[Blood coagulation factors in hepatic disorders].

The major factors related to the coagulo-fibrinolytic reactions are synthesized in the hepatic cells. As a reticuloendothelial organ, the liver also removes the activated factors and metabolic products in the coagulo-fibrinolytic process from the plasma. Therefore, many investigators have been trying to use measurements of the coagulo-fibrinolytic factors for the evaluation of the type and degree of a hepatic disorder and for the determination of therapeutic effects or prognosis. On the other hand, the recent advances in the blood coagulation study show that the hemostatic mechanism is a kind of maintenance mechanism of homeostasis for blood-flow. The functions of many factors in and from the platelets and vascular endothelial cells as well as those produced by the liver have been identified. Recently, some hemostatic molecular markers and complexes of activated factors with their inhibitors can also be measured. In this article, the recent concept of hemostatic mechanism and the relation between various hemostatic factors and hepatic disorders are presented.

[Clinical significance of the measurement of serum pepsinogen group I and II by enzyme-linked immunosorbent assay].

We have developed enzyme-linked immunosorbent assay (ELISA) for pepsinogen group I and II (PG I.II) in human serum, and clinical significance of serum pepsinogen measurement was evaluated. Serum PG I.II levels in patients with gastric and duodenal ulcer were higher than those in normal healthy subjects. On the other hand, serum PG I levels in patients with pernicious anemia were significantly low levels. In both gastric ulcer and duodenal ulcer, serum PG I.II levels at active stage were higher than healing stage. These results suggested that the measurement of PG I.II levels was useful for screening or monitoring test for the injury of gastric and duodenal mucosa.

[Long-term follow-up study of alcoholic liver disease].

Two hundred seventy-one patients with various forms of alcoholic liver disease were followed up for an average of 87.9 months. The survival was the lowest for alcoholic cirrhosis (average 10-year survival: 23.8%). Prognosis was grave especially in cirrhotic patients who continued drinking, owing mainly to the increased death due to gastrointestinal bleeding. The development of hepatocellular carcinoma (HCC) was observed during the first six years only in cirrhosis. The average 5-year probability rate of developing HCC for cirrhosis was 16.3%. The rate was significantly higher for the cirrhotic patients who abstained than for those who continued drinking. Serial biopsies were performed on 66 non-cirrhotic patients who continued drinking. The mean duration of histological follow-up 46.0 months. Cirrhosis developed eventually in 30.3% of the cases. In conclusion, the present study indicates that continued drinking causes progressive liver damage and a poor prognosis. Our data also suggest that abstinence is associated with an increased risk of HCC in cirrhosis. Thus, it is important to recover from alcoholism before cirrhosis develops.

Effects of routes of administration on the cyanide concentration distribution in the various organs of cyanide-intoxicated rats.

Cyanide concentrations in various organs (the blood, liver, lung, spleen and brain) of the rats intoxicated by ingestion or inhalation were determined with a slightly modified microdiffusion method. In the inhalation experiment, a rat in an exposure chamber inhaled HCN produced by addition of NaCN solution to H2SO4. For each route two different doses were used. The time to death was shorter when doses were larger. Cyanide concentrations were higher in per os group than in inhalation group in all the organs tested. The concentration in the liver was most sensitive to the route of administration; it was the highest among the organs tested after per os administration, but low after inhalation. In the lung it was significantly higher than that of the blood when cyanide was inhaled. It was concluded that, when it is necessary to determine whether cyanide was ingested to inhaled, at least the lung and liver must be analyzed for cyanide contents in addition to the blood and stomach content.
