After microsurgical dissection of the thoracic aorta of normotensive rats, biochemical and morphological comparisons were performed between the intima-media and adventitia. The DNA content, wet weight, and dry defatted weight of the adventitia were half that of the intima-media. Collagen was the main component of the adventitia (collagen greater than nonfibrous protein greater than elastin) whe...

A reliable liver metastasis model using intraportal injections of sarcoma cells was established in syngeneic hooded Lister rats to study the blood supply of the tumours and to evaluate the role of degradable starch microspheres (DSM) in conjunction with selective hepatic arterial and portal venous chemotherapy. The tumour/normal liver (T/L) ratio after intra-arterial and intraportal injection o...

Cerebral Blood Flow, Metabolism and Mean Arterial Pressure Changes Following Unilateral Internal Carotid Endarterectomy: Cerebral Ischemia and Elevated Systemic Arterial Pressure • Cerebral blood flow and metabolism studies were performed on 13 patients before and after unilateral carotid endarterectomy for severe atheromatous occlusive disease. Mean brachial arterial pressure was monitored dur...

conclusions the ligation method with attention to the modifications described further in the article is a simple, safe and cost effective option for the management of urethral prolapse.rnmaintaining the inflated balloon of the foley catheter with timed catheter removal especially adds predictability to this technique. results the mean age of the patients was 6 years old (ranging from 3 to 8 yea...

INTRODUCTION Placenta accreta is an increasingly common complication of pregnancy that can result in massive hemorrhage. CASE PRESENTATION We describe two cases of placenta accreta, with successful conservative management in a referral hospital in Tehran, Iran. In both cases, two procedures were performed: compression suture (B-Lynch) and a perfusion-decreasing procedure (bilateral uterine ar...

BACKGROUND Hemorrhoid laser procedure is a new laser procedure for outpatient treatment of hemorrhoids in which hemorrhoidal arterial flow feeding the hemorrhoidal plexus is stopped by means of Doppler-guided laser coagulation. OBJECTIVE Our aim was to compare the hemorrhoid laser procedure with rubber band ligation for outpatient treatment of symptomatic hemorrhoids with moderate mucosal pro...

To test the hypothesis that nitric oxide (NO) production is essential for endogenous vascular remodeling in ischemic skeletal muscle, 22 New Zealand White rabbits were chronically instrumented with transit-time flow probes on the common iliac arteries and underwent femoral ligation to produce unilateral hindlimb ischemia. Iliac blood flow and arterial pressure were recorded at rest and during a...
