This study was performed in 2003-05 to determine the serological status of a sample of pregnant women as a preliminary study for the rubella vaccination programme. Out of 965 pregnant women attending health centres affiliated to Tehran University of Medical Sciences for prenatal care, the estimated rubella immunity rate was 91.1% (95% CI: 89.3%-92.9%) and the nonimmunity rate was 8.9% (95% CI: ...

The role of cytokine- and T helper (Th)-dependent lung mucosal antifungal immunity in murine invasive pulmonary aspergillosis (IPA) was investigated. Intact or leukopenic DBA/2 mice were resistant or highly susceptible, respectively, to infection caused by multiple intranasal injections of viable Aspergillus fumigatus conidia. Resistance was associated with unimpaired innate antifungal activity...

The aim of this study was to determine level of serum IgA, IgG and IgM in patients with OLR as indicators of humoral immunity which might reflect cell-mediated immunity. This study was conducted on 30 patients (age 60.17 +/- 11.75) with clinically and histopathologically confirmed diagnosis of OLR and 30 healthy controls (age 56.16 +/- 11.82) Determination of serum IgA, IgG and IgM was performe...

background: endometriosis is a frequent gynecologic disease with a severe impact on the quality of life in the affected women; its pathogenesis is yet to be fully understood, with an altered immunity as a possible key factor. the present study aimed to investigate the serum anti-inflammatory cytokine profile in the patients with endometriosis compared with the healthy controls. materials and me...

Antigenically evolving pathogens such as influenza viruses are difficult to control owing to their ability to evade host immunity by producing immune escape variants. Experimental studies have repeatedly demonstrated that viral immune escape variants emerge more often from immunized hosts than from naive hosts. This empirical relationship between host immune status and within-host immune escape...

abstract background and aims: medical students are exposed to various infectious diseases during their clinical training period, including measles and rubella. in iran, to control the outbreaks of measles and rubella a mass vaccination campaign was conducted on 2003. the present investigation evaluates immunity to measles and rubella in a group of babol medical students and determines the preva...

the aim of the present work was to determine whether the administration of melatonin or l­-tryptophan (a precursor of melatonin) affects the immune responses and performance of broilers during induced exposure to aflatoxins in feed. the study was conducted from 0-6 weeks comprising six dietary treatments in triplicate with10 chickens in each replicate. the diets were formulated to supply 23% cr...

Melatonin is an important secondary messenger in plant innate immunity against the bacterial pathogen Pseudomonas syringe pv. tomato (Pst) DC3000 in the salicylic acid (SA)- and nitric oxide (NO)-dependent pathway. However, the metabolic homeostasis in melatonin-mediated innate immunity is unknown. In this study, comparative metabolomic analysis found that the endogenous levels of both soluble ...

The brassinosteroid-SIGNALING KINASE (BSK) belongs to the receptor-like cytoplasmic kinase XII subgroup. BSK1 regulates development and immunity in Arabidopsis. However, the function of rice (Oryza sativa) BSK1 is largely unknown. Here, we report that the expression level of OsBSK1-2 is induced after a chitin or fagellin22 (flg22) treatment. Silencing OsBSK1-2 in rice results in compromised res...
