Examination stress in medical student: a study.

The present study was conducted on 40 male and 10 female students appearing for the 1st MBBS examination. Two readings of pulse rate, blood pressure and electro cardiogram were taken viz 6 months (control) and 10 minutes prior to the examination. A significant increase was seen in the pulse rate and blood pressure readings before the examination as compared to the control readings. However, no significant change was observed in electro cardiographic recordings.

Serum protein profile in normal pregnancy and in relation to parity.

Forty pregnant females of third trimester and their twenty non-pregnant controls were screened for Hb%, PCV and serum protein differentials in relation to parity. Paper electrophoresis method revealed significant rise in mean levels of serum alpha 1, alpha 2 and beta-globulins in pregnant females as compared to non-pregnant controls, which may be due to the rise in pregnancy-associated-proteins. Radial immunodiffusion method revealed rise in mean serum IgM level with increasing parity, whereas a decrease in mean serum IgG level was observed which might be due to the placental membrane-transfer and/or decreased IgG synthesis. Haematological investigations revealed decreased Hb% and PCV which may have been caused both due to increased demand of nutrients as well as by haemodilution, associated with water retention during pregnancy.
