The results from the complex study on 26 patients with primary biliary cirrhosis (PBC), 20 females and 6 males, an average age of 46 years, are reported. The most frequent symptoms of PBC are itching, jaundice, hepatosplenomegaly; from the laboratory tests--most characteristic is the increase of serum 5'-nucleotidase, AP, LAP, gamma GTP, GOT, cholesterol, cholic acid and antimitochondrial antibodies and IgM (AP, 5'-nucleotidase and antimitochondrial antibodies, being most significant in making the early diagnosis). The laboratory results in PBC are compared with those of the chronic active hepatitis, cirrhosis of the liver, liver cancer, extrahepatic cholestasis, with outlining the characteristic differences, depending on the diagnosis. The diagnostic advantages of the various methods are discussed (mainly laparoscopy and liver biopsy) and the histologic and electron microscopic changes of percutaneous transhepatic cholangiography, via echography--81 per cent, laparoscopy--73 per cent, scintigraphy--61.53 per cent and liver biopsy--50 per cent. The results from the treatment with cholestrimine, corticosteroids and azathioprine and surgical treatment, observing a temporary improvement and progressing of PBC, are reported. With the follow-up care of 20 patients, it was established, that 9 had died 5 years, on the average, after making the diagnosis, 11 survived after the 5 years and they are still followed up. The longest survival was reported in two females--11 and 15 years after the onset of PBC.

The greater part of the intracellular aminopeptidases in Pseudomonas aeruginosa and Acinetobacter calcoaceticus is soluble. The localization of aminopeptidases in the cells was examined using the osmotic shock method with some modifications. When the cells of A. calcoaceticus and P. aeruginosa of the logarithmic phase were subjected to an osmotic shock, all aminopeptidases investigated were mainly localized in the sucrose supernatants and in the periplasm. Acid phosphatase as marker enzyme for periplasm showed a similar distribution between the fractions as the aminopeptidases. The periplasmic aminopeptidases of both microorganisms were separated by FPLC on Superose 12 and their molecular masses were determined. The results obtained show that at least four different aminopeptidases occur in the periplasm, a leucyl aminopeptidase (LAP, cleaving Leu-NH-NH2, 400 kDa), a glutamyl aminopeptidase (GAP, 200 kDa), an alanyl aminopeptidase (AAP, 80 kDa) and a prolyl aminopeptidase (PAP, 65 kDa). The results are in agreement for both species. Our results show clearly that aminopeptidases of these typical members of Gram-negative bacteria are mainly periplasmic like degrading enzymes (alkaline and acid phosphatases, 5'-nucleotidase, cyclic phosphodiesterase), detoxifying enzymes and binding proteins for amino acids and sugars.
