In the present report, I attempted to identify the nature of humoral and cellular factors in heterotransplantation immunity, assuming that the former would confer on the animals transplantation immunity by passive immunization with serum, while the latter would be adoptively transferred to recipients with sensitized cells. A group of mice was inoculated with rat ascites hepatoma cells. Eighteen...
effect of adding melissa officinalis aqueous extract was studied on immune response and performance in 200 ross 308 broiler chicks in a completely randomized design with five treatments and four replicates and 10 observations per replicate. the amounts of 0 (control), 0.5, 1, 1.5 and 2 ml/l lemon balm extract were added in drinking water for 42 days. humoral immunity was evaluated by injection ...
Background: Tonsils and adenoids are involved in both local immunity and immune surveillance for the development of immune defense mechanisms. A number of investigators have found decreased immunoglobulin levels after adenotonsillectomy while others have failed to find significant changes. The effects of adenotonsillectomy on the cellular immunity of children have not been investigated extensiv...
Exposure to high fluorine can cause toxicity in human and animals. Currently, there are no systematic studies on effects of high fluorine on blood cellular immunity and humoral immunity in mice. We evaluated the alterations of blood cellular immunity and humoral immunity in mice by using flow cytometry and ELISA. In the cellular immunity, we found that sodium fluoride (NaF) in excess of 12 mg/K...
background: pandemic flu had at least two waves in iran. knowing how many of the general population were already exposed to this infection has a major impact on na-tional preventive measures. as of december 30, 2009, a total of 3672 confirmed cases of human infection with a novel influenza a (2009 h1n1) virus had been reported in iran with 140 deaths. objective: in this study we aim to measure,...
objective: turmeric (curcuma longa linn) is a medicinal plant that contains curcumin. there is a growing interest in using curcumin powder (cp) as feed additives for antioxidative and antimicrobial properties to improve human health. this study was conducted to determine the appropriate levels of cp on blood parameters, immunity, and histology of jejunum in hens. materials and methods: a total ...
Background: Immunisation remains critical in prevention of serious COVID-19 infection. This study aimed to characterise the prevalence humoral and cellular immunity patients on maintenance dialysis a nephrology centre 8 months after vaccination onset. Methods: Real-world single-centre cross-sectional enrolling peritoneal haemodialysis. Humoral response was measured as specific IgG (anti-spike p...
