Abstract
The chemicals were administered, subcutaneously, orally or topically. Generally, the depilation produced in the mice by mimosine or cyclophosphamide differed from that produced by the steroid analogues tested. In the first 2 cases almost completely naked mice were commonly seen, while in the steroid-treated groups the complete inhibition of all hair fibres was rare. This is discussed in relation to the effects of the same compounds on wool growth in sheep. When related to body weight, the doses of cyclophosphamide (62 mg/kg0.75) and dexamethasone (5-10 mg/kg0.75), that depilated mice in our experiments were in good agreement with those reported to inhibit the growth of wool fibres in some sheep.
An example of synergism in depilatory effect between dexamethasone and cyclophosphamide is also presented.
The time of onset and the initial spread over the body of the 2nd hair cycle in depilated mice was observed.
