松果腺(pineal gland)位于中脑四叠体的上丘之前,是一个园锥形小腺体。曾被认为是一个退化器官,但近来越来越多的学者认为它是具有多方面生理功能的器官,我们以猪松果体为材料进行研究。由北京食品公司车间直接从猪头部取下新鲜松果体,冷却下保存,以生理盐水洗去血液,弃去其它组织,吸干称重。每批取20或10个松果体试验。称重后在冷却下剪碎,以生理盐水在 Pineal gland (pineal gland) is located in the upper quadrant of the midbrain in front of the hill, is a small conical garden gland. Once thought to be a degenerative organ, but more and more scholars recently think it is a multi-functional organ, we study the material of pineal gland. Take the fresh pineal gland directly from the head of the pig by Beijing Foodstuff Workshop and save it under cooling, wash away the blood with saline, discard other tissues, and dry it and weigh it. Take 20 or 10 pineal body tests per batch. After weighing under cooling cut, with saline in the
