Effects of oral contraceptives on total serum proteins, albumin, globulins and cholesterol levels in Ibadan, Nigeria.

Total serum protein, albumin, globulin, albumin/globulin ratio and cholesterol levels were determined in 25 subjects on oral contraceptives and 25 controls. The mean serum total protein, globulin and cholesterol levels were significantly increased in oral contraceptive and their control counterparts. The albumin/globulin ratio in subjects on oral contraceptives users is significantly decreased compared with controls.

Changes in electrolytes, urea and creatinine excretion during dry and wet seasons.

Twenty-four-hour urine samples were collected from 179 male and female medical students in Ibadan, and 112 medical students in Zaria. The values for 24-h urine volume, urinary electrolytes, urea and creatinine exhibited a skewed distribution and were normalized by logarithmic transformation. The geometric means values for the 24-h urine volume for the dry season were significantly less than those for the wet season in Ibadan and Zaria.
