As proved from experiments, the application has the advantages that the fatty livers due to high fat and high cholesterol can be obviously reversed by the aid of the medicine compositions, and the liver fibrosis and the liver injury due to combination effects of the high fat, the high cholesterol and streptozotocin irritation can be obviously reversed.

The present invention relates to the use of serotonergic compounds for the treatment of virus-induced thrombocytopenia. More particularly, the invention relates to methods of treating thrombocytopenia by blocking serotonin activity. For example, inhibitors of receptor 5HT2A and/or receptor 5HT1A and/or inhibitors of mast cell degranulation and/or inhibitors of serotonin uptake may be used. Preferably, the thrombocytopenia is induced by dengue or Japanese Encephalitis virus, and the inhibitors are preferably ketanserin, WAY-100135, sarpogrelate, or fluoxetine.

The invention aims to disclose sarpogrelate hydrochloride prepared by a convenient and environment-friendly method, relates to a solvent, in particular to a solvent which is prepared by free condensation of 2-[2-(3-methoxyphenyl) ethyl] phenol and epoxy chloropropane (2-[2-(3-metoxypherol) ethyl] pherol withepoxychloropropane). Under atmospheric pressure, dimethylamine is used for ring opening ofethylene oxide of the obtained intermediate, and then the intermediate reacts with succinic anhydride to obtain sarpogrelate. The obtained free alkali is treated by using isopropanol IPA.HCl to obtainthe sarpogrelate hydrochloride. Crystals of hydrochloride are formed in acetone, and a pure product is obtained. According to the preparation method, solvent-free reaction is adopted in the first step, atmospheric pressure reaction is adopted in the second step, and thus the preparation method is suitable for industrial production.
