RESUMEN
For all patients and controls serum total cholesterol [TC], serum triglycerides [TG], serum high density lipoprotein cholesterol [HDL-c] were estimated colorimetrically and also serum apolipoproteins [apo A, A1 and B] were assayed by immunodiffusion. BHF and PHC patients showed significant decreases in the mean values of serum TC, TG, HDL-c an apo A, A1 and B compared to controls. Also PHC patients showed significant decreases in serum levels of the same parameters compared to BHF patients. Although the serum levels of HDL-c and apo A1 were significantly decreased in both groups of patients, yet the mean value of apo A1/apo B ratio was higher in both groups compared to controls and the rise was statistically significant in BHF patients and insignificant in PHC patients. Also there was a significant reduction of the serum levels of HDL-c and apo A1 in PHC compared to BHF patients and comparison of the mean value of apo A1/apo B ratio in the two groups was found to be statistically insignificant
