摘要:
A process for the preparation of a light-sensitive silver halide photographic material comprising a support, a silver halide emulsion layer, and a non-light-sensitive hydrophilic colloid layer which consists essentially of a plurality of layer elements; a process comprises incorporating oil particles into at least one of the elements, so that the oil particle density of the outermost layer element is not the highest of the oil particle densities of all of the elements.
摘要:
A copolymer of lactic acid and glycolic acid which has a weight-average molecular weight of not less than about 5000 and a dispersity of about 1.5 to 2 is advantageously used as a biodegradable polymer for medical preparation.
摘要:
Disclosure herein is novel oxalic acid ester derivatives represented by the general formula: ##STR1## wherein either one of X and Y represents a nitro group, and the other represents ##STR2## in which R represents a lower alkyl group, and n represents a figure of 1-50. The oxalic acid ester derivatives are useful as chemiluminescent reagents for fluororescent substances.
摘要:
Novel 1(2H)-isoquinolone compounds and the acid addition salts thereof are disclosed. These compounds are useful as pharmaceutical agents in view of their anti-ulcer, stomach mucous membrane blood flow increasing, anti-hypertensive, analgesic, anti-histamine, anti-cholinergic and gastric secretion inhibitory activities.
摘要:
Novel derivatives of glyoxal-2-oxim represented by the chemical formula ##STR1## wherein R is hydrogen or a lower alkyl or phenyl group, are provided in accordance with the present invention. These derivatives are prepared by reacting the corresponding isoxazole-5-carbaldehyde with nitromethane in the presence of a metal alkoxide, or the corresponding 5-acetylisoxazole with a nitrite. They have anti-inflammatory and/or analgesic activities.
