Efficacy of Prostant on chronic prostatitis in 119 patients. (1/8)

AIM: To evaluate the efficacy and safety of Prostant in the treatment of chronic prostatitis. METHODS: One hundred and nineteen cases of patients who had been diagnosed of chronic prostatitis were treated by Prostant. The efficacy was evaluated by WBC in EPS and NIH Chronic Prostatitis Symptom Index after a one-month follow-up. RESULTS: After the one-month follow-up, the total improvement rate is 65.5 %, the WBC in the prostatic fluid were reduced from (21+/-20) to (12+/-13)/High-power field (HPF); the symptom index score changed from 12+/-4 to 7+/-5. The pain and voiding score of the symptom index were lowered from 8+/-3 to 5+/-3 and 3.9+/-2.7 to 2.3+/-2.3 respectively. All of above showed great statistic differences (P<0.05). Only 2 cases (1.7 %) reported serious diarrhea. CONCLUSION: The Prostant is effective and safe in the treatment of chronic prostatitis, especially on those cases whose symptom and inflammation in prostatic fluid are not too serious.  (+info)

Constituents of leaves of Phellodendron japonicum MAXIM. and their antioxidant activity. (2/8)

Three new flavonoid derivatives, 6'''-O-acetyl amurensin (1), 6'''-O-acetyl phellamurin (3) and (2R)-phellodensin-F (5), together with thirty known compounds have been isolated from the leaves of Phellodendron japonicum MAXIM. Their structures were established by means of spectroscopic analysis, including extensive 2D NMR and Mass spectra. The known compounds were identified by comparison with published physical and spectral data. The isolated compounds were screened for their in vitro antioxidant activity through DPPH (1,1-diphenyl-2-picrylhydrazyl) radical scavenging assay. Compounds quercetin and phellodenin-A demonstrated significant radical scavenging activity.  (+info)

Akt-and CREB-mediated prostate cancer cell proliferation inhibition by Nexrutine, a Phellodendron amurense extract. (3/8)

Evidence from epidemiological studies suggests that plant-based diets can reduce the risk of prostate cancer. However, very little information is available concerning the use of botanicals in preventing prostate cancer. As a first step toward developing botanicals as prostate cancer preventives, we examined the effect of Nexrutine on human prostate cancer cells. Nexrutine is a herbal extract developed from Phellodendron amurense. Phellodendron extracts have been used traditionally in Chinese medicine for hundreds of years as an antidiarrheal, astringent, and anti-inflammatory agent. The present study investigated its potential antitumor effect on human prostate cancer cells. Our results suggest that it inhibits tumor cell proliferation through apoptosis induction and inhibition of cell survival signaling. The results of the present study indicate that Nexrutine treatment 1) inhibits the proliferation of both androgen-responsive and androgen-independent human prostate cancer cells through induction of apoptosis; 2) reduces levels of pAkt, phosphorylated cAMP response-binding protein (pCREB) and CREB DNA-binding activity; and 3) induces apoptosis in prostate cancer cells stably overexpressing Bcl-2. Further, Akt kinase activity was reduced in cells treated with Nexrutine, and ectopic expression of myristoylated Akt protected from Nexrutine induced inhibition of proliferation, implicating a role for Akt signaling.  (+info)

Constituents from the leaves of Phellodendron amurense and their antioxidant activity. (4/8)

Three new coumarins, phellodenols F-H (1-3) and a new glutaric acid derivative, phellodendric acid-A (4) were isolated from the leaves of Phellodendron amurense together with twenty-nine known compounds. Extensive 1D and 2D NMR experiments and other spectroscopic studies were employed to determine the structures of 1-4. The isolated compounds were screened for their antioxidant activity through DPPH (alpha,alpha-diphenyl-beta-picrylhydrazyl) radical scavenging assay. Compounds quercetin, quercetin-3-O-beta-D-glucoside, quercetin-3-O-beta-D-galactoside and kaempferol-3-O-beta-D-glucoside demonstrated significant radical scavenging activity comparable to vitamin E.  (+info)

Simultaneous determination of contents of three active components in Jiejia tincture by HPLC method. (8/8)

The objective of the study was to determine the contents of three active components in Jiejia tincture by establishing HPLC method. Test articles were prepared by ultrasonic extraction. Separation was performed using a Kromasil C18 (250 mm x 4.6 mm, 5 microm) chromatographic column, and gradient elution was performed with acetonitrile-0.3% phosphoric acid solution as the mobile phase at a volumetric flow rate of 0.80 mL/min. The contents of catechin, baicalin and berberine in Jiejia tincture were determined at the wavelength of 276 nm and a column temperature of 30 square. The results revealed that catechin showed a good linear relationship at the range of 100 approximately 800 microg/mL (r=0.9997); baicalin showed a good linear relationship at the range of 15 approximately 120 microg/mL (r=0.9996), and berberine at the range of 7 approximately 56 microg/mL (r=0.9995). Their average recovery rates were 99.67% (RSD 1.01%, n=6), 98.7% (RSD 1.93%, n=6) and 100.5% (RSD 2.88%, n=6) respectively. The study concluded that the high-performance liquid chromatography established in this study was simple, accurate and reproducible, and can also be used in the determination of catechin, baicalin and berberine contents in Jiejia tincture.  (+info)
