At 2 hours, there was an increase in concentration at or near to the y globulin fraction, 2) Although Sr appears to be bound to protein during electro- phoresis it was found to move during thestaining and washing ng é rationstak Classification changed to Bal) 6c it imperative to do radioautograbh s#uer b.

Z Claef OP De ZLLee 66) ox (Signafute of person making ths chang3, and date) Two experiments have been carried out to confirm, the previously reported effect of dietary DHC on liver cholesterol concentration. In the first, plasma cholesterol levels were lower in the DHC fed animals (46.8%) than in the controls (71.4 mg %). Liver analyses were uncertain because of technical diffi- culties and the results are inconclusive. In the second experiment, a 2% DHC diet was fed for 10 days and the liver levels were found to be lower (2.17 mg/em, range of 1.99-2.35) than in the control group (2.55 mg/gm, range of 2.16-3.25). The serum values were also slightly lower, 54.3% for the DHC group, 64.2 for the controls. Although this difference was not as marked as in the original experi- ment, the decrease in level does seem to be a definite and consistent effect and one not observed with sitosterol. c, ‘, hn Tests of New Chelatine Arents.
