background : this study aimed to compare three staining methods including: calcofluor white, chromotrope and quick hot gram chromotrope used in diagnosis of intestinal microsporidial spores . methods : one hundred and seventy five stool specimens were collected from patients referred to laboratory of intestinal protozoology at the school of public health, tehran university of medical sciences d...

Background: During pregnancy, the maternal immune system is in close contact with cells and tissue from the semiallogenic fetus .The human leucocyte antigen (HLA) class Ib molecules, HLA-E, -F and -G, are expressed at the materno-fetal interface. Because of the apparent immunoregulatory functions of these proteins, they may be involved in successful acceptance of the semi-allogenic fetus during...

The principal advantages of simultaneously recording from, and staining of single neurons, buried deep in tissue, is obvious and need not be stressed. Particularly in insects, where most cell somata are electrically silent, there is so far no way to correlate neuronal activity with a particular cell other than to penetrate and to label small fibers simultaneously (Hengstenberg, 1971). Great eff...

By PETER M. MARCUSE AND JOAN COCHRAN M ANY CYTOCHEMICAL methods have been used in hematologic studies. As applied to leukocytes, these include the demonstration of phosphatase activity,’ the visualization of phosphorylase,2 and the staining of intracytoplasmic glycogen.3 Intracellular visualization of dehydrogenase activity in leukocytes can be achieved by the use of the tetrazolium salts, whic...

The toxic effects of thioacetamide (TAA) and carbon tetrachloride on the human body are well recognized. In this study, we examined whether TAA intoxication can induce kidney leukocyte infiltration (measured as common antigen CD45) associated with augmentation reactive oxygen species (ROS)/tumor necrosis factor-alpha (TNF-α) axis, biomarkers injury without metformin treatment. Rats were either...

Bitter taste is mediated by bitter receptors (T2Rs), a multigene family of G-protein-coupled on the tongue. 25 different T2Rs are known to be expressed. have recently been found in several regions body, and T2R38 has reported expressed lymphocytes peripheral blood. Atopic dermatitis (AD) most common chronic inflammatory skin disease, skin-infiltrating T cells play pivotal role development maint...
