Saw palmetto extract (SPE), an extract from the ripe berries of the American dwarf palm, has been widely used as a therapeutic remedy for urinary dysfunction due to benign prostatic hyperplasia (BPH) in Europe. Numerous mechanisms of action have been proposed for SPE, including the inhibition of 5a-reductase. Today, al-adrenoceptor antagonists and muscarinic cholinoceptor antagonists are commonly used in the treatment of men with voiding symptoms secondary to BPH. The improvement of voiding symptoms in patients taking SPE may arise from its binding to pharmacologically relevant receptors in the lower urinary tract, such as al-adrenoceptors, muscarinic cholinoceptors, 1,4-dihyropyridine receptors and vanilloid receptors. Furthermore, oral administration of SPE has been shown to attenuate the up-regulation of α1-adrenoceptors in the rat prostate induced by testosterone. Thus, SPE at clinically relevant doses may exert a direct effect on the pharmacological receptors in the lower urinary tract, thereby improving urinary dysfunction in patients with BPH and an overactive bladder. SPE does not have interactions with co-administered drugs or serious adverse events in blood biochemical parameters, suggestive of its relative safety, even with long-term intake. Clinical trials (placebo-controlled and active-controlled trials) of SPE conducted in men with BPH were also reviewed. This review should contribute to the understanding of the pharmacological effects of SPE in the treatment of patients with BPH and associated lower urinary tract symptoms (LUTS). 相似文献

Serum levels of CA15-3, a mammary tumor associated antigen recognizedby two different murine monoclonal antibodies (115D8 and DF3),were investigated in patients with mammary carcinoma and otherbenign or malignant diseases. The reference value of the serumCA15-3 level was obtained as 24 units/ml at the 99% confidencelimit among healthy individuals (n = 462). Elevation of serumCA15-3 levels was observed in 24.3% of overall patients withmammary carcinoma. Serum CA15-3 levels in breast cancer patientscorrelated with the clinical stage; higher percentages of positivitywere observed in those with advanced breast cancer (stage IV,64.7%, recurrent, 52.4% and metastatic, 70.3%). Furthermore,elevated serum CA15-3 levels in breast cancer patients respondedwell to the effect of therapy. Although the serum CA15-3 testgave percentages of positivity of breast cancer similar to thosefound by the serum CEA test, the serum CA15-3 test revealedlower percentages of posi-tivity than the serum CEA test amongpatients with benign breast lesions, liver cirrhosis or othercarcinomas. These results suggest that the serum CA15-3 antigenlevel provides a very useful marker for diagnosis and clinicalmonitoring of patients with breast cancer. 相似文献

This study aimed to develop a questionnaire on the quality of working life among female medical and healthcare professionals and examine its validity and reliability. The questionnaire was developed from an item pool drawing on the literature. The four trait scales included 40 items, covering female-specific stress in continuing a career, stress of lifestyle in maintaining personal values, job satisfaction and social support network. The questionnaire’s validity and reliability were assessed using data from 1,784 female doctors, dentists, and nurses. Validity was examined using exploratory factor analysis on each trait for construct validity, and multitrait scaling analysis for convergent and discriminant validity. Reliability was tested using Cronbach’s alpha for trait subscales and scales. Exploratory factor analysis on each trait was convergent. One trait derived three subscales, and another two. The remaining two traits were convergent for one factor. Multitrait scaling analysis showed that all scales and subscales were independent. The questionnaire was therefore internally consistent and had construct validity. Cronbach’s alpha was 0.85 for the total and between 0.72 and 0.83 for the subscales. These results validate the four-trait combination questionnaire and suggest that it would be suitable for use in future research, perhaps in combination with other existing scales. 相似文献

OBJECTIVE: Pegylated interferon (PEG‐IFN) plus ribavirin (RBV) combination therapy is now a popular treatment for patients with chronic hepatitis C; however, the reported sustained virologic response (SVR) rate remains at nearly 50% in genotype 1b infected patients. Therefore, it is of clinical benefit to be able to predict the effect of combination therapy on individual patients earlier in the treatment. We estimated the predictive serum HCV core antigen levels for SVR in the early therapeutic stage of combination therapy. METHODS: The HCV core antigen in patients with high‐level HCV viremia, in whom standard PEG‐IFNα2b plus RBV combination therapy had been completed, was measured at baseline and at 3, 7, 14, 28 and 84 days of treatment, and their SVR was determined at 24 weeks after treatment. Sixty genotype 1b‐ and 30 genotype 2‐infected patients were included. RESULTS: Thirty (50%) genotype 1b and 27 (90%) genotype 2 patients achieved a SVR. In genotype 1b patients the decline of HCV core antigen levels was statistically different between the SVR and non‐SVR groups. When we defined a separation level at 500 fmol/L, sensitivity, specificity, positive predictive value, negative predictive value, and accuracy for SVR at day 7 was 79.4%, 88.5%, 90%, 76.7%, and 83.3%, respectively. In genotype 2 patients, there was no significant difference in the HCV core antigen values between the SVR and non‐SVR groups. CONCLUSION: In genotype 1b patients, 500 fmol/L of HCV core antigen level at day 7 was the best predictor for therapeutic response in the early stage of treatment. 相似文献

Background: Mapping of recurrent atrial tachycardia (AT) after extensive ablation for long-lasting persistent atrial fibrillation (AF) is complex. We sought to describe the electrophysiological characteristics of localized reentry occurring after ablation of long-lasting persistent AF.
Methods: Out of 70 patients undergoing catheter ablation of long-lasting persistent AF, 9 patients (13%, 55 ± 8 years, 8 males) in whom localized reentry was demonstrated in a repeat ablation were studied. Localized reentry was defined as reentry in which the circuit was localized to a small area and did not have a central obstacle. The mechanism of AT was determined by electroanatomical and entrainment mapping.
Results: Nine localized reentries with cycle length of 243 ± 41 ms were mapped in 9 patients. The location of AT was the left atrial appendage in 4 patients, anterior left atrium in 2, left septum in 2, and mitral isthmus in 1. In all ATs, a critical isthmus of <10 mm in width was identified in the vicinity of the prior linear lesions or ostia of isolated pulmonary veins. Ablation of the critical isthmus, which was characterized by continuous low-voltage activity (median voltage: 0.15 mV, mean duration: 117 ± 31 ms), terminated AT and rendered it noninducible. Additionally, ablation was performed for all of inducible ATs. At 11 ± 7 months after the procedure, 8 of 9 patients (89%) were free from any arrhythmias.
Conclusions: After ablation of long-lasting persistent AF, localized reentry may arise from a site in the vicinity of the prior ablation lesions. Ablation of the critical isthmus eliminates the arrhythmia. 相似文献
