Tinidazole is included as a second antimicrobial agent in effective, antimicrobial amounts not greater than 1.0 micrograms/ml. Nile Blue A is also included in Gardnerella Vaginalis inhibiting concentrations.

Abstract: A method for assaying the fertilization potential of a mammalian ovum that has been removed from an ovarian follicle, together with a portion of accompanying follicular fluid. The method includes the step of measuring the concentration of at least one selected glycosaminoglycan in the follicular fluid accompanying the ovum to be tested. That concentration is then compared with concentrations of the same glycosaminoglycan characteristic of the follicular fluid of atretic and non-atretic follicles.

Abstract: A method for evaluating the fertility of a male mammal. A semen sample is obtained from the individual to be tested. The sperm is separated from the seminal plasma of the semen sample. At least one test portion and a control portion of the sperm are isolated. The sperm portions are incubated, the test portion being exposed to a glycosaminoglycan in a concentration effective to induce an acrosome reaction in sperm. A representative sample of incubated sperm from each portion is then counted by means of observation by light microscopy to measure the increase in acrosome reaction in the test portions as compared to the control portion. A kit is provided for the convenient performance of the method. The kit includes a supply of sterile liquid culture medium, sterile closable culture vessels, and a supply of selected, sterile GAG meterable substantially aseptically in known amounts into each culture vessel used as a test vessel.

Abstract: A method for preparation of multimeric fibronectin. Dimeric fibronectin is treated with guanidine. The dimeric fibronectin so treated is then incubated to allow multimeric fibronectin to form therefrom.

Abstract: A method for evaluating the fertility of a test male mammal relative to the fertility of a control male mammal. The method includes the steps of collecting samples of semen from the test male and the control male. The binding affinity of a selected glycosaminoglycan to the sperm of the semen samples is measured by a selected means for measuring binding affinities. The fertility of the test male may be evaluated as higher or lower than that of the control male by the degree to which the binding affinity of the glycosaminoglycan to its sperm is higher or lower than the binding affinity of the glycosaminoglycan to the sperm of the control male.

Abstract: A method for reclaiming gold in metallic form from gold-containing scrap, including gold-containing base metal alloys and articles in which base metals are at least partially covered with a layer of gold. The method includes the steps of exposing the gold-containing scrap under an inert atmosphere to a leaching solution. The leaching solution has dissolved therein an oxidizing agent including metal ions capable of assuming at least two oxidation states, a portion of the metal ions being in the higher of the two oxidation states. The leaching solution also contains a complexing agent including halide ions in aqueous solution. By so exposing the gold-containing scrap to the leaching solution, base metal contained therein is dissolved to leave a solid metallic residue enriched in gold. The solid metallic residue then is collected mechanically.

Abstract: A vertebral clamp adapted to control the spatial relationship between two vertebrae by attachment to the laminae thereof. The vertebral clamp includes a longitudinally extending body divided into first and second halves. The halves are fastened together by fastening means that allow for adjustment of the length of the body. Two laminar clamps are attached to the body, one at each end thereof. Each laminar clamp is adapted to rigidly and securely clamp from opposed sides to a lamina of one of the vertebrae with the other laminar clamp similarly clamped to a lamina of the other vertebra.

Abstract: A monoclonal antibody produced by a hybridoma formed by the fusion of cells from a mouse myeloma line and spleen cells from a mouse previously immunized with thrombospondin. The monoclonal antibody reacts with human, bovine, and canine thrombospondin but not with the thrombospondin present in rabbit serum. The monoclonal antibody is capable of being used to identify human, bovine, and canine thrombospondin in ELISAs and by means of immunohistological techniques and also can be used to isolate such thrombospondin by when employed in immunoisolation techniques.

Abstract: A method for cross-linking organopolysilane polymers. The method includes the steps of mixing an organopolysilane with a cross-linking agent to make a reaction mixture. The cross-linking agent includes molecules having at least two carbon-carbon double bonds and a ratio of such bonds to the molecular weight of the molecule of at least 1:150. Radical formation is then induced in the organopolysilane of the reaction mixture to cause formation of a reaction product including cross-linked organopolysilane polymers.

Abstract: An injectable pharmaceutical preparation for the induction of multiple follicular growth in mammals. A superovulation inducing hormone selected from the group consisting of follicle stimulating hormone and pregnant mare serum gonadotropin in aqueous solution is encapsulated within liposomes. The liposomes have the following characteristics: when encapsulating the hormone and injected into cows five days prior to estrus, the liposomes produce multiple follicular development as monitorable by rectal palpation of the ovaries.

Abstract: A method for preparing a monoclonal antibody of improved cross-species specificity. The method includes the steps of preparing an inoculum antigen from a first species of animal producing the antigen and then immunizing a selected subject animal with the inoculum antigen. The method further includes the steps of fusing spleen cells from the immunized subject animal with myeloma cells to produce hybridomas. A test antigen is prepared corresponding to the inoculum antigen but derived from a second species of animal, distinct from the first species of animal from which the inoculum antigen was prepared. Hybridomas are screened for desired antibody production against the test antigen. The hybridoma producing antibodies most active against the test antigen is then cultured, and monoclonal antibodies are produced therefrom.

Abstract: A naso-gastric feeding device is disclosed which includes a highly flexible feeding tube carried inside of a semi-flexible guide tube. The guide tube is inserted into the patient and then fluid is forced through the guide tube into the patient carrying with it the feeding tube. The guide tube is then withdrawn so that only the feeding tube is left in the patient with feeding taking place therethrough.
