Model		2.8 GHz (PW) and other frequency RF exposures to cell cultures and bacteria and analysis of growth parameters
Details		Various studies looking at cell cultures exposed to RF. In the 1989 study, rat brain synaptosomes were exposed to 2.8 GHz (PW - 1 usec pulse width, 350 pulses/sec) microwaves at 1, 10, and 30 W/kg using a horn antenna. Exposure at 10 and 30 W/kg resulted in increased uptake of 32P into PIP, PIP2, PI, and PA, but did not change total concentrations of these metabolites suggesting that phosphoinositide turnover was stimulated. Competition studies with lithium, A23187 (Ca++ ionophor), and EGTA indicated a specific pool of inositol phospholipids in the synaptosomal membranes being acted upon by microwaves. The authors suggest these data indicate microwave exposure may affect transmembrane signalling in nerve endings.
