Tetrahymena pyriformis, strains NT-1 and W, harvested in logarithmic (growing) and stationary (non-growing) phases, were found by high-performance liquid chromatography to contain considerable quantities of dopamine. In addition, small amounts of epinephrine and norepinephrine were detected. Logarithmic-phase strain NT-1 cells contained 249 +/- 44 pg dopamine/10(6) cells compared to 477 +/- 42 pg/10(6) cells for logarithmic-phase strain W cells for logarithmic-phase strain W cells. The dopamine content of stationary-phase cells was approximately half the value of the logarithmic-phase cells. There was a significant amount of dopamine in the growth medium from stationary-phase cultures and, to a lesser extent, logarithmic-phase cells.
梨形四膜虫NT-1株和W株,分别处于对数生长期(生长阶段)和稳定期(非生长阶段)收获,通过高效液相色谱法发现含有大量多巴胺。此外,还检测到少量肾上腺素和去甲肾上腺素。对数生长期的NT-1株细胞含有249±44 pg多巴胺/10⁶个细胞,而对数生长期的W株细胞为477±42 pg/10⁶个细胞。稳定期细胞的多巴胺含量约为对数生长期细胞的一半。在稳定期培养物的生长培养基中存在大量多巴胺,对数生长期细胞中含量较少。
