Intensity Of Exercise

Background: The creatine phosphokinase-MB (CPK-MB) isoenzyme level is useful in determining the myocardial infarction (MI) extent and time. Evidence indicates the possible effect of exercise training on reducing the amount of CPK-MB, but the proper intensity of exercise is still unclear. Objectives: In this study the effect of intensity of exercise training on creatinine kinas after a myocardial infarction in plasma levels of male Wistar rats was comparing. Methods: Thirty two male Wistar rats at 10 weeks of age were divided in to four groups [low (N = 8), moderate (N = 8), and high (N = 8) intensity interval training and a control (N = 8) group (no exercise)]. Six weeks later, rats became MI patients through surgery. CPK-MB plasma levels were investigated before training, immediately after training for six weeks as well as 12 hours after MI. The data were analyzed by ANOVA with repeated measure and Tukey (α ≥ 0.05). Results: The results showed that changes in CK enzyme at 12 hours after MI in LIIT (113.88 ± 19.25), MIIT (135.88 ± 35.58) and HIIT (105.75 ± 19.05) were statistically significant compared to the control group (124.62 ± 23.41) only in 12 hours after MI and this reduction in the low-intensity interval training group was significant than the other two groups (P = 0.0001). Conclusions: In this study, six weeks of interval training with each intensity was likely to make cardiac cells resistant to necrosis resulting in low levels of the CPK-MB enzyme compared to the control group after the myocardial infarction event.

Objective: This study aims to evaluate the cardioprotective effect of fisetin on change in the activities of lysosomal enzymes in isoproterenol (ISO)- induced myocardial infarction (MI) in male albino Wistar rats. Methods: Rats were orally pretreated with fisetin (30 mg/kg body weight) daily for 30 days. After the pretreatment period, ISO (100 mg/kg body weight) was subcutaneously administered to rats at intervals of 24 h for 2 consecutive days. Results: The activities of β-glucuronidase, β-N-acetylglucosaminidase, β-galactosidase, cathepsin-B, and cathepsin-D were significantly (*p<0.05) increased in serum and the heart of ISO-induced rats. Pre-treatment with fisetin daily for 30 days to ISO-induced rats significantly prevented these activities and restored their activities to near normal. Oral treatment with fisetin (30 mg/kg body weight) to normal control rats did not show any significant effect. Conclusion: We have concluded that fisetin protects the β-glucuronidase, β-N-acetylglucosaminidase, β-galactosidase, cathepsin-B, and cathepsin-D against ISO-induced MI. The observed effects might be due to the free radical-scavenging and membrane-stabilizing effect of fisetin.

Progressive Renal Insufficiency

Under experimental conditions severe reduction of renal mass results in the hyperfiltration of the remaining nephrons leading to a progressive renal insufficiency. Similar changes are observed in patients with various renal disorders associated with a loss of the functioning nephrons. The progression of renal damage is accelerated by high protein and phosphate intake, and may be modified by the dietary restrictions.We studied 50 five-sixth nephrectarrized male Wistar rats on a standard diet (Rodent Laboratory Chow 5001 Ralston Purina Co., Richmond, Indiana; containing 23.4% protein) over a 20 week period.

Abstract. Physical exercise increases free radicals production; antioxidant supplementation may improve the muscle fiber’s ability to scavenge ROS and protect muscles against exercise-induced oxidative damage. This study was designed to examine the effects of all-trans resveratrol supplementation as an antioxidant to mediate anti-oxidation and lipid per-oxidation responses to exercise in male Wistar rats. Sixty-four male Wistar rats were randomly divided into four equal number (n = 16) including training + supplement (TS), training (T), supplement (S) and control (C) group. The rats in TS and S groups received a dose of 10 mg/kg resveratrol per day via gavage. The training groups ran on a rodent treadmill 5 times per week at the speed of 10 m/min for 10 min; the speed gradually increased to 30 m/min for 60 minutes at the end of 12th week. The acute phase of exercise protocol included a speed of 25 m/min set to an inclination of 10° to the exhaustion point. Superoxide dismutase (SOD), glutathione peroxidase (GPx), catalase (CAT) activity, non-enzymatic antioxidants bilirubin, uric acid, lipid peroxidation levels (MDA) and the total antioxidant capacity (TAC) were measured after the exercise termination. The data were analyzed by using one-way ANOVA. The result showed that endurance training caused a significant increase in MDA level [4.5 ± 0.75 (C group) vs. 5.9 ± 0.41 nmol/l (T group)] whereas it decreased the total antioxidant capacity [8.5 ± 1.35 (C group) vs. 7.1 ± 0.55 mmol/l (T group)] (p = 0.001). In addition, GPx and CAT decreased but not significantly (p > 0.05). The training and t-resveratrol supplementation had no significant effect on the acute response of all variables except MDA [4.3 ± 1.4 (C group) vs. 4.0 ± 0.90 nmol/l (TS group)] (p = 0.001) and TAC [8.5 ± 0.90 (C group) vs. 6.6 ± 0.80 mmol/l (TS group)] (p = 0.004). It was concluded that resveratrol supplementation may prevent exercise-induced oxidative stress by preventing lipid peroxidation.

<p>Liver is an organ with complex metabolism. When the liver is inflamed, cellular immunity will defend against inflammatory agents by stimulating immune cells to produce reactive oxygen species (ROS). Excessive ROS accumulation cause oxydative stress with increased  liver malondialdehyde (MDA) level. Some researches showed that purple sweet potato contain flavonoids (anthocyanins) that functioned as antioxydants. This study aimed to show the prophylactic effect of purple sweet potato extract to the liver MDA level of male Wistar rats induced by carrageenan.</p><p>This study used post-only control group method using 18 male Wistar rats divided into 3 groups: group of rats without treatment, group of rats induced by 0,1 ml of 1% carrageenan by intraplantar injection on day-8, and group of rats given with 872 mg/kgBW of purple sweet potato extract for 7 days and induced by 0,1 ml of 1% carrageenan. In the end of the study, the liver MDA levels were measured by Thio-Barbituric Acid method on each groups.</p><p>The results of One-Way ANOVA test showed there was no significant difference (p = 0,290) between group of rats without treatment (<em>x̅</em>= 207,50) and group of rats induced by carrageenan (<em>x̅</em>=233,17). Then, there is no significant difference (p = 0.978) between group of rats induced by carrageenan and group of rats given with prophylactic purple sweet potato extract and induced by carrageenan (<em>x̅</em>= 232,50).</p><p>The conclusion of this study is giving intraplantar injection of carrageenan can increase liver MDA level insignificantly and giving prophylactic purple sweet potato extract has an effect to decrease the liver MDA level of rats induced by carragenan insignificantly because it contains anthocyanins as antioxidants.</p><p> </p><strong>Keywords: </strong>Liver, <em>Ipomoea batatas</em> L., Malondialdehyde, Anthocyanins
