Abstract:
Objective To investigate the chronic inflammation causing effect of nanobacteria(NB) on the prostates of SD rats,and to provide experiment evidence for etiology of type Ⅲ prostatitis.Methods Forty adult,male rats were divided into model group(16 rats),treatment group(8 rats) and control group(16 rats) at random.The rats in model group and treatment group were reproduced by infusing NB suspension transurethrally,and the animals of control group received an infusion of normal saline.After 4 weeks,WBC,lecithine and pathological changes of prostates were observed in model group(8 rats) and control group(8 rats).Tetracycline(100 mg?kg-1?d-1) was administered to treatment group,and distilled water were given to other groups respectively for 4 weeks.Then all rats were sacrificed,and the same detections were done as before.NB from prostates of animal were re-isolated,cultured and identified.Results After 4 weeks,chronic inflammation were observed in model group.WBC became significantly higher and lecithine of prostates were lower in model group than in control group(P0.05).The positive cases of NB were 16 in model group,and none in control group.Conclusion Nanobacteria causes chronic inflammation in SD rat prostates.NB maybe the etiological agent of type Ⅲ prostatitis.Anti-NB treatment by tetracycline is effective for this inflammation.
