Lymphocyte phytohemagglutinin (PHA) responsiveness was found suppressed in both rubella sero-negative and sero-positive recipients of RA 27/3 strain of live attenuated rubella vaccine; the suppression was readily demonstrable only when a suboptimal dose of PHA was applied in the test. Lymphocytes from sero-negative vaccinees, which initially showed little or no in vitro response to concentrated...

Objective: An experiment was conducted to investigate the effects of citrus brown snail powder as a source of calcium on growth performance, tibia characteristics, immune response and blood metabolites in broiler chickens.  Methods: One hundred and eighty 1-day old chicks were randomly distributed into four treatments, each of which had three replicates. Each replicate contains 15 chicks. The t...

Background: The immunogenic Brucella abortus ribosomal protein L7/L12 is a promising candidate antigen for the development of subunit vaccines against brucellosis. Objective: This study was aimed to evaluate the protection of recombinant Human Serum Albumin (HAS)-L7/L12 fusion protein in Balb/c mice. Methods: The amplified L7/L12 gene was cloned in pYHSA5 vector, pYHSA5-L7/L12 construct was tra...

Objective: This study aimed to evaluate the prognostic importance of diabetes mellitus, hematologic and biochemical test findings including neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte systemic inflammation response index triglyceride-glucose in patients with Bell’s palsy compare these results healthy subjects.Material Methods: The included 75 incomplete palsy.and 24 subjects as contr...

The effects of the human and bovine LSF (derived from sera) as well as their purified fractions were studied on murine lymphocytes reactions indicated by blast transformation (BT) assay, mixed lymphocyte culture (MLC) and IgG synthesis. The results indicated that bovine lipid suppressor factor (LSF) has significant immunosuppressive activity on lymphocytes proliferation both in BT and MLC ...

it   was   recently   demonstrated   that   5-(5-nitrofuran-2-yl)-1,   3,   4-thiadiazoles   with piperazinyl-linked benzamidine substituents are effective in vitro against leishmania major. following on this evidence, we used colorimetric assay of acid phosphatase activity in the promastigotes  as  an  indicator  for  cell  viability.  also  we  studied  the  effect  of  these compounds on ind...

Seventy-seven adult mongrel dogs underwent left lung transplantation to study the immunological detection of posttransplant rejection response using the lymphocyte blastogenesis assay. Experimental animals were divied into 3 groups; control autotransplantation (4 dogs), control allotransplantation (32 dogs) and immunosuppressed allotransplantation (41 dogs). The lymphocyte blastogenesis assay i...
