This study investigated the wound healing potential of hexane and methanolic seed extracts of Azadirachta indica using 35 wistar rats that were divided into 5 groups of 7 rats each. Phytochemical screening and antimicrobial activity of the extracts were carried out while the wound healing potential was evaluated by treating the test rats with 5 % and 10 % hexane and methanol extracts in an experiment that lasted for 21 days. Wound area and percentage of wound closure of the rats were noted at four-day intervals and at 21 days, the blood and organs of the rats were subjected to haematological and histopathological analyses respectively. The extracts were found to contain tannins, glycosides and phenols and they inhibited the growth of tested organisms. All the test rats displayed better and faster healing than the control ones but there were no significant differences between their haematological and histophatological results. The seed extracts quickened the wound healing process of the rats and might therefore be useful in wound treatment.

Spirulina platensishas been well-known as an abundant protein and phycocyanin. Spirulina platensis has the effect of anti-inflammatory, so it is widely used to apply cosmetics and biomedicine in the healing process of wounds. To prove that the administration of an extract ofSpirulina platensiscan increase the number of fibroblasts and accelerate the wound healing process in Wistar rats with an incision on their skin. This study used a randomizedpost-test only control group design. The skins of thirty (30) male Wistar rats were incised. This treatment was divided into 4 groups, namely the group that received the 0,1% cream (X1) of S.platensisextract, and the group that was administered with the 0,1% ointment (X2) of S.platensis extract; the negative control group was only treated by a saline solution (C1), and the positive control group was with the administration of Gentamycin 0,1% ointment (C2). The total numbers of fibroblasts were examined on day 14 and calculated using the method of tissue biopsy and hematoxylin-eosin (HE) staining. The wound was checked after 14-day Data analysis was performed with a one-wayANOVA test and was continued by Post Hoc Test LSD. The total numbers of fibroblasts on day 14 from the group of XI, X2, C1, and C2 were 15.00; 17,50; 3,83, 10,33 with p<0.001. The average size of the wounds on day 14 from the groups of X1, X2, C1, and C2 was 551,78; 435,76; 1795,95; 1193,57 with p<0.001, respectively. PostHoc Testresults on the total number of fibroblasts and extensive wound area showed significant differences between them. Administration of the 0.1% ointment of Spirulina platensisextract believed to potentially increasing the number of fibroblasts and accelerate the process of wound healing.

Jatropha neopauciflora is an endemic species of Mexico. Its latex is used to treat wounds, scarring, oral infections, and loose teeth. To date, there are no studies that validate at a morphological level a wound-healing use in diabetes. The present research aimed to evaluate the wound-healing capacity of the latex of J. neopauciflora in the skin of healthy and streptozotocin-induced diabetic mice. Also, a chemical analysis of the latex through molecular exclusion chromatography and HPLC were performed. Male mice ( Mus musculus) of 7-week-old CD1 strain were used. Groups of healthy and diabetic mice were formed. A longitudinal cut of 1 cm was performed on the depilated skin. All treatments were topically applied to the wound area twice a day for ten days. At the end of the experiments, the skin sections were obtained from the wound area and stained with Hematoxylin-Eosin. Then we counted the number of active fibroblasts in all the experimental groups. In normal mice, the latex accelerated the wound-healing process and decreased the number of active fibroblasts, similarly to Recoveron. In diabetic mice, the latex and Recoveron increased the number of active fibroblasts. In normal and diabetic mice, a thin and orderly epidermis was observed. Molecular exclusion chromatography exhibited 58 fractions, 14 of which were subjected to HPLC, to detect catechin, a flavonoid with antioxidant, antimicrobial, and anti-inflammatory properties. J. neopauciflora latex can be useful for wound treatment in patients with diabetes mellitus because it accelerates and promotes the wound-healing process.

Background: Treatment of wounds in diabetes often gets less than perfect healing. One of the reasons for the difficulty in treating wounds in diabetes is the growth of aerobic and anaerobic bacteria. This study aims to determine the pulse voltage and treatment time that can optimally inactivate bacteria, and their effect on wound healing in mice suffering from diabetes. Methods: The study used electrical stimulation with a direct voltage of 10 volts given a pulse voltage of 50-80 volts, a width of 50 µs, and the number of pulses of 65 per second. The research samples were Staphylococcus aureus (S. aureus) and Pseudo-monas aeruginosa (P. aeruginosa) bacteria that grew on beef and mice (Mus musculus) with diabetes. The treatment for S. aureus and P. aeruginosa bacteria was carried out using a pulse voltage of 50-80 volts for 5-15 min/day and repeated for 3 days. Meanwhile, treatment of mice wounds was carried out with a pulse voltage of 80 volts for 15 min/day and repeated for 7 days. Results: The results showed that treatment with a pulse voltage of 50-80 volts and a treatment time of 5-15 min significantly reduced the number of S. aureus and P. aeruginosa bacteria in beef (p£0.05). Treatment with a pulse voltage of 80 volts for 15 min made beef free from bacteria. Meanwhile, treatment with a pulse voltage of 80 volts for 15 min per day for seven days resulted in the wound state of three mice in the maturation phase and two mice in the proliferation phase on day 8 with an average wound area of 0.108 cm 2. Conclusion: The treatment with a pulse voltage of 80 volts for 15 min made the beef sterile, the mice wounds healed quickly, and the mice not stressed. The higher the blood glucose level, the slower the wound healing process.

Epidermal lipoxygenase enzyme extracted from Ambystoma mexicanum (AmbLOXe) is known to accelerate the wound-healing process. AmbLOXe as a protein suffers from inactivation and losing its activity during formulation. Therefore, a delivery system that protects AmbLOXe from inactivation and preserves its activity is needed. We prepared AmbLOXe-loaded pectin nanoparticles (AmbLOXe Pec-NPs) and placed them into an alginate hydrogel. AmbLOXe Pec-NPs incorporation into the alginate hydrogel provides a means for controlled and sustained delivery of AmbLOXe to the wound site. Furthermore, the suitable swelling behavior and mechanical properties of AmbLOXe Pec-NPs alginate hydrogel make it feasible for clinical use. AmbLOXe Pec-NPs alginate hydrogel significantly enhanced the wound-healing process on the rat full-thickness excisional wounds, increased the rate of wound closure, enhanced the re-epithelialization and decreased the incidence of abnormal scarring. AmbLOXe Pec-NPs alginate hydrogel can be proposed as an effective wound hydrogel for improving wound healing with minimal scarring.

The aim of this research is to investigate the wound healing process in in vitro by combining the Manihot esculenta aqueous extract and therapeutic ultrasound. Firstly, the optimization seeding densities of HSF cell 1184 in six-well plate, and then followed by the scratch assay experiment. The scratched that made was treated with the remedial treatments (Manihot esculenta aqueous extract only; ascorbic acid+ therapeutic ultrasound; Manihot esculenta aqueous extract+ ascorbic acid; Manihot esculenta aqueous extract+ therapeutic ultrasound and also the combination of these three materials). The rate of wound closure was observed and analysed at a time interval of 0, 2, 4, 6, 8, 10 and 24 h by using image J software. Then, the cells viability were analysed using the MTT assay. The result showed that Manihot esculenta aqueous extract coupled with specific dose therapeutic ultrasound represents a significantly high rate of wound closure at 96.10 % with the cell numbers at 5.44×105 cells/mL when compared to the other combination therapy. The finding of this study revealed that Manihot esculenta aqueous extract 200 µg/mL and the therapeutic ultrasound specific dose (3 MHz, 300 mWatt/cm2, 50% in 5 min) have the potential in accelerating wound healing process of cells in in vitro.

To explore whether or not inhibition of protein kinase C βII (PKC βII) stimulates angiogenesis as well as prevents excessive NETosis in diabetics thus accelerating wound healing. Streptozotocin (STZ, 60 mg/kg/day for 5 days, i.p.) was injected to induce type I diabetes in male ICR mice. Mice were treated with ruboxistaurin (30 mg/kg/day, orally) for 14 consecutive days. Wound closure was evaluated by wound area and number of CD31-stained capillaries. Peripheral blood flow cytometry was done to evaluate number of circulating endothelial progenitor cells (EPCs). NETosis assay and wound tissue immunofluorescence imaging were done to evaluate the percentage of neutrophils undergoing NETosis. Furthermore, the expression of PKC βII, protein kinase B (Akt), endothelial nitric oxide synthase (eNOS), vascular endothelial growth factor (VEGF), and histone citrullation (H3Cit) were determined in the wound by Western blot analysis. Ruboxistaurin accelerated wound closure and stimulated angiogenesis in diabetic mice. The number of circulating EPCs was increased significantly in ruboxistaurin-treated diabetic mice. Moreover, ruboxistaurin treatment significantly decreases the percentages of H3Cit+ cells in both peripheral blood and wound areas. This prevented excess activated neutrophils forming an extracellular trap (NETs) formation. The expressions of phospho-Akt (p-Akt), phospho-eNOS (p-eNOS), and VEGF increased significantly in diabetic mice on ruboxistaurin treatment. The expressions of PKC βII and H3Cit+, on the other hand, decreased with ruboxistaurin treatment. The results of the present study suggest that ruboxistaurin by inhibiting PKC βII activation, reverses EPCs dysfunction as well as prevents exaggerated NETs formation in a diabetic mouse model; thereby accelerating the wound healing process.

Objective: To assess the effect of bromelain on different aspects of the wound healing process in type 1 diabetic rats. Method: In this study, 112 streptozocin-diabetic (type 1) male Wistar rats were euthanised; 28 each on days three, five, seven and 15, after a wound incision had been made. To estimate changes in a number of different cellular and tissue elements, histological sections were provided from all wound areas and stained with haematoxylin and eosin. Some 1.056mm2 of total wound area from all specimens were evaluated, by assessment of 4200 microscope photos provided from all histological sections, by stereological methods. A biomechanical test of each wound area was performed with an extensometer to evaluate the work-up to maximum force and maximum stress of the healed wound on day 15. Results: In the experimental groups, bromleain caused significant wound contraction and reduced granulation tissue formation by day 7 (p=0.003); increased neovasculars (new small vessels that appear in the wound area during wound healing) on days three, five and seven (p=0.001); significantly increased fibroblasts on day five but decreased by day seven (p=0.002); and significantly decreased macrophage numbers and epithelium thickness on all days of study (p=0.005). Wound strength significantly increased in experimental groups by day 15. Conclusion: Bromelain has a wide range of therapeutic benefits, but in most studies the mode of its action is not properly understood. It has been proved that bromelain has no major side effects, even after prolonged use. According to the results of this study, bromelain can be used as an effective health supplement to promote and accelerate wound healing indices, reduce inflammation and improve biomechanical parameters in diabetic wounds.

Treatment of infected and septic wounds remains one of the most important problems of pediatric surgery. According to the authors, the wound process monitoring affects the treatment outcome not less than operative technique.The objective of the research was to examine the dynamics of microcirculation of the infected and septic wounds in children.Materials and methods. The analysis of the study of infected and septic wounds microcirculation in 178 children was performed. Blood flow laser analyzer (“LAKК-02” RPE “Lazma”, Russia) was used to study the blood flow in the wound area. Monitoring of wound healing process dynamics was conducted by studying the wound healing cytogram.Results. On the first day the average parameter of microcirculation was markedly increased in the area of wound edges in comparison with the contralateral area. The subsequent study of a blood flow during 5 days showed that average value of microcirculation parameter in the wound area decreased by more than 2 times in comparison with the figures on the first day. Microcirculation parameters of in the wound area further decreased.Conclusions. Dynamics of microcirculation changes in wound healing process significantly corresponds to cytogram of impression smears obtained from infected and septic wounds in children. Laser Doppler flowmetry is an effective method microcirculation control and minimally invasive diagnostic method of wound healing process.

The purpose of this study is to evaluate and clarify the effect of Indonesian honey, two types of Japanese honey and hydrocolloid dressing on wound healing process. Four groups of male mice were treated to produce two circular full-thickness skin wounds on the dorsum. They were then randomly allocated to receive daily Indonesian honey, Japanese honey (Buckwheat and Acacia honey) or hydrocolloid dressing as a control for treatment application. Macroscopic findings were observed from day 0 to 14 after wounding. Microscopic evaluation was assessed using qualitative analysis. The ratios of wound areas for honey groups on day 3 and 7 were smaller than those of the control group. Wound areas of honey groups gradually decreased to almost the same wound area as the control group on day 14, while the wound area of the control group peaked on day 5 and rapidly decreased until day 14. Microscopic finding that Indonesian honey was different with Japanese honey especially Buckwheat honey.
