To the Editor.— Hansen and co-workers1 have taken the time to address a question of considerable import, ie, whether the use of Doppler continuous wave forms provides a means of reflecting changes in brain blood flow when the anterior cerebral artery is used.

1. The intramural blood vessels of the human colon have been described. 2. Five methods that have been used to study colonic mucosal blood flow in patients with colostomies or with normal colons were briefly outlined along with some of the limitations of each technic. 3.

Hence does arise the action and function of the heart, which by pulsation it performs. [William Harvey, De Motu Cordis, 1628.] THE study of blood flow as a pulsatile phenomenon is scarcely new, but it has gained new impetus from three recent developments: the commercial production of reliable blood flowmeters, the formulation of theories appropriate to

In ophthalmology, laser-Doppler velocimetry (LDV) has been used for various types of measurements besides those of blood velocity. For example, it has been applied to investigate eye motion during smooth pursuit of a target [1] and the mechanical compliance of the optic nerve head [2].

Multi-scale modeling of arterial blood flow can shed light on the interaction between events happening at micro- and meso-scales (i.e., adhesion of red blood cells to the arterial wall, clot formation) and at macro-scales (i.e., change in flow patterns due to the clot).

The direction of pituitary blood flow, the amount of pituitary blood flow, its regional control, and the role of the median eminence microcirculation are the subjects of this review. Present concepts of pituitary blood flow are focused almost entirely on its direction and arouse from studies of pituitary vascular anatomy performed almost 50 years ago ...

The pressure-flow relationship of the choroidal circulation of the cat was studied by the Krypton clathrate Kr 85 desaturation technique. At intraocular pressures below 20 mm Hg, the choroidal circulation was found to behave like a passive vascular bed; above 30 mm Hg, it was found to behave like an active bed with a mild degree of autoregulation.

Blood is the fluid which flows in the cardiovascular system. It is, however, not a pure fluid but rather a suspension of a number of different particles (cells, cell fragments and macromolecules) in a fluid base. This chapter explores the fluid behaviour of blood including the impact of the particles on this behaviour.
