Quantitative Studies with MH2 Reticulo Endothelioma Virus

Intravascular Endothelioma (endothelioma in Situ, Systemic Endotheliomatosis).

A woman aged 48 years was found to be suffering from intravascular endothelioma. The initial clinical presentation was the presence of red, painless swellings in the skin of the lower limbs. The other clinical features, and the histological changes in skin biopsies, are described and compared with those in the two previously reported patients. It is suggested that the condition is analogous to ...

Quantitative studies on meningopneumonitis virus.

Using dialyzed allantoic fluid suspensions of meningopneumonitis virus, Crocker (1954) studied the ratio of numbers of virus particles, as determined by electron microscopy, to egg infectivity. He reported the number of particles per egg LDso to vary from 200 to 1000. Zahler and Moulder (1953) used the method of Gogolak (1953), in which stained virus particles are counted by light microscopy, t...

Quantitative Studies on the Neutralization Reaction between African Horse-sickness Virus and Antiserum

Endothelioma of the optic nerve.

Examination.-She was a fit woman at the time of her visit, with a blind left eye (no perception of light), and a typical enlarged amaurotic pupil. The right eye was normal. The left fundus showed a chalky white papilla with ? glial overgrowth at its lower half. The retinal vessels were seen to arch with this glial tissue and to dip to the fundus level at its border. All vessels-arteries as well...

“endothelioma” of the Pleura

Perhaps as much because of the confusing character of the clinical phenomena, as of the rather striking appearances revealed after death, supposed primary malignant tumors of the pleurae have consistently appealed to medical writers as worthy of study and report. Further stimulus to investigation of this somewhat peculiar group has been furnished by the clearly apparent wide diversity of concep...
