C-8 STUDY
Please find attached charts of data developed from reviewing medical records on 51 employees with the highest measured levels of C-8 1n their blood. It would be logical to expect that any disease attributable to C-8
should be found 1n employees with the highest levels of C-8.
In my opinion, very little evidence of disease due to C-8 was found. We did find several employees with frequent elevations of blood tests (SGOT - 7, Alkaline Phosphatase - 10, LDH - 7) but no evidence of liver disease. Perhaps C-8 was the cause of these elevations, but no controlled studies were done. We also found 2 cases of kidney disease and one case of thrombocytopenla/leukopenla that could not be attributable to some other
cause. The significance of these 1s unclear to me.

Please let me know how we should proceed with this study.
