ACKNOWLEDGMENT 
We would like to acknowledge Drs. Frank 
Heck, LaVal Cothran and Mr. John Fuqua for 
their spirited and creative support during these 
studies. We also acknowledge the technical as- 
sistance of H. Gilmer, C. Poe and J. Wells. We 
are indebted to Miss Susan Green for her dedi- 
cated secretarial assistance. Finally, special 
commendation is given to the late Dr. Frank W. 
Hastings, who envisioned and supported the de- 
velopment of the conscious preparation for 
medical research.
