This study was done to determine the effect of hydroalcoholic extract of Ferula persica resin on induced rheumatoid arthritis by Freund's complete adjuvant in rat.
Methods: In this experimental study, 36 male Wistar rats (200-250 g) and 8 weeks old were randomly allocated in 6 groups including normal group, positive control, negative control, and groups treated with the hydroalcoholic extract of persica resin with 25, 50 and 75 mg/kg/bw doses. The resin of persica was extracted by Maceration method. On the first day, inflammation was induced with injection of 0.2 ml of Freund's complete adjuvant into the right knee joint of rats and from the fifteenth day hydroalcoholic extract was injected intraperitoneally and daily for 15 days. On the 30^th day, blood samples were taken from hearts for rheumatoid factor measurement. Histological slides were prepared from knee joint.
Results: The level of RF in the three treatment groups was significantly reduced compared to the negative control group (p<0.05). Destruction of cartilage were observed in treated group with dose of 25 mg/kg/bw in comparision with positive control group, treated group with 50 and 75 mg/kg/bw doses. Also in the negative control group, synovial hyperplasia, pannus and the destruction of cartilage were observed.
Conclusion: It seems that hydroalcoholic extract of Ferula persica resin can causes dose dependent reduction of inflammation and destruction of cartilage result from induced rheumatoid arthritis in the rats.

Background and Objective: Obesity by releasing inflammation factors such as Interleukin-6 (IL-6) cause atherosclerosis and cardiovascular diseases. Also, L-carnitine reduces inflammatory factor such as IL-6. The study was done to determine the effect of eight week endurance training with L-carnitine supplementation on IL-6, nitric oxide (NO), blood pressure, and body composition in young obese women.
Methods: In this clinical trial study, 40 volunteer young obese women (age: 23.3±2.3 yrs. and BMI: 31.1±1.4 kg/m²) randomly assigned in the endurance training with L-carnitine (ETL; n=10), endurance training with placebo (ETP; n=10), L-carnitine supplementation (LCS; n=10) and control (Con; n=10). The training protocol consisted of endurance training with gradually increasing of duration and intensity (25-min at 50% HR max and increased to 45-min at 70% HR max), three session a week for 8 weeks. The supplement groups consumed 3gr of L-carnitine daily, while the placebo group ingested the same amount of maltodextrin. Blood pressure and blood samples were obtained before and 36 hours after training protocol, and serum levels of IL-6 and NO were measured by ELISA method.
Results: IL-6, weight, fat mass and fatty percent was significantly reduced in ETL and ETP groups compared to control and LCS groups (P<0.05), and this reduction was lower in the ELT than ETP group (P<0.05). Also, NO was significantly increased in the ELT and ETP groups compared to the LCS and controls (P<0.05).
Conclusion: Although the implementation of endurance training with and without L-carnitine for 8 weeks caused to decrease of IL-6, increase of NO and improved body composition, but the effect of endurance training with L-carnitine on decreasing of IL-6, weight and fat mass was significantly better.

Background and Objective: Stroke and cerebral ischemia are the second leading causes of death in the world. Currently, there are limited therapeutic interventions for patients with ischemia / reperfusion. This study was performed to determine the protective effect of aerobic exercise and adenosine on changes in inflammation mediators after transient ischemia of common carotid arteries in male Wistar rats.
Methods: In this experimental study, fifty male Wistar rats were randomly allocated into to 5 groups: control, cerebral ischemic control, aerobic exercise + cerebral ischemia, adenosine + cerebral ischemia and aerobic exercise + adenosine + cerebral ischemia. Ischemia was performed by blocking the common carotid artery for 45 minutes after a period of exercise and injection of adenosine. Neuronal structure was examined by Nissel tissue staining. The expression of NGF and Glutamate genes were measured in CA1 region of hippocampal tissue samples.
Results: Cell death was increased in neurons in the CA1 region of the hippocampus in the ischemia / reperfusion group, While a significant reduction in cell death in the adenosine + ischemia / reperfusion and aerobic exercise + ischemia /reperfusion groups was due to adenosine administration and aerobic exercise (P<0.05). NGF and glutamate gene expression in the adenosine + ischemia/reperfusion and adenosine + aerobic exersice + ischemia/reperfusion groups significantly increased and reduced compared to the ischemia/reperfusion control, respectively (P<0.05).
Conclusion: Co-administration of adenosine combined with aerobic exercise increase the protective effect of aerobic exercise on improving the neuronal damage after ischemic / reperfusion.

Sports activities are hindered by the lack of clean air in large and industrialized cities, and the countless benefits of exercise are not considered. With the search of the literature, 89094 articles related to air pollution that have been published in SID, PubMed, and Web of Science until December 2021 were found. Ultimately, 80 articles were extracted after selecting the articles and narrowing the search to exercise inflammation and lung tissue. After removing out-of-date articles (not published between 2000 and 2021) and those without full text, 65 articles were included in the review. Based on the review, exposure to air pollution is associated with increased inflammation and decreased cellular immune function, which is characterized by the activation of toll-like receptors and downstream signaling pathways. Regular exercise improves the inflammatory status in different pulmonary diseases. People who exercise in polluted environments are at increased risk of respiratory and cardiovascular diseases due to the elevated amount of pollutants delivered to the lungs. However, studies did not take into account the potential anti-inflammatory effects of exercise training, which could inhibit the pro-inflammatory events induced by air pollution. It seems that regular exercise modifies pulmonary inflammatory responses and body mass and in part decreases the risk of pulmonary diseases.
