38. Effect of Oral Chenodeoxycholic Acid on Bile Acid Kinetics and Biliary Lipid Composition in Women with Cholelithiasis
Bile acid kinetics and biliary lipid composition were characterized in six women with gallstones before and after 6 mo of oral therapy with chenodeoxycholic acid, an agent that induces dissolution of cholesterol gallstones in man. Over a dosage range of 1-4 g/day, absorption varied from 0.8 to 2.3 g/day. The chenodeoxycholic acid pool expanded two-to sixfold

39. Hereditary spherocytosis. Recent experience and current concepts of pathophysiology.
Hereditary spherocytosis is a clinically heterogeneous, genetically determined red blood cell membrane disorder resulting in hemolytic anemia. A deficiency of spectrin, the largest and most abundant structural protein of the erythrocyte membrane skeleton, results in the formation of spherocytes which lack the strength, durability, and flexibility to withstan

40. Ursodeoxycholic acid dissolution of gallstones in cystic fibrosis
The dissolution of cholesterol gall stones is documented in two adults with cystic fibrosis.

41. From the surgery to the surgeon: does deprivation influence consultation and operation rates?
BACKGROUND: Concern about equity of access to health care has increased since the health care reforms implemented in the 1990s. Access to specialist health care is controlled by general practitioners; assessing and ensuring equity should therefore begin in general practice. AIM: This study set out to determine whether there are socioeconomic differences in t

42. Biliary tract cancers in Cote-d'Or (France): incidence and natural history.
The registry of digestive tract tumours established for the department of Cote-d'Or (France) was used to study the epidemiological characteristics and the natural history of biliary tract cancers. Age standardised incidence rates for gallbladder cancers were 2.7/100,000 for women and 0.9/100,000 for men. The corresponding rates for extrahepatic bile duct can

43. Cirrhosis and alcoholism as pathogenetic factors in pigment gallstone formation.
The association of cirrhosis with pigment gallstones has been noted in numerous autopsy studies. However a direct relationship between alcoholism and pigment cholelithiasis has not been previously demonstrated. We have classified 123 cholecystectomy patients according to stone type and correlated the resulting categories with hepatic morphology, drinking his

44. Liver disease in women. Alcohol, autoimmunity, and gallstones.
Some liver diseases, such as autoimmune liver disease, affect women far more often than men. Others, such as alcohol-related disease, progress more rapidly in women than in men. An increased index of suspicion will lead to improved diagnosis and earlier treatment of women with liver disease.

45. Sulfation of Lithocholate as a Possible Modifier of Chenodeoxycholic Acid-induced Elevations of Serum Transaminase in Patients with Gallstones
Chenodeoxycholic acid (CDC), through its metabolite, lithocholic acid (LC), is hepatotoxic in certain species. The cause of elevations of serum transaminase in 25% of humans ingesting CDC, however, is unknown, but also may be due to LC. Because efficient hepatic sulfation of LC may protect against hepatic injury, the aim of this study was to determine if sul

46. Effects of dietary cholesterol on cholesterol and bile acid homeostasis in patients with cholesterol gallstones.
We examined changes in cholesterol and bile acid metabolism produced by dietary cholesterol in gallstone subjects and matched controls. Healthy women were recruited and, after confirming the presence or absence of radiolucent gallstones, they were studied on regular diets and again on the same diet supplemented with five eggs daily for 15-18 d. Studies inclu

47. Increased susceptibility to diet-induced gallstones in liver fatty acid binding protein knockout mices⃞
Quantitative trait mapping identified a locus colocalizing with L-Fabp, encoding liver fatty acid binding protein, as a positional candidate for murine gallstone susceptibility. When fed a lithogenic diet (LD) for 2 weeks, L-Fabp−/− mice became hypercholesterolemic with increased hepatic VLDL cholesterol secretion. Seventy-five percent of L-Fabp−/− m

48. Progesterone alters biliary flow dynamics.
OBJECTIVE: To test the hypothesis that progesterone alters sphincter of Oddi and gallbladder function and, therefore, bile flow dynamics. SUMMARY BACKGROUND DATA: Although the effects of progesterone on the biliary tract have been implicated in the increased incidence of gallstones among women, the specific effects of prolonged elevation of progesterone leve
