Pineal gland metastases from mammary carcinoma.

Breast carcinomas often metastasize into various organs, most commonly into the lung and rather infrequently into the pineal gland. There were only 20 cases of the latter recorded until 1950. Currently, the total number of reported cases, including this report, is 74.

Cardioprotective action of sodium gamma-hydroxybutyrate against isoproterenol induced myocardial damage.

In this study, the effects of graded doses of isoproterenol (IP) on the heart were examined in untreated gerbils and in gerbils anaesthetized with gamma-hydroxybutyrate (GHB), an endogenous metabolite with energy sparing properties. We were interested in the cardioprotective potential of GHB. IP was administered intraperitoneally in doses of 0.

Why the incidence of cancer is increasing: the role of 'light pollution'.

At present, cancer is responsible for almost half of all deaths among women 45-64 years of age, and about 30% of all deaths among men in the same age group (1). This high rate represents a marked increase from the end of the last century (2), and it probably has a multifactorial etiology. Air pollution, smoking, diet, alcohol, occupational exposures and stress are all considered as possible etiologic and risk factors (3).

Oncostatic effects of the pineal gland.

There is increasing evidence that the pineal gland has a role in the control of neoplastic processes. Kerenyi found hyperplasia of the pineal gland in patients with widely disseminated malignant melanoma. Feuer and Kerenyi reported significantly higher serum melatonin levels with malignant melanoma.
