[ effect of active learning method on stability of information and satisfaction of physiopathology students in Yazd university of medical sciences]

Active Learning Method [ALM] is a model in which students are active in the class. This aim of this study is to compare stability of information and satisfaction of students in classic method of lecture and active learning method. This descriptive cross-sectional study was performed on 48 medical students [29 females and 19 males] selected through census sampling method and spending their physiopathology courses in Yazd Shahid Sadoughi University of Medical Sciences. Some sessions from the courses of "respiratory, digestive, and urinary diseases" were selected. Two forms for assessing students' satisfaction were used as pretest and post-test. The stability of information was assessed by 8 essay questions one month after teaching. SPSS software was used for data analysis using descriptive statistics, Mann Whitney and McNemar tests. Fifty six percent of students were generally satisfied with the project implementation. The median for stability assessment exam in classes held using ALM was 5 while it was 3.42 for classes using lecture method which had a significant difference [P=0.00]. Active learning method increases information stability in students' mind after the teaching session

[Comparing effect of vitamin E and allopurinol in diabetic patients with renal dysfunction undergoing coronary bypass surgery]

Acute renal failure is a common complication of cardiac surgery and oxidants and diabetes play an important role in renal injury in this condition. In this study, we aimed to assess whether vitamin E as a supplemental antioxidant and allopurinol as an oxygen radical antagonist could prevent renal dysfunction after coronary artery bypass graft [CABG] surgery. Eighty diabetic patients with GFR less than 60 ml/min undergoing CABG surgery were randomized into two groups: treated with vitamin E and allopurinol [group A: n=40] and without treated [group B: n=40]. Diabetic patients were detected. Group A, drugs 3 to 5 days before surgery. Serum creatinine, potassium, creatinine clearance and urine output were measured preoperatively and daily until day 5 after surgery. The patients consisted of 41 males and 39 females with a mean age of 63 +/- 9 years. The mean serum creatinine and creatinine clearance were 1.3 +/- 0.5 mg/dl [0.8 +/- 3 mg/dl] and 48 +/- 10 ml/min [22-68 ml/min], respectively. There were no differences in baseline variables such as age, body mass index, sex, hypertension, diabetes, duration of operation and aorta cross clump, serum creatinine and potassium, and creatinine clearance between the groups. When comparing two groups, there were no significant differences in mean of variables before and after operation such as serum creatinine [1.2 +/- 0.4 vs. 1.2 +/- 0.3 mg/dl, p=0.4], serum potassium [4.3 +/- 0.3 vs. 4.4 +/- 0.3 meq/l, p=0.7]. Length of intensive care unite stay in control group was more than treated group [3.8 +/- 1.2 vs. 2.8 +/- 0.5 day, p=0.00]. Prophylactic treatment with vitamin E and allopurinol have no Reno protective effect in these patients but these two drugs can decrease hospitalization in ICU with intervention by two drugs
