Objectives: Obesity is becoming more popular disease worldwide. Because of the side effects of conventional obesity treatment modality, herbal medicine treatment is becoming more preferred. Gambihwan which including Ephedra sinica Staph is widely used in traditional Korean Medicine practice for obesity treatment. Garcinia cambogia is a kind of health functional food that has body fat reducing effect. Nowadays, ephedra and Garcinia cambogia are often used simultaneously in clinical practice of Korean Medicine. However, the effectiveness and safety of combination therapy in obesity treatment is not well established. Methods: We conducted retrospective observational study to explore effectiveness and safety of combination therapy. We evaluated effect of combined treatment of Gambihwan and Garcinia cambogia on body weight, body mass index, body fat mass, and waist hip ratio reduction. We also assessed safety via liver function test and adverse event. Results: Finally, 23 patients were included. In paired t-test, body weight significantly decreased from 64.50±14.50 kg to 62.94±13.85 kg (P<0.001) and body mass index were also significantly decreased from 24.43±3.79 kg/㎡ to 23.83±3.59 kg/㎡ (P<0.001). Body fat mass was also reduced. Aspartate transaminase and alanine aminotransferase were not significantly increased. There were no drug-induced liver injury and no severe adverse event. Conclusions: In our retrospective review, we found combination therapy of Gambihwan and Garcinia cambogia reduce body weight, body mass index and body fat mass. There were no severe adverse event and drug induced liver injury which indicated safety of combination therapy in obesity treatment.

Objectives : Present study investigated the hepatoprotective effects of various combinations of lemon balm and dandelion (LD) leaf extract on carbon tetrachloride ($CCl_4$)-induced acute liver injury. Methods : Mice were orally treated with 200 mg/kg of LD extracts [1:1, 1:2, 1:4, 1:6, 1:8, 2:1, 4:1, 6:1, or 8:1 (weight : weight)] for 7 days, and then intraperitoneally injected with $CCl_4$ (0.5 mL/kg). Silymarin (100 mg/kg) was used as reference drug. Body weight gain, relative liver weight, serum biochemistry, histopathologic analyses, and hepatic antioxidant system were examined to elucidate the fittest combination ratio of LD extract. Results : All varying combinations of LD extract significantly increased body weight gain and decreased relative liver weight by $CCl_4$. In addition, LD extract reduced serum aspartate aminotransferase and alanine aminotransferase. Histopathological analyses indicated that LD extract significantly decreased histological activity index score, degenerated hepatocytes, and infiltrated inflammatory cells induced by $CCl_4$. Moreover, LD extract reduced lipid peroxidation, and attenuated the reduction of hepatic glutathione, superoxide dismutase, and catalase by $CCl_4$. Although there were no statistical differences in body weight gain between silymarin- and LD extract-treated groups, administration of 1:1, 2:1, and 4:1 combination of LD extract exhibited more favorable hepatoprotective effects than silymarin. Especially, 2:1 combination of LD extract showed the most potent hepatoprotective effects. Conclusion : Of various combinations of LD extract tested, present results suggest that 2:1 combination of LD extract would be a promising herbal formulation to protect liver from oxidative stress.

So far more than 350 drugs have been reported to be the cause for lung injury and the incidence tends to increase. Although infiltrative lung disease is the most common pattern of drug-induced lung injury, it can appear in the form of alveolar changes, vasculitis and other injury. Herbal medicine also has been known as a cause for interstitial pneumonitis, but it is difficult to identify the key herbal medicine because of the complex components of the contents. Till date, there is no report of pneumonitis caused by golden thread. Here we report a case of a 54-year-old male who developed interstitial pneumonitis with acute liver injury caused by herbal medicine made from golden thread.

Most inflammatory disorders are usually treated using anti-inflammatory drugs including non-steroidal anti-inflammatory drugs (NSAID) and steroidal anti-inflammatory drugs (SAID). Prolonged uses of NSAIDs and SAIDs may frequently cause adverse side-effects such as nausea, vomiting, diarrhea, constipation, decreased appetite, kidney and liver failure, ulcers, and prolonged bleeding after an injury or surgery. Thus, it is necessarily required to develop a new anti-inflammatory drug with little side-effects. Dandelion (Taraxacum officinale) possesses the therapeutic abilities to eliminate body heat and toxins and to remove swelling and inflammation. In order to verify the anti-inflammatory activity of dandelion, TPA(12-O-tetra decanoylphorbol-acetate)-induced or croton oil-induced acute edema was developed in the mouse ears, and dandelion extract dissolved in acetone was applied to both sides of inflamed ears. It was found that dandelion could significantly reduce the ear swelling, compared to that of non-treated control. In the case of $20{\mu}{\ell}$ application of $100mg/m{\ell}$ dandelion solution (DA-100), its anti-inflammatory effect was comparable to that of indomethacin, a non - steroidal anti-anflammatory drug. Taken together, it could be concluded that topically applied dandelion extract exhibited its potentials as a new drug candidate with an effective anti-inflammatory activity.

Cyclosporine(CsA) is an immunosupressant drug widely used in post-allogeneic organ transplant to reduce the activity of the patient's immune system and so the risk of organ rejection. It has been studied in transplants of skin, heart, kidney, liver, lung, pancreas, bone marrow and small intestine. Initially isolated from a Norwegian soil sample, Both kidney and liver dysfunction are prominent side effects of CsA. The present study was designed to determine the possible protective effect of salidroside(Sal) isolated from the BuOH extract of Acer termentosum Max against oxidative damage in CsA-treated(50 mg/kg, ip) nephrotoxicity rats. Results showed oral administration of methanol and butanol extact of Acer termentosum Max(200 mg/kg, po) significantly reduced activities of marker enzymes(BUN, Creatinine) and LDH activity in serum to CsA induced experimental kidney injured rats. And significantly decrcease of protein amount level in urine and activities of free radical formation enzyme were significantly improved by the treatment of Sal. And significantly decrcease of MDA level in kidney and activities of calalase, glutathione peroxidation and SOD were significantly improved by the treatment of Sal(20 mg/kg, po). But glutathione concentration and glutathione S-transferase actitity was not affected. Results of this study revealed that Sal could afford a significant protection in the alleviation of CsA-induced nephrotoxicity injury.

The aim of this study was to investigate the safety of short-term use of Korean herbal medicine (KHM; prescribed herbal medicine by doctors of traditional Korean medicine) on liver function. Three hundred eighty four outpatients who took KHM for various conditions were enrolled for multi-center, prospective observational study. Of them 237 patients completed questionnaire and were checked liver function (aspartic aminotransferase;AST, alanine aminotransferase;ALT, alkaline phosphatase;ALP, total bilirubin;t-Bil, direct bilirubin;d-Bil, gamma glutamyltranspeptidase;GGT, protein and albumin) before and after taking KHM (duration; 21.4${\pm}$10.0 days), and data were analysed statistically. Of the 213 patients showing normal liver function test (LFT) at baseline, 209 (98.1%) remained within the normal range at the second test while 3 (1.4%) revealed slight increase of LFT. Only one subject had raised LFT regarding level of liver injury without perceived symptoms. Twenty-four of 237 patients were abnormal at baseline, and 16 at the second testing. Of the patients taking KHM, only 4 changed from normal to abnormal while 12 from abnormal to normal in their LFT. There were no significant increase in LFT level between the first and second test, except in the t-Bil level, however, the change of t-Bil was small and within normal range. The current study showed that the use of KHM did not increase the frequency of abnormal LFTs, at least in the short term.

This study was performed to investigate the effect of the extracts from Injinoryng-San on liver injury patients induced by alcohol. Injinoryung-San was recorded the drug for jaundice at Hwang-Je-Nae-Kyung. Twenty-seven patients who have intaked alcohol above 40 g, every day, 5 years, twenty-seventy ages were selected. After take a written consent, we divide them into experimental groups and control groups by double blind test. Each groups was evaluated every 2 weeks(2,4,6 weeks). After 2 weeks, Injinoryung-San groups significantly decreased GGT in comparison with control groups(p<0.05). After 4 weeks, Injinoryung-San groups significantly decreased MCV, GGT in comparison with control groups(p<0,05). After 6 weeks, Injinoryung-San groups significantly decreased MCV in comparison with control groups(p<0.05). Reviewing these experimental results, it appears that extracts of Injinoryung-San have pharmaceutical efficacy in GGT, MCV on liver injury patients induced by alcohol. But it has not efficacy in AST, ALT. According to drinking alcohol has becomes social problems, we should effort to make efficacious oriental medicines on alcoholic hepatitis.

It has been hypothesized that formation of oxygen-derived free radicals may play an important part in ischemically induced tissue injury. In this study, the effects of vitamin C treatment on hepatic reperfusion model were investigated. Livers isolated from 18 hrs fasted rats were subjected to low flow hypoxia (1 $m\ell$/g liver/min, for 45min) followed by reoxygenation (for 30min). The perfusion medium used was Krebs-Henseleit bicarbonate buffer (KHBB, pH 7.4) and vitamin C (0.25, 0.5, 1.0 and 2.0 mM) was added to perfusate. 7-Ethoxycoumarin was used as substrate of phase and metbolism. After hypoxia oxygen consumption significantly dropped but vitamin C 0.25, 0.5 and 1.0 mM treatments restored oxygen consumption to the level of control group. LDH and lipid peroxidation were not changed in all experimental groups. Oxidation, phase metabolism, significantly decreased following hypoxia but improved during reoxygenation. Vitamin C 0.25 mM treatment significantly improved the oxidation of 7-ethoxycoumarin during hypoxia and reoxygenation, but the oxidation significantly decreased by vitamin C 2.0 mM treatment. Similarly, sulfate conjugation decreased in hypoxic group, but this decrease was inhibited by vitamin C 0.25, 0.5 and 1.0 mM treatments. Our findings suggest that hypoxia/reoxygenation diminishes hepatic drug metabolizing function, vitamin C at concentration of 0.25-1.0 mM ameliorates but at higher concentration aggravates these hypoxia/reoxygenation-induced changes.

This study aims to develop new potential therapeutic moracin M prodrugs acting on lung inflammatory disorders. Potential moracin M prodrugs (KW01-KW07) were chemically synthesized to obtain potent orally active derivatives, and their pharmacological activities against lung inflammation were, for the first time, examined in vivo using lipopolysaccharide (LPS)-induced acute lung injury model. In addition, the metabolism of KW02 was also investigated using microsomal stability test and pharmacokinetic study in rats. When orally administered, some of these compounds (30 mg/kg) showed higher inhibitory action against LPS-induced lung inflammation in mice compared to moracin M. Of them, 2-(3,5-bis((dimethylcarbamoyl)oxy)phenyl)benzofuran-6-yl acetate (KW02) showed potent and dose-dependent inhibitory effect on the same animal model of lung inflammation at 1, 3, and 10 mg/kg. This compound at 10 mg/kg also significantly reduced IL-1β concentration in the bronchoalveolar lavage fluid of the inflamed-lungs. KW02 was rapidly metabolized to 5-(6-hydroxybenzofuran-2-yl)-1,3-phenylene bis(dimethylcarbamate) (KW06) and moracin M when it was incubated with rat serum and liver microsome as expected. When KW02 was administered to rats via intravenous or oral route, KW06 was detected in the serum as a metabolite. Thus, it is concluded that KW02 has potent inhibitory action against LPS-induced lung inflammation. It could behave as a potential prodrug of moracin M to effectively treat lung inflammatory disorders.

This study was carried out to compare the histopathological differences of liver lesions in carbon tetrachloride ($CCI_4$), dimethylnitrosamine (DMN), thioacetamide (TAA) and bile duct ligation (BDL)-induced rats. $CCl_4$, DMN and TAA were administered intraperitoneally and conducted bile duct ligation for 4 weeks to induce hepatic fibrosis. Indices of liver cell injury (steatosis, hydropic degeneration, bile duct hyperplasia, hemorrhage & hemosiderin deposition), the extent of liver fibrosis (fibrotic area) and the rate of regeneration (number of PCNA-positive cells) were investigated in each group. Liver tissues were stained with hematoxylin-eosin (HE), sirius red, prussian blue and immunostained with ${\alpha}$-smooth muscle actin (${\alpha}$-SMA), transforming growth factor-${\beta}1$ (TGF-${\beta}1$), proliferative cell nuclear antigen (PCNA), and quantified using a computerized image analysis system. Liver cell steatosis was significantly increased in $CCl_4$ and TAA groups, and hydropic degeneration and bile duct hyperplasia were significantly increased in TAA and BDL groups when compared with that in normal control, respectively. Fibrosis area was significantly increased in all four groups, especially in $CCl_4$ group. Correlation between ${\alpha}$-SMA and TGF-${\beta}1$ expressions in four groups was good. Hemorrhage area in liver parenchyma was significantly increased in DMN group only when compared with that in normal control, while hemosiderin deposition area was significantly increased in TAA and BDL groups as well as DMN group. The Number of PCNA-positive cells was significantly increased in all four groups, especially in TAA group. These results indicate that the duration and methods of hepatotoxic drug treatment are very important factors to make plans for animal experimentation on the induction of hepatic fibrogenesis in rats.
