    Large-area mosaic diamond films approaching single-crystal quality (1991)

    Notes: The seeding for large-area mosaic diamond films approaching single-crystal quality is described. The technique includes patterned etching of relief structures in Si substrates, deposition from a slurry and orientation of macroscopic diamond seed crystals in the structures, and chemical vapor deposition overgrowth of the diamond seeds to form a continuous film. The film comprises ∼100 μm single crystals, which are separated by low-angle grain boundaries of a few degrees or less. We believe that these low-angle grain boundaries will not affect the electrical properties of majority-carrier devices.

    Notes: Enzyme histochemical studies were made on placental fragments maintained in vitro and insonated for 8 hours with pulsed and continuous wave ultrasound at 2 MHz, and at intensities substantially above those used in clinical apparatus. No difference was observed in the activity of eleven enzymes examined in the insonated fragments compared with a control series.

    EFFECTS OF HISTAMINE BOLUS INJECTIONS AND CONTINUOUS INFUSIONS ON THE H1- AND H2-RECEPTORS IN THE HINDLIMB VESSELS OF THE RABBIT (1977)

    Notes: 1. Hindlimb vascular resistance (HVR) was continuously measured after pharmacological block of the autonomic effectors in unanaesthetized rabbits with previously implanted Doppler ultrasonic flowmeters.2. Histamine bolus injections caused a dose-related short lived fall in HVR followed by a more sustained rise. The fall was due to H2-receptor stimulation (blocked by burimamide or metiamide) and the rise to H1-receptor stimulation (blocked by mepyramine). At the doses of histamine tested the magnitude of the H1-mediated vasocoiistriction had a larger peak effect than the H2-mediated vasodilatation.3. Histamine infusions up to 200 μg kg−1 min−1 did not alter HVR significantly but both increases and decreases in HVR were observed after giving H2- or H1-antagonists, respectively.4. From the double reciprocal plots of 1/peak HVR change and 1/dose of histamine the magnitude of the predicted H1- and H2-mediated peak HVR effects at large doses were the same. This suggested that the number of H1-- and H2-receptors were similar in the hindlimb vascular bed, in agreement with the infusion data.

    INTRARENAL ACTION OF ANGIOTENSIN II IN RESTORING RENAL ARTERY PRESSURE AFTER ACUTE RENAL ARTERY STENOSIS (1978)

    Notes: 1. The renal artery of conscious dogs was acutely narrowed over 30 s to reduce renal artery pressure distal to the stenosis to 40 mmHg and the stenosis was maintained for 1 h. The distal renal artery pressure was rapidly restored to a plateau slightly below pre-stenosis values within 10–15 min. Rises in systemic blood pressure and plasma renin activity were small and transient.2. This restoration was an active process, mediated by the intrarenal effects of angiotensin II (AH), since it was greatly diminished or abolished when the renal artery was narrowed in the presence of angiotensin I-converting enzyme inhibitor or angiotensin receptor antagonist (l-Sar-8-Ue All). However, it was not diminished by ‘total’ autonomic effector blockade.3. This angiotensin II-mediated restoration of renal artery pressure may be of homeostatic significance for the maintenance of glomerular filtration rate.

    THE INFLUENCE OF ALTERATIONS IN THE CARDIAC LOADING CONDITIONS ON INDICES OF MYOCARDIAL CONTRACTILITY IN THE ANAESTHETIZED DOG (1977)

    Notes: 1. An online analogue computer was used to measure myocardial contractility as the ratio dP/dt/IIT where dP/dt is maximum rate of change of left ventricular pressure and IIT is integrated isometric tension.2. In the open thorax anaesthetized dog, max (dP/dt) and dP/dt/IIT were compared during alterations in preload, by partial vena caval occlusion, and changes in after-load obtained by acetylcholine injections and by partial occlusion of the descending thoracic aorta.3. A fall in preload lowered max (dP/dt) but did not alter dP/dt/IIT A rise and fall in afterload produced respectively an increase and decrease in max (dP/dt) but dp/dt/IIT was unaltered.4. From expanded time base recordings, the time from the start of aortic flow (EM flowmeter) to max (dP/dt) was measured to indicate the relationship between valve opening and rnax (dP/dt). At low preload or elevated afterload the aortic valve opened well after max (dP/dt) had been reached. When the afterload fell, max (dP/dt) occurred after the opening of the aortic valve.5. Positive inotropic stimulation following intravenous isoprenaline caused a marked elevation in dP/dt/IIT. However, the rise in max (dP/dt) was attenuated in comparison to dP/dt/IIT by a marked fall in afterload and thus early opening of the aortic valve.6. It is concluded that max (dP/dt) is very sensitive to alterations in preload or afterload but the index——-dP/dt/IIT is normalized so that changes in end diastolic fibre length do not alter this index. When the afterload falls max (dP/dt) is no longer determined in the isovolumic phase of contraction so that magnitude of rnax (dP/dt) is reduced. However, it is an empirical finding that IIT also falls so that the ratio is unaltered. dP/dt/IIT is a useful index of myocardial contractility that is insensitive to changes in preload or afterload.

    ENDOTHELIUM-DEPENDENT RELAXATION IS UNALTERED BY HYPERTENSION, CHOLESTEROL OR INTIMAL THICKENING (1986)

    Notes: 1. The effect of cellophane wrap hypertension (WRAP) and hypercholesterolemia (1% cholesterol diet, CHOL) for 4 weeks was assessed on the endothelium-dependent vasodilator response to acetylcholine in conscious rabbits after pharmacological autonomic blockade.2. Dose-response curves for the hindlimb vascular resistance (ear artery pressure/lower aortic blood flow; Doppler flowmeter) and acetylcholine infusion (i.v.) doses were unaltered in sensitivity (ED50) for any of the treatment groups. The range and slope of the curves were significantly altered by WRAP, CHOL or WRAP plus CHOL for acetylcholine and adenosine infusions consistent with medial hypertrophy in resistance vessels and raised serum viscosity.3. The effect of intimai thickening on the response to endothelium derived relaxing factor (EDRF) was tested in dog carotid artery ring segments in vitro 4 weeks after endothelium removal.4. The relaxation responses to acetylcholine (EDRF-dependent) and adenosine or nitroglycerin were not significantly altered by the neo-intima.5. Therefore the response to EDRF released by acetylcholine in resistance vessels was unaltered by hypertension, hypercholesterolemia or both together. Neo-intimal thickening in response to initial endothelium loss does not appear to alter EDRF responses in the carotid artery.

    ENDOTHELIN IS BLOOD VESSEL SELECTIVE: STUDIES ON A VARIETY OF HUMAN AND DOG VESSELS IN VITRO AND ON REGIONAL BLOOD FLOW IN THE CONSCIOUS RABBIT (1989)

    Notes: 1. Endothelin (Et), a vasoconstrictor peptide, was 5–10-fold more potent (lower EC50) on isolated ring segments of large veins than on large arteries removed from dog coronary, mesenteric, femoral, renal and internal mammary vasculature and from the human internal mammary pedicle.2. In the dog large coronary artery, Et (10–30 nmol/L) caused transient relaxations partway through the generation of a concentration-contraction curve. These relaxations were endothelium dependent.3. In conscious rabbits treated with mecamylamine, Et (0.025–0.4 nmol/kg) caused a marked rise in renal vascular resistance but hindquarter vasodilation. Under the same conditions angiotensin II constricted both beds.4. These studies suggest that Et is vascular bed and large vein selective in activity. It did not appear to be selective for large or small coronary arteries in vitro.
