Abstract  

Instrumental neutron activation analysis (INAA) and atomic absorption spectrophotometry (AAS) were used to verify the protocols for the quantification of zinc and magnesium in human whole blood. A study was conducted on group of volunteers consisting of 131 patients having cardiovascular diseases (CVD) and 23 malignant hypertension (MH) patients along with 432 control subjects with 218 male and 214 females. The elemental data of these elements has been exploited to establish the base line values in control subjects. The possibility of any relationship between blood Mg and Zn levels with CVD and MH has also been investigated. The mean blood Mg and Zn levels were found to be depleted in both CVD and MH patients as compared to normal subjects. In our findings Mg and Zn were found to have an inverse relation with systolic and diastolic pressure. The reliability of the methods was checked by the concurrent analysis of the IAEA reference material (RM) employing the optimized INAA and AAS protocols. The determined values by both techniques were found to be in good agreement with the IAEA reference values. The elemental data in whole blood samples of normal volunteers has also been compared with Mg and Zn contents reported by other countries.
