Aims: Arganimide A (4,4-dihydroxy-3,3-imino-di-benzoic acid) is a compound belonging to a family of aminophenolics found in fruit of Argania spinosa. The purpose of this study was to investigate the glucose and lipid lowering activity of Arganimide A (ARG A). Methods: The effect of a single dose and daily oral administration of Arganimide A (ARG A) on blood glucose levels and plasma lipid profile was tested in normal and streptozotocin (STZ) diabetic rats at a dose of 2 mg/kg body weight. Results: Single oral administration of ARG A reduced blood glucose levels from 26.50±0.61 mmol/L to 14.27±0.73 mmol/L (p<0.0001) six hours after administration in STZ diabetic rats. Furthermore, blood glucose levels were decreased from 5.35±0.30 mmol/L to 3.57±0.17 mmol/L (p<0.0001) and from 26.50±0.61 mmol/L to 3.67±0.29 mmol/L (p<0.0001) in normal and STZ diabetic rats, respectively, after seven days of treatment. Moreover, no significant changes in body weight in normal and STZ rats were shown. According to the lipid profile, the plasma triglycerides levels were decreased significantly in diabetic rats after seven days of ARG treatment (p<0.05). Moreover, seven days of ARG A treatment decreased significantly the plasma cholesterol concentrations (p<0.001). Conclusion: ARG A possesses glucose and lipid-lowering activity in diabetic rats and this natural compound may be beneficial in the treatment of diabetes.

Insulin Responses

Insulin secretion is impaired in type 2 diabetes (T2D). The insulin and glucose responses to central autonomic activation induced by excitation of brain medullary TRH receptors were studied in T2D Goto-Kakizaki (GK) rats. Blood glucose levels in normally fed, pentobarbital-anesthetized GK and nondiabetic Wistar rats were 193 and 119 mg/100 ml in males and 214 and 131 mg/100 ml in females. Intracisternal injection (ic) of the stable TRH analog RX 77368 (10 ng) induced significantly higher insulin response in both genders of overnight-fasted GK rats compared with Wistar rats and slightly increased blood glucose in female Wistar rats but significantly decreased it from 193 to 145 mg/100 ml in female GK rats. RX 77368 (50 ng) ic induced markedly greater glucose and relatively weaker insulin responses in male GK rats than Wistar rats. Bilateral vagotomy blocked ic RX 77368-induced insulin secretion, whereas adrenalectomy abolished its hyperglycemic effect. In adrenalectomized male GK but not Wistar rats, ic RX 77368 (50 ng) dramatically increased serum insulin levels by 6.5-fold and decreased blood glucose levels from 154 to 98 mg/100 ml; these changes were prevented by vagotomy. GK rats had higher basal pancreatic insulin II mRNA levels but a lower response to ic RX 77368 (50 ng) compared with Wistar rats. These results indicate that central-vagal activation-induced insulin secretion is susceptible in T2D GK rats. However, the dominant sympathetic-adrenal response to medullary TRH plays a suppressing role on vagal-mediated insulin secretion. This unbalanced vago-sympathetic activation by medullary TRH may contribute to the impaired insulin secretion in T2D.

Aim.To study the associations between blood lipid profile and blood glucose levels in men with coronary heart disease (CHD), stable effort angina (SEA), metabolic syndrome (MS), and Type 2 diabetes mellitus (DM-2).Material and methods.The study included 82 men (mean age 50,5±0,9 years) with CHD, Functional Class I–III SEA, MS, and DM-2. The following lipid profile parameters were assessed: total cholesterol (TCH), triglycerides (TG), low-density lipoprotein cholesterol (LDL–CH), very low-density lipoprotein cholesterol (VLDL–CH), high-density lipoprotein cholesterol (HDL–CH), atherogenic index (AI), and triglyceride index (TGI), together with fasting blood glucose.Results.There were positive (direct) associations between higher levels (>90th percentile) of lipid profile parameters (TCH, TG, LDL–CH, VLDL– CH, HDL–CH, AI, TGI) and blood glucose, as well as between lower levels (≤10th percentile) of lipid profile parameters (TCH, TG, LDL–CH, VLDL– CH, AI, TGI) and blood glucose. At the same time, there were negative (inverse) associations between lower lipid levels (≤10th percentile of TCH, TG, LDL–CH, VLDL–CH, HDL–CH, AI, TGI) and higher glucose levels (>90th percentile), as well as between higher lipid levels (>90th percentile of TCH, TG, LDL–CH, VLDL–CH, HDL–CH, AI, TGI) and lower glucose levels (≤10th percentile).Conclusion.Dyslipidemia and hyperglycemia demonstrate synergetic proatherogenic effects in patients with CHD, SEA, MS, and DM-2, as suggested by significant heterogeneous (direct and inverse) associations between lipid profile parameters and fasting blood glucose. The results obtained provide an opportunity for the assessment of risk levels, prognosis, and need for pharmacological prevention and treatment in patients with combined cardiovascular pathology.

Objective: The objective of the present study was to determine the changes in the glucose level and lipid profile in patients withpolycystic ovarian syndrome (PCOS). Study Design: Descriptive study. Place and Duration of the study: This study was conducted atInstitute of Molecular Biology and Biotechnology, The University of Lahore from June 2009 to June 2010. Patients and Methods: Total 50patients with PCOS were included and 50 age-matched control subjects were also selected for comparison. Their glucose levels and lipidprofile were assessed using commercial kits. The data thus obtained was subjected to statistical analysis. Results: Significant differences(P<0.05) in fasting blood glucose level and individual parameters of lipid profile were observed in women with PCOS. A higher prevalence ofhypertriglyceridemia, hypercholesterolemia, higher LDL, lower HDL and higher fasting blood glucose levels was explored in PCOS womenthan controls. Conclusions: Abnormal glucose level and lipid profile in PCOS women showed that these women are at an increased risk ofdeveloping diabetes and subsequently cardiovascular diseases.

Diabetes mellitus is a metabolic disease that always increasing in prevalence. Excessive glucose intake and oxidative stress that can lead to damage to the pancreatic cell or insulin resistance, are such factors that influence the occurrence of diabetes mellitus. Graptophyllum pictum (L.) Griff leaf contains active metabolites such as flavonoid which able to decrease free radical levels. This study aimed to prove the effectiveness of Graptophyllum pictum (L.) Griff leaves extract on blood glucose levels in alloxan-induced Wistar rats. In this study, twenty-five male Wistar rats were divided into five groups. On day 0, the negative control and each treatment group injected with 125 mg/kg dose of alloxan and would be checked on 4th day. On the 4th day after the rats had diabetes, normal group (K-1) was given only standard feed, Negative control (K-2) was given only alloxan intraperitoneally on day 0, first treatment group (K-3) was given 50 mg/kg dose of Graptophyllum pictum (L.) Griff, second treatment group (K-4) was given 100 mg/kg dose of the leaf extract, and the third treatment group (K-5) was given the leaf 200 mg/kg dose of the leaf extract. On the 10th day, fasting blood glucose was taken from the rats. Post-test only group design was used to be the experimental design. There were significant differences in the treatment groups (K-3, K-4, and K-5) compared to the negative control group (K-2) after treatment. The mean of blood glucose levels decreased with the increased doses of Graptophyllum pictum (L.) Griff leaf extract treatment. The treatment groups (K-3, K-4, and K-5) were not significant compared to the normal group (K-1).

Glycogen Repletion

Patterns of postexercise glycogen repletion in heart, skeletal muscle, and liver in the absence of exogenously supplied substrates during the first 4 h of recovery were assessed. Female Wistar rats were run to exhaustion using continuous (1.0 mph, 15% grade) and intermittent (alternate 1-min intervals at 0.5 and 1.5 mph, 15% grade) exercise protocols. Rats at exhaustion were characterized by marked depletion of glycogen in heart (55%), skeletal muscle (94%), and liver (97%). Blood glucose levels at exhaustion (1.33 mumol/g) were only 37% of preexercise levels. There were no significant differences between continuous and intermittent exercise groups for any of the tissue glycogen or blood glucose values. Cardiac muscle was the only tissue capable of complete restoration of glycogen levels while relying exclusively upon endogenous substrates. Concentrations of endogenous substrates present at the end of exercise were insufficient to support restoration of blood glucose levels to preexercise values nor support glycogen repletion in skeletal muscle and liver during the initial 4-h food-restricted postexercise period. With subsequent feeding, skeletal muscle demonstrated a glycogen supercompensation effect at 24 h (181.1 and 191.8% of preexercise levels for continuous and intermittent exercise, respectively). Lactate concentration in all tissues at the point exhaustion (1.5--2.5 times resting levels) were only moderately elevated and returned to preexercise levels within 15 min. It was concluded that lactate removal after exercise contributed only minimally to the repletion of muscle glycogen.
