ABSTRACTWe compared growth enhancement of radish induced by O2, air, and Ar plasma irradiation. The average length of radish sprouts cultivated for 4 days after O2plasma irradiation is 70% longer than that of sprouts without irradiation. The O2plasma irradiation is more effective in enhancing growth than air and Ar radio frequency plasma irradiation. Cell morphology and cell size of sprouts with O2plasma irradiation is nearly the same as those without irradiation. These results suggest that plasma induced acceleration of cell proliferation brings about the rapid growth.

Pertinent Data

Recent trends in the field of in vitro toxicology have centred around the validation of in vitro methods. The ultimate goal is to obtain pertinent data with the minimum of effort. In our laboratory, we have used toxicological methods based on the evaluation of cell morphology and cell proliferation. A method suitable for this purpose is time-lapse microcinematographic (or video) recording of cellular changes, which we used for many years. For practical in vitro toxicity testing, however, this method is far too complicated. Therefore, we have tried to develop a simple modification for the evaluation of cell morphology and cell proliferation, which would still allow for a basic time-dependent analysis. Comparison of detailed microcinematographic analysis with analysis according to our new proliferation assay is demonstrated with cisplatin as the toxicant. We believe that a time-dependent approach could improve the in vitro assessment of toxicity.

Differential Development

Our study of the effect of the lead ion on the development of the chick embryo has brought out the following facts: 1. Gross growth is retarded. 2. Somite growth is retarded to a degree greater than that exhibited by body length and width. 3. The head and optic anlagen are regions of particular sensitivity. Their differential development is markedly inhibited. From the purely biological point of view these results are in line with the findings of Child (10) and his school as to the sensitivity of the head end of rapidly growing organisms to harmful influences, and with those of Stockard (11) as to the peculiar sensitivity of the optic anlagen. It is almost too well known to need repetition that the head region and the somites of embryos are specific areas of intense growth by increase in cell number. Therefore, turning from the general to the particular, the differential retardation of these regions which is caused by lead, is evidence justifying the conclusion that it is areas of rapid growth by cell proliferation which are selectively inhibited by this metallic ion.
