AIM: To observe the changes of tyrosine hydroxylase protein levels and the density of dopaminergic amacrine cells before and after the administering brain derived neurotrophic factor protein into the vitreous cavities of streptozotocin reduced Wistar diabetic rats.

目的：观察玻璃体腔内注射脑源性神经营养因子（Brain derived neurotrophic factor，BDNF）前后STZ糖尿病大鼠视网膜中酪氨酸羟化酶（tyrosine hydroxylase，TH）的水平及多巴胺能无长突细胞数目的变化。

METHODS: Adult male Wistar rats, 9 weeks of age, were injected intraperitoneally with STZ to create diabetes. At 2 week after the models were created, BDNF protein was administered into the vitreous cavities of rats. At 4 week after the models were created, the rats were killed and the retina was removed for Western blotting and Whole-mount immunohistochemistry for TH to observe the changes of TH and dopaminergic amacrine cells in retina.

The works in the project just done can be summarized as five respects.(1) A device was designed to fabricate the asymmetrical resonant cavities by a pendant drop. A series ARCs with variable parameters provides a valuable experimental method for investigating the characteristics of ARCs.(2) The relationship between the number of active modes and the shape parameters in an ARC was investigated. The experimental lasing threshold was compared with theoretical result, the good agreement between two shown that it was the decrease of the number of active modes in an ARC that decreased lasing threshold.(3) Dye lasing gain was used to enhance the signals of stimulated Raman scattering of the weak gain Raman modes in a circular cavity made by a pendant drop, the instantaneous SRS spectra of weak gain Raman modes in ethanol was obtained by this new method.(4) The SRS signals of minority compound in a binary chemical complex was obtained by using dye lasing gain method. The detection concentration of minority compound was reduced to an order compared with normal SRS method.(5) A cylindrical circular cavity was formed by a liquid jet, which was used to reduce the pump intensity required for laser induced plasma spectroscopy. The limit of detection of trace element in aqueous sample was greatly decreased by this new method.
