Abstract: A method for moving a probe (10, 91) through a cell material (20), which is formed from biological cells (21), is described, the probe (10) displacing the cells (21) without injury. A probe (10, 91) for performing the method and a cell manipulator, which is equipped with at least one probe of this type, are also described.

Abstract: The pharmaceutical formulation in the form of an effervescent and/or disintegrating tablet or of instant granules contains at least one active ingredient having an irritating taste and at least one matrix which delays the release of the active ingredient and is present as an intimate mixture with the active ingredient particles or covers said particles and is applied to a carrier. The formulation releases at most 65%, preferably at most 50%, of the active ingredient in aqueous solution at room temperature within about 2 min but more than 70%, preferably at least 80%, of the active ingredient within max. 20 min, preferably max. 15 min, in 0.1N HCl at 38.degree. C. The matrix preferably contains at least one fatty ester and/or one wax, preferably having a melting point between 30.degree. and 45.degree. C., in particular between 32.degree. and 35.degree. C., and/or at least one cellulose derivative and/or at least one polymethacrylate.

Abstract: The invention relates to a relatively pure pulverulent mannitol, having a moderate and not excessive friability of between 40 and 80% in a Test I, a low apparent density of between 300 and 525 g/l for a particle size cut of between 100 and 200 microns and, additionally, a specific particle size in the sense that it contains less than 30% of particles with a size of less than 75 microns. This pulverulent mannitol possesses remarkable functional properties which make its use particularly recommended as sweetening agent, texturizing agent or additive excipient or vehicle in the food and pharmaceutical industries.

Abstract: An insect repellent having extended repellency consists of d-limonene, di-N-propyl isocinchomeronate, N-octyl bicycloheptene dicarboximide, C-11 alcohol ethoxylate, polysorbate 80, and an organic solvent selected from the group consisting of dipropylene glycol N-butyl ether, citronella oil, dimethyl phthalate, and N,N-diethyl-m-toluamide, and mixtures thereof.

Abstract: Stable, comfortable, preserved, topical, ophthalmic compositions of acidic drugs are disclosed. Methods for their use are also disclosed.

Abstract: A solid pesticide composition such as a bait or granule which is made water resistant by coating the solid pesticide with a hydrophobic fatty acid poly ester of sucrose, sorbitol, sorbinose, glycerol and/or raffinose. The coated solid pesticide composition retains its palatability to the target pest.

Abstract: The present invention relates to a microencapsulated chlorpyrifos or endosulfan composition comprising a polyurea shell and one or more photostable ultraviolet and visible light absorbent compound having a log molar extinction coefficient of from about 2 to 5 with respect to radiation having wave lengths in the range of about 310 to 450 nanometers, wherein said photostable ultraviolet and visible light absorbent compound does not react with the monomer used in building the polyurea shell. The result is a microencapsulated composition having unexpected long, extended insecticidal activity with high toxicity to target species and very low toxicity to non-target animals.

Abstract: A method and compositions for reducing the itch associated with the bite of a blood-feeding insect such as a mosquito or black fly are disclosed. The method entails applying a topical pharmaceutical formulation of papain, pancreatin or subtilisin, optionally including urea, to the skin proximate to the bite. Compositions are provided in the form of solutions, lotions, ointments and salves containing papain, pancreatin or subtilisin and, optionally, urea.

Abstract: The present invention is directed to an active agent dosage form which is useful for the prolonged delivery of an active agent formulation to a fluid environment of use. The active agent dosage form is a matrix that has on its surface two or more insoluble bands. The invention is also directed to the method for making the active agent dosage form.

Abstract: A phenolic, cesium-specific, cation exchange resin is prepared by neutralizing resorcinol with potassium hydroxide, condensing/polymerizing the resulting intermediate with formaldehyde, heat-curing the resulting polymer to effect cross-linking and grinding it to desired particle size for use. This resin will selectively and efficiently adsorb cesium ions in the presence of a high concentration of sodium ions with a low carbon to cesium ratio.

Abstract: Macromolecular conjugates of a synthetic polypeptide having influenza virus antigenic properties are disclosed. These conjugates contain a polypeptide corresponding substantially to the 215-235 region of the matrix protein (M-protein) of influenza virus.
