Abstract: As shown by the following reaction formula, disclosed is a fluorine-containing hydroxyaldehyde production method, including the step of obtaining a fluorine-containing hydroxyaldehyde represented by the general formula (1) by reacting a fluorine-containing ketone represented by the general formula (4) and an aldehyde represented by the general formula (5) in the presence of an organic base selected from a heterocyclic compound which contains a nitrogen atom in its ring or a tertiary amine. By this production method, it is possible to obtain the fluorine-containing hydroxyaldehyde in a high yield. Furthermore, it is possible to easily obtain in high yields a fluorine-containing propanediol, which is a derivative of this fluorine-containing hydroxyaldehyde, and a fluorine-containing alcohol monomer by using the same.

The polypeptide comprises a peptide unit of formula (1), and optionally one or more units of formulae (2) to (3): (1) [—(OC—(CH2)m—CO)p-(Pro-Y-Gly)n-]a; (2) [—(OC—(CH2)m—CO)q-(Z)r-]b; and (3) [—HN—R—NH—]c, wherein “m” is 1-18 , “p” and “q” are identical or different, and each is 0 or 1 , “Y” is Pro or Hyp, and “n”1-20 ; “Z” is a peptide chain comprising 1-10 amino acids, “r”1-20 , and “R” is a linear or branched alkylene group; the molar ratio of “a” to “b”[a/b] is 100/0 to 30/70 ; when p=1 and q=0, c=a, when p=0 and q=1, c=b, when p=1 and q=1, c=a+b, and when p=0 and q=0, c=0; and the polypeptide shows a peak of molecular weight in a range from 1×104 to 100×104 in the molecular weight distribution.

Abstract: The present invention provides a capsicum containing lachrymator. The lachrymator comprises a nonflammable carrier and capsicum. The nonflammable carrier comprises propylene glycol, ethyl alcohol and water. In one preferred embodiment the lachrymator comprises about 0.3 percent by weight capsicum, about 14.7 percent by weight propylene glycol, about 35 percent by weight ethyl alcohol and about 50 percent by weight water.

Abstract: A pharmaceutical composition comprises an immune complex of an allergen and a purified antibody specific thereto, the allergen being selected from a specific subclass of antigen which causes immediate hypersensitivity that is mediated by IgE antibody, and a pharmacologically acceptable carrier or diluent. The method of using the compositions in the treatment of immediate hypersensitivity to the allergen is also described.

Abstract: A method for dispensing a protective fluid is set forth wherein a container is provided formed with a transparent storage portion threadedly receiving a cap thereto. The cap includes a lower end formed with a series of alignment bores for receiving tubular projections integrally formed coaxially upon an exterior surface of the portion of the cap to enable reciprocation of the upper portion relative to the lower portion. Positioning rods are positioned adjacent each of the bores to provide an abutment to enable effective alignment of the projections with the bores. The container is filled with a lemon juice concentrate, whereupon the container is prepared for transport by an individual. The upper portion of the cap may be rotated relative to the lower portion of the cap to permit reciprocation and projection of the lemon juice spray upon an attacker imposing oneself upon an individual.

Abstract: In the treatment of allergy, desensitization is effected by administering the allergen in admixture with an antibody thereto, the antibody being present in a molar excess. The antibody is preferably one raised in the patient.
