摘要:
A method for determining human prolyl hydroxylase by radioimmunoassay according to the sandwich method wherein a monoclonal antibody to human prolyl hydroxylase and polyclonal antibody to human prolyl hydroxylase are used, characterized in that a monoclonal antibody to human prolyl hydroxylase is used as at least one of the antibodies which are to be coated on a solid support and to be labeled with a radioactive element. This method is simple and operable with small amounts of samples and gives exact results. Thus, this method is useful for the diagnosis of hepatic diseases. A monoclonal antibody specific to the .beta.-subunit of human prolyl hydroxylase is used to test for the human prolyl hydroxylase.

Disclosed herein are a derivative of dihydroxybenzamide represented by the formula(I): ##STR1## wherein (1) R.sup.1 represents a hydrogen atom or a lower alkyl group and R.sup.2 represents a straight chain-alkyl group of 4 to 12 carbon atoms, a branched chain-alkyl group of 4 to 12 carbon atoms, a cyclo-alkyl group of 4 to 12 carbon atoms, ##STR2## wherein n is an integer of 1 to 6, or a pyridyl group which is substituted or unsubstituted, or (2) R.sup.1 and R.sup.2 are cyclized to make a heterocycle containing amino group represented by the formula ##STR3## wherein X represents a nitrogen atom or a methine and Y represents a hydrogen atom, an alkyl group of 1 to 6 carbon atoms or a phenyl group, and a pharmaceutical composition containing the same.
摘要:
In the thermal cracking of a heavy petroleum oil (having an API specific gravity of not more than 25) in a tubular type heating furnace, possible occurrence of coking trouble inside the furnace can be prevented by applying a magnetic field of fixed magnitude transversely to the flow of the heavy petroleum oil being introduced into the furnace or by applying a fixed magnitude of magnetic field transversely and, at the same time, applying a fixed magnitude of direct-current voltage parallel to the flow of the heavy petroleum oil being introduced into the furnace. More effective prevention of occurrence of coking can be obtained by having a specific inorganic substance incorporated in the heavy petroleum oil before the oil is subjected to the magnetic field or to simultaneous application of the magnetic field and voltage.
