The Digital Circulation in Peripheral Vascular Diseases.

Experimental and clinical evaluation in man of hexamethonium (C6), a new ganglionic blocking agent.

In man, C6, a new ganglionic blocking agent (50 mg. intravenously) produced inhibition of the Valsalva, tiltback and cold pressor vasopressor responses. Marked increases in digital blood flow and skin temperature with inhibition of digital reflexes to "noxious" stimuli were consistently observed (room temperature 70 F.). The increase in skin temperature was greater and more lasting than followi...

Arteriographic Evaluation of Laminitis Digits in the Hind Limbs of Dairy Cattle

Objective: Laminitis is one of the main causes of lameness in dairy cattle. In this situation the corium blood circulation is disrupted and the production of healthy horny hoof wall is reduced. The purpose of this study was to evaluate the arteriographic pattern of the digital arterial branches in the laminitic digits and to compare them with the normal digits. Design: Original study. Animals...

Digital Hemodynamics in the Normotensive and Hypertensive States. Ii. Venomotor Tone.

T HE single factor implicit in the sustained hypertensive state, regardless of etiology, is an increase in peripheral vascular resistance. It is generally agreed that this results from a narrowing of the small arteries and arterioles. Although the small veins and venules possess anatomically and physiologically similar smooth-muscle elements, they have not been implicated in this increase in va...

The basis of Fluorescing Angiography and Its Diagnostic Significance in Vascular Diseases

Fluoresing photography has become a prominent branch in opthalmology. During the last few years, it gives us dynamic infor-of circulation of the EYE and its pathologieal disorders.By passing the fluoresein through the retinal and choroidal vessels we are able to record the different typesand stages of disease which these are not exactly diagno-sed by ophthalmoscopy and founds photography.By flu...
