Determination of 15N-ammonia by chemical ionization mass spectrometry.
The tracing of ammonium nitrogen is important in hepatic diseases, especially in liver cirrhosis with hyperammonemia. In this paper, a new convenient method is described for determining stable isotope 15N-labeled ammonia using the Conway apparatus and chemical ionization mass spectrometry. The minimum quantity of ammonia necessary for reliable measure of 15N content was 0.1 muMol. The average error was 5.3%. In clinical application, 4 ml of blood after oral administration of 1 g of 15NH4Cl was sufficient for measurement.

Clinical course and prognosis of one hundred and two patients with hepatic coma 1958 through 1975.
The clinical course and prognosis of hepatic coma were examined in 102 patients treated in the period from 1958 to 1975. The diagnoses included 9 fulminant hepatitis, 7 subacute hepatitis, 53 liver cirrhosis without liver carcinoma (40 cases of the acute type, 10 cases of the chronic type and 3 cases of another type, according to Sherlock's classification of hepatic coma) and 33 liver cirrhosis with primary liver carcinoma. Four of 9 fulminant hepatitis patients gained consciousness within 1 week and recovered completely. Seven subacute hepatitis patients died within 2 weeks after onset of hepatic coma. In the period from 1958 to 1969, 20% of liver cirrhosis patients with the acute type of coma recovered from coma, and in the period from 1970 to 1975, 45% of patients recovered. Seven of 10 patients with the chronic type of coma died between 4 months and 9 years after the onset of coma. Three other patients are presently still alive. The median survival time was 2.5 years. Nine primary liver carcinoma patients with coma were hospitalized from 1958 to 1969 and 24 from 1970 to 1975. Hepatorenal syndrome was present in 31 of 71 examined patients. Twenty-three patients with hepatorenal syndrome were in the period from 1970 to 1975.

Scanning electron microscopy of the bile ductule.
Scanning electron microscopy of a liver biopsy specimen from a patient 6 months after the onset of acute hepatitis revealed a normal appearing bile ductule. The bile ductule was 13 micron in outer diameter and 1.5-2.7 micron in inner diameter. The ductular lumen was surrounded by two ductular cells and ampullary dilated at the canalicular side. In the lumen, intracytoplasmic diverticles were observed with an orifice diameter of 0.9 micron. About 15 microvilli 0.4-0.6 micron in length and 0.1 micron in thickness were observed on 1 micron2 of luminal surface. The number of microvilli was calculated to be approximately 1,500 per ductular cell. A single cilium 0.15 micron in diameter at the base and 0.10 micron at the trunk, and 7-15 micron in length was found on each ductular cell. The cilium arose from a recess at the canalicular side of the ductular cell, and the free-end was on the bile-duct side. The cilia seemed to play an important role in bile flow to the duct. Sometimes between the ductular cells at the edge of the basal portion a cell was intercalated with thin processes. Such thin processes were not observed on ductular cells.

Peritoneoscopic diagnosis of liver surface--using a new code number system--.
A new peritoneoscopic classification of liver surface using a three digit code was developed. The first digit represents the lobular change from normal structure to nodules. The second digit represents the size of the nodule and the internodular distance. The third digit represents the pathological findings, such as inflammation, degeneration, necrosis or regeneration. Furthermore, peritoneoscopic findings of necrosis of lobular size around the portal vein and patchy markings of the liver were presented. These findings were the most prominent in the course of hepatitis progression to cirrhosis.
