Abstract

The aim of this study was to investigate postnatal changes that might occur on vallate papilla of laboratory mice by using light and scanning electron microscopy (SEM). Eight groups were formed for 1, 15, 30, 60, 90, 120, 150 and 180 days old mice and 8 mice were used in each group. Micrometric measurements of vallate papilla which was located median line on dorsal surface of radix area of tongue showed that development of this papilla was very fast for first 15 days period. After then, increases in length and width of papilla and depth and width of trench were slowed down but development continued to 120th day. First mature taste buds which had taste pores were seen on 4th the day of the age. Increase of length and width of taste buds continued by 90th day, increase of number of taste buds continued by 30th days. Trench wall surface area increased 136% in first 15 days period, after this period by 90th day it develop in parallel to the age. In the structure of scanning electron microscopy of vallate papilla, epithelial cell-margin thickness was evident and had micropits and microridges on the surface cells. As a result, it is detected that vallate papillae developed by 120th day and taste buds developed and became functional in the first 4 days.

Özet

Çalışmada; laboratuar farelerinde papilla vallata'da meydana gelen ışık ve taramalı elektron mikroskopik postnatal değişimlerin ortaya konulması amaçlanmıştır. Bu amaç için 1, 15, 30, 60, 90, 120, 150 ve 180 günlük 8 grup oluşturuldu ve her grupta 8'er fare kullanıldı. Ayrıca ilk olgun tat tomurcuğunun oluşum zamanının tespiti için de 0-10. günler arasında her gün iki fare kullanılmak üzere, toplam 84 fare kullanıldı. Dilin kök bölgesi dorsal yüzünde median hat üzerinde yerleşmiş tek olarak bulunan papilla vallata'da yapılan mikrometrik ölçümlerde ilk 15 günlük periyotta çok hızlı bir gelişimin olduğu dikkat çekicidir. Papilla genişliği ve uzunluğu ile hendek derinliği ve genişliğindeki artış bu periyottan sonra yavaş bir artış göstererek 120. güne kadar devam etmektedir. Tat porusu şekillenmiş ilk olgun tat tomurcuğu 4. günde görülmüştür. Tat tomurcuğu uzunluk ve genişliğindeki artış 90. güne, tat tomurcuğu sayısındaki artış ise 30. güne kadar devam etmektedir. Hendek duvar yüzey alanı da yine ilk 15 günlük periyotta % 136'lık bir artış göstermekte, bu periyottan sonra ise 90. güne kadar yaşın ilerlemesine paralel bir artış göstermektedir. Papilla vallatanın taramalı elektron mikroskobik yapısında yüzey epitel hücrelerinin sınırları belirgin ve hücre yüzeylerinde micropit ve microridge mevcuttu.
