Effects of drinking purified-water on blood lipid and correlative indexes

  Objective   To examine whether feeding with purified-water for a long time had effects on blood lipid and correlative indexes of rats.

  Methods   Three groups of female rats were included.The rats were received tap-water, purified -water and purified-water with 0.5 g of magnesium sulfate perliter.All rats were fed with basic food for five months.During this time, blood was drown by way of tail vein at the end of every month for dynamic determination of TC, TG, HDL-c, LDL-c, Ca²⁺, Mg²⁺ and MDA.Rats were phlebotomized through femora then killed for mesuring TC, TG, HDL, LDL, Ca²⁺, Mg²⁺ at the end of the experiment.

  Results   Purified-water rats had lower Mg²⁺ level while higher levels of blood TC, TG, LDL and MDA compared with the other two groups.

  Conclusion   Drinking purfied-water for a long time could result in the deficiency of blood Mg²⁺ while increasing rat's blood lipid(TC, TG, LDL)and MDA, which would do harm to the cardiovascular system.
