Some ultrastructural observations on the intestinal mucosa of the toad (Bufo melanostictus).

Abstract: An ultrastructural study of the mucous membrane of the small intestine in the toal (Bufo melanostictus) has shown that in the epithelium, besides the typical epithelial lining cells, non-epithelial cell types, including lymphocytes, macrophases, plasma cells, eosinophils and neutrophils are present These non-epithelial cell types are also encountered in the lamina propria, which also contains numerous fibroblasts, smooth muscle cells and mast cells The ultrastructural features of toad intestinal mucous membrane thus resembles that in mamals in many of its features, The intraepithelial localization of macrophages and of mature plasma cells is unusual The observations suggest that the toad intestinal mucous membrane may function as a lymphoepithelial organ

Sarcophaga ruficornis Fabr. (Sarcophagidae: Diptera) as a parasite of the common Indian toad

Abstract: Laravae ofSarcophaga ruficornis (Sarcophagidae: Diptera) have been found to cause wound myiasis in toads (Bufo melanostictus) in Siliguri, West Bengal. Along with mechanical wounds on the body, the eyes and paratoid glands of the toads are also attacked, and at an early stage of infection these organs appear swollen. The larvae feed on the tissue of the toads for about 100 to 110 hr, and the pupal development period lasts for 9–10 days. Infected toads die in about 3 days.

Testicular Leydig cells and 277-1277-1277-1dehydrogenase in cadmium-treated toads (Bufo melanostictus)

Abstract: Injection of cadmium chloride in toad increased Leydig cell size (area) and Δ5-3β-hydroxysteroid dehydrogenase activity in the testis.
