In Heteropneustes fossilis, the adrenocortical cells were highly active, hypertrophied, and degranulated after 15 and 30 days of pinealectomy in spawning/postspawning phase. Besides, several cells had undergone pycnotic changes in the 30-day group. The plasma cortisol level increased significantly (P less than 0.05) in the pinealectomized fish in comparison to those of the sham pinealectomized and unoperated control fish. The increase was higher in the 15-day group than in the 30-day-pinealectomized group. The results suggest that the pineal organ exerts an inhibitory influence on the activity of the adrenal in the catfish.
在印度胡鲶中，处于产卵期/产卵后期的鱼在松果体切除术后15天和30天，肾上腺皮质细胞高度活跃、肥大且脱颗粒。此外，在30天组中，几个细胞发生了核固缩变化。与假松果体切除组和未手术的对照鱼相比，松果体切除的鱼血浆皮质醇水平显著升高（P小于0.05）。15天组的升高幅度高于30天松果体切除组。结果表明，松果体器官对鲶鱼肾上腺的活动有抑制作用。
