The specificity of anti-lymphocyte globulin (ALG) has been used to analyze an immune mechanism which is mediated by immunologically committed lymphoid cells to the apparent exclusion of humoral antibody. Rabbit antimouse lymphocyte globulin completely suppressed the immunity which can be passively transferred with Listeria-immune lymphoid cells from actively infected donors. When prospective do...

Antithymocyte globulin (ATG) is frequently effective therapy for aplastic anemia. Its mechanism of action is often assumed to be upon a lymphocyte inhibitor of hematopoiesis. However, specificity for T lymphocytes would not be anticipated from consideration of the method of preparing ATG. In fact, using flow microfluorometry and fluorescence immunohistochemistry, we have found that ATG binds to...

The serum proteinograms of 10 female Holstein calves fed milk either through conventional (COV) or step-down (STP) milk feeding methods at different ages were evaluated. Calves fed using the COV method were fed colostrum during the first 24 hours that they stayed with their respective mothers and received transition milk for another 2 days and later, and then milk at four liters/day for 59 days...

Rabbit antithymocyte globulin therapy (rATG) is a potent lymphocyte-depleting agent commonly used following renal transplantation to reduce the risk of acute rejection. Standard doses (7-10 mg/kg) of rATG result in profound lymphopenia and predispose patients to infection and malignancy. The effects of lower doses of rATG (LoD-rATG, 3-5 mg/kg) on peripheral blood lymphocytes (PBL) are as yet un...

cryptococcosis has become the fourth leading life-threatening opportunistic infection in patients with aids, but also occurs in non-aids patients. in view of the increasing numbers of infection during last decade in iran, use of rapid, sensitive and specific test for diagnosis of cryptococcal disease has become important than ever. we aimed to produce the reagents for latex cryptococcal antigen...

Naive T cells continuously migrate between the circulatory system and lymphoid organs, where they make dynamic contacts with rare dendritic cells (DCs) that strategically form an extensive dendrite network. In such a scenario, T cells spend most of their time quickly scanning the antigenic content of multiple DCs. These interactions provide the basis for efficient adaptive responses by increasi...

The immunologic response of graft recipients to antilymphocyte globulin has been studied. The clearance from the serum of (125)I-labeled antilymphocyte globulin was studied in 15 graft recipients previously treated with antilymphocyte globulin and in 4 control patients not previously treated with antilymphocyte globulin. The mean serum half-life of antilymphocyte globulin was 7.2 days in contro...

The current study aimed to explore the effect of Spirulina platensis (SP) inclusion at various levels in quail diets, terms their production performance, physiological traits, stress measurements, and immunological parameters under heat (HS) conditions. Four hundred Japanese (Coturnix japonica) chicks, one day old, were equally distributed into forty wire cages, cages placed two chambers with e...

Objective] Ba-Duan-Jin, formed in the 12th century, is an excellent traditional Chinese health exercises. Ancients likened it to “brocade (Jin)”, meaning its action is as elegant as brocade. The total movements are divided into 8 sections, so it is called “ Ba-Duan-Jin (8-section-action)”. Because of its simple action and significantly healthy effect, Ba-Duan-Jin is widely used to enhance physi...
