Re: Hormetic Effects of Radiation should not be limited to cancer

[Bernard Cohen <blc+@PITT.EDU>]

My apologies for the fact that the Table was garbled..  I give an 

ungarbled version here. As shown, the exposures are 2.5, 5.0, and 7.5 

cGy. All numberes are relative to 100 for unexposed mice.



Effects of radiation on immune response.  Different columns are percent 

of response to various tests in unexposed mice to response in mice 

exposed as indicated [15]. PFC = plaque forming cell; MLC = mixed 

lymphocyte culture, used as  test of T-cell function; Con A = 

concanavalin-A,  lectin that stimulates T-lymphocytes; NK = natural 

killer cells which recognize and kill tumor cells; ADCC = anti-body 

dependent cell mediated cytotoxicity, which assists NK activity.
