RESUMO
BACKGROUND: Wound healing is a critical clinical concept. We aimed to evaluate the effects of topical Mentha piperita essence on cutaneous wound healing. METHODS: This randomized controlled trial was conducted in Tehran University of Medical Sciences, Tehran, Iran in 2019. Square-shaped 1.5×1.5 cm wounds were made on the neck of 60 male Wistar rats in a sterile condition. Samples were randomly divided into a control group and three experimental groups. Group A treated with M. piperita essence and Vaseline. The second group received the M. piperita essence, and the third group received Vaseline. Histological specimens were obtained in 4th, 7th, and 14th days and were explored for fibroblasts, epithelial cells, inflammatory cells, and vessels. RT-PCR was performed for molecular and gene expression evaluation of TGF-ß. RESULTS: The M. piperita essence increases TGF-ß gene expression as an important factor in wound healing. After 14 d, group A, who received M. piperita and Vaseline, had 99.73% of wound healing with the mean wound size of 0.006 cm2 while wound healing in the control group was only 52%. Samples treated with M. piperita have 74.58% wound healing following by group treated with Vaseline, which was 67.02% (P<0.05), respectively. CONCLUSION: The application of the M. piperita essence for wound healing accelerates the process and improves outcomes.
RESUMO
OBJECTIVE: The WHO estimates the global incidence of death by drowning to be about 300 000 cases per year. The objective of this study was to estimate the trend in mortality due to drowning in all provinces of Iran in all age groups and both genders from 1990 to 2015. STUDY DESIGN: The National and Subnational Burden of Diseases (NASBOD) project is a comprehensive project in Iran. It is based on the Global Burden of Disease study and includes novel methods to estimate the burden of diseases in Iran. METHODS: This study used the results of the mortality rate due to drowning as part of NASBOD and investigated the causes behind the mortality rates. The data set recorded mortality rates by 19 age groups and two genders with the corresponding subnational pattern during the time period from 1990 to 2015. RESULTS: The drowning mortality rate decreased in Iran from 1990 to 2015. From 1990 to 2015, the annual percentage change for males and females was -5.28% and -10.73%, respectively. There were 56 184 male and 21 589 female fatalities during the study period. The highest number of deaths was seen in 1993 with 4459, and the lowest number of fatalities was observed in 2015 with 903 deaths. CONCLUSION: Our data showed a decline in drowning mortality in Iran from 1990 to 2015, but the rates and declines varied by province. Our findings are of great importance to health officials and authorities in order to further reduce the burden of drowning.
