Volume 3, Issue 2 (Autumn – Winter 2010[PERSIAN] 2009)
Abstract
Abstract Background and objectives: A major problem for labs. esp. medico legal centers is drug test false positive and negative results. Using carbon paper, sodium bicarbonate or oral contraceptive pills (OCP) are common among addict people to make the results negative. Therefore, we decided to evaluate the effect of carbon paper, sodium bicarbonate or OCP on morphine urine test. Material and Methods: We performed this pre-experimental study on the urine samples of all people referred to narcotic drug laboratory of Markazi province during May of 2005. Of 2110 urine samples, the Morphine Rapid Test of 208 samples was positive. Then by means of TLC method, we confirmed the presence of morphine metabolites in 150 urine samples. After that, we divided these samples into three equal groups for adding carbon paper, sodium bicarbonate or OCP. Results: The results show that in carbon paper group, 41 cases are positive and nine cases unclear. In sodium bicarbonate group, 45 samples are positive and 5 cases unclear. In estrogen conjugate group, all 50 samples are positive. Conclusion: According to this study, adding carbon paper, sodium bicarbonate or oral contraceptive pills cannot make negative the Morphine Rapid Test result.

Abstract

Abstract Background and Objective: some of predisposing factors for enterococci colonization are hospitalization in ICU, prolonged use of antibiotics and continued bed rest in hospital. In this study antibiotic resistance of enterococcus in hospitalized patients of four hospitals in Tehran were studied. Material and Methods: the Clinical samples were taken from patients admitted to the ICU, from September 2011 to April 2012. Enterococci isolates were confirmed by biochemical tests, and Enterococcus faecalis and Enterococcus species by species-specific ddl genes. The disk diffusion and micro agar dilution susceptibility tests were performed according to Clinical and Laboratory Standards Institute (CLSI). Results: of 41 isolates in ICUs, 22 (5.52%) were E. faecium and 19 (5.47%) were E. faecalis. Most of E. faecium was isolated from urine and E. faecalis from trachea specimens. The rate of resistance to vancomycin, ampicillin, gentamicin, chloramphenicol and nitrofurantoin in E. faecium isolates was more than that of E. faecalis and the rate of resistance to tetracycline, ciprofloxacin and erythromycin was the same in both of them. MIC50 in vancomycin and ampicillin resistant E. faecium isolates was greater than 256 microgram and the MIC50 in gentamicin resistant isolates was more than 1024 microgram. . Conclusion: The presence of multi-resistant E. faecium strains in ICUs can be a serious warning for physicians and patients.

Volume 10, Issue 5 (Sep-Oct-2016 2016)
Abstract

ABSTRACT

        Background and Objective: Scientific evidence reveals that the density of skeletal muscle microcirculations decreases in the patients with chronic heart failure. Therefore, this study aimed to determine the impact of submaximal aerobic exercise training on restoration of fast/slow-twitch muscle fibers microcirculation in rats with myocardial infarction.

         Methods: In this experimental study, 30 male infarcted Wistar rats were randomly divided into three groups of sham (N=10), control (N=10) and exercise (N=10), four weeks after surgery (blockage of anterior descending artery). Daily aerobic exercise included running on a treadmill for 10 weeks (5 times a week) at a speed of 17 m/min within 10 to 50 minutes. The animals were anesthetized and then sacrificed with chloroform, 48 hours after the last training session. The microcirculation density of soleus (SOL) and gastrocnemius (Gw) muscles was evaluated by immunohistochemistry assay.

        Results: Capillary density and capillary to SOL muscle fiber ratio significantly increased in response to exercise training. However, capillary density, capillary to Gw muscle fiber ratio and Gw muscle arteriolar density of Wistar rats with chronic heart failure were not significantly affected by the exercise program. Moreover, arteriolar density of Gw muscle increased significantly after the exercise program.

        Conclusion: The ten-week aerobic exercise might non-uniformly improve the SOL and Gw muscles microcirculation in rats with chronic heart failure by increasing capillary density and capillary to fiber ratio in the SOL muscle and increasing the arteriolar density of the Gw muscle.

Volume 14, Issue 1 (Jan-Feb 2020)
Abstract
Abstract
           Background and Objectives: Liver is one of the vital organs of the human body. Antioxidants have been shown to play important roles in reducing liver injuries. The aim of this study was to examine the effects of gallic acid supplementation and resistance exercise on liver damage biomarkers in male rats intoxicated by steroid anabolic.
           Materials and Methods: Forty-two male Wistar rats were randomly divided into six equal groups: control, sham, steroid anabolic (5 mg/kg), steroid anabolic (5 mg/kg) + gallic acid supplementation (50 mg/kg), steroid anabolic (5 mg/kg) + resistance exercise, and steroid anabolic (5 mg/kg) + gallic acid supplementation (50 mg/kg) + resistance exercise. Except for control and sham groups, all groups received (injection) steroid anabolic at a dose of 5 mg / kg body weight once a week. The resistance exercise protocol was comprised of three weekly exercise sessions by 5 rep/3 set of climbing ladder for eight weeks. Data were analyzed via ANOVA and Tukey's post hoc test at a significance level of P<0.05.
           Results:  The hepatic enzymes (alanine aminotransferase, aspartate aminotransferase and alkaline phosphatase) and bilirubin (total and direct), "In the gallic acid supplementation group (P<0.01, p<0.01, p<0.01, p<0.02, and p<0.05, respectively), resistance training group (p<0.02, p<0.01, p<0.01, p<0.01, and p<0.05, respectively), and the gallic acid supplementation group with resistance exercise (P<0.02, p<0.01, p<0.01, p<0.01, and p<0.01, respectively)"  were significantly reduced compared to the anabolic steroid group.
           Conclusions: Gallic acid supplementation and resistance exercise significantly reduce liver damage biomarkers. However, the simultaneous use of resistance exercise and gallic acid supplementation has no increasing effects on these biomarkers.
           Keywords: Anabolic Agents, gallic acid, Resistance Training.

Effect of Four Weeks Plyometric Training with and without Blood Flow Restriction on Serum Bone Formation and Degeneration Markers in Inactive Girls
Fatemeh Fakhri, Abdolhamid Habibi, Mohsen Ghanbarzadeh, Rohollah Ranjbar,
Volume 14, Issue 3 (May-Jun 2020)
Abstract
Background and Objectives: It has been shown that low intensity physical activity rarely increases bone density or renewal. Therefore, the purpose of this study was to investigate effects of four weeks of plyometric training with and without vascular occlusion on serum levels of bone‌ alkaline phosphatase (BALP) and C-terminal telopeptide of type I collagen (CTX), as markers of bone formation and bone degeneration in inactive girls.
          Methods: This was a semi-experimental study with a pretest-posttest design. The study population consisted 36 inactive female students aged 23.84±1.096 years with a mean body mass index of 22.59±0.52 kg/m2 who were randomly divided into a plyometric training group without blood flow restriction, a plyometric training group with blood flow restriction and a control group. The experimental groups performed four weeks of plyometric training (three sessions per week), while the control group did not perform any exercise. Blood samples were obtained 48 hours before the first training session and 48 hours after the last training session. Measurement of BALP and CTX was carried out using commercial enzyme-linked immunosorbent assay kits. Collected data were analyzed using t-test and one-way analysis of variance. All statistical analyses were performed using SPSS software (version 23) and at significance level of ≤ 0.05.
          Results: The level of BALP was significantly higher in the low intensity exercise with blood flow restriction group compared to the control group (P=0.005) and the low intensity exercise group without blood flow restriction (P=0.003). The BALP/CTX ratio, as marker of bone metabolism, increased significantly following low intensity exercise with blood flow restriction compared with the other groups (P<0.05). However, low intensity exercise without blood flow restriction induced no significant change in the studied indices.
          Conclusion: Plyometric training with blood flow restriction could be as effective as high intensity training for improving bone metabolism and turnover, particularly in inactive individuals.
