Membrane traffic at the hepatocyte's sinusoidal and canalicular surface domains

W. Howard Evans – 1 September 1981 – Traffic in the environs of regions of the hepatocyte's plasma membrane is heavy. A fuller understanding of the nature and control of this membrane traffic depends on the appreciation of the hepatocyte's plasma membrane. This conglomerate consists of a receptor‐rich and metabolically dynamic blood‐sinusoidal domain which is separated from the bile canalicular domain by a lateral domain which participates in cell‐cell interactions (1, 2).

Acute effects of ethanol on hepatic uptake and distribution of narcotics in the isolated perfused rabbit liver

Mary Jeanne Kreek, Marcus A. Rothschild, Murray Oratz, Joseph Mongelli, Anne C. Handley – 1 September 1981 – This study was performed as an initial step in systematically defining the hepatic interactions between ethanol and opioids using a controlled in vitro system. The acute effects of ethanol on the initial uptake and distribution of long‐ and short‐acting narcotics were studied using isolated rabbit liver perfused with rabbit blood without or with ethanol.

The hepatocellular uptake and biliary excretion of endotoxin in the rat

Shyamal K. Maitra, Daniel Rachmilewitz, David Eberle, Neil Kaplowitz – 1 September 1981 – Endotoxin is known to cause a dose‐dependent impairment of hepatic bile secretion, organic anion excretion, and activity of Na+, K+‐activated ATPase. Since it is possible that this impaired excretory function is a result of direct interaction of endotoxin with hepatocytes, we examined: (a) the excretion of endotoxin into bile, and (b) its association with an hepatocyte‐enriched, Kupffer cell‐depleted population of liver cells.

Hepatocyte and Kupffer cell functions during liver regeneration in streptozotocin‐diabetic rats

Robert P. Cornell, Brenda K. Hinck, Randall E. Halley – 1 September 1981 – The insulinoprivic influence of acute severe streptozotocin diabetes on liver regeneration in rats was evaluated by determining liver weights as well as hepatocyte and Kupffer cell functional capacities. Functional capacities were assessed by bromosulfophthalein uptake for hepatocytes and carbon phagocytosis for Kupffer cells.

Electron microscopic studies of Dane particles in hepatocytes with special reference to intracellular development of Dane particles and their relation with HBeAg in serum

Tomoteru Kamimura, Akira Yoshikawa, Fumihiro Ichida, Hiroshi Sasaki – 1 September 1981 – Electron microscopic observations in 30 cases of HBsAg positive liver disease and 12 asymptomatic carriers of HBsAg suggested the following mechanism of intracellular development of Dane particles: core particles migrated from the nucleus into the cytoplasm through the nuclear pores. Intracytoplasmic core particles protruded into the cisternae of endoplasmic reticulum by budding the outer coat of Dane particles being derived from the membrane of endoplasmic reticulum.
