  • Two experiments were conducted to examine the effect of graded levels of dietary chromium and leucine, and different fat sources on performance and body composition of broiler chickens. The results showed that chromium picolinate at 0.5 ppm significantly (p<0.05) lowered the carcass fat level. Gut weight and carcass water content were increased as a result of chromium treatment. Body weight, plucked weight, carcass weight, abdominal fat pad weight, breast yield and feed efficiency were unaffected by chromium treatment. Leucine did not interact with chromium to effect lean growth. Dietary leucine above the recommended maintenance level (1.2% of diet) markedly (p<0.001) reduced the breast muscle yield. The addition of fish oil to broiler diets reduced (p<0.05) the abdominal fat pad weights compared to birds on linseed diets. Fish oil is believed to improve lean growth through the effects of long chain polyunsaturated fatty acids in lowering the very low-density lipoprotein levels and triglyceride in the blood, in the meantime increasing glucose uptake into the muscle tissue in blood and by minimizing the negative impact of the immune system on protein breakdown. The amount of fat in the diet (2% or 4%) did not affect body composition.

  • Curcuma longa belongs to the family Zingiberaceae and can be found in the tropical and subtropical regions of the world. It is widely used in Asiatic countries, especially India and South East Asia where it is cultivated commercially as a condiment. Its rhizomes exhibit anti-inflammatory, anti-human immunodeficiency virus, anti-bacterial, antioxidant effects, nematocidal activities, antiproliferative and antiangiogenic activities and are of pharmaceutical importance. Another relevant medicinal property exhibited by it is antidiabetic property which is reviewed here. Studies on the efficacy of crude C.longa extracts against type 2 diabetes in murine models reveal that it demonstrates a hypoglycemic effect by lowering the blood glucose levels under in vivo conditions. Clinical studies have revealed the safety of curucmin (major principle component exhibiting pharmaceutical properties from C.longa) on humans but with very low bioavailability. In view of its effective hypoglycemic effect and its low bioavailability, further studies are needed for the characterization of the bioactive principles and formulating the development of C.longa extracts as a novel anti-diabetic therapeutic agent.

  • Acute (24 h) and chronic (90 days) oral toxicity studies on the ethanol extract of Trigonella foenumgraecum Leguminosae (L.) seeds were carried out. Acute dosages were 0.5, 1.0 and 3 g/kg while chronic dosage was 100 mg/kg per day of the extract. All morphological, biochemical, haematological and spermatogenic changes, in addition to mortality, body weight changes and any change in vital organs were recorded. Histopathological investigations were done on vital organs. Growth arrest in the treated animals was observed. The treated mice gained no significant weight during chronic treatment while there was a significant gain in body weight of the control group mice. Biochemical studies revealed a significant decrease in blood sugar levels of fenugreek treatment groups while haematological parameters remained comparable to the control. In the treatment, male group there was a significant decrease in weight of testes as compared to the control. There was a marginal weight gain in kidney weight of mice after chronic treatment as compared to the control. Fenugreek chronic treatment caused a highly significant spermatotoxic effects in male mice.

  • Dietary fiber naturally present in various sources of cereals, legumes, fruits and vegetables plays a physiological role in human health, such as lowering cholesterol and blood pressure, improving blood glucose control in diabetes, helping with weight loss and management, and reducing cancer risk. In addition, dietary fibers have has been added as a functional food ingredient to food products to provide water-holding capacity, viscosity, gel-forming ability, and fat-binding capacity to food products. These beneficial characteristics of dietary fiber components can improve the image of meat products to be healthy and functional food products. This article reviews the concept and current definition of dietary fibers in food products along with their health benefits and functional characteristics. Dietary fibers from different sources like cereals, legumes, fruits, and vegetables and soluble dietary fibers have been applied as functional ingredients to various types of meat products, such as beef patties, ground beef and pork, pork and chicken sausages, meatballs, and jerky etc. Based on the application of dietary fibers to different types of meat products, possible future characteristics in selecting appropriate dietary fiber ingredients and their proper incorporation are explored to develop and produce healthy and functional meat products with high dietary fiber contents.

  • The aim of this study was to investigate the effects of isolated protein from white rice on lipid metabolism in a hypercholesterolemic animal model. Male Sprague-Dawley rats were divided into three groups and fed either a normal diet or a high-cholesterol diet (HCD) containing either casein or isolated rice protein for 4 weeks. Compared with rats fed a HCD with casein, the total cholesterol (TC) level in the plasma was significantly reduced in the rats fed rice protein. However, no significant differences were observed in the triglycerides, high-density lipoprotein (HDL), and glucose levels among the experimental groups. Hepatic total lipids and TC levels were significantly decreased by supplementation with rice protein. In addition, rice protein significantly increased the levels of TC and bile acids in the feces. These results suggest that rice protein may improve HCD-induced hypercholesterolemia by enhancing fecal excretion of cholesterol.

  • As the average span of human life is continuously increasing, especially the old aged groups, are suffering from various chronic and critical diseases e.g. cardiovascular diseases, coronary heart disease, diabetes, atherosclerosis and alzheimer's etc. However, effective and safe treatment methods have not yet been investigated threathening old aged groups. This research was planned to isolate compounds with the therapeutic potential for the above mentioned chronic diseases from the mulberry leaves. Biological screenings were carried out for the following categories; anti-atherogenic, anti-diabetic and antihypertensive effects. The results were as follows; Mulberry leaves, 20% $\alpha$-treated Gaelyrangppong showed significant 81% of blood glucose lowering effects in alloxan-induced hyperglycemic mice. Particularly, butanol-soluble fractions of mulberry leaves showed the more significant hypoglycemic activity than other fractions in alloxan induced hyperhlycemic mice. Also in the group given 1g/kg doses of extract of mulberry leaves, total cholesterol level was decreased significantly by as much as 49% in hyperlipidemia-induced rats. In Mulberry leaves post-treated group, the atheroscelosis index, HDL-cholesterol/Total-cholesterol, was increased significantly by as much as 91%.

  • Microneedles (MNs) are being developed to overcome the limitations of the conventional hypodermic needle, e.g. the injection pain. In this study, we conducted an analysis of clinical pain and bleeding at the site of MN insertion and evaluated the insulin pharmacodynamic profile compared with parameters obtained with a conventional pen needle. MN insertion into the skin of 25 healthy adults or 15 patients with type 2 diabetes (T2D) revealed significantly less pain relative to a conventional hypodermic pen needle, thus reducing pain scores from $2.1{\pm}1.9$ to $21.3{\pm}1.4$ ($mean{\pm}standard$ deviation [SD]). Besides, no bleeding was observed when the MN was used. In the insulin pharmacodynamic assay, no significant differences were observed in the blood glucose-lowering effect between the pen needle and MN. Based on these results, the MN is expected to be a good substitute for conventional hypodermic pen needles and improve the quality of life of patients by significantly reducing the pain associated with insulin treatment.

  • Estrogen is crucial in regulating food intake, energy expenditure, glucose metabolism, and lipid metabolism. During menopause, the decline in estrogen levels predisposes women to weight gain, abdominal obesity, insulin resistance, type 2 diabetes, hypertension, and cardiovascular disease (CVD). Menopausal hormone therapy (MHT) prevents weight gain, improves lipid metabolism by lowering low-density lipoprotein cholesterol while raising high-density lipoprotein cholesterol, and delays the onset of type 2 diabetes in menopausal women. The effect of MHT on CVD in menopausal women remains controversial. The Women's Health Initiative study was terminated prematurely after it revealed that hormone administration increased the risk of myocardial infarction, stroke, and thromboembolism. However, some studies have found that MHT had no effect or decreased the risk of CVD. The inconsistent results were likely due to multiple factors, including the timing of hormone therapy initiation, duration of therapy, type and dosage, and presence or absence of CVD risk factors at the start of treatment. Despite its benefits in terms of managing weight gain and reducing the risk of type 2 diabetes, dyslipidemia, and CVD associated with obesity, it is not recommended as the primary therapy for weight loss or diabetes prevention. MHT is primarily indicated for postmenopausal women, who are likely to benefit from its potential to prevent weight gain and improve lipid metabolism.

  • This study was designed to examine the effects of diets containing different levels of seeds of Benincasa hispida (wax-gourd)on plasma glucose, insulin levels and lipid profiles in streptozotocin (STZ)-induced diabetic rats. Sprague-Dawley rats were induced diabetes mellitus by STZ injection (45 mg/kg) into the tail vein and were divide into 4 groups: normal, STZ-control, two experimental groups. Normal and STZ-control groups were fed an AIN-93 diet and 2 experi-mental groups were fed a modified diet containing 2.5% and 5.0% of wax gourd seed powder for 4 weeks. The weight gain and feed efficiency ratio in 5.0% seed groups were higher than in STZ-control group. A significant lowering effects of plasma glucose levels were observed in the wax gourd seed 2.5% and 5.0 groups. The plasma insulin level did not differ after treatment with wax gourd seed in experimental rats. The intake of 2.5% wax gourd seed did not result in sig-nificant change in plasma cholesterol levels compared to diabetic control group. The intake of 2.5% wax gourd seeds had normalized the increased levels of plasma triglyceride and free fatty acids after 4 weeks. In 5% wax gourd seed group, cholesterol, triglyceride and free fatty acid levels were elevated compared to 2.5% wax gourd seed group. The results of the present study indicate that 2.5% wax gourd seed group would be more effective to control the diabetes than 5% wax gourd seed group.
