[The islands of Langerhans in rats (Rattus norvegicus, Forma alba) following administration of prednisolone - semi-quantitative light and electron microscopy study].
Light microscopic-histological and ultrastructural alterations of rat pancreatic islands and their A- and B-cells were studied after daily injections of prednisolone suspension in a high dosage. After 7 respectively 14 d we noted light microscopically an enlargement of islands, caused by an island cell hypertrophy and hyperplasia. Electron microscopically we found a remarkable degranulation and vacuolization of islands B-cells and a significant enlargement of A-cell granules. The observed alterations were discussed in respect to the prednisolone stress.
