It is generally accepted that the bile acids are responsible for pathologies as a result of deficiency or by toxic action. Quantitative deficiency is difficult to evaluate but the normal pool of bile acids is generally considered to be between 2 and4 grams. Daily loss and replacement by synthesis is thought to be between 500 and 700 mg. There is experimental evidence to demonstrate the toxic action of certain bile acids on metabolic structures and processes. There is no doubt that alterations in the metabolism of bile acids give rise to certain pathologic aspects in some diseases of the gastrointestinal tract or the hepatobiliary system. There are other conditions, on the other hand, in which the study of these acids may reveal significant physiopathologic implications. The first group includes terminal ileopathy, blind loop syndrome, gastric ulcer, gastritis, cholestasis, cirrhosis of the liver, and cholelithiasis. In the second group are such diverse conditions as acute pancreatitis, cancer of the colon, endocrine disturbances, some hyperlipidemias, and others. Much of the present day understanding of the physiopathology of the bile acids will probably have to be revised in the nex few years, in view of the rapid advances being made in this field.

A 58-year-old man manifested obstructive jaundice secondary to adenocarcinoma of the common hepatic duct. The markedly icteric patient underwent multiple diagnostic and therapeutic procedures, including percutaneous needle biopsy of the liver, curettage, catheterization and washing of the hepatic ducts, and percutaneous transhepatic cholangiography. Three months later the patient died of a bleeding gastric ulcer. Autopsy confirmed the presence of adenocarcinoma of the common hepatic duct. Microscopic examination of the lungs disclosed numerous bile emboli in the smaller arteries, arterioles, and in a few alveolar capillaries. Histochemical reaction of the emboli was positive for bilirubin. Organizing fibrin was seen around occasional bile emboli, but most were without microscopic reaction. Review of the literature disclosed nine cases of pulmonary bile embolism, six of which had a history of marked cholestasis and trauma to the liver, like the present patient. Bile reaches the systemic circulation through a biliary-venous fistula that, in our case, was probably iatrogenic.

This case report concerns a 35-year-old woman suffering from gravidic cholestasis, thrombocytosis and iterative vomiting episodes who underwent an elective cesarean section at week 35 because of recent herpetic vulvitis. Large bilateral ovarian tumors were observed which were interpreted as pregnancy luteomas. Nevertheless a biopsy of the right ovary was performed. Histologic examination revealed massive luteinization of the ovarian stroma. In addition, large tumor cells were found dispersed throughout the ovary as well as in vascular spaces as either isolated or clustered signet-ring cells. In search of the primary tumor, gastroscopy revealed a gastric ulcer in the antrum. The biopsies of the ulcer margins as well as those taken at distance demonstrated signet-ring cells in the lamina propria. Bilateral salpingo-oophorectomy and total gastrectomy were performed. In spite of postoperative chemotherapy, the patient died of disease 5 months after diagnosis.

An enzymatic, kinetic method for determining serum lipase activity was evaluated and compared to a standard manual method for use in dogs. The kinetic method was a commercial kit adapted for use on a tandem access clinical chemistry analyzer and utilized a series of coupled enzymatic reactions based on the hydrolysis of 1,2-diglyceride by lipase. The manual method was the Cherry-Crandall technique based on the titration of base against the acid formed by hydrolysis of an olive oil substrate by lipase. The correlation between the two methods was very good (r = 0.94). The reference range for 56 clinically healthy dogs assayed by the kinetic method was 90 to 527 U/L. Diseases associated with a greater than twofold elevation in serum lipase activity as determined by the kinetic method included pancreatitis, gastritis with liver disease, and oliguric renal failure with metabolic acidosis. In some cases, pancreatitis was seen with other clinical problems, such as gastroenteritis, diabetic ketoacidosis, duodenal mass, disseminated intravascular coagulation, and septic peritonitis. Diseases associated with serum lipase activity within the reference range or elevated less than twofold included gastritis, gastric ulcer, cholestasis, phenobarbital-induced hepatopathy, colitis, copper hepatopathy, abdominal hematoma, apocrine gland adenocarcinoma, and thrombocytopenia with pneumonia.
