We have studied the ultrastructure of the pinealocyte after 24 h of immobilization. Thirty male albino rats (230 +/- 10 g) were used; the animals were divided into two groups of 15 each. One group was immobilized for 24 h (10.00 h a.m. to 10.00 h a.m.), whereas the other group was used as control. All animals were sacrificed between 10.00 and 14.00 h of the following day. Ultrastructural observations showed an euchromatinic nucleus with numerous giant 'lipid droplets' as well as abundant long 'synaptic ribbons' that were significantly more abundant than in the controls (p < 0.0005). These findings all suggest an increase in pineal activity following 24-hour immobilization.
我们研究了固定24小时后松果体细胞的超微结构。使用了30只雄性白化大鼠（体重230±10克）；将动物分为两组，每组15只。一组固定24小时（上午10:00至次日上午10:00），而另一组用作对照。所有动物在次日10:00至14:00之间处死。超微结构观察显示，松果体细胞的细胞核呈常染色质状态，有大量巨大的“脂滴”以及丰富的长“突触带”，其数量明显多于对照组（p<0.0005）。这些发现均表明，固定24小时后松果体的活性增强。
