Using two methods (continuous monotherapy and intermittent therapy) for the treatment of psoriasis with cyclosporine, we observed the clinical efficacy and adverse reactions of each treatment method for more than 36 months to evaluate the clinical usefulness of both methods. Thirty-seven cases were analyzed and the following results were obtained: 1) The PASI score evaluated at each visit was maintained between 5 and 10 by both treatment methods and the improvement rate was more than 70%, while there was no difference in the daily dose between the two treatment methods; 2) The period required to achieve remission tended to be prolonged by intermittent therapy, while no change was observed with continuous monotherapy; 3) The period up to relapse tended to become shorter with both treatment methods but this tendency was more marked with intermittent therapy; 4) E-PAP(evaluation for prognosis with averaged PASI) was lower in the continuous monotherapy group and the patients were more satisfied; 5) The incidence of adverse reactions was similar to that reported in previous studies, with no difference between the two treatment methods in this regard; 6) A significant increase in BUN levels was observed in elderly patients; 7) There were only three cases in which the drug was discontinued due to exacerbation and adverse reactions. Based on the above findings, continuous monotherapy seems to be of greater clinical usefulness than intermittent therapy.

[Changes in hemodynamics and catecholamines during single-level exercise at the anaerobic threshold and 120% of the anaerobic threshold in normal subjects].

Exercise training usually involves the sustained performance of exercise at a prescribed intensity. The effects of exercise performed at the anaerobic threshold (AT) have been widely studied. The effects of single-level exercise on catecholamines and cardiac function were assessed at the AT, and at 120% of the AT in eight healthy Japanese men (mean age 21.9 +/- 1.8 years). 1) Symptom-limited exercise testing utilized the ramp protocol with a bicycle ergometer (20 watts/min) for measuring AT and peak oxygen uptake (peak VO2). 2) Exercise testing was repeated on another day, following the same protocol, with blood sampled to measure norepinephrine (NE) and epinephrine (E) in the resting control state and at the AT and peak exercise. 3) Single-level exercise testing at the AT and at 120% of AT utilized the bicycle ergometer on yet another day. Blood for measurement of NE and E was drawn at 3 and 7 min after achieving a steady-state condition. In addition, the cardiac index (CI) and stroke index (SI) were measured by the CO2 rebreathing method. (1) Mean AT and peak VO2 were 18.3 +/- 1.3 and 40.2 +/- 3.0 ml/min/g, respectively. (2) NE and E measured during ramp exercise testing increased rapidly when the intensity of exercise exceeded the AT. NE measured after 3 and 7 min at the AT during single-level exercise equalled 94.7% and 94.5% of the NE value measured at the AT of ramp exercise, respectively. NE measured after 3 and 7 min at 120% of the AT during single-level exercise was 124.7% and 144.7% at the AT of ramp exercise, respectively.(ABSTRACT TRUNCATED AT 250 WORDS)
