Background: This study evaluated the potential of Ziziphus abysinnica root extract in managing hyperglycaemia in type 2 diabetes mellitus (T2DM), diabetic wound healing and diabetic nephropathy. Methodology: Blood glucose concentrations were measured daily for 14 days after daily administrations of either Ziziphus abysinnica (30, 100, and 300 mg/kg, p.o), metformin (300 mg/kg, p.o) or normal saline as negative control before diabetes induction using a single dose of Streptozotocin (60 mg/kg, i.p) and nicotinamide (120 mg/kg, i.p). Histopathological analysis was performed on the harvested kidneys following administration with Ziziphus abysinnica in diabetic rats. The diabetic wound healing potentials of the plant was also evaluated in streptozotocin-induced diabetic rats by treating them with 15%w/w ZAE ointment. Results: Generally, the percentage of blood glucose levels analysed following administration of drugs were found to be dose-dependent. The highest dose of ZAE (300 mg/kg) had a higher percentage reduction in blood glucose concentration when compared to metformin (300 mg/kg).  The lowest dose (30 mg/kg) of ZAE administered attenuated STZ induced pathological damage and showed moderate to maximal improvement to the kidney nephrons. In contrast, the 100 mg/kg and 300 mg/kg dose ZAE demonstrated minimal pathological changes to the kidney architecture. Conclusion: Overall, our study demonstrated the antidiabetic potential of Ziziphus abysinnica, suggesting its possible therapeutic benefit in diabetic wound healing and diabetic nephropathy.

Objective: This research aimed to evaluate the effect of fractionation of Merremia mammosa Lour. (Mm (Lour.)) extract on diabetic wound healing by observing collagen synthesis process and to search the most potent fraction.Methods: Wistar rats were divided into five groups (n=5), i.e., K-(negative control), K+ (positive control), K1 (ethyl acetate fraction), K2 (water fraction), and K3 (n-hexane fraction). The Mm (Lour.) was extracted with ethanol 70%, then fractionated by using three solvents which have different polarity. The rats were adapted in 7 days, then induced into diabetic by streptozotocin dose 40mg/kg body weight. The wound was made by Morton excision method. Treatment was given every two days and skin biopsy was done on day 11. Analysis of collagen density was done by photomicrograph of histopathology preparations in Masson’s trichome stained by using trinocular microscope with 400x magnification in 6 fields of view, then processed by imageJ software and analyzed by appropriate statistic tool.Result: The results of this research showed that fractionation of Mm (Lour.) extract significantly enhanced diabetic wound healing based on macroscopic (percentage of wound healing) and collagen density with p-value<0.05 when compared with negative control, especially the water fraction (p=0.000). The follow up post hoc analysis showed that there was no­ significant (p=0.989) or there was no meaningful difference in the group of water fraction when compared to positive control.Conclusion: Water fraction is the extract fraction of Mm (Lour.) which has the most significant influence on diabetic wound healing showed by enhancement of collagen synthesis.

Diabetic Wound Healing

A hydrocellular functional material as a wound dressing is developed and it is found to be superior in its efficacy as compared to some of the comparator controls in diabetic wound healing studies. A study on wound contraction and Histopathological analysis is done in rats. The efficacy of the dressing is comparable to the established wound dressings like Carboxymethyl cellulose alginate dressings and autolytic enzyme based hydrogel. It is found to be superior to Polyhexamethylene biguanide dressing used as reference controls in this study. The reason for good wound healing performance of the dressing can be attributed to a combined property of effective exudates management and broad spectrum antimicrobial effect. The concept of functional hydro cellular material has shown good results due to the excellent balance of exudates pickup and drying it out. This ensures moist wound healing conditions on the wound. Because of its porous nature it allows good air flow and gaseous exchange in the structure. The cationic sites created on the surface of the dressing ensure a good antimicrobial action on the exudates in the dressing. It reduces the infection load on the wound. The nonleaching property of the dressing also helps in preventing the generation of more resistant and mutant strains of the microbes. The developed dressing can be used as a relatively durable long lasting dressing for wound management in diabetic wounds. The need of repetitive wound dressing changes can be brought down with this concept of dressing. It is not only cost effective in terms of its material cost but also is a cost effective solution when entire wound management cost is considered. Such novel wound dressing material can change the quality of life of diabetic wound patients especially in developing world, where access to functional advanced wound care dressings is limited.

Aim: Diabetic wound healing is seriously interrupted, and administration of KGF for wound treatment is restricted by its inherent instability. We aim to develop an ideal way toward KGF stabilization, thus improving diabetic wound healing. Materials & methods: We conjugated KGF with gold nanoparticles (GNPs) and determined the stability and binding affinity. Biological effects of conjugates (KGF-GNPs) were evaluated in vitro and in an animal model. Results: KGF-GNPs revealed high stability under hostile circumstances because of the preserved secondary structure and possessed elevated binding affinity to KGF receptor. Moreover, application of KGF-GNPs contributed to accelerated wound recovery in diabetic rats, including re-epithelialization and contraction. Conclusion: KGF-GNPs were promising for future clinical application for diabetic wound therapy.

BACKGROUND: Diabetic micro and macroangiophathy lead to the incident of diabetic foot ulcers characterized by an increased number of circulating endothelial cells (CECs) and decreased function of endothelial progenitor cells (EPCs). This fact is correlated with ischemia and diabetic wound healing failure. Aloe vera gel is known to be able to stimulate vascular endothelial growth factor (VEGF) expression and activity by enhancing nitric oxide (NO) production as a result of nitric oxide synthase (NOS) enzyme activity. Aloe vera is a potential target to enhancing angiogenesis in wound healing.OBJECTIVE: The objective of this study was to explore the major role of Aloe vera gel in wound healing of diabetic ulcers by increasing the level of EPCs, VEGF, and endothelial nitric oxide synthase (eNOS), as well as by reducing the level of CECs involved in angiogenesis process of diabetic ulcers healing.METHODS: The experimental groups was divided into five subgroups consisting of non diabetic wistar rats, diabetic rats without oral administration of aloe gel, and treatment subgroup (diabetic rats) with 30, 60 and 120 mg/day of aloe gel doses for 14 days. All subgroups were wounded and daily observation was done on the wounds areas. Measurement of the number of EPCs (CD34), and CECs (CD45 and CD146) was done by flowcytometry, followed by measurement of VEGF and eNOS expression on dermal tissue by immunohistochemical method on day 0 and day 14 after treatment. The quantitative data were analyzed by One-Way ANOVA and Linear Regression, with a cofidence interval 5% and significance level (p<0.05) using SPSS 16 software to compare the difference and correlation between wound diameters, number of EPCs and CECs as well as the levels of VEGF and eNOS.RESULTS: The results of this study showed that aloe gel oral treatment in diabetic wistar rats was able to accelerate the wound healing process. It was shown by significant reduction of wound diameter (0.27±0.02); the increased number of CECs (0.42±0.57), respectively (p<0.05). On the other hand, the wound diameter and eNOS indicators showed significant differences at the dose of 60 mg, while the number of EPCs and CECs and the level of VEGF showed significantly different results at a dose of 120 mg. Aloe gel oral therapy showed a positive indication of wound healing acceleration at the optimum dose range 60-120 mg a day.CONCLUSIONS: Aloe gel is potential to be a herbal therapy candidate for diabetic wound healing through enhancing EPCs homing, decreasing the CECs number, and stimulating the increase of VEGF and eNOS levels,hence proving to be a dominant factor in the angiogenesis process.KEYWORDS: aloe gel, diabetes, wound healing, angiogenesis

The diabetic wound is the most challenging one to manage, which is associated with microvascular and macrovascular dysfunction, and novel strategies such as using hydrogels demonstrate their promising prospect in treatment and management approaches of the diabetic wound. This study aimed to investigate the effect of collagen/nanoclay/tadalafil hydrogel on wound healing in diabetic rats under HIIT exercise. Hydrogel was synthesized, and then biocompatibility and antibacterial tests were performed. The therapeutic effect of collagen/nanoclay/tadalafil hydrogel was assessed after induction of diabetes in the rat model, and wound healing was evaluated with macroscopic and microscopic tests. The result of the MTT test showed no significant cytotoxicity of collagen/nanoclay/tadalafil hydrogel. Furthermore, the inhibitory effect of hydrogel was detected on E. coli and S. aureus. The macroscopic results demonstrated that the wound contraction was considerable in the hydrogel/HIIT exercise and hydrogel groups compared with the HIIT exercise and control groups during 21 days. The microscopic results showed that the presence of fibroblasts, the amount of collagen, the epidermis density, and the formation of hair follicles were increased in the hydrogel/HIIT exercise group compared with other groups in the diabetic rate model. It can be concluded that collagen/nanoclay/tadalafil hydrogel with HIIT exercise could accelerate diabetic wound healing and can be an appropriate candidate for skin regeneration in medical applications.
