This experimental study was designed to investigate the inhibitory effects of ethanol extract of modified Yukgunja-tang(mYGJT) on high-fat diet-induced obesity and hyperlipidemia in Sprague-Dawley rats, Animals were divided into normal, control, mYGJT(100 mg/kg and 200 mg/kg) treated groups. Obesity with hyperlipidemia was induced by high fat diet treatment for 6 weeks. mYGJT was given to the amimals by oral gavage for 4 weeks, starting at the high-fat diet regimen, The effect of mYGJT on the differentiation of 3T3 L1 adipocytes in vitro and serological paramamters for obesity and hyperlipidemia in vivo were evaluated, mYGJT significnatly inhibited the differentiation of 3T3 L1 adipocytes in a concentration dependent manner. mYGJT treatment siginficantly reduced body weight, abdominal and epididymal fat weight, and FER(Food Efficiency Ratio) compared with control group in a dose dependent manner. It also signficantly inhibited the levels of serum total lipid, triglyceride, phospholipid, total cholesterol, LDL, AI(Atherosclerosis Index) and returned the serum HDL to normal. Total lipids, triglycerides and cholesterols in the liver, as well as malondialdehyde(MDA) and hydroxy radical in the serum were significantly reduced. However, superoxide dismutase(SOD) activity was significantly increased in mYGJT treated group compared with control group. Finally, mYGJT treatment signficantly decreased the MDA and protein carbonyl concentrations of the hepatic homogenate but signficantly increased the activities of SOD, GSH-Px and Catalase. Taken together, these results suggest that mYGJT can be clinically useful in inhibiting high-fat diet-induced obesity and hyperlipidemia.

This study investigated the clinical effect of Korean medicine treatments on two patients who experienced gastrointestinal symptoms with anxiety disorder. The patients were treated with herbal medicine (Yukgunja-tang, Banhabakchulchunma-tang) and acupuncture for 11 days and 26 days, respectively. The Beck Anxiety Inventory (BAI) and Gastrointestinal Symptom Rating Scale (GSRS) scores on the day of hospital admission and after treatment were compared; both the BAI and GSRS scores decreased after treatment. Moreover, the grade of the gastrointestinal symptoms changed from severe to mild or none. Therefore, these cases are useful for describing Korean medicine treatments for anxiety disorders in patients who experience gastrointestinal symptoms. However, additional case reports and studies are be needed in the future to confirm these findings.

It is necessary to investigate the efficacy of commercial Korean herbal medicine for cognitive disorder. The purpose of this study is to select candidates among licensed herbal medicines that are expected to be effective in the treatment of cognitive disorders and can be used in future clinical trial. From laboratory experiments, we first found individual single herbal drugs that could be effective for cognitive disorder, and then through experts recommendation, selected five priorities of single herbal drug and obtained the information of the best herb as a combination of each herbal drug. To derive the final herbal prescriptions, we searched the KFDA drug information system for licensed herbal medicines containing each drug and its combination. As a result of laboratory experiments and experts recommendation, we found that the five effective single herbal drugs for cognitive disorders. They are Ginseng Radix, Acori Graminei Rhizoma, Cyperi Rhizoma, Coptidis Rhizoma, Pinelliae Rhizoma, Hoelen cum Pini Radix, and Rehmanniae Radix Preparata(Pinelliae Rhizoma, Hoelen cum Pini Radix, and Rehmanniae Radix Preparata were tied for $5^{th}$). And licensed herbal prescriptions derived from the planned search are Palbohoichoon-tang, Taehwa-hwan, Bosim-hwan, and so on. Among these, in consideration of the feasibility of research and possibility of success in development, Yukgunja-tang, Samhwangjichul-hwan can be selected as future study subjects. Through experimental studies and expert recommendations, we have derived herbal prescriptions that can be effective in treating cognitive disorders from licensed herbal medicines.
