Abstract

In this longitudinal study involving 100 Singaporean acceptors, the effects of Norplant on metabolic function was evaluated. With respect to liver function, the results at the end of two years still indicate the presence of possible hepatocellular dysfunction. Despite a 4.5% decrease in serum bilirubin during the second year, the mean serum bilirubin still remained significantly raised (p less than 0.001). Furthermore there was a significant fall in total proteins and globulin during the period under review (p less than 0.001). However mean levels of all three parameters remained within the normal clinical range. As regards lipid metabolism, the total triglycerides and total cholesterol still remained significantly decreased at the end of two years (p less than 0.001). The LDL-cholesterol, which was significantly decreased at the end of one year, increased by 2.2% during the second year. However, this rise in LDL-cholesterol was not significant and was still below the preinsertion level. The HDL-cholesterol levels returned to their preinsertion levels after a significant increase in the first year. The HDL-cholesterol/Total cholesterol - HDL-cholesterol ratio returned to its preinsertion value at the end of two years while the ...Continue Reading

ApoE, Lipids & Cholesterol

Serum cholesterol, triglycerides, apolipoprotein B (APOB)-containing lipoproteins (very low-density lipoprotein (VLDL), immediate-density lipoprotein (IDL), and low-density lipoprotein (LDL), lipoprotein A (LPA)) and the total cholesterol/high-density lipoprotein (HDL) cholesterol ratio are all connected in diseases. Here is the latest research.
