摘要:
Monoclonal antibodies immunospecific for the neutrophil chemotactic factor, IL-8, have been humanized by reshaping the variable regions to conform more closely to human counterparts. These antibodies are useful in immunoassays to detect IL-8 and as ligands on immunoaffinity columns for purification of human IL-8. In addition, the humanized antibodies have an antiinflammatory effect in patients.

A METHOD FOR DETECTING A CANCER TISSUE BY MEASURING A POLAROGRAPHIC WAVE IN THE RANGE OF FROM -1.0 TO -2.0 V. VS. S.C.E. ON AN EXTRACT OF A SUSPECTED TISSUE AT A PH VALUE OF FROM 5 TO 7 IN THE PRESENCE OFF AN ALKALINE METAL HALIDE TO DETERMINE THE PRESENCE OF A POLAROGRAPHIC WAVE AT AROUND -1.90 TO -1.95 V. VS. S.C.E. WHICH IS A CHARACTERISRIC OF THE CANCER TISSUE IS DISCLOSED
摘要:
A WATER-INSOLUBLE ANTI-TUMOR ACTIVE SUBSTANCE IS PRE PARED FROM THE LIVING CELLS OF HEMOLYTIC STREPTOCOCCI BY LYSING THE CELLS OF HEMOLYTIC STREPTOCOCCI WITH A LYTIC ENZYME AND COLLECTING A WATER-INSOLUBLE FRACTION WHICH CORRESPONDS TO A PROTOPLAST MEMBRANE FRACTION OF THE CELLS. THE PREPARATION OF THE ANTI-TUMOR SUBSTANCE IS FAR SUPERIOR IN THE ANTI-TUMOR ACTIVITY TO THAT OF WATER-SOLUBLE FRACTION AND HAS LESS INFLAMMATION-, FEVER- AND PAINCAUSING PROPERTIES THAN ANY ONES OF PRIOR ART.
摘要:
WHEREIN R1, R2, R3 AND R4 ARE SELECTED FROM THE GROUP CONSISTING OF METHYL AND ETHYL, WITH OR WITHOUT CONTAINING ONE OR MORE PESTICIDES SELECTED FROM THE GROUP CONSISTING OF ORGANO-CHLORIC PESTICIDES, CARBAMATE PESTICIDES AND ORGANO-PHOSPHORUS PESTICIDES IS DISCLOSED.
摘要:
The hemostatic agent of the present invention is obtained by the following process: An aqueous solution of Trimeresurus okinavensis venom is treated with almost the same volume of an organic solvent such as chloroform, ether and ethyl acetate to remove lipids, and the water layer is collected and dialysed against a distilled water. Dyalysate is passed through dextran gel column, said dextran gel having a molecular weight fractionation range of 1,000 to 50,000, to adsorb thereon and eluted with phosphate buffered solution (pH 7 - 8). The fraction having strong coagulating activity is collected in the recalcification test and passed through a column filled with a basic ion exchange resin to allow the active substance to adsorb thereon and eluted with ethyl acetate (pH about 7). The fraction having the highest blood coagulating activity is collected in the recalcification test, and lyophilised.
摘要:
A cell wall lytic enzyme which possesses an ability to lyse the cell wall of Chlorella, yeasts, etc. is produced by aerobically culturing a microorganism belonging to Genus Micropolyspora which produces a cell wall lytic enzyme in a medium containing assimilable carbon sources, assimilable nitrogen sources and essential inorganic salts and organic nutrients until a substantial amount of the enzyme is accumulated in said medium and isolating said enzyme from the medium, and, if desired, subjecting the thus obtained crude enzyme to the purification step of salting out or dialysis to obtain a purified enzyme solution and further subjecting the enzyme solution to freezedrying to obtain a powder preparation of said enzyme.
THE ACID-ADDITION SALTS AND QUATERNARY AMMONIUM SALTS THEREOF, WHEREIN R IS SELECTED FROM THE GROUP CONSISTING OF BENZYL, METHYLBENZYL, ISOPROPYLBENZYL, CHLOROBENZYL AND PHENYLETHYL, AND R'' IS SELECTRED FROM THE GROUP CONSISTING OF HYDROGEN, ACETYL AND BENZYL.
