Fifty-seven patients took part in a controlled double-blind trial between tiopronin and D-penicillamine as basic treatment for rheumatoid arthritis. Thirty-nine (19 receiving tiopronin, 20 receiving D-penicillamine) completed the trial after 1 year. Both drugs resulted in a decrease of the erythrocyte sedimentation rate, Ritchie index, and Lee index and in a sparing effect on symptomatic antiinflammatory therapy. Improvement in these variables was statistically highly significant at any interval with tiopronin, but was sometimes less or not at all significant with D-penicillamine. Nevertheless, the difference in effects between the 2 drugs never reached statistical significance. Six patients receiving tiopronin and 6 receiving D-penicillamine were taken out of the experiment because of side effects.

AD, Weinberger R. Use of dynamically coated capillaries for the routine analysis of methamphetamine, amphetamine, MDA, MDMA, MDEA, and cocaine using capillary electrophoresis. J Forensic Sci 2001;46(5):1025-1032.ABSTRACT: A rapid, accurate, precise, reproducible, economical, and environmentally gentle method using capillary electrophoresis (CE) is presented for the routine analysis of methamphetamine, amphetamine, MDA, MDMA, MDEA, and cocaine in seized drugs.The methodology uses a 32 cm by 50 m capillary (length to detector 23.5 cm) with a commercially available buffer kit and diode array UV detection. Dynamic coating of the capillary surface is accomplished by flushing with base for 1 min, a proprietary polycation for 1 min, and then a proprietary polyanion for 2 min. This approach provides a relatively high and stable electroosmotic flow (EOF), even at low pHs. The background electrolyte (BGE) contains 75 mM phosphate buffer (pH 2.5) with the same polyanion as above.Using this methodology, amphetamine, methamphetamine, MDA, MDMA, MDEA, and an internal standard (n-butylamphetamine) are baseline resolved in less than 5 min. The run-to-run migration time %RSDs and peak area %RSDs are typically Ͻ0.3% and Ͻ2.1%, respectively. The day-to-day and capillary-to-capillary migration time %RSDs are Ͻ1.5% and Ͻ2.1%, respectively. The %RSDs of the relative migration times compared with the internal standard on a day-to-day and capillary-to-capillary basis are Ͻ0.2% and Ͻ0.06%, respectively. The linear dynamic range using peak areas range from 0.003 to 0.10 mg/mL. The correlation coefficients are Ͼ0.9998, with all calibration curves passing at or near the origin. Similar data are obtained for cocaine and its internal standard henyltoloxamine.None of the compounds usually encountered in illicit samples interfere with the target compound (e.g., methamphetamine and cocaine) or the internal standard. Quantitative results for synthetic mixtures and seized exhibits are in good agreement with actual val-ues, and also with results obtained from other techniques. The relatively high EOF for the dynamically coated capillary system allows for the screening of basic, acidic, and neutral adulterants in drug seizures; identification is facilitated by the use of automated UV library searches.

In a multi-centre double-blind cross-over trial using the double-placebo technique, 55 patients with rheumatoid arthritis were treated for 10 days for each trial drug with ketoprofen (200 mg/day) and ibuprofen (1200 mg/day). Both drugs induced a clinically and statistically significant improvement of all the symptoms studied, except for pain at night during ibuprofen administration. Ketoprofen displayed a therapeutic efficacy significantly superior to ibuprofen in five of the eight symptoms studied. Side-effects were recorded in 10 patients receiving ketoprofen (one patient withdrew because of heartburn) and in nine patients receiving ibuprofen.
