MOSQUITO TRANSMISSION OF A RETICULUM CELL SARCOMA OF HAMSTERS.

A transplantable reticulum cell sarcoma with leukemic manifestations can be transmitted from one hamster to another by means of a mosquito, Aëdes aegypti (L.). The transmission seems to be by a transfer of tumor cells, and not by passage of some other oncogenic agent.

Milker's nodules: isolation of a poxvirus from a human case.

A virus of the pox group was isolated from a lesion on a patient with milker's nodules by use of tissue cultures of bovine cells. The virus shows marked biologic and serologic differences from vaccinia virus, and it is presumably the etiologic agent of the milker's nodule syndrome.

Structure of the rete mirabile in the kidney of the rat as seen with the electron microscope.

Electron micrographs of the rete mirabile in the medulla of the rat have revealed that the endothelium of the afferent and efferent vessels are markedly different in fine structure. The venous capillaries returning blood from the papilla are lined with a fenestrated endothelium much like that in the peritubular capillaries of the kidney. The arterial capillaries delivering blood to the papilla have an unperforated lining of overlapping endothelial cells with extremely irregular tapered margins. It is pointed out that the organization of particularly the latter vessels suggests that the functional capabilities of these retia go beyond those of a simple diffusion countercurrent exchanger.
