Microvascular cast specimen formation of lingual papillae in zinc-deficient rat tongue.
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.
