We aimed to evaluate the effect of anti-diabetic activity of Terminalia arjuna, and Syzygium cumini extracts in Streptozotocin (STZ) induced diabetes in Wistar rats. STZ (55mg/kg) followed by nicotinamide (100mg/kg) was given to rats by intraperitoneal route to induce diabetes. Oral administration of alcoholic and hydro-alcoholic extracts of T. arjuna (TAAE) (250mg/kg and 500mg/kg), S. cumini (SCAE) (200mg/kg and 400mg/kg) and their composite extract were given to rats along with standard anti-diabetic drug Glibenclamide (5mg/kg). We evaluated body weight, glucose level, lipid profile and biochemical parameters in STZ induced diabetic rats. Also, histopathological studied were done in liver, kidney and pancreatic tissues of rats. Our finding revealed that TAAE and TAHE at 250mg/kg b.w. and 500mg/kg b.w., SCAE and SCHE at 400mg/kg b.w. and combination of TAAE (250mg/kg b.w.)+SCAE (400mg/kg b.w.) had a positive effect in lowering the blood glucose level and body weight on 28th day as compared to the initial observation on 0th day and also restored all the biochemical parameters such as LDL, VLDL, triglycerides and total Cholesterol and HDL towards the normal levels as well as histopathological improvement in Kidney, Liver and Pancreas. Data analysis showed that composite extract of TAAE (250mg/kg) and SCAE (400mg/kg ) improved diabetic consequences more effectively than composite extract of TAHE (500mg/kg) and SCHE (400mg/kg). TAAE and SCHE, in combination, demonstrate as a potential therapeutic agent against diabetes.

The present study explored the assessment of the antidiabetic potential of Tinospora cordifolia & Juglans regia composite extract in STZ induced diabetes in wistar rats. As streptozotocin -associated infiltrations of increase glucose level has been reported to be responsible for diabetes. We evaluated the glucose lowering potential of Tinospora cordifolia & Juglans regia on the basis of its anti-diabetic property. Rats were administered streptozotocin (55 mg/kg i.p., once) with nicotinamide (120mg/kg) to induce experimental toxicity. The development of diabetes was assessed biochemically as well as histologically 72 hours after induction of diabetes. Body weight and blood glucose levels were determined in (0, 7th, 14th, 21st, 28th) days. Serum lipid profile and enzyme estimated, (kidney, liver, pancreas) tissue was measured at the end of the experimental period. Treatment with composite extracts TCAE high dose (350 gm/kg b.w.) & JRAE high dose (800 mg/kg b.w.) and TCHE high dose (350 gm/kg b.w.) & JRHE high dose (800 mg/kg b.w.) were noted to be more effective against the streptozotocin- induced toxicity as compared to Glibenclamide (5 mg/kg b.w.). it may be concluded that streptozotocin-induced glucose may be accountable for the induction of diabetes toxicity in rats. Interestingly, improvement in body weight, glucose level, lipid profiles, biochemical parameters and histopathological changes in kidney, liver and pancreas was observed following herbal treatment in STZ induced diabetic rats. Furthermore, composite extract of TCAE (350mg/kg b.w.) & JRAE (800mg/kg b.w.) was found to be efficacious than the composite extract of TCHE (350mg/kg b.w.) & JRHE (800mg/kg b.w.).

Ruellia tuberosa L. is a therapeutic plant that is generally consumed in Indonesian traditional medicine to prevent or cure various illnesses, i.e., diabetes. The current study was conducted to investigate the effects of hydroethanolic root extracts of Ruellia tuberosa L. on the kidney of streptozotocin-induced diabetic Wistar rats. In this study, male Wistar rats were divided into 5 groups: healthy rats (group 1), diabetic rats (group 2), and treated rats which received extract at dosages of 250 (group 3), 375 (group 4), and 500 (group 5) mg/kg body weight for 21 days. Diabetes mellitus was experimentally induced by the administration of five doses of streptozotocin 20 mg/kg body weight within five consecutive days. Significant increases in the value of TNF alpha expression and malondialdehyde (MDA) levels were observed in streptozotocin-induced diabetes rats. Furthermore, severe histological alterations of kidney tissues occurred in the diabetic rats group. After treatment was applied, the value of TNF alpha expression and MDA levels on the kidney decreased considerably p < 0.05 in groups 3, 4, and 5. The optimum dosage was obtained at a dose of 250 mg/kg body weight (group 3), which had 42.24% and 52.70% decrease in TNF alpha expression and MDA levels, respectively. The histopathological profiles of the kidney also showed significant improvements in treated groups. The most prominent recoveries were also shown in group 3. The treatments induced repairment in the glomerular and renal tubular damages in the kidney tissues. To conclude, these results emphasize potentially health valuable properties of hydroethanolic root extracts of R. tuberosa L. in rats with streptozotocin-induced diabetes.

Study was conducted to evaluate the hepatoprotective effects of Seabuckthorn leaf extract (SLE) supplementation on serum enzymatic levels in streptozotocin (STZ) induced diabetes mellitus in Wistar rats. Thirty-two adult male Wistar rats were divided into four groups namely CON (negative control), SCO (Seabuckthorn control), DCO (Diabetic control), and DSL (Diabetic seabuckthorn treatment group). Diabetes mellitus was induced by single intra peritoneal injection of STZ @ 50 mg/kg body weight in DCO and DSL group of rats. SLE was administered orally @ 100mg/kg body weight for 40 days to SCO and DSL groups. CON served as the negative control. Blood samples were collected from experimental animals on zero, 20th, and 40th days of trial to study liver specific serum enzyme profile viz aspartate amino transaminase (AST), alanine amino transaminase (ALT), alkaline phosphatase (ALP) and acid phosphatase (ACP). Significantly (P less than 0.01) higher levels of all the enzymes studied were observed in experimentally induced diabetic rats in comparison to normal rats. However, in SLE treated diabetic rats (DSL group), significant (P less than 0.01) improvement was observed in all the above enzymes. It may be concluded that SLE exerts hepatoprotective effect in STZ induce Diabetes mellitus in Wistar rats.

PURPOSE: To compare body weight and length, heart weight and length, heart-to-body weight ratio, glycemia, and morphometric cellular data of offspring of diabetic rats (ODR) and of normal rats (control). METHODS: Diabetes was induced in 3 pregnant Wistar rats, bearing 30 rats, on the 11th day after conception by intraperitoneal injection of 50 mg/kg of streptozotocin. Six normal pregnant Wistar rats, bearing 50 rats, made up the control group. Morphometric data were obtained using a scale for the weight, length, heart and body measurements. Morphometric cellular data were obtained by a computer assisted method applied to the measurements of myocytes. Statistical analysis utilized Student's t-test, ANOVA and Levene test. RESULTS: Control offspring had greater mean body weight and length than offspring of diabetic rats (p < 0.001). Heart weight and length and heart-to-body ratios of newborn rats differed between groups at birth (p < 0.001), but showed no difference at 21 days. Mean nuclei area and perimetric value of the myocytes decrees throughout the first 21 days of life (p < 0.01) in the diabetic group. CONCLUSIONS: Heart hypertrophy on the offspring of diabetic rats at birth was demonstrated by the significant difference between the groups. After the eleventh day, no difference was found, which confirmed regression of cardiomegaly. The significant difference between the first and the 21th day of life, for nuclei area feature, demonstrate regression of cardiac hypertrophy in the offspring of diabetic rats.

Aims: To investigate the effect of food blends (plantain, soybean and ginger) on the blood glucose, lipid profile and haematological indices on streptozotocin induced diabetic rats. Methodology: A total of 35 rats of mean body weight 219.07 g separated into7 groups (5 per group) where induced by a single intraperitoneal (I.P) injection of streptozotocin (0.1 g dissolved in 5 ml of freshly prepared sodium citrate buffer 0.1 M, pH 4.5) at a dose of 40 mg/kg body weight after fasting for 12 hours and fed with flours/blends. The flours were produced from plant materials for different treatments/blends (blend A=100% unripe plantain, B=80% unripe plantain, 14% soybean, 6% ginger, C=70% unripe plantain, 26% soybean, 4% ginger, D= 60% unripe plantain, 38% soybean, 2% ginger, E= 50% unripe plantain, 50% soybean) and the phytochemicals and minerals content were determined. Blood glucose was determined at 5 days interval for 25 days. Diabetes was confirmed in rats with blood glucose concentrations >200 mg/dl. After 25 days rats were anaesthetized with chloroform vapour and blood samples collected by cardiac puncture for haematology and lipid profile determination. Results: The results showed that unripe plantain, soya beans and ginger in adequate proportion(C=70% unripe plantain, 26% soybean, 4% ginger or D= 60% unripe plantain, 38% soybean, 2% ginger) could help to reduce blood glucose, improve haematological parameters and lipid profile. Significant reduction was observed in the blood glucose level of rats fed blends C and D from 286 to 85 mg/dl and 307 to 90 mg/dl respectively at the end of experiment. These results also demonstrated that the inclusion of ginger at 6% causes rise in blood glucose level. Total cholesterol (TC) increased in all the blends. However, the lowest concentration of TC was observed in blends C and D. The highest packed cell volume (60%) and Haemoglobin (20 g/dl) level observed in rats fed blend C was significantly higher than the normal control fed conventional feeds. The increase in packed cell volume (PCV) (50%) and Hb (17 g/dl) in diabetic rats demonstrated that the formulated blend C was able to raise PCV and Hb above 50% and 17 g/dl (Normal control NC) respectively. Significant increase (P<0.05) in low density lipoprotein cholesterol (LDLc) was also observed in all the blends with blend C having the least (4.0 mg/dl) close to NC (2.0 mg/dl). Conclusion: From the results it is evident that blend C will manage and improve the health status of diabetic patients.

Background. Herbal medication is a worldwide and ancient practice, mostly in developing countries, where a large part of the population is involved in this practice. Hence, studies must be conducted to evaluate their safety and efficiency to avoid or prevent toxicological risks due to their usage. In Togo, Carissa spinarum is a medicinal plant belonging to Apocynaceae family, used as an aphrodisiac or to heal some ailments including malaria, sickle cell anemia, hypertension, pain, and asthma. Notwithstanding its several ethnomedicinal benefits, just a few toxicological data associated with its chronic use are available. Objective. Therefore, this study aims to assess the toxicity of an ethanolic root extract of Carissa spinarum in Wistar rats. Methods. The 90-day oral toxicity process following OECD TG 408 guidelines is used. Male Wistar rats received Carissa spinarum root hydroethanolic extract at 500 and 1000 mg/kg for 90 days by oral gavage. Body weight changes, hematological and blood biochemical parameters, organ weight changes, malondialdehyde as a lipoperoxidation marker expressed according to tissue proteins, and histopathology of vital organs were assessed. Results. No signs of toxicity or mortality were observed during the 90 days experiment. Hematological parameters have not shown any treatment-related abnormalities. According to biochemical parameters, an increase in the chloride ion level was observed at 1000 mg/kg p < 0.01 . There was no significant difference between the treated groups and the control group concerning the malondialdehyde concentration, body weight, and organ relative weight. No changes in necropsy and histopathology of vital organs associated with extract treatment were observed. Conclusion. The results indicated that an ethanolic root extract of Carissa spinarum does not cause adverse effects, which can lead to Wistar rats’ death after 90-day oral administration at 500 and 1000 mg.

Diabetes is a chronic disease which characterized by hyperglycemia (elevated or abnormally high blood sugar levels) and other metabolic disturbances, including metabolism of lipids and haemostasis. Caesalpinia pulcherrima has previously showed strong anti-diabetic and hepatoprotective potential. The present research work was to investigate the anti-diabetic activity and hepatoprotective activity Caesalpinia pulcherrima in streptozotocin-induced (STZ) diabetic rats. The dose-dependent effects of 45days oral treatment with methanol extract of plant (200 and 300mg/kg) of CPAE on body weight, blood glucose level, total protein, albumin, liver marker enzymes and carbohydrate metabolizing enzymes were evaluated in STZ-induced diabetic rats. Oral administration methanolic extract of Caesalpinia pulcherrima of showed significant restoration of the body weight and decrease in the blood glucose level, liver marker enzymes (ALT, AST ALP) and carbohydrate metabolizing enzymes were observed in diabetic rats. These results suggest that fruit extract of Caesalpinia pulcherrima has valuable anti-diabetic activity in STZ-induced diabetic rats which is comparable to the standard drug metformin and hence might be of use in the management of diabetes.

PURPOSE: To determine podocyte number and GBM thickness in diabetic rats either under glycemic control or without glycemic control at 6 and 12 months after diabetes induction. METHODS: 100 wistar rats weighing 200-300g were divided into 6 groups: Normal group (N6 and N12- 25 rats); Diabetic group (D6 and D12- 25 rats), diabetic treated group ( DT 6 and DT 12- 25 rats) on insulin 1,8- 3,0 IU/Kg associated with acarbose (50mg to 100g of food) daily mixed in chow. Alloxan was injected intravenously in a dose of 42 mg/Kg of weight. Body weight, waterintake, 24-h diuresis, glycemia and glucosuria were determined before induction, 7 and 14 days after induction and monthly thereafter. Treatment started at day 14. Three groups were sacrificed at 6 months (N6,D6, DT6) and 3 groups at 12 months (N12, D12, DT12) with the renal tissue being prepared for electron microscopy. RESULTS: Glycemia in DT6¨and in DT12 was significantly different from that in D6 and D12 rats and similar to that in N6 and N12 animals. The number of podocytes in DT6 was not different from that in N6 and D6 (median = 11); the number of podocytes in DT12 (median = 11) differed from that in D12 (median = 8), but not from that in N12 (median = 11). GBM thickness in D6 (0.18 micrometers) was lower than in D12 (0.29 micrometers); while in DT6 (0.16 micrometers) it was lower than in D6 (0.18 micrometers). In DT12 (0.26 micrometers), it was lower than in D12 (0.29 micrometers). CONCLUSION: The control of hyperglycemia prevented GBM thickening in early and late (12 mo) alloxan diabetic nephropathy and podocyte number reduction.
