摘要:
A method of combating bacterial infections in humans involves the administration of an antibacterially effective amount of a compound of the formula: ##STR1## wherein R is phenyl or thienyl group, and R' is a group which constitutes together with the adjacent nitrogen atom a pyridinium group that is unsubstituted or substituted by carbamoyl, or a 4'-methyl-5'-(.beta.-hydroxyethyl)-thiazolium or a pharmaceutically acceptable salt thereof, to a patient. This method is effective particularly against Pseudomonas aeruginosa as well as against other Gram negative and positive microorganisms.
摘要:
Novel cephalosporins of the formula, ##STR1## wherein R is a hydrogen atom or an alkyl, aryl or thienyl group, and R' is a group which constitutes together with the adjacent nitrogen atom a 5- or 6-membered ring containing 1 or 2 nitrogen atoms, which are effective particularly against Pseudomonas aeruginosa as well as against other Gram negative and positive microorganisms, for example, N-[7-(.alpha.-sulfophenylacetamido)ceph-3-em-3-ylmethyl] pyridinium 4-carboxylate, N-[7-(.alpha.-sulfo-3'-thienylacetamido)ceph-3-em-3-ylmethyl] pyridinium-4-carboxylate, and their pharmaceutically acceptable salts thereof. Sodium salt of the former is prepared by, e.g. reacting sodium 7-(.alpha.-sulfophenylacetamido) cephalosporanate with pyridine in water.

N.sup.1 -(2-tetrahydrofuryl)-5-fluorouracil is produced in high yield by reacting 5-fluorouracil with 2,3-dihydrofuran in the presence of trimethylsilyl chloride and a tertiary amine and treating the resultant mixture with an aqueous alkaline solution.
摘要:
A new and industrially useful method of producing 1(or 1,3-bis)-(tetrahydro-2-furyl)-5-fluorouracil or a mixture thereof by reacting 5-fluorouracil with 2,3-dihydrofuran at elevated temperature in a closed vessel. Depending upon reaction conditions, each of the above 5-fluorouracil derivatives or a mixture of them is produced.1,3-Bis-(tetrahydro-2-furyl)-5-fluorouracil thus formed can be converted to 1-(tetrahydro-2-furyl)-5-fluorouracil by solvolysis under non-acidic conditions.

An automatic book binding machine for cut-sheets includes a main body, a belt conveyor mounted on the main body and a feeder mounted on the main body and adapted to feed cut-sheets. A front cover of the cut-sheets has an identification mark for identifying one book from other books. A detection sensor is mounted on the belt conveyor for detecting one end of the cut-sheets. A nozzle mounted on the belt conveyor is controlled by the detection sensor to automatically apply a linear band of glue along one edge of the cut-sheets. A first mark sensor is mounted on the belt conveyor to sense a detectable mark on one of the cut-sheets and control the nozzle to stop applying glue to the cut-sheet. A second mark sensor is mounted on the belt conveyor to sense the detectable mark and control the nozzle to resume application of glue to the cut-sheet. A pressing plate is mounted on the main body for stacking up for storage the cut-sheets onto which the linear band of glue has been applied, aligning the sides of each cut-sheet, and pressing the glue-applied areas of the cut-sheets for each book from the top of the front cover in cooperation with the first and second mark sensors.
