Drug therapy with steroids and moisturizers is highly effective for the treatment of atopic dermatitis, but the use of steroids is dependent on the stage of the patient’s disease. Shiunkou is a Kampo topical ointment with a purple tinge called shicon. It has been reported to be used clinically in combination with a moisturizer; however its stability has not been described. In this study, we investigated the stability of Shiunkou and Hirudoid Soft Ointment when mixed. The simplest method for measuring stability is to observe changes in appearance. The mixed ointment did not change during refrigerated storage for up to 7 months. When stored at room temperature, oil separation occurred after the first month, and became more remarkable with time, such as at 3 months and 7 months. It has been shown that the ointment mixture should be stored refrigerated rather than stored at room temperature. When the stability of shicon, which is an active ingredient of Shiunkou, was examined in an aqueous solution, it decomposed very quickly regardless of the pH. Hirudoid Soft Ointment is a w/o preparation and contains water. When the ointment is mixed, and shicon, a the component of Shiunkou, comes into contact with the water contained in the Hirudoid Soft Ointment, there is a concern that the content of shicon in the ointment mixture may decrease, even if by a small amount or for a short time.

桂皮の血流改善作用については古くから知られており,これに関連した報告はあるものの,その詳細な検討はなされていない。今回我々はマグヌス法を用いて,ラット胸部大動脈輪状標本における桂皮含有クンニンの血管作動性について検討した。桂皮含有タンニンは,プロスタグランディンF_<2α>(PGF_<2α>)の血管収縮に対し,内皮保存血管において濃度依存性に血管弛緩作用が認められた。しかし,内皮除去血管及ぴN^G-nitro-l-argininemethyl ester(L-NAME)前処置内皮保存血管においては,血管弛緩作用はほぼ消失した。以上より,桂皮含有タンニンの血管弛緩作用は内皮依存性であることが明らかとなった。桂皮含有タンニンをさらに二量体から五量体までのタンニン画分に分取し検討したところ,二量体以上の重合したタンニンにおいて血管弛緩作用が認められた。また,重合度が増すに従い血管弛緩作用はより低い濃度で発揮され,作用も増強されることが明らかとなった。

By screening water and MeOH extracts of 30 Chinese medicinal plants for their anti-herpes simplex virus (HSV)-1 activity, a MeOH extract of the root tubers of Stephania cepharantha HAYATA showed the most potent activity on the plaque reduction assay with an IC_<50> value of 18.0 μg/ml. Of 49 alkaloids isolated from the MeOH extract, 17 alkaloids were found to be active against HSV-1,including 13 bisbenzylisoquinoline, 1 protoberberine, 2 morphinane and 1 proaporphine alkaloids, while benzylisoquinoline and hasubanane alkaloids were inactive. Although N-methylcrotsparine was active against HSV-1,as well as HSV-1 thymidine kinase deficient (acyclovir resistant type, HSV-1 TK^-)and HSV-2 (IC_<50> values of 8.3,7.7 and 6.7 μg/ml, respectively), it was cytotoxic. FK-3000 was found to be the most active against HSV-1,HSV-1 TK^- and HSV-2 (IC_<50> values of 7.8,9.9 and 8.7 μg/ml) with in vitro therapeutic indices of 90,71 and 81,respectively. FK-3000 was found to be a promising candidate as an anti-HSV agent against HSV-1,acyclovir (ACV) resistant-type HSV-1 and HSV-2.

Three new lanostante-type triterpene aldehydes, named lucialdehydes A-C (1-3), were isolated from the fruiting bodies of Ganoderma lucidum, together with ganodermanonol (4), ganodermadiol (5), ganodermanondiol (6), ganodermanontriol (7), ganoderic acid A (8), ganoderic acid B8 (9), and ganoderic acid C1 (10). The structures of the new triterpenes were determined as (24E)-3β-hydroxy-5α-lanosta-7,9(11),24-trien-26-al (1), (24E)-3,7-dioxo-5α-lanosta-8,24-dien-26-al (2), and (24E)-3β-hydroxy-7-oxo-5α-lanosta-8,24-dien-26-al (3), respectively, by spectroscopic means. The cytotoxicity of the compounds isolated from the ganoderma mushroom was tested in vitro against Lewis lung carcinoma (LLC), T-47D, Sarcoma 180, and Meth-A tumor cell lines. Lucialdehydes B, C (2, 3), ganodermanonol (4) and ganodermanondiol (6) showed cytotoxic effects on tested tumor cells. Of the compounds, lucialdehyde C (3) exhibited the most potent cytotoxicity against LLC, T-47D, Sarcoma 180, and Meth-A tumor cells with ED_<50> values of 10.7, 4.7, 7.1, and 3.8 /μg/ml, respectively.
