Description

The hematological and serum biochemical values of a total of 18 pregnant female squirrel monkeys were determined during the pre-and postpartum period. Pregnancy was determined by abdominal palpation in adult females cohabiting with robust males. The mean body weight of the pregnant females gradually increased toward parturition and dramatically decreased at parturition due to delivery of the infant monkey. The red blood cell count, hematocrit and hemoglobin levels diminished toward parturition and then increased to their normal levels by week 6 after delivery. The Wintrobe constant, MCHC, did not fluctuate, but MCH and MCV values increased in late pregnancy and the early nursing periods. The mean white blood cell count varied between 65.8 and 87.3 (× 102/mm 3) during the experimental periods. The mean serum total cholesterol concentration and glutamic-oxaloacetic transaminase activity were lower in the pregnant group during the mid- and late gestation stage than in nonpregnant and nursing females. The mean serum total protein and albumin values were lower in pregnant females than in the controls. Alkaline phosphatase activity increased in late pregnancy and the nursing periods. Since the pregnant females examined gave birth to healthy newborn monkeys and nursed them normally, the hematological and serum biochemical measurements should represent the physiological values for squirrel monkeys during pregnancy and the postpartum period.<br>
