In the present study, we investigated the effects of Er-Zhi-Wan（EZW） on the microarchitecture and the regulation of Wnt/β-catenin signaling pathway in the alveolar bone of ovariectomized rats. Thirty Sprague-Dawley rats were randomly divided into three groups： sham operation group（sham, n=10）, ovariectomy（OVX） group（n=10）, and OVX with EZW treatment group（EZW group, n=10）. From one week after ovariectomy, EZW（100 mg/mL） or vehicle（distilled water） was fed（1 mL/100 g） once per day for 12 weeks until the sacrifice of the rats. The body weights were measured weekly. After sacrifice, the sera and mandible were collected and routinely prepared for the measurement of alveolar trabecular microarchitecture, serum levels of E2, bone-specific alkaline phosphatase（BALP） and tartrate-resistant acid phosphatase 5b（TRAP5b）, as well as mandibular mRNA expression of Wnt/β-catenin signaling pathway molecules wnt3a, low-density lipoprotein receptor-related protein 5（LRP5）, β-catenin and dickkopf homolog 1（DKK1）. The results showed that EZW treatment significantly prevented the body weight gain, degradation of alveolar trabecular microarchitecture and alveolar bone loss in the OVX rats. Furthermore, we observed that EZW could increase the serum levels of E2 and BALP, and decrease levels of serum TRAP5b in EZW group compared with vehicle group. In addition, RT-PCR results revealed that EZW upregulated the expression levels of wnt3a, LRP5 and β-catenin, and reduced the expression of DKK1 in OVX rats. Taken together, our results suggested that EZW may have potential anti-osteoporotic effects on osteoporotic alveolar bone by stimulating Wnt/LRP5/β-catenin signaling pathway.展开更多

Under the optimum conditions, excellent separation was achieved, and the assay was fully validated in terms of linearity, precision, repeatability, stability and accuracy. The validated method was applied successfully to the determination of the five compounds in SJZTC samples from different production batches. The HPLC method can be used as a valid analytical method to evaluate the intrinsic quality of SJZTC.展开更多

Hypocotyl slices were cultured on Murashige and Skoog （MS） and B5 basal medium supplemented with varied concentration of different plant growth-regulators, e.g., α-naphthaleneacetic acid （NAA） and indole-3-butyric acid （IBA） in combination with 6-benzylaminopurine （6-BA） and kinetin. The study showed that shoots could be directly regenerated from hypocotyl explants without the intervening callus phase; MS medium was more suitable for adventitious shoots regeneration. The ability of hypocotyls segments to produce shoots varied depending upon their position on the seedlings. The highest regeneration rate was obtained with hypocotyl segments near to the cotyledon cultured on MS basal medium supplemented with 1.5 mg L^-1 6-BA and 0.05 mg L^-1 NAA （63.64%）. The regenerated shoots were readily elongated on the same medium as used for multiplication and rooted on half-strength MS basal medium supplemented with 1.0 mg L^-1 IBA and 100 mg L^-1 activated carbon. After being transferred to greenhouse conditions, 96% of the plantlets were successfully acclimatized. This regeneration system is applied for genetic transformation now.展开更多

Methods Ethanol extracts obtained from two kind of Chinese medicinable herbs were tested. Human melanocytes were obtained from neonatal foreskins and 48-well culture dish covered with fibronectin were used to perform melanocyte adhesion assay; Motility was assessed using the micropore filter method. Results: The extracts of Bu Gu Zhi(Psoralea corylifolia L), Bai Zhi(Dahurian angelica root) obviously showed an effect in increasing of human melanocyte adhesion and migration on fibronectin. Conclusion It is suggested that Buguzhi(Fructus Psoraleae) and Baizhi(Radix Angelicae Dahuricae) might induce melanocyte adhesion and/or migration in the treatment of vitiligo.展开更多
