RESUMEN
Heavy metals are among the most important environmental pollutants which accumulate in various organs and are associated with several toxic effects. This study was performed to determine the status of heavy metals in river buffaloes in Khuzestan province, Iran, and its relationship with hematologic and serum biochemical parameters. A total of 103 apparently healthy buffaloes were sampled from the region. The concentration of heavy metals, including lead (Pb), mercury (Hg), and cadmium (Cd), was determined in serum samples by atomic spectroscopy. In addition, complete blood counts and serum biochemical profiles were assessed. The serum concentration of Cd, Pb, and Hg in the sampled buffaloes, as mean±standard error, were 0.55±0.01, 6.51±0.10, and 6.28±0.09 µg/l, respectively, which are within the permissible serum levels in the livestock. Serum Cd and Hg levels showed no significant relationship with hematologic or biochemical analytes. However, there were significant negative correlations between Pb levels and phosphorus, magnesium, sodium, as well as potassium concentrations, while serum iron was positively correlated with lead (P<0.05). In addition, there was a significant positive correlation between Hg level and serum aspartate aminotransferase activity (P<0.05). Despite the fact that river buffaloes in Khuzestan spend a long time daily in the Karun River with high industrial pollution, no serum evidence of heavy metal toxicity was found in these animals. It can be suggested that river buffaloes in Khuzestan seem to be resistant to the environmental pollution caused by heavy metals. However, further studies are required to confirm this issue and identify its possible explanations.

BACKGROUND: Quality of life in post-menopausal women and menopausal symptoms are closely related concepts. Influence health education policy in order to promote health and adopt a menopause lifestyle requires alternative strategies, including health training programs with community - based interventions. The current study aims to survey the effects of support groups on quality of life of post-menopausal women. METHODS: A blind field trial (2010) was conducted at Saadatmandii Clinical Center (Robat Karim, Iran). 110 women were selected randomly divided into test and control groups (consisting of 55 ones). Menopause specific quality of life questionnaire (MENQOL) was used for evaluation of life quality before and three months after intervention; there was no intervention in the control group. Data were analyzed by using SPSS/16. Qualitative variables were analyzed using chi-square tests and quantitative variables were analyzed using Mann-Whitney and Wilcoxon test, paired T-test and independent t-test. RESULTS: There was significant difference between vasomotor, psychosocial, physical, sexual aspects and life quality of this group pf women (P<0.001). There was no statistically significant difference in the quality of life of women in control group. CONCLUSION: According to the results method of support group can lead to improved quality of life for post-menopausal ones and it can be appropriate healthcare policy to promote health and improve life quality of this group of women.
