Abstract

To examine the effects of sex-hormones on lipids, lipoproteins and coagulation in the normal menstrual cycle 37 women had blood samples taken early in the follicular phase (low estrogen) at the midcycle (high estrogen) and late in the luteal phase (high estrogen and high progesterone) under the best possible uniform and basal conditions. No significant changes (P greater than 0.05) in lipids and lipoproteins (including the HDL subfractions and apolipoproteins) were found throughout the menstrual cycle. In the coagulation system antithrombin III and factor VII did not change (P greater than 0.05). Fibrinogen, however, showed a significant (P less than 0.05) increase in the luteal phase compared to the follicular phase and midcycle. Fibrinogen showed a significant positive correlation (r = 0.2766; P less than 0.01) with progesterone, so the rise in fibrinogen in the luteal phase could be a progesterone effect. This longitudinal study performed on a large number of women under basal conditions showed that it seems of minor importance to define exact days of the cycle for analysing lipids and lipoproteins e.g. as controls in a study of lipid metabolism in women taking sex-hormones. For coagulation studies the cycle days may, howeve...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.

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
