病理的内源性沉着物是色素沉着物的一部分,组织细胞经过一定的病理变化,形成不同形状特点的沉着物质,这种聚合形成的特殊蛋白,经染色后能够显示纤维素蛋白。纤维素是存在于血液内的纤维蛋白分子聚合形成的特殊蛋白质,又称为纤维蛋白,在正常的情况下它是血液内的纤维蛋白原分子聚合而形成的一种特殊蛋白质,这种蛋白以弯曲细丝纤维素的形式存在于组织内,大多数呈网状结构,有时会呈粗大的纤维素网,陈旧的可凝集呈无定型的块状。当组织受损时,血管内皮受到了较为严重的损害,血管通透性随之升高,则可导致大量纤维蛋白的漏出。
纤维素染色液 (改良MSB法)是一种简便、廉价的纤维素染色液,染色后纤维素呈红色或蓝色。
使用方法
1、组织经固定,常规脱水包埋,常规脱蜡至水。
2、入硫代硫酸钠溶液,处理3-5min,稍水洗。
3、入天青石蓝染色液,染色3-5min。
4、入Mayer苏木素染色液,染色3-5min。
5、酸性乙醇分化液分化数秒,流水冲洗10min。
6、95%的乙醇稍洗。
7、入马休黄染色液,染色2-3min,蒸馏水稍洗。
8、入酸性品红染色液,染色10min,蒸馏水稍洗。
9、磷钨酸溶液处理切片,直至胶原蛋白红色接近无色,蒸馏水稍洗。(镜下观察,一般处理5-10min)
10、入苯胺蓝染色液,染色5-10min。
11、弱酸溶液稍洗,吸纸吸干。
12、95%的乙醇急速洗2次。
13、无水乙醇脱水,二甲苯透明,中性树胶封固。
染色结果
纤维素: 红色 (陈旧性纤维素呈蓝色至紫黑色)
肌纤维: 红色
细胞核: 蓝灰褐色
胶原纤维: 蓝色
红细胞: 黄色
注意事项
1、磷钨酸溶液处理切片,一方面是把染上红色的胶原纤维分化至接近无色,另一方面是对胶原纤维起媒染作用,使得胶原纤维与苯胺蓝较牢固结合。
2、切片如用Bouin液媒染后再按上法染上则效果更好。
3、苯胺蓝染色一般5min即可,但应每隔2min观察一次,防止过染,否则蓝色过深。
4、为了您的安全和健康,请穿实验服并戴一次性手套操作。
Endogenous pathological deposits are a subset of pigment deposits. After undergoing certain pathological changes, histiocytes form deposits with different morphological characteristics. These polymerized special proteins can be stained to reveal fibrin proteins.Fibrin is a special protein formed by the polymerization of fibrinogen molecules in the blood, also known as fibrin. Under normal physiological conditions, it is produced by the polymerization of fibrinogen molecules in the blood. This protein exists in tissues in the form of curved fibrin filaments, mostly presenting a reticular structure, and sometimes forming coarse fibrin networks. Old fibrin can aggregate into amorphous masses. When tissues are damaged, vascular endothelial cells suffer severe injury, leading to increased vascular permeability, which in turn causes massive leakage of fibrin.
Fibrin Staining Solution (Modified MSB Method) is a simple and cost-effective fibrin staining solution. After staining, fibrin appears red or blue.
Operating Procedure
1. Fix the tissue, perform routine dehydration and embedding, then conduct routine dewaxing to water.
2. Immerse the tissue in Sodium Thiosulfate Solution for 3–5 minutes, followed by a brief rinse with water.
3. Transfer to Celestine Blue Staining Solution and stain for 3–5 minutes.
4. Move to Mayer's Hematoxylin Staining Solution and stain for 3–5 minutes.
5. Differentiate with Acid Alcohol Differentiating Solution for several seconds, then rinse thoroughly under running water for 10 minutes.
6. Rinse briefly with 95% ethanol.
7. Immerse in Martius Yellow Staining Solution for 2–3 minutes, then rinse briefly with distilled water.
8. Transfer to Acid Fuchsin Staining Solution and stain for 10 minutes, followed by a brief rinse with distilled water.
9. Treat the sections with Phosphotungstic Acid Solution until the red color of collagen fibers fades to nearly colorless, then rinse briefly with distilled water. (Observe under a microscope; the treatment usually takes 5–10 minutes.)
10. Immerse in Aniline Blue Staining Solution and stain for 5–10 minutes.
11. Rinse briefly with Weak Acid Solution and blot dry with absorbent paper.
12. Rinse rapidly twice with 95% ethanol.
13. Dehydrate with anhydrous ethanol, clear with xylene, and mount with neutral balsam.
Staining Results
Fibrin: Red (old fibrin appears blue to purple-black)
Muscle fibers: Red
Cell nuclei: Blue-grayish brown
Collagen fibers: Blue
Red blood cells: Yellow
Precautions
1. The treatment with Phosphotungstic Acid Solution serves two purposes: first, it differentiates the red-stained collagen fibers to nearly colorless; second, it acts as a mordant for collagen fibers, enabling them to bind more firmly to aniline blue.
2. Better staining results can be achieved if the sections are mordanted with Bouin's solution before proceeding with the above staining procedure.
3. Aniline blue staining generally takes 5 minutes. However, observe the sections every 2 minutes to avoid over-staining, which would result in excessively deep blue coloration.
4. For your safety and health, wear a lab coat and disposable gloves during operation.
