Anatomic Considerations of the Normal Portal Circulation

صحت تشخیصی پارامترهای شریان کبدی و ورید پورت در داپلر سونوگرافی سیروز

Background: Cirrhosis and portal hypertension influence the hepatic circulation. The purpose of this study was to evaluate the diagnostic accuracy of liver Doppler ultrasonography parameters in cirrhosis.Methods: This case-control study involved 118 subjects. All case subjects had biopsy-proven hepatic cirrhosis. The controls were healthy people, case-matched for age and gender. All cases and c...

Exploitation of bile acid transport systems in prodrug design.

The enterohepatic circulation of bile acids is one of the most efficient recycling routes in the human body. It is a complex process involving numerous transport proteins, which serve to transport bile acids from the small intestine into portal circulation, from the portal circulation into the hepatocyte, from the hepatocyte into the bile, and from the gall bladder to the small intestine. The t...

The Etiology of Neonatal Hyperbilirubinemia

Etiology of Physiologic Neonatal Hyperbili­rubinemia. Every newborn infant develop·s hyperbilirubinemia during the first week of life which is called "physiologic". There are several factors responsible for the development of physiologic hyperbilirubinemia, as follows:  1. Increased bilirubin production, due to a - Increased blood volume. b - Decreased R.B.C. survival time.  c - Increased in...

Absorption studies using portal anastomotic veins.

In man the portal circulation, being without major and macroscopic connection with systemic veins, has been hidden from the clinical investigator. Even the intravascular catheter has not invaded the duplex circulations feeding the liver, but only its drainage system. Thus circulatory inaccessability of the key digestive gland in man has left it mysterious, a metabolic sphinx. Surgeons, deleting...
