The study was controlled by a non-treated field on the volunteers' backs. The main points of interest in this study included the size of the erythema reaction, the capillary blood flow and onset and intensity of itching. With respect to the size of the erythema reaction, both clemastine hydrogen fumarate and isoprenaline proved more effective than placebo in most cases. This superiority was, in some cases, statistically significant. There were no statistically significant differences between the gel preparations for the other parameters investigated. Clemastine hydrogen fumarate is regarded as a classical antihistamine, whereas a possible effect on the superficial circulation of the skin is being discussed for isoprenaline.</p>","PeriodicalId":11073,"journal":{"name":"Dermatosen in Beruf und Umwelt.

Five concentrations of BA and MN in petrolatum were tested, on two subsequent days, without occlusion on the upper arm of 10 or 12 test subjects, with a dose of IRA irradiation that elevated surface temperature of the skin to 39.5 degrees C. In the first group exposed to IRA irradiation, the NIICR tests were performed immediately after the surface temperature of the skin had reached 39.5 degrees C; the skin was then allowed to cool down. In the second group exposed to IRA irradiation, the NIICRs were performed after a skin temperature of 39.5 degrees C was attained, and the skin temperature was kept unchanged for another 15 min. In the 1064 nm laser exposure group of 12 subjects, the tests were performed on the upper back immediately after irradiation of the skin with 100, 50, and 25 J/cm2 of neodymium yttrium aluminium garnet (Nd-YAG) laser (1064 nm). Reactions were monitored with laser-Doppler flowmetry 20 and 40 min after application, and erythema and edema reactions were graded visually. In the first group exposed to IRA, the warming had an enhancing effect on only one reaction induced by MN.
