Comparisonof nepatomalCarcinogenesiswith Normal Adult and Foetal Hepatocytesin Rats C.G.Schu1r.e , U.N.Riede", K.Joh*‘* Departmentsof Surgery and Pathology**,Univ. of Freiburg, Sundgauallee 45, D-7800 Freiburg,West Germany; Nishi ShinbashiUniversityof Tokyo**', Japan. A quantitativeultrastructuralanalysis wes made of chemically-induced Morris hepatomas in ratS to compare the carcinogenesisof hepatomas with both normal and foetal liver tissue. 20 animals each of 4 differentgradings of Morris hepatomaswere compared with the seme number of normal adult and foetal rats. Our findings showed that although each type of hepatoma has a characteristiccytoarchitecture,all hepatomasshow a varying degree of differentiation dependingon their growth rate. Whereas the rough endoplasmicreticulum in hepatoma cells hardly changed in comparisonto the control hepatocytes, the smcoth endoplasmicreticulumand percxisome values drop considerablyin all hepatoma cells examined (p ( 0.01). Runour-specificmorphometric changes "c:ur in the mitochondria:In comparisonto adult liver cells, the chondriomaof turnourcells comprise a larger number of smaller mitocnondria, the amount of christaemembrane per cell decreasing with increasingcell differentiation(p < 0.01). A similaritywas observedbetweenthe cytoplasmof hepatomacells and foetal hepatocytes.However, the surface of mitochondrialcristae per unit volume of the mitochondriaand the mitochondrialunit volume in malignant cells differ from those in foetal Cells.

Selectiveintestinaldecontamination (SID)with norfloxacin(NFX) is useful to preventinfections in cirmotic patients(CP) at high risk. The aim of the presentstudywas to determinethe durationof SID achievedwith oral NlX in CP and, therefore, whethertreatmentwith NFX shouldbe intermittent or must be continua's. PATImS AWL .NETHODS. FourteenCP receivedoral NFX (10 patients400 q/day and 4. 4CO mg bid) during7 days.Bacterialcountswere performedin fecal samples collectedbefore and after treatment,and then everyweek until total recoveryof fecal flora to the initialvalue.

of 180 paediatric liver transplant recipients, 19 (10.5%) had transplant for a metabolic disorder. Four had a1-antitrypsin deficiency (mean age 9.1 Y), 5 Wilson's disease (mean age 11.2 y), 3 tyrosinemia (Em, ly & 4y), 1 type IV glycogenosis (1 y). Five four had no liver insufficiency: Crigler-Najjar syndromes (2.2, 3., 3.5 h 7.5 Y), 1 type I glycogf3-tosls (7 (lOY* primary hyperoxalurla y),l +$ver-kidney transpla;;:;;;:).
