We herein report the anti-diabetic effect of the natural friedelan tritepenoid, 4-oxa-3, 4-secofriedelan (cerin), isolated from cork tissue of Quercus suber L. and its oxygenated derivative, 4-oxa-3, 4-secofriedelan-3-oic acid (cerinox) in streptozotocin (STZ)-induced diabetic rat. Male Sprague Dawley rats were randomized into four groups: non-diabetic control (Group I), STZ-induced diabetic rats (Group II), STZ-induced diabetic rats treated with cerin (Group III), and STZ-induced diabetic rats treated with cerinox (Group IV). Administration of cerin (3mg/kg) and cerinox (3mg/kg) orally to STZ-diabetic rats for three weeks improved the body weight, reduced serum glucose level and activities of alkaline phosphatase, acid phosphatase, glutamate-oxaloacetate transaminase and glutamate-pyruvate transaminase, and restored liver antioxidant status.

The effects of Murraya koenigii leaves are very less studied in streptozotocin-nicotinamide (STZ-NA) induced diabetes rat model, in spite of several studies reported its antidiabetic effects in alloxan and STZ induced diabetes. The present study was undertaken to assess the effects of Murraya koenigii leaves extract on the blood sugar level (BSL) of STZ-NA diabetic rats. Experimental diabetes was induced by STZ injection intraperitoneally (i. p) after 30 min of NA injection i. p in all groups apart from normal control group. Group I (normal control) and Group II (diabetic control) rats received distilled water. Group III rats treated Metformin, Group IV and Group V rats treated Murraya koenigii aqueous extract and Murraya koenigii methanolic extract respectively. BSL and body weights of rats were measured at each week of the period of 28 days. Our results indicate that oral administration of Murraya koenigii reduces BSL significantly compared with the diabetic group. No weight loss was observed in all groups. The findings of the present study suggest that Murraya koenigii is proven as anti-diabetic agent in diabetic rats.

Impaired wound healing is a major concern in diabetic patients due to unregulated chronic hyperglycemia which further may lead to ulcer, gangrene, and its complications. The present study unveils the accelerative effect of aqueous Anthocephalus cadamba leaf extract on wound healing in diabetic rats. Diabetes was induced in 30 Sprague Dawley female rats by using streptozotocin (except control group I) at the dose of 60 mg/kg intraperitoneally. Diabetic rats were randomized in 3 groups viz. diabetic control group (II), diabetes + Kadam plant leaf extract group (III), and diabetes + 5% povidone–iodine solution group (IV). Surgically sterile wound of 1.77 cm2 was created on the dorsal area of anaesthetized rats. The experimental parameters were assessed by hematobiochemical, histopathological, and western blot techniques. The A cadamba extract treatment group (III) (D + KPLE) showed a significant increase in the percentage of wound closure (82%) at day 21 as compared to the diabetic control group (42%), nondiabetic control group (I) (49%), and povidone–iodine treatment group (75%) group (IV). The findings of the present study suggest that the (D + KPLE) group (III) exhibited marked epithelial regeneration, neovascularization, collagen deposition, and fibroblast proliferation along with higher expression of vascular endothelial growth factor as compared to the diabetic control group (II), which was confirmed by histopathological examination and western blot analysis. The present study suggests that the topical application of aqueous A cadamba leaf extract exhibits accelerative wound-healing properties in diabetic rats.

Pharmacological Potential

Objective. The study was designed to evaluate pharmacological potential of hydroalcoholic leaves extract of Chrozophora tinctoria intended for wound healing in diabetic rats’ model. Methods. The method used to evaluate the pharmacological potential of hydroalcoholic leave extract was physical incision rat model. In this model, cutting of the skin and/or other tissues with a sharp blade has been made and the rapid disruption of tissue integrity with minimal collateral damage was observed shortly. Animals used in the study were divided into four groups that consist of six animals in each group. Group I serves as normal control, Group II serves as disease control, Group III was used as standard treatment (Povidone iodine 50 mg/kg b.w.), and Group IV was used for test drug (C. tinctoria 50 mg/kg b.w.). Result. The hydroalcoholic leave extract of Chrozophora tinctoria has been significantly observed to heal the wound (98%) in diabetic rats within 21 days, while standard drug (Povidone iodine) healed the wound about 95% in the same condition. The oral dose (50 mg/kg b.w.) of Chrozophora tinctoria was also found to improve the elevated blood glucose level in comparison to disease control group, which increased after the oral administration of Streptozotocin. Conclusion. The Chrozophora tinctoria has significant wound healing potential in the animal having physically damaged tissue in diabetic condition.

Objective To evaluate and compare the effects of glucose-based solutions to those of icodextrin with respect to peritoneal transport characteristics and formation of advanced glycosylation end-products (AGEs) in the peritoneal membrane in the diabetic rat model of peritoneal dialysis (PD). Study Design Thirty-three male Sprague–Dawley rats weighing between 275 – 300 g were divided into 5 groups: group C ( n = 6), control rats with catheter but not dialyzed; group D ( n = 5), diabetic rats with catheter but not dialyzed; group G ( n = 7), diabetic rats dialyzed with standard 2.5% glucose solution for daytime exchanges and 4.25% glucose solution for the overnight exchange; group H ( n = 8), diabetic rats dialyzed with standard 2.5% glucose solution for daytime exchanges and 7.5% icodextrin solution for overnight exchanges; group I ( n = 7), diabetic rats dialyzed with 7.5% icodextrin solution for all exchanges. Dialysis exchanges were performed three times daily with an instillation volume of 25 mL per exchange for a period of 12 weeks. Tissue sections were stained using a monoclonal anti-AGE antibody. One-hour peritoneal equilibration tests (PET) were performed every 4 weeks for comparison of transport characteristics. Results The level of immunostaining was lowest in group C and highest in group G. Significant differences were seen between group C and groups G, H, and I ( p < 0.001, p = 0.001, and p < 0.05 respectively). Significant differences were also found between group G and groups D and I ( p < 0.05 and p < 0.05 respectively). Over time, glucose concentration at the end of an exchange versus concentration at instillation (D/D0 glucose) decreased and dialysate-to-plasma ratio (D/P) of urea increased. Significant differences were found between groups C and H for D/D0 glucose (0.40 ± 0.01 vs 0.35 ± 0.01, p < 0.05); and between groups C and H for D/P urea (0.87 ± 0.03 vs 0.97 ± 0.02, p < 0.05). Conclusions These results suggest that AGE formation is lower with the use of peritoneal dialysis solution containing icodextrin than with glucose-based solutions. We conclude that the use of icodextrin may be helpful in slowing the deterioration of the peritoneal membrane, prolonging its use for dialysis.

Abstract Aim To investigate the possible beneficial effect of mirabegron [a selective β3-adrenoceptor (AR) agonist] treatment on erectile dysfunction (ED) in streptozotocin-induced diabetic rats. Methods Sprague-Dawley rats (n=20) were divided into two groups: control group and streptozotocin-induced diabetic group. In vivo erectile responses were evaluated after intracavernosal injection of mirabegron (0.4 mg/kg) in rats. The relaxation responses to electrical field stimulation (EFS, 10 Hz), sodium nitroprusside (SNP, 10 nM) and sildenafil (1 μM) of corpus cavernosum (CC) strips were examined after the incubation with mirabegron (10 μM). β3-ARs expression and localization were determined by Western blot and immunohistochemical analyses in CC tissue. Results In vivo erectile responses of diabetic rats [intracavernasal pressure (ICP) / mean arterial pressure, 0.17±0.01] were decreased, which were restored after administration of mirabegron (0.75±0.01, P<0.001). The basal ICP (7.1±0.6 mmHg) in diabetic rats was markedly increased after mirabegron (36.1 ±5.4 mmHg, P<0.01). Mirabegron caused markedly relaxation in diabetic rat CC after phenylephrine precontraction. The relaxation responses to EFS and sildenafil were reduced in diabetic CC, which were increased in the presence of mirabegron. Mirabegron enhanced SNP-induced relaxation response in both groups. The expression and immunoreactivity of β3-ARs localized to CC smooth muscle were observed in control and diabetic rats. Conclusions This is the first study to show that intracavernosal administration of mirabegron improved erectile function and neurogenic relaxation of CC in diabetic rats. These results may be supported by further studies using combinations of mirabegron and phosphodiesterase type 5 (PDE5) inhibitors for the treatment of diabetic ED, especially in patients who do not respond to PDE5 inhibitor therapy.

Background and Purpose. This study aimed to evaluate the wound healing activities of Aftamed and chlorine dioxide gels in streptozotocin-induced diabetic rats. Experimental Approach. Forty-eight Sprague Dawley rats were chosen for this study, divided into 4 groups. Diabetes was induced. Two-centimeter-diameter full-thickness skin excision wounds were created. Animals were topically treated twice daily. Groups 1, the diabetic control group, were treated with 0.2 mL of sterile distilled water. Group 2 served as a reference standard were treated with 0.2 mL of Intrasite gel. Groups 3 and 4 were treated with 0.2 mL of Aftamed and 0.2 mL of chlorine dioxide gels respectively. Granulation tissue was excised on the 10th day and processed for histological and biochemical analysis. The glutathione peroxidase ,superoxide dismutase activities and the malondialdehyde (MDA) levels were determined. Results. Aftamed-treated wounds exhibited significant increases in hydroxyproline, cellular proliferation, the number of blood vessels, and the level of collagen synthesis. Aftamed induced an increase in the free radical-scavenging enzyme activity and significantly reduced the lipid peroxidation levels in the wounds as measured by the reduction in the MDA level. Conclusions. This study showed that Aftamed gel is able to significantly accelerate the process of wound healing in diabetic rats.

The experimental animal study was undertaken to investigate the preventive role ginger juice against hyperglycemia in alloxan induced diabetic rats.Male wistar rats,(130-150)gm wt fed on standard diet and water ad libitum, were divided into 3 groups(n=6) in each group: Group-L non-diabetic control group, Group-II, diabetic control & Group-III, normal rats pretreated with ginger before they were made diabetics. Diabetes was induced by inj. alloxan 150mg/kg body wt.,tp (Group-IL on 2nd day & Group-Ill, on the 9th day).Rats having blood glucose level of more than 7mmol/L on day 5(72 hours after alloxan inj) were considered diabetic & selected for experiment. Rats of Group-Ill received Zingiber officinale (ginger juice) (4m1/kg.body,wt orally) for 7 days (day 2-day8) through Pyles tube before alloxan induction & 3days after the induction. On day 12, animals were sacrificed under light ether anaesthesia, blood was collected by cardiac puncture for blood glucose estimation. Pretreatment with Zingiber officinale (ginger) juice significantly (p<0.01) reduced alloxan induced hyperglycemia.Zingiber officinale (ginger) is one of the most widely used spices and is reputed to have medicinal properties against diabetes mellitus. This study suggests that pretreatment with Zingiber officinale(ginger) prevents the development of hyperglycemia in alloxan induced diabetic rats.

Metformin is now being recognized as the standard therapy in T2D patients who are overweight. Metformin has many drug-disease interactions that can increase the risk of metformin-associated lactic acidosis. Therefore this study was conducted to evaluate any possible pharmacodynamic interactions between metformin and drugs used to treat chronic diseases e.g. Hypertension. The rats were fasted overnight before inducing diabetes with streptozotocin. The rats were given an intraperitoneal injection of streptozotocin (50 mg kg−1) freshly prepared in 0.1M sodium citrate buffer. The diabetic state was confirmed 72 h after streptozotocin injection. Diabetic rats were grouped into seven groups each group of five rats and distributed among the normal control group diabetic control group and the treatment groups. The treatment continued for 10 days. Blood samples were taken before treatment and after 10 days and analyzed for serum glucose, cholesterol, HDL, LDL, and triglycerides. In the diabetic control group which was given STZ alone the blood glucose level decreased significantly (p &lt; 0.05) after 10 days but still above the hyperglycemic level (200mg/dl). The same was observed in the group treated with metformin. The group treated with nifedipine and aspirin showed significant reduction (p &lt; 0.01) in the glucose level below the hyperglycemic level (200mg/dl). While the groups treated with (Metformin + Nifedipine) and (Metformin +Aspirin) showed highly significant reduction (P&lt;0.001) in blood glucose level. These results conclude that the combination of (metformin +Nifedipine) and the combination of (Metformin + Aspirin) have highly significant hypoglycemic effect. It also showed that Nifedipine has promising role in reducing blood glucose level, lipid profile especially LDL-cholesterol, and body weight.
