死産植物の舌の発達は、さまざまな妊娠年齢で剖検されました

目的：この研究は、形態計測法、舌の周囲と長さ、コラーゲン繊維、およびさまざまな妊娠年齢と胎児の重量での血管の境界を分析することを目的としています。 材料と方法：妊娠23〜40週間で老化した死bornsの舌（n = 55）をqu鏡的に分析し、それらの長さと周囲を測定しました。55の舌の断片は、舌の中央溝に伴う領域の縦方向の部分を介して収集され、組織学的に処理されました。スライドをピクロシリウスで染色し、CD31抗体で免疫標識しました。偏光下のコラーゲン繊維、およびCD31の血管周囲で定量化を行いました。 結果：妊娠年齢と舌周囲と長さの正で有意な相関が見つかりました。コラーゲン繊維と妊娠年齢との間に、ならびに妊娠年齢と血管の周囲の間には正の有意な相関がありました。コラーゲン繊維と胎児の体重の間で、正で有意な増加が観察されました。血管の周囲と胎児の体重との相関については、増加が観察されました。 結論：妊娠年齢が進むにつれて、コラーゲン繊維の割合、および血管周囲の舌周囲と長さが増加し、舌の形成が舌の成長と発達に直接関連していることを示しています。

OBJECTIVES: This study aimed to analyze, through the morphometric method, the perimeter and length of the tongue, the collagen fibers, and the perimeter of blood vessels at different gestational ages and fetal weights. MATERIAL AND METHODS: Tongues (n=55) of stillborns autopsied at 23-40 weeks of gestational age were macroscopically analyzed, and their length and perimeter were measured. Fifty-five tongue fragments were collected through a longitudinal section in the region that accompanies the median lingual sulcus and histologically processed. Slides were stained with picrosirius and immunolabeled with CD31 antibody. Quantification was performed on collagen fibers under polarized light, and on the perimeter of vessels with the CD31. RESULTS: A positive and significant correlation of gestational age with tongue perimeter and length was found. There was a positive and significant correlation between collagen fibers and gestational age, as well as between gestational age and the perimeter of blood vessels. Between collagen fibers and fetal weight, a positive and significant increase was observed. Regarding the correlation between the perimeter of blood vessels and the fetal weight, an increase was observed. CONCLUSION: As gestational age advances, there is an increase in tongue perimeter and length, in the percentage of collagen fibers, and in vascular perimeter, demonstrating that tongue formation is directly related to tongue growth and development.
