BACKGROUND/AIMS Although the interlobar arterial collateral of the liver has been thoroughly analyzed, few reports have described the intersegmental arterial collateral between the medial and left lateral segments. METHODS The hepatic arterial system of the left liver was evaluated using 12 latex resin cast specimens in which latex resin was injected into the left hepatic artery after ligatio...

On the supposition that pericoronary lymphatics play an important role in the efflux of interstitial fluid from the blood vessel wall, we examined the morphology of pericoronary arterial lymphatics in the dog. After ligation of the principal epicardial drainage lymphatics, after ligation of the left anterior descending coronary artery, after induced pericoronary inflammation and after instillat...

We developed a new model to examine the role of arterial baroreceptors in the long-term control of mean arterial pressure (MAP) in dogs. Baroreceptors in the aortic arch and one carotid sinus were denervated, and catheters were implanted in the descending aorta and common carotid arteries. MAP and carotid sinus pressure (CSP) averaged 104 +/- 2 and 102 +/- 2 mmHg (means +/- 1 SE), respectively,...

The effect of pyridostigmine (PYR)--an acetylcholinesterase inhibitor--on hemodynamics and cardiac autonomic control, was never studied in conscious myocardial infarcted mice. Telemetry transmitters were implanted into the carotid artery under isoflurane anesthesia. Seven to ten days after recovery from the surgery, basal arterial pressure and heart rate were recorded, while parasympathetic and...

conclusions: the effects of propofol on hemodynamics and arterial oxygen pressure during one- or two-lung ventilation were not different from those of isoflurane. results: sixty patients (mean age = 4124.18 ± 18.63 years) were divided into two groups. the age and gender of the subjects were not statistically different between the two groups. in the propofol group, the arterial oxygen pressure d...

OBJECTIVE In this study, we characterized the effects of an osteopontin (OPN)-null mutation in normal arterial function and remodeling in a murine model. METHODS AND RESULTS OPN-null mutant mice were compared with wild-type mice before and after carotid artery ligation. Before ligation, OPN-null mice had increased heart rate, lower blood pressure, and increased circulating lymphocytes compare...

Bilateral carotid artery ligation was made in 14 SHR while rCBF was serially measured with hydrogen clearance. Blood pressure was controlled with an intra-arterial catheter connected to a reservoir. There was no significant correlation between blood pressure and rCBF prior to the carotid occlusion, but afterwards there was a progressively increasingly negative correlation between mean arterial ...

OBJECTIVE Proliferation and migration of vascular smooth muscle cells (SMCs) are central for arterial diseases including atherosclerosis and restenosis. We hypothesized that the underlying mechanisms may be modeled by carotid ligation in mice. In FVB/N inbred mice, ligation leads to abundant neointima formation with proliferating media-derived SMCs, whereas in C57BL/6 mice hardly any neointima ...

The present study investigated the phytochemical, total flavonoid and phenolic content, antibacterial activity, acute toxicity studies, hemodynamic parameters, myeloperoxidase activity of ethanolic extract Microdus brasiliensis its effects on cecal ligation puncture induced sepsis in mice. preliminary phytochemical screening showed that contains alkaloids, terpenoids, flavonoids, phenolics, sap...
