摘要:
Resorbable lactide polymer thin membranes are disclosed. The thin membranes are constructed of polylactide resorbable polymers, which are engineered to be absorbed into the body relatively slowly over time in order to reduce potential negative side effects. The membranes are formed to have very thin thicknesses, for example, thicknesses between about 0.010 mm and about 0.300 mm. The membranes can be extruded from polylactide polymers having a relatively high viscosity property, can be preshaped with relatively thick portions, and can be stored in sterile packages.

Sterilized povidone-iodine (polyvinylpyrrolidone-iodine) in an ointment form is obtained by preparation of a mixture of purified water, povidone-iodine, a non-ionic gelling agent, and a non-ionic low suds surfactant. The ointment is a liquid in the temperature range of about 2.degree. C. to 9.degree. C. because of the influence of the non-ionic gelling agent. At room temperature, the mixture forms a free standing ointment which can be sterilized by gamma radiation without degradation of its antimicrobial efficacy, viscosity or shelf life. The ointment is easily prepared by using chilled purified water which maintains the mixture as a liquid while all of the ingredients are mixed together. At room temperature the mixture becomes a free standing ointment.
摘要:
The present invention relates to a three-dimensional cell and tissue culture system. In particular, it relates to this culture system for the long term culture of liver cells and tissues in vitro in an environment that more closely approximates that found in vivo. The culture system described herein provides for proliferation and appropriate liver cell maturation to form structures analogous to tissue counterparts in vivo. The resulting liver tissues survive for prolonged periods, perform liver-specific functions, and maintain hepatic tissue architecture following in vivo implantation. The liver cultures have a variety of applications ranging from transplantation or implantation in vivo, to screening cytotoxic compounds and pharmaceutical compounds in vitro, to the production of biologically active molecules in "bioreactors" and to the construction of extracorporeal liver assist device.

The invention relates to a metallic implant, which has vitreous-crystalline bioactive material on the surface thereof. According to the invention, a metallic implant base body arranged on the surface of the particles has a bioactive, vitreous-crystalline material consisting of 15-45 wt. % CaO, 40-45 wt. % P2O5, 10-40 wt. % ZrO2 and 0.7-3.5 wt. % fluoride, having apatite and calcium zirconium phosphate as main crystalline and a glass phase as an auxiliary component. Said vitreous crystalline material contains at least 35 wt. % main crystal phases and at least 5-15 wt. % auxiliary compounds. All of the percentage data is expressed in relation to the total weight of the vitreous crystalline material and the particle size of the vitreous crystalline material is between 60-350 μm.

摘要:
Disclosed is a preparation-at-use device comprising: (1) a pre-formed hydrogel component packaged in a first compartment; the pre-formed hydrogel component comprising a gelling agent and a solvent; and (2) a benefit component packaged in a second compartment; the benefit component comprising at least one compound that is unstable when contacted with the pre-formed hydrogel component; wherein the first and second compartments are separately packaged prior to use, and wherein the device comprises means for contacting the pre-formed hydrogel component and benefit component upon use.
摘要:
An object of the present invention is to provide a protein useful as a sphingomyelin detecting probe, which specifically recognizes sphingomyelin and has low cytotoxicity. The present invention provides a protein which has an amino acid sequence having, as the amino acid sequence from the 1st to the 48th amino acid, the amino acid sequence from the 1st to the 48th amino acid in Lysenin 1, and as the amino acid sequence from the 49th to the 298th amino acid, the amino acid sequence from the 51st to the 300th amino acid in Lysenin 3; and a protein which is obtained by deleting N terminal and/or C terminal from earthworm toxins Lysenin 1 or 3, and which specifically recognizes sphingomyelin.
