Abstract

Experimatal maxillary sinusitis was induced in New Zealand white rabbits by blocking the maxillary sinus ostium. The distribution of lectin receptors was explored in the mucosa with induced maxillary sinusitis using colloidal gold label complex with lectin WGA purified from wheat germ (Triticum vulgaris). The lectin WGA gold complex, shown to recognize GlcNac (N-acetylglucosamine) and NeuNAc (N-acetylneuraminic acid) regions, was applied to detect binding sites in Lowicryl HM 20 sections and viewed under the electron microscope. An increased height of the cylindric cells, ciliary loss and hyperplasia of the secretory cells were observed. Examination of normal sinus mucosa labeled with gold-labeled lectins showed the distribution of sialoglycoconjugates to be mainly in the ciliary layer and the granules in the secretory cells. Inflamed mucosa had increased labeling intensity of gold-labeled WGA in the cilia and the secretory granules. These results indicate that lectin WGA receptors are located in the cilia and secretory granules. Specific changes in the lectin binding pattern were apparent in the inflamed mucosa in the experimentally induced acute sinusitis, in comparison with normal mucosa, conceivably as a part of host defense reactions.

분비세포와 점막고유층 점액분비세포로부터 분비된 점액으로 덮여있으며, 비점막 및 하기도를 보호하는 생체방어기능을 갖고 있는 실험토끼의 비점막에 상악동염이 유발되었을 때 점막 분비세포 수적 증가와 분비물질의 변화를 규명하기 위하여 전자현미경으로 미세구조적 특성을 관찰하였다. 또한 점막 당단백질 말단기인 sialic acid의 염증시 분포양상을 알아보고자 sialic acid에 특이적으로 반응하는 lectin인 WGA를 황금입자가 표지된 lectin WGA 복합체를 반응시키고 투과전자현미경으로 관찰하였다. 그 결과 염증이 없는 실험 토끼들의 정상 상악동 점막상피세포는 균일한 높이의 섬모를 갖는 상피 세포층에 부분적으로 분비세포가 관찰되었다. 분비세포는 전자밀도가 높은 과립과 전자밀도가 낮은 과립을 포함하고 있는 것이 관찰되었다. 상악동염을 유발시킨 실험 토끼들의 점막상피세포는 상피 세포층이 비후되었으며 분비세포 수가 증가하였고 부분적으로 섬모가 소실되었다. 이러한 변화는 상피세포 표면에 세균의 부착을 막는 일차적인 방어체제인 점액의 증가로 화농성의 분비물이 생성되어 섬모의 기능을 손상시키는 것으로 확인되었다. Lectin WGA 반응에서 정상 섬모세포의 섬모와 분비세포의 전자밀도가 낮은 과립에 sialic acid를 포함하고 있는 것으로 확인되었다. 상악동염이 유발된 실험토끼의 점액에 lectin WGA 반응 결과 섬모세포의 섬모와 분비세포의 전자밀도가 낮은 과립에서 sialic acid의 분포가 급격히 증가하는 것으로 관찰되었다. 따라서 점막에 염증이 유발되면 분비세포와 점막의 분비세포의 증식으로 sialic acid를 포함한 sialogylcoconjugate의 과다분비가 유발되며 이는 분비세포가 염증으로 인해 생체가 외부자극에 나타내는 급격한 방어기전으로 생각되었다.
