A one year old spayed female Bichon Frise dog presented with gait abnormalities and seizure. Serum biochemical results showed elevated levels of alkaline phosphatase, alanine aminotransferase, and ammonia. Serum bile acid level was also increased to be over 30 μmol/L on preprandial. Urinalysis identified the presence of ammonium urate crystal. Abdominal ultrasonography and CT revealed aberrant, tortuous, and multiple small vessels connected to the caudal vena cava between left kidney and caudal vena cava. Macroscopic specific findings associated with extrahepatic congenital portosystemic shunts (PSS) or other liver diseases were not identified. Liver biopsy was performed. Histopathologic evaluation revealed hepatic lobular hypoplasia with portal arterial duplication and vascular shunts. Based on these finding, this case was diagnosed as multiple acquired PSS secondary to hepatic microvascular dysplasia (HMD) and hepatic encephalopathy. A liver biopsy is recommended to differentiate HMD from other liver diseases and to confirm HMD when a young dog has multiple acquired PSS.

A 2-year-old female Pekingese dog was presented with primary complaints including exercise intolerance and neurological sign associated with hepatic encephalopathy. The major findings in clinical examination included an intermittent seizure, a slow heart rate with pulse deficit, leukocytosis and anemia in hemogram, elevated pre- and post-prandial serum bile acid and hepatic enzymes, hypoproteinemia, coagulopathy, ammonium urate crystaluria and bilirubinuria. Diagnostic tests revealed an intrahepatic portosystemic shunt complicated with a second degree atrioventricular block and QT prolongation. The case was successfully treated with a transvenous coil embolization. Clinical signs were gradually improved and cardiac bradyarrhythmia disappeared. This case is a rare case of intrahepatic portosystemic shunts complicated with a cardiac bradyarrhythmia in a small breed dog fixed by a transvenous coil embolization.

Bacillus subtilis and Enterococcus faecium are commonly used probiotics. This study aimed to identify the effect of live combined Bacillus subtilis R0179 and Enterococcus faecium R0026 (LCBE) on obesity-associated hyperlipidemia and gut microbiota in C57BL/6 mice. Forty male C57BL/6 mice were divided into four groups: normal group (N group), model group (M group), low-dose group (L group), and high-dose group (H group). Mice were gavaged with LCBE at 0.023 g/mice/day (L group) or 0.23 g/mice/day (H group) and fed with a high-fat diet for 8 weeks. In vitro E. faecium R0026 showed an ability to lower the low-concentration of cholesterol by 46%, and the ability to lower the high-concentration of cholesterol by 58%. LCBE significantly reduced the body weight gain, Lee index, brown fat index and body mass index of mice on a high-fat diet. Moreover, LCBE markedly improved serum lipids (including serum triglyceride, total cholesterol, low-density lipoprotein and high-density lipoprotein) while also significantly reducing liver total cholesterol. Serum lipopolysaccharide and total bile acid in L and H groups decreased significantly compared with M group. PCR-DGGE analysis showed that the composition of gut microbiota in the treatment groups was improved. Akkermansia muciniphila was found in H group. The PCA result indicated a similar gut microbiota structure between LCBE treatment groups and normal group while the number of bands and Shannon diversity index increased significantly in the LCBE treatment groups. Finally, qPCR showed Bifidobacterium spp. increased significantly in H group compared with M group, LCBE alleviated liver steatosis and improved brown adipose tissue index.

The youngkaechulgamtang (Y) composed of four herb drugs, including Hoelen (H). Cinnamomi Ramulus (C). Atractylodis Rhizoma Alba (A) and Glycyrrhizae Radix (G). In oriental medicine literatures, Youngkaechulgamtang is described to be effective in headache, inflammation, uremia, gastritis, diarrhea and hypertension. To estimate the clinical effectiveness of Youngkaechulgamtang, several pharmacological experiments were carried out. The results are summerized as follows; On acetaminophen-induced hepatotoxicity, C+A, Y-G, Y-H, MIX and Y showed the significant elevation of glutathione-S-transferase. But, C+A, Y-G, Y-H, MIX and Y showed the significant suppression of serum aminotransferases. On ANIT-induced cholestasis, U (Ursodesoxycholic acid 50 mg/kg)+$Y_l$ (760 mg/kg) showed the significant increase of bile juice volume. $Y_l,\;Y_2$ (1520 mg/kg), U, $U+Y_l$ showed the remarkable increase of cholic acid. U and $U+Y_l$ showed the significant decrease of total bilirubin. From these results, it is suggest that Y shows liver protective effect against various hepatic injury. Especially, Youngkaechulgamtang was more effective than mixture of 4 ingredients in the elevation of glutathione-S-transferase in acetaminophen-induced hepatotoxicity.

This study was conducted to investigate the effect of water-soluble extract from roasted chicory on the lipid metabolism and oxidative stress in male Sprague-Dawley rats. The experimental groups were divided into three groups ; the normal group, the cholesterol group and the chicory group. Roasted chicory extract was supplemented at 5.0% (w/w) level in the cholesterol diet. Concentration of total cholesterol in serum was significantly higher in the cholesterol group than in the normal group, but this increase in the cholesterol group was significantly decreased by the cholesterol diet supplemented with chicory extract. Concentration of HDL-cholesterol in serum was significantly lower in the cholesterol group than in the normal group, but this decrease in the cholesterol group tended to increase in the chicory group. However, concentrations of triglyceride, phospholipid and nonesterified fatty acid in serum were not significantly different among the groups. Concentrations of triglyceride and cholesterol in liver were significantly higher in the cholesterol and chicory groups than in the normal group. Feces weight and the excretion of cholesterol and bile acid into feces were significantly higher in the chicory group than in other groups. Concentrations of thiobarbituric acid reactive substances (TBARS) in homogenates and microsomal fractions of liver were not significantly different among the groups. On the other hand, concentration of 8-hydroxydeoxyguanosine (8-OHdG) as an useful marker of oxidative stress in urine was lower in the chicory group than in other groups. Concentration of serum glucose was signnificantly lower in the cholesterol group than in the normal group, but that of the chicory group was significantly higher than in the normal group. These results demonstrated that dietary chicory extract exerted the decreasing effect of cholesterol level and oxidative stress in cholesteral-fed rats.

Lactobacillus (LAB) have been reported to exert both harmful and beneficial effects on human and animal health. Recently, it has been reported that dysbiosis and bacterial translocation contribute to liver fibrosis. However, the role of Gram-positive LAB in the situation of chronic liver diseases has not been yet elucidated. Liver injury was induced by bile duct ligation (BDL) in LAB or control-administered mice. Liver fibrosis was enhanced in LAB-administered mice compared with control-treated mice as demonstrated by quantification of Sirius-red positive area, hydroxyproline contents and fibrosis-related genes ($Col1{\alpha}1$, Acta2, Timp1, Tgfb1). Moreover, LAB-administered mice were more susceptible to BDL-induced liver injury as shown by increased ALT and AST level of LAB group compared with control group at 5 days post BDL. Consistent with serum level, inflammatory cytokines ($TNF-{\alpha}$, IL-6 and $IL-1{\beta}$) were also significantly increased in LAB-treated mice. Of note, LAB-treated liver showed increased lipoteichoic acid (LTA) expression compared with control-treated liver, indicating that LAB-derived LTA may translocate from intestine to liver via portal vein. Indeed, responsible receptor or inflammatory factor (PAFR and iNOS) for LTA were upregulated in LAB-administered group. The present findings demonstrate that administration of LAB increases LTA translocation to liver and induces profibrogenic inflammatory milieu, leading to aggravation of liver fibrosis. The current study provides new cautious information of LAB for liver fibrosis patients to prevent the detrimental effect of LAB supplements.

A 1-year-old, female English cocker spaniel (ECS) dog was presented with 3-month history of vomiting and retaking of the vomitus, and chronic weight loss. The client had noticed mild abdominal distension 10 days before. The dog was diagnosed as chronic hepatitis with hepatic cirrhosis based on complete blood count (CBC), serum chemistry profiles, radiography, ascites assessment, bile acid evaluation, and liver biopsy through exploratory laparotomy and necropsy. CBC and serum chemistry profiles revealed mild anemia, slightly elevated hepatic enzymes (ALT and AST), increased creatinine kinase (CK), hyperammonemia, and hypoproteinemia with hypoalbuminemia. Ascites was transudate according to analysis of components. Bile acid assessment (fasting; $174.4{\mu}mol/L$ and postprandial; $198.4{\mu}mol/L$) showed strongly suspected hepatic insufficiency. On radiological findings, ascites was evident. Atrophied liver (especially left side lobes) and distended mesenteric vasculatures were observed by exploratory laparotomy. Histopathological examination of marginal lesion of left lateral lobe of liver by biopsy revealed the necrosis of hepatic cells, dilation of sinusoids, infiltration of neutrophils in sinusoids, and vacuolation of hepatic cytoplasm. The patient had been managed with careful low protein diet and specific supportive therapy (ursodeoxycholic acid, prednisolone, vitamine E, and interferon). Vomiting and ascites disappeared with medical management. The dog was monitored periodically by CBC, serum chemistry and radiographic examination. The dog survived more 18 months with medical therapy. After spontaneous death, necropsy and histopathologic examination were performed.

There is an increasing interest in curcumin (Curcuma longa L.) as a cardiovascular disease (CVD) protective agent via decreased blood total cholesterol and low-density lipoprotein-cholesterol (LDL-cholesterol) level. The aim of this study was to investigate further the potential mechanism in the hypocholesterolemic effect of curcumin by measuring cholesterol 7a-hydroxylase (CYP7A1), a rate limiting enzyme in the biosynthesis of bile acid from cholesterol, at the mRNA level. Male Sprague-Dawley rats were fed a 45% high fat diet or same diet supplemented with curcumin (0.1% wt/wt) for 8 weeks. The curcumin diet significantly decreased serum triglyceride (TG) by 27%, total cholesterol (TC) by 33.8%, and LDL-cholesterol by 56%, respectively as compared to control group. The curcumin-supplemented diet also significantly lowered the atherogenic index (AI) by 48% as compared to control group. Hepatic TG level was significantly reduced by 41% in rats fed with curcumin-supplemented diet in comparison with control group (P < 0.05). Conversely, the curcumin diet significantly increased fecal TG and TC. The curcumin diet up-regulated hepatic CYP7A1 mRNA level by 2.16-fold, compared to control group p (P < 0.05). These findings suggested that the increases in the CYP7A1 gene expression may partially account for the hypocholesterolemic effect of curcumin.

Selecting B. bifidum K-7 out of the bifidobacteria separated from healthy adults in the age of 20s which shows high degree of acid tolerance and bile tolerance, as the main bacterium, this study of find how the bifido-bacteria cause hypocholesterolemic effect in the high fat diet. In order to do this Sparague-Dawley male rats with the initial weight 200 g in average were assigned to four experimental group: 1) high fat diet & milk, 2) high fat diet & the milk added with bifidobacteria, 3) high fat diet & the milk added with microencapsulated bifidobacteria, 4) high fat diet & the fermented milk by bifidobacteria. The numbers of bifidobacteria ingested daily per rat through each type of the above mentioned milk are 10$^{9}$ CFU, 10$^{9}$ CFU respectively. Hypocholesterolemic effect and high level of serum phospholipid were observed in the group fed with fermented milk being compared with the group fed wih no bacterium but not in the groups fed with the milk with bifidobacteria and microencapsulated bifidobacteria. Thus, it was confirmed that the hypocholesterolemic effect is not due to the bifidobacterium itself but to the fermentation on milk.
