Recent clinical studies have shown that adjuvant chemotherapy may improve response rates to treatment for advanced head and neck carcinomas. Given preoperatively, some chemotherapeutic agents adversely affect wound heallng. The specific purpose of this study was to evaluate the Influence of cisplatin on wound healing when it is given preoperatively. Forty-four Swiss outbred mice were divided into control and treatment groups. One week before surgery, the treatment group received cisplatin (2 mg/ kg body weight) by subcutaneous injections on 2 consecutive days. Each control animal was given an equal volume of normal saline. A 1.5 cm transverse incision was made in each animal, and wounds were closed with surgical staples. The mean woundbreaking strength was determined for a minimum of 5 treatment and 5 control mice on postoperative days 6, 10, 13, and 16. Serum creatinine, blood cell counts, and changes in weight were also monitored. Results showed wound strength on postoperative day 10 to be significantly reduced in mice treated with cisplatin (P < 0.05). There was no significant difference for wound strength on any other days and all other variables were simllar between both groups. In conclusion, cisplatin has an adverse effect on wound healing, the peak of which probably occurs during the proliferative stage of wound healing. Further studies are needed to determine the optimal time for surgery after preoperative chemotherapy. All new chemotherapeutic agents, particularly those being considered in a preoperative regimen, should be tested in this manner.

Abstract Background: Chemical trauma to the cornea is an emergency condition of the eye that requires early diagnosis and good treatment. Alkaline have ability to saponify fatty acids in cells and cell membranes which can make penetration into the stroma and destroy proteoglycans and collagen in cells. Aloe vera (AV) contains several active substances that are reported to have anti-inflammatory, immunomodulatory, and wound healing effects. AV has been reported to accelerate the healing process of corneal epithelial defects by increasing fibroblast proliferation, collagen production and growth factor production. This study aims to determine the difference between the effect of aloe vera extract with a concentration of 10%, 20%, 40% and BSS on the healing of extensive corneal lesions in white wistar rats alkaline trauma models. Method: This study was an experimental study with a pre and posttest only with control group design in vivo approach to 30 Wistar white rats which were divided into 5 treatment groups for 3 days. Comparative analysis of effectiveness using the ANNOVA test or the Kruskal Wallis test and continued by the post hoc test. Results: Based on the one way ANOVA test there was a statistically significant difference in effectiveness between the five treatment groups on the percentage of corneal wound healing area and TGF-β expression with an assessment of p = 0,000 each. The administration of alloevera (AV) concentration of 20% had a significant difference in percentage of healing of corneal lesions and TGF-β expression compared with other treatment groups with p = 0,000 each. Large differences in the area of corneal lesions in the 40% AV group were -0.45 in the BBS group, 0.146 in the 10% AV group, 0.493 in the 20% AV group. The difference in the AV group 10% was 0.30 in the BBS group, -064 in the AV group 20%, and -0.14 in the AV group 40%. However, TGFβ expression in the normal control group that did not receive treatment was 54.94 (53.21-56-12). TGFβ levels in the BSS group were 10.44, the 10% aloe vera group was 25.43, 47.99 for the 20% aloe vera group and 37.95 for the 40% aloe vera group. Conclusion: There is a difference between the effect of aloe vera extract with concentrations of 10%, 20%, 40% and BSS on the extensive healing of corneal lesions in white wistar rats with alkaline chemical trauma models.

The sap of ambonese banana (Musa paradisiaca var sapientum) contain flavonoids, saponins, tannins which have beenwidely used by people in Trunyan Bali as traditional medicine on wound healing, and it has been reported as apotential wound healing after tooth extraction. The aim of this research was to determine the level of safety of usingherbal medicine, ambonese banana stem extract on histopatology liver of mice with LDparameters. This experimentalstudy was performed bythe post test only controlled group design. The sample were 28 mice (Mus musculus) randomlydivided into 4 groups. K group as control group was given aquadest. P1, P2, and P3, as treatment groups were givenambonese banana stem extract with dose 0.42g/20gbw, 2.1g/20gbw, 4.2g/20gbw. The extract was given per-oral withsonde on the first day. On day 3, the mice were terminated, and the livers were microscopically histopathological observed. The observed at 3th50 day, there were no deaths in every groups of mice (K, P1, P2, and P3) on the third day observation. Kruskal Wallis test showed there was not significant difference in histopathological appearance on liverof mice (p=0.771). It wasconcluded that the maximumsafety dose that can still be administered is 0.42g/20gbw followingthe LDparameter. Theacute toxicity test of ambonese banana stem extract did not show necrosis on liver but it showedthe highest simple degeneration than all groups which were given 0.42g/20gbw dose.

Purpose To evaluate and compare the effectiveness of two adhesion barriers, Interceed and Seprafilm, on wound healing reaction after glaucoma filtration surgery. Materials and Methods Full-thickness filtration surgery was carried out on three groups, each containing four rabbits. Interceed and Seprafilm prepared in 3×4 mm dimensions was put on and around scleral opening in Groups 1 and 2, respectively. All groups received tobramycin and dexamethasone drops tid for 14 days. Intraocular pressure (IOP), anterior chamber depth, and bleb appearance were checked on the first, third, seventh, and 14th days. The rabbits were killed on the 14th day and the trabeculectomy area with overlying conjunctiva was excised. The samples were fixed with 10% formalin, buried in paraffin, and stained with hematoxylin and eosin. The surgical site and surrounding subconjunctival area were evaluated histopathologically for cell counts (fibroblast, lymphocyte, eosinophil, and macrophage), presence of edema and foreign body reaction, and potency of the fistula tract. Results Mean IOP at the first and third day examinations was significantly different between groups, but there was no statistically significant difference among the groups with respect to IOP, anterior chamber depth, or bleb appearance at the seventh and 14th days. The groups were similar with respect to number of fibroblasts, eosinophils, and neutrophils. Number of macrophages was significantly increased in Groups 1 and 2 and number of vessels was significantly decreased in Group 1. Conclusions Neither of these two adhesion-preventing substances seems to suppress wound healing reaction after glaucoma filtration surgery. However, a diminished wound healing reaction was expected with a decreased number of vessels, such as in Group 1. Increased number of macrophages in both groups may result in a decreased level of some inflammatory mediators.

Aims: Chitosan and epidermal growth factor (EGF) have been shown to improve wound healing. This study investigates the healing effects of a spray solution (NewEpi, JoyCom Bio-Chem Co. Ltd., Taiwan) containing recombinant human EGF (rhEGF) delivered via a newly patented technology—chitosan microencapsulated nanoparticles. Methods: On Wistar rats, two full-thickness wounds on the dorsum bilateral of the spine were created. The rats were randomised to the following treatment groups: hydrogel, wet dressing, foam, rhEGF spray and rhEGF spray+foam. Sterile dressings were applied and changed daily. A total of 2μg of rhEGF was administered in two sprays during each dressing change. All animals were euthanised on day 14. Tissue samples were taken from the wound bed, including an area of 2cm surrounding the wound margin for histological evaluations. Results: Wounds treated with the rhEGF spray achieved the greatest size reduction by day 14 compared with other types of conventional dressings. An overall significant difference in levels of collagen synthesis existed between groups (p<0.01). Pair-wise comparisons showed that the rhEGF spray treatment significantly promoted higher levels of mature Type I collagen than any other conventional dressings (p<0.01), whereas non-rhEGF treatments resulted in higher levels of Type III collagen. The regenerated tissue in rhEGF spray treatment groups was also in alignment with that of normal skin. Epidermis, dermis and hair follicles were easily observed in wounds treated with the rhEGF spray. Conclusion: The major challenge of topical application of rhEGF was overcome by using a new drug delivery technology: chitosan–rhEGF nanoparticles. The positive healing effects observed in this study suggest the therapeutic potentials of this novel rhEGF topical spray solution.

Aims Pin-site infection remains a significant problem for patients treated by external fixation. A randomized trial was undertaken to compare the weekly use of alcoholic chlorhexidine (CHX) for pin-site care with an emollient skin preparation in patients with a tibial fracture treated with a circular frame. Methods Patients were randomized to use either 0.5% CHX or Dermol (DML) 500 emollient pin-site care. A skin biopsy was taken from the tibia during surgery to measure the dermal and epidermal thickness and capillary, macrophage, and T-cell counts per high-powered field. The pH and hydration of the skin were measured preoperatively, at follow-up, and if pin-site infection occurred. Pin-site infection was defined using a validated clinical system. Results Out of 116 patients who were enrolled in the study, 23 patients (40%) in the CHX group and 26 (44%) in the DML group had at least one bad or ugly pin-site infection. This difference was not statistically significant (p = 0.71). There was no significant relationship between pH or hydration of the skin and pin-site infection. The epidermal thickness was found to be significantly greater in patients who had a pin-site infection compared with those who did not (p = 0.01). Skin irritation requiring a change of treatment occurred in four patients (7%) using CHX, and none using DML. Conclusion We found no significant difference in the incidence of pin-site infection between the CHX and DML treatment groups. Dermol appeared to offer a small but significant advantage in terms of tolerability. We did not find a significant association between patient or treatment related factors and pin-site infection. It is therefore difficult to make specific recommendations based upon these results. The use of either cleaning agent appears to be appropriate.

This study was conducted to prove whether ellagic acid can be used as a regulator of incision wound healing process in male albino rats as experimental animals. A total of 24 male healthy rats based on physical examination, aged at 3 months old and weight at 150-180 grams used in this study. Rats were divided into three groups and each group has 8 replications, group of control (P0) has no incision wound and no medication, treatment group (P1) has incision wound and treated with Betadine® and (P2) has incision wound and treated with 2,5 % ellagic acid. The variable that observed are histopathology changes (collagen, PMN, angiogenesis and fibrosis) from the male albino rats. The samples collection was taken at day 15 and data were collected and analyzed by Analysis of Variance (ANOVA) test. The result of collagen and PMN cells score in the control group (P0) were 1.80 ± 0.16 and 1.6 ± 0.08 with mild angiogenesis and no fibrosis. The results in the treatment (P2) group, where the collagen and PMN scores were 1.60 ± 0.08 and 1.5 ± 0.8, accompanied by mild angiogenesis and fibrosis. Meanwhile, in the treatment (P1) group, the results of scoring of collagen and PMN were lower than the other groups, 0, 80 ± 0.08 and 0.6 ± 0.16 accompanied by moderate angiogenesis and fibrosis. There was a significant difference of collagen scoring, PMN cells number, fibrosis and angiogenesis among the treatment groups (p<0.05). P1 treatment group has significant different with treatment groups P0 and P2 (p<0.05), but there is no significant difference between treatment groups P0 and P2 (p>0.05).  From the results, it can be concluded that the topical application of ellagic acid ointment was proved to provide healing process on incision wound. Topical administration of ellagic acid ointment for 14 days was able to improve the skin condition and promoted the wound healing.Keywords: Ellagic acid ; wound healing ; collagen ; angiogenesis ; fibrosis ; anti-inflammatory ; antioxidant ; antibacterial.

Background and objective: To study the time-dependent effects of ischemia – reperfusion on myocardium cells. Methodology: Male SD rats (270-330gr) were randomly grouped in four groups of 10 in an experimental study. After anesthesia using pentobarbital sodium (50-60 IP-kg/mg) the rats’ hearts in the treatment groups were isolated immediately and connected to langendorff apparatus with krebs solution at 37ºC and a fixed pressure. During stabilization, 30m ischemia and 60, 90, and 120min reperfusion was carried out on the hearts. Hearts of the control group remained intact. Immunhistochemistry of apoptotic cells was performed using TUNEL POD Kit and positive TUNEL myocardium cells of each group, in five microscopic view fields, was counted. The results were represented as mean ± SD. Findings: Apoptotic cell counts in control group was 1±0.4, and this figure in the treatment groups T/60min, T/90min, and T/120min was 2.0±0.5, 3.0±0.3, and 6.0±0.3 respectively. Comparison between the treatment groups and control group was carried out using one-way ANOVA and the results showed no significant difference between the groups T/90min and T/120min and the groups T/60 and control (p>0.05). However, the differences between the groups T/120min and T/60min (p<0.001) and groups T/120min and T/90min (p<0.01) was significant. Conclusion: The study showed that ischemia-reperfusion time can be effective on apoptotic changes of myocardium cells of heart.
