Ultrastructural arguments for cytoplasmic engulfment phenomenon in nucleus of Entamoeba histolytica.

The electron optic study of a pathogenic E. histolytica strain revealed particular aspects concerning the shape, structure and distribution in the nuclear space of the intranuclear structures known as button-like bodies. These aspects are ultrastructural arguments useful in interpreting the intranuclear inclusions as sections through the cytoplasmic material sequestered in the nuclear space by karyophagocytosis.

[Cholangiocholecystitis, an acute attack with acarids in B bile].

The present paper reports on an acute febrile attack in a patient suffering from chronic non-lithiasis cholecystitis. Acarids and acarid eggs in various stages of development were found in bile B following duodenal intubation in the course of the attack. The administration of magnesium sulphate was followed by abundant biliary vomiting.
