<p>The purpose of this study is to evaluate the hypoglycaemic properties and preliminary phytochemical screening of <em>Uveria chamae</em>. The hypoglycaemic properties of <em>Uveria chamae</em> was assessed on normoglycaemic rat that received single dose of the extract at 250 and 500 mg/kg body weight and blood glucose levels estimated at 2, 4, and 6 hours (single dose study). The hypoglycaemic property of the extract was also evaluated in normoglycemic rats by oral glucose tolerance test. Phytochemical screening of the extract for the presence of secondary metabolites was performed with standard methods. The extract showed a significant (p&lt;0.05) reduction in blood glucose levels at 2h and 6h compared to control.  The oral glucose tolerance test  result also showed a significant decrease (p&lt;0.05) in blood glucose levels . The study showed that the extract, <em>Uveria chamae</em> has hypoglycaemic properties which may be accounted for by the presence of the phytochemicals.</p><p> </p>

Background: Corrigiola telephiifolia Pourr, is a perennial species, woody distributed throughout the north of Africa. This plant is used in traditional Mediterranean preparations and has many traditional uses especially treatment of diabetes. Aim/Methods: The current research was carried out to evaluate the antidiabetic effect of Aerial Parts of Aqueous Extract (APAE) of Corrigiola telephiifolia (C. telephiifolia) on both normal and streptozotocin (STZ)-induced diabetic rats treated at a dose of 5 mg/kg for fifteen days. Additionally, the histopathological changes in the liver, morphometric analysis, Oral Glucose Tolerance Test (OGTT) in normal rats and preliminary phytochemical screening for various components were realized. Results: Single oral administration of the APAE of C. telephiifolia (5mg/kg) showed no significant change in glycaemia of normal and STZ-induced diabetic rats. In contrast, repeated oral administration of C. telephiifolia reduced blood glucose levels from 4.11 ± 0.10 mmol/L to 3.16 ± 0.16 mmol/L (p<0.01) 15 days after administration in normal rats. Furthermore, blood glucose levels decreased from 17.84 ± 1.75mmol/L to 1.93 ± 0.33 mmol/L (p<0.0001) in STZ diabetic rats after fifteen days of treatment. According to the oral glucose tolerance test, C. telephiifolia (5 mg/kg) was shown to prevent significantly the increase in blood glucose levels in normal treated rats 30 min after glucose administration when compared to the control group. Also, the liver architecture of diabetic rats treated by C. telephiifolia was improved when compared with the liver architecture of untreated diabetic rats. Concerning the preliminary phytochemical screening of C. telephiifolia, several compounds have been found such as polyphenols, flavonoids, saponins, mucilage and terpenoids. Conclusion: The results show that the aqueous extract of C. telephiifolia possesses significant antihyperglycemic activity.

Diabetes is a chronic metabolic disorder characterized by a high blood glucose concentration, i.e., hyperglycemia or caused by insulin deficiency, often combined with insulin resistance. In the Present study, the antidiabetic and antioxidant activity of the methanolic extract of Tagetes patula flower heads was screened out in rodent models. The pharmacological evaluation was carried out using 200 and 400 mg/kg, b.w. The in-vivo antidiabetic activity was performed in streptozotocin, dexamethasone-induced diabetic models and oral glucose tolerance test. Metformin hydrochloride was used as a standard. The parameters like blood glucose levels, insulin levels, homeostasis assessment of insulin resistance, insulin sensitivity, and fasting glucose-insulin ratio were estimated in these models. The in-vitro antioxidant activity of methanolic extract of Tagetes patula was performed by using hydroxyl radical scavenging assay and Ascorbic acid was used as a standard. The preliminary phytochemical screening of Tagetes patula revealed the presence of phytoconstituents like alkaloids, flavonoids, saponins, steroids, phenols, carbohydrates, triterpenoids, and tannins. The extract showed a significant decrease in the elevated blood glucose levels in streptozotocin, dexamethasone-induced diabetic models, and also in the oral glucose tolerance test. The extract prevented insulin resistance and significantly increased insulin sensitivity in the dexamethasone-induced model. The various phytochemical constituents like alkaloids, flavonoids, saponins, steroids, and phenols might be responsible for lowering the blood glucose levels in the animal models mentioned above. The extract showed significant scavenging activity against hydroxyl free radicals. From the above outcomes, it is flawless that the methanolic extract of Tagetes patula has antidiabetic and antioxidant activities.

Objective The objective of the present study was to compare 24-hour glycemic levels between obese pregnant women with normal glucose tolerance and non-obese pregnant women. Methods In the present observational, longitudinal study, continuous glucose monitoring was performed in obese pregnant women with normal oral glucose tolerance test with 75 g of glucose between the 24th and the 28th gestational weeks. The control group (CG) consisted of pregnant women with normal weight who were selected by matching the maternal age and parity with the same characteristics of the obese group (OG). Glucose measurements were obtained during 72 hours. Results Both the groups were balanced in terms of baseline characteristics (age: 33.5 [28.7–36.0] vs. 32.0 [26.0–34.5] years, p = 0.5 and length of pregnancy: 25.0 [24.0–25.0] vs. 25.5 [24.0–28.0] weeks, p = 0.6 in the CG and in the OG, respectively). Pre-breakfast glycemic levels were 77.77 ± 10.55 mg/dL in the CG and 82.02 ± 11.06 mg/dL in the OG (p<0.01). Glycemic levels at 2 hours after breakfast were 87.31 ± 13.10 mg/dL in the CG and 93.48 ± 18.74 mg/dL in the OG (p<0.001). Daytime blood glucose levels were 87.6 ± 15.4 vs. 93.1 ± 18.3 mg/dL (p<0.001) and nighttime blood glucose levels were 79.3 ± 15.8 vs. 84.7 ± 16.3 mg/dL (p<0.001) in the CG and in the OG, respectively. The 24-hour, daytime, and nighttime values of the area under the curve were higher in the OG when compared with the CG (85.1 ± 0.16 vs. 87.9 ± 0.12, 65.6 ± 0.14 vs. 67.5 ± 0.10, 19.5 ± 0.07 vs. 20.4 ± 0.05, respectively; p<0.001). Conclusion The results of the present study showed that obesity in pregnancy was associated with higher glycemic levels even in the presence of normal findings on glucose tolerance test.

ABSTRACT. The procedure for diagnosing diabetes mellitus when accompanied by classical symptoms is based on random blood glucose levels of 7 mmol/l or more. Problem of diagnosing diabetes in the asymptomatic subject remains difficult. A procedure based on fasting blood glucose levels below 5.5 mmol/l in normals and reproducible values at or above 7 mmol/l in diabetics is proposed. In cases with fasting blood glucose values between 5.5 and 7 mmol/l standardized oral glucose tolerance test is recommended. The diagnostic criteria for normality, impaired glucose tolerance and for diabetes are evaluated against the results of a 10–14 years prospective study.

Introduction: Pre-diabetes is a condition that persists for a considerable duration before progressing into type 2 diabetes mellitus (T2DM). Development of resistance to insulin is the underlying cause of pre-diabetes, preventive measures such as diagnosis, treatment and exercise will preclude its development into T2DM. The present study aims at studying the effect of pre-treatment and post-treatment with isolated fraction of Costus igneus on pre-diabetes and diabetes in neonatal streptozotocin (STZ) induced T2DM.Methods: Neonatal rats were treated with STZ and differentiated for pre-treatment and post-treatment. Rats of pre-treated group were treated with isolated fraction of Costus igneus (CIF) from 4th week after STZ administration and after 12th week in non-treated rats of post-treatment group. The antihyperglycemic was studied on 7th and 12th week after STZ treatment using oral glucose tolerance test and the hypoglycemic effect was studied on day 1, 7, 14 and 21 of treatment after 12th week of STZ treatment in both pre and post treated groups.Results: Oral glucose tolerance test on 7th and 12th week had shown a protective effect against increase in blood glucose levels in pre-treated groups whereas, no such significant decrease was observed in non-treated groups. In the effect on hypoglycemia, a reduction in blood glucose levels was observed on treatment with CIF in both pre and post treated rats on 14th and 21st day.Conclusions: Treatment with CIF in pre-diabetic stage could reduce the chances of progression into T2DM and is also beneficial in diabetic rats, which could be due to increase in the peripheral utilization of glucose and the insulin mimetic effect of Costus igneus.
