In a survey of 430 Lori-Bakhtiari sheep at a slaughterhouse in Iran, gallstones were found in the gallbladder of 7 sheep (1.6%). Biliary calculi were more frequent in adult and female sheep (P < 0.05). Chemical analysis of the gallstones revealed 6 sheep with pigment (bilirubin) stones and 1 sheep with cholesterol stones. Chemical composition of bile in these sheep was evaluated. Bacteriologic ...

This paper attempts to deduce the prevalence of gallstones by the use of previously published necropsy data. These data are interpreted as suggesting that the incidence of gallstone development is similar in North America, Australia, Great Britain, and Norway and is largely independent of age between the third and eighth decades. Data are also presented which may imply that the total mortality ...

Biliary tract carcinomas which include cancer of the gall bladder and intrahepatic and extrahepatic biliary tree are relatively infrequent but highly lethal diseases that are notoriously difficult to diagnose and treat. Objective: To study the relation of gallstones and malignant histopathological changes in gallbladder with correlation of size and no. of gallstones in causation or predispositi...

Cholelithiasis, or gallstones, is one of the most common and costly of all the gastrointestinal diseases. The incidence of gallstones increases with age. At-risk populations include persons with diabetes mellitus, persons who are obese, women, rapid weight cyclers, and patients on hormone therapy or taking oral contraceptives. Most patients are asymptomatic; gallstones are discovered incidental...

Although protein is the third most abundant solid in bile and is important in cholesterol crystal formation, methods for quantitating the concentration of total protein in bile have not been systematically evaluated. To establish a reliable protein assay for bile, we evaluated three protein assays (Lowry's method and the fluorescamine and Coomassie blue methods), and employed amino acid analysi...

STUDY OBJECTIVE The aim was to evaluate the hypothesis that sunlight exposure leads to the development of gallstones in people with a sun sensitive skin. DESIGN AND SETTING This was a case-control study among 206 white patients referred for an ultrasound examination of the gallbladder. Sunlight exposure and skin sensitivity were retrospectively assessed by a structured questionnaire. The ques...

BACKGROUND Gallstones are a highly prevalent condition; however, the nutritional and lifestyle risk factors of this disease are not well understood. OBJECTIVE We evaluated the association between diet, physical activity, and incident cases of gallstones diagnosed by ultrasound in a population-based, case-control study. DESIGN One hundred patients with newly diagnosed gallstones and 290 rand...

CONTEXT little is known about the epidemiology of cholelithiasis in children. Cholelithiasis and choledocholithiasis were considered to be uncommon in infants and children but have been increasingly diagnosed in recent years due to wide- spread use of ultrasonography. However, there is not much of information from India and no consensus among Indian pediatricians and pediatric surgeons regardin...

We investigated the prevalence of gallstones after gastrectomy by abdominal ultrasonography in 289 gastrectomized patients selected from 51,621 Automated Multiphasic Health Testing and Services (AMHTS) examinees after barium meal studies. The results were compared with those of another group of 3,193 AMHTS patients who routinely underwent ultrasonography (control). Among the gastrectomized pati...

In Mexico, Raphanus sativus L. var. niger (black radish) has uses for the treatment of gallstones and for decreasing lipids serum levels. We evaluate the effect of juice squeezed from black radish root in cholesterol gallstones and serum lipids of mice. The toxicity of juice was analyzed according to the OECD guidelines. We used female C57BL/6 mice fed with a lithogenic diet. We performed histo...
