AbstractAimTo study the protective response of herbal formulation (tablets) of Pueraria tuberosa water extract (PTAB) on alloxan induced rat diabetic model.MethodologyAlloxan (120 mg/kg bw) was injected intraperitonially. Rats were divided into three groups: group 1 as normal, group 2 as diabetic control and group 3 were given PTAB upto 14 days. Blood glucose and liver function tests were done using their respective kits. Hematoxylene and eosin staining was done to evaluate the morphological changes in liver tissues. Through immunohistochemistry, we have checked the protein expression of VEGF, MMP9 and ki67.ResultPTAB significantly decreases blood glucose level in a time dependent manner up to 14 days. As compared to diabetic control, PTAB decreases SGOT, SGPT and alkaline phosphates after 14 days of treatment. In diabetic control, the morphology of liver tissues were found damaged due to deformed hepatocytes and dilated lobules. Most of the hepatocytes after PTAB treatment were comparatively found similar to normal rats tissues, along with dilated blood vessels and normalized liver lobules. In addition to these results, PTAB suppresses the expressions of VEGF and MMP 9.ConclusionPTAB was found to act as an effective hypoglycemic agent. In addition to this, PTAB also found to inhibit inflammation and apoptosis of liver. Thus, can be taken as a potential drug in liver diseases.

During follicular development in the mammalian ovary, several functional changes occur in the granulosa cells in response to steroid hormones and gonadotropins (1,2). In particular, marked changes in the content of membrane-associated receptors for the gonadotropins have been observed (1).We report here scanning electron microscope observations of morphological changes that occur on the granulosa cell surface in response to the administration of estradiol, human follicle stimulating hormone (hFSH), and human chorionic gonadotropin (hCG).Immature female rats that were hypophysectcmized on day 24 of age were treated in the following manner. Group 1: control groups were injected once a day with 0.1 ml phosphate buffered saline (PBS) for 3 days; group 2: estradiol (1.5 mg/0.2 ml propylene glycol) once a day for 3 days; group 3: estradiol for 3 days followed by 2 days of hFSH (1 μg/0.1 ml) twice daily, group 4: same as in group 3; group 5: same as in group 3 with a final injection of hCG (5 IU/0.1 ml) on the fifth day.

IntroductionThe study aimed to evaluate Choroidal Vascularity Index (CVI) of Haller’s and Sattler’s layers and their relationships with choroidal and retinal thickness, volumes measured on enhanced depth imaging–optical coherence tomography (OCT) scans in the eyes of patients without diabetes, patients with diabetes with no diabetic retinopathy (DR) and patients with diabetes and DR.Research design and methodsRetrospective analysis of 165 eyes from 84 Singapore Indian Eye Study-2 study participants (group 1: no diabetes, group 2: diabetes with no DR and group 3: with DR). Groups 1 and 2 were matched by age and gender from group 3.ResultsIn the eyes of patients with diabetes without DR, the macular CVI of Haller’s but not Sattler’s layer was significantly reduced compared with eyes of patients without diabetes. Eyes with >5 years of diabetes have significantly decreased CVI of Sattler’s layers (mean difference=0.06 ± 0.10, p=0.04) and also decreased subfoveal choroidal volume (mean difference=0.89 ± 0.16 mm3, p=0.02), compared with those with ≤5 years of diabetes.ConclusionDiabetic eyes without DR had significantly lower CVI of macular Haller’s layer than those of healthy controls. With a longer duration of diabetes, CVI of subfoveal Sattler’s layer and choroidal volume continue to decrease, irrespective of diabetic control, suggesting that early diabetic choroidopathy mainly affects larger choroidal veins initially before medium-sized arterioles. The CVI of macular Haller’s layer could potentially be used as a marker on spectral domain OCT imaging in newly diagnosed patients with diabetes for the onset of DR and as a possible prognostication tool in diabetic eyes. Future prospective longitudinal studies in diabetic eyes would be useful in establishing the relationship between CVIs of Haller’s and Sattler’s layer with visual acuity as a marker of photoreceptor health and visual prognosis.

Objective: This study aimed to evaluate the antidiabetic and antidepressant effects of banana peel flakes in streptozotocin-induced diabetic rats. Methods: Twenty-five male Wistar rats were classified into five groups with different treatments. Groups I to IV were diabetic rats model groups that consumed only standard diet, standard diet containing 5%, 10%, and 20% of banana peel flakes, respectively. While group V was a healthy control group fed a standard diet. Immunohistochemistry staining was measured to examine serotonin expression in the colon and pancreas. Results: The diabetic rats treated with 20% banana peel flakes had a lower blood glucose concentration (p<0.05) compared with diabetic control and showed a shorter duration of immobility time (p<0.05) than the healthy control. Additionally, compared with diabetic control, the diabetic rats treated with 5% banana peel flakes showed higher serotonin expression (p<0.05) in the colon. In contrast, serotonin expression in the pancreas did not show any significant difference (p>0.05). Conclusion: The present study disclosed that the banana peel flakes provided an antidepressant effect in the diabetic rats model, which might occur through the mechanism of controlling blood glucose concentration.

This study was designed to confirm the effect of different concentrations of water extract for stevia leaves on lowering blood sugar, cholesterol and other blood traits in diabetes-induced mice. Forty mice with weights ranging 30-35 mg per diabetic were injected intravenously into the gastric tube except for control group (non-diabetic control) and were left for one week to confirm their diabetes. The animals were divided randomly into 5 groups with 8 mice per group; animals were given in group 1 (non-diabetic control) and group 2 (diabetic control) fed standard diet with water supply, while groups 3, 4 and 5 were fed standard diet and different concentrations 300, 400 and 500 mg / dl / day respectively of aqueous extract of stevia leaf powder for a period of three weeks. A significant reduction was found in blood sugar, cholesterol, total fat and equal levels of other blood traits in groups 3 and 4 compared to group 2. The results also showed that giving the aqueous extract of Stevia at a concentration of 300 and 400 mg/kg weight, the blood sugar level is statistically and directly reduced in all treated diabetes-induced groups of mice. It also led to a statistical reduction of cholesterol and triglyceride. There is also a statistically significant increase in other blood characters in diabetic mice was also found that leaves of the stevia plant contained 7,86, 5,28 and 2,58% for both steviol glycoside, stevioside and rebaudoside respectively that measured by HPLC technique. These results have shown that consumption the leaves extract of stevia plant have an important role in reduction blood sugar, cholesterol and total fat, as well as other blood traits in mice induced for diabetes.

Objective. To study the adaptive capacity of a single remaining kidney in the early postoperative period of nephrectomy in an experiment. Materials and methods. The experiment involved 35 laboratory white rats, which were divided into three experimental groups. Group 1 (n = 5) intact animals, group 2 (n = 15) animals underwent nephrectomy on the left; group 3 (n = 15) animals underwent nephrectomy and additionally were created 90 minute hypoxic hypoxia. Histological material was collected on the 5th, 21st and 60th days after surgery. Results. Characteristic morphological changes in the only remaining kidney were an increase in the size of the glomeruli and a decrease in their number. Nephron fibrosis was detected, accompanied by increased production of antigens by the tubular epithelium, which is likely a response to a cascade increase in oxidative stress and increased release of cytokines that stimulate the production of intrarenal collagen. Conclusion. Nephrectomy and hypoxia are provocateurs for the development of systemic distress syndrome, the result of which is the formation of a vicious pathogenetic circle, which reduces the functionality of the renal tissue. This can be considered as one of the early preclinical mechanisms for the initiation of single kidney disease in the future.

Purpose: To investigate the effect of Polygonatum sibiricum extract (PSE) on streptozotocin-induced diabetic rats. Methods: PSE was obtained by steeping the dried Polygonatum sibiricum in water at 60 oC three times, each for 1 h, before first drying in an oven at 100C and then freeze-drying the final extract, thus obtained. Diabetic model rats were prepared by a single intraperitoneal injection of a freshly prepared solution of streptozotocin (50 mg/kg). The rats were randomly divided into 6 groups of ten rats each: negative control, normal control, reference (glibenclamide1 mg/kg) as well as PSE groups, (35, 70 and 140 mg/kg). Blood glucose and plasma insulin levels were measured to determine antihyperglycemic effect. Oxidative stress was evaluated in liver and kidney by their antioxidant markers, viz, lipid peroxidation (LPO), superoxide dismutase (SOD), reduced glutathione (GSH), glutathione peroxidase (GPx) and catalase (CAT). Blood serum levels of creatinine and urea were determined in both diabetic control and treated rats. Results: Compared with diabetic rats, oral administration of PSE at a concentration of 120 mg/kg daily for 30 days showed a significant decrease in fasting blood glucose (118.34 ± 3.29 mg/dL) (p < 0.05) and increased insulin level (12.86± 0.62 uU/mL, p < 0.05). Furthermore, it significantly reduced biochemical parameters (serum creatinine, 0.83 ±0.21 mg/dL, p < 0.05) and serum urea (43.26±1.42 mg/dL, p < 0.05). Conclusion: The results suggest that PSE may effectively normalize impaired antioxidant status in streptozotocin-induced diabetes in a dose-dependent manner. Thus, PSE has a protective effect against lipid peroxidation by scavenging free radicals, restoration of insulin function, and reduction of the incidence of complications.

Background: Monosodium glutamate (MSG) is a flavour enhancer which induces behavioural changes in animals. However the influence of sex on the behavioural response to MSG has not been investigated. Objective: The sex-differential effects of MSG on open-field behaviours, anxiety-related behaviour, behavioural despair, place-preference, and plasma/brain glutamate levels in adult mice were assessed. Methods: Mice were assigned to three groups (1-3), based on the models used to assess behaviours. Animals in group 1 were for the elevated-plus maze and tail-suspension paradigms, group 2 for the open-field and forced-swim paradigms, while mice in group 3 were for observation in the conditioned place preference paradigm. Mice in all groups were further assigned into five subgroups (10 males and 10 females), and administered vehicle (distilled water at 10 ml/kg) or one of four doses of MSG (20, 40, 80 and 160 mg/kg) daily for 6 weeks, following which they were exposed to the behavioural paradigms. At the end of the behavioural tests, the animals were sacrificed, and blood was taken for estimation of glutamate levels. The brains were also homogenised for estimation of glutamate levels. Results: MSG was associated with a reduction in locomotion in males and females (except at 160 mg/kg, male), an anxiolytic response in females, an anxiogenic response in males, and decreased behavioural despair in both sexes (females more responsive). Postconditioning MSG-associated place-preference was significantly higher in females. Plasma/ brain glutamate was not significantly different between sexes. Conclusion: Repeated MSG administration alters a range of behaviours in a sex-dependent manner in mice.

The blood glucose- lowering potentials of ethanol leaf extract of Annona muricata were studied. Thirty wistar albino rats were divided into six groups of five rats per group. Group 1 served as “Normal control” animals and received normal rat pellets and water. Diabetes mellitus was induced in Groups 2, 3, 4, and 5 by intraperitoneal injection of alloxan (130 mg/kg). Group 6 rats were administered with 400 mg/kg daily of the extract without induction; group 3 rats were treated with glibenclamide (5 mg/kg body weight), groups 4 and 5 received 200 mg/kg and 400 mg/kg body weight of A. muricata leaf extract daily respectively throughout the duration of the experiment of 14 days. Group 2 rats were induced but not treated with any drug, thus it served as the “Negative control” group. Quantitative phytochemical analysis of the leaf extract was carried out using the Association of Official Analytical Chemists (AOAC) methods. Acute toxicity test of the leaf extract of A. muricata was determined using 12 rats by Lorke’s toxicity testing method. The blood glucose levels of the animals in each group were determined using Accu-chek test strip method. The weights of the animals were determined using a standard electronic weighing balance. The result of the quantitative phytochemical analysis of the leaf showed that the ethanol leaf extract contains the following: phenols (74 mg/100 g), flavonoids (3.70 mg/100 g), tannins (2.95 mg/100 g), oxalate (6.48 mg/100 g), terpenoid (13.88 mg/100 g), phytates (130 mg/100 g), saponins (6800 mg/100 g), alkaloids (570 mg/100 g), cardiac glycoside (1690 mg/100g). Acute toxicity studies showed that LD50 was 3807.89 mg/kg body weight. The results of the average blood glucose levels (mg/dl) of the rats in each group were group 1, 82.6071±7.7524, group 2, 309.3571±163.6923, group 3, 226.7143±132.8182, group 4, 146.5000±140.1465, group 5, 150.4783±81.8340, and group 6, 83.4643±12.5329 for each group respectively. The average body weights of the rats in each group were group 1, 192.8571±22.5844, group 2, 185.7143±33.6759, group 3, 177.1429±36.67500, group 4, 219.2857±21.2908, group 5, 119.5455±23.5993, and group 6, 191.7857±25.2475. The findings from this study suggest that ethanolic leaf extract of A. muricata has notable effect in lowering blood glucose levels in diabetic rats and is a more potent drug in the treatment and management of diabetes mellitus and oxidative stress- related diseases.
