[The development of microangiopathic hemolytic anemia in the model of a transplantable hemangioendothelioma of the J 129 mouse (author's transl)].

INTRODUCTION: In earlier reports we have described the morphological findings of microangiopathic hemolytic anemia (MHA) in autopsy cases. The aim of this publication is to show more exactly the close correlation between microangiopathy and intravascular hemolysis in a transplantable hemangioendothelioma of the mouse. This animal model is suitable for study of the MHA, which develops within short time, with various morphological and biochemical parameters. MATERIAL AND METHODS: 100 J 129 mice (Jackson Laboratory, Bar Harbor, Me) with transplanted hemangioendothelioma and 20 healthy controls were studied. For transplantation the tumors were removed in toto from donors and mined in 0.9% sterile saline; 0.7 ml of this tumor suspension was injected subcutaneously in the lateral flank of the recipients...

Transformations of consciousness. A cartography. I. The perception-hallucination continuum.

Self-awareness emerges from the evolutionary transformation of material structures into magical, mythical and mental structures of consciousness. Western varieties of conscious states may be mapped on a perception-hallucination continuum of increasing ergotropic or hyper-arousal. These levels of subcortical arousal are cortically or cognitively interpreted as normal, creative, hyperhrenic, cataleptic and ecstatic states. During increasing hyper-arousal (characterized by EEG desynchronization): (1) the variability of the EEG amplitude decreases in introverts whereas in extroverts, it increases; (2) exteroception is transformed into an experience of interoception, while willed motor activity becomes increasingly impaired and ultimately inhibited, and (3) information processing during these hallucinatory states is preferentially shifted from the speech dominant and motor-coordinating or "major" toward the nonverbal, gestalt-perceiving, the non-dominant or "minor" cortical hemisphere.
