ABSTRACT
OBJECTIVE:To investigate the improvement effect of Prostatitis capsule on chronic non-bacterial prostatitis(CNP) model rats. METHODS:60 rats were randomly divided into sham operation group (distilled water),model group (distilled wa-ter),Pule'an tablet group(positive control,2 g/kg)and Prostatitis capsule high-dose,medium-dose,low-dose groups(16,8,4 g/kg). Except for sham operation group,other 5 groups were injected Xiaozhiling injection 0.2 mL to reduce CNP model. After 7 d of modeling,they received related medicines,ig,once a day,for 45 d. After 24 h of last administration,prostate lesions were ob-served by eyes and wet quality was weighed. White blood cell(WBC)count and lecithin body(SPL)count were conducted under microscope,and prostate tissue slices were pathologically observed. RESULTS:Compared with sham operation group,prostate showed gray nodules,adhesion in glands and surrounding tissue;wet quality of prostate and WBC,SPL count in prostate tissue were significantly increased(P<0.01);under microscope,there were significant congestion,edema and a variety of inflammatory cell infiltration in prostate interstitial. Compared with model group,gray nodules in prostate in Pule'an tablet group and Prostatitis capsule group were reduced,as well as adhesion degree in prostate and surrounding tissue;wet quality of prostate and WBC,SPL count in prostate tissue were significantly decreased(P<0.01);pathological changes had improved to varying degrees under micro-scope,especially the changes in Prostatitis capsule high-dose group,and prostate tissue only showed mild congestion,edema and little inflammatory cell infiltration. CONCLUSIONS:Prostatitis capsule has a certain improvement effect on CNP model rats.
ABSTRACT
Objective:To explore the effect of the methanol extract of Macrothelypteris oligophlebia on chronic non-bacterial prosta-titis ( CNP) in rats to confirm the active fractions. Methods:The powdered rhizomes of M. oligophlebia were soaked in methanol. The methanol extract was suspended in water and then extracted successively with chloroform and ethyl acetate to obtain chloroform fraction, ethyl acetate fraction and water fraction. Carrageenan-induced CNP in rats was established. The rats were randomly divided into the sham-operated control group, model group, positive control group, methanol extract group, ethyl acetate fraction group, chloroform fraction group and water fraction group. The anti-prostatitis effect was evaluated by the prostate index, and the pathological examination of prostate was performed using HE staining. The levels of interleukin-10 (IL-10), tumor necrosis factor alpha (TNF-α), cyclooxyge-nase-2 (COX-2) and prostaglandin E2(PGE2) were analyzed using ELISA kits. Results:The ethyl acetate fraction group and metha-nol extract group with high flavonoid content could significantly decrease prostate index (P<0. 01) and the levels of IL-10, TNF-α, COX-2 and PGE2(P<0. 05 or P<0. 01), and improve the prostate morphology when compared with the model group, especially with the ethyl acetate fraction group. Conclusion:The rhizomes of M. oligophlebia show promising therapeutic effect on CNP, and the ethyl acetate fraction is the active fraction.
ABSTRACT
Objective To study the action of Mycoplasma genitulium (Mg) in pathogenesis of chronic non-bacterial prostatitis. Methods Mg culture and polymerase chain reaction (PCR) were perfomed on prostatic secretion specimens from 987 patients with chronic non-bacterial pristatitis and 125 healthy men. Results ①The positive rate of Mg in the prostatic secretion from the 987 patients was 31.5% (302/987). Among the 302 positive cases, 153 cases had other pathogens, of which Ureaplasma urealyticum (Uu) was the most (128). ②In the controls, the positive rate of Mg was 2. 53% (3/125). The difference between the two groups was statistically significant (X2=44. 32,P
