Angiotensin converting enzyme (ACE) and interleukin 1 activities were assayed simultaneously in the serum free medium from the unstimulated peripheral blood monocytes from 32 patients with rheumatoid arthritis (RA), 11 patients with osteoarthritis, and 25 normal controls matched for age and sex. Angiotensin converting enzyme activity was raised in most(More)
BACKGROUND The anti-human Fas/APO-1/CD95 (Fas) mouse/human chimeric monoclonal IgM antibody ARG098 (ARG098) targets the human Fas molecule. The cytotoxic effects of ARG098 on cells isolated from RA patients, on normal cells in vitro, and on RA synovial tissue and cartilage in vivo using implanted rheumatoid tissues in an SCID mouse model (SCID-HuRAg) were(More)
We examined the analgesic effect of the selective kappa opioid receptor agonist SA14867 and the balance of its antinociceptive and sedative effects. The ED(50) values of SA14867 after oral administration for acetic acid-induced writhing, first and second phases of the formalin test, and rotarod test in mice were 6.1, 9.3, 2.7, and 19.5mg/kg, respectively.(More)
SA14867 ((+)-3-Acetyl-6-chloro-2-[2-(3-(N-(2-ethoxyethyl)-N-isopropylamino)propoxy)-5-methoxyphenyl]benzothiazoline O,O'-diacetyl-L-tartrate), a selective kappa-opioid receptor agonist, was synthesized and its antinociceptive and antipruritic effects were investigated. In a functional binding assay, SA14867 showed approximately more than 31,000 and 2200(More)
Keyhole lympet hemocyanin (KLH)-specific suppressor T (Ts) cells that suppress the in vitro secondary anti-trinitrophenyl (TNP) PFC response to TNP-KLH could be induced when murine spleen cells were precultured with KLH. N-(2-carboxyphenyl)-4-chloroanthranilic acid disodium salt (CCA) at 1-100 micrograms/ml augmented the in vitro induction of Ts cells when(More)
