The specific suppressing activity of passively administered antibody on 7S antibody synthesis against sheep and chicken red blood cells has been investigated at the cellular level using the indirect hemolytic agar-plaque technique. 7S antibody production was found to be sensitive to antibody-induced suppression. No inhibitory effect of transferred antibody was seen until 48 to 72 hr after admin...

serum samples from 201 hiv positive patients were collected to determine the seroprevalence of cmv infection in iranian hiv infected patients during march 2004 until march 2005 using conventional elisa kits. an antibody level of >1.1 iu/ml was considered positive. the seroprevalence of cmv infection was 94%.the maximum prevalence of cmv antibody was seen in patients with unsafe sex and idus. pr...

background: patients with end stage renal disease have higher incidence of infection dis-eases that is thought to be related to impaired immune system. objective: to determine the antitetanus igg antibody level in iranian hemodialysis patients with end stage renal disease and to find its association with sex, age, blood hemoglobin, serum albumin, dura-tion of dialysis, time of dialysis per week...

conclusions because 66% of students were anti-hav antibody negative and they will work as health care workers in future, our study suggest vaccinating all students accepted at aja university of medical sciences. results of total 270 students, 30 were female. their age ranged between 18 and 30 years old with the mean age of 20.58 years and just 34% of students had positive level of anti-hav anti...

background mumps, measles and rubella viruses lead to various kinds of complica- tions such as meningoencephalitis, deafness, congenital abnormalities and even cause mortality in malnourished patients,. since 2004, mmr vaccination in two series of one year of age and four to six years has been administered to iranian children as a part of routine vaccination program. recently, mmr vaccination s...

Neospora caninum is an obligate intracellular parasite causing abortion and reproductive failure in ruminants. Here, the seroprevalence of Neospora DNA and anti-Neospora antibodies and the correlation between the DNA and the antibody using polymerase chain reaction (PCR) and a new developed whole cell-based enzyme-linked immunosorbent assay (ELISA) in water buffalo (<...

introduction: zinc deficiency causes abnormalities in immune response. in chronic hemodialysis (hd) and continuous ambulatory peritoneal dialysis (capd) patients, impaired immune responses to vaccination have been reported. therefore, we performed a study to determine the correlation between serum zinc levels and immune response to hepatitis b vaccination in patients on dialysis. methods: a cro...
