title: Investigation on the reaction of molybdenum with collagen in vivo.
abstract: Male Wistar rats were treated with Mo in a single dose or over a period of 84 days. The course of molybdenum excretion after a single dose was expressed mathematically. It was shown that various tissues produced different excretion curves and a high retention was observed only in skin. In long-term treatment it was possible to ascribe this retention to direct binding of molybdenum to collagen. In contrast to some other heavy metals molybdenum causes a decrease of collagen stability. The mechanism of this effect is discussed.
