Foram utilizados seis eqüinos adultos sem raça definida (SRD), com o objetivo de estudar os aspectos macroscópicos e histopatológicos da cicatrização de pele por segunda intenção, em feridas provocadas cirurgicamente e tratadas topicamente por fitoterápicos: barbatimão (Stryphnodendron barbatiman), calêndula (Calendula officinalis) e confrey (Symphytum officinale), tendo a solução salina como controle das demais. Foram feitas quatro lesões de cada lado da região lombar, do lado direito destinadas à macroscopia e do lado esquerdo à análise histopatológica. As lesões foram tratadas diariamente, observando-se a evolução de cada ferida quanto à retração centrípeta e aspecto macroscópico, até a cicatrização completa. Finalizado o experimento, a análise estatística não revelou variações significativas no estudo comparativo dos fitoterápicos. As observações macroscópicas, histopatológica e a retração centrípeta do halo da lesão nos 15 primeiros dias permitiram concluir que o barbatimão revelou efeito benéfico no processo de cicatrização, seguido pela calêndula, sendo os resultados do grupo controle superiores ao confrey. Comparison between phytotherapics on equine wound healing Abstract It has been carried out a study on the macroscopic and histopathologic aspects of equine skin healing by second intention in wounds cirurgically performed and topically treated with phytotherapics: barbatiman (Stryphnodendrom barbattiman), calendula (Calendula officinalis) and confrey (Symphytum officinale) and physiological solution as control. Four lesions were performed in each side of the lumbar area: the ones in the right side for macroscopic observations and the ones on the left side for histopathologic analysis. The lesions were daily treated with the above mentioned phytotherapics. Each wounds was observed in regard to its centripetal contraction and macroscopic aspects until the complete healing. In this model, the statistic analysis did not reveal significant variations in regard to the comparative effect of the phytoterapics. Macroscopic observations, histopathologic analysis and wound area centripetal retraction in the first fifteen days displayed a beneficial effect of barbatiman in the healing process, better than the other treatment groups, followed by calendula. The results displayed by the control group showed to be superior when compared with confrey.

ABSTRACT Background: Manipulating intestinal microbiota with probiotics might stimulate skin response. Understanding all stages of the healing process, as well as the gut-skin-healing response can improve the skin healing process. Aim: To evaluate the effect of perioperative oral administration of probiotics on the healing of skin wounds in rats. Methods: Seventy-two Wistar male adult rats were weighed and divided into two groups with 36 each, one control group (supplemented with oral maltodextrin 250 mg/day) and one probiotic group (supplemented with Lactobacillus paracasei LPC-37, Bifidobacterium lactis HN0019, Lactobacillus rhamnosus HN001, Lactobacillus acidophilus NCFM® at a dose of 250 mg/day), both given orally daily for 15 days. The two groups were subsequently divided into three subgroups according to the moment of euthanasia: in the 3rd, 7th and 10th postoperative days. Results: There were no significant changes in weight in both groups. Wound contraction was faster in probiotic group when compared to the controls, resulting in smaller wound area in the 7th postoperative day. As for histological aspects, the overall H&E score was lower in the probiotic group. The probiotic group showed increased fibrosis from 3rd to the 7th postoperative day. The type I collagen production was higher in the probiotic group at the 10th postoperative day, and the type III collagen increased in the 7th. Conclusion: The perioperative use of orally administrated probiotic was associated with a faster reduction of the wound area in rats probably by reducing the inflammatory phase, accelerating the fibrosis process and the deposition of collagen.

Aim of the study: Is to evaluate the effect of myrrh oil local application on the healing process of skin wounds histologically , histomorphometrically and , histochemically. Materials and methods:Twenty male white New Zealand rabbits were used in this study. An incisional wounds with full thickness depth and of 2 cm length were done on both sides of the cheek skin of each rabbit. The left sided incisions (the control group) were irrigated with distilled water (10µL). The right sided incisions (the experimental groups) were treated with myrrh oil (10µL). Each group was subdivided into 4 subgroups according to the healing interval into 1,3,7 and 14 days(5 rabbits for each group). Results: Histological findings of our current study showed a highly significant difference between the experimental and the control groups in count of the inflammatory cells which showed that mean values increased with time for the control and the experimental groups. The histomorphometrical findings had shown that the thickness of the epithelium was nearly completed at about 7 days for the experimental groups and at about 14 days for the control. The blood vessels count was recorded to have a highly significant difference between the groups at days 1 and 3 only. The histochemical findings had shown that the collagen fibers remodeling had recorded a highly significant difference between the control and the experimental groups at days 7 and 14. Conclusion: The current study had revealed that myrrh oil accelerates wounds healing in rabbits. Key word:Wound healing , Myrrh oil, Masson’s Trichrome staining.

Corticosteroid Injections

Background: Corticosteroid injections in or around tendons for the treatment of athletic injuries are a common practice among orthopaedic surgeons and are apparently efficacious in the short term, although controversies persist related to local complications. Purpose: This study evaluated short-term (48 hours) biomechanical, biochemical, and histological alterations after a single injection of betamethasone into the normal tendons of rabbits. Study Design: Controlled laboratory study. Methods: A total of 72 New Zealand White rabbits were randomly divided into 2 groups: the test group—in which 36 animals underwent 1 intratendinous injection of betamethasone (1.4 mg / 0.2 mL) in the right calcaneal tendon; the control group—in which the right calcaneal tendon of 36 animals was injected with saline (placebo control group) and the left calcaneal tendon was left untreated for normal standards (normal control). Forty-eight hours later, animals were euthanized and tendons were harvested. Metalloproteinase (MMP1 and MMP2) and interleukin (IL1 and IL6) expression levels, biomechanical resistance (load × elongation parameters), and histomorphometry (hematoxylin and eosin and picrosirius red stains for collagen fibers, tenocytes, and inflammatory cells) were analyzed in the tendons. Results: The test group had a significant reduction in MMP2 expression as compared with the control groups ( P = .027). Regarding the other parameters, there were no additional significant differences between the groups. Conclusion: A single injection of corticosteroid into normal calcaneal tendons did not trigger acute local morphological, structural, or biomechanical injuries at 48 hours, but it did promote a significant decrease in MMP2 levels. Additional studies are needed with increased duration of follow-up, various doses, and multiple injections and in tendinopathic models. Clinical Relevance: Some previous studies demonstrated early structural changes in tendons after a single corticosteroid injection, which was not corroborated by the present study. Metalloproteinase decrease is usually associated with a reduction in collagen degradation, which would be protective for the healing process. More studies are necessary to confirm the possible beneficial effect of these results in the long term and for tendinopathies.

Objective: Diabetic foot ulcers (DFU) are often hard-to-heal, despite standard care. With such a complicated healing process, any advanced wound care to aid healing is recommended. Chitosan/collagen composite hydrogel materials have the potential to promote the regenerative process. In this study, the efficacy of a new collagen matrix dressing including chitosan/collagen hydrogel was compared with a standard dressing of saline-moistened gauze for wound healing in patients with a hard-to-heal neuropathic DFU. Method: This is an open labelled, randomised clinical trial. After conventional therapy consisting of debridement, infection control and offloading, patients were randomly allocated to receive either a collagen matrix dressing (the study group, receiving Tebaderm manufacturer) or a saline-moistened gauze dressing (control group) for wound care. The reduction in DFU size and the number of patients with complete healing were measured throughout the treatment and in follow-up. Results: A total of 61 patients with a neuropathic DFU were recruited. Average percentage reduction in DFU size at four weeks was greater in the study group compared with the control group (54.5% versus 38.8%, respectively). Rate of complete healing rate at 20-weeks' follow-up was significantly better in the study group than the control group (60% versus 35.5%, respectively). Conclusion: The collagen matrix dressing used in this study accelerated the healing process of patients with a hard-to-heal DFU. Further research may suggest the used of this dressing to shorten the length of time to achieve complete healing.

Abstract Background and Purpose: Burns are one of the most common injuries. There are few medications to repair skin in burns. Although antibacterial drugs such as topical silver sulfadiazine may prevent wound infections, they usually can’t attenuate skin healing. Marshmallow is used in Iranian traditional medicine to improve skin burns. We aimed to evaluate the effect of hydroalcoholic and aqueous extract of Althaea officinalis on the histopathologic parameters of second- and third-degree burns in mice. Experimental approach: The mice were randomly divided into 9 groups (n=6) including control and treatment groups. Experimental second- and third-degree burns were induced on dorsal skin of the mice by a metal plate (2 cm in diameter) under general anesthesia. Control and treatment groups were treated twice daily for 21 days topically. Normal saline was used for control group and hydroalcoholic and aqueous extracts of Althaea officinalis in three concentrations (1%, 2% and 4%) were used for the treatment groups. All of the preparations were made in hydrogel base. Finally, the histopathological parameters of the burned skin including polymorphonuclear (PMN) migration, epithelialization, angiogenesis and collagenization were scored and total score of wound healing was calculated. Key Results: The findings showed that topical application of both hydroalcoholic and aqueous extracts of Althaea officinalis attenuates the wound healing process. they reduce PMN migration, collagenization, epithelialization and angiogenesis scores compared to control group. Conclusions & Implications: Althaea officinalis can be used as an adjunct medication to attenuate wound healing in skin burns.

PURPOSE: To assess vthe action of iodine cadexomer in the healing process of surgical wounds in rats and if cytotoxicity occurs with the systemic absorption of iodine. METHODS: Thirty six Wistar rats were used and performed 53 wounds with surgical punch of 6 mm diameter on them. Two lesions were made diametrically opposed on groups with distilled water (GAD) and sodium chloride (GCS); on the right lesions were used bandage with distilled water and on the left ones dressing with sodium chloride. In cadexomer iodine (GCI) group, a punch injury was made only on the left side and the dressing was carried out with cadexomer iodine. The groups were divided in two sub-groups according to the day of death (7 and 14). Microscopically was used H&E staining, through which the inflammation could be observed and also the neovascularization. Staining with Masson trichrome studied fibrosis. TSH and free T4 were used for absorption recognition of iodine, and its toxic potential was performed before death with the animal anesthetized. RESULTS: Microscopic analysis showed more marked intensity of inflammation in group GAD, subgroup 14 days. Neovascularization showed be discrete in GCS sub-group 14 days. Fibrosis was more pronounced in the group GCI. Comparing the types of treatment, there was statistical significance between groups GCI and GCS (p<0.013). The TSH and T4, showed no difference between the control group and GCI in relation to the absorption of iodine. In evaluating the GCI and control groups, within each treatment, statistical significance was found between them (p<0.001) when compared the days of observation. CONCLUSION: Cadexomer iodine had beneficial effects in all phases of the healing process without cytotoxicity due iodine absorption.

PURPOSE: To evaluate the morphological aspects of the behavior of 4 types of latex biomembranes implanted in preperitoneal videolaparoscopic inguinoplasty. METHODS: Sixteen inguinoplasties were performed in 12 dogs: group 1 received an impermeable latex biomembrane in the right inguinal region and a prolene prosthesis, as control, in the contralateral inguinal region; groups 2, 3 and 4 received latex biomembranes respectively containing impermeable polyamide, 1-mm thick porous polyamide and 0.5-mm thick porous polyamide. Macro- and microscopic evaluations of the inguinal region and of the removed implants were made on the 7th, 14th, 21st and 28th days in group 1 and on the 28th postoperative day in the other groups. RESULTS: We observed absence of hematoma, seroma and infection; presence of tortuosities; induction of vascular neoformation, inflammatory reaction and collagen deposition, and full encystment of the latex biomembranes, except that with fine porous polyamide, which was partially incorporated, with the formation of microcysts. No latex biomembrane induced fibrosis as observed in the prolene control group. CONCLUSIONS: The biomembranes maintain induction of the healing process without fibrosis, are fully encysted and, except for the one with fine porous polyamide, are not incorporated into adjacent tissues. The latex biomembrane, with or without polyamide, is not recommended as a separate material for preperitoneal inguinoplasty.

Abstract: Coffee is known as food and drink as well as alternative medicine for various types of wounds. One of the most coffee plants in Indonesia is Robusta coffee (Coffea canephora). This study aimed to determine whether Robusta coffee powder could accelerate the wound healing process. This was an experimental study using four rabbits as subjects. Incisions were made on the rabbit backs, right and left, with a length of 5 cm. Wounds on the left backs, the untreated/control group, were only covered with sterile gauze. Wounds on the right backs, the treated group, were applied with robusta coffee powder and covered with sterile gauze. Robusta coffee powder and gauze were replaced two times a day. Wounds were macroscopically observed for 2 weeks. The results showed that at day 7, the wounds were still equally opened, dry, looked not too deep, and there was a crust on each wound surface. The lengths of the treated wounds were shorter than of the control wounds. At day 14, the edges of the treated wounds looked closer, the crusts were still attached to the wound surfaces and were smaller than of the control wounds. Conclusion: Robusta coffee powder (Coffea canephora) could accelerate the healing process of incised wounds on rabbit skin.Keywords: wound healing, wound incision, robusta coffee powder, coffea canephoraAbstrak: Kopi bukan hanya dikenal sebagai makanan dan minuman saja tetapi bisa juga sebagai obat alternatif dalam menangani berbagai jenis luka.

Objective: To study the effect of both laser and ultrasound radiation on bone fracture healing process. Materials and Methods: Nd:YAG laser (1064 nm wavelength, 135 mW power, 16 joules energy) and ultrasound (1 MHz frequency, 50 mW/cm2 power intensity) were used in this work. Fifteen mature, male, albino rats, were divided into three groups and subjected to a partial fracture on the lateral aspect of femur by a sharp blade. The fi rst group of these animals served as control group. The second group was illuminated by the Nd:YAG laser for two minutes; the fi rst dose was given immediately after surgical fracture induction; the other doses were given on days two, three, six and then one dose weekly for the next three weeks while the third group were treated by the addition of the CW ultrasound perpendicular to the laser treatment in the second group. Results: The present study showed that ultrasound increases the penetration of laser power through the tissue. The histological assessments at day 28 after the fracture of fi rst group showed incomplete healing of the bone with disfi guration and disarrangement of Haversian system and the periosteum was not yet well developed. Treatment with laser showed irregularity and lack of Haversian system formation in bone healing of the second group. The laser and ultrasound treated group (third group) expressed a complete healing at the site of fracture with a complete layer of periosteum and a well arranged Haversian system. Conclusion: Combination of laser and ultrasound in therapy can enhance healing process of a fractured bone more than laser therapy alone, as ultrasound increases the depth of laser penetration in tissue.

This article reports the influence of an autologous leukocyte- and platelet-rich plasma (L-PRP) injection as a minimally invasive method on supporting wound healing processes after a mandibular odontogenic cystectomy and double mandibular fracture fixation. 113 patients were enrolled into a control group (received no L-PRP injection) and 102 patients were enrolled into an L-PRP group with an oral mucosa incision. 18 patients after a double mandibular fracture were operated on using 2 external submandibular approaches receiving no fluids in the right site (a control group) and an L-PRP injection in the left incision (L-PRP group). Clinical observations showed that the oral mucosa healed faster in patients treated with L-PRP, in comparison to cases where inductive biomaterial was not added. Pain at the L-PRP injection site was relieved within few hours after an operation in patients with double mandibular fractures. However, there were no differences observed in the progression of the healing process. L-PRP possesses inductive properties that could stimulate healing processes and it seems to be one of the most promising methods in the future for the treatment of soft tissue defects.
