用5株溶组织内阿米巴(简称:Eh)分别作仓鼠肝内接种,观察肝阿米巴病的病理学特征。仓鼠产生的肝脏病变与人的相似。脓肿内壁表面不规则,中央呈不同程度液化性坏死。在脓肿内壁变性的肝细胞和坏死组织之间可见大量阿米巴滋养体,其体积大小不一,有些滋养体含1～2个红细胞。细胞反应较轻。在远离脓肿的肝细胞一般正常,但在一些血管附近,有成簇的滋养体.紧靠这些滋养体的肝细胞已有坏死,提示阿米巴从原发病灶经血道播散,引起继发性病灶,最后与原发病灶融合,形成一个较大的脓肿。
Hamsters were inoculated intrahepatically with 5 strains of Entamoeba histolytica (abbreviation: Eh) to observe the pathological features of amoebiasis. Hamsters produce liver lesions similar to humans. Abscess wall surface irregular, central to varying degrees of liquefaction necrosis. A large number of amoeba trophozoites can be seen between the denatured liver cells and necrotic tissues of the abscess. The size of the amoeba trophozoites is different. Some trophozoites contain 1 to 2 red blood cells. The cell response is lighter. Liver cells away from the abscess are generally normal, but near some blood vessels, there are clusters of trophozoites. The liver cells close to these trophozoites have become necrotic, suggesting that amoeba spreads from the primary lesion through the hematogenous channels, causing secondary The lesions eventually fuse with the primary lesions to form a larger abscess.
