In most southern provinces of Iran, Soil Salinity is a growing problem particularly in the irrigated agricultural areas and has been found to reduce crop yields. In order to investigate the role of pod removal in seed germination, seedling growth and antioxidant enzymes activity in annual medics (Medicago scutella L.) under salinity stress conditions, a factorial experiment was conducted at Col...

The incorporation of copper species is synthesized  in a silica matrix by the sol-gel method. We have doped copper ions and copper particles using two different copper sources: Cu(NO3)2.3H2O and copper particles chemically synthesized. We can prepare the particles of copper metallic, cuprous and cupric oxide and  compare the synthesis and characterization copper species on the silica matrix.  O...

we studied cu concentration on part of aras riparian vegetation. cu was selected as an index metal due to polluting the aras river through agarak copper mines drainage. results of cu concentration in indicator plant have been examined using spss16. considering the situation of the copper mines as well as the habitat of the indicator plant, two stations before and after the exit of the industria...

background: the aim of this study was to evaluate copper status in women with preeclampsia. materials and methods: sixty preeclamptic, sixty normotensive pregnant and sixty healthy nonpregnant women were enrolled in a cross sectional study. the 24-hour urine copper was compared among the women. results: there was significant difference in the copper concentration of 24-hour urine among the thre...

in this study we investigated histopathological changes of mice ovarian tissues following long-term administration of copper sulfate and induction of chronic copper poisoning. the study comprised of three different groups of twenty one mice as follows: the first group (group 100) which treated by gavage with copper sulfate at a dose of 100 mg kg-1 for 5 weeks. the second group (group 200), whic...

background: the trace element copper has been identified as a highly toxic element for sperm. it is known to affect sperm motility in humans and experimental implantation of copper in the epididymis vas deferens and scrotum of mammals has been demonstrated to affect fertility detrimentally. objective: sperm concentration motility vitality and morphology are parameters used to evaluate potential...

In order to measure serum copper concentration, 163 adult males working at different units of copper plant from a total population of 671, were selected by simple random sampling. Eighty three subjects working at melting foundry, 49 in extrugen- rolling and 31 at administrative service untils. Eighty four adult male natives of Kerman and it's suburbs were randomly choosen as control group, seru...

background: one of the most critical problems in the field of water and food pollution is the heavy metal pollution. agricultural products are exposed to this type of contamination through wastewater; industrial activity and population pollutions are also in its area. since the plant in the affected areas can directly enter heavy metals into the food chain, so, it is important to check their le...

objectives: the percentage of vowel correct (pvc) is one of the indices in the development of articulation and phonological skills in children that can be measured with speech samples that could be extracted from the single word or connected speech tests. the aim of this study is to introduce the pvc scale in persian speaking children and investigate its validity and reliability. methods: this ...
