The antidiabetic efficacy of Enicostemma littorale Blume (chhota chirayata) aqueous extract was examined in newly diagnosed non-insulin-dependent diabetes mellitus (NIDDM) patients taking only the extract and was administered as two divided doses, half an hour before meal as 5g of aqueous extract per single dose. Out of the 20 patients volunteered, 11 successfully completed the 2 month trial and a significant decrease in fasting & postprandial blood glucose and glycosylated haemoglobin levels were observed along with a significant improvement in the antioxidant parameters of the patients. There was also a significant increase in serum insulin levels in 7 patients after extract treatment as compared to levels before treatment. Serum total cholesterol and serum triglyceride levels were decreased significantly with a significant increase in serum HDLCholesterol levels. Other vital parameters remained stable and no side effects were observed. This is the first report showing the hypoglycemic, antioxidant and hypolipidemic properties of the aqueous extract of E. littorale Blume in non-insulin dependent diabetes mellitus patients.

Objectives: This study investigated the effects of water extract of Aconitum carmichaeli Debx (ACD) on obesity and glucose tolerance in high fat diet induced obese mice. Methods: Five-week-old C5BL/6 mice were fed a high fat diet (HFD) containing or not containing ACD (100 or 300 mg/kg) for 16 weeks. Body weight, food intake, fasting blood glucose, and body temperature were checked every week and then organs, blood serums were collected after 16-week treatment. Furthermore oral glucose tolerance test (OGTT) was carried out after treatment. Results: ACD treated mice showed no significant decreases in body weight and adipose tissue weight as compared with HFD mice. Lipid accumulations in liver and serum lipid levels were not different between ACD treated and HFD mice. However, ACD extract administration significantly and dose-dependently reduced fasted plasma glucose and glucose tolerance as determined by OGTT. Conclusions: The present study demonstrates that ACD might prevent diet-induced glucose tolerance in mouse models of obesity.

In this study, the effects of sitagliptin analogue (SITA) or pioglitazone (PIO) treatment on glucose homeostasis and ${\beta}$-cell dynamics in animal models of type 2 diabetes-Akita and db/db mice were evaluated. After 4-6 weeks of treatment, both SITA and PIO were shown to lower non-fasting glucose levels and reduced glycemic excursion in the intraperitoneal glucose tolerance test. In addition, both drugs preserved normal islet structure and the proportion of ${\beta}$-cells in the islets. Compared to the controls, SITA treatment induced a higher ${\beta}$-cell proliferation rate in Akita mice and a lower rate of apoptosis in db/db mice, whereas PIO treatment induced a lower rate of apoptosis in db/db mice and reduced proliferation rates in Akita mice. In conclusion, both SITA and PIO appear to exert some beneficial effects on the islet structure in addition to glycemic control via different mechanisms that involve ${\beta}$-cell dynamics in Akita and db/db mice.

The study was conducted to investigate the effects of practical variations in feed restriction, pre-slaughter handing and chilling regime on pork quality during ageing. A total of twenty male landraces were allocated into three treatments(i.e., pre-slaughter feeding, stress and chilling regime) in a factorial arrangement. pH, temperature, free calcium ions, WB-shear force, sarcomere length, cooking loss, drip loss and objective color were determined during rigor development and/or 1, 3, 7 d postmortem. Pre-slaughter chasing stress for approximately 15 min had no effects on pH/temperature profile and objective meat quality. There was an interaction(P < 0.05) between the fasting treatment and chi1ling regime for muscle temperature at pH 6.2. Sarcomere length indicated that the current experiment conditions did not induce muscle shortening, with 1.7 to 1.8 ${\mu}m$, in spite of a significant effect of the fasting treatment (P<0.01). Pigs fed until the morning of slaughter showed a low WB-shear force(P < 0.05) until 3 d at I "C. The treatment also resulted in a higher Hunter L* and a*(P < 0.05) at 24 h and 7 d. Fasted pigs showed a significantly(P < 0.05) reduced cooking loss. The current results indicated that feeding upon the morning of slaughter became detrimental on meat color and the negative effect on cooking loss were linearly elevated with increased ageing time. On the other hand, WB-shear force did not distinguishable after 3 d. Collectively, it appeared that feed restriction from a day before slaughter could produce more a desirable meat quality at the time of consuming. However, the limited effect of animal handling and chilling rate on meat quality is not necessarily to extend to that these do not affect pork quality, as that largely depends on experimental design.

The aim of this study was to examine the relationship between dietary variables and the prevalence of insulin resistance (IR) in middle-aged Korean adults using data from the 2007-2009 Korea National Health and Nutrition Examination Survey. Because IR is closely linked with metabolic syndrome, subjects were divided into three groups according to symptoms of metabolic syndrome: the 'Normal group' without any symptoms, the 'Risk group' with one or two symptoms, and the Metabolic syndrome (MetS) group' with three or more symptoms. Subjects between the ages of 30 and 65 years with no prior diagnosis or treatment for diabetes, hypertension, or dyslipidemia were selected. The number of subjects per group was as follows: 2,085 adults in the Normal group, 3,699 adults in the Risk group, and 1,160 adults in the MetS group. Metabolic syndrome was defined according to Adult Treatment Panel III criteria with modified waist circumference cutoff values (men ${\geq}$ 90 cm, women ${\geq}$ 85 cm). Subjects with HOMA-IR > 2.0 were classified as IR. Homeostasis Model Assessment of Insulin Resistance (HOMA-IR) was calculated using the following formula: (fasting plasma glucose ${\times}$ fasting plasma insulin)/22.5. Nutrients and food groups intake were obtained from a single 24-hour recall. Subjects with IR in the Normal group were more obese and less physically active than non-IR subjects. In the MetS group, subjects with IR were more obese and had a lower prevalence of smoking and drinking, compared with non-IR subjects. Men with IR in the Normal group had a tendency to consume more oils and sugars than non-IR men, while women with IR in the same group had higher intake of carbohydrate, dietary glycemic index, and dietary glycemic load than non-IR women. Women with IR in the Risk group had lower energy intake but higher intake of oils and sugars than non-IR women. In the MetS group, consumption of fruits was higher in subjects with IR than in non-IR subjects. In conclusion, findings of this study suggest that dietary carbohydrate intake, including glycemic index, may be associated with IR in healthy women. Further research in prospective cohort studies in order to examine the effects of dietary carbohydrate on IR incidence will be necessary.

To control blood glucose level as close to normal is a major goal of treatment of diabetes mellitus. Hyperglycemia and hyperlipidemia are the major risk factors for cardiovascular complications, the major cause of immature death among the patients with type 2 diabetes. The purpose of this study is to determine the hypoglycemic and hypolipidemic effects of Salicornia herbacea in animal model of type 2 diabetes and to investigate the possible mechanisms for the beneficial effects of S. herbacea. S. herbacea was extracted with 70% ethanol and desalted with 100% ethanol. Three week-old db/db mice (C57BL/KsJ, n=16) were fed AIN-93G semipurified diet or diet containing 1% desalted ethanol extract of S. herbacea for 6 weeks after 1 week of adaptation. Fasting plasma glucose, triglyceride, and total cholesterol were measured by enzymatic methods and blood glycated hemoglobin ($HbA_{1C}$) by the chromatographic method. Body weight and food intake of S. herbacea group were not significantly different from those of the control group. Fasting plasma glucose and blood glycated hemoglobin levels tended to be lowered by S. herbacea treatment. Consumption of S. herbacea extract significantly decreased plasma triglyceride and cholesterol levels (p<0.05). The inhibition of S. herbacea extract against yeast ${\alpha}$-glucosidase was 31.9% of that of acarbose at the concentration of 0.5 mg/mL in vitro. The inhibitory activity of ethanol extract of S. herbacea against porcine pancreatic lipase was 59.0% of that of orlistat at the concentration of 0.25 mg/mL in vitro. Thus, these results suggest that S. herbacea could be effective in controlling hyperlipidemia by inhibition of pancreatic lipase in animal model of type 2 diabetes.

Objective : Diabetic gastroparesis is a complication that is defined as delayed gastric emptying and upper gastrointestinal symptoms and often occurs in long-standing diabetic patients. Bojungikgi-tang (BJT) is a traditional oriental herbal formula that has long been used for the treatment of digestive disorders. The purpose of this study was to investigate the effects of BJT on streptozotocin (STZ)-induced diabetic gastroparesis rat model. Methods : Sprague-Dawley (SD) male rats (250-270g) were divided into 13 groups including normal group, STZ-induced diabetic control group, BJT diet (7 various concentrations), and insulin-, glibenclamide-, metformin-treated group were used for the experiments for the comparison. Diabetic gastroparesis was induced by intraperitoneal injection of STZ. The water intake, food intake, body weights and fasting blood glucose levels were measured. After 4 weeks the animals were sacrificed and gastrin, leptin, insulin, hemoglobin A1C (HbA1c), lactate, lactate dehydrogenase (LDH), bilirubin, creatinine, albumin and lipid levels were evaluated. Results : Intraperitoneal injection of BJT for 4 weeks resulted in increased levels of gastrin in blood and decreased leptin and lactate concentration in STZ-induced diabetic gastroparesis rat model. BJT did not affect insulin, fasting glucose, HbA1c, and lipid levels in STZ-induced diabetic gastroparesis rat model. Conclusion : These results indicated that BJT would have protect effect on diabetic gastroparesis through the improvement effect of gastric motility and fatigue syndrome in STZ-induced diabetic rats. This study shows that BJT might be effective for treatment of diabetes and its complications such as gastroparesis.

The purpose of this study was to assess the effects of mulberry leaf extract supplement on blood glucose, glycated hemoglobin ($HbA_{1C}$) and serum lipids in type II diabetic patients, and also to assess safety in liver function after mulberry leaf extract supplement. The study was a randomized placebo-controlled trial and total 23 type II diabetic patients were divided into a MLE group taking 1,000 mg mulberry leaf extract supplement per day as experimental group and a placebo group taking 1,000 mg cellulose Powder supplement per day for 12 weeks. After 2 weeks of wash-out period, fasting blood glucose, $HbA_{1C}$, serum lipid levels and liver function test were analyzed before and after treatment of 12 weeks. The general baseline characteristics, nutrient intake and life style factors of study subjects were similar between two groups during intervention. The concentrations of fasting blood glucose and $HbA_{1C}$ (p<0.05) decreased significantly after mulberry leaf extract supplement in MLE group, while there were no changes found in placebo group. We also found it showed that mulberry leaf extract supplement for 12 weeks decreased significantly (p<0.05) the fasting blood glucose in poor fasting blood glucose group and $HbA_{1C}$ concentration in poor $HbA_{1C}$ group. The concentrations of LDL-cholesterol (p<0.05) and triglyceride (p<0.01) decreased significantly in MLE group after 12 weeks of taking the supplement, while there were no changes found in placebo group. The mulberry leaf extract supplement for 12 weeks didn't show hepatotoxicity. These results suggested that mulberry leaf extract supplement could be effective in improving fasting blood glucose and $HbA_{1C}$ levels in the diabetic patients, specially having high concentrations of fasting blood glucose and $HbA_{1C}$ among type II diabetic patients.

Finding alternative feeds, such as sesame hulls and Prosopis juliflora species can attenuate difficulties of feed shortage and reduce the cost of animal feed in arid and semi-arid countries. Thirty-two Black male kids with similar initial weights (BW = $16.7{\pm}0.80\;kg$) and $120{\pm}5\;d$ of age, were used to evaluate the effect of replacing barley grains and soybean meal with Prosopis juliflora pods (PJP) and sesame hulls (SH) on growth performance, digestibility and carcass and meat characteristics. Kids were equally divided into four dietary treatment groups for an 84-d fattening period. Treatment diets had similar crude protein (CP) and metabolizable energy (ME). The treatment groups were: (T1) no PJP nor SH, (T2) 10% PJP and 20% SH, (T3) 15% PJP and 15% SH, and (T4) 20% PJP and 10% SH. A tendency was detected (p<0.08) for dry matter (DM), crude protein (CP), organic matter (OM) and neutral detergent fiber (NDF) intakes that were greater for T2 than T3 and T4 while T1 was not different from all other treatment groups. Ether extract (EE) intake was the greatest (p<0.05) for T2 and the lowest for T1. Acid detergent fiber (ADF) intake was greater (p<0.05) for T2 than T1 while T3 and T4 were intermediate. Final live weight, average daily gain (ADG) and feed conversion ratio (FCR) were comparable among different treatment groups. Digestibility of DM, OM, CP, NDF and ADF were similar among all treatment groups, however, EE digestibility was the lowest (p<0.05) for T1 when compared to other treatments. In addition, nitrogen intake, nitrogen in urine and retained and retention percentages were similar among all treatment groups. However, N loss in feces was higher (p<0.05) for T2 than T3 and T4 while T1 was intermediate. No differences were observed among treatment groups with respect to fasting live weight, hot and cold carcass weights, dressing-out percentages, mesenteric fat, visceral organs, carcass cuts percentages and carcass linear dimensions. No differences were also observed for dissected loin, leg, rack and shoulder tissues except in the total bone % for loin cuts and in the meat to bone ratio for rack cuts. T3 has the greatest total bone % and the lowest meat to bone ratio when compared to all other treatment groups. No differences were observed between treatment groups in all quality characteristics of the longissimus muscle. The present study demonstrates the potential of using PJP and SH for growing kids without adverse effects on growth performance, carcass characteristics and meat quality.
