Resolution of hepatic fibrosis by traditional Chinese medicine. / CUHK electronic theses & dissertations collection

January 2005 (has links)
Both SM and ST reduced ALT elevation in rats in the prevention study. In the treatment study, ALT of all rats was resolved. Only ST reduced the fibrosis in both prevention and treatment studies. Maximum reduction of fibrosis compared to control was 44.12% in the prevention group and 56.83% in the treatment group. Activated HSC was decreased and apoptosis increased in rats with improved fibrosis. / Conclusion. ST prevented formation of liver fibrosis and promoted resolution of established fibrosis in the rat model. These effects were mediated through induction of HSC apoptosis in the liver. (Abstract shortened by UMI.) / Hepatic fibrosis results from the wound healing response to prolonged liver insult such as chronic hepatitis. It represents an imbalance of fibrogenesis and fibrolysis, causing formation of scars. Activation and proliferation of hepatic stellate cells (HSC) is a key to fibrogenesis while apoptosis of HSC is associated with resolution of fibrosis. / Intense efforts are currently underway to evaluate potential anti-fibrotic agents in herbal medicine. The study hypothesized that herbs may resolve hepatic fibrosis through induction of apoptosis of HSC. In this study, the anti-fibrotic potentials of fourteen commonly used herbs were examined. The anti-fibrotic effect and the underlying mechanism of two herbs were further investigated in an animal model. / Method. Fourteen herbs including Angelica sinensis(AS), Astragalus membranaceus(AM), Cordyceps sinensis(CS), Curcuma wenyujin(CW), Carthamus tinctorius(CT), Curcuma kwangsinensis(CK), Bupleurum chinensis(BC), Ligusticum chuanxiong(LC), Paeconia lactiflora(PL), Prunus persiea(PP), Poria cocos(PC), Salvia miltorrhiza(SM), Schisandra chinensis(SC) and Stephania tetrandra(ST) were selected for screening based on documented safety and effectiveness, and availability in commercial extracts. These two herbs were also authenticated by chemical profiling using HPLC. / Result. For in vitro bioassay, five herbs, namely Angelica sinensis (AS), Carthamus tinctorius (CT), Ligusticum chuanxiong(LC), Salvia miltiorrhiza(SM) and Stephania tetrandra(ST) demonstrated both anti-proliferative and pro-apoptotic activities in T6. SM and ST showed highest potencies with 51.63% and 44.52% of T6 cells showing apoptotsis respectively. Fas and Bax expression was up-regulated and BclxL expression decreased in HSC after incubation with SM and ST. Fas ligand and Bcl2 expression remained unchanged. / Treatment of chronic liver disease with herbal medicine has been documented in ancient China. Nowadays, practitioners of traditional Chinese medicine (TCM) also use herbs to treat chronic liver disease and it is conceivable that such herbs redress the imbalance between fibrogenesis and fibrolysis. / Chor Sin Yee. / "July 2005." / Adviser: Joseph J.

A pilot study to develop and validate a traditional Chinese medicine (TCM) questionnaire: a health status instrument for TCM assessment in patients with Osteoarthritis (OA) of the hip or knee

Wang, Ping Unknown Date (has links)
Research suggests acupuncture is potentially an effective treatment for osteoarthritis (OA) of the hip or knee. Essential for the evaluation of Chinese acupuncture treatment is the availability of a reliable and valid measurement. However, currently there is no appropriate measurement instrument validated within traditional Chinese medicine (TCM) concepts and frameworks. Objective is to develop and validate a TCM questionnaire as a health status instrument for TCM assessment in patients with OA of the hip and knee. Methods The TCM questionnaire was developed from TCM theory and clinical experience. The questionnaire was examined by experts, for content and faces validity and pre-tested on a volunteer sample of three subjects. The developed questionnaire was validated on a convenience sample of ten subjects from six different clinical settings in Auckland region. The practitioner or receptionist from the selected clinical sites handed out the questionnaire package to their patients who fulfilled the study criteria. Each patient (subject) completed the questionnaire on their arrival and the re-testing questionnaire at a two-week interval. The reliability of the questionnaire was estimated by examining the internal consistency reliability (Cronbach's alpha statistic) and test-retest reliability (Intra-class correlation coefficients). The content validity of the questionnaire was examined by literature review, interviews with patients, and experts' judgement. The construct validity was estimated by the methods of known groups, correlations between scales, and correlations with the SF-36 health survey. The success of the grouping or scaling of the questionnaire was estimated by examining the item (i.e. question) internal consistency and item (i.e. question) discriminant validity. Results The TCM questionnaire scales corresponded to the "eight principal syndromes", "ten questions", and "eight patterns of OA" within TCM concepts and frameworks. Internal consistency reliability (Cronbach's alpha) was above .70 for all scales on both occasions of the first test and the second test. Test-retest reliability (intra-class correlation coefficient) for each scale was also above .70 for all scales, except the exterior (EXT) scale, which was .44. Moderate associations were found between the age of subjects and the scores of the interior (INT) scale and summary (SUM) scale. There was a significant difference between the groups of use and non-use of on-going medication in the EXT scale scores on the first test, p = .012. However, this significant difference was not found on the second test. As expected, strong or moderate associations were found between the TCM questionnaire and SF-36 comparable scales. Conclusions The TCM questionnaire was developed within TCM concepts and frameworks. The questionnaire contains 23 items with two main scales (the EXT scale and the INT scale) and one additional scale (the SUM scale). It takes approximately five minutes to complete and is entirely self-administered. Results from this pilot study indicate that this TCM questionnaire might have adequate reliability and validity. Therefore, the questionnaire has potential usage as an outcome measurement instrument for the assessment of TCM in the patients with OA of the hip or knee. For this application to be possible, the questionnaire needs further development and validation with a larger sample of patients who have a variety of OA conditions.
