Abstract: A product and method of treating tissue particularly during the embalming process. The product is produced by drying and finely grinding plants from the Plantain family to a powder. The method involves applying the powder to wounds, incisions and the like to form closure.

Abstract: A method of making animal specimen, of which the processing steps include a dead animal as a specimen body to be directly soaked in a 3-in-one mixed liquid for a given period of time; the 3-in-one mixed liquid comprises granular boric acid, NaCl, phenol, a liquid of formaldehyde solution, and a volatile alcohol. A specimen body soaked with such a mixed liquid has an excellent antiseptic result without removing the muscles, bones and internal organs of a specimen body, but a specimen body can be dried and made simply.

Abstract: A skin preparation such as skin lotion or cream which is resistant to being removed when the skin is washed includes a skin-preparation base and a plurality of wash-off-resistance substantivity agents. The wash-off-resistance substantivity agents include a polymeric skin-feel-modifying compound, a quanternary ammonium compound, a hydrophobic modified starch, a substantive silicone and a substantive emollient.

Abstract: A mercury and formaldehyde free histological fixative. The fixative employs standard non-toxic components comprising one or more alkanols, one or more diols and triols such as ethylene glycol, and one or more acids such as acetic and formic acid in an aqueous solution. A salt of a metal ion having an oxidation state of at least two may be added as an optional mordant. Osmotically active substances such as sodium chloride may be used as an option as desired to control osmotically induced cell volume changes.

Abstract: The invention relates to a press cylinder for a high-temperature, high-pressure pressing machine for use in sinter molding ceramics, hard metals, and the like. An outer casing constructed of a carbon fiber reinforced carbon composite and an inner casing constructed of a heat resistant material are fitted together. The inner casing is formed with a longitudinally extending slit which meets given conditions. A gap which meets given conditions is formed between the outer casing and the inner casing. Because of the presence of the slit and the gap, no substantial stress is liable to be exerted on the outer and inner casings which are different in thermal expansion coefficient. Therefore, the outer and inner casing are not liable to fracture or plastic deformation.

Abstract: An ocular insert and an ocular composition are disclosed. The insert and the composition comprises a steroid in two different forms.

Abstract: Extended-life aqueous tissue fixative compositions or solutions are provided for use in histopathology work and the like. The compositions include glutaraldehyde at controlled pH, a boric acidtetraborate buffer, buffer stabilizer and complexing agent. The compositions, which also may include a compatible surfactant, and their method of application enable efficient fixing such that the treated tissues have low artifactual color and good texture and may readily be sectioned and accurately stained.

Abstract: A liquid biocidal agent that has bacteriostatic and viricidal activities is described. The composition includes about 100 to 400 parts per million sodium polypectate, about 13 to 250 parts per million silver ion, about 4 to 8% glycerine, sufficient base such as ammonium hydroxide to maintain a pH in the range of from about 7.2 to 7.8, and distilled water. The composition is useful for treating Herpes virus, condyloma, and for preventing Staphylococcus aures infection.

Abstract: A liquid cleaner, lubricant and topical biocidal agent that is useful with hard water and has bacteriostatic activities is described. The composition includes lauryl diethanolamide, propylene glycol, glycerine, sodium polypectate, a water soluble detergent which is non-deleteriously reflective with sodium polypectate, silver ion, sufficient base such as ammonium hydroxide to maintain a pH in the range of from about 7.2 to 7.8, and distilled water. The composition is useful for treating herpes virus, condyloma, and for preventing Staphylcoccus aureus infection, and as a lubricant to be used during delivery at the time of birth.

Abstract: The present invention relates to a method for embalming the body of a deceased human being, and to materials for use therein. More specifically, the invention provides a method in which a composition comprising certain specified quaternary ammonium compounds is applied to the skin of the body for the purposes of preventing decay, preventing the growth and spread of disease-causing organisms and retaining life-like appearance.

Abstract: A liquid cleaner, lubricant and topical biocidal agent that is useful with head water and has bacteriostatic activities is described. The composition includes lauryl diethanolamide, propylene glycol, glycerine, sodium polypectate, a water soluble detergent which is non-deleteriously reflective with sodium polypectate, silver ion, sufficient base such as ammonium hydroxide to maintan a pH in the range of from about 7.2 to 7.8, and distilled water. The composition is useful for treating herpes virus, condyloma, and for preventing Staphylcoccus aureus infection, and as a lubricant to be used during delivery at the time of birth.

Abstract: A method is provided for preparing specimens of water containing micro-organisms, for microscopic viewing, employing a composition for immobilizing and also for staining the micro-organisms as an aqueous solution. The composition contains hydrofluoric acid and, advantageously, a small amount of malachite green dye.

Abstract: This specification describes a complex of osmium tetroxide and a compound having a heterocyclic ring containing one or two tertiary nitrogen atoms. The compound may be an aromatic tertiary amine and the tertiary nitrogen atom may be the sole heterocyclic atom in the heterocyclic ring. The complexes described are suitable for fixing and staining cells and may be used in the preparation of biological specimens for examination by electron microscopy.

Abstract: A double aldehyde treatment process of erythrocytes is disclosed. Erythrocytes from various sources can be treated in a two-step process to render them stable and subsequently useful in antigen antibody detection systems. Glyoxal is used as a first treating medium followed by a second treatment step using formaldehyde or glyoxal as the fixative. Glyoxal is used in the first step in amounts ranging from 0.1 to 0.4 gm. per 0.8 ml. of Packed Cell Volume of erythrocytes, followed by the second treatment step in which at least 0.1 gm. of formaldehyde or glyoxal and preferably 0.1 to 0.6 gm. per 0.8 ml. Packed Cell Volume of treated erythrocytes is used. The reaction medium is preferably aqueous hypertonic and most preferably a sodium citrate medium. The treated cells can be used in detection of hepatitis associated antigen in a reverse passive hemagglutination test.

Abstract: A composition and process for the preservation of biological specimens in which specimens are immersed in a preservative obtained from a starch glycerite solution that has been slowly heated to a temperature above 130.degree. C. to achieve a long-range, non-toxic preservative in which the natural color of a marine specimen can be preserved indefinitely.

Abstract: A superior and extremely rapid histological staining method is described in which frozen tissue is briefly immersed in an aqueous solution comprising trichloroacetic acid, zinc chloride and formaldehyde and then in a second solution comprising hematoxylin. The tissue can be further counterstained if desired. Also disclosed are improved fixatives useful in this and other histological techniques.

Abstract: Stable preparations of sensitized erythrocytes are provided by simultaneously admixing washed erythrocytes in a buffered aqueous solution of glutaraldehyde, antigen or antigen-protein conjugate and formaldehyde. After washing, the separated sensitized erythrocytes can be lyophilized and thereby become stable at room temperature.
