Abstract: A dried product of an extract from inflammatory rabbit skin inoculated with vaccinia virus having an inhibitory activity for the production of a kallikrein-like substance is produced by admixing the extract with a saccharide, sugar alcohol or ascorbic acid before reaching dryness, and then drying the admixture to a solid form such as granules. The dried product may be employed to produce a solid preparation for oral administration, such as tablets, having an inhibitory activity for the production of a kallikrein-like substance.

Abstract: The present invention relates to an agricultural and horticultural composition inducing resistance in plants against salt- and water-stresses which comprises as an active ingredient an effective amount of at least one cyclic dipeptide of the following formula (I) or an agriculturally or horticulturally acceptable salt thereof; ##STR1## wherein each of R.sub.1 and R.sub.2, which may be the same or different, is a hydrogen atom or lower alkyl group, or R.sub.1 and R.sub.2 are joined to form pyrrolidine ring which may optionally have hydroxy group, and R.sub.3 is a hydrogen atom or hydroxy group.

Abstract: The present invention relates to a novel dipeptide having the formula (I): ##STR1## wherein R represents hydrogen atom or an amino-protecting group, Y represents hydrogen atom or hydroxy group which may optionally have protecting group, and X represents an acidic amino acid residue which may optionally have at least one protecting group; and pharmaceutical acceptable salt thereof. These dipeptides are useful as plant growth regulator.
