The results obtained from these studies are considered. It is shown that relation of higher nervous activity and general and brain hemodynamics is determined by efficiency of the activity, its energy provision (intensity), the level of NET and the rate of automated psychic reactions. A conclusion is made that efficiency of the activity is a basic system-forming factor in a relation arising between higher nervous activity, on the one hand, and general and brain hemodynamics, on the other hand. The higher is the efficiency, the lower are power requirements and the level of NET and the higher is the rate of automated psychic reactions: mental working capacity.</p>","PeriodicalId":12337,"journal":{"name":"Fiziologicheskiĭ zhurnal","volume":"38 6","pages":"78-85"},"PeriodicalIF":0.0,"publicationDate":"1992-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12514230","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is stated that three-fold blood-letting in total volume of 6 ml carried out prior to pregnancy causes symptoms of IDA. Over a period of the whole pregnancy the concentration of hemoglobin and the concentration of erythrocytes were lower than in intact pregnant rats. Tissue hypoxia characterized by disturbance of terminal microcirculation, capillary tissue diffusion and oxygen utilization was observed in pregnant rats with anemia model. Dysfunctional shifts in the system lipid peroxidation (LPO)-antioxidant protection (AOP) as noncompensated process of free-radical oxidation of lipids were revealed in parallel. A comparative estimation of results from treatment in groups of animals which were given and not given enterosorbent Uvesorb together with anti-anemic drug Ferrum Lack permitted determining the presence of anti-anemic and antihypoxic effects in both groups, though the latter was more pronounced in animals which were given enterosorbent. Various results were revealed relative to changes in the LPO-AOP system.
