Results of lymphoproliferation assays using stimulation with PHA, HSV, and VZV.

The symbols are the same as in Figure 1. Only HSV (VZV)–infected patients with HSV (VZV)–infected donors were included in the analysis of HSV (VZV)–induced proliferation. The numbers of marrow recipients and blood stem cell recipients studied with PHA were 41 and 41, respectively, on day 30; 38 and 42 on day 80; 31 and 33 on day 180; and 27 and 30 on day 365. For HSV, the numbers of marrow recipients and blood stem cell recipients studied were 13 and 22, respectively, on day 30; 13 and 20 on day 80; 8 and 16 on day 180; and 6 and 14 on day 365. For VZV, the numbers of marrow recipients and blood stem cell recipients studied were 16 and 19, respectively, on day 30; 15 and 17 on day 80; 11 and 14 on day 180; and 10 and 12 on day 365.
