An Experiment was conducted to evaluate the effects of dietary excessive chromium picolinate on growth performance, nutrient utilizability and the content of serum cholesterol, HDL cholesterol, glucose, triglyceride and non-esterified fatty acid in broiler chicks. Experimental diets based on corn-soybean meal were supplemented at 0, 800, 1,600 and 2,400 ppb chromium in the form of chromium picolinate. Each treatment had six replicates of six female chicks each (average initial weight=45.6 g). Experimental period lasted for six weeks. Excessive supplementation of chromium as chromium picolinate had no effect on body weight gain, feed intake, feed conversion and nutrient utilizability of broiler chicks. Mortality was improved with a supplementation of chromium (p < 0.05). However, serum glucose decreased as chromium level increased (p < 0.05). Up to 2,400 ppb chromium as chromium picolinate, signs of toxicity were not noticed in this study.

Ginseng has been widely used in the Oriental world for more than 2,000 years. Its chemical and pharmacological studies have been published by many investigators of many countries. But its clinical studies have not been performed in satsifactory amount. This study was carried out to evaluate the effect of ginsenoside-triol on the postoperative recovery in 120 cases of gynecological laparotomies. Daily dose of 0.23 gram of ginsenoside-triol was administered orally for three weeks after surgery to 60 cases, and placebo to 60 cases as control. Hemoglobin, hematocrit, leukocyte count, serum total protein, albumin, cholesterol and glucose were studied at pre- and postadministration. At the same time, body weight, blood pressure and subjective symptoms such as appetite, bowel movement and digestion were checked. The results obtained were summarized as follows: 1) The side effect was nil. 2) Hemoglobin and hematocrit Were more increased in treated group than in control group, but the changes were not significant. 3) Serum total protein was more significantly increased in treated group than in control group. 4) Serum cholesterol was significantly less increased in treated group than in control group. 5) Serum glucose level was significantly decreased in both groups, more significantly in control group. 6) Body weight was significantly increased in treated group.

This study was to investigate the risk factors for the development of diabetes mellitus on healthy offsprings of Korea non-insulin dependent diabetes mellitus(NIDDM) patients. Forty four offsprings who have at least 1 parent with NIDDM and age, sex and body mass index(BMI) matched forty four healthy control subjects were collected for this study. BMI, skinfold thickness, waist/hip circumference ratio(WHR), fasting blood glucose, serum insulin, serum lipid profile, nutrient intakes and food behaviors were measured. There were no significant difference in BMI, WHR, fasting blood glucose, insulin, total cholesterol, triglyceride and daily nutrients intake between offsprings and controls. But skinfold thickness, LDL-cholesterol level and sweety food eating frequency were significantly higher in male offsprings than in male controls. And HDL-cholesterol was significantly lower in male offsprings than in male controls. Although there were no significant difference, offsprings had a overeating habit and ate more confectionery and greasy food than controls.

This study was to investigate the effect on weight control and changes in serum glucose, total protein , GPT, GOT , cholesterol, triglyceride, calcium, and phosphorus contents of seventeen overweight female college students during experimental periods [before grape diet(0 day-, after grape diet (3 day), after control diet(3 day), after normal diet(30 day)]. The mean weight, height , BMI, and Rohrer index of the subjects at the onset of the study was 58.91$\pm$5.22kg, 159.94$\pm$6.01cm, 22.96$\pm$1.17, and 20.06$\pm$1.48 respectively. During the study subjects, conducted grape diets, control diets, and normal diets to control their weight. They analyzed their changes in anthrophometric variables. The mean weight was significantly decreased from 58.29$\pm$7.85kg to 57.2$\pm$8.23kg after normal diet(p<0.05). Therefore BMI (body mass index) and Rohrer index was also significantly decreased after experimental periods. The analysis of dietary intake showed that the grape diet induced unbalanced low nutrient intake, but the intake of total calories and other nutrients were almost recovered their onset of the study during control and normal diets. The concentration of serum glucose, cholesterol, triglyceride GOT, and GTP were significantly(p<0.05) decreased and significantly(p<0.05) increased again during experimental periods. Calcium concentrations were not affected by grape diet, but phosphorus concentration was significantly reduced after grape and control diet.

This study was performed to investigate the effects of puffed-red ginseng (PRG) powder and drink on blood glucose level and serum lipid profile in streptozotocin (STZ)-induced diabetic rats. For the experimental design, STZ-induced diabetic rats were fed PRG powder-supplemented diets (0.3%, 0.6%) and diluted drinks (0.14%, 0.28%) for 6 weeks. Concentrations of blood glucose during the experimental period decreased to 18.3 mg/dL in the 0.6% PRG diet group and 15.1 mg/dL in the 0.14% PRG drink group. Average reduction rate of blood glucose in the last week compared to reference blood glucose concentration decreased by 19.2% (A group), 37.4% (B group), 18.7% (C group), and 17.3% (D group) in the PRG treatment groups, respectively. These results indicate that PRG affects blood glucose via ginseng saponins administered in diet or drinking water, thereby suggesting that PRG has the ability to prevent increasing blood glucose in mild-induced diabetic rats.

Objective : This study was designed to investigate anti-diabetic effects of fermented soy bean extract with herbal medicines (Godjang) in diabetic rat models induced by streptozotocin (STZ) injection. Method : Changes in body weight, drinking water, and food intake were observed for 4 weeks before and after induction of diabetes mellitus in rats. The anti-diabetic capacity of Godjang was analyzed by fasting blood glucose (FBG) every week. Also, after 4 weeks of administration, the oral glucose tolerance test (OGTT) was performed, and then blood levels of insulin were checked. And serum levels of total cholesterol and triglycerides were determined. Histomorphological changes of liver, kidney and pancreatic tissues were also observed in STZ-induced diabetic rats and Godjang administered rats. Result : In Godjang administered group, body weight and water intake were more lower than that of STZ-induced diabetic rats. FBG was decreased in the Godjang administered group than STZ-induced diabetic group. According to OGTT, blood glucose levels at 30 minutes and 60 minutes significantly decreased in Godjang administered group than in STZ-induced diabetic control group. Administration of Godjang extract for 4W significantly decreased levels of serum glucose, total cholesterol (TC), triglycerides (TG) in diabetic rats. In histomorphological analysis of kidney, liver, Godjang administrated groups showed the inhibition of pathological damage. Conclusion : These results suggest that Godjang extract has an anti-diabetic action through decrease in serum glucose, TC, TG levels and recovery of the morphological changes in kidney and liver in STZ-induced diabetic rats.

Objectives : Onion (AlliumcepaL.) is one of the richest sources of flavonoids in human diet. In this study, we studied the effects of onion peel water extract (OPE) on the blood lipid profiles and glucose in rats. Methods : The experimental groups were divided with 5 groups (n = 6) of SD rats: normal diet + distilled water (NC), high-fat diet + Quercetin (PC), high-fat diet + onion peel water extract 4 mg/kg (OPE-4), high-fat diet + onion peel water extract 20 mg/kg (OPE-20), high-fat diet + onion peel water extract 100 mg/kg (OPE-100). Results : The liver fat showed significantly lower weights and size in the OPE-100 group as compared with NC group (p<0.05), The epididymal fat and retroperitoneal fat showed significantly lower weights and sizes in the OPE-4 and OPE-20 group as compared with NC group (p<0.05). The serum levels of total cholesterol, LDL cholesterol and triglyceride were significantly lower in the OPE-4 and OPE-20 group as compared with NC group (p<0.05). The OPE-4 and OPE-20 group showed higher HDL cholesterol concentration than NC group (p<0.05). Atherogenic index of OPE-4 and OPE-20 group was significantly lower in as compared with NC group (p<0.05). The serum levels of glucose significantly lower in the OPE-20 group as compared with NC group (p<0.05). Conclusions : In these results, we suggests that onion peel water extracts supplementation can reduces the serum lipid components and improves the lipid metabolism in hyperlipidemic SD rat induced with a high-fat diet.

In recent years, the prevalence of type 2 diabetes mellitus has dramatically increased in Korea as the diet has rapidly become westernized. We determined the effect of long-term cola intakes on glucose metabolism and oxidative stress in weanling male Sprague Dawley rats consuming a moderate fat diet Thirty male rats, born from 6 female rats, were randomized into cola or water drinking groups. For 28 weeks, all rats were provided with an ad lib solid diet having 33 percent of its metabolisable energy as fat In addition, rats of the cola group were provided with ad lib cola instead of water. The daily total caloric intake did not differ between groups. The rats in the cola group consumed a higher proportion of carbohydrates, and their mean body weight and fasting serum insulin level were lower than that of the control group. Whole-body glucose disposal rates measured by an euglycemic hyperinsulinemic clamp were higher in the cola group. However, lipid peroxide levels in kidney tissue were higher in the cola group than in the control group. Superoxide dismutase activity in kidney tissues was lower in the cola group compared to the control group, while glutathion peroxidase and catalase activities were not significantly different between the two groups. In conclusion, long-term cola intakes decreased insulin resistance, but increased oxidative stress in kidney tissue due to decreased SOD activities, which may lead to kidney damage. Thus, moderate changes in insulin resistance may not affect the status of oxidative stress, and vice versa.

The effects of Aegle marmelos (Rutaceae) leaf, Emblica officinalis (Euphorbiaceae) fruit and Ocimum sanctum. (Labiateae) leaf extracts were studied in L-thyroxine (0.5 mg/kg) induced hyperthyroidic mice. Separately combined effects of these three plant extracts and of a commonly used antithyroidic drug, Propyl thiouracil (PTU) were investigated for comparison. Serum concentration of thyroxine $(T_4)$, triiodothyronine $(T_3)$, glucose and the activity of hepatic Glucose 6-Phosphatase (G-6-Pase) were considered as main parameters. Hepatic lipid peroxidation (LPO), superoxide dismutase (SOD) and Catalase (CAT) activities were also studied to reveal the toxic effect of the plant extracts, if any. While exogenous $T_4$ enhanced serum concentration of $T_4$, $T_3$, glucose and the activity of hepatic G-6-Pase, a simultaneous administration of either A. marmelos leaf (1.0 mg/kg), E. officinalis fruit( 30 mg/kg) and O. sanctum leaf (50 mg/kg) extracts, to hyperthyroidic animals decreased all these parameters. However, the effects were more pronounced, as nearly normal thyroid function and serum glucose concentration were exhibited when all three plant extracts were administered together. A decrease in LPO and a concomitant increase in SOD and the CAT activities indicated the safe and antiperoxidative nature of the plant extracts, administered either alone or in combination. Our findings reveal that the three test plant materials exhibit synergistic effects without any hepatotoxicity, suggesting their potential use in the amelioration of hyperthyroidism and/ or hyperglycaemia.
