在最近的一篇综述中，Vallee和Altschule1指出，尽管许多工作者已经估算了活组织中的锌含量，但所用的方法往往是不准确的。我们用Vallee和Gibson2的双硫腙法估计了Collip帽鼠某些组织的锌含量。成年动物被喂食含有约75µgm的狐粮。每克锌，补充胡萝卜和卷心菜。大多数组织含有约15-30µgm。每克锌；但某些男性生殖器官显示出与这一范围有很大差异。尽管Bertrand和Vladesco3报道鲱鱼和马的睾丸、猪的精囊、大鼠的附睾以及公牛和人类的前列腺中锌含量很高，但文献中很少提及生殖系统中的锌含量。Kadota4简要地提到，锌可以用相对不敏感的组织化学方法在兔前列腺中检测到。莱纳和莱纳给出的大鼠睾丸和埃格尔顿给出的人类睾丸的数据都在哺乳动物软组织的通常范围内。
IN a recent review, Vallee and Altschule1 have suggested that though many workers have estimated zinc in living tissues, the methods used have often been inaccurate. We have estimated the zinc content of certain tissues of the Collip hooded rat by the dithizone method of Vallee and Gibson2. Mature animals were used which were fed on a diet of fox chow containing about 75 µgm. zinc per gm., supplemented with carrot and cabbage. Most tissues contained about 15–30 µgm. zinc per gm.; but certain male genital organs showed wide deviations from this range. The literature contains few references to the zinc content of the genital system, though Bertrand and Vladesco3 reported high results in herring's and horse's testis, pig's seminal vesicle, rat's epididymis and in the prostate of the bull and of man. Kadota4 mentioned briefly that zinc could be detected by a relatively insensitive histochemical method in the rabbit prostate. The figures given by Leiner and Leiner5 for rat's testis and by Eggleton6 for human testis were within the usual range for soft mammalian tissues.
