E. japonica is a well-known medicinal plant in Japan. The leaves of E. japonica were reported to have a hypoglycemic action. However, seeds of E. japonica are discarded and not used. To elucidate for anti-diabetic effects of E. japonica, Type 2 diabetic mice were allocated to control group, E. japonica leaf, and seed extract group. Animals were fed a 2018S Teklad global 18% protein rodent diet. Animals were received daily oral injections of E. japonica leaf or seed extract at a dose of 200 mg/kg body weight for 6 weeks. Body weight, food intake and water intake, and total adipose tissue weight of animals were significantly reduced by feeding of E. japonica leaf extract. All E. japonica extract groups significantly decreased fasting blood glucose, glycosylated hemoglobin levels, size of adipocytes and serum adiponectins. However, they did not have a beneficial effect on the serum triglyceride and cholesterol in the diabetic animals. These results suggest that E. japonica seed and leaf extracts have a antidiabetic effect by controlling of blood glucose and decrease of size of adipocytes in db/db mice and seed extract is more effective in hypoglycemic action than leaf extract.

This study was performed to investigate the anti-hyperglycemia effects of the Triticum aestivum wheat sprout (TAWS) water extracts in the diabetic mice. Diabetic experimental model was established by intraperitoneal injection of streptozotocin into male Balb/c mice. Mice were divided into five groups: normal (CON), diabetic control (DM), and three experimental groups (DM-100, diabetes with TAWS extracts 100mg/kg; DM-50, diabetes with TAWS extracts 50 mg/kg; DM-25, diabetes with TAWS extracts 25 mg/kg). TAWS extracts were administered orally in diabetic mice. Body weight, food intake, and blood glucose levels were recorded for 12 days and blood insulin levels were measured at the day 12. Oral administration of TAWS extracts reduced slightly food intake and induced a little body weight gain in DM-100 groups. The blood level of glucose was decreased in the dose-dependent manner; 55% in the DM-100 group and 39.7% in the DM-50 group. The blood level of insulin also was improved 10 folds in the DM-100 group and 3.6 folds in the DM-50 group compared to the DM group. The contents of total phenolic compounds and total flavonoids in 1 g dry mass of TAWS extracts were 6.6 mg of tannic acid equivalents and 1.0 mg of 8-hydroquinolline equivalents, respectively. In addition, the antioxidant and DPPH radical scavenging activity of TAWS extracts were 1.2 mM and 1.8 mM ascorbic acid equivalents, respectively. These results suggest that TAWS water extracts could contribute to attenuate clinical symptoms of diabetes mellitus.

BACKGROUND/OBJECTIVES: Lactobacillus brevis G101 suppresses the absorption of monosodium glutamate (MSG) from the intestine into the blood in mice. Therefore, the attenuating effect of orally administered G101 on monosodium glutamate (MSG) symptom complex was investigated in humans MATERIALS/METHODS: Capsules (300 mg) containing Lactobacillus brevis G101 ($1{\times}10^{10}CFU/individual$) or maltodextrin (placebo) was orally administered in 30 respondents with self-recognized monosodium glutamate (MSG) symptom complex for 5 days and the rice with black soybean sauce containing 6 g MSG (RBSM) was ingested 30 min after the final administration. Thereafter, the MSG symptom complex (rated on a 5-point scale: 1, none; 5, strong) was investigated in a double blind placebo controlled study. The intensity of the MSG symptom complex was significantly reduced in respondents of the G101 intake group ($2.87{\pm}0.73$) compared to that in those treated with the placebo ($3.63{\pm}1.03$) (P = 0.0016). Respondents in the placebo group exhibited more of the various major conditions of the MSG symptom complex than in the G101 intake group. Although there was no significant difference in the appearance time of the MSG symptom complex between subjects orally administered G101 and those administered the placebo, its disappearance in < 3 h was observed in 69.9% of subjects in the G101 treatment group and in 38.0% of subjects in the placebo group (P = 0.0841). CONCLUSIONS: Oral administration of Lactobacillus brevis G101 may be able to reduce the intensity of the MSG symptom complex.

In this study, Banhasasim-tang extracts (BSTE) have an inhibitory effects on cisplatin-induced decrease of body weights in two mouse model. Cisplatin is the most widely used anticancer drug for treatment of various cancer. However, cisplatin treatment to cancer patients leads to many side effects such as nausea, vomiting and body weight decrease. BSTE has been used to decrease digestive disorders in South Korea. We hypothesize that BSTE improve the cisplatin-induced side effects in mouse models. We found that pre- and co-administration of BSTE inhibited decreases of body weights and food intake by cisplatin in mouse models. But BSTE had no synergistic effects for tumor shrinkage by cisplatin in xenograft model. Collectively, our data suggest that BSTE have great potential as a agent for having decrease effects on side effects by cisplatin in cancer patients.

Gambejaeseup-tang (GBJST) have recently been used as an anti-obesity herbal medicine but their effect and mechanism of action have not been studied. We modified ingredients of GBJST based on the previous experiments about exploring herbs to suppress triglyceride accumulation in 3T3-L1 adipocytes. We investigated the effects of modified GBJST on energy, glucose and lipid homeostasis using female rats with diet-induced obesity and their action mechanism was also determined. Rats fed a high-fat diet (HFD) were divided into 3 groups: rats in each group received 0.2 or 2 g water extracts of modified GBJST (L-GBJST or H-GBJST) or 2 g cellulose per kg body weight (a negative control) on a daily basis. A further group was fed a low-fat diet (LFD) as a positive control. We found that modified GBJST dose-dependently decreased body weight and mesenteric and retroperitoneal fat more than the control. This decrease was due to the reduction in energy intake and the increase of energy expenditure. HFD increased fat oxidation more than LFD and modified GBJST further increased fat oxidation as a major energy source more than the control in a dose-dependent manner. In addition, H-GBJST improved glucose tolerance without changing serum insulin levels during an oral glucose tolerance test. H-GBJST also suppressed the increase of serum total and LDL cholesterol and triglyceride levels by HFD. In conclusion, modified GBJST have a good anti-obesity effect by decreasing energy intake and increasing energy expenditure mainly as fat in female rats with diet-induced obesity. It also improves glucose tolerance and lipid metabolism.

Nitrite plays a major role in inhibiting the growth of foodborne pathogens, including Clostridium botulinum (C. botulinum) that causes botulism, a life-threatening disease. Nitrite serves as a color-fixing agent in processed meat products. However, N-nitroso compounds can be produced from nitrite, which are considered as carcinogens. Thus, consumers desire processed meat products that contain lower concentrations (below conventional concentrations of products) of nitrite or no nitrite at all, although the portion of nitrite intake by processed meat consumption in total nitrite intake is very low. However, lower nitrite levels might expose consumers to risk of botulism poisoning due to C. botulinum or illness caused by other foodborne pathogens. Hence, lower nitrite concentrations in combination with other factors such as low pH, high sodium chloride level, and others have been recommended to decrease the risk of food poisoning. In addition, natural compounds that can inhibit bacterial growth and function as color-fixing agents have been developed to replace nitrite in processed meat products. However, their antibotulinal effects have not been fully clarified. Therefore, to have processed meat products with lower nitrite concentrations, low pH, high sodium chloride concentration, and others should also be applied together. Before using natural compounds as replacement of nitrite, their antibotulinal activities should be examined.

Opuntia humifusa contains high levels of antioxidants including vitamin C, flavonoids and polyphenols, which may provide beneficial effects such as hypolipidemic activity and the reduction of atherosclerosis in postmenopausal women. This study was conducted to determine if the intake of O. humifusa seeds powder (OHS) regulates lipid concentrations, glutamate-oxaloacetate transaminase (GOT), and glutamate-pyruvate transaminase (GPT) in the serum of ovariectomized rats. Sprague-Dawley female rats were randomly assigned to either a sham-operated group (Sham) or one of the following four ovariectomy (OVX) subgroups: OVX with vehicle (OVX), OVX with 100, 200, and 500 mg/kg/day OHS (OHS100, OHS200, OHS500). Daily oral administration of OHS was initiated one week after ovariectomy and continued for seven weeks. Upon completion of treatments, organs were weighed and GOT, GPT, total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C) levels were determined enzymatically. No significant differences in feed intake and organ index were observed among the groups. Significant decreases in GPT, TC and LDL-C (p<0.05) were observed in all of the OHS groups (OHS100, 200 and 500), while no significant changes in HDL-C were observed. In addition, the OHS200 and OHS500 treatment groups exhibited a lower level of serum GOT compared to the OVX group. These results indicate that supplementation with O. humifusa seeds could induce favorable changes in serum lipoprotein and lipid profiles, which frequently worsen with inadequate estrogen availability.

The purpose of this study was to determine the effects of taurine supplementation and taurine depletion on blood glucose and blood lipid concentrations in insulin-treated diabetic rats. Four groups of Sprague-Dawley male rats were fed the purified diet for 3 weeks ; nontaurine-supplemented diabetic rats(E0), nontaurine-supplemented diabetic rats with insulin treatment(E0＋I), 1% taurine-supplemented diabetic rats with insulin treatment(E1＋I) and taurine-depleted diabetic rats with insulin treatment(EA＋I). Diabetes was induced by streptozotocin injection(50mg/kg B.W.). Isophane insulin was given subcutaneously into the abdominal wall of the diabetic rats(4 unit/rat/day). E1＋I were supplemented with 1% taurine in drinking water. To induce taurine depletion, EA＋I were treated with 5% $\beta$-alanine in drinking water. E1＋I had significantly higher body weight compared to that of E0. The food intakes of E1＋I and E0＋I were significantly decreased compared to that of E0. There was no sigfniciant difference in food intake between E1＋I and E0＋I. The water intake of rats was significantly different among the groups ; E0>E0＋I>E1＋I>EA＋I. The urine volume of E0 was significantly increased compared to those of insulin-treated goups. The blood glucose concentration of E0 was significantly increased compared to those of insulin-treated groups. In the oral glucose tolerance test(OGTT), E0＋I and E1＋I had significantly lower blood blucose concentrations compared to E0 after 30 min. Also EA＋I had significantly lower bloodglucose concentrtion compared to E0 and E0＋I. The plasma total cholesterol and LDL-cholesterol concentratons of EA＋I were significantly incrased compared to those of other groups. Therefore, it may be suggested that tuarine supplementation is useful for insulin-dependent diabetes in order to prevent diabetic complications suchas cardiac vascular diseases.

The Efficacy of SHI-1909 was investigated in comparision with predinisolone in acetic acid and Picrylsulfonic acid solution (TNBS)-induced rat inflammatory bowel disease (IBD) for 5 days. 7% Acetic acid and 5% TNBS solution were administered with polyethylene (P.E) tube inserted to rats intracolon, which causing colitis to the rats. The acetic acid and TNBS control group (the saline treated colitic rat) exhibited ulceration and inflammation of the distal colon with formation of granuloma and pathologic connections. We checked the inflammatory parameters like rat's weight, food intake quantity change during administration. After 5 days, we sacrificed the rats and checked the colon's length, ulcer and pathologic condition. Oral treatment with SHI-1909 resulted in significant recovery of macroscopic parameters like weight and diet intake change. Especially, SHI-1909 had a more potent effect than prednisolone on macroscopic colonic damage score. We can suggest that SHI-1909 could be a promising drug in the treatment of IBD.
