Abstract

In the present study the microvascular cast specimens (MVCS) of lingual papillae (LP) in a zinc-deficient (Zn-deficient) rat group were compared with those of a control rat group, so as to observe and assess the effects on tongue changes in the Zn-deficient rat group by scanning electron microscopy (SEM). The main clear changes in LP in the Zn-deficient rat group were deformity, reduction in size and disturbed distribution of the filiform (FiP) and fungiform papillae (FuP) relating to taste sense. The results suggested that the Zn-deficient condition interfered with the microvascular circulation supplying nutrients to the LP.

摘要

在本研究中，将缺锌大鼠组舌乳头（LP）的微血管铸型标本（MVCS）与对照大鼠组的进行比较，以便通过扫描电子显微镜（SEM）观察和评估缺锌大鼠组中对舌变化的影响。缺锌大鼠组中LP的主要明显变化是畸形、尺寸减小以及与味觉相关的丝状乳头（FiP）和菌状乳头（FuP）分布紊乱。结果表明，缺锌状态干扰了向LP供应营养的微血管循环。
