Liver disease in children with pizz α1‐antitrypsin deficiency

Fayez K. Ghishan, Harry L. Greene – 1 March 1988 – We present our experience with 18 pediatric patients with α1‐antitrypsin deficiency of the PiZZ phenotype. Fifteen patients (83%) presented with neonatal cholestatic jaundice at a mean age of 2 ± 0.6 months (±S.D.). The male:female ratio was 15:3, indicating a male predominance. All metabolic, infectious and obstructive causes of jaundice were ruled out by appropriate tests in the patients with neonatal cholestasis.

Determination of parameters effecting proton relaxation of hepatic and gallbladder biles in dogs

Douglas A. Bakan, James L. Barnhart – 1 March 1988 – The parameters which are important in causing changes in the Tl and T2 proton magnetic relaxation times of dog bile were investigated. Three factors were found to be important in causing relaxation in bile: (i) total bile salt concentration; (ii) total protein concentration, and (iii) viscosity. The T1 and T2 values of hepatic and gallbladder biles were found to be independent of specific gravity, osmolarity and electrolyte concentrations.

Elevation of acetylpolyamine levels in mouse tissues, serum and urine after treatment with radical‐producing drugs and lipopolysaccharide

Hiroyuki Sugimoto, Shoji Yamada, Takayuki Arai, Setsuo Kobayashi, Koei Hamana, Shigeru Matsuzaki – 1 March 1988 – Polyamines and acetylpolyamines were analyzed in the liver, spleen, lung, kidney, serum and urine by high‐performance liquid chromatography on a column of cation‐exchange resin after administering various cytotoxic substances to male mice. All of the compounds tested more or less affected the tissue levels of polyamines, including putrescine, spermidine, spermine and acetylpolyamines (N1‐acetylspermidine and N1‐acetylspermine).

Changes in albumin, α‐fetoprotein and collagen gene transcription in ccl4‐induced hepatic fibrosis

Arturo Panduro, Fouad Shalaby, Luis Biempica, David A. Shafritz – 1 March 1988 – In efforts to understand mechanisms of liver dysfunction in cirrhosis, transcription of specific genes important to liver function has been measured in the rat model of CCl4‐induced hepatic fibrosis. The relative transcription rates of albumin, α‐fetoprotein and pro‐α1‐collagen genes were studied during development of fibrosis and after fibrosis was established.

Plasma levels of pipecolic acid in patients with chronic liver disease

Hironaka Kawasaki, Tatsuaki Hori, Masako Nakajima, Kenzo Takeshita – 1 March 1988 – Plasma levels of pipecolic acid, which is a minor metabolite of lysine, were determined by high‐performance liquid chromatography in 22 patients with chronic liver disease, composed of 6 patients with chronic active hepatitis, 11 with liver cirrhosis and 5 with hepatocellular carcinoma.

Vitamin a hepatotoxicity in multiple family members

Gerald Y. Minuk, James K. Kelly, Wei‐Sek Hwang – 1 March 1988 – Three of five family members experienced symptoms and biochemical evidence of hepatitis that could not be explained on the basis of infectious, metabolic or immunologic disorders of the liver. A history of prolonged ingestion of moderate amounts of vitamin A (20,000 to 45,000 IU per day for 7 to 10 years) was obtained in each of the three family members and was absent in the remaining two unaffected individuals. A liver biopsy performed in one family member confirmed the diagnosis of vitamin A toxicity.

Effect of vasodilators on hepatic microcirculation: A study of the inhibition of norepinephrine‐induced vasoconstriction in the isolated perfused rat liver

Philippe Marteau, François Ballet, Yves Chrétien, Colette Rey, Patrice Jaillon, Raoul Poupon – 1 March 1988 – We studied the effects of a series of 16 vasodilators on the intrahepatic vasoconstriction induced by norepinephrine in the isolated perfused rat liver.

Hepatic manifestations of total parenteral nutrition: Need for prospective investigation

K. N. Jeejeebhoy – 1 March 1988 – Total parenteral nutrition is now widely used in the treatment of nutritional depletion. Among problems that persist in the use of this technique, the development of hepatic abnormalities has received increasing attention. In this review, the current understanding of the pathogenesis and management of liver injury during short‐term total parenteral nutrition is summarized. These complications include fatty liver, cholestasis, and nonspecific triaditis. The experience with hepatic complications during long‐term total parenteral nutrition is also reviewed.

Selenium deficiency in search of a disease

Raymond F. Burk – 1 March 1988 – Serum selenium concentrations were found to be significantly lower in women with intrahepatic cholestasis of pregnancy than in women with normal pregnancies during the last trimester of pregnancy and post partum. The activity of the seleno‐enzyme glutathione peroxidase had a significant positive correlation with selenium concentration and it was also significantly lower in women with the disease.
