In the Stenotic presence of hem odynam ically sufficient unilateral renal artery kidney stenosis, the kidney distal to the stenosis is rendered ischem ic, activating the renin angiotensin system , and producing high levels of angiotensin II, causing a “vasoconstrictor” type of hypertension.

This failure of “unclipping” to lower the blood pressure in this chronic phase (III) of 2K,1C hypertension is due to FIGURE 3-10 widespread arteriolar damage to the “contralateral kidney,” conse- Sequential phases in two-kidney, one-clip (2K,1C) experimental reno- quent to prolonged exposure to high blood pressure and high levels vascular hypertension.

During this the kidney ipsilateral to the renal artery stenosis are rarely observed transition phase (phase II), salt and water retention are observed as in patients with a long duration (ie, >5 years) of hypertension. The discussion so far of the pathophysiology of renovascular hypertension has focused on the two-kidney, one-clip m odel of renovascular hypertension (“two-kidney hypertension”), wherein the artery to the “contralateral kidney” is patent and the “contralateral” nonaffected kidney is present. Elevated peripheral renin activity, norm al plasm a volum e, and hypokalem ia are typically associated with the elevated arterial pressure. There is another type of “reno- Blood Renin Volume Blood Renin Volume vascular hypertension” known as “one-kidney” hypertension, pressure pressure wherein in the experim ental m odel, one renal artery is constricted High Normal Normal High and the contralateral kidney is removed. Although there is an initial increase in renin release responsible for the early rise in blood pressure in “one-kidney” hypertension as in “two-kidney” hypertension, the absence of an unclipped contralateral kidney allows for sodium retention early in the course of this one-kidney, one-clip (1K,1C) m odel.

HS&DR programme The Health Services and Delivery Research (HS&DR) programme, part of the National Institute for Health Research (NIHR), was established to fund a broad range of research. It combines the strengths and contributions of two previous NIHR research programmes: the Health Services Research (HSR) programme and the Service Delivery and Organisation (SDO) programme, which were merged in January 2012. The HS&DR programme aims to produce rigorous and relevant evidence on the quality, access and organisation of health services including costs and outcomes, as well as research on implementation. The programme will enhance the strategic focus on research that matters to the NHS and is keen to support ambitious evaluative research to improve health services.

The number of clusters is a mea- made by investigators, not a movement made by animals or sure of the relative potency of the positive and negative people. The somatic nervous system controls the oromotor feedbacks (1,17). The meal ends when the animal no longer movements of eating; the autonomic nervous system con- reinitiates licking for a relatively long time (15 to 120 min- trols movements of the digestive tract through its effects on utes in the rat). The sensory effects: First, the site of action of the adequate stimuli is stimuli from these efferent effects are integrated in the cen- preabsorptive. In addition to its classic motor and secretory tral nervous system to affect somatic and visceral efferent functions, the gastrointestinal tract is a sensory sheet from output. The major advance in the understanding of this the tip of the tongue to the end of small intestine. Eating consists of rhythmic oromotor movements, such as licking, lapping, and mastication. For example, rats make five to eight licks per second (the range in individual rats is less). This is the motor signature of a group of neurons acting as a cpg. The cpg for licking in the rat is in the medial, interme- diate, and lateral reticular formation of the medulla (10). A network of premotor neurons extends forward from the caudal brainstem to the region of the substantia nigra (11). Thus, the neural control of eating can be reduced to what turns the cpg on and off (12). Eating can be initiated by a variety of external stimuli, such as visual, social, olfactory, and auditory. Internal stim- uli, such as a slight decrease in plasma glucose (13), a rise in liver temperature (14), and a decrease in basal metabolism (15) are also effective. The efficacy of most, if not all, of these stimuli can be modified by experience. This depicts the temporal interaction of positive to note that the adequate stimuli for the initiation of eating and negative afferent feedbacks produced by ingested carbohy- do not determine the duration or size of the subsequent drate solutions during a representative meal.

Because the cau- dal brainstem contains the cpg and all of the projections of the afferent nerves mediating peripheral feedback effects, the decerebrate rat responds to direct controls (18,19). In contrast, none of the indirect controls that have been tested affect eating in the chronic decerebrate rat. Because indirect controls require the forebrain to be connected to the caudal brainstem in order to control eating, the reciprocal connec- tions between forebrain and hindbrain are necessary for the modulation of the direct controls by the indirect controls. This theory asserts that indirect controls have no direct ac- tion on the cpg during a meal in the absence of direct con- FIGURE 115.
