The book included a large amount of medical literature, introducing medical customs and the production of drugs in various places, as well as the efficacy of some medicine. These materials are of unique value for understanding the medicine trade in the Song dynasty, and even the medical culture along the “Maritime Road of Aromatic Medicine”.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

[Methods] According to the method described in Chinese Veterinary Pharmacopoeia,thin layer chromatography was used for qualitative identification of forsythin contained in Jin Weng Zhi Li Granule by improving the developing conditions. [Results]After optimizing TLC conditions of Jin Weng Zhi Li Granule,that is,the thin layer plate was pre-equilibrated in the expansion cylinder for 5 min after spotting,the separation effect of TLC of test samples was favorable. The spot color was clear,reproducibility was good,precision was high,specificity was better. [Conclusions]The method is of good feasibility,reproducibility and specificity,and could be used for qualitative detection of forsythin contained in Jin Weng Zhi Li Granule.展开更多
