Objective: To study the effect of silverionized drinking water on erythrocyte membrane fluidity, serum lipids and vascular endothelial cells in tail-suspended rats.
Method: Thirty male SD rats were randomly divided into ground control group (GC), simulated weightlessness control group (SC), simulated weightlessness and silverionized water drinking group (SS). Number of circulating endothelial cells (CEC), serum lipids and erythrocyte membranes fluidity was measured on the 21st day of tail suspension.
Result: Levels of serum TC, TG, HDL-C, HDL-C/TC and erythrocyte membrane fluidity in SC rats were significantly lower than those in GC rats; LDL-C/HDL-C ratio and number of CEC in SC rats were markedly higher than those in GC rats. Levels of serum TC, LDL-C and LDL-C/HDL-C in SS rats were higher than those in SC rats; HDL-C/TC ratio and erythrocyte membrane fluidity in SS rats were lower than those in SC rats.
Conclusion: Drinking silverionized water has a negative effect on lipid metabolism in tail-suspended rats.
