The total free fatty acids, blood glucose, and individual free fatty acids were studied in 8 patients with viral hepatitis and 13 with cirrhosis. The results were compared with those obtained in 9 normal control subjects. Free fatty acids were significantly elevated in liver patients as compared with normal controls. A fall in free fatty acids following ingestion of amino acids and dextrose was noted in normal subjects as well as liver patients. Glucose tolerance test, when done on patients with liver disease, was abnormal in most cases. Highly significant differences were found in the composition of individual free fatty acids in liver patients as compared with normal subjects. Arachidonic and linoleic acids were decreased, while monounsaturated and saturated fatty acids were increased in patients with viral hepatitis and cirrhosis. No significant changes were noted in the percent composition of individual free fatty acids following ingestion of amino acids and dextrose.

In an infant with galactosemia high levels of galactose-1-phosphate in red blood cells and of blood galactose were observed under a "galactose-free'' diet. The child did not thrive and developed a liver cirrhosis. At the age of 5 months he died unexpectedly. Post mortem examination revealed in the pancreas and the small intestine changes suggestive of a cystic fibrosis. Since the exogenous administration of galactose by diet could be excluded the endogenous production of significant amounts of galactose-1-phosphate has to be considered.

Ethanol-1-14C method for the measurement of intrahepatic shunted blood flow was compared with the method of continuous infusion of D-galactose-1-14C. In controls, in chronic hepatitis, and in hepatic cirrhosis, per cent intrahepatic shunt measured by the ethanol-1-14C- method was about a half or one-third of that measured by the D-galactose-1-14C method. Study of radioactivity-dye concentration ratio of the blood sampled from the inferior vena cava showed that per cent intrahepatic shunt was underestimated by the ethanol-1-14C method because of permeability of ethanol-1-14C through the capillaries. In patients with hepatic carcinoma, in whom the carcinomatous tissue was supplied mainly by the hepatic artery, there was no significant difference in per cent intrahepatic shunt between both methods.

The plasma elimination curves of diazepam following intravenous administration of 10 mg were studied in nine patients with cirrhosis of the liver and four patients without liver disease. The data were analyzed according to a two compartment model. The mean biological half-life (T/2) of diazepam was increased five-fold in patients with cirrhosis compared to the controls (164 hours vs. 32.1 hours). The plasma clearance of diazepam could be correlated neither with a quantitative measure of liver function, as estimated by galactose elimination capacity, nor to semiquantitative measures of liver function, such as serum albumin and prothrombin. It is suggested that the plasma clearance of diazepam is an inaccurate index of its rate of hepatic metabolism due to the complex kinetics of the drug.

The method of measuring the rate of aminopyrine demethylation by breath analysis was assessed in 23 normal subjects and 20 patients with cirrhosis. Carbon 14 aminopyrine specifically labeled at the two N-methyl groups was administered by mouth in a dose of 9 mg/kg, including a total radioactivity of 2 muCi. The decay of the specific activity of 14CO2 in breath (kb) was found to correlate (r = 0.91) with the disappearance of aminopyrine from plasma (KP). In normal volunteers, kb was 22.4%/hr; in patients with alcoholic and nonalcoholic cirrhosis it was depressed to 8.4%/hr (p less than 0.001). The degree of functional impairment found with the breath test was similar to the sulfobromophthalein (BSP) disappearance curve and the galactose elimination capacity. Although many questions relating to the aminopyrine breath test remain open, our data confirm and extend previous studies of 14CO2 breath analysis after 14C-aminopyrine administration. It is concluded that it represents a simple and noninvasive procedure which quantitatively reflects the microsomal function of the cirrhotic liver.

In 12 patients with cirrhosis of the liver, determination of the liver volume by ultrasonic scanning and of the galactose elimination capacity (GE) were made before and after portal decompression surgery. The liver volume decreased significantly, with a median decrease of 402 ml (psmaller than 0.01). Also the GE decreased, but relatively less than the liver volume, so that the calculated GE per unit liver volume increased, with a median increase of 5 mg per minute times 100 ml liver volume (psmaller than 0.005). The decrease in liver volume following portal decompression is assumed to be due in part to reduction of liver blood volume, in part to loss of tissue water and fat, and probably to some loss of parenchyma, accounting for a reduction of the GE.

In 31 patients with cirrhosis of the liver undergoing porta-caval shunt surgery, the prognostic value of some liver function tests was studied. The surgical mortality was not correlated with the test results. Serum concentrations of bilirubin, albumin, and prothrombin were not correlated with postoperative encephalopathy, but the mutually correlated preoperative galactose elimination capacity and age of patients were correlated with encephalopathy development. Incapacitating encephalopathy mainly occurred in patients above 60 years of age, and when the galactose elimination capacity was at or less than an arbitrary limit of 225 mg/min. The liver function decreased significantly following operation.

An infant with galactosemia is reported in whom extensive liver damage developed by 1 month of age. Liver biopsy obtained prior to treatment indicated extensive periportal and intralobular fibrosis, ductular cysplasia. "pseudoglandular" transformation, and distortion of periportal vasculature. Three months after institution of a galactose-free diet, clinical and biological evidence of liver disease disappeared, and follow-up biopsy at 5 months of age showed normal hepatic histology. These findings demonstrate that functional and histological abnormalities consistent with cirrhosis can be completely reversed by dietary management in galactosemia.

Liver cirrhosis was not found by needle biopsy performed on 28 consecutive male alcoholics of "skid-row" type, but 14 had fatty degeneration and 14 normal histology of the liver. Hypoalbuminemia was the most consistent finding. The combined galactose tolerance test could not predict fatty degeneration. There was no correlation between the laboratory tests used to assess liver function and the degree of fatty degeneration.

After ingestion of galactose (10 g per m2) labeled with 14C or 13C, breath was collected from subjects at intervals for 4 hr followed by measurement of 14CO2 by liquid scintillation counting or of 13CO2 by mass spectrometry. Nine subjects without liver disease and 21 "cirrhotic" patients were tested with 14C; 8 control subjects and 4 patients with diagnosis of cirrhosis were tested with 13C. The mean rates of expiration of labeled CO2 by the patients with "cirrhosis" were one-third to one-half of mean normal rates during the first 90 min. The time of peak concentration of tracer CO2 for cirrhotic patients (150 to 180 min) was later than for normal subjects (90 to 120 min). There was distinctly greater separation between control and liver disease groups by test of 14CO2 radioactivity at 1 hr than by serum alkaline phosphatase, total bilirubin, and transaminase, but only slightly better separation than by serum albumin concentration (which was highly correlated with 14CO2 output). The [14C]galactose test is simpler than the standard intravenous galactose tolerance test, and , like the latter, appears superior to some other tests for recognition of cirrhosis. The use of 13C provides an example of a new direction for clinical application of this stable, nonradioactive nuclide.
