Glycogen storage disease (GSD) and mucopolysaccharidosis (MPS) are both independently inherited disorders. GSD is a member of a group of genetic disorders involving enzymes responsible for the synthesis and degradation of glycogen. GSD leads to abnormal tissue concentrations of glycogen, primarily in the liver, muscle, or both. MPS is a member of a group of inherited lysosomal storage diseases, which result from a deficiency in specific enzymatic activities and the accumulation of partially degraded acid mucopolysaccharides. A case of a 16-month-old boy who presented with hepatomegaly is reported. The liver was four finger-breadth-palpable. A laboratory study showed slightly increased serum AST and ALT levels. The liver biopsy showed microscopic features compatible with GSD. The liver glycogen content was 9.3% which was increased in comparison with the reference limit, but the glucose-6-phosphatase activity was within the normal limit. These findings suggested GSD other than type I. Bony abnormalities on skeletal radiographs, including an anterior beak and hook-shaped vertebrae, were seen. The mucopolysaccharide concentration in the urine was increased and the plasma iduronate sulfatase activity was low, which fulfilled the diagnosis criteria for Hunter syndrome (MPS type II). To the best of the authors' knowledge, this is the first case of GSD and Hunter syndrome being identified at the same time.

This study investigated black garlic and mugwort extracts have anti-stress activity. The antioxidant activities of extracts from black garlic (BEP), mugwort (MEP), and three mixtures (MPA, 95:5; MPB, 90:10; MPC, 85:15, w/w% for BEP and MEP, respectively) were tested in vitro. DPPH and ABTS radical scavenging activities for the mixtures (MPA, MPB and MPC) were significantly elevated in a dose-dependent manner by the amount of mugwort extract. A restraint stress was imposed on six groups of Sprague-Dawley rats supplemented with an AIN-93 diet (RSC) or one of five kinds of hot water extract drinks containing (black garlic, RS1; mugwort, RS2; and mixtures of black garlic : mugwort at 95:5, RS3; 90:10, RS4, and a mixture of black garlic : mugwort : apple extract : xylitol=90.25:4.75:2:3, RS5; v/v%) for 4 weeks. The normal group was fed with the AIN-93 diet and not exposed to restraint stress. Food intake was higher in the group fed with garlic extract (RS1), while the body weight gain and food efficiency ratio did not significantly change. The total serum cholesterol content in the RS1 and RS2 groups was significantly lower than the RSC group (control), and the RS5 group was not significantly different compared to the RS3 group. The serum triglyceride content was significantly higher RS3~RS5 groups than RS1 and RS2 groups. In terms of HDL-C and LDL-C contents, AI and CRF in the serum were not significantly different between RS3 and RS5 groups. AST and ALP activities of RS1~RS5 groups were significantly lower than the RSC group. The liver total lipid and cholesterol contents of RS1~RS5 groups were significantly lower than RSC group, and triglyceride content was significantly lower in the RS1 group. Glycogen in the liver tissue was significantly higher in the RS2 and RS3 group compared to the RSC group. These results show that the intake of a mixture of black garlic and mugwort extracts may be effective in the alleviation of hyperlipidemia caused by restraint stress.

This study was conducted to investigate the cholesterol lowering effect and weight reduction of autoclaved soy flour, cheonggulgang and doenjang, which are fermented using Bacillus subtilis DJI, in rats fed a high-fat/high-cholesterol diet. Male Sprague-Dawley rats weighing 250 g, were divided into five groups; a normal diet group (N), a high-fat/high-cholesterol diet group (HFC), a high-fat/high-cholesterol diet with 5% autoclaved soy flour group (HFC-S), a high-fat/high-cholesterol diet with 5% cheonggulgang group (HFC-CJ), and a high-fat/high-cholesterol diet with 5% deonjang group (HFC-DJ). The body weight gain and adipose tissues weights increased in rats fed a high-fat/high-cholesterol diet, but decreased significantly in rats fed autoclaved soy flour, cheonggulgang and doenjang, compared with the HFC group. Food intake was lower in the all HFC groups (HFC, HFC-S.HFC-CJ and HFC-DJ) than that of the N group, However, there was no differences in the food intake between HFC diet groups. Serum triglyceride level increased with a high-fat/high-cholesterol dietgroup whereas HFC-CJ and HFC-DJ groups were markedly decreased serum triglyceride levels compared with N group. Levels of serum total cholesterol and LDL-cholesterol, and level of total cholesterol in the liver were significantly lower in the HFC-S group, the HFC-CJ group and the HFC-DJ group than that of the HFC group, but exerted no significant change between the HFC groups on levels of total lipid and triglyceride in the liver. Fecal total lipid content increased in the HFC-CJ group and the HFC-DJ group than those of the HFC group and HFC-S group. The activities of heparin-releasable lipoprotein lipase (HR-LPL) and total-extractable LPL in adipose tissues decreased in the HFC-S group, the HFC-CJ group and the HFC-DJ group compared with the HFC group. These results suggest that dietary cheonggulgang and doenjang may exert cholesterol-lowering effect and prevent obesity.

To investigate the hepatic oxygen free radical metabolizing system and changes of serum cholesterol levels in rats fed a diet supplemented with Monascus pigment (MP), Sprague-Dawley rats weighing about 300 g have been fed a diet supplemented with 2% or 4% MP for a month. The rats fed 2% MP supplemented diet gained less body weight than the control rats and those fed 4% W supplemented diet. Those fed 2% or 4% MP supplemented diet had no remarkable changes in liver function on basis of liver weight/body weight, serum levels of xanthine oxidase, alanine amino transferase activity In rats fed 2% and 4% MP supplemented diet, hepatic cytochrome P45O dependent aniline hydroxylase activity significantly (p<0.05) declined about 32%, 37% respectively and showed no significant differences between rats fed 2% and 4% MP supplemented diet whereas those fed 2% MP supplemented diet showed about 29% increased hepatic xanthine oxidase activity. And hepatic glutathione S-transferase and glutathione peroxidase activites in rats fed 2% MP supplemented were more increased by about 17%, 28% respectively than the control rats. There were no significant differences both in between those fed 2% and 4% MP supplemented diet. Especially rats fed 2% or 4% MP supplemented diet showed a significant (p<0.05) increase in hepatic catalase activity by 41%, 25% compared with control rats and those fed 4% MP supplemented diet showed more decrease in tendency of catalase activity than those 2% MP supplemented diet. But hepatic superoxide dismutase activity and glutathione content were appeared to be similar value among three groups. On the other hand, rats fed 2% MP supplement diet showed 17% increased levels of serum HDL-choresterol and 26% decreased value of LDL-cholesterol and serum level of triglyceride. But no different value were appeared between those fed 2% and 4% MP supplemented diet. Especially in those fed 2% and 4% MP supplemented diet, artherogenic index were significantly (p<0.05) declined by 37%, 29% respectively compared with control. In conclusion, it is likely that rats fed a diet supplemented with a proper quantity of MP may have the potential of oxygen free radical detoxication and lowering of artherogenic index.

We investigated the cholesterol-lowering and body-weight loss effects of Cheonggukjang fermented using Bacillus subtilis DJI in rats fed a high-fat/high-cholesterol diet for 4 weeks. Weight-matched male Sprague-Dawley rats were assigned to one of four groups: a normal diet group (N), a high-fat/high-cholesterol diet group (HFC), a high-fat/high-cholesterol diet with DJI Cheonggukjang group (HFC-SCK), and a high-fat/high-cholesterol with commercial Cheonggukjang group (HFC-CCK). All of body weight and liver and adipose tissue weights increased in animals fed a high-fat/high-cholesterol diet, but decreased significantly in rats fed Cheonggukjang powder, compared with the HFC group. Food intake was lower in the HFC group than in the N group, and that of the HFC-CCK group was the lowest among the four groups. Serum total cholesterol levels were significantly lower in the Cheonggukjang-powder fed groups than the other groups. Serum phospholipid and HDL-cholesterol concentrations were significantly decreased in HFC animals and were markedly increased upon feeding of a Cheonggukjang-containing-diet. Levels of serum LDL-cholesterol, the atherogenic index, and cardiac risk factor assessment indications tended to be decreased in Cheonggukjang powder-fed groups, compared with the HFC group. The total cholesterol level in liver tissue was increased by feeding of a high-fat/high-cholesterol diet, and was significantly reduced when Cheonggukjang powder was present in the diet. The levels of total lipids and triglycerides in adipose tissues were lower in the HFC-SCK group than in the HFC group, whereas no significant differences were evidence when the HFC and the HFC-CCK groups were compared. Fecal weight, moisture level, and total lipid content increased in animals fed Cheonggukjang powder. The activities of HR-LPL and TE-LPL in adipose tissues were increased in the HFC group compared with the Cheonggukjang powder-fed groups. These results indicate that dietary Cheonggukjang may improve lipid metabolism and prevent obesity and hyperlipidemia.

The red pepper (Capsicum annuum L.) is one of the most important vegetables in traditional Korean food, containing vitamins A, C, and E, polyphenol, and flavonoids. In addition, red peppers have high anti-oxidant ability and are known to be effective in preventing obesity, diabetes, hypertension, digestive disorders, stress, and aging. In this study, we investigated the effects against obesity and diabetes of both fermented and non-fermented red pepper. C57BL/6N mice with induced obesity from an eight-week 45% high fat diet (HFD) were then fed either an HFD or diets containing 2.5% non-fermented red pepper marc (NRM), 1.25% fermented red pepper marc (FRM), or 2.5% FRM for a further eight weeks. An oral glucose tolerance test was performed seven weeks after dietary intake, and body weight, liver, epididymal fat weight, serum insulin level, and HOMA-IR were measured and a lipid content test performed at eight weeks. The results show that the 2.5% FRM diet reduced body and tissue weight, lipid content, serum insulin levels, and HOMA-IR compared to the 2.5% NRM and HFD diets. These results suggest that fermented red pepper is effective against obesity and diabetes. We will use this information as the basic data for the development of health food materials using red pepper.

A Feeding trial was conducted to study the effects of three different sources and two levels of dietary gelatinized carbohydrate (GC) on nutrient utilization, growth, tissue composition and tissue enzyme activities of fingerlings of Catla catla (15.1-15.3 g). Six isocaloric (17.1-17.5 kJ/g) semi-purified diets were prepared either with rice, corn or tapioca at 40 or 50% GC each. The crude protein (CP) level used in the diet was 35% and 25% for 40% and 50% GC level, respectively to study the protein sparing effect of GC. The degree of gelatinization was higher for corn and tapioca than rice under similar cooking conditions. After a 60-d feeding trial, dry matter, carbohydrate, protein and lipid digestibility were higher in tapioca fed groups at both the levels of GC. However, the highest specific growth rate (SGR) and protein efficiency ratio (PER) were observed in the corn fed groups at 50% GC level indicating better utilization of nutrients from gelatinized corn. Feed conversion ratio (FCR) was almost similar in corn and tapioca fed groups between two levels of GC but in rice fed groups, FCR was lower in 40% GC than 50% GC level. The results indicated higher protein-sparing effect in corn and tapioca fed groups than rice fed groups. The order of gelatinized carbohydrate utilization in Catla catla fingerlings at 50% GC level was corn>tapioca>rice. At 40% GC level, corn and tapioca were comparable and more efficiently utilized than rice. In the corn fed groups, 50% GC was comparable with 40% GC level, whereas in rice and tapioca fed groups the 40% GC was better in terms of nutrient utilization. Liver glycogen content and hepatosomatic index were significantly (p<0.05) higher in those groups fed high GC (50%) irrespective of carbohydrate sources. Higher intestinal amylase and glucose-6-phosphate dehydrogenase activities were observed in higher GC fed groups than the lower GC groups. No mortality was found in any groups at any levels of GC.

To evaluate the antioxidative and antiaging effects of buchu in vivo system, 2% or 5% buchu diets were fed to ICR mice for 13 months and lipid peroxidation, protein oxidation, activities of antioxidative enzymes and total glutathione content on liver were measured. Hepatic TBARS contents did not show differences among diet groups, while buchu diet suppressed the protein oxidation significantly. SOD activities of control diet group decreased slowly after 7 month but buchu diet increased its activities steeply for first 3 month and continued to increase twice or three times higher than control diet during 13 month. While GSH-Px activities of control diet group were increased slightly with age, buchu diet increased its activities twice or three times higher than control. While catalase activities of control diet group were almost not changed with age, buchu diet increased its activities in both 2% and 5% diet groups. Total hepatic glutathione contents were gradually increased with age, while buchu diets In-creased its contents remarkably. According to this study, many antioxidative materials and sulfides compounds containing buchu seems to protect antioxidative systems on ICR mice.

Oxidative stress can play a key role in cadmium (Cd)-induced dysfunction. The present study examined the effect of pine needle water extract (PN) on Cd-induced oxidative stress in rats. Sprague-Dawley male rats were divided into three groups: normal group, Cd control group (Cd) and PN-administered Cd group (Cd-PN). $CdCl_2$ in 0.9% NaCl was administered orally with a dose of 5mg/kg of body weight/week, while the PN was administered orally with a dose of 1.26g/kg of body weight/day. Body weight gain was not different between groups, whereas food intakes were significantly lower in the Cd-PN group than in normal or Cd group. Relative liver weight was significantly increased by cadmium administration compared to the normal group. Hepatic cytochrome P450 was significantly lower in Cd and Cd-PN groups than in normal group, while xanthine oxidase and alcohol dehydrogenase activities were significantly higher in the Cd-PN group than in normal or Cd group. Increased hepatic superoxide dismutase, monoamine oxidase, catalase, and glutathione peroxidase activities by cadmium administration were significantly decreased by PN supplement. PN did not affect the hepatic glutathione content in cadmium-administered rats; however, PN significantly lowered the hepatic lipid peroxide level and plasma alanine transferase activity compared to the Cd control group. These results suggest that the PN may alleviate Cd-induced oxidative stress without hepatotoxicity.
