¹H-NMRによるテトラヒメナ細胞中の水の状態に対するγ線照射の効果についての研究

抄録

The gamma irradiation effect on the state of water in Tetrahymena pyriformis was studied by¹H-NMR. The spin-lattice relaxation time (T₁) value was measured, in which the transient spectra after 180° pulse were observed varying pulse interval (PI) . This method revealed the appearance of another small peak of water together with the main peak of water in irradiated cells, whereas any small peak of water was not observed in unirradiated cells. The T₁value of the small peak was short compared with that of the main peak, suggesting that the water corresponding to the small peak is different from that corresponding to the main peak.
