Considering the high consumption of and preference for traditional treatments among people and the lack of enough studies on the effectiveness of these treatments, we aimed to review articles on the use of traditional and complementary medicine, focusing on how they affect healing, debridement, and hypertrophic scars. In this study, we conducted the literature search in international databases PubMed, Google Scholar, Ovid, Scopus, Web of Science, and Cochrane Library, as well as Persian databases Scientific Information Database (SID), Magiran, Iranmedex, and IranDoc. Retrieved hits were reviewed by three authors for screening based on inclusion and exclusion criteria, and the screening process is expressed as Preferred Reporting Items for Systematic Reviews and Meta-Analyses framework flow chart. Twenty-two studies were included. The evaluated outcomes were wound healing in 19, pain control in 5, itching in 4, and scar appearance in 2 studies. All of the studies showed equal or improved effects compared to common treatments. Aloe vera , Centella asiatica , and Arnebia euchroma were the most common plants. We revealed that traditional medicine is beneficial in burn wound treatment. The diversity in ingredients that are used in traditional medicine brings up the need for further controlled prospective studies to evaluate the precise superiority of these treatments compared to standard care.

Burn injuries are considered an important public health problem in the world. Burns are considered the fourth most common kind of trauma in the world, after traffic accidents, falls, and interpersonal violence. Various biochemical agents are involved in the burn healing process such as cytokines (such as IL-6 and TNF-α), antioxidants, and liver and kidney damage biomarkers. Cichorium intybus L. and milk thistle extracts showed a wide range of pharmacological activities such as significant antimicrobial effect and antioxidant activity, as well as anti-inflammatory, antidiabetic, antiproliferative, antiprotozoal, and hepatoprotective effect. Also, these two herbs possess blood-cleansing, detoxifying, laxative, and invigorating activities. Some research confirmed that the preparations of the extract are very suitable for the treatment of nonalcoholic fatty liver disease. This is a double-blind randomized controlled clinical trial. Patients with 2nd and 3rd degree burns have been selected to participate in the study according to the inclusion criteria. A total of 60 patients were selected and divided into intervention and control groups (30 patients in each group). Patients in the intervention group received chicory seed syrup 10 cc three times a day and 1 placebo capsule, and those in the control group received placebo syrup (10 cc three times a day) and one Livergol (140 mg of silymarin in each capsule) capsule. Lab data such as liver function tests, albumin, creatinine, BUN, and hemoglobin were checked every 3 days and 1 week after discharge. The treatment lasted for 4 weeks. According to the results of the study, although the average of liver enzymes at the end of the study does not show a significant difference between the two groups, the level of liver enzymes in each group decreased on the 15th day of the study compared to the first day. This trial is registered with IRCT20180609040016N1. [ABSTRACT FROM AUTHOR]

Electrical injuries are an uncommon but very destructive type of burn, with serious complications and disabilities for the victims. This study was conducted due to the importance of understanding the epidemiology of electrical accidents in planning to prevent their occurrence. This is a retrospective cross-sectional study that was performed on patients with electrical burns referred to Shahid Motahari Educational and Medical Center from 2017 to 2018. Patients' information was entered in the researcher-made information registration form, including demographic and accident-related information. In this study, most of the accidents occurred in the workplace with high-voltage electricity. Contact with overhead cables and wires was the most common cause of injury. Excision and graft surgeries were the most common type of surgery. The variables of sex, age, length of hospital stay, and type of job had a significant relationship with the type of voltage (P < .05). The difference between the ratio of men to women and the length of hospitalization in the group of injured with high-voltage electricity was greater and most of these patients were construction workers. The variables of sex, nationality, length of hospital stay, and cause of the accident had a significant relationship with the type of job (P < .05). Construction workers are the main group at risk of electrical damage in Iran. Therefore, it is recommended to conduct more extensive studies in the field of recognizing and implementing practical methods of preventing electrical injuries, especially in high-risk work environments.

Introduction : Apoptosis is one of the most important biological processes, which occurs through the activation of intracellular cell death pathway. Aim : The aim of this study was to determine the pattern of cell death within the early stages of spinal cord injury (SCI) and the evaluation of the changes in Bax protein expression of progressive apoptosis. Material and methods : 48 adult male Sprague Dawley rats were randomly divided into two control and experimental groups. Animals were anesthetized and then the laminectomy procedure was performed in the area of T6–8. On days 1, 7, 14 and 28 after the surgery, one-third of the middle part of their testis tissue were taken for histological and immunohistochemical analysis. Results : The immunohistochemical analysis indicated the presence of TUNEL- positive cells and cells containing the pro-apoptotic protein Bax in testicular sperms in the 1st day after SCI, as well as increased on 28 days. Discussion : 1 day after SCI, the apoptosis occurred in testicular sperm lines as well as the apoptosis can be related to Bax protein expression. Therefore inhibition of caspase activity via caspase cascades-mediated apoptosis may have a protective role in testicular injury during the acute phase of SCI. Conclusions : Our finding suggested that the damage and destruction after SCI can be controlled by therapeutic interventions at the appropriate time before the destructive changes of SCI.

Objective: Poly(ε-caprolactone) (PCL) has considerable mechanical and biological properties that make it a good candidate for tissue engineering applications. PCL alongside proteins and polysaccharides, like gelatin (GEL) and chondroitin sulphate (CS), can be used to fabricate composite scaffolds that provide mechanical and biological requirements for skin tissue engineering scaffolds. The aim of this study was fabricating novel composite nanofibrous scaffold containing various ratios of GEL/CS and PCL using co-electrospinning process. Materials and Methods: In this experimental study, PCL mixed with a GEL/CS blend has limitations in miscibility and the lack of a common solvent. Here, we electrospun PCL and GEL/CS coincide separately on the same drum by using different nozzles to create composite nanofibrous scaffolds with different ratios (2:1, 1:1 and 1:2) of GEL to CSPCL, and we mixed them at the micro/nanoscale. Morphology, porosity, phosphate-buffered saline (PBS) absorption, chemical structure, mechanical property and in vitro bioactivity of the prepared composite scaffolds were analysed. Results: Scanning electron microscopy (SEM) images showed beadless nanofibres at all ratios of GEL to CS-PCL. The composite scaffolds (2:1, 1:1 and 1:2) had increased porosity compared to the PCL nanofibrous scaffolds, in addition to a significant increase in PBS absorption. The mechanical properties of the composite scaffolds were investigated under different conditions. The results demonstrated that all of the composite specimens had better strength when compared with the GEL/CS nanofibres. The increase in PCL ratio led to an increase in tensile strength of the nanofibres. Human dermal fibroblasts (HDF) were cultured on the fabricated composite scaffolds and evaluated by 3-(4,5-dimethylthiazol2-yl)-5-(3 carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium (MTS) analysis and SEM. The results showed the bioactivity of these nanofibres and the potential for these scaffolds to be used for skin tissue engineering applications. Conclusion: The fabricated co-electrospun composite scaffolds had higher porosity and PBS absorption in comparison with the PCL nanofibrous scaffolds, in addition to significant improvements in mechanical properties under wet and dry conditions compared to the GEL/CS scaffold.

Background: Over the past several years, mammals have been successfully cloned by either the splitting of an early stage embryo or nuclear transfer of adult somatic cells (NT) into oocytes. Although it has been 15 years since the generation of the first cloned mammals from somatic cells by NT, the success rate for producing live offspring by this technique is low regardless of the cell type and animal species used. However, these techniques have the potential to be important tools for future research in basic biology. In the present study, we described our experiences in producing successfully cloned mouse using NT method and piezo-actuated micromanipulator. Methods: B6D2F1 mice, 8-12 weeks old, were superovulated with injections of 5 IU of pregnant mare serum gonadotropin and 5 IU of human chorionic gonadotropin administered 48 hr apart. Enucleation and donor nuclei cumulus cell injection were performed with a piezo-actuated micromanipulator after which activation and trichostatin A treatment were used for reconstructed oocytes. Two-cell stage cloned embryos that developed in the mWM medium were transferred into the oviducts of pseudopregnant NMRI mice. Results: Of 367 oocytes collected, 131 (69%) developed into 2-cell stage embryos. Of these, 5 (1%) live pups were successfully delivered. We used NMRI foster mother to raise the pups by lactation. One adult cloned mouse was mated, after which she delivered and raised normal offspring. Conclusion: For mouse cloning, the present study also successfully tested the capability of somatic cell nuclear transfer SCNT using a piezo unit. [ABSTRACT FROM AUTHOR]

Background: In recent years, special attention has been paid to minimally invasive and conservative methods in addition to conventional surgical methods to repair tendon damage. In this regard, the effect of fat injection and graft has been of great interest due to its potential in accelerating tissue repair. We aimed to assess the clinical efficacy of fat injection along with conventional approach in patients with flexor tendon injury., Methods: In this randomized clinical trial, 64 patients were randomly scheduled for tendon repair using the usual modified Kessler four-strand method alone or tendon repair using four-strand method and fat injection on the proximal and distal sides of the repair site in the Hazrat Fatemeh Hospital, Tehran Province, Iran in 2022 (IRCT20221206056723N1). Patients were followed-up for eight weeks regarding the function status of the repaired tendon (using Strickland grading test), range of motion (by physical examination) and flexion and extension gaps (by imaging)., Results: In the eighth weeks after the treatment, the average Strickland score was significantly higher in the group receiving fat injection (P: 0.009 ). In the two pointed times, the mean range of motion was significantly higher and the mean flexion and extension gaps were significantly lower in those who received fat injection. None of the procedural side effects were observed in the fifth and eighth weeks after the treatment., Conclusion: Fat injection along with usual surgical treatment for tendon repair accelerates and improves tendon function and range of motion., Competing Interests: The authors declare that they have no conflicts of interest.

Background: Burns are among the most common causes of injury and result in long-term morbidity, psychological complications, and reduced quality of life. We aimed to evaluate and compare the results of skin grafting versus nonsurgical treatment in patients with deep second-degree burn wounds of the back and posterior trunk., Methods: This is a descriptive-analytical cross-sectional study of patients with trunk and buttock burns admitted to Burn Hospital in Shiraz, Iran from 2017 to 2019. The skin surface with burns and the final repaired tissue was measured. The Vancouver Scar Score (VSS) and pigmentation, vascularity, thickness, and pliability were assessed. VSS, pigmentation, vascularity, thickness and pliability were considered as outcomes., Results: Seventy-five patients met the criteria for participation; thirty-two patients had skin grafts. The mean age was 27.79±20.03 yr and 53 patients (70.7%) were male. Scars were compared based on pigmentation, vascularity, thickness, and pliability, which was also statistically significant ( P <0.001). The mean of VSS was higher in patients with skin graft than those without graft ( P <0.001)., Conclusion: The mean VSS was significantly higher in patients with grade 2 deep burns who received skin grafting than in patients without skin grafting. Due to the lack of donor sites and the need to prioritize skin grafts in burn patients with high total body surface area, it is better to perform skin grafts on the posterior trunk and buttocks in areas with deep grade 2 burns as a last priority and treat this wound with conservative therapy., Competing Interests: The authors declare that there is no conflict of interests.
