Effects of persistent overwork on the deep-sea fishermen: influence on serum cortisol and prolactin, and on urinary catecholamine levels. Variations in serum prolactin and cortisol levels and in urinary catecholamines levels were studied in fishermen exposed to a persistent overwork period of deep-sea fishing. Results indicate that prolactin was rapidly modified. In fact, the serum prolactin levels already increased on the first day and maximum levels were observed on the fifth day. On the contrary, the physiological rise and fall in the serum levels of cortisol were scarcely influenced on the first day while on the fifth day increased in the morning and fell in the evening in a very significant manner. No significant variation in urinary catecholamine levels was observed at the end of fifth day. These results suggest that, unlike for prolactin, the effects of stress on serum levels of cortisol are complex and, under our conditions, could be due, at least in part, to the duration of the stress and to the functional moment of pituitary-adrenal axis.
对血清皮质醇和催乳素以及尿儿茶酚胺水平的影响。对经历长期深海捕鱼过度劳累期的渔民的血清催乳素和皮质醇水平以及尿儿茶酚胺水平的变化进行了研究。结果表明，催乳素迅速发生改变。事实上，血清催乳素水平在第一天就已升高，并在第五天达到最高水平。相反，血清皮质醇水平的生理性升降在第一天几乎未受影响，而在第五天早晨显著升高，晚上则显著下降。在第五天结束时，尿儿茶酚胺水平未观察到显著变化。这些结果表明，与催乳素不同，压力对血清皮质醇水平的影响是复杂的，在我们的条件下，至少部分可能归因于压力的持续时间以及垂体 - 肾上腺轴的功能时刻。
