The effect of endurance training and taxol consumption on cyclooxygenase-2 and prostaglandin E2 levels in the liver tissue of mice with cervical cancer

Background: Herbs have a strong anti-cancer effect. Also, exercise is one of several lifestyle factors known to lower the risk of developing cancer. The aim of this study was to investigate the effect of endurance training and taxol on cyclooxygenase-2 and prostaglandin E2 in the liver tissue of mice with cervical cancer. Materials and Methods: In this experimental study, 35 female C57 mice were randomly divided into 5 groups (n=7 in each group): control (healthy), control (cancer), complement (cancer), training-supplementary (cancer) and training (cancer). The implantation of cancerous tumors was performed under the skin of the upper pelvis. The training group completed the endurance training protocol, which included 3 sessions per week, 50 minutes per session, at a speed of 14-18 m/s for six weeks. A dose of 60 mg/kg/day of pure taxol was injected intra peritoneally. The dependent variables of this study were measured 24 hours after the last training session by ELISA. Results: The results showed that the use of taxol and endurance training reduced the levels of cyclooxygenase-2 and prostaglandin E2 in the liver tissues of C57 mice with cervical cancer. Conclusion: Induction of the cancerous tissue in mice with cervical cancer increases the levels of cyclooxygenase-2 and prostaglandin E2 and endurance training along with taxol may reduce these levels

The stinging Apidae and Vespidae (Hymenoptera: Apocrita) in Iranian islands, Qeshm, Abu–Musa, Great Tunb and Lesser Tunb on the Persian Gulf

Objective: To study the stinging flying Hymenoptera (Apidae and Vespidae) fauna in four Iranian Islands, Qeshm, Greater Tunb, Lesser Tunb and Abu-Musa on the Persian Gulf. Methods: The flies were captured by used of Malaise trap, fly trap, bottle trap and insect net-hashing from March 2011 to July 2012. Results: In this study, 11 species of stinging Hymenoptera were reported for the first time in Persian Gulf region. Conclusions: Some of this species such as Vespa orientalis and Polistes olivaceus are more common in the Persian Gulf islands and can cause clinical problem to islands resident and travelers

The effect of environmental factors on growth characteristics, seed germination and essential oils of Ziziphora clinopodioides

In this study, the relationship between altitude, climate and soil characteristics as important and effective factors on the growth characteristics, seed germination and essential oils of Ziziphora clinopodioides were examined. Three habitats of this species with different altitudes were selected in Alborz and Mazandaran provinces. Growth characteristics of Z. clinopodioides bushes in 45 plots located at the three habitats were recorded. Seed of this species collected from three habitats and their viability was determined. Three soil samples were taken from each habitat and some physical and chemical characteristics were measured. Analysis variance results of data showed that there is a significant difference among the three habitats from the viewpoint of growth characteristics, soil features and common combinations of essential oils. The highest seed viability was obtained for Rineh habitat with chilling and scratching seed coat. The most important environmental factors affecting the vegetative characteristics and essential combinations was determined using principal component analysis. The results showed that annual temperature, absolute minimum temperature, maximum temperature of the warmest month, number of frost days, altitude, electrical conductivity, moisture saturation, organic matter and soil texture had the greatest impact on these properties

Seroprevalence of anti-helicobacter pylori antibodies in hepatitis B and C patients with cirrhosis: a case-control study

<strong>BACKGROUND</strong>: Cirrhosis is terminal stage of many chronic liver diseases like hepatitis C and hepatitis B. In some studies the role of helicobacter pylori has been demonstrated in progress of cirrhosis and its complications, but none of the previous studies has investigated the role of socioeconomic conditions of patients in childhood period in this issue.<br /> <strong>METHODS</strong>: In a case-control study, we examined 100 cirrhotic patients due to hepatitis (49 hepatitis B and 51 hepatitis C patients) and 101 socioeconomically matched healthy controls presenting to Taleghani Hospital for IgG antibody to helicobacter pylori.<br /> <strong>RESULTS</strong>: IgG antibody to helicobacter pylori was present in 73% of cirrhotic patients and 52% of control group (P<0.003). Odds ratio for the presence of IgG antibody to helicobacter pylori in cirrhotic men comparing with healthy men was 3.2 (95%CI: 1.4-7.4).<br /> <strong>CONCLUSIONS</strong>: The relative frequency of IgG antibody to helicobacter pylori found to be higher in cirrhotic patients than in controls with regard to socioeconomic condition in childhood.<br /> <strong>KEY WORDS</strong>: Cirrhosis, hepatitis C, hepatitis B, helicobacter pylori, liver disease
