The aim of this study was to assess the influence of atrial natriuretic factor (ANF) on arterial baroreflex chronotropic responses and to investigate whether this effect of ANF is affected by angiotensin converting enzyme inhibition (CEI). For this purpose, in 13 normal volunteers, the reflex chronotropic responses to arterial baroreceptor stimulation (phenylephrine, 25-100 micrograms i.v.) or ...

Tearing mode stability analysis in the presence of circulating energetic ions (CEI) is studied in the reversed field pinch (RFP) magnetic configuration. In contrast to the minimal effect of precessional drift of CEI on tearing modes in tokamaks, the effect of precessional drift of CEI on tearing modes is important in the RFP. It is found that the effects of CEI on tearing modes in RFP depend on...

In this study, a semi-quantitative occupational chemical exposure risk prediction model, based on the calculation of exposure hazard indexes, was proposed, corrected, and applied to a national chemical exposure databank. The model comprises one factor used to describe toxicity (i.e., the toxicity index), and two factors used to reflect the exposure potential (i.e., the exposure index and protec...

Urinary kallikrein excretion (UKE) is decreased in rats with passive Heymann nephritis (PHN), but increases after converting enzyme inhibition (CEI). Although CEI potentiates bradykinin activity, neither the effect of CEI on kallikrein secretion nor the abnormal renal kallikrein metabolism in PHN has been examined previously. To determine the mechanism by which CEI increases UKE, normal rats an...

Converting enzyme inhibitor (CEI) produced a greater fall in blood pressure (BP) than the competitive antagonist of angiotensin II, sarcosine-alanine angiotensin II (saralasin), when administered to saltdepleted rats; there was no difference in BP response in salt-loaded rats. Thus, two widely used methods of inhibiting the renin-angiotensin system give discrepant effects. The renin-angiotensin...

Patients with normalor high-renin non-modulating essential hypertension fail to shift their adrenal sensitivity on a low sodium diet in response to an infusion of angiotensin II (Ang II). In a prior study, 72 hours of converting enzyme inhibition (CEI) partially corrected this subnormal aldosterone response to Ang II hi patients with non-modulating hypertension. Since it was uncertain whether t...
