it has been recognized that acute and chronic stress has an impact on the immune system. acute stress may have a stimulating effect on the immune system, while in the case of chronic stress specially depression, the immune system could be down-regulated. however, an association between depression and a higher number of circulating white blood cells with increased activity has been reported. ele...

cytotoxic effects of obturation materials were tested in presence and absence of endotoxin on human monocytes in vitro.human monocytes from thp-1 cell line were cultured. three millimeters from the tip of each resilon and gutta percha points were cut and directly placed at the bottom of the culture wells. cultured cells were exposed to gutta percha (groups g1 and g2) and resilon (r1 and r2). te...

PROBLEM Accumulating data suggests that aberrant immune responses during retrograde menstruation may be involved in the development of endometriosis. METHOD OF STUDY The role of immunology in the etiology of endometriosis is reviewed and summarized from the available literature. RESULTS Immunologic factors may affect a woman's susceptibility to implantation of exfoliated endometrial cells. ...

The ability of cancers to evade immune surveillance and resist immunotherapy raises a fundamental question of how tumor cells survive in the presence of a competent immune system. Studies to address this question have primarily focused on mechanisms by which tumor cells avoid recognition by or induce tolerance in the immune system. However, little is known about whether cancer cells also acquir...

The role of natural killer (NK) cell function in HIV disease especially in the setting of long-term antiretroviral therapy (ART) and viral suppression is not fully understood. In the current study, we have investigated NK cell activation in healthy controls and aviremic ART-treated HIV+ subjects with different degrees of immune restoration. We performed a cross sectional study in 12 healthy con...

OBJECTIVES The aim of this study was to investigate the effects of massage therapy (MT) on the immune system of preterm infants. The primary hypothesis was that MT compared with sham therapy (control) will enhance the immune system of stable premature infants by increasing the proportion of their natural killer (NK) cell numbers. METHODS A randomized placebo-controlled trial of MT versus sham...

A morphologic study of normal and AET-treated lymphocytes than in their AET-treated lymphocytes exposed in untreated counterparts. These results vitro to cytotoxic antibody and compleconfirm the serologic finding that AETment (C) has been carried out using both treated lymphocytes possess a higher transmission and scanning electron microthan normal susceptibility to the damagscopy. The abnormal...

Combination antiretroviral therapy (cART) has transformed the outcome of human immunodeficiency virus-1 (HIV-1) infection from a severe immunodeficiency syndrome to a chronic clinically manageable disease. However, patients require lifelong therapy and are at risk of developing nonAIDS complications (1, 2). Despite viral suppression in patients on cART, HIV-1 persists via the establishment of a...

Lycium barbarum polysaccharide (LBP) is the major function component of Lycium barbarum L. and has been previously reported to induce the phenotypic and functional maturation of dendritic cells (DCs) as well as activating T lymphocytes. In the current study, the immunologic cytotoxicity promoting effect of LBP was assessed and the underlying mechanism was explored. The impact of LBP on the phen...
