Effects of minocycline on expression of bcl-2, bax in early retinal neuropathy of diabetes in rats.
AIM
To study the effect of the minocycline (MNC) on expression of bcl-2, bax in retinal nerve cells of rat with diabetes.


METHODS
Male SD rats were randomly divided into negative control group, model control group and MNC treated group. Diabetes model was established by intraperitoneal injection of 60 mg/kg streptozotocin (STZ). The protein expressions of bcl-2 and bax in retina were detected by immunohistochemistry method.


RESULTS
Compared with the negative control group, bax immunoreactive neurons in retina were increased significantly (P<0.01) in model control group. However, bax immunoreactive neurons in retina in MNC treated group were significantly decreased (P<0.01). Compared with the model control group, bcl-2 immunoreactive neurons in retina were increased significantly(P<0.01) in MNC treated group.


CONCLUSION
MNC can obviously decreased expression of bax and increased expression of bcl-2 in retina with DR. It is one of path of inhibiting impairment on retinal nerve cells with DR.
