SOME PROTECTION METHODS FOR CUTANEOUS IRRADIATION WITH FAST ELECTRONS (in Italian)
The influence exerted by some substances, particularly by fatty substances and cortisone derivatives, on the skin reaction to fast electrons is examined. The means employed were applied on the skin immediately before the irradiation; their effectiveness varies in relation with the dose fractionation; this decreases in general the capacity of the various substances tested of modifying the skin reaction. The changes induced by these means are both quantitative and relative to the course (anticipation of the appearance of the erythema); they may occur uniformly in all phases of the reaction or only in one (a change of the first phase of the erythema is usually observed). The quality of the excipient, the action of which is often responsible for the aggravation of the skin reaction, is to be taken into account in the evaluation of the typical effect of the medications. Within the limits of the doses employed (1000 rad in only a sitting, 5000 rad in case of fractionation) the influence of fatty substances on the skin reactions due to irradiation with quick electrons proved not to be marked but only scarcely appreciable. The mineral fats may increase the reaction due to quick electrons in some cases: they do not have, however, either a protective or therapeutic effect during the acute phase of the reaction. The cortisone derivatives are uneffective when they are directly and exclusively applied on the irradiated skin, while they are successfully used by general route, especially in the reactions of the mucous membranes produced by quick electrons; in any way, the topical use of cortisone derivatives with excipients deprived from mineral fats proved to be preferable. Among the physical means employed, the compression gave the best results, in the cases where it could be applied. (auth)
