利用胃镜活检材料测定胃粘膜的LDH 同功酶国内曾有报告。黄光琦等对5例正常胃组织、9例胃癌组织进行了LDH 同功酶测定,发现前者酶谱分布以LDH_1、LDH_2、LDH_3为主峰,后者以LDH_3、LDH_4、LDH_5为主峰。但未指出正常胃组织和胃癌组织的确切部位(胃体或胃窦)。黄介飞等分别测定胃体和胃窦部粘膜LDH 同功酶谱,胃体部以LDH—H 型为主,胃窦部以LDH—M 型为主。我们对上消化道不同部位粘膜的LDH 同
The use of gastroscope biopsy material to determine the gastric mucosal LDH isozyme has been reported in China. Huang Guangqi et al. performed LDH isoenzyme assay on 5 normal gastric tissues and 9 gastric cancer tissues and found that the former had LDH_1, LDH_2, and LDH_3 as the main peaks, and the latter had LDH_3, LDH_4, and LDH_5 as the main peaks. However, the exact site (gastric or gastric antrum) of normal gastric tissue and gastric cancer tissue was not pointed out. Huang Jiefei et al. respectively determined the LDH isoenzyme spectrum of the corpus and gastric antrum, the LDH-H type in the gastric body, and the LDH-M type in the gastric antrum. We have the same LDH for different mucosa in the upper gastrointestinal tract
