Macro- and Microelement Status in Animal and Human Hypertension: the Role of the ACE Gene I/D Polymorphism.

Genetic factors that predispose to hypertension may contribute to element disturbances observed in hypertensive patients. We tested the hypothesis that the deletion allele of the angiotensin-converting enzyme (ACE) gene is associated with element imbalances in hypertension. The concentrations of elements in genetically predisposed to hypertension rats (SHRs) and their controls (WKY rats) were also examined.

The aim of the study was to evaluate the association between the angiotensin-converting enzyme ACE I/D (rs4340) polymorphism and DNA damage in pati-ents with essential hypertension (EH). The I/D polymorphism of ACE was determined by polymerase chain reaction in 170 male hypertensive patients and 64 normotensive blood donors. We used flow cytometry to determine the levels of cell death, micronuclei and accumulation of peripheral blood leukocytes in G1/G0, S, G2/M phases of the cell cycle.
