    摘要: An aqueous solution containing fibrinogen is heated in the presence of at least a sugar, an amino acid and a magnesium salt to thereby inactivate virus(es) possibly contaminating said fibrinogen. According to this process, the inactivation of the contaminating viruses can be achieved while maintaining the activity of the fibrinogen. Thus a highly safe fibrinogen preparation of excellent qualities can be prepared on an industrial scale.

    摘要: A therapeutic and prophylactic agent for peptic ulcers which contains as an active ingredient a compound of the general formula (I): ##STR1## wherein R.sub.1 represents hydrogen or =O; R.sub.2 represents hydrogen or --OR.sub.5 ; R.sub.3 represents hydrogen or --OR.sub.6 ; R.sub.4 represents --OR.sub.7 in the case of the absence of double bond; R.sub.5, R.sub.6 and R.sub.7 each represents hydrogen or an organic residue;X represents group (A):.dbd.C.dbd.CH--COR.sub.8 (A) or group (B): ##STR2## wherein R.sub.8 represents alkyl, and R.sub.9 and R.sub.10 each represents hydrogen or an organic residue; with the proviso that when X represents group (A), then R.sub.1 and R.sub.3 both represent hydrogen, R.sub.2 represents --OR.sub.5 ; R.sub.4 represents OR.sub.7 and the bond between the carbon atoms to which X is attached and the carbon atom to which R.sub.4 is attached is a single bond, and when X represents group (B), then R.sub.1 represents .dbd.O, R.sub.2 represents hydrogen, R.sub.3 represents --OR.sub.6 and the bond between the carbon atom to which X is attached and the carbon atom to which R.sub.4 is attached is a double bond, or a pharmaceutically acceptable salt thereof, or a compound of the general formula (II): ##STR3## wherein R.sub.11 represents hydrogen or an organic residue, and R.sub.12, R.sub.13 and R.sub.14 each represents an organic residue, or a pharmaceutically acceptable salt thereof. The compounds of the general formulae (I) and (II) can be derived from compounds contained in a hot water extract of cinnamon.

    摘要: A process for purifying coagulation factor VIII which comprises contacting a plasma or a plasma fraction containing prothrombin complex and coagulation factor VIII (antihemophilic factor A) with diethylaminoethyl-crosslinked dextran to adsorb and remove the prothrombin complex from said plasma or plasma fraction. Coagulation factor VIII thus obtained can be administered to control the bleeding in hemophilia A patients.
