title: Removal of olfactory bulbs in rats of different ages: repercussion on some metabolic constants.
abstract: The object of this investigation is to study effects of bulbectomy on female rats operated on at 15 and 30 days of age (prepubescent), 50 days (pubescent) and 120 days (adult), with respect to various parameters: these comprise corporal weight, liver weight, blood sugar, liver glycogen, glucose tolerance test and serum free fatty acid. Results were as follows. Body weight: in all groups this was significantly less than in controls except for rats operated on at adult age. Liver weight: (% of body weight) decreases in all groups, but significantly only in animals operated on when 15 days old. Blood sugar: significantly lessened in rats operated on when 30 and 120 days old. Liver glycogen: lessens in rats operated on at 30 and 120 days of age, but significantly only in the former. Glucose tolerance test: the coefficient k is found to increase in rats operated on at 15, 30 and 120 days of age; there is a significant increase in the first two groups. Serum free fatty acids: no marked alterations in any of the groups.
