The effects of local intra-arterial infusions of serotonin (5 or 25 micrograms base/min) or norepinephrine (1 or 5 micrograms base/min) on cutaneous (skin) and skeletal muscle vasculatures were investigated in canine forelimbs perfused at constant flow in dogs anesthetized with pentobarbital. Norepinephrine produced dose-related constriction of the skin and skeletal muscle vasculatures. In the ...

BACKGROUND The issue of superiority of single internal thoracic artery grafting versus bilateral internal thoracic artery grafting remains unresolved. The aim of this study was to compare the long-term outcome of single and bilateral internal thoracic artery grafting with concomitant saphenous vein grafting for multivessel coronary artery bypass grafting. METHODS Between March 1985 and April ...

melissa officinalis l. is a medicinal plant with a large variety of pharmacological effects and traditional applications. this study aimed to evaluate the protective and antioxidant activities of the extract of m. officinalis aerial parts on human umbilical vein endothelial cells (huvecs) under oxidative stress induced by h 2 o 2 . cells were incubated with h 2 o 2 (0.5 mm, 2 h) after pretreatm...

In clinical anatomy, the renal venous system is relatively understudied compared to the arterial system. The great complexity of the patterns and inter-relationships of the arteries and veins of the kidney is demonstrated by gross anatomical dissection and clinical practice. This review of several renal vein investigations aims to clarify and update the variable patterns of the renal venous vas...

BACKGROUND Hemodialysis arteriovenous synthetic grafts (AVG) provide high volumetric blood flow rates shortly after surgical placement. However, stenosis often develops at the vein-graft anastomosis contributing to thrombosis and early graft failure. Two novel fusion proteins, ANV-6L15 and TAP-ANV, inhibit the tissue factor/factor VIIa coagulation complex and the factor Xa/factor Va complex, re...

The knowledge of variations in the superficial veins is of clinical importance for the anatomist, radiologists, clinical practitioners and surgeons in order to plan about the operative procedures. Usually cephalic vein drains into the axillary vein. In this case report study the left cephalic vein communicates with the left external jugular vein and made a common trunk at th...

OBJECTIVE The following report describes the experience of the Cardiovascular Surgery Team of the ABC Medical School with coronary-coronary bypass grafting. METHODS Four patients undergone off-pump coronary artery bypass grafting, with coronary-coronary bypass of the right coronary artery, by using great saphenous vein graft. RESULTS The follow-up period was 3 to 5 years without any intra- ...

We report a 31 year old woman presented with three months history of large untreated parapharyngeal abscess and bleeding from the mouth. On evaluation chest CT scan identified the abscess extending down to the superior mediastinum and multiple small lung abscesses. Echocardiography showed tricuspid valve insufficiency. Patient was brought to the operating room (OR) and intra-operatively it was ...

This is a case report of a patient with difficult venous access following thrombosis of major superficial and deep veins of the limbs as documented by ultrasound doppler and venography. The insertion of a few central ports were infected and the vein thrombosed. Venography revealed that central venous access was no longer feasible. The previous laparotomies had resulted in dense intra-peritoneal...

PURPOSE Several MRA techniques have been implemented for non-invasive imaging of the portal vein. A time-spatial labeling inversion pulse (time-SLIP) technique was reported using a free hand spatial selection and tag-on and tag-off alternating scan and MIP processing to only depict the marked blood while canceling the background signals at any specified inversion time [1]. The purpose of this s...
