ABSTRACT
BACKGROUND: Surfactant protein D (SP-D) is a member of the collectin family and is an important component of the pulmonary innate host defense. To find the relationship between exercise training and SP-D in diabetes, we examined the possible effects of a 10-week endurance exercise-training program on serum levels of SP-D, leptin, lipid profile and insulin resistance in obese women with type-2 diabetes mellitus (T2DM). METHODS: Twenty-two obese women with T2DM were randomly assigned to either exercise training (ET) or control (C) group. A subject dropped from ET group due to personal reasons and 1 subject dropped from C group due to commitment to experiments conditions. A total of twenty obese women with T2DM were randomly assigned into endurance exercise training (ET = 10) and control (C = 10) groups. The training group underwent a progressive endurance-training program for 10 weeks (running on a treadmill for 30-55 min/day at 50-75% heart rate reserve) and the control group did not participate in any exercise program. Venous blood samples were collected from both groups before and 72 h after the last session of exercise training for analysis of serum SP-D, leptin, lipid profile, glucose and insulin. Data were analyzed using 2 (group: control, endurance training) × 2 (time: pre, post) ANOVA with repeated measures on the second factor. Absolute changes from rest (∆ baseline) values were calculated according to the following formula: ((measure-baseline)·baseline-1)·100. Percent change between groups was analyzed using independent t-tests (p < 0.05). All analyses were completed using SPSS 19. RESULTS: The serum SP-D levels were decreased after exercise training in ET (∆ = - 78.78 ± 17.14%, p = 0.001) when compare to C (∆ = 9.41 ± 4.75%). Obese diabetic women in the ET group showed significantly lower serum leptin levels (8053.27 ± 878.7 pg/ml, ∆ = - 26.97 ± 16.41%) when compared with women in the control group (9885.5 ± 696 pg/ml, ∆ = 7.02 ± 3.46%, p = 0.003). Fasting glucose was favorably and significantly affected by the intervention (ET ∆ = - 17.01 ± 12.74%, Control ∆ = 15.47 ± 7.32%, p = 0.011). VO2max as an index of aerobic fitness was significantly increased after 10-weeks of endurance exercise training (ET ∆ = 19.29 ± 6.18%). CONCLUSIONS: Endurance exercise training with improvement in aerobic fitness induced a significant reduction of serum SP-D levels in obese women with T2DM.
ABSTRACT
BACKGROUND: Fibroma, the most common benign pelvic tumor in women, affects 25 to 30% of women of reproductive age. Primary treatment for patients with symptomatic or large fibroma is surgery. OBJECTIVE: The purpose of this study was to investigate the effect of a single rectal dose of Misoprostol on bleeding during abdominal hysterectomy. METHODS: This double blind randomized clinical trial was conducted with 80 candidates for abdominal hysterectomy, due to uterine myoma, in the Shahid Sadoughi hospital of Yazd in 2012. The aim of this study was to assess the effect of single rectal dose of Misoprostol on peri-operational abdominal hysterectomy bleeding. Following administration of 400 micrograms of Misoprostol in the case group (n=40), predetermined criteria were compared with control group (n=40). RESULTS: Volume of bleeding during the operation was significantly lower in cases where Misoprostol was used. (268.71 ± 156.85 vs. 350.38 ± 152.61 cc in the case and control groups, respectively). Our findings also showed that Hemoglobin (Hb) levels before, 8, and 30 hours following the operation differed significantly (p=0.001), but these changes were similar in both groups. Pre-operative Hb levels were 11.90 ± 1.7 and 11.90 ± 2.0 in the case and control groups, respectively. CONCLUSION: A single rectal dose of Misoprostol has positive effect on reducing peri-operational bleeding in women undergoing abdominal hysterectomy due to symptomatic leiomyoma.
