Three‐dimensional observations of the hepatic arterial terminations in rat, hamster and human liver by scanning electron microscopy of microvascular casts

Kazuhide Yamamoto, Igor Sherman, M. James Phillips, Murray M. Fisher – 1 May 1985 – The arterial terminations were studied by scanning electron microscopy of microvascular casts in rat, hamster and human livers. Important species differences were observed. In the rat, frequent anastomoses between the terminal hepatic arterioles and portal venules were observed, whereas a few arterioles terminated directly into sinusoids. On the contrary, no arterioportal venous anastomoses were demonstrated in the hamster and human livers.

Comparison of the phenacetin and aminopyrine breath tests: Effect of liver disease, inducers and cobaltous chloride

Dale A. Schoeller, Alvin N. Kotake, George H. Lambert, Patricia S. Krager, Alfred L. Baker – 1 March 1985 – The phenacetin breath test (PBT) has been proposed as an alternative to the aminopyrine breath test (ABT) for the assessment of hepatic function. To investigate the clinical utility of the PBT, we compared the PBT with the ABT in 9 healthy subjects and 18 patients with biopsy‐proven liver disease.

Aldehyde dehydrogenase in alcoholic subjects

Kelvin R. Palmer, William J. Jenkins – 1 March 1985 – Hepatic aldehyde dehydrogenase activity is depressed in alcoholic liver disease and may account for the observation that alcoholics develop high blood acetaldehyde concentrations following ethanol. To determine whether this is a specific defect in alcoholics, aldehyde dehydrogenase was studied in liver tissue obtained from three groups of subjects.

Androgen and estrogen response to adrenal and gonadal stimulation in idiopathic hemochromatosis: Evidence for decreased estrogen formation

Hans K. Kley, Wolfgang Stremmel, Claus Niederau, Rainer Hehrmann, Omar Shams, Georg Strohmeyer, Hans L. Krüskemper – 1 March 1985 – Gonadal function in idiopathic hemochromatosis (IHC) was evaluated by comparing clinical features and levels of sex hormones in 10 male patients with IHC (cirrhosis, 4; fibrosis, 6), 6 male patients with alcoholic cirrhosis (AC) and 10 healthy, age‐matched controls. Impotence was present in 9 IHC and all AC patients and was associated with decreased plasma testosterone levels.

Therapeutic efficacy of glucan in a murine model of hepatic metastatic disease

David L. Williams, Edward R. Sherwood, Rose B. McNamee, Ernest L. Jones, Nicholas R. Di Luzio – 1 March 1985 – Glucan, a particulate β‐1,3‐polyglucose immunomodulator, was evaluated for its ability to modify hepatic metastases and survival in mice with reticulum cell sarcoma. Sarcoma M5076 cells were injected subcutaneously (1 × 105 cells) into syngeneic C57BL/6J male mice. On Day 20, histopathological studies indicated the presence of hepatic micrometastases. At this time, glucan (0.45 mg per mouse) or dextrose was administered intravenously.

Experimental laser phototherapy of the morris 7777 hepatoma in the rat

Stephen Holt, John Tulip, Douglas Hamilton, Judith Cummins, Anthony Fields, Catherine Dick – 1 March 1985 – The tumoricidal effect of the activation of hematoporphyrin derivative (HpD), by an argon‐ion‐dye‐laser (wavelength 630 nm), was investigated in the Buffalo rat bearing subcutaneous implants of the Morris 7777 hepatoma. Tumor growth was monitored by measuring the tumor volume with constant force callipers. In control animals and those that were pretreated with HpD alone (10 or 20 mg per kg by i.p.
