摘要:
The present invention provides an S-nitroso group-containing albumin, comprising an S-nitroso group introduced to at least one lysine in the amino acid sequence for albumin. The S-nitro group has been introduced into a lysine in the S-nitroso group-containing albumin of the invention to allow more S-nitroso groups to be included in the albumin, thus ensuring more potent inhibition of cancer cells in NO groups.
摘要:
A basis particle comprises a basic or acidic basis particle coated by a water-insoluble coating film, wherein the water-insoluble coating film contains a substance that is acidic with respect to the basic basis or basic with respect to the acidic basis. According to the basis particles (i.e., a main ingredient or an active drug)of the present invention, it is possible to temporarily adjust pH occurring in the immediate proximity of the basis particles by using a coating film, elution of the basis particles is suppressed and superior elution is exhibited without dependence on bodily pH. It is also possible to mask tastes such as the bitterness of the basis and it is possible to ingest drugs without sensing any bitterness.

An oral solid preparation including a base compound and a powdery or granular additive colored with a colorant and a method of manufacturing an oral solid preparation including the steps of: coloring an additive with a colorant, mixing the resultant additive with a base compound, and tableting the mixture.
摘要:
An oxygen-carrying blood substitute preparation stable upon storage is provided. The preparation comprises an oxygen-carrying substance capable of reversibly binding and releasing oxygen in vivo and an amount of a physiologically tolerable reducing agent effective for preventing at least partially irreversible oxidation of said oxygen-carrying substance. Preferably the oxygen-carrying substance is a hemoglobin-based substance in the form of a liposome encapsulating hemoglobin.
摘要:
The present invention provides a method of producing a complex of albumin and a deoxy form metal complex having a porphyrin structure, which includes mixing albumin and a metal complex having a porphyrin structure under a gas atmosphere substantially free of carbon monoxide and oxygen, as a method of producing an artificial oxygen carrier containing a complex of albumin and a metal complex having a porphyrin structure, under a deoxidation (nitrogen, other inert gases) atmosphere without using carbon monoxide.
摘要:
A recombinant protein is provided containing a serum albumin multimer wherein at least two genes encoding serum albumin are combined with each other by gene recombinant technology and incorporated into a host cell for the effective production of the protein. The gene encoding a human serum albumin multimer and the recombinant vector are also provided. The protein is used as a safe drug administration carrier that is capable of extending the half life of a drug in the blood without the risk of contamination of viruses and so on, as compared with a conventional drug administration carrier.
摘要:
To provide a plastic vessel containing an albumin preparation which completely restrains formation of thermally denatured albumin, a plastic molded member in a cylindrical shape is extruded in a molten state into opened dies, one end of which is closed in the dies, and a vessel is molded by blowing a compressed gas into the molded member in the dies or by bringing inner portions of the dies into a vacuum state. While the vessel is still disposed in the dies, an albumin preparation is introduced from an opening portion into an inner portion of the vessel and, therefore, the albumin preparation can be filled into the vessel in a sterilized state without being brought into contact with the atmosphere. Then, an opening portion of the vessel filled with the albumin preparation is hermetically sealed at an internal temperature of the opening portion of about 40 to 70° C. Thus formation of thermally denatured albumin can be completely restrained.
