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.

Uncontrolled blood sugar is a major cause of vascular complications and delayed wound healing in diabetes mellitus. During wound healing process, normally, apoptosis is responsible for events such as removal of inflammatory cells and evolution of granulation tissue into scar which occur during the late phase of wound healing. Early apoptosis can lead to abnormal wound healing by removing granulation tissue including fibroblast, endothelial cell, and small vessels. To determine the role of apoptosis in association with hyperglycemia in diabetic wound healing, apoptosis-related intracellular marker such as expression of Bcl-2 protein by immunohistochemistry and normal histology has been studied. Histological findings show higher level of apoptosis and diminished granulation tissue formation in diabetic rats wounds along with minimal expression of Bcl-2 in diabetic rats wounds when compared with nondiabetic rats wounds. It can be concluded from this study that elevated blood sugar level may be associated with increased apoptosis and the least expression of Bcl-2 protein which might cause deregulation of the wound healing processes in streptozotocin-induced diabetic rats.

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.

The diabetic foot ulcer (DFU) is an invariably common complication of diabetes mellitus, it is also a significant cause of amputation as well as extended hospitalization. As most patients with DFU suffer from malnutrition, which has been related to improper metabolic micronutrients status, alterations can affect impaired wound healing process. Micronutrients and herbal remedies applications present a wide range of health advantages to patients with DFU. The purpose of this review is to provide current evidence on the potential effect of dietary supplementations such as vitamins A, C, D, E, magnesium, zinc, copper, iron, boron, and such naturally occurring compounds as Aloe vera, Naringin, and Radix Astragali (RA) and Radix Rehmanniae (RR) in the administration of lower extremity wounds, especially in DFU, and to present some insights for applications in the treatment of DFU patients in the future.

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.

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.

The Effect of topical application pandan extract gel on gingival wound. Post-gingivectomy wound is usually covered by periodontal dressing, which generally contains some chemical compounds to protect the wound. However, it can provide allergic effect on some patients. Pandan leaves (Pandanus amaryllifolius Roxb.) contain a number of active substances that have anti-inflammatory, antioxidant and antibacterial effect and play a role in wound healing. This study aims to determine the effect of topical application of Pandan leaf extract gel on gingival wound healing. Gingivectomy model was carried out on mandibular incisive gingival using the 2.5-mm punch biopsy. Thirty-six rats were randomly divided into 3 groups of treatment: negative control (CMC-Na), positive control (Aloclair), and 50% of pandan extract gel. The gels on each group were applied (twice in a day) to the wound area after gingivectomy. The observation of the wound healing process was also carried out on day 1, 3, 7, and 14 by making the histological preparations of gingival wound area. The number of blood vessels was observed using microscope and data was analysed using Two- Way Anova and LSD. The result showed that number of blood vessel increased on day 3 and the peak was on day 7. Anova and LSD test showed several significant differences comparison the number blood vessel between treatment and control. In conclusion, topical application Pandan leaves extract gel could accelerate gingival wound healing.ABSTRAKLuka pasca gingivektomi dibalut dengan periodontal dressing yang mengandung senyawa kimia dengan tujuan melindungi luka, namun senyawa kimia periodontal dressing yang ada di pasaran dapat menimbulkan efek alergi terhadap beberapa pasien. Daun pandan wangi (Pandanus amaryllifolius Roxb.) mengandung zat aktif yang memiliki anti inflamasi, antioksidan, dan antibakteri kemungkinan berperan dalam proses penyembuhan luka. Penelitian ini bertujuan untuk mengetahui peran gel ekstrak daun pandan wangi dalam proses penyembuhan luka pasca gingivektomi pada tikus wistar melalui pengamatan jumlah pembuluh darah. Model gingivektomi dilakukan pada gingiva incisivus mandibula dengan menggunakan punch biopsy diameter 2,5 mm. Tiga puluh enam tikus dibagi secara acak ke dalam 3 kelompok perlakuan yaitu kontrol negatif (Gel CMC-Na), kontrol positif (Aloclair), dan gel ekstrak pandan wangi 50%. Gel uji pada masing- masing kelompok diaplikasikan pada area luka pasca gingivektomi dua kali sehari. Pengamatan proses penyembuhan luka dilakukan pada hari ke 1, 3, 7, dan 14 dengan membuat preparat histologi gingiva area luka. Parameter penyembuhan luka yang diamati adalah jumlah pembuluh darah.

Nanostructured lipid carriers (NLC) are capable of encapsulating hydrophilic and lipophilic drugs. The present study developed an NLC containing epidermal growth factor (EGF) and curcumin (EGF–Cur-NLC). EGF–Cur-NLC was prepared by a modified water-in-oil-in-water (w/o/w) double-emulsion method. The EGF–Cur-NLC particles showed an average diameter of 331.8 nm and a high encapsulation efficiency (81.1% and 99.4% for EGF and curcumin, respectively). In vitro cell studies were performed using two cell types, NIH 3T3 fibroblasts and HaCaT keratinocytes. The results showed no loss of bioactivity of EGF in the NLC formulation. In addition, EGF–Cur-NLC improved in vitro cell migration, which mimics the wound healing process. Finally, EGF–Cur-NLC was evaluated in a chronic wound model in diabetic rats. We found that EGF–Cur-NLC accelerated wound closure and increased the activity of antioxidant enzymes. Overall, these results reveal the potential of the NLC formulation containing EGF and curcumin to promote healing of chronic wounds.
