THE EFFECT OF ASCORBIC ACID ON BLOOD HISTAMINE LEVEL AND DELAYED-TYPE HYPERSENSITIVITY IN GUINEA PIGS
The effect of ascorbic acid on blood histamine level and delayed-type hypersensitivity was studied in thirty male guinea pigs. Animals were sensitized to B.C.G., trichophytin and mallein during the first four weeks. The diet was ad libitum during this period. After this "sensitization period" animals w er e tested intradermally with tuberculin, trichophytin and mallein. The number and diam...
متن کاملDelayed Hypersensitivity Induced in Guinea Pigs
A delayed hypersensitivity to 7,12-dimethylbenz(a)anthracene was elicited in guinea pigs after contact sensitization. This sensitivity was characterized by its time of appearance, histology, specificity, and transfer characteristics. The reaction had its maximal dermal reactivity 24 hr after challenge, was characterized by a mononuclear cell infiltration, demonstrated immunological specificity,...
