Abstract: Certain 2-oxindole-1-carboxamide compounds having an acyl substituent at the 3-position, and also on the carboxamide nitrogen atom, are inhibitors of the cyclooxygenase (CO) and lipoxygenase (LO) enzymes, and are useful as analgesic agents and anti-inflammatory agents in mammalian subjects. These 2-oxindole-1-carboxamide compounds are of particular value for acute administration for ameliorating pain in human patients recovering from surgery or trauma, and also for chronic administration to human subjects for alleviating the symptoms of chronic diseases, such as rheumatoid arthritis and osteoarthritis. Certain 2-oxindole-1-carboxamide compounds unsubstituted at C-3, but having an acyl substituent on the carboxamide nitrogen atom, are useful as intermediates to the aforementioned analgesic and anti-inflammatory agents.

Abstract: An improved intraintestinal bypass graft for attachment in the lumen of a resectioned intestine or duct upstream of the anastomosis site in order to protect the healing anastomosis comprises an elongated tube formed of a thin, highly flexible, water-impervious wall material terminating at its distal end in a short, reduced diameter nipple. The surgical procedure for implanting the bypass graft can be simplified and shortened in time by readily fitting the distal nipple over one end of an elongated pliable leader, or alternatively over the terminal anvil nut of a circular anastomosis surgical stapler, and then drawing the leader or stapler body through the patient's anus to pull the distal end of the bypass graft out of the anus. The need to tie the distal end of the bypass graft to the leader or surgical stapler is eliminated.

Abstract: An improved process for preparing (4S)-6-fluoro-spiro-[chroman-4,4'-imidazolidine]-2',5'-dione (sorbinil) or its (2R)-methyl derivative (2-methylsorbinil) is disclosed herein, starting from p-fluorophenol in each instance. The final products obtained have known pharmaceutical value as agents for the control of certain chronic diabetic complications. Key steps concerned with the process involve converting p-fluorophenol into the appropriate .beta.-(4-fluorophenoxy)alkane halide, followed by amidoalkylation with N-benzoyl or N-(lower alkanoyl)-.alpha.-hydroxyglycine to form an intermediate 2-amidoalkylated derivative thereof, and then dehydration and spiroalkylation of said intermediate by treatment with a dehydrating agent and a base to yield a spiroalkylated azlactone compound.

Abstract: A fluid drainage system includes a suction chamber and a collection chamber. The suction chamber includes a suction regulator comprised of first and second chambers separated by a divider. An opening in the divider has a biased closing member associated therewith for opening or closing the opening according to the pressure differential between the chambers. A dash pot is connected to the closing member for damping the force on the closing member. The drainage system further includes devices for measuring the patient airflow, patient negativity and imposed suction. Those devices consist of diaphragms having dials connected thereto such that movement of the diaphragm results in movement of the dial and thereby indicating a change in one of the above noted variables. As an alternative, the drainage system includes a venturi meter for measuring airflow. Finally, the system contains an anti-spill device that prevents the spilling of fluids from the collection chamber to other chambers in the device.

Abstract: A process for the preparation of penicillanic acid 1,1-dioxide and esters thereof readily hydrolyzable in vivo, which comprises oxidation of a 6,6-dihalopenicillanic acid, or an ester thereof readily hydrolyzable in vivo, to the corresponding 6,6-dihalopenicillanic acid 1,1-dioxide or ester thereof, followed by dehalogenation (e.g. by hydrogenolysis).

Abstract: A device for affixing a pretensioned ligament or tendon prosthesis to a bone of a patient includes a hollow elongated sleeve adapted to fit within a through drill hole in the bone and a cooperating wedge. A portion of the bore of the hollow sleeve is tapered with decreasing bore cross-sectional thickness towards the front end of the elongated sleeve. Th wedge is shaped so that a portion of a ligament or tendon prosthesis can be securely trapped between the wedge and the inner wall of the sleeve when the wedge is fully advanced forwardly within the sleeve. The device also includes a locking nut or ferrule for releasably locking the sleeve and wedge together with the wedge fully advanced within the sleeve, and a releasable bolt/washer assembly for preventing the prosthesis from being pulled forwardly through the drill hole in the patient's bone. The device is easy to use and provides a highly secure fixation of the pretensioned prosthesis.
