摘要:
A lymphokine in purified form or in the form of a lymphokine containing culture supernatant may be obtained by collecting lymphocytes from an animal or a human sensitized by an immunogen which induces the production of an antibody, selectively concentrating the lymphokine producing cells, forming a fused cell hybrid between the lymphokine producing cells and animal derived tumor cells, cloning the obtained hybrid, selecting the clone which spontaneously produces the lymphokine, culturing the clone to produce the lymphokine, and optionally recovering the lymphokine from the culture and purifying the lymphokine. This process is especially effective for producing interleukin 2, colony stimulating factor, T cells replacing factor, macrophage activating factor or immune interferon.
摘要:
Interleukin 2 of human cell origin, which has a specific activity of more than 2 x 10 5 units/mg protein and is free from other human lymphokines and monokines is a useful immunoprophylactic and immunotherapeutic agent per se or in combination with other chemotherapeutic agents and/or other immunotherapeutic agents.

摘要:
Novel ethylamine derivatives of the formula (I) and salts thereof are useful as antihypertensive agents. wherein A is a linking group wherein the linkage is formed by a carbon or nitrogen atom; B is an aryl-containing group; C is hydrogen or optionally substituted alkyl, aralkyl or aryl, or C may be bonded to A to form an optionally substituted alkylene bridge; Q is an aryl- or heterocyclic aryl-containing group; X is a linking group wherein the linkage is formed by optionally substituted alkylene having from 2 to 20 carbon atoms and/or one or more hetero atoms selected from nitrogen and sulfur.
