The present investigation tries to reflect histochemical and stereological properties of the parotid gland (PG) and sublingual gland (SLG) in the Caucasian squirrel. Totally, five male Caucasian squirrels were used. The glands were examind histochemical using PAS, Alcian blue (AB, pH = 2.5) and Aldehyde fucshin (AF) stainings. Total volume of the glands, acini, ducts as well as total length of ducts were estimated using streological procedures. The PG had a unique morphology and were connected to each other with an intermediated isthmus. The SLG was oval-shaped. Serous acini of PG exhibited strong, negative and weak reaction with AF, AB and PAS, respectively. While, mucous acini of SLG showed positive staining for AB and PAS, and negative staining for AF. The ductal system was consisted of intercalated (Id), striated (SD) and excretory ducts (Ed). The Sd in PG was lined with simple cuboidal to the columnar epithelium, while it was lined with simple cuboidal epithelium in SLG. The Ed was lined with stratified cuboidal epithelium in both glands. The striated duct was longest duct in both glands, the excretory and intercalated ducts were the shortest ones in PG and SLG, respectively. The maximum total volume in both gland were blonged to the acini and straited ducts. It concluded that PG and SLG in the Caucasian squirrel have some distinct structural properties in comparison to other rodents and mammalis species.

本研究试图反映高加索松鼠腮腺 (PG) 和舌下腺 (SLG) 的组织化学和体视学特性。总共使用了五只雄性高加索松鼠。使用 PAS、阿尔新蓝 (AB, pH = 2.5) 和醛品红 (AF) 染色检查腺体的组织化学。腺体、腺泡、导管的总体积以及导管的总长度是使用流学程序估计的。PG具有独特的形态，并通过中间峡部相互连接。SLG 是椭圆形的。PG浆液腺泡对AF、AB和PAS分别表现出强、阴性和弱反应。而SLG的粘液腺泡AB和PAS呈阳性染色，AF呈阴性染色。导管系统由闰（Id）、横纹（SD）和排泄管（Ed）组成。PG中的Sd为柱状上皮内衬简单立方上皮，而SLG中为简单立方上皮。Ed 在两个腺体中都衬有复层立方上皮。横纹管是两个腺体中最长的管，排泄管和闰管分别是PG和SLG中最短的。两个腺体中的最大总体积被扩大到腺泡和狭窄的导管。得出的结论是，与其他啮齿动物和哺乳动物相比，高加索松鼠中的 PG 和 SLG 具有一些不同的结构特性。排泄管和闰管分别是 PG 和 SLG 中最短的。两个腺体中的最大总体积被扩大到腺泡和狭窄的导管。得出的结论是，与其他啮齿动物和哺乳动物相比，高加索松鼠中的 PG 和 SLG 具有一些不同的结构特性。排泄管和闰管分别是 PG 和 SLG 中最短的。两个腺体中的最大总体积被扩大到腺泡和狭窄的导管。得出的结论是，与其他啮齿动物和哺乳动物相比，高加索松鼠中的 PG 和 SLG 具有一些不同的结构特性。
