Abstract

Carbimazole (CBZ) is an anti-thyroid drug commonly used in the treatment of hyperthyroidism. The objective of this study was to evaluate the effects of dose level of CBZ on thermoregulation and blood constituents in mature male rabbits. Twenty animals were assigned to 4 groups (A, B, C, D) of 5 each. Group A served as control and treated animals in groups B,C,D, received daily orally CBZ doses of 10, 15 and 20 mg/animal for 3 weeks, respectively. The values of rectal temperature (Tr,), respiration rate (RR) and heart rate (HR) decreased in treated rabbits and the mean values of HR decreased with increase in the dose level of CBZ. The packed cell volume (PCV), Hb concentration and total leukocyte count (TLC) were lower in CBZ treated rabbits. Serum levels of total protein and globulins increased and serum albumin level decreased in treated groups of rabbits. Serum urea level was lower in CBZ treated groups and there was an increase in serum urea level with increase in CBZ dose level. Serum cholesterol level was higher in treated groups and there was an increase in serum cholesterol level with increase in CBZ dose level. Plasma glucose level decreased significantly in CBZ treated groups compared with the control and the mean values decreased with increase in the dose level of CBZ. The results indicate that the responses of basic physiological parameters were almost dose dependent in the range adopted in this study.
