The ultrastructure of the turkey Harderian gland is described and the findings support previous histological descriptions of the gland. The gland is a compound tubulo-acinar structure composed of characteristic bipolar epithelial cells providing a predominantly merocrine secretion to the lumina. In the basal aspect of the cell, aggregations of non-secretory lipid-like droplets were evident and apically, the secretion was mucoid. The cells had abundant mitochondria, granular endoplasmic reticulum, ribosomes and a complex network of Golgi elements. In the subepithelial regions, myoepithelial cells and large numbers of plasma cells were seen. Within the granular endoplasmic reticulum cisternae of the epithelial cells, fibrillary or crystalline rods in some instances measuring up to 10 micron in length, with a 7.0 nm repeat pattern, were frequently seen.

本文描述了火鸡哈德氏腺的超微结构，研究结果支持了此前对该腺体的组织学描述。该腺体呈复管泡状结构，由特征性的双极上皮细胞组成，主要向管腔进行局浆分泌。在细胞基部，可见非分泌性脂样小滴聚集，而在细胞顶部，分泌物为黏液样。细胞具有丰富的线粒体、粗面内质网、核糖体以及复杂的高尔基体网络。在皮下区域，可见肌上皮细胞和大量浆细胞。上皮细胞的粗面内质网池内，常可见到一些长度可达10微米、重复模式为7.0纳米的纤维状或结晶状杆状物。
