Abstract
Hypercalcemia was induced in Clarias batrachus by treating them with vitamin D3 (5,000 I.U./100 g body wt.) and/or 0.5% solution of CaCl2. The animals were killed on 1st, 3rd, 5th, 9th, 13th and 17th days after the initiation of the experiment. Histological preparations of the ultimobranchial gland (UBG) were made. The gland exhibits nuclear hypertrophy, hyperplasia and loss of staining response corresponding to the rise in serum calcium levels. At later intervals, the UBG shows exhaustion and degeneration which is evident from vacuolization and nuclear shrinkage of the ultimobranchial cells after day 13 in groups B and C and day 9 in group D.
