[Influence of Zea mays L. saponin (ZMLS) on ultrastructure of kidney and pancreas in diabetes rats induced by streptozocin].

OBJECTIVE
To discuss the effect of Zea mays L. saponin (ZMLS) on ultrastructure of kidney and pancreas in the diabetes rats induced by streptozocin.


METHOD
The diabetic rat model was established by injections of STZ, blood glucose, the ultrastructure of the kidney and pancreas were observed.


RESULT
Compared with the model group, the large, middle-dose ZMLS groups and melbinum group could remarkably decrease the blood glucose (P < 0.01), the large, middle, small-dose ZMLS groups could remarkably prevent the pancreatic islet beta-cell from the injury induced by Streptozotocin. Melbinum and the large, middle-dose ZMLS groups could remarkably increase mitochondrial Vv, deltam and euchromatin Vv (P < 0.01), and significantly decrease the delta, Nucleus delta and heterochromatin Vv (P < 0.01). The small dose of ZMLS obviously increases mitochondrial Vv (P < 0.05).


CONCLUSION
ZMLS showed good effect on decreasing blood glucose and protection action on the kidney and pancreas injury of induced by STZ.
