This study was carried out to understand the effects of Saengchinyanghyoltang-gamibang (SGT) on pancreatic islets of the mice induced with streptozotocin (STZ). In the control group, two times injected with 50 mg/kg 572 at 24-hour intervals, a few number of insulin immunoreactive-cells are observed at the pancreatic islets of the mice. In the experimental group which administered with extract of SGT during 21-day, a number of immunoreactive-cells are observed at the pancreatic islets. According to the electron microscopic observation, $\beta-cells$ of the control group were contained a few of secretory granules, but also these granules were contained electro-lucent materials. In the experimental group, a lot o( secretory granules and well developed cell organelles are observed at the $\beta-cells$. The level of glucose was significantly decreased in the experimental group compared with control group, but the level of BUN was similar in these two groups. These results suggest that administration of SGT to the mice improved the damage of $\beta-cells$ from injected with STZ.
