Ingested arsenic localizes to the skin [2, 7], where it may alter cutaneous immune responses. The delayed type hypersensitivity (DTH) response to 2,4-dinitrochlorobenzene (DNCB) was suppressed in Bowen s disease patients [8], Langerhans cells (LC) in skin lesions and perilesioned skin from arsenic-induced Bowen s disease and carcinomas were reduced in number and were morphologically altered, having a notable loss of dendrites [9], These data suggest that chronic exposure to arsenic in drinking water may... 

Over the past decade, there have been considerable advances in our understanding of the immunobiological mechanisms that result in the quality of immune response necessary for the induction of chemical respiratory allergy. Experiments designed to characterize immune responses in mice to chemical sensitizers have demonstrated that different classes of chemical allergen stimulate the development of qualitatively discrete immune responses consistent with the selective emergence of functional subpopulations of T lymphocytes [16]. Thus, topical exposure of BALB/c strain mice to chemical contact allergens such as 2,4-dinitrochlorobenzene (DNCB) results in the induction of...

Also epithelial cells—enterocy tes may be APC cells in humans—present antigens to T CD8 lymphocytes, which produce antigen nonspecific TCR (Mayer and Shlien, 1987). In rats, on the other hand, selective immunosuppression has been observed which was dependent on antigen-specific T lymphocytes (Bland and Warren, 1986) releasing TGI P, present in Peyer s patches as soon as within 24-48 h of the intake of small antigen doses (Lider et al., 1989). Occurrence of food tolerance may be due to some haptens, e.g., DNCB (2,4-dinitrochlorobenzene) administered to mice orally, according to Galliaerde et al. (1995).

In the last few years, interest in triterpenes as anti-inflammatory agents and their mechanisms of action has also increased greatly. Oleanolic acid and ursolic acid have been recognised to have anti-inflammatory activity in carrageenan-induced paw edema in rats or mice, adjuvant-induced arthritis in rats, etc. Oleanolic acid, in addition, was able to suppress the delayed hypersensitivity reaction in mice induced by dinitrochlorobenzene (DNCB). These effects are attributable to different mechanisms of action ranging from the inhibition of histamine release to inhibition of complement activity [1,58]. 

Pyrrolnitrin is an antimycotic paranitro compound used in Italy and Japan. Two cases of allergic contact dermatitis to pyrrolnitrin in a cream base were reported in one, a positive patch test to the related dinitrochlorobenzene (DNCB) was found (Meneghini and Angelini 1975).
