Abstract: A novel anti-IL13 receptor ?1 antibody having an activity of inhibiting a cell response by IL13, in particular, having an activity of inhibiting the cell response by IL13 but not inhibiting the cell response by IL4, a characteristic amino acid sequence in a variable region thereof, and a method of detecting IL13 receptor ?1 in a sample using the same are provided.

Abstract: It is intended to provide a novel low-molecular weight amine derivative, that is absorbed well, has low toxicity, and has an excellent human ?-tryptase inhibitory activity with extremely high selectivity, a pharmaceutically acceptable salt thereof, and a medicine containing the same as an active ingredient. The medicine of the present invention is efficacious as a prophylactic/therapeutic agent for diseases in the crisis and evolution of which are considered to be attributed to ?-tryptase, for example, respiratory diseases, allergic diseases, inflammatory bowel diseases, hyperprolliferative skin diseases, vascular edema and rheumatoid arthritis.

Abstract: A method of purifying cooling water used in nuclear reactors, which comprises contacting said cooling water with a hydrotalcite compound of the following formulaM.sub.1-x.sup.2+ M.sub.x.sup.3+ (OH).sub.2 A.sub.x/n.sup.n-. mH.sub.2 O (1)wherein M.sup.2+ represents a divalent metal cation, M.sup.3+ represents a trivalent metal cation, A.sup.n- represents an anion having a valence of n, and x and m satisfy the following expressions0<x<0.50.ltoreq.m<1or a calcined product thereof obtained by calcination at a temperature of up to about 900.degree. C.; and a purifying agent used therefor.
