    Notes: Abstract Serum bile acids and their conjugates were analysed in 20 breast-fed infants with prolonged jaundice. The mean total bile acid levels in serum were increased in the breast-fed infants with jaundice, as compared with those in either breastor bottle-fed infants without jaundice. However, there were no significant differences between the groups. All the breast-fed infants examined, regardless of association with jaundice, had a bile acid pattern dominated by taurine conjugates (the ratio of glycine- to taurine-conjugated bile acid, G/T ratio, less than 1.00). In contrast, the bottle-fed infants without jaundice had a pattern dominated by glycine conjugates (G/T ratio, more than 1.00). Among the breast-fed infants with jaundice, the mean G/T ratio in those who had serum bilirubin levels over 10 mg/100 ml was significantly lower than that in those who had serum bilirubin levels of less than 10 mg/100 ml. The altered bile acid metabolism might be associated with the pathology of breast milk jaundice.

    Notes: Abstract As simple and nonsurgical means of differentiating biliary atresia (BA) from intrahepatic cholestasis of unknown origin (IC), liver function tests including serum lipoprotein-X (LP-X) and γ-glutamyltranspeptidase (GGTP) were done and evaluated for their usefulness in the diagnosis of 27 cholestatic Japanese young infants. Except for LP-X and GGTP levels (P〈0.01, P〈0.001), there were no significant differences between the BA (n=11) and IC (n=13) groups. When values of mean plus 4 standard deviations were used to differentiate BA from IC (89 mg/100 ml for LP-X and 194 IU/l for GGTP), all BA patients gave positive results for either the crtical LP-X of GGTP values. On the other hand, all IC patients gave negative results for both levels, although patients with a paucity of intrahepatic biliary ducts (n=3) were also positive for either the critical LP-X or GGTP values. The combination test with serum LP-X and GGTP is recommended for helping to differntiate BA from IC in cholestatic young infants.

    Notes: Summary Four groups (groups 1-4) of female Donryu rats were given continuously 400, 200, 100, or 0 ppm solution of 1,3-dibutyl-1-nitrosourea (B-BNU) as their drinking water, and were studied for the development of tumors. The incidence of mammary tumors was 15/19 (79%), 20/24 (83%), 21/26 (81%), and 8/25 (32%) in groups 1, 2, 3, and 4, respectively. In addition, hematopoietic neoplasms, uterine tumors, and vaginal tumors developed in 13, 11, and six rats, respectively in 69 treated rats. Other tumors were infrequent.
