The serum cholylglycine (CG), alanine aminotransferase (ALT) and total bilirubin levels were studied in 210 patients with hepatobiliary disease and in 70 healthy subjects. Serum CG concentrations in all the hepatobiliary diseases were found to be significantly higher than those of their controls. Patients with abnormal increases in ALT and bilirubin levels also showed raised CG concentrations; however, some patients with normal ALT and bilirubin levels, still had markedly elevated CG values. Patients with hepatic cirrhosis had high serum CG levels, followed, in descending order, by chronic active hepatitis and chronic persistent hepatitis. In the cholecystitis and cholelithiasis cases, their CG levels were significantly higher than those of the controls but lower than the values in hepatic disease patients; however, more cholecystitis cases had abnormally high serum bilirubin levels than CG. The results also show that serum CG concentrations vary in the different hepatobiliary diseases, and that serial CG measurements are more sensitive than measuring ALT and bilirubin levels in the diagnosis of hepatic diseases. Serum CG can be used as an index for evaluating the activity of chronic hepatitis; it can also be employed as a diagnostic tool in cholecystitis and cholelithiasis.

Blood serum free vitamin B12, bilirubin, alanine aminotransferase levels were measured and thymol test made in 168 patients with viral hepatitis A, 13 with chronic hepatitis, 8 with mechanical jaundice of neoplastic origin, 7 with calculous cholecystitis, and 8 with functional hyperbilirubinemia by the microbiologic methods. Elevated blood serum levels of free vitamin B12, conforming to the disease severity and stage, were revealed in the patients with viral hepatitis A, chronic active hepatitis, and mechanical jaundice of a neoplastic origin with liver involvement. Correlations between cobalaminemia and other functional liver tests were observed. Therefore blood serum vitamin B12 measurements may be used for the assessment of the disease activity and severity of liver parenchyma injury.

Brachytherapy by embolization with radiotherapeutic microspheres following intraarterial infusion of a radiosensitizer represents an attempt to combine several selective modalities into a more potent, focused attack on regionally confined tumors. In pursuit of this goal, we examined the ability of foxhounds with surgically implanted hepatic arterial (HA) delivery systems to tolerate a clinically relevant dosage of HA yttrium-90 (Y-90) by microsphere administration either alone or preceded by a 28-day constant HA infusion of either 5-bromo-2'-deoxyuridine (BUDR) or a control solution. Five dogs received BUDR (10 mg/kg/day) and five a control buffer infusion for 28 days immediately prior to the administration of Y-90-coated 15 micron resin microspheres (equivalent of 5000 rads to the entire liver) to each dog on day 31. In all animals, blood counts, bilirubin, amylase, appetite, weight, and behavior remained unchanged. Dogs receiving the microspheres after buffer infusion alone exhibited no hepatic enzyme alanine aminotransferase or alkaline phosphatase elevation. Alanine aminotransferase and alkaline phosphatase levels both rose during the third week of BUDR infusion, and while subsequent microsphere administration further increased enzyme levels, these levels had largely normalized by necropsy on day 82. At necropsy, the type and degree of hepatic toxicity among the animals receiving radioactive microspheres was comparable to that previously described in patients receiving external beam hepatic irradiation at conventional doses (2000-3000 rads). Also noted was a radiation-induced cholecystitis (due in large part to the gallbladder's total reliance on the hepatic artery for blood supply). One resin microsphere dog exhibited a small quantity of microspheres in the lungs causing focal radiation-induced granulomas suggesting the need to assess shunting of microspheres through the liver in clinical studies. Thus, HA Y-90 microspheres with BUDR can produce acceptable, nonlethal, and tolerable toxicities in this dog model suggesting that clinical studies of this combination are not likely to be contraindicated by synergistic toxicity. Although HA BUDR did not contribute significantly to the toxicity of the Y-90 microspheres, HA BUDR by itself administered uninterrupted for 4 weeks may, like HA FUDR (clinically), cause chemical hepatitis/cholangitis. The unexpected fragmentation of the resin spheres (albeit without myelosuppression) has led us to begin studies with a recently developed nondisruptible glass microsphere (ThereSphere) in which the Y-90 is part of the glass matrix and cannot leach.(ABSTRACT TRUNCATED AT 400 WORDS)

A 4-year-old cat was examined because of anorexia and lethargy. The cat became icteric within 3 days of admission. Values for aspartate transaminase, alanine transaminase, total bilirubin, alkaline phosphatase, and cholesterol were higher than normal. Radiography revealed hepatomegaly, with loss of detail in the cranioventral portion of the abdomen. Further diagnostic procedures were not permitted, and the cat was euthanatized. At necropsy, cholecystitis, cholangitis, and numerous choleliths were found. Cholelithiasis is a rare cause of obstructive jaundice in the cat.

Two hundred and forty-three patients aged under 75 years with acute calculous cholecystitis treated by early surgery were studied with a view to investigating the frequency of choledocholithiasis and the predictive value of routine liver function tests (bilirubin, alkaline phosphatase, alanine aminotransferase). 7% had stones in the common duct, but 33% had hyperbilirubinaemia. In less than 10% of the latter could be hyperbilirubinaemia be attributed to common bile duct stones. It was concluded that the frequency of common bile duct stones in acute cholecystitis was low, and that patients often had signs of impaired liver function which was of no help in diagnosing the presence of stones in the common duct.

Sisomicin sulfate (SISO) was used for the treatment of infections complicated by malignant diseases in 10 cases; 4 cases with suspicious sepsis, 2 with pneumonia, 2 with urinary tract infection, 1 with renal abscess and 1 with cholecystitis. SISO was administered by intravenous drip infusion at daily dose from 100 to 150 mg for 6 to 12 days, concomitantly with other antibiotics. Clinical results were as follows; Good in 2, fair in 5, poor in 3 cases. As to the side effects of SISO, cylindruria with aggravation of microscopic hematuria and elevations of GOT, GPT and A1-P were observed each one of them, respectively. The relationship to the SISO, however, was not clear. In view of the above results, the drip infusion of SISO may be useful for the treatment of serious infection complicated by malignant diseases.

Destructive, inflammatory and sclerotic alterations of the hepatic tissue, increased content of lipid inclusions, lysosomes and microbodies in hepatocytes, vesiculation of the endoplasmic reticulum and depletion of ribosomal granules in it were revealed by morphological examinations of liver samples from the gall bladder bed from patients will rarely, frequently and continuously recurring chronic cholecystitis. A relationship between resorption of lipid structures, content of lysosomes and microbodies, and glycogen accumulation in hepatic cells was found. The destructive morphological changes correlated with reduced capacity of the liver to absorb radioactive label, an increase of alanine transaminase level in the blood, and decreased oxidative processes in the mitochondrial fraction of the liver. The results of the study attest to the involvement of the liver in the pathological process in accord with the rate of cholecystitis recurrency.

Functional abnormalities of the liver uncovered during preoperative routine evaluation were analyzed in 109 donor candidates for 100 cases of living-related liver transplantation (LRLT) performed during the period from June, 1990 to May, 1994 at the Second Department of Surgery, Kyoto University Hospital. High serum transaminase (GOT, GPT) levels were noted in 10 (9.2%) cases among 109 candidates, high alkaline phosphatase in 4 (3.7%), hyperbilirubinemia in 3 (2.8%), anemia in 3 and high choline esterase in 3 cases. Positive hepatitis C antibody (HCV) was also noted in 1 case. Fatty liver was detected in 10 (9.2%) cases, cholecystitis in 2 cases, 1 case each of cyst and calcification in the liver by diagnostic imaging (ultra sonograph and/or computed tomography). These abnormalities of the liver necessitated replacing the initial candidate with the other parent in 9 cases, including 1 case without any functional abnormality whose graft liver was too large to fit the recipient abdominal cavity. There were 14 cases of ABO blood type incompatible combination. Switching the initial candidate due to these abnormalities mentioned above resulted in incompatible combinations in 4 of these 14 cases. Although the advantages of the LRLT are the superior viability of the donor graft and the genetic histocompatibility between recipient and donor, to optimize the advantage of LRLT, all donor candidates should be strongly advised to make every effort preoperatively to improve their physical condition in preparation for the LRLT protocol, since many of these abnormalities are typically reversible.

Plachitin formed of both poly-N-acetyl-D-glucosamine (chitin) and cis-diamminedichloroplatinum (CDDP), was used as an arterial chemoembolization therapy against unresectable liver cancer. One gram of Plachitin contained 300 mg of CDDP. The Plachitin particle was 50-100 microns in diameter. Plachitin particles (50-100 mg) were injected via hepatic artery once or twice every week, and the total amount of 300 mg was considered one course of this therapy. The size and number of tumors were measured by computer tomography (CT). Pharmacokinetics of this drug was also assessed by serum and urine platinum (Pt) concentration. Three patients underwent the chemoembolization therapy using plachitin particles. Case 1 had multiple hepatocellular carcinomas. The tumor regression rate was 39% after two courses of this therapy. Serum alpha-fetoprotein (AFP) level decreased from 1,182 ng/ml to 300 ng/ml. Case 2 suffered from bile duct cystadenocarcinoma. After three courses of the therapy, the tumor regression rate was 84.4%. Serum carbohydrate antigen 19-9 (CA19-9) decreased from 731 U/ml to 75 U/ml. Case 3 had synchronous multiple liver metastases from sigmoid colon cancer. The tumor regression rate was 77% after one course of the therapy. Carcinoembryonic antigen (CEA) and CA19-9 decreased from 406 ng/ml to 65 ng/ml and from 4,800 U/ml to 790 ng/ml, respectively. The response rate of the 3 cases was 66.7%. The peak levels of the serum Pt concentration of three patients were 0-0.4 microgram/g throughout the therapy, but peak urine Pt concentrations were observed during one course of the therapy of three patients ranging from 0.5 microgram/g to 3.2 micrograms/g, and decreased gradually for three weeks after the first course. Adverse effects of Plachitin particles for arterial chemoembolization were epigastralgia, nausea, fever, and elevation of serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels. These adverse effects were observed in all patients, but were transient. Catheter obstruction occurred in one patient (case 2). Cholecystitis, pancreatic pseudocyst, and duodenal ulcer were noticed in case 3. No renal hypofunction was observed. Plachitin might be a useful agent for arterial chemoembolization therapy for primary and secondary liver cancer.

Progressive liver failure in parenteral nutrition (PN)-dependent children with short bowel syndrome carries significant morbidity and mortality. The authors retrospectively reviewed 47 consecutive patients with short bowel syndrome diagnosed from October 1985 through October 1995. All patients were treated according to a protocol designed to promote intestinal motility and discourage bacterial translocation. Elements of the protocol included the use of taurine, vigilant prevention and aggressive treatment of sepsis, meticulous catheter care, early PN cycling, appropriate enteral feeding, and measures designed to inhibit gastrointestinal bacterial translocation, especially gram-negative rods. Complete blood counts and serum liver function studies were compiled from both clinic visits and hospital admissions for each patient every 3 to 6 months while they were on PN. Three patients were lost to follow-up after they had moved out of state. The length of time on PN ranged from 3 months to 9.4 years with an average of 2.2 years. Elevated aspartate aminotransferase (AST), alanine aminotransferase (ALT), and glutamyltransferase (GGT) were present in 82%, 66%, and 84% of patients, respectively. Alkaline phosphatase was elevated in 58% of patients. Eight patients (18%) are still on PN, and 31 (70%) have been weaned off PN. Five patients have died (11%). Three patients (7%) developed cholecystitis requiring cholecystectomy. No patients developed progressive liver failure. These results suggest that PN-related liver failure may be prevented in most patients with short bowel syndrome. Specific measures to prevent PN-related cholestatic jaundice need further investigation.
