studies have demonstrated that plant extracts possess various biological characteristics, including immunomodulatory activity. heracleum persicum desf. (apiaceae), a medicinal plant native to iran, was studied for its immunomodulatory activity. immunomodulatory activity of different doses of an aqueous extract of h. persicum, was evaluated in female swiss albino mice. mice were treated with thr...

objective: the immunomodulatory effect of geranial, geranial acetate, gingerol, and eugenol essential oils were evaluated by studying humoral and cell-mediated immune responses. materials and method: the essential oils were evaluated for immunomodulatory activity in in vivo studies, using rats as the animal model. the essential oils were tested for hypersensitivity and hemagglutination reaction...

humoral immune response of vaccine-i (supermatent from sonicated sporulated oocyst), vaccine –ii (sediment from sonicated sporulated oocyst) and vaccine –iii (un-sonicated sporulated oocyst) against conccidiosis in chickens was determined by indirect haemagglutination (iha) test. iha antibody titre was significantly higher (p

Haemagglutination is a specific form of agglutination and is used when antibodies bind to red blood cells, which act as a particulate antigen. Red blood cells are particularly useful targets as they are readily available and agglutination is observable using the naked eye. This technique is commonly used to determine the titre of an antibody (Ab), for blood grouping and viral quantification. In...

To elucidate inconsistencies in rubella haemagglutinin assays the components of the assay technique were examined. The results of carefully controlled assays of rubella haemagglutinin antigens from different sources in various plates and diluents with four species of indicator cells are reported. The quality and quantity of gelatin in the dextrose-gelatin-veronal buffered diluent commonly used ...

The titre of antibodies to Toxoplasma gondii was compared in 1985 sera by use of an indirect haemagglutination test (ToxHA test--Wellcome Reagents Ltd) and the dye test. Sera from 42 patients with clinical or serological indications of recent toxoplasmosis were also examined to determine if the ToxHA test would be of value in detecting early stages of the disease. Nine recent cases of lymphaden...
