Epithelial body III of Tiliqua occipitalis and Trachysaurus rugosus has been the subject of a histological and cytochemical investigation with the object of making a comparison with the mammalian parathyroid gland. The cytochemical reactions of the reptilian chief cell are similar to those of the mammalian ‘pale principal’ cell. On the basis of a series of cytological and cytochemical changes a secretory cycle commencing with the chief cell and culminating in the water-clear cell is postulated. Two further cell types distinguished as the dark cell and the ‘epithelial’ cell have been described in the reptilian epithelial body. The significance of these two cell types is discussed. There is some evidence suggesting that true sinusoids invest the cellular cords. There is no evidence, with the technique used, that the gland cells are innervated. It is suggested that the general histology is comparable to that of the mammalian parathyroid gland.

Cisplatin (CDDP) a potent antitumor agent suffers from severe toxic side effects with nephrotoxicity being the major dose-limiting factor, The primary mechanism of its action has been proposed to be through its cross-linking DNA strands. It has also been shown to inactivate various transport enzymes and induce hypocalcemia and hypomagnesemia that may be the underlying cause for some of its toxicities. The present is an effort to study its influence on the parathyroid gland for any hormonal changes that control calcium levels in the body.Male Swiss Wistar rats (Crl: (WI) BR) weighing 200-300 g and of 60 days in age were injected (ip) with cisplatin (7mg/kg in normal saline). The controls received saline injections only. The animals were injected (iv) with calcium (0.5 ml of 10% calcium gluconate/day) and were killed by decapitation on day 1 through 5. Trunk blood was collected in heparinized tubes.
