ABSTRACT

Objective To reproduce an SD rat model of prostatic calculus by using nanobacteria (NB), and explore the role of NB in contributing to prostatitis and prostatic calculus. Methods Twenty adult male SD rats were randomized to the control group and 20 to the model group. Rat prostate infection models were reproduced by infusing 0. 2 ml (Concentration, 1 Mai unit) NB suspension transurethrally. 0.2 ml physiological saline was infused transurethrally in the rat control group. The rats were sacrificed 4 and 8 weeks later and prostatic pathology were viewed by hematoxylin and eosin (HE) staining. Lithogenesis was observed by scanning electron microscope (SEM) or Transmission electron microscopy (TEM). Re-isolation, culture and identification of nanobacteria were also done in rat prostatic tissues. Results Chronic inflammatory changes of prostates were shown in the model group at both 4 weeks and 8 weeks after infusing NB suspension. Prostatic calculi were detected by SEM and TEM at 8 weeks in the prostates of the rat model group (7/10). Neither chronic inflammatory changes nor prostatic calculus was found in the control group. NB was positive in the model group, but negative in the control group. Conclusions NB infection could cause chronic prostatitis and prostatic calculus in rats.

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.

ABSTRACT

Objective To evaluate the efficacy and safety of two-dose basiliximab vs two-dose daclizumab for prevention of acute rejection in renal transplantation. Methods A total of 58 renal transplant recipients were randomized into 2 groups:basiliximab group ( n =30) and daclizumab group ( n =28).All the cases received the triple therapy of cyclosporine,mycophenolate mofetil and prednisolone (CsA+MMF+Pred).The 3 medications were administered as follows.For CsA,initial dose of 6 mg/kg per day was downtitrated to 4~5 mg/kg per day at 3 months,then to 3~4 mg/kg per day at 6 months.For MMF,initial dose of 0.5 g,3 times per day was downtitrated to 0.5 g,twice per day at 1 month.For Pred,initial dose of 30 mg per day was downtitrated to 20 mg per day at 3 weeks,then to 10~15 mg per day at 6 months.Basiliximab group received two-dose basiliximab (20 mg intravenous infusion) 2 hours before operation and 4 days after transplantation.Daclizumab group received two-dose daclizumab (50 mg) 1 day before operation and 14 days after transplantation.Postoperatively,acute rejection was monitored for 6 months,and adverse events and person/allograft survival were observed for 6~12 months.CD25 + cell count was tested using Beckman Coulter flow cytometer before operation and postoperatively once a week for 2 months. Results During 6-month follow-up, the number of acute rejection episodes were 5 in daclizumab group and none in basiliximab group ( P

ABSTRACT

Objective To investigate the clinical diagnosis and treatment of pneumocystis carinii pneumonia(PCP) after kidney transplantation. Methods Eight patients who developed PCP between 90 days and 140 days following renal transplantation were enrolled in this study.All of them were male with a mean age of 28 years.The clinical manifestations,accessory examinations and treatment were retrospectively analyzed. Results All the 8 patients fully recovered.With early diagnosis and administration of compound sulfamethoxazole(SMZ),clinical symptoms of 6 patients were rapidly controlled within 5 to 7 days.Because of delayed diagnosis and treatment,the conditions of the other 2 cases were more severe and were controlled within 25 days and 46 days separately. Conclusions Application of percutaneous pneumocentesis biopsy can be useful for correct diagnosis in early stage of PCP and has high positive rate of the pathogen. Most PCP patients can be cured with early use of SMZ.Types and doses of immunosuppressor should be adjusted properly.

ABSTRACT

0.05 ). In Zenapax and OKT3 groups, 1 and 2 allografts were removed as a result of rupture respectively. 4 cases were suffered from delayed graft function(DGF) in Zenapax group and 9 in OKT3 group respectively with the difference being significant ( P
