Effect of Dried Lake Salt (Kanwa) on Lipid profile and Heart Histology of Female Albino Rats

Abstract

Peripatum cardiomyopathy is a devastating form of cardiac failure affecting women mainly in their last month of pregnancy or early postpartum with high incidence in Northern Nigeria where the consumption of dried lake salt postpartum is high. The current work was designed to study the effect of dried lake salt on lipid profile and histology of heart in female albino rats. The rats were administered graded doses of the salt for 4 weeks. The group administered 300mg/kg body weight of the dried lake salt has significantly (P<0.05) lower high density lipoprotein-cholesterol as compared with the control. There was no significant (P>0.05) increase in low density lipoprotein-cholesterol but total cholesterol, triglyceride and very low density lipoprotein- cholesterol levels were lower compared to the control. Atherogenic index of the group administered 300mg/kg body weight was significantly (P<0.05) higher compared to the control. The histological examinations of section of the heart reveal chamber dilation, hypertrophy and focal atrophy. The study suggests that consumption of dried lake salt for 4 weeks caused alteration to heart tissue and may cause heart related diseases in rats.
