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.

Objective: To assess the wound healing potential of Pimpinella anisum on cutaneous wounds in diabetic rats. Method: Full-thickness excisional wounds were made on the back of male, Sprague-Dawley rats with diabetes. The rats were randomly allocated into four treatment groups: 1ml basal cream; tetracycline (3%); Pimpinella anisum 10% for 14 days; and a control group. At days seven, 14 and 21 post-injury, five animals of each group were euthanised, and wounds were assessed through gross, histopathological and oxidant/antioxidant evaluations. Additionally, the dry matter and hydroxyproline contents of the skin samples were measured. Results: A total of 60 rats were used in the study. A significant decrease in the wound size was observed in treated animals with Pimpinella anisum compared with other groups during the experiment. Additionally, treatment with Pimpinella anisum decreased the number of lymphocytes and improved the number of fibroblasts at the earlier stages and increased a number of fibrocytes at the later stages of wound healing. Other parameters such as re-epithelialisation, tissue alignment, greater maturity of collagen fibres and large capillary-sized blood vessels revealed significant changes when compared with the control. Pimpinella anisum significantly reverted oxidative changes of total antioxidant capacity, malondialdehyde and glutathione peroxidase induced by diabetic wounds (p<0.05). Furthermore, it significantly increased the dry matter and hydroxyproline contents at various stages of wound healing (p<0.05). Conclusion: The present study showed that application of Pimpinella anisum extract promotes wound healing activity in diabetic rats. The wound-healing property of Pimpinella anisum can be attributed to the phytoconstituents present in the plant.

AbstractAimThe present study aimed to examine the effects of melatonin supplementation on lipid peroxidation in the bone tissue of diabetic rats subjected to acute swimming exercise.MethodsThe study was conducted on 80 Sprague-Dawley type adult male rats which were equally allocated to eight groups: group 1, general control; group 2, melatonin-supplemented control; group 3, melatonin-supplemented diabetic control; group 4, swimming control; group 5, melatonin-supplemented swimming; group 6, melatonin-supplemented diabetic swimming; group 7, diabetic swimming; group 8, diabetic control. In order to induce diabetes, the animals were subcutaneously injected with 40 mg/kg streptozotocin (STZ). The animals were supplemented with 3 mg/kg/day melatonin intraperitoneally (IP) for 4 weeks. At the end of the study, the animals were decapitated to collect bone tissue samples which were examined to find out the malondialdehyde (MDA) (nmol/g/protein) and glutathione (GSH) (mg/dL/g protein) levels.ResultsThe highest MDA values in the bone tissue were found in groups 7 and 8. MDA levels in the bone tissue in groups 3 and 6 were lower than the levels in groups 7 and 8, but higher than those in all other groups. Groups 3, 5 and 6 had the highest bone tissue GSH values. On the other hand, the lowest GSH level was established in groups 7 and 8.ConclusionThe results of the present study indicated that the cell damage caused by acute swimming exercise and diabetes in the bone tissue could be prevented by melatonin supplementation.

Introduction: Leaves of mempelas paya (Tetracera indica) (family: Dilleniaceae) is traditionally used in diabetes management in Malaysia. However, no attempt has ever been made to discover an active principle responsible for its blood glucose lowering effect. Hence, this research deals with the isolation, in vivo antidiabetic and toxicological evaluation of an active principle. Methods: Chemical investigation of methanol extract derived from the powdered leaves resulted in the isolation of a phenolic compound through repeated silica gel column chromatography. The structure was elucidated by spectroscopic (1H-NMR, 13C-NMR, MS, IR and UV) analysis. In vivo antidiabetic and toxicological studies were carried out using Sprague-Dawley rats (diabetic and normal) at three different concentrations (1, 5 and 25 mg/kg b.w.). Results: 5,7-dihydroxy-8methoxyflavone was found to exhibit significant anti-hyperglycaemic activity (p<0.05) in diabetic rats at 5 and 25 mg/kg b.w. without showing hypoglycaemic effect in normal rats. The anti-hyperglycaemic activity was found to be comparable with glibenclamide (GLBC) (p<0.05). In vivo toxicological study for continuous 21 days showed no abnormal activity and mortality. Histopathology of kidney, liver and pancreas of both normal and diabetic treated rats demonstrated normal and improved condition when compared to diabetic control group. There were no significant changes seen in the kidney (serum urea and creatinine) and lipid (TC, TG, LDL-C and HDL-C) functional parameters tested. Conclusions: 5,7-dihydroxy-8-methoxyflavone isolated from the leaves of mempelas paya coud be a safe antidiabetic agent.

Citrullus vulgaris Schrad, commonly known as “watermelon” and Chrysophyllum albidum G., commonly called ‘‘Udara’’ are two important plants known to possess high antioxidant and therapeutic properties especially antidiabetic properties. The present study is aimed at investigating the blood glucose lowering potentials of both the aqueous and ethanolic extracts of the mixture of rinds of C. vulgaris Schrad and C. albidum in normal and alloxan-induced-diabetic rats. Aqueous and ethanol rinds extracts of the mixture were administered in wistar albino rats of weight range of 150-200g to determine their blood glucose lowering activity. The oral administration of aqueous mixed rinds extracts at dose of 1500 mg/kg body weight (Group 4) for 9 days led to a highly significant blood glucose reduction at P<0.05 when compared to the diabetic control (Group 2) and the ethanol mixed rinds extracts at the same dose (Group 6). There was a significant reduction in blood glucose (P<0.05) by other group dose extracts (Groups 3,5 and 6) compared to diabetic control. Hence, aqueous mixed rinds extracts of Citrullus vulgaris Schrad and C. albidum might be recommended as a potential hypoglycemic drug in the treatment of diabetes mellitus.

We explored the effects of topical curcumin on the healing of nasal mucosal wounds. A total of 32 Sprague-Dawley Albino rats were randomized in equal numbers into four groups, and unilateral nasal wounds were created using an interdental brush. Group 1 (the sham-control group) contained untreated rats with traumatized right-side nasal cavities; Group 2 and 3 rats were similarly traumatized and treated with topical curcumin (5 and 10 mg/mL) dissolved in dimethyl sulfoxide daily for 7 days after trauma; Group 4 rats were treated with topical dimethyl sulfoxide only. All rats were decapitated on day 15 and the healing sites evaluated by blinded observers in terms of the presence of cellular hyperplasia, goblet cell hypertrophy and degeneration, leucocytic infiltration, ciliary loss and degeneration, edema, and vascular dilation. On histopathological evaluation, all of cellular hyperplasia, leukocytic infiltration, and edema were significantly reduced in Group 3 compared with Group 1 (p=0.001, p=0.004, and p=0.008, resp.). Thus, curcumin reduced the inflammatory response and significantly accelerated wound healing.

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.
