The rhizome of Alisma orientale Juzep (Alismataceae) has been used as a crude drug for diabetes, edema, inflammation and urinary disturbances in oriental medicine. Recent animal studies have shown that the extract of Alisma orientale rhizome (AOR) can potently lower high levels of serum lipids and improve insulin resistance, which are usually detected in patients and animals with non-alcoholic fatty liver disease. So, we studied the antioxidative effects of AOR extracts and fraction in vitro and their protective effects against acute hepatotoxicity induced by $CCl_4$ in vivo.. We then investigated the effects of each fraction on hepatotoxicity induced by tert-butyl hydroperoxide (t-BHP). DAOR (dichloromethane fraction of the Alisma orientale rhizome) scavenged free radicals and superoxide anions. DAOR protected against $CCl_4$ induced hepatotoxicity. DAOR had hepatoprotective and antioxidative effects against t-BHP-induced hepatotoxicity in HepG2 cells and in rats.

Fish oil and shortening have been suggested to have opposite effects on cardiovascular disease (CVD). This study investigated the effect of shortening and fish oil on CVD risk factors and aorta histopathology, and the association between risk factors and aorta histopathology. Male Wister rats (n=30) were fed an AIN-93G diet containing 20% fat in the form of fish oil, shortening, or soybean oil for 4 weeks. Total cholesterol (TC), triacylglyceride (TG), and C-reactive protein levels were significantly (P<0.001) lower in the fish oil than in soybean oil and shortening groups. HDL-cholesterol concentrations were significantly different (P<0.001) between groups. In addition, LDL-cholesterol levels were significantly (P<0.001) lower in the fish oil and shortening groups than in the soybean oil group. Insulin and glucose concentrations did not differ among groups. Effect of dietary fat on tissue fatty acid composition significantly differed in abdominal fat and brain compared with RBC, heart, kidney and liver. The aortic wall was significantly (P=0.02) thinner in the fish oil group than in the soybean oil and shortening groups. The aortic wall thickness was positively correlated with TG and TC, but negatively with EPA + DHA levels of all tissues. These results suggested that fish oil had protective effects on aorta histopathology by hypolipidemic action in this rat model.

Obesity can be defined as a metabolic disease due to a increased state of fat tissue caused by an imbalance of calorie intake and use. To define genes that affected by different nutrient, we study gene expression from mice which were fed different nutrient. Epididymal and retro-peritineal adipose tissue were increase in high fat diet feeding mice compared with control, but liver and spleen were not. In serum, total cholesterol were differently increase in high fat diet feeding mice but total triglyceride and free fatty acid were not. That was maybe result of energy balance regulation in vivo system. aP2, PPART2 and FAS genes that were increased during adipogenesis were inclosed in high fat diet fed mice compared with control. In microarray assay, 1.4% of total genes were affected in epididymal adipose tissue by different nutrient. 1.1% of total genes were decreased down 0.5 fold and 0.3% were increased over 2 fold. These results indicated that many genes are affected in adipose tissue by nutrient.

This study was carried out to set a standard of damage compensation by researching state of damage due to noises in laying and prelaying hens. Recently, there are many damage cases in chicken farms near construction site that were caused by noises of construction. Therefore disputes and complaints about economical loss have increased ceaselessly. But we have few research and report such a thing. The result have shown that the weight loss rate was ranged from 9.48% to 23.2% and mortality of laying period of hens was higher than prelaying period. Pathological findings were fatty liver, congestion and hemorrhage of intestine, erosion of proventriculus and gizzard in order of case frequency. And these signs in hens of laying period was more serious than prelaying period. Half-life rate of antibody titers against Newcastle disease and infectious bronchitis in sound stressed hens was no different compared with non-stressed hens. Egg production rate dropped from 38% to 45% according to strength of noises. Before being stressed, hens produced special, large, middle, small-size eggs in the order. But after being stressed, their egg Production rate of middle, small-size Increased while egg production rate of special, large-size decreased. Production rate of soft and broken shell eggs was 0.015% in the stressed flocks higher than 0.005% in the non-stressed flocks.

Dipeptidyl peptidase (DPP)-4 inhibitors, or gliptins, are a class of oral hypoglycemic drugs that have been widely used as a second-line treatment for type 2 diabetes. Gliptins, which were introduced for clinical use a decade ago, have been shown to be beneficial against nonalcoholic fatty liver disease/nonalcoholic steatohepatitis (NASH) in animals and humans. Cenicriviroc (CVC), a dual antagonist of C-C chemokine receptor type 2 and 5, is currently under investigation against NASH and fibrosis. It was previously discovered that evogliptin (EVO) reduces hepatic steatosis in diet-induced obese animals but the effectiveness of EVO on NASH remains unexplored. Here, we compared the effectiveness of EVO and CVC against NASH and fibrosis in mice fed a high-fat and high-fructose diet (HFHF). Biochemical and histological analyses showed that mice fed a HFHF for 20 weeks developed severe hepatic steatosis and inflammation with mild fibrosis. Administration of EVO (0.2% wt/wt) for the last 8 weeks of HFHF feeding significantly reduced hepatic triglyceride accumulation, inflammation, and fibrosis as well as restored insulin sensitivity, as evidenced by lowered plasma insulin levels and the improvement in insulin tolerance test curves. Treatment of mice with CVC (0.1% wt/wt) inhibited hepatic inflammation and fibrogenesis with similar efficacy to that of EVO, without affecting hepatic steatosis. CVC treatment also reduced plasma insulin concentrations, despite no improvement in insulin tolerance. In conclusion, EVO administration efficiently ameliorated the development of NASH and fibrosis in HFHF-fed mice, corroborating its therapeutic potential.

Benign symmetric lipomatosis was initially described in 1846 by Sir Benjamin Brodie. In 1888, Otto Madelung presented 33 cases of benign symmetric lipomatosis and described the classic“horse collar”cervical distribution of the lipomatous tissue. Launois and Bensaude described benign symmetric lipomatosis as a distint syndrome characterized by a diffuse, symmetric, fatty accumulation in the cervical region. This disease is rare condition affecting mostly middle aged alcoholic men and associated with many systemic diseases such as diabetes mellitus, hyperuricemia, renal tubular acidosis, liver enzyme abnormality etc. The condition does not spontaneously involute and surgical excision is the only proven method of treatment, and recurrence is frequent. We experienced six patients of benign symmetric lipomatosis who underwent surgical excision via collar incision which afford wide exposure of the entire cervical area. We report them with the review of literature.

Vitamin C (ascorbic acid) supplementation has been suggested to negatively correlate with obesity in humans and other animals. Previous studies, including ours, have demonstrated that a high-fat diet (HFD) induces obesity and related diseases such as hyperlipidemia, hyperglycemia, insulin resistance, and nonalcoholic fatty liver disease. Here, we investigated the effects of vitamin C on visceral adipocyte hypertrophy and glucose intolerance in C57BL/6J mice. Mice received a low-fat diet (LFD, 10% kcal fat), HFD (45% kcal fat), or the same HFD supplemented with vitamin C (HFD-VC, 1% w/w) for 15 weeks. Visceral adiposity and glucose intolerance were examined using metabolic measurements, histology, and gene expression analyses. Mice in the HFD-VC supplementation group had reduced body weight, mesenteric fat mass, and mesenteric adipocyte size compared with HFD-fed mice. Vitamin C intake in obese mice also decreased the mRNA levels of lipogenesis-related genes (i.e., stearoyl-CoA desaturase 1 and sterol regulatory element-binding protein 1c) in mesenteric adipose tissues, inhibited hyperglycemia, and improved glucose tolerance. In addition, vitamin C attenuated the HFD-induced increase in the size of pancreatic islets. These results suggest that vitamin C suppresses HFD-induced visceral adipocyte hypertrophy and glucose intolerance in part by decreasing the visceral adipose expression of genes involved in lipogenesis.

비알코올성 지방간염(nonalcoholic steatohepatitis, NASH)은 비알코올성 지방간 질환(nonalcoholic fatty liver disease, NAFLD)의 진행질환으로, 중성지방 침착, 염증 및 간 섬유화가 동반되어 간경변증과 간암의 원인이 되는 질환이나, 아직까지 비알코올성 지방간염을 치료하는 뚜렷한 치료제가 없는 실정이다. Poricoic acid (PoA)는 복령의 약효성분으로 여러 약리작용이 보고되었으나 비알코올성 지방간염의 치료 효능은 보고되지 않았다. 따라서 본 연구에서는 PoA가 비알코올성 지방간염의 병인에 작용하여 비알코올성 지방간염을 억제하는지를 in vivo 및 in vitro 연구를 통해 확인하였다. 비알코올성 지방간염을 유도하는 식이(high fat and methionine-choline deficient diet, HFMCD)로 비알코올성 지방간염을 유발한 쥐에서 PoA는 HFMCD에 의해 증가된 간 무게를 감소시켰으며, 간 독성을 나타내는 alanine aminotransferase, aspartate aminotransferase도 감소시켰다. Oil Red O 염색 및 hematoxylin & eosin 염색의 결과에 의하면, PoA는 HFMCD에 증가하는 간 조직 내 중성지방의 생성을 감소시켰으며, qPCR 결과에 의해서도 PoA는 중성 지방 합성과 관련된 유전자들의 발현도 감소시켰다. 또한 간 조직에서 CD68 면역 염색 결과에 의하면, PoA는 HFMCD에 의해 증가는 CD68 면역 염색을 감소시켰으며, 염증과 관련된 유전자 발현도 감소시켰다. 더욱이 Sirius red 염색과 α-smooth muscle actin (α-SMA) 면역 염색으로 간 섬유화 정도를 측정한 결과, PoA는 HFMCD에 증가되는 sirius red 염색과 α-SMA 면역 염색을 유의적으로 감소시켰으며 섬유화 관련 유전자들의 발현도 감소시켰다. 또한, PoA는 palmitate (Pa)로 처리한 간세포 AML12에서 Pa에 의해 증가하는 중성 지방산 합성, 염증 및 섬유화 관련 유전자들의 발현을 감소시켰다. 이상의 결과를 종합하면 PoA는 비알코올성 지방간염의 중요 병인인 중성지방 생성, 염증 및 섬유화를 억제하여 비알코올성 지방간염을 억제함을 확인하였다.
