摘要:
N,N,N-trimethyl-2-hydroxyethyl-ammonium-[1-ethyl-6-fluoro-4-oxo-7-(1-piperazinyl)-1,4-dihydro-quinolizine-3-carboxylate] of the formula I ##STR1## as a norfloxacin antimicrobial salt capable of enteral administration.
摘要:
The present invention concerns a method for improving plant growth characteristics by increasing expression in a plant of a nucleic acid encoding a CCS52 protein and/or by increasing level and/or activity in a plant of a CCS52 protein. The invention also relates to transgenic plants having improved growth characteristics, such as increased plant size, increased organ size or increased number of organs, which plants have increased expression of a nucleic acid encoding a CCS52 protein.

摘要:
A circuit arrangement for determining the characteristics of liquids and/or gases, in particular for determining the diverse parameters of blood. The equipment determines the ratio of the signals of the sensing element resp. of the signal converter at a double-light photometer and a reference, simultaneously performing constant or periodical testing, accordingly, the control of the whole measuring system can be ensured. Signal processing takes place by the expansion of series or cutoff point interpolating logarithm forming, by averaging; the system includes structural elements for performing adjustable error detection. The largest advantage of the circuit arrangement according to the invention lies in that the instabilities of the photometers of traditional construction may be eliminated, a higher measuring accuracy becomes possible, and by ensuring the testing possibilities, by performing a continuous self-control reliable measuring data are delivered.
摘要:
The present invention is concerned with the preparation of chemical intermediates, namely, beta-amino-acrylic acid ester derivatives of nitrogen heterocycles, i.e. pyridine, quinoline, quinoxaline, pyrazine, pyrimidine and the like. Said intermediates are cyclized to form pyrido-pyrimidine type final products possessing analgesic activity.
