This study deals with the effects of freeze dried rhizome powder of Curcuma longa (C. longa) dissolved in milk on normal as well as diabetic models. Diabetes of type II and type I was within 3 days of a single administration of doses of 45 and 65 mg kg−1 of streptozotocin respectively. Various parameters such as blood glucose levels, triglycerides, total cholesterol, high density lipoprotein, very low density lipoprotein, low density lipoprotein, serum glutamic oxaloacetic transaminase, serum glutamic pyruvate transaminase, alkaline phosphatase, creatinine, hemoglobin, urine protein and urine sugar in addition to body weight were taken in to consideration and were analyzed after administration of variable doses of rhizome powder. The dose of 200 mg kg−1 was identified as the most effective dose as it increased HDL, Hb and bw (P<0.05) with significant decrease in the levels of blood glucose, lipid profile and hepatoprotective enzymes (P<0.001).  相似文献

The cause of more insulin resistance in female than males are still unknown. To know the cause from early life, normal values of relevant parameters are required. So, aim of this study was to determine the reference levels of glucose and insulin in cord blood of term newborns and to examine their effects on gender, placental and birth weight of term newborns. In cross sectional study 60 consecutive term newborns were included from constituent hospitals. Placental and birth weights were measured and cord blood was collected for estimation of serum insulin and plasma glucose. Plasma glucose estimation was done by auto analyzer (GOD–POD method) and serum insulin analysis was done using Insulin ELISA Kit. After analysis, mean ± 2SD used for estimating cord blood insulin and glucose levels, which were 10.1 ± 7.8 μIU/mL and 67.8 ± 33.8 mg/dL respectively. Correlation of insulin with both birth weight and placental weight were r = 0.359 and 0.41 respectively; p < 0.001. Interestingly we found higher insulin levels in females as compared to male newborns in spite of having lower birth weight in them. In conclusion this study reported the levels of insulin and glucose in cord blood of term newborns. Incidentally, this is the first study as per our knowledge to report significant correlation between cord blood insulin, glucose with birth weight, placental weight and gender in south India. Female newborns had higher insulin levels than males, despite lesser birth weight can be attributed to intrinsic insulin resistance in them.  相似文献

The present study investigated the effect of an antianxiety drug, buspirone on blood glucose and plasma insulin level concerning the role of 5-HT1A receptors in blood glucose regulation in healthy humans. Twelve healthy male volunteers were administered single oral doses of buspirone (10 mg) or placebo, in a randomized, crossover way, followed by oral glucose load (75 gm in 200 ml) at reported Tmax i.e. the time of peak plasma concentration of the respective administered drug. The blood samples were collected as predose, postdose and post oral glucose load at 0.5, 1.0, 1.5, 2.0, 2.5 and 3.0 hr to investigate the effect of buspirone or placebo at basal blood glucose and plasma insulin level and after oral glucose load induced (postprandial) blood glucose and plasma insulin level. Blood glucose and plasma insulin concentrations were estimated by glucose hexokinase method and enzyme linked immunosorbent assay (ELISA) method respectively. The concentration of blood glucose was significantly (p<0.05) decreased after oral glucose load following administration of buspirone in comparison with placebo however no significant change was observed in the fasting blood glucose and plasma insulin (fasting and oral glucose load induced) level. In conclusions, the present study findings show that buspirone produced a significant alteration in blood glucose level in healthy humans. In addition, study results also indicate that the involvement of serotonergic (5-HT, receptors) mechanism of blood glucose regulation in humans is different from animals.  相似文献

To determine the normal range of Hemoglobin and cutoff values in healthy adults of Southern India, blood samples were analyzed for parameters of RBC and iron metabolism in 177 male and 203 female medical students. The data were compared with the American white population (NHANES III) and the WHO criteria for detection of anemia. The mean values for hemoglobin and hematocrit in male students differed minimally from American white males. However, values for parameters of iron metabolism were lower except total iron binding capacity (TIBC) which was higher. In female students, hemoglobin, hematocrit and parameters of iron metabolism were lower than American white females, except TIBC which was higher. Lower 5th percentile cutoff point (Mean − 1.645 SD) in males and females were 13.5 and 10 g/dl respectively. In conclusion, South Indian adult males have Hb values similar to American male adults, but South Indian females have considerably lower Hb levels than American females, raising the questions about appropriateness of WHO or US criteria for detection of anemia in Indian females.  相似文献

Whole blood and plasma selenium levels were measured in 40 healthy Indian residents living in and around Delhi (20 males and 20 females). The mean whole blood and plasma selenium levels were 169.0±40 and 139.0±36.7 ng/ml in males and 161.2±46.2 and 128±40.6 ng/ml (mean±SD) in females, respectively. These blood levels did not differ significantly between males and females and are consistent with adequate selenium status. From regression plots based on the present results and literature data, it is expected that the probable mean selenium intake could be about 122 and 112 μg/day in males and females respectively.  相似文献

Although HbA1C is widely accepted as a useful index of mean blood glucose in type 2 diabetic patients its usefulness as screening test for diabetes has been controversial. The present study was undertaken to determine whether the level of HbA1C predicted diabetes in a prediabetic group of subjects. Plasma lipids, oral glucose tolerance, HbA1C was determined in 90 normal control subjects, 57 offspring of one type 2 diabetes mellitus parent and 11 diagnosed type 2 diabetes mellitus individuals. The mean age of participants was 44.5 yrs (not significantly different amongst the three groups) and the mean body mass index was 26.8 (not significantly different amongst the three groups). Two hours after a 75 g glucose challenge, the offspring had a significantly higher plasma glucose level (mean = 7.1 mmol/L, p value = 0.002) than the normals. Similarly the HbA1C values were higher in the offspring than in the normals (mean = 5.78%, p value = 0.016). Besides the significantly higher values for oral glucose tolerance test and HbA1C, the diabetics also were significantly higher for triglycerides (mean = 2.25mmol/L), total cholesterol (mean = 6.24mmol/L) and systolic blood pressure (mean = 138.45mm Hg) than the offspring (P value = 0.031, 0.006, 0.010) and the normals (P value = 0.026, 0.018, 0.002) respectively. The mean values of diastolic blood pressure, LDL cholesterol and HDL cholesterol were not significantly different amongst the three groups.  相似文献

Musa cavendish, peels has local and traditional use to promote wound healing, hyperglycemia, ulceration etc. The present work investigated the lipid lowering; nephroprotective and glucose lowering properties of ethanolic extract of peels of Musa cavendish (EMC) in alloxan-induced diabetic rats. The EMC 250, 500 and 1000 mg/kg/day and the vehicle were administered orally to alloxan-induced diabetic rats (n = 6) for 3 weeks. Changes in plasma glucose, lipid profile along with kidney function before and after treatment with EMC were recorded. The ethanolic extract of peels of Musa cavendish reduced blood glucose, serum triglyceride, cholesterol, LDL cholesterol and creatinine levels and improvement in body weight, liver glycogen, serum HDL cholesterol, serum albumin and total protein level when compared with untreated rats. Musa cavendish has lipid lowering, nephroprotective and antidiabetic property by regulating glucose uptake in the liver and muscles by restoring the intracellular energy balance.  相似文献

Some biochemical parameters in 12 young Muslim students who underwent fasting during the entire one month period of Ramadan were investigated. There was a significant reduction in their body weight (72.5±4.0 to 69.4±3.0 kg) and blood glucose levels (99.6±3.5 to 82.9±7.3 mg/dl). Though the morning plasma cortisol fell (215.2±22.1 to 105±11.2 μg/l) and the evening plasma cortisol rose (58.4±5.1 to 64.4±4.8 μg/l) significantly there was no reversal of the circadian rhythm of cortisol secretion. A decline in the diastolic blood pressure (80 to 75±6 of Hg) of these individuals though not significant was also noted. However, cholesterol (160.9±12.8 to 178.2±40.6 mg/dl) and HDL-Cholesterol (42.6±2.2 to 48.1±2.4 mg/dl) showed a tendency for increase. All the changed values were within the normal range.  相似文献

Present investigation shows that hydroethanolic extract of Moringa oleifera (MOHE) and its isolated saponin (SM) attenuates DMBA induced renal carcinogenesis in mice. Isolation of SM was achieved by TLC and HPLC and characterization was done using IR and 1H NMR. Animals were pre-treated with MOHE (200 and 400 mg/kg body weight; p.o), BHA as a standard (0.5 and 1 %) and SM (50 mg/kg body weight) for 21 days prior to the administration of single dose of DMBA (15 mg/kg body weight). Administration of DMBA significantly (p < 0.001) enhanced level of xenobiotic enzymes. It enhanced renal malondialdehyde, with reduction in renal glutathione content, antioxidant enzymes and glutathione-S-transferase. The status of renal aspartate transaminase, alanine transaminase, alkaline phosphatase and total protein content were also found to be decreased along with increase in total cholesterol in DMBA administered mice. Pretreatment with MOHE and SM significantly reversed the DMBA induced alterations in the tissue and effectively suppressed renal oxidative stress and toxicity.  相似文献
