STUDIES ON THE PINEAL GLAND

Studies on Tumor Metastasis Vii. Metastasis to the Pineal Gland

Reports of tumor metastasis to the pineal gland are exceptionally rare, perhaps because of little systematic post-mortem study. Primary tumors are apparently much more frequent and have been carefully studied (1). The first instance of metastasis is that reported by Forster (2) of Gottingen in 1858. The patient was a thirty-seven-year-old male with cancer of the lung (possibly esophagus) and wi...

The Pineal Gland

mied nearly in tbe center of the B brain in any mammal is a small white structure, sbaped somewhat like a pinecone, called tbe pineal body. ln man this organ is rougbly a quarter of an inch long and weighs about a tenth of a gram. The function of tbe pineal body has never been clearly understood. Now that tbe role of tbe tbymus gland in establishing tbe body’s immunological defenses bas been de...

The pineal gland.

The antisteroid action on the pineal gland.

The study presents the data gathered along the years on the antisteroid action of the pineal gland. Thus, it was demonstrated that administration of pineal polypeptides to the rabbit lowers the urinary 17-KS both of testicular and adrenal origin. Conversely, pinealectomy caused an increase in the level of these steroid hormones. The same pineal material induced a marked decrease both in the ser...

Biorhythms and pineal gland.

Endocrine biorhythms are classified according to the period time, as one of the most characteristic properties of biorhythms. Each endocrine organ has parallel more than one biorhythms with different period time (e. g. circadian and circannual rhythms). The time of acrophase of the biorhythms at the different endocrine organs is fairly variant. This review summarizes the rhythmic function of th...
