Abstract: | Magnesium, calcium and zinc determinations were performed by flame absorption spectrophotometry and induced coupled plasma on the red blood cells (RBC) and plasma (P) of spontaneously hypertensive (SHR) and control (WKR) male rats, aged of 45 to 158 days. The blood sampling was done by cardiac puncture after ether anaesthesia. SHR rats have lower RBC and P Mg values and higher RBC Zinc values than WKR. These differences are very significant (P less than 0.002 to P less than 0.0001) among the animals aged of 96 days or more. When compared to the data of the literature, these results confirm the existence of associations between hypertension, low blood Mg and high RBC Zn values but reveal only minor changes in RBC Ca concentrations. |
