[Evaluation of short-term survival of patients with acute myocardial infarction and the differences between the sexes in Isfahan and Najaf Abad between [1378 - 1387]]

The purpose of this study is detecting short-term survival of all hospitalized patients with acute myocardial infarction in Isfahan and Najaf Abad based on sex. The data of all patients who were hospitalized with acute myocardial infarction between 1378 to 1387 in Isfahan and Najaf Abad were collected by trained nurses of the surveillance department in a research center. Using these information and Cox proportional hazard method, Kaplan-Meier method and log Rank test, the survival by sex in different subgroups of patients, was determined and compared between two sexes. Short-term 28 days survival following the occurrence of acute myocardial infarction is 90.9%. A significant difference was seen between overall women and men survival [Respectively, 86.7% vs. 92.5% p<0.001]. It decreases significantly with increasing age and increases with thrombolytic use. The survival rate of acute myocardial infarction in Iranian women is less than men. Physicians should pay more attention to the treatment and care of patients at higher risk of mortality, especially women and older patients

Effect of opium dependency on burn healing in a rat model: an experimental study

This study aimed to investigate the effect of opium dependency on the healing of third-degree burns in rats. Twenty-four rats were randomly divided to experimental and control groups. In the experimental group, opium was added to the drinking water for 21 days at increasing concentrations. The control group did not receive opium. To prove dependency on opium in the rats, nal-oxone was injected intraperitoneally. Full-thickness burn wounds were inflicted by applying an iron cuboid preheated to 94°C to the flank of all rats for 20 s. On day 14 after burn injury, full-thickness biopsies were taken. Blind histopatho-logic evaluation was performed to assess length and thickness of the re-epithelialization area, number of neutrophils, fibroblasts, mononuclear cells and new vessels, and percentage of tissue in repair [neutrophilic exudate, and granulation and fibrous tissue]. Findings were analyzed using SPSS software. The wound surface area was 95 +/- 43.35 mm[2] in the control group and 120.4 +/- 50.12 mm in the experimental group [p = 0.224]. The [2] findings show that opium de-pendency has no significant effect on the healing of burn wounds in rats except for the number of monocytes on day 14 [p < 0.05]. Morphine dependency does not seem to be as effective on third-degree burn healing
