[RBC Na(+)-Li+ countertransport and Na(+)-K+ cotransport in patients with essential hypertension].

The correlation analyses were performed in 60 patients with essential hypertension (EHT) and 77 normotensives (NT) between RBC Na(+)-Li(+)-countertransport (SLC), Na(+)-K+ cotransport (SPT) and blood pressure, Quetelet index (QI), serum insulin, blood lipids, uric acid, blood glucose, etc. Results showed: (1) The SLC in EHT patients were higher, while SPT lower than NT group; (2) The difference between EHT and NT group was much prominent in SLC of male, while prominent in SPT of female; (3) There was no sex difference in SLC and SPT, and the SLC was correlated positively with QI3; (4) By multiple variants stepwise regression analysis, the SLC was shown to be associated positively with systolic and diastolic blood pressure; while the SPT inversely with systolic blood pressure. It suggests that SLC and SPT exert an independent effect on blood pressure.
