Abstract: A drug for prevention and therapy of diseases caused by fibrinoid formation or thrombus formation, as well as a model animal of fibrinoid formation or thrombus formation in the lung is disclosed. The drug for preventing and treating diseases caused by fibrinoid formation or thrombus formation in the lung according to the present invention comprises an inhibitor of interleukin 6 as an effective ingredient. The model animal of the diseases caused by fibrinoid formation or thrombus formation in the lung is a rat in which fibrinoid formation or thrombus formation actually occurs by induction with interleukin 6.

Abstract: Leukocyte chemotactic factors such as interleukin-8 and MCAF, and inductive substances therefor were revealed to have proconceptive activities. These activities include promoting ovum growth and fertilized ovum implantation, and are exhibited by a sole substance. Accordingly, it has been shown that such substances can be used in drugs concerning medical treatment for infertility, and further, can be used in veterinary and livestock industry fields such as reproduction of industrial animals or species preservation of rare animals.

Abstract: The present invention offers the serine protease exhibiting a biological activity which a polypeptide having an amino acid sequence shown in FIG. 1 shows, the serine protease precursor where a cleavable peptide or signal peptide connects with the N-terminal of the said serine protease, and the gene encoding them. The serine protease being useful in medical treatment fields can be manufactured in large quantities by the present invention.Moreover, the present invention offers the DNA sequence coding a transcription controlling region contained in the chromosomal gene of the serine protease of a human myeloid cell. This sequence is the transcription controlling region being necessary for the gene expression being specific to a human leukocyte or erythrocyte.

Abstract: A therapeutic agent for treating wounds having properties and actions different from those of growth factors and proteins inducing growth factors, which have strong therapeutic effect is disclosed. The therapeutic agent for treating wounds according to the present invention comprises monocyte chemotactic and activating factor or a variation thereof having a monocyte-attracting property or a derivative of said monocyte chemotactic and activating factor or said variation thereof.

Abstract: The present invention relates to compositions containing human interleukin-6 with sugar chains, a process for preparing human interleukin-6 by culturing cells in a medium containing ascorbic acid or any of its derivatives, and a process for purifying a crude raw human interleukin-6 solution by chromatography using a carrier with heparin bound. The present invention has allowed the production of high quality human interleukin-6 compositions with sugar chains, and their application to medicines. Furthermore, it has established a process for massproducing human interleukin-6.

Abstract: Angelic acid or esters thereof which are useful as perfume materials are prepared by isomerizing tiglic acid or an ester thereof with an organic sulfinic acid as the catalyst, and novel esters of angelic acid represented by the formula ##STR1## wherein R represents 3-hexenyl, 3-methyl-2-butenyl, 3-methyl-3-butenyl, 3-methyl-2-pentenyl, 3-methyl-4-pentenyl, CH.sub.3 (CH.sub.2).sub.l - (in which l is an integer from 5 to 9), cyclopentyl, cyclohexyl, 2-methylpentyl, .alpha.-methylbenzyl, neryl or furfuryl are provided as part of said esters of angelic acid.

Abstract: The degradation of prostaglandins E is prevented or minimized by combining prostaglandins E with methylhesperidin.
