Delayed-type hypersensitivity reaction or type IV allergic reaction can cause different oral manifestations. They can be localized or diffusely visible on oral mucosa and usually appear 24-72 hours after antigen input. The antigens that cause this type of reaction are mostly external, such as contact allergens (particularly metals) and drugs. It has been shown that the most common oral manifest...
The staphylococcidal capability of populations of peritoneal macrophages in rabbits has been measured before and after repeated infections with Staphylococcus aureus. Such rabbits after infection showed delayed-type hypersensitivity to S. aureus antigens, but the staphylococcidal capability of the peritoneal macrophages was not increased. This result at the cellular level is in agreement with p...
Ulcerative dermatitis (UD) is common in captive sea turtles and manifests as skin erosions and ulcers associated with gram-negative bacteria. This study compared clinically healthy and UD-affected captive turtles by evaluating hematology, histopathology, immunoglobulin levels, and delayed-type hypersensitivity assay. Turtles with UD had significantly lower weight, reduced delayed-type hypersens...
In vivo tests may be used for the diagnosis of allergy to iodinated contrast media (ICM); however, the tests do not provide definitive diagnosis and are associated with risks for patients. Diagnoses based on in vitro tests are limited, and there are almost no relevant studies. Herein, the authors examined involvement of allergic reaction from a multilateral standpoint in 39 patients suspected o...
