Abstract: This invention relates to a novel method for the delivery of cytotoxic drugs to tumor cells by the administration of a tumor-specific antibody-enzyme conjugate that binds to the tumor cells, and the additional administration of a prodrug that is converted at the tumor site, in the presence of the antibody-bound enzyme, to an active cytotoxic drug. According to preferred embodiments of this invention, antibody-enzyme conjugates containing the enzyme, alkaline phosphatase ("AP"), have been used in conjunction with the novel prodrug, etoposide-4'-phosphate or 7-(2'-aminoethyl phosphate)mitomycin or a combination thereof, to effect killing of tumor cells. According to another embodiment of the invention, an antibody-enzyme conjugate containing the enzyme, penicillin V amidase ("PVA"), has been used in conjunction with a novel prodrug, N-(p-hydroxyphenoxyacetyl)adriamycin to effect killing of tumor cells.

Abstract: The present invention provides salts of organogermanium compounds expressed by the following Formual (a): ##STR1## (wherein M denotes an oxygen or sulfur atom; and R.sub.1, R.sub.2, R.sub.3, and R.sub.4 may be the same or different from each other and each denotes a hydrogen atom, a lower alkyl group, or an aryl group) with compounds having basic groups, and medicines containing the salts such as biological response modifiers and antitumor agents.
Abstract: Wound healing dressings are prepared by flocculating fibronectin, a biologically active fragment or an analog thereof to produce a water-swellable gel. The gels, in the form of sheets, strips, wedges, strands or I-shaped cross-sections, are especially useful in promoting the healing of corneal, scleral dermal, incisional wounds or lesions. They can be used to enhance the results obtained in keratorefractive surgeries and the healing scleral incision for intraocular surgery.
Abstract: Inflammation, acute and/or chronic, is treated with a CIF (TGF-beta). The CIF may be administered locally or systemically, depending upon the indication, and does not require coadministration of activator or cofactor for efficacy.

Abstract: Growth hormone releasing factor (GRF) preparation which is excellent in stablity by having human serum albumin or glycine incorporated therein, with or without buffer. An amount of human serum albumin or glycine contained is usually 100 .mu.g to 30 mg per 100 .mu.g GRF. The preparation may be in the solid or solution form, preferably in the lyophilized form. An amount of buffer, if added, is preferably enough so that pH of the preparation is kept at 2-7. More preference is that the preparation is kept in nitrogen gas atmosphere. The lyophilized preparation is readily usable for, for example, injection.
