Chronic acquired hepatocerebral degeneration(CAHD) is a heterogenous that can occur with a primary neurologic, hepatic, or combined presentation. Symptoms and signs of that included progressive dementia, dysarthria, involuntary movements(including tremor, asterixis, and choreoathetosis), ataxia of limb and gait, typically in a patient with chronic liver cirrhosis. Characteristic radiologic findings is high signal on globus pallidus on T1W1 MRI. Recently, we experienced a patients, a 73-year-old female with CAHD presenting mental change, cognitive deficits, and various involuntary movement. In our patient, T1 weighted MRI of the brain showed symmetric high signal intensity in both basal ganglia. Increased ammonia $level(226{\mu}g/dl)$ in whole blood and a multiple anomalous vessels with spleno-renal shunt on abdominal CT were found. But, liver cirrhosis is absent. In admission care, these mental change and involuntary movements had a good response to herbal medication. We report on patient with CAHD which had a spontaneous spleno-renal shunt without liver disease.

Objectives : We investigated the effects of Sopungsungj-won(Shufengshunqjvuan) (SSEx1, SSEx2) on the metabolic syndrome in high-fat diet induced obese mice. Methods: 8 weeks old, high fat diet induced obese male mice were divided into 4 groups: C57BL/6 lean control, obese vehicle control, SSEx1, SSEx2. After mice were treated with SSExl, SSEx2 for 12 weeks, we measured body weight gain, food intake, feeding efficiency ratio, fat weight, plasma leptin, insulin, glucose and lipid levels. We also observe the morphology and count for the numbers of Adipocyte and evaluate the weight of organs and it's function. Results: 1. Compared to Obese Control Group, SSEx1 gained significantly lower body weight and showed lower Feeding Efficiency Ratio. 2. Compared to Obese Control Group, SSEx1 showed lower weights of epididymal adipose tissue, troperitoneal adipose tissue, inguinal adipose tissue, brown adipose tissue. SSEx2 showed higher weights of epididymal adipose tissue, troperitoneal adipose tissue, inguinal adipose tissue, brown adipose tissue. 3. Compared to Obese Control Group, the size of adipocytes was significantly decreased by SSEx1, whereas the number of adipocites per unit was significantly increased. Hepatic lipid accumulation was decreased significantly by SSEx1. 4. Concerning the weights of Liver, Heart, Spleen, Kidney and Pancreas, SSEx1, SSEx2 showed little differences with those of Lean Control, Obese Control. 5. Compared to Obese Control Group, SSEX1, SSEx2 showed lower level of plasma triglyceride, but SSEx1 had significance only. SSEx1, SSEx2 showed little lower level of plasma HDL-cholesterol. LDL-cholesterol, total cholesterol, but had no significances. 6. Concerning the levels of plasma glucose, insulin and leptin, SSEx1 and SSEx2 showed littele changes with those of Lean Control, Obese Control. 7. The leves of Plasma AST, AST, ALT, free fatty acid, BUN, creatinine were in the physiological range at 4 groups all: Lean Control, Obese Control, SSEx1, SSEx2. Conclusions : These results showed SSEx1 can be used as therapeutic agent for Obesity and metabolic syndrome caused by long-period high fat diet.

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.

Bisphenol A, an everywhere chemical, is applied as a plasticizer in polycarbonate plastics, which often used in our everyday products and in epoxy resins as protective coatings and linings for food and beverage cans for decades. Human exposure to BPA may lead to adverse effects by interfering with oestrogen receptors. Our present study was conducted to investigate the protective effects of selenium (Se) and vitamin E (Vit E) on BPA-induced damage in the liver of male rats. Animals were randomly divided into four groups: the first group received olive oil and served as control. The second group received both (Se + Vit E) (0.5 mg/kg diet; 100 mg/kg of diet). The third one treated orally by (10 mg/kg b.w.) of BPA. The last group received (Se + Vit E) (0.5 mg/kg diet; 100 mg/kg of diet) concomitantly with (10 mg/kg b.w.) BPA. Exposure to BPA for three weeks engendered a hepatic disorder. An increased AST and ALT enzymatic activity was noticed in BPA-treated group as compared to other groups. Furthermore, a change in glucose, cholesterol, LDL-C, HDL-C, albumin, and bilirubin level was remarkable. Moreover, exposure to BPA increased malondialdehyde levels while reduced gluthatione content was decreased in the liver homogenate. A decrease in glutathione peroxidase, glutathione s-transferase and catalase activities was observed in the same group. Administration of selenium and vitamin E through the diet in BPA treated rats ameliorated the biochemical parameters cited above. In addition, an improvement in activities of liver enzymes was recorded. The histological findings confirmed the biochemical results. The model of this study that we employed characterized the relationships between BPA-induced hepatotoxicity and its alleviation by natural antioxidants like selenium and vitamin E.

Tenofovir nanoparticles are novel therapeutic intervention in human immunodeficiency virus (HIV) infection reaching the virus in their sanctuary sites. However, there has been no systemic toxicity testing of this formulation despite global concerns on the safety of nano drugs. Therefore, this study was designed to investigate the toxicity of Tenofovir nanoparticle (NTDF) on the liver and kidney using an animal model. Fifteen adult male Sprague-Dawley (SD) rats maintained at the animal house of the biomedical resources unit of the University of KwaZulu-Natal were weighed and divided into three groups. Control animals (A) were administered with normal saline (NS). The therapeutic doses of Tenofovir (TDF) and nanoparticles of Tenofovir (NTDF) were administered to group B and C and observed for signs of stress for four weeks after which animals were weighed and sacrificed. Liver and kidney were removed and fixed in formal saline, processed and stained using H/E, PAS and MT stains for light microscopy. Serum was obtained for renal function test (RFT) and liver function test (LFT). Cellular measurements and capturing were done using ImageJ and Leica software 2.0. Data were analysed using graph pad 6, p values < 0.05 were significant. We observed no signs of behavioural toxicity and no mortality during this study, however, in the kidneys, we reported mild morphological perturbations widening of Bowman's space, and vacuolations in glomerulus and tubules of TDF and NTDF animals. Also, there was a significant elevation of glycogen deposition in NTDF and TDF animals when compared with control. In the liver, there were mild histological changes with widening of sinusoidal spaces, vacuolations in hepatocytes and elevation of glycogen deposition in TDF and NTDF administered animals. In addition to this, there were no significant differences in stereological measurements and cell count, LFT, RFT, weight changes and organo-somatic index between treatment groups and control. In conclusion, NTDF and TDF in therapeutic doses can lead to mild hepatic and renal histological damage. Further studies are needed to understand the precise genetic mechanism.

Objectives : It is the objective of this study to compare hepatotoxicity of nickel chloride and cadmium chloride with each other through IPRL(Isolated Perfused Rat Liver) method. Methods : Biochemical indicator of hepatic function such as AST(aspartate aminotransferase), ALT(alanine aminotransferase), LDH(lactate dehydrogenase) and perfusion flow rate were used as the indicator of hepatotoxicity. Oxygen consumption rate were used as vability indicator. $300({\pm}50)g$ - weighted rats were allocated randomly to each group($0{\mu}M,\;50{\mu}M,\;200{\mu}M\;NiCl_2\;and\;CdCl_2$ exposure) by 5, totally 25. After Krebs-Ringer bicarbonate butler solution flowed into the penal vein and passed the liver cell, it flowed out of vena cava. Liver was administered with each $NiCl_2\;and\;CdCl_2$ of each concentration and observed with buffer solution sampling time. Butler which got out of liver was sampled and then biochemical indicator of hepatotoxicity was measured. Results : AST, ALT, and LDH in buffer increased with sampling time much more in $CdCl_2$ exposure group than $NiCl_2$ exposure group in both 50 and $200{\mu}M$ and statistical significance w3s verified with 2-way repeated ANOVA. Viability was decreased more and more in all substances during passed time. Conclusions : It is inferred that $CdCl_2$ has stronger hepatotoxicity than $NiCl_2$. IPRL method would be used widely for acute hepatotoxicity when considerating the benefit of it.

The leaves (KPL) of Kalopanax pictus (KP) are used as a vegetable or a functional food in Korean society. The stem bark (Kalopanacis Cortex, KPS) has been traditionally used to treat neurotic pain, rheumatoid arthritis and diabetic disease. This research was undertaken to demonstrate that the leaf extract of KP (KPL) has also the antinociceptive and antiinflammatory effects like the extract (KPS) of Kalopanacis Cortex and to compare the activity levels of several extracts obtained from KP. Antinociceptive and antiinflammatory effects were measured against the extracts described as followings; KPL-1 (the MeOH extract obtained from the leaf shoot of KP collected on May), KPL-2 (the MeOH extract from KP collected on June), KPL-3 (the MeOH ectract from KP with no thorns), KPS-1 (MeOH extract from KPS of a Korean habitat), KPS-2 (MeOH extract from KPS of a Chinese habitat). The antimociceptive test undertaken by acetic acid-induced writhing, hot plate-, and tail-flick methods using mice. The anti-inflammatory test was also undertaken by measuring the edema in the carrageenan-induced test. The order of activity potency in the antinociceptive and antiinflammatory assays was commonly shown as followings: KPL-3>KPS>1>KPS-2>KPL-1>KPL-2. This order was also observed in acetic acid-induced vascular permeability test. The antiinflammatory activity in carrageenan-induced assay was also observed as the following order: KPL-3>KPS- 1>PS-2>KPL-1>KPL-2. In addition, adjuvant-induced rats were used for a model to assess the oxidative stress. Treatment of the rat with the extracts reduced serum thiobarbituric acid-reactive substances (TBARS), hydroxy radical(OH) and superoxide dismutase(SOD) activity caused by FCA together together with the inhibition of hepatic TBARS level and lipofuscin content. The above finding suggests that the leaf extract has the antinociceptive and antinflammatory activity. It is also suggested that KPL-3 with more potent activity than other tested extracts could be developed for a new available biomaterial.

The objective of this study was to evaluate the effects of glycoprotein isolated from Morus indica L. (MIL) on plasma cholesterol levels and on the activities of hepatic detoxicant enzymes in ICR mice. MIL glycoprotein evidenced good scavenging activities against lipid peroxyl radicals. When the mice were treated with Triton WR-1339, the levels of total cholesterol (TC) and low-density lipoprotein (LDL)-cholesterol in plasma increased significantly by 53.9 and 47.5 mg/dL, respectively, as compared to the controls. However, when pretreated with MIL glycoprotein $(100{\mu}g/mL)$, ICR mice showed marked reductions to 55.4 and 47.0 mg/dL, as compared to Triton WR-1339 treatment alone. Interestingly, high density lipoprotein cholesterol levels were unchanged. These results indicate that the MIL glycoprotein is capable of scavenging lipidperoxyl radicals, lowering plasma lipid levels, and increasing the activities of detoxicant enzymes in the mouse liver.

This study was to investigate the potential effects of fermented Angelica gigas Nakai (FAG) at 5% (w/w) levels in Sprague-Dawley strain rats, which were intoxicated with 1% (w/w) orotic acid (OA) for 10 days. The activities of several hepatic enzymes, including aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), lactate dehydrogenase (LDH), and cholinesterase were increased when OA was treated, but these parameters were significantly decreased by FAG administration. OA treatment induced a significant increase in the thiobarbituric acid reactive substances (TBARS) levels, which was attenuated by FAG administration. Liver nonheme ion was decreased in the OA treatment group and was significantly increased in FAG administration, which suggests that lipid peroxidation contents are inversely correlated with liver nonheme ion content. The glutathione concentration was significantly decreased in the OA treatment group compared with the normal group, but this concentration was significantly increased in the FAG group, and it showed the antioxidant ability of glutathione. Based on these results, fermented Angelica gigas Nakai is a material with significant potential for development into a health food that can improve fatty liver conditions.

Purpose: Glycogen storage disease type III (GSD-III), is a rare autosomal recessive disorder of glycogen metabolism. The affected enzyme is amylo-1,6-glucosidase, 4-alpha-glucanotransferase (AGL, glycogen debranching enzyme), which is responsible for the debranching of the glycogen molecule during catabolism. The disease has been demonstrated to show clinical and biochemical heterogeneity, reflecting the genotype-phenotype heterogeneity among different patients. In this study, we analyzed mutations of the AGL gene in three unrelated Korean GSD-III patients and discussed their clinical and laboratory implications. Methods: We studied three GSD-III patients and the clinical features were characterized. Sequence analysis of 35exons and part exon-intron boundaries of the AGLgene in patients were carried out by direct DNA sequencing method using genomic DNA isolated from patients' peripheral leukocytes. Results: The clinical features included hepatomegaly (in all patients), seizures (in patient 2), growth failure (in patients 1), hyperlipidemia (in patients 1 and 3), raised transaminases and creatinine kinase concentrations (in all patients) and mild EKG abnormalities (in patients 2). Liver transplantation was performed in patient 2due to progressive hepatic fibrosis. Administration of raw-corn-starch could maintain normoglycemia and improve the condition. DNA sequence analysis revealed mutations in 5 out of 6 alleles. Patient 1 was a compound heterozygote of c.1282 G>A (p.R428K) and c.1306delA (p.S603PfsX6), patient 2 with c.1510_1511insT (p.Y504LfsX10), and patient 3 with c.3416 T>C (p.L1139P) and c.l735+1 G>T (Y538_R578delfsX4) mutations. Except R428K mutation, 4 other mutations identified in3 patients were novel. Conclusion: GSD-III patients have variable phenotypic characteristics resembling GSD-Ia. The molecular defects in the AGL gene of Korean GSD-III patients were genetically heterogeneous.
