SYNOPSIS. Excystment of Schizopyrenus russelli was associated with increase in DNA, RNA, and protein. Both excystment and these macromolecular increases were sensitive to ultraviolet radiation. The effect of UV was partly reversed by incubation in the dark at 28 C, but not at 4 C. Excystment from cysts preincubated in the excystment medium (before UV treatment) was relatively resistant to radiation.
