Pt, patient. 

*

Number of days before or after gene therapy. 

Vector p47phox cDNA sequence detected (+) or not detected (−) in blood leukocytes. All + were <0.1% of cells marked. 

The +/− indicates positive signal detected by Southern blotting of the PCR product but not by nested primer detection.
