ABSTRACT
Background: Regarding the current trend of turning attention towards the clinical application of herbal drugs in the healing of burn wounds, the present study was designed to evaluate the effect of Arnebia leaf on the healing process of second degree burn wounds in rat
Materials and Methods: After the production of a second degree burn covering 10% of total body surface area on 40 adult albino rats [weighing 220+/-30 g.] animals were divided into 4 groups: treatment group using herbs containing Arnebia leaf; treatment group using herbs containing no Arnebia leaf; silver sulphadiazine [SSD] treatment group and normal saline treated group. All groups were treated and controlled once a day up to the 30[th] day that they decapitated for histological study of healing process [e.g. epidermal area density, blood vessel density and number in the area]. Data analyses were done using one-way ANOVA and post-hoc Tukey tests
Results: Morphometric studies showed that herbal treatment group containing Arnebia leaf compared to herbal treatment group with no Arnebia leaf and SSD group for epidermal area density had a significant lower [P<0.0001 and P<0.002, respectively] and compared to no Arnebia leaf group a significane higher number and density of blood vessels [P<0.001 and P=0.004, respectively]
Conclusion: This study shows that Arnebia leaf did not have any effect on healing of second degree burn wounds in rat's. More study were recommended for evaluating the effects of other parts of the plant on burn healing
ABSTRACT
Continuing education is one of priorities of newly graduates from medicine and selection of a proper residency program is a major problem for most of them. This study examined various motives and reasons for inclination of graduates from medicine to continue education in a special residency program and become specialized. This is a cross-sectional study. A questionnaire was developed after holding a focus group.Validity and reliability of results using the questionnaire were assessed. Then the questionnaires were sent and received by free mart through universities. Chi-Suquare, One way ANOVA and Post Hoc test, Bonferroni type, was used to study relationships Between different variables. 1052 residents participated in the study. Response rate was 27%. The first and second most important information sources used to choose a residency program were experts and related books [like ketab-e-sabz] respectively. 303 [28.8%] of participants a greed that they need information a bout future of their specialties of choice. The most important factors influencing selection of a program, ordered according to their importance, were tangibility of the impacts of patients treatment, types of diseases, variety in a program, previous academic extensive job opportunities. This study showed there are various reasons to select a residency program. However information and awareness of resident a bout the program they chosed was not sufficient. Therefore informing residents before choosing programs seems to be necessary
