[Differentiated approach for determination of the patients treatment tactics in focal affection of brain, using stereotaxic methods].

There were analyzed the results of stereotaxic biopsy in 338 patients, using CRW stereotaxic system (Radionics, U.S.A.), performed with the objective for differential diagnosis and treatment conduction in the focal affection of brain (of tumoral and nontumoral etiology). In the recurrent cystic affection of brain there were determined diagnostic informativity and trustworthiness of the cysts stereotaxic aspirationance, the abscesses drainage and the Ommaya reservoir implantation. There was proved the important significance of stereotaxic methods in differential diagnosis and treatment of the brain focal affection.

[Sequelae of a drug block and the potential for pharmacological correction of the neuroeffector effects on the heart in reversible ischemia of varying duration]. / Posledstviia medikamentoznoi blokady i vozmozhnosti farmakologicheskoi korrektsii neiroéffektornykh vliianii na serdtse pri ego obratimoi ishemii razlichnoi dlitel'nosti.

The development of local reversible ischemia of the myocardium is characterized by the stereotyped time course of changes in the heat neuromediator content: predominant increase in the noradrenalin content in the hyperkinetic stage of the disease and fall in its content with concurrent increase in the acetylcholine content in the hypokinetic stage. Cardiac function changes accordingly. Partial blockade of M-cholino- and beta-adrenoreceptors leads to impaired balance of the neuroeffector influences on the heart under irreversible ischemia. The impairment is shown by more material changes in cardiac activity as compared to those induced by concurrent switch-off of the receptors. Pharmacological correction of sympathetic neuroeffector influences by means of myoephedrine increases heart resistance to its reversible ischemic alteration.
