Purpose To investigate the therapeutic effect of local photothermal (PT) heating on suppression of stent-induced granulation tissue formation in mouse colon. Materials and methods A gold nanoparticle (GNP)-coated self-expandable metallic stent (SEMS) was prepared using a two-step synthesis process for local PT heating under near-infrared laser irradiation. Twenty-four mice were randomly divided into two groups of 12 and subjected to SEMS placement in the colon. Group A received a GNP-coated SEMS without local heating and Group B received a GNP-coated SEMS and underwent local heating at 55°C after SEMS placement. The therapeutic effect of local heating was assessed by comparing the histopathological, immunohistochemical, and endoscopic results. Results Four mice were excluded because of stent migration (n = 3, group B) or death (n = 1, group A). Stent-induced granulation tissue-related variables were significantly lower in group B than in group A (p < 0.001). In vivo endoscopic images, 4 weeks after stent placement, showed granulation tissue formation over the wire mesh in group A and relatively good patency of the stented colon with no definite irregularities in group B. There was more vascular endothelial growth factor (VEGF) positivity in group A than in group B. Conclusion Local PT heating suppresses granulation tissue formation after stent placement in mouse colon.

Background: The purpose of our study was to compare the effect of vacuum assisted closure (VAC) therapy and conventional dressings in patients with open wounds due to necrotizing fasciitis (NF) on the basis of healing rate, infection control, frequency of dressing and pain score.Methods: The study evaluated 50 patients admitted with NF requiring surgery over a period      of 18 months.  The patients were randomized to two groups. In group A patients, the wounds were managed with conventional dressings and in group B patients, negative pressure wound therapy (NPWT) was applied. Serial assessment of both groups was done for four weeks. The parameters including size of wound, wound bed, granulation tissue formation, color, amount and odor of exudate, edema, frequency of dressing, re-debridement and pain were monitored and analysed.Results: In our study, patients with NF wounds who underwent VAC therapy had earlier granulation tissue formation, resolution of infection and readiness for skin grafting. The frequency of dressing, requirement of re-debridement, resolution of edema, odor, skin maceration, inflammation around wound and pain significantly reduced in group B (VAC) when compared to conventional dressing group.Conclusions: When compared to the conventional dressing on NF wound, application of VAC helped in early appearance of granulation tissue, significant reduction of inflammation, wound odor, exudate, need for re-debridement, frequency of dressing and pain. Thus, VAC dressing can be considered as a better option in the management of NF wounds.

AIM: To establish the necessity of silicone tube intubation in acute dacryocystitis (AD) patients undergoing endonasal endoscopic dacryocystorhinostomy (En-DCR). METHODS: Patients presenting with unilateral AD were randomly assigned to two treatment groups. En-DCR procedures were performed following lacrimal abscess formation, with the operation being performed with silicone intubation for patients in group B but not group A. Functional success was defined by an absence of additional AD episodes, no epiphora, and ostium patency as established via endoscopic evaluation or fluorescein irrigation. Operative success rates and demographic variables were compared between treatment groups. RESULTS: In total, 66 patients were analyzed in the present study (33 per group), with complete postoperative data having been successfully collected from 27 and 22 patients in group A and group B, respectively. All patients exhibited complete resolution of acute inflammation. Upon follow-up, granulation tissue was detected around the ostium at higher rates in group B (9/22, 40.9%) relative to group A (4/27, 14.8%). At the 12-month follow-up time point, patients in group A exhibited higher success rates (25/27, 92.6%) relative to patients in group B (20/22, 90.9%), but this difference was not significant. Cases of lacrimal passage reconstruction failure in both groups were attributed to excessive fibrous and/or granulation tissue formation proximal to the intranasal ostium. CONCLUSION: Given that these two operative approaches are associated with similar rates of operative success and in light of differences in granulation tissue formation, cost, and operative duration, these data do not support the routine silicone intubation of AD patients following En-DCR surgery.

Wound healing is a complex physiological process consisting of four phases: coagulation, inflammation, proliferation and migration, and remodeling, each with distinct characteristics. Studies have suggested that mangosteen pericarp extract (MPE) may accelerate wound healing. However, the mechanism has not been fully understood. This study aims to evaluate the effect of MPE cream in various concentrations in acute wound healing of albino mice, both histologically and macroscopically. Thirty-two healthy female Swiss albino mice, aged 6-9 weeks, weight 20-30 g, were included in this study. The samples were randomly divided into eight groups each consisting of 4 mice. The first four groups were treated with MPE cream 5%, 10%, and 20%, and no medication (control group), respectively, and were sacrificed after three days. The other four groups received the same application and were sacrificed after 8 days. Wound bed diameter was measured and biopsy from the skin lesion was performed for histopathologic examination. Mann-Whitney test was used to analyze the diameter of the wound bed and histopathological findings of granulation tissue formation, reepithelialization, and inflammation, with P<0.05 considered as significant. MPE cream significantly improved wound healing by increasing granulation tissue formation, and reepithelialization. In addition, MPE cream application was also shown to decrease the number of inflammatory cells, particularly in 5% and 10% concentrations, both in the 3-day and 8-day groups. MPE cream application can accelerate wound healing and thus can be used in acute wound treatment.

Objective.The purposes of our present study were to evaluate the potential of platelet-rich plasma gel to enhance granulation tissue formation after open abdomen and to examine whether the effect was attributable to stimulating rapid neovascularization.Methods.Twenty-four rats underwent colon ascendens stent peritonitis surgery to induce sepsis, followed by intraperitoneal injection of nitrogen to create intra-abdominal hypertension. Four hours later, laparotomies were performed. The rats were randomized into three groups (n=8for each group): control, platelet-poor plasma (PPP), and platelet-rich plasma (PRP) groups. One week after the treatment, granulation tissue formation and angiogenesis were evaluated by histological and laser Doppler analysis.Results.The resultant platelet count in platelet-rich plasma was higher than that of PPP. The concentrations of platelet-derived growth factor BB, transforming growth factorβ-1, and vascular endothelial growth factor in PRP were significantly higher when compared with that of PPP. Myofibroblast count, granulation tissue thickness, vessel numbers, and blood perfusion were increased in PRP group, followed by PPP group, with control being the least.Conclusion.Rapidlyin situforming platelet-rich plasma gel promoted remarkable neovascularization and early wound healing after open abdomen and may lead to novel and effective treatments for open abdominal wounds.

Abstract Minimally invasive therapies using stent technology are currently limited by stent-induced granulation tissue formation adjacent to the stent. The effectiveness of photothermal therapy (PTT) using a gold nanoparticle (AuNP)-coated stent for treating stent-induced granulation tissue formation in the rat esophagus was investigated. All experiments were approved by the animal research committee of our institution. An AuNP-coated, self-expandable metallic stent (SEMS) was produced to conduct PTT under near-infrared laser irradiation. Forty rats were randomly divided into four groups (10 rats each). The animals in group A (non-coated SEMS) and group B (AuNP-coated SEMS with local heating at 65°C at 4 weeks) were sacrificed 4 weeks after stent placement. The rats in group C (AuNP-coated SEMS with local heating at 65°C at 4 weeks) and group D (AuNP-coated SEMS with local heating at 65°C at 4 and 8 weeks) were sacrificed 8 weeks after stent placement. The effectiveness of local heating was assessed by histopathology. All procedures were successful in all of the animals. Seven rats were excluded because of stent migration (n = 2) and death (n = 5). Granulation tissue formation-related variables were significantly higher in group A than in groups B-D (all p < 0.05). HSP70 and TUNEL expression were significantly lower in group A than in groups B-D (all p < 0.05). Granulation tissue formation-related variables were significantly higher in group C than in groups B and D (all p < 0.05). PTT using AuNP-coated SEMS successfully treated granulation tissue formation after stent placement in the rat esophagus.

ackground: This study aimed to compare sheep burnt wool and human amniotic membrane (AM) on second-degree burn wound healing in rats. Materials and Methods: Seventy-two adult male rats of Sprague Dawley underwent general anesthesia, and a deep second-degree burn was created on their skin by a hot iron plate. Afterward, human AM, silver sulfadiazine ointment (SSD), and sheep burned wool were used on wound area for burn treatment. On days 7, 14, and 21 of the experiment, the rats were sacrificed, and histopathological assessments were done. Results: Human AM, in comparison with other groups, significantly (P<0.05) showed better improvement in all pathologic variables. Burned wool showed significant improvement compared to the control group on day 7 in the angiogenesis, on day 14 in granulation tissue formation and epithelial formation, and on day 21 in new epithelial formation (P<0.05). Burned wool compared with SSD ointment in granulation tissue formation improved significantly (P<0.05) on days 7 and 14. Also, SSD ointment in comparison with the control group significantly improved (P<0.05) granulation tissue formation and macrophage on day 7. Conclusion: Human AM has a significant effect on the treatment of second-degree burn. Burned wool has a better effect on wound healing than SSD ointment and negative control group without treatment in terms of granulation tissue and epithelium formation. [GMJ.2020;9:e1759]
