Carman and Levy (1944) and Vislocki et al. (1945) found that nitrogen mustards in small concentrations produced a delay in the rate of cleavage of sea urchin eggs. In their experiments M MBA was added to a suspension of eggs, and 20 minutes later the eggs were washed and fertilized with non-treated sperm. Under those conditions, while first cleavage (50 per cent) took place in 56 minutes in the control eggs, it required 78 minutes in the MBA treated eggs. Treatment just before fertilization started retarded first division but not the second division. The inhibition of cell division was found more effective when the sperm was treated with nitrogen mustard, as can be seen in the two series of Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Marine Biological Laboratory (Woods Hole, Mass. ); Marine Biological Laboratory (Woods Hole, Mass. ).
