Cannabis sativa is a plant widely cultivated worldwide and has been used as a material for food, medicine, building materials and cosmetics. In this study, we assessed the functional effects of C. sativa stem and root extracts using network pharmacology and confirmed their novel functions. The components in stem and root ethanol extracts were identified by gas chromatography-mass spectrometry analysis, and networks between the components and proteins were constructed using the STICHI database. Functional annotation of the proteins was performed using the KEGG pathway. The effects of the extracts were confirmed in lysophosphatidylcholine-induced THP-1 cells using real-time PCR. A total of 21 and 32 components were identified in stem and root extracts, respectively, and 147 and 184 proteins were linked to stem and root components, respectively. KEGG pathway analysis showed that 69 pathways, including the MAPK signaling pathway, were commonly affected by the extracts. Further investigation using pathway networks revealed that terpenoid backbone biosynthesis was likely affected by the extracts, and the expression of the MVK and MVD genes, key proteins in terpenoid backbone biosynthesis, was decreased in LPC-induced THP-1 cells. Therefore, this study determined the diverse function of C. sativa extracts, providing information for predicting and researching the effects of C. sativa.

Storage material of endosperm cells digested by various enzymes should be transported to the embryo. At this time, the cellulose of the endosperm cell wall is guessed to be hydrolyzed by the cellulase enabling to transfer the storage material from the endosperm cells to the embryo. Therefore, this study has been carried out to investigate the ultrastructure of endosperm and the localization of the cellase activity on Cannabis sativa L. during germination. Endosperm cells contain a large number of lipid bodies and protein bodies with globoids as the storage material. During gemination they are gradually degenerated, however, the former almost remain until the cells are completely digested. Electron-microscopical reaction products of cellulase on endosperm cells are present. The closer the embryo, the more amount of reaction products on the endosperm cell wall are appeared.

We prepared densified wood pellet by agricultural waste. The hemp woody core was used as replacing wood resource. Hemp was separated into the bast fiber and the woody core by hot steaming treatment. The hemp woody core had a similar lignin content(19.4%) and carbohydrate composition with hardwood(20-25% lignin in hardwood), respectively. Also, the hemp had a low ash content(0.5%), which resulted in a low ash formation in pellet burning. Heating value of the hemp pellet(18.40 MJ/kg) had a very similar to the pellet made by hardwoods. The hemp woody core could be replaced the hardwood for densified wood pellet.

To detect the toxic relevant components, asarone, coumarin and thujone, in the 87 medicinal plants used in brewing a Korean traditional folk wine, their 20% ethanol extracts were prepared and purified by a SPE(solid phase extraction) method. The toxic components in the purified extracts were identified by GC-FID and GC/MS analysis. On analyses, asarone was detected in 6 species, Acorus gramineus Solander, Acorus asiaticus Nakai, Angelia gigus Nakai, Santalum album, etc.; coumarin in 22 species, Anethum graveolens, Foeniculum vulgare Gaertner, Lithosperum erythrorhizon Siebold et Zuccarinii, etc.; thujone in 24 species, Achyranthes japonica Nakai, Amomum xanthiodes Wallich, Artemisia asiatia Nakai, seed of Cannabis sativa L., Caragana sinica R., Chrysanthemum morifolium Ramat, Codonopsis lanceolata Bentham et flooker, Foeniculum vulgare Gaertner, etc.

This study was performed to investigate concept, systoms, causes of disease, pathogenic mechanisms, therapies and precriptions about senile constipation through the successive medical literature, recent chinese medical literature and chinese medical joumals. Senile constipation seems to be applicable to dryness syndrom and constipation of insufficiency type, have something to do with kidney(the most), lung, spleen and large intestine. The most principal cause of disease is yin-fluid, the rest deficiency of qi, insufficiency of yang, stagnation of qi and retention of fever etc. There are enriching the blood and moistening dryness in principal therapy, the rest are invigorating qi and loosing the bowel, warming and invigorating the spleen and kidney, regulating the flow of qi and promoting the stagnancy of qi and expelling the pathogenic heat etc. In prescriptions there are Yunjangtang, Jengaektang, Hwanggitang, Jechunjeon, Yukmatang and Majainhwan as the causes of disease, meanwhile are Yungjang-tang, Jechunjeon and Majainhwan in the vulgaris prescriptions. And in medical herbs there are nourishing yin medicines as Rhizoma rehmanniac, Radix ophiopogonis and Radix scrophulariae etc., invigorating qi medicines as Radix astragali, Radix codonopsitis and Radix polygoni multiflori etc, invigorating yang medicines as Caulis cistanchis and Semen psoraleae etc., promoting qi circulating medicines as Radix saussurea, Lignum aquilariae and Radix linderae etc., and reducing fever and therapeutic method to keep the adverse qi flowing downward medicines as Semen cannabis, Rhizoma rhei, Fructus immaturus ponciri, and Cortex magnoliae etc.. Meantime Rhizoma rehmanniae, Radix ophiopogonis, Caulis cistanchis, Radix angelicae gigantis, Semen cannabis, Semen biotae, Semen pruni japonicae and Semen persicae in principal herb-medicines. In clinical reports the process of disease was between 10 to 20 years, the evacuation cycle between 4 to 7 days, generally possessed chronic diseases as hypertension, diabetes, arteriosclerosis and cerebro- vascular disorders etc. and the efficiency rate was more than 90%. The senile constipation is occured in succession or promoted by chronic diseases as obesity, hypertension, diabetes, arteriosclerosis. hrperlipemia, cerebro- vascular disorders etc., so diet-regulating, adequate exercise, proper evacuation-habit and psychologic rest etc. are important more than medicine-treatments.

Objectives : The purpose of this study is to investigate splenic constipation syndrome(脾約證) in Shanghanlun by comparing 179 & 247 provisions. Methods : Including Shanghanlun, several texts which contain Cheng Wu-ji, Wan Mi-zhai, Qian Huang, Zhu Gong, Fang You-zhi, Yu Jia-yan, Zhang Lu, Cheng Ying-mao, Zhang Xi-ju, Chen Xiu-yuan, Wu Qian, Xu Ling-tai, You Zai-jing, Zhu Dan-xi's opinion about the splenic constipation syndrome were chosen and comparative consideration was carried out. Results & Conclusions : The following conclusions could be drawn. 247 provisions in Shanghanlun is different from 179 provisions because the beginning of the each splenic constipation syndrome is different. The difference between 179 & 247 provisions are proved by comparing Mild Purgative Decoction which is used Taiyangyangming splenic constipation syndrome and Fructus Cannabis Pill which is used Dorsal pedal pulse splenic constipation syndrome. Cheng Wu-ji's opinion that 179 & 247 provisions is different is meaningful because he is first investigated the different beginning of the splenic constipation syndrome. Several annotator's opinion which oppose Cheng Wu-ji is majority and they set a high value on Jangbu(臟腑) factor. Several annotator's opinion which agree Cheng Wu-ji is minority and they set a high value on splenic constipation syndrome also begins from Taiyangbing. The concept of overlapping of Taiyangyangming is different from the concept of Taiyangyangming. Consequently 179 & 247 provisions has to be distinguished.

Hemp (Cannabis sativa L.) is a dioecious plant, although monoecious plants are bred in some cultivars for fiber or seed production. Recently, hemp has received attention for medicinal use with some cannabinoids, including cannabidiol. Self-fertilization for breeding inbred lines is difficult because of dioeciousness and anemophily in hemp. This experiment was conducted to develop a self-fertilization method by forming female flowers and seeds from male plants of dioecious hemp. To induce the formation of female flowers on male plants, 500 mg L^-1 of ethephon was sprayed on plants at soon, seven and fourteen days after primordia formation. The plant ratio of female flowers formation and the number of harvested seeds were increased by ethephon treatment. Female flowers of male plants have 5 stigmas in contrast to the dual stigma of female 1plants. Male plant seeds were lighter and smaller than those from female plants. Although the germination rate was lower than that of normal seeds from female plants, the seeds from male plants germinated to grow seedlings. Thus, we suggest that hemp plants should be treated with ethephon at soon after primordia formation to induce the formation of more female flowers on the male plants.
