Acute hypoxia was accompanied by increase of pineal level of cyclic nucleotides and administration of adrenoreceptor antagonists attenuated this effect. Pretreatment of animals with adrenoreceptor antagonists did not influence the effect of acute hypobaric hypoxia on pineal cyclic nucleotide content. This suggests involvement of non-adrenergic mechanisms into augmentation of pineal cyclic nucleotide level. Administration of epithalamin caused an increase of pineal cGMP. Administration of epithalamin to rats pretreated with adrenoreceptor antagonists increased pineal cGMP and to a lesser extent cAMP content. The latter suggests that epithalamin effect was not mediated via sympathetic innervation. It is concluded that non-adrenergic innervation and humoral regulatory mechanisms are obviously involved into activation of pineal gland under conditions of acute stress.</p>","PeriodicalId":23535,"journal":{"name":"Voprosy meditsinskoi khimii","volume":"46 1","pages":"28-35"},"PeriodicalIF":0.0,"publicationDate":"2000-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21649681","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}

The increase of fluidity of rat blood lymphocyte membranes was observed at 20 and 40 min exposure of the lymphocyte suspension to EMF. The increase of ANS fluorescence observed after 20 min exposure to EMF suggested a decrease of cell membrane potential. EMF exerted opposite changes of lymphocyte membrane fluidity of healthy volunteers and the effect depended on the initial level of this parameter. Study of SOD isoenzyme spectrum revealed that Cu,Zn-dependent SOD can account for the superoxide dismutase catalytic activity of supernatant and lymphocytes. The EMF exposure for 20 min caused 2-fold increase of SOD activity. The EMF exposure for 40 min caused the further increase of SOD activity but only in lymphocytes. At the same time the EMF exposure did not influence the actual SOD-activity in erythrocytes. However, there was clear anti-R-reagent-sensitive SOD-activity which was not abolished by DDC. The reasons and possible consequences of these changes of feuidity and SOD-activity under EMF effect are discussed.</p>","PeriodicalId":23535,"journal":{"name":"Voprosy meditsinskoi khimii","volume":"46 1","pages":"72-80"},"PeriodicalIF":0.0,"publicationDate":"2000-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21650901","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}
