P. 009 Protection is In prineipal the trandplantation of bone marrow vould significantly increase the survival rate of expos human beings in the group 2 (Survival possible) and possibly to a lesser extent ig the group 1 (Survival improbable) casualties. The amounts cf bone marrow neededlare large and the mongrel nature of man takes it unlikely that very much could be the way of long term rrotective effect. dxpected in In ny opinion it would be tile vorst type of wishful thinking to expect that one could iave an effective bone 1 arrow bank in the case of an atomic catastrophe. Mucdiwork is yet to be done um er carefully ccntrolled clinical conditions before ons could be optimistic about 1 lie use of this procedure in man under highly controlled conditions, for an im: vidual patient let alone under conditions of a nuclear catastrophe. Fovwever, the treatment of group 2 easuelties is not at all hope] ass There is ample clinical experience in conditions where the bone marrow is ; everely de~ pressed and in which there are inadequate numbers of circulating cel] gs. relatively common clinical conditions produced by sensitivity to dr in these gs, or cecurring naturally as disease processes, the combined use of the wide spectr antibiotica that are now available, and the judicious use of blood transfusions jgnificantly increases the survival time of the individuals, thus giving nature a longer period of time to repair spontaneously the damages that has been suffered. Accordingly one could feel optimistic in respect to increasing significantly the sur rival rate of the group 2 (Survival possible) casualties ty wide spread controlled use of anti= biotics.* Preparation and stockpiling for such an emergency is obvic usly required.
