| Abstract: | 2- and 4-month-old male spontaneously hypertensive rats (SHR) were injected fusaric acid at a dose of 50 mg/kg body weight. Fusaric acid increased diphosphoinositide (DPI) and triphosphoinositide (TPI) levels in erythrocyte membranes of 4-month-old SHR by 41% and 20%, respectively. 32P incorporation into TPI decreased by 24% in 2- and by 20% in 4-month-old SHR. Phosphatidylinositol metabolism remained unchanged. The results also suggest that fusaric acid normalized DPI and TPI metabolism in erythrocyte membranes of SHR. |
