Resistance to Listeria monocytogenes was demonstrated in guinea pigs undergoing systemic delayed-type hypersensitivity reactions to bovine gamma globulin.

background iodinated x-ray contrast media are the most commonly used contrast agents in the world with an annual application of 40-50 million. new non-ionic con- trast agents are subdivided into low osmolar agents such as iopromide and iso-osmolar agents such as iodixanol. regarding different biochemical characteristics, these agents are different in the allergic reactions and contrast enhancem...

cow’s milk allergy is one of the most common food allergies in childhood. beta- lactoglobulin (β-  lg) is  a dominant  allergen in  cow’s milk. hydrolysis is  known as  an effective method to reduce the allergenicity of proteins. thus, the objective of this study was to compare the allergenicity of β-lg and its hydrolysates using an animal model. twenty four balb/c mice were divided into three ...

Purpose To provide information on the type of "hypersensitivity-friendly" components available for primary total knee arthroplasty (TKA) in the current market. Materials and Methods Implant manufactures were identified using the 2013 National Joint Registries of the United Kingdom and Sweden and contacted to obtain information about the products they offer for patients with metal hypersensiti...

Delayed hypersensitivity was produced in donor Lewis rats by sensitization with soluble protein antigens emulsified in complete Freund's adjuvant. Cells of their thoracic duct lymph were collected for varying periods of time and transferred intravenously to isogenic Lewis recipients. With this model the following conclusions were reached: 1. Delayed hypersensitivity was transferred by thoracic ...

The results of this study of allogeneic restriction of passively transferred delayed sensitivity to Listeria antigens serve to illustrate the complexity of in vivo models. They show that the H-2 restriction observed when delayed-type hypersensitivity was transferred between H-2-congenic strains was no more severe than the restriction observed when delayed-type hypersensitivity was transferred b...
