    摘要: Peptides of the formula R.sup.1 -His-Asp-Glu-Ala-R wherein R.sup.1 is Ala-Gln, and R is a polypeptide residue with up to 50 amino acid residues, and wherein one, more or all of the amino acid residues in R.sup.1 and/or R independently may be omitted, can be used to augment cell mediated cytotoxicity and thereby to treat cancers and viral infections. These peptides may be prepared by proteolytic digestion of Staphylococcus aureus protein A, as well as by protein synthesis, recombinant DNA methods or any other methods known in the art.

    摘要: The invention relates to a novel purified polypeptide which is recoverable from porcine pancreas glands. The amino acid composition of the said polypeptide has been determined to be as follows:Trp (2), Lys (4), His (1), Arg (5), Asx (10), Thr (3), Ser (9), Glx (12), Pro (12), Gly (6), Ala (6), Cys 1/2 (14), Val (7), Met (2), Ile (3), Leu (1), Try (2), Phe (7), wherein the determinations are subjected to the usual error of .+-.10 percent of the indicated figures. The partial amino acid sequence comprising a total of 45 amino acids from the N-terminal, is believed to be: ##STR1## wherein pyrGlu (residue 1) stands for pyroglutamic acid. The purified polypeptide is of utility as a medicament, for example as a spasmolytic agent, as an agent for treatment of gastroduodenal ulcers and as a diagnostic aid.
