Observations on the pulmonary circulation

Observations on the choroidal circulation.

THE discovery of aqueous veins and subsequent studies of their significance in health and disease have been responsible in no small measure for a new impetus to research work in the aetiology of glaucoma, which in turn has necessitated a re-examination of our fundamental knowledge of the anatomy and physiology of the ocular circulation and the drainage of the aqueous humour, with particular ref...

Further observations on the effect of hydrogen ion on the pulmonary circulation.

Observations on the circulation in the cochlea.

A STUDY of the circulation in the labyrinth, to be complete, must include an investigation of the fluid circulation. The fluid system in the labyrinth is much more complex than that of the cerebrospinal axis. In the latter, the cerebrospinal fluid, produced by the choroid plexuses, circulates by known anatomical pathways and its main function is the protection of the brain. In the labyrinth, ho...

Diabetes and the pulmonary circulation.

DIABETES IS AN EPIDEMIC in the United States, affecting 8% of the population. The hallmark of diabetes is hyperglycemia due to either insulin deficiency or insulin resistance. Systemic vascular dysfunction is a central part of the pathophysiology of both type I insulin-dependent and type II non-insulin-dependent diabetes and involves both the microand macrocirculation (11). Coronary heart disea...

Fulvine and the pulmonary circulation.

The pyrrolizidine alkaloid, fulvine, is now accepted as a major cause of veno-occlusive disease of the liver in the West Indies, where it is ingested as a decoction of the plant Crotalaria fulva in bush tea. Fulvine is similar in chemical structure to monocrotaline, which is known to cause pulmonary hypertension in rats. Thirty young female rats were given a single dose of fulvine either by int...
