Semisulospira libertine (SL) has been used as a folk medicine for quenching a thirst, hepatic fever and inflammation in oriental countries. Although SL has been anecdotally ascertained to ameliorate the hepatic diseases, there are no sufficient experimental evidences. The purpose of this study was to examine the effect of Bitam-S, in which SL is a main component, on non-alcoholic fatty liver disease manifested in C57BL/6J ob/ob mice. At 6 week old, the ob/ob mice were randomly divided into four groups; control and three treatment groups. The control mice was to receive a regular diet, and the treatment groups were fed a regular diet with either 250mg/kg, 500mg/kg of Bitam-S (BS250 and BS500) or 300mg/kg of metformin (MT300) for a 8-week period. Bitam-S exerted beneficial effects on lipid homeostasis in ob/ob mice that are not necessarily due to its ability to decrease food intake but its specific effects on hepatic lipogenesis related genes (SREBP1a, FAS and SCD-1). The combined effects of Bitam-S to reduce body weight and lipogenic gene expressions, and reduce the deposition of triglyceride in the liver are indicative of a marked improvement in obesity-related non-alcoholic fatty liver disease. Taken together, Bitam-S has potential as a treatment agent for non-alcoholic fatty liver disease and deserves clinical trial in the near future.

Gastroesophageal reflux disease (GERD) is a common disorder caused by the reflux of gastric contents into the esophagus. According to the recent classification, GERD can elicit esophageal and extraesophageal syndromes. Laryngopharyngeal reflux (LPR) is defined as laryngeal symptoms with laryngeal inflammation caused by the acid reflux. The prevalence of GERD and LPR is increasing during the past decades in Korea and management of GERD and LPR is a challenging issue in clinical practice. Proton pump inhibitor is the most effective drug in the treatment of GERD. Most patients with LPR are given a 2-month trial of a proton pump inhibitor (PPI), however, there is still little evidence on the diagnosis or the treatment of LPR. During the last years concern have been raised regarding the risk of averse events related to long-term use of PPI. We review the recent update on medical treatment of GERD/LPR.

Polygonum cuspidatum has been used as treatments of dermatitis, gonorrhea, inflammation, and hyperlipidaemia in traditional medicine. We examined liver protective effect on CCl$_4$ inducing hepatotoxicity and anti-oxidative activity by TBA method. Phytochemical examination of Polygonum cuspidatum led to the isolation and characterization of emodin 8-O-${\beta}$-D-glucopyranoside (compound 1), and trans-resveratrol 3-O-${\beta}$-D-glucopyranoside (compound 2). Compounds 1 and 2 enhanced the inhibition of anti-lipid peroxidative effects in liver homogenate. In chemical parameters obtained from serum analysis, compounds 1 and 2 also revealed significant decrease in hepatotoxicity. These results suggested that the antraquinone and stilbene which were isolated from Polygonum cuspidatum might be used as therapeutic agent of hepatitis.

The Tolosa-Hunt syndrome is a symptom complex with unilateral painful ophthalmoplegia associated with retro-orbital pain, proptosis and Ⅲ, Ⅳ, Ⅴ-1, Ⅵ cranial nerves palsy due to nonspecific granulomatous inflammation in the superior orbital fissure or cavernous sinus. We experienced a 50 years old female patient with Tolosa-Hunt syndrome who had several clinical signs and symptoms such as ocular pain, headache, sensory loss of face, diplopia, and visual disturbance. In the point of Differentiation of Syndrome(辨證). this subject was diagnosed as Deficiency of yin in liver and kidney(肝腎陰虛), and was administrated with Yangyeummyungmoktang-Gamibang. After treatment of acupuncture and herbal medicine above symptoms were improved.

In the present study, we investigate the role of V. vulnificus in promoting the inflammation of mouse ileal ephitelium and its related signaling pathways. ICR mice were infected orally with V. vulnificus ($1{\times}10^9CFU$) for 16 h as a representative model of food-borne infection. To find the major portal of entry of V. vulnificus in mouse intestine, we have measured the levels of bacterial colonization in small intestine, colon, spleen, and liver. V. vulnificus appeared to colonize in intestine and colon in the order of ileum >> jejunum> colon, but lack in the duodenum, spleen, and liver. V. vulnificus in ileum caused severe necrotizing enteritis and showed shortened villi heights accompanied by an expanded width and inflammation, compared with the control mice. V. vulnificus induced ileal epithelium inflammation by activating phosphorylation of PKC and membrane translocation of $PKC{\alpha}$. V. vulnificus induced the phosphorylation of ERK and JNK, but did not affect p38 MAPK phosphorylation. Notably, V. vulnificus stimulated the I-${\kappa}B$-dependent phosphorylation of NF-${\kappa}B$ in mouse ileal epithelium. Finally, the ileal infection of V. vulnificus resulted in a significant increase in expression of proinflammatory cytokines and Toll-like receptors, respectively, compared to the control. Collectively, our results indicate that V. vulnificus induces ileal epithelium inflammation by increasing NF-${\kappa}B$ phosphorylation via activation of PKC, ERK, and JNK, which is critical for host defense mechanism in food-borne infection by V. vulnificus.

The root of Polygonum cuspidatum (Polygonaceae) has been used as treatments of hyperlipidemia, dermatitis, gonorrhea, favus athlete's foot, inflammation in traditional medicine. In order to examine anti-lipidperoxidation activity, hexane, EtOAc, BuOH and water fractions of its methanol extract were administered to carbon tetrachloride intoxicated rats. Ethylacetate fraction exhibited antilipidperoxidative effect on liver lipid homogenate and the radical scavenging effect on DPPH. Serum transaminase, AlP, triglyceride and total cholesterol contents significantly decreased by administrations of ethylacetate fraction.

Synthesis and distribution of extracellular matrix (ECM) components are dynamically altered in response to the pathophysiological processes including infection, inflammation and apoptosis. In particular, the levels of hyaluronan (HA) change with concomitant increases in the levels of collagen (e.g. type I collagen) and fibronectin in chronic liver diseases.(omitted)
