Objectives:To establish animal model of anterior proliferative vitreoretinopathy (aPVR) with cultured homologous dermal fibroblasts of rabbit, and to provide evidence why hypotony was caused by aPVR. Methods:Animal models of aPVR were established with cultured homologous dermal fibroblasts on pigmented rabbits. Rabbits were sacrificed on the 14th, 28th and 56th day after the operation to prepare naked eyes and to receive histological examinations. Results:Naked eye examination showed that the peripheral retina was detached by dragging in the experimental group 28 and 56 days postoperatively. Microscopic examination showed atrophy or absence of the non-pigmented ciliary epithelium on the 28th and 56th postoperative day in the experimental group. Conclusions:The epiciliary membrane in aPVR dragged the ciliary body, made atrophy of non-pigmented epithelium, which perhaps was the main cause of hypotony.

Objective To investigate the effect of astilbin on expressions of perforin and granzyme B in activated T cells of mouse heart transplantation model with acute rejection.Methods Cardiomyocytes of BALB/C mouse and spleen cells of C57BL/6 mouse were harvested and made into single cell suspensions.The cardiomyocytes(2?10~5 ml~(-1))as stimulators and spleen cells(1?10~6 ml~(-1)) as responsers were mixed and cultured.The model of mouse heart transplantation with acute rejection in vitro was therefore established.There were two groups in the experiment.Control group is the mixed culture of the cardiomyocytes and spleen cells;Astilbin group is the mixed culture of the cardiomyocytes and spleen cells with astilbin(15?g/ml).Apoptosis of T cells were analyzed by TUNEL assay.The expressions of perforin and granzyme B were measured by RT-PCR.Results Apoptosis of activated T cells in Astilbin group was significantly increased than that of the control group(P
