TL;DR: A quantitative study of seminiferous tubules in toad treated with a single subcutaneous injection of cadmium chloride, showed that 7 days after Cadmium injection some stages of spermatogenesis consisting of secondary sper matogonia and primary sperMatocytes were decreased significantly.

TL;DR: The first experimental vitiligo responding to treatment with psoralene has been developed using Bufo melanostictus, and it is shown that the depigmentation produced by the tyrosinase inhibitors hydroquinone and catechol is counteracted by psoralenes.

TL;DR: The exposure to high temperature may have arrested spermatogenesis and affected Leydig cell function in toads exposed to 48 degrees C.
Abstract: A quantitative study of changes in the seminiferous tubule and the measurement of Leydig cell area were performed in the testis of toads exposed to 48 degrees C for 8 days The frequency of occurrence of stages I and II was not affected whereas stages III and IV were influenced by the exposure to heat The number of primary spermatocytes and secondary spermatocytes in stages III and IV were significantly decreased The spermatocytes in stages III and IV were injured in the exposed toads The area of Leydig cells including their nuclei was also decreased in the testes of heat exposed toads It is concluded that the exposure to high temperature may have arrested spermatogenesis and affected Leydig cell function

TL;DR: A simple and modified dorsal approach method has been made in the toad's (Bufo melanostictus) sciatic gastrocnemius nerve-musle preparation that incurs less blood loss, time consumption, nerve damage and visceral spoil compared to conventional ventral approach method.
