银狐、蓝狐及貉松果体的形态及组织结构初步研究

Primary Study on Structure of the Pineals of Silver Fox,Blue Fox and Racoon Dog

银狐、蓝狐及貉松果体的形态位置相近。３ 种动物松果体的不同之处是：蓝狐松果体体积最大，细胞密度最小，毛细血管最丰富，银狐松果体毛细血管比貉多一些，细胞密度稍小，银狐松果体细胞核直径平均为５－２ μｍ ，蓝狐平均为４－６ μｍ ，貉平均为４－３ μｍ 。

The pineal of silver fox,blue fox and racoon dog is similar in shape.The difference of pineals among these three kinds of animals is that pineal volume is the biggest and pinealocyte density is the least and the capillary vessel is the most abundant in blue fox.There more capillary vessels and less pinealocyte density in silver fox than in racoon dog.Average diameter of the pinealocyte nuclear is 5.2 μm in silver fox and 4.6 μmin blue fox and 4.3 μm in racoon dog.
