Title: Suppression of allergic reactions by transdermal administration of allergens in conjunction with or conjugated to toxin subunits or fragments thereof
Inventor: CZERKINSKY CECIL
IPC: A61K47/48
Filed: 2002-05-23
Abstract: The present invention discloses the use of the non-toxic cell-binding B subunit of CT (CTB), and holotoxin CT that is devoid of ADP-ribosylating activity, as adjuvants for enhancing transcutaneous immune response to a co- administered protein allergen. It was found that topical administration of C TB to mice induced serum antibody response against itself comparable to those evoked by CT, but was inefficient at promoting systemic antibody responses against an admixed prototype protein allergen. To the contrary co- administration of either CT or CTB with allergen led to vigorous antigen- specific T cell proliferative responses in lymph nodes draining the cutaneou s site of administration and at distant systemic sites. Consistent with these observations, it was found that CTB selectively potentiated Th1-driven responses without affecting Th2-dependent responses. Cutaneously applied CT enhanced serum IgE responses to a co-administered allergen, while CTB partially suppressed epicutaneously induced IgE responses to the same allerg en.

Title: Catalyst and process for decomposing carbonyl sulfide and hydrogen cyanide
Inventor: HOSOYA EIICHI
IPC: B01J21/12
Filed: 2002-10-30
Abstract: A solution of a chromium compound is impregnated into a silica-alumina carrier made of alumina and containing 1 to 5 weight % of silica relative to the weight of the carrier, thereby to obtain a decomposing catalyst carrying 10 to 15 weight % of chromium oxide relative to the weight of the catalyst in terms of Cr2O3. By contacting mixed gas obtained through partial oxidation of heavy oil and/or coal with the decomposing catalyst, COS and HCN contained in the mixed gas are decomposed/removed. In this case, transition of alumina into boehmite can be suppressed owing to coexistence of silica and chromium oxide, so that COS and HCN can be decomposed by highly active catalytic reactions over a long time.
