A surgical procedure was developed for autoplastic grafting of the ovary into the splenic circulation. The ovarian transplant is joined to the spleen by an attached piece of oviduct and uterus. Direct arterial connections to the graft are maintained throughout the procedure; there is no direct contact of splenic and ovarian tissue. Transplantation of the left utero-tubo-ovarian segment and remo...

The neuronal and epithelial parts of the hypothalamo-hypophyseal complex (proximal and distal neurohypophysis, adenohypophysis) have in common the task of message transfer. According to the paraneuron concept, neurons and endocrine cells as paraneurons produce similar or identical substances, store them in vesicles and release them in response to specific stimuli. The released substances reach ...

Conclusions.-A method of resolution of tertiary carbinols of the aromatic series containing an asymmetric carbon atom has been described by means of which an optically active derivative of phenylbiphenyl-anaphthyl carbinol has been prepared. Investigations are now in progress with a view of converting this compound into an optically active triarylmethyl. The results of these experiments will be...
