    Mechanisms of Toxic Effect of Streptozotocin on β-Cells in the Islets of Langerhans

    Administration of streptozotocin caused selective damage to endocrine β-cells in rat pancreatic islets, which was related to activation of apoptosis. The cytotoxic effect of streptozotocin was associated not o...
