Changes of ATP concentration in the plasma, erythrocytes and cerebrospinal fluid of the hypertensive subjects as compared to the control ones have been revealed by means of this method. According to our results ATP concentration significantly increases in the plasma and cerebrospinal fluid and slightly modifies in the erythrocytes of the hypertensive as compared with control subjects. Correlation of data concerning the variation of ATP distribution in the different compartments (plasma, erythrocytes, cerebrospinal fluid) with those related to Na and K content in hypertensive and control subjects seems to be useful for some remarks on the molecular mechanisms in the essential hypertension.</p>","PeriodicalId":77362,"journal":{"name":"Revue roumaine de physiologie (Bucharest, Romania : 1990)","volume":"27 2","pages":"93-7"},"PeriodicalIF":0.0,"publicationDate":"1990-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13243903","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}

Tolbutamid and glibenclamid treatment significantly improves the diabetic taste for glucose, both for detection threshold (DT) (p less than 0.01) and recognition threshold (RT) (p less than 0.001). Also in TTT there is a significant improvement of taste reception: DT falls at 2 h (p less than 0.05), RT falls more slowly at 3 h (p less than 0.05). There is no direct correlation between perception for sweet and glycemia and insulinemia increase in TTT.
