title: [Release of chromium 51 by coxsackievirus-infected FL cells].
abstract: The time course of chromium-51 (51Cr) release was investigated on FL monolayer cells infected with different serotypes of coxsackievirus. 51Cr release was determined by means of the increase in 51Cr radioactivity in supernatants of cells saturated with 51Cr. Ten hours p.i. the 51Cr release of virus-infected cells was largely increased compared with the control cells. The greatest differences in 51Cr release between normal and virus-infected cells were observed from 10 to 30 hours p.i. The quantitative correlation between virus concentration and 51Cr release as well as the type-specific inhibition of virus-accelerated 51Cr release by virus-neutralizing antisera demonstrate the relationship between 51Cr release and coxsackievirus infection of FL cells. By the use of 51Cr labeled FL cells as an indicator system, the 51Cr release proved to be well suited for objective and quantitative evaluation of coxsackievirus-cell-interactions connected with the cytopathogenic effect (CPE).
