Delayed-type cutaneous reactivity to 2,4-dinitrochlorobenzene and 2,4-dinitrofluorobenzene in guinea pigs was transferred passively by fluids in which leukocytes from sensitive animals were incubated. Cells from peritoneal exudates, lymph nodes, and alveolar washings were employed. The cell-free transfer material was dialyzable, of small molecular size, and stable to 56 C for 30 min and -65 C f...

This study investigated the effect of Chondria crassicaulis ethanol extract on degranulation rat basophilic leukemia-2H3 cells and 2,4-dinitrochlorobenzene-induced atopic dermatitis-like skin lesions in Bagg Albino/c mice. General properties (proximate analysis, total phenol flavonoid) were measured; moreover, beta-hexosaminidase release cytotoxicity cells, severity dermatitis, production cytok...

CdSe quantum dots (QDs) were synthesized in oleic acid and octadecene medium under high-temperature and dispersed in chloroform. Nitroaromatic explosives and their relative compounds, 2,4,6-trinitrotoluene (TNT), 2,4-dinitrotoluene (DNT), nitrobenzene (NB), 2,4-dinitrochlorobenzene (DNBCl) and p-nitrotoluene (NT) can obviously cause the fluorescence quenching of the synthesized QDs. Under the o...

Induction of in vivo dinitrochlorobenzene (DNCB) sensitization has been corre lated with in vitro cultured lymphocyte transformation in 21 patients with histologically confirmed sarcoidosis and 21 matched control subjects. Failure to sensitize with DNCB was noted in 71 percent of patients with sarcoidosis and in 14 percent of controls. Poor lymphocyte transformation occurred in 90 percent of pa...

One hundred thirteen tumors in 5 dinitrochlorobenzene (DNCB)-sensitized patients with multiple basal cell carcinomas were treated with topical DNCB. Thirty-six of the 113, or 32%, showed complete clinical regression, for periods of 5 to 18 months. An additional 29% (33 or 113) showed partial regression. DNCB induced only 15 to 25% complete regression in 4 of the 5 patients, whereas 21 of 30, or...
