Nuclear magnetic resonance (NMR) pulse techniques were used to obtain values for the spin-lattice relaxation time (T1) of whole blood, plasma, blood cells, in vitro liver samples, and live and necrotic tail samples for adult Taricha granulosa. The T1 for whole blood is (0.80 +/- 0.01) s, for plasma (0.76 +/- 0.02) s and for blood cells (0.83 +/- 0.01) s, and did not change over several hours of measurement. The necrotic liver gave a single T1 of (0.28 +/- 0.02) s within the first 20 min of excision with a gradual increase over the next 3.5 h. Live and dead tail samples gave two T1 values: a short T1 of about 0.15 s remaining essentially constant and a long T1 starting at 0.68 s and increasing to 0.9 s during the 5 h of the experiment.
采用核磁共振（NMR）脉冲技术来获取成年粗皮蝾螈全血、血浆、血细胞、体外肝脏样本以及活体和坏死尾部样本的自旋晶格弛豫时间（T1）值。全血的T1为（0.80±0.01）秒，血浆为（0.76±0.02）秒，血细胞为（0.83±0.01）秒，并且在数小时的测量过程中没有变化。坏死肝脏在切除后的最初20分钟内给出单一的T1值为（0.28±0.02）秒，在接下来的3.5小时内逐渐增加。活体和死亡尾部样本给出两个T1值：一个约0.15秒的短T1基本保持恒定，一个长T1从0.68秒开始，在实验的5小时内增加到0.9秒。
