the aim of this study was to evaluate an enzyme - linked immunosorbent assay (elisa) for the detection of anti - helicobacter pylori (h. pylori) specific igg antibodies in specimens of oral fluid. all subjects over the age 18 years undergoing endoscopy for any reason were asked to participate in the study. two groups of 44 patients in each were selected as hp+ and hp-. at the same time, 5 milli...

mucopolysaccharidoses are a group of rare mostly autosomal recessive metabolic and genetic disorders. because of the high rate of consanguinity, they are not uncommon in our population. clinical diagnosis is not difficult for experienced physicians, but it is not enough for treatment and prevention measures in the future pregnancies. so, it is necessary to detect the type of mps by measurement ...

The number of patients with end-stage renal disease is growing rapidly in Asia. Patients with end stage renal disease failure (ESRD) undergoing long term hemodialysis (HD) are at risk for high oxidative stress. There is paucity of information with regard to oxidative stress during HD. Therefore, the aim of the present study was to evaluate catalase enzyme activity in erythrocytes and the total ...

materials and methods in this descriptive study, 2988 stool samples of patients with acute gastroenteritis were collected from children’s hospitals of 5 main cities of iran. the samples were sent in frozen condition to pediatric infection research center in tehran and stored at -70°c. elisa test was performed for detection of rotavirus antigens. the mean age of study population was 1 to 5 years...

The present study was aimed to enzymatic antioxidants (superoxide dismutase, catalase, polyphenol oxidase), nonenzymatic (saponin, flavonoids, ascorbic acid and tannin), anti-oxidant ability assays (total anti-oxidant, hydroxyl radical scavenging ability, reducing power activity, inhibition of lipid peroxide formation, DPPH activity metal chelating assay) in I. marginata leaves whole plant. res...

background and objective: gastric cancer is the fourth common and the second deadliest cancer worldwide, which the major causes of its prevalence are genetic factors and the lifestyle, such as eating fast foods, physical inactivity, environmental pollution, and other natural factors. method: this research was performed in human and animal cell bank of iranian biological resource center, and cyt...

background: blindness due to cataract is a major and important problem in pakistan. the problem is expected to increase in future due to increase in tobacco smoking. the aim of study was to look for the mechanism associated with metal deposition and its effect on antioxidant enzymes in lens of smokers in karachi, pakistan. methods: 20 cataract patients were randomly selected from out patient de...

conclusions: it was concluded that the elisa is a suitable method for large scale screening of antibodies against aspergilloma. the easy techniques have shortened the required time of tests (approximately 1.30 hours for our elisa, as opposed to 2.30 hours with commercial elisa kit). this may be a substantial benefit for large numbers of samples that should be tested. materials and methods: an i...
