Increased Risk

Adults born preterm are at increased risk of impaired glucose tolerance and diabetes. Late gestation fetuses exposed to high blood glucose concentration also are at increased risk of impaired glucose tolerance as adults. Preterm babies commonly become hyperglycemic and are thus exposed to high blood glucose concentration at an equivalent stage of pancreatic maturation. It is not known whether preterm birth itself, or complications of prematurity, such as hyperglycemia, alter later pancreatic function. To distinguish these, we made singleton preterm lambs hyperglycemic (HYPER) for 12 days after birth with a dextrose infusion and compared them with vehicle-treated preterm and term controls and with HYPER lambs made normoglycemic with an insulin infusion. Preterm birth reduced β-cell mass, apparent by 4 weeks after term and persisting to adulthood (12 mo), and was associated with reduced insulin secretion at 4 months (juvenile) and reduced insulin mRNA expression in adulthood. Hyperglycemia in preterm lambs further down-regulated key pancreatic gene expression in adulthood. These findings indicate that reduced β-cell mass after preterm birth may be an important factor in increased risk of diabetes after preterm birth and may be exacerbated by postnatal hyperglycemia.

Protein Energy

1. Young Wistar rats were used as an experimental model to determine the effects of protein-energy malnutrition on glucose tolerance and insulin release. 2. Malnourished rats presented some of the features commonly found in human protein-energy malnutrition, such as failure to gain weight, hypoalbuminaemia, fatty infiltration of the liver and intolerance of oral and intravenous glucose loads. 3. The rate of disappearance of glucose from the gut lumen was greater in the malnourished rats but there was no significant difference in portal blood glucose concentration between normal and malnourished rats 5 and 10 min after an oral glucose load. 4. Insulin resistance was not thought to be the cause of the glucose intolerance in the malnourished animals since these rats had a low fasting plasma insulin concentration with a normal fasting blood glucose concentration and no impairment in their hypoglycaemic response to exogenous insulin administration. Furthermore, fasting malnourished rats were unable to correct the insulin-induced hypoglycaemia despite high concentrations of hepatic glycogen. 5. Malnourished rats had lower peak plasma insulin concentrations than normal control animals after provocation with oral and intravenous glucose, intravenous tolbutamide and intravenous glucose plus aminophyllin. This was not due to a reduction in the insulin content of the pancreas or potassium deficiency. Healthy weanling rats, like the older malnourished rats, had a diminished insulin response to intravenous glucose and intravenous tolbutamide. However, their insulin response to stimulation with intravenous glucose plus aminophyllin far exceeded that of the malnourished rats. Thus the impairment of insulin release demonstrated in the malnourished rats cannot be ascribed to a ‘functional immaturity’ of the pancreas.

Meal Replacements

The purpose of this study was to investigate whether the genetic polymorphisms of the uncoupling protein 1 (UCP1) and beta 3 adrenergic receptor (β3-AR) were associated with differences in weight loss and lipid profiles in obese premenopausal women exposed to low-calorie meal replacements over a period of six weeks. Forty women between the ages of 20 and 35 were randomly divided into two groups, each of which consumed one of two low-calorie meal replacements containing either white rice or mixed rice. Although body weight, body mass index (BMI), blood glucose concentration, triglycerides, total cholesterol (TC), and high-density lipoprotein cholesterol (HDL-C) were not significantly different by the UCP1 genotype in the white rice group, there were significant differences in body weight (p = 0.041), BMI (p = 0.027), and blood glucose concentration (p = 0.047) between carriers and non-carriers of the G allele in the mixed rice group after the six-week meal replacement intervention. The β3-AR polymorphism showed no apparent affect on these parameters. Dietary fiber affects weight gain since it is closely related with absorption of nutrients. As a result, the AA type UCP1 genotype produced significant weight loss in the mixed rice group, but not in the white rice group.

Insulin Levels

Eight male patients with cystic fibrosis, normal nutrition, normal physical activity, relatively mild pulmonary disease, no evidence of liver disease and no family history of diabetes mellitus underwent a series of carbohydrate tolerance tests in comparison with a group of 18 normal male subjects matched for age and body weight. Compared with the normal group, the patients with cystic fibrosis had significantly impaired glucose tolerance and significantly lower serum immunoreactive insulin levels during oral and intravenous glucose tolerance tests; serum insulin levels were also significantly lower after intravenous administration of tolbutamide in the patients with cystic fibrosis, but the reduction in blood glucose concentration in each group was not significantly different. During an intravenous insulin test, the decrease in blood glucose concentration was the same for both groups, in spite of significantly lower serum insulin levels in the patients with cystic fibrosis. The percentage fall in plasma free fatty acids was at least as great in the patients with cystic fibrosis as in normals during the test procedures, while a significant decrease in plasma alpha-amino nitrogen after intravenously administered insulin was seen only in the patients with cystic fibrosis. These studies suggest that the carbohydrate intolerance of cystic fibrosis is consequent upon an impaired insulin response to glucose, but that this insulin deficiency is partly compensated for by increased peripheral tissue sensitivity to insulin.

Diabetic nephropathy (DN) is a common complication of diabetes and it is related to irreversible kidney damages and chronic renal failure. Impaired glucose tolerance (IGT) is an early stage in the development of diabetes and DN. Early detection of IGT and treatment of its associated early kidney damage can effectively prevent the development of DN. In this paper, the influence of dihydromyricetin (DHM) on lowering blood glucose concentration and reducing early kidney damage in IGT rats was studied. Animal model of IGT rats was built by two week intragastric injection of D-galactose and treated with eight weeks of intragastric injection of DHM at two dose levels. The concentrations of fasting blood glucose (FBG), two-hour postprandial blood glucose (2hBG), insulin levels, contents of microalbuminuia (mAlb) and blood urea nitrogen (BUN), and activities of lactate dehydrogenase (LDH) in kidney were analysed and compared with those in control groups. Experimental results indicated that DHM treatment can significantly lower the levels of two-hour postprandial blood glucose and insulin, decrease the content of mAlb and the activities of LDH in kidney, but does not influence the level of BUN. The study suggested that DHM can effectively improve the states of IGT rats and provide a protective effect against early kidney damage.
