title: [Influence of x-rays on depolymerization of lathyric collagen fibers reconstituted in vitro].
abstract: Irradiation of native collagen from lathyric rats in solution reduces the depolymerisation speed in the cold of fibres formed by gelification at 37 degrees C, rendering it thus comparable to the speed observed with normal collagen. In our test this normalisation does not appear if the collagen is irradiated in the state of gel. These observations and the absence of specific modifications induced by irradiation in the presence of reagents of the aldehydes speak in favour of the interference, on irradiation, of chemical groups different from the physiological aldehyde groups.
