Computer simulation of cerebral microhemodynamics.

Microvascular network hemodynamics was simulated by computer in an anatomically reconstructed cerebral microvascular network. A video microscope system was used for three-dimensional mapping of the vessel network in the rat brain cortex. The complete topology, length and mean diameter of the microvessels were determined. The distribution of blood flow and red cell flux in the network was calculated based on vessel resistance estimated from geometrical data and a rheological model of blood. This model described apparent relative blood viscosity as a function of vessel diameter and local discharge hematocrit. The calculations predicted highly heterogeneous cell flux distribution at any feed hematocrit between 10 and 40 percent. The frequency distribution of microvessel hematocrit was bimodal and included values exceeding the feed hematocrit value. A probabilistic simulation of cell transit resulted in transit time distributions which agree with experimental findings. The most probable transit time and capillary path length and 4s and 300 microns, respectively.

When the psychotherapist is black.

The authors present a case report of a white neurotic man treated in long-term psychoanalytic therapy by a black woman psychiatrist. The defense mechanism of reversal--the therapist was white in the patient's early dreams--was evident not only in this patient but in several other white patients treated by the black therapist. The authors suggest that, contrary to the opinions of a few other authors, the reality issues of racial differences can be dealt with successfully in this kind of interracial psychotherapy.

Depressive disorders and religious conversions.

The sparse psychiatric literature concerning religious conversions is reviewed. Four case histories of diagnosed depressive illness followed by religious conversion are presented. In two obsessive-compulsive patients, the religious experience failed to resolve the depression, and both ended in suicide. Two hysterical personalities had a resolution of depressive symptoms following the religious experience. The authors suggest that religious conversion dynamically strengthens repression in hysterical persons, but in some cases fails to resolve obsessive isolation of affect and ambivalence.

Autofellatio: a power and dependency conflict.

The literature concerning autofellatio is reviewed, and two additional cases are reported. A third case of a neurotic patient in whom there was a reversal of an autofellatio fantasy is presented. These cases seem to involve narcissism, dependency, and power conflicts as have those cases previously reported in the literature.
