To better understand the molecular mechanisms for hyperglycemia-induced proatherogenic changes in endothelial cells, the effect of high glucose on activation of members of the mitogen-activated protein kinase (MAPK) family, including c-Jun NH(2)-terminal kinase (JNK), extracellular signal-regulated kinase (ERK)-1, -2, and -5, and p38 kinase, was examined in bovine pulmonary artery endothelial c...

This study assessed the site of increased glucose uptake resulting from insulin inhalation, quantified its effect under steady-state glucose concentrations, and identified the time to onset of effect. Human insulin was administered to 13 beagles via inhalation (Exubera [insulin human (rDNA origin)] Inhalation Powder; n = 7) or infusion into the inferior vena cava (Humulin R; n = 6) using an alg...

the effects of aluminium and aluminium-citrate on some serum parameters related to carbohydrate metabolism in male wistar rats were investigated. daily intraperitoneal administrations of 1 mg/kg body weight of aluminium or aluminiumcitrate (1: 1) for 50 days led to the elevation of serum insulin by 24 or 40 percent respectively, with the concomitant decrease in serum glucose concentrations by 1...

The aim of the present work was to test the effect of acute in vivo alcohol administration (180-190 mg/dl plasma for 3 h) on glucose utilization by tissues under basal conditions or after a hyperinsulinemic (100-130 microU/ml) euglycemic clamp in fasted rats. In vivo glucose use by individual tissues was assessed by the tracer 2-deoxy-D-glucose technique. Alcohol administration to saline-infuse...

Neutrophils are phagocytic cells of the innate immune system that use a combination of reactive oxygen species and anti-microbial toxins to kill and destroy ingested micro-organisms. Once they have performed their function, neutrophils die by apoptosis, which is important for the effective resolution of the inflammatory response. Both glucose and glutamine are important fuels for neutrophils, y...

The antilipolytic effect of insulin was studied in 9 obese and 10 age- and sex-matched subjects of normal weight. Isolated fat cells were taken before and 1 h after an 100 g oral glucose load. Insulin inhibition of basal and isoprenaline-induced rates of lipolysis were determined by using a sensitive bioluminescent glycerol assay. When compared with the controls, the obese group showed a lower ...

OBJECTIVE: Since bread is the main source of food in Iran, we aimed to assess the effect of four types of Iranian breads on metabolic and cardiovascular responses before and during 15, 30, 60, 90, 120 and 180 minutes of consumption in type 2 diabetic patients. MATERIALS AND METHODS: Ten type 2 diabetic patients (6 women and 4 men) with mean age of 51 ± 9.8 years and mean BMI of 31.9 ± 1.19 kg/...

abstract          background and objective: according to iranian, asian, indian, and chinese traditional medicine, basil is used in the treatment of different diseases. in this study, the effect of basil on lowering the blood glucose was examined in healthy and diabetic rats.         methods: sixty wistar rats were divided into a control group(n=10), a basil receiving group (n=20) and a diabeti...
