peptic ulcer

Based on a comprehensive analysis of findings from examination and surgical treatment of 196 patients with bleeding pyloroduodenal ulcers, it was found out that patients with concurrent helicobacteriosis of the stomach are prone to more unfavourable course of their illness, which fact is evidenced by a greater loss of blood and higher risk for bleeding recurrences. A classification is proposed by the authors, taking advantage of the data from endoscopic, microscopic and immunoenzymatic techniques, with the purpose of providing an assessment of degree of severity of helicobacteriosis of the stomach.     

Passive care and active rehabilitation in a patient with failed back surgery syndrome

Blood-borne cytokines enter the brain by transport across the blood-brain barrier (BBB) or by leakage through extracellular pathways at sites, such as circumventricular organs (CVOs), without a BBB. We used radioactively labeled albumin (T-Alb) to differentiate the relative contribution of transport and extracellular pathways to the passage of interleukin-1 alpha ([125I]IL-1 alpha) across the BBB. The major mechanism of entry for [125I]IL-1 alpha after intravenous (i.v.) injection was a saturable transport system with extracellular pathways accounting for only a small fraction of entry into brain. CVOs concentrated blood-borne [125I]IL-1 alpha in a saturable manner to a much greater extent than did the cerebral cortex and cerebellum, but accounted for less that 5% of total brain uptake. After intracerebroventricular (i.c.v.) injection, [125I]IL-1 alpha and T-Alb were concentrated in the CVOs, especially the median eminence, although CVOs contained less that 1% of the substances injected. Distribution after i.c.v. injection was largely due to diffusion and leakage through extracellular pathways. We conclude that after i.c.v. injection, leakage across extracellular pathways accounts for the small but concentrated amount of [125I]IL-1 alpha found in CVOs. After i.v. injection, transport across the BBB accounts for the majority of [125I]IL-1 alpha in brain.
