62 specimens of cystic fluid drawn back by ultrasound guided needle-aspiration in 37 males and 25 females were evaluated biochemical analysis including magnesium, calcium, phosphorus, chloride, uric acid, total protein, sugar, urea, creatinine, sodium, potassium, total cholesterol, AST, ALT, ALP, ACP, PAP, alpha-amilasys. In our study Cl, Na and sugar showed similar concentrations in the two fluids. Uric acid, and urea were more concentrated in the cystic fluid while Mg, Ca and total protein were more pronounced in the blood. The results obtained seem to indicate that simple renal cyst could originate from glomerular proximal tubulus part of the nephron as consequence of an obstructive cause.

Primary liver carcinoma (PLC) may express a certain number of markers. Here we communicate results of an analysis of five such markers (alpha-1-antitrypsin--AAT--, carcino-embryonic antigen --CEA--, alpha-fetoprotein --AFP--, and superficial --HBsAg-- and core --HBcAg-- antigens of hepatitis B virus) by means of PAP techniques in 130 cases of PLC, comparing the neoplastic tissue and the non-tumorous liver. Three variants of PLC are distinguished: hepatocarcinoma (HC) (108 cases); cholangiocarcinoma (CC) (19 cases); and three cases of hepatocholangiocarcinoma (HCC). AAT was positive in 29 HC, 2 HCC, and negative in all 19 CC. CEA appeared positive in 16 HC, 16 CC and only one HCC. AFP was positive in two HC, and negative in all CC and HCC. HBsAg displayed positivity in 15 HC and one HCC, being negative in all 19 CC. HBcAg was positive in 4 HC, and negative in all CC and HCC. HBsAg was also positive in two neoplastic emboli associated with HC. On the non-tumorous liver tissue the immunohistochemical results showed positivity for AAT and CEA, but not for AFP. Therefore the present results confirm that in the geographical area from which these tumors proceed, PLC is closely correlated with HBsAg positivity and with cirrhosis.

PAP of harvested livers is routinely used to minimize parenchymal anoxia during storage. PP is compared with PAP to evaluate the relative reliability of PAP. Sixty female Landrace pigs were used for 30 OLTs. Group 1 livers underwent PP, whereas group 2 livers were treated with PAP. The cold ischemic time was less than 120 minutes for both groups, with no warm ischemia. Intraoperative and 24-hour postoperative biochemical, coagulation, and histocytological data were analyzed. Morphological studies of cellular damage were based on the percentage of CVD and KP and classified as light, moderate, and severe damage. Data, at closing, were compared by using Fisher's test (group 1 v group 2,P = 0.003 for light damage and P = .04 for severe damage; first postoperative day for group 1 v group 2, P = .133 for light damage and P = .25 for severe damage. Blood samples at closing and 24 hours postoperatively showed significant differences between groups 1 and 2: At closing for groups 1 and 2, respectively: AST, 968.9 +/- 742.7 and 327.4 +/- 174.7 IU/L (P less than .001); ALT, 63.1 +/- 40.3 and 20.3 +/- 5.3 IU/L (P less than .001); AP, 292.2 +/- 107.1 and 139.5 +/- 45.3 IU/L (P less than .001); and 24 hours postoperatively for groups 1 and 2, respectively: AST, 1,664.9 +/- 917.8 and 419.3 +/- 230.9 IU/L (P less than .001): ALT. 180.4 +/- 28.9 and 66.4 +/- 17.5 IU/L (P less than .001); AP, 602.1 +/- 153.3 and 255.7 +/- 116.3 IU/L (P less than .01). Comprehensively, the results reflect a better perfusate distribution of the PAP livers compared with PP ones: uniform organ preservation, faster metabolic recovery, and reduced postoperative mortality.

The anti-CD30 immunotoxin (IT) Ber-H2/saporin is effective in patients with refractory Hodgkin's disease. However, responses are short and partial, one of the main reasons being the inability to repeat IT doses because of formation of human antibodies against the murine antibody and/or the toxin. To overcome this problem, we constructed two new anti-CD30 ITs by covalently linking the mouse monoclonal antibody Ber-H2 to the type 1 ribosome-inactivating proteins (RIPs) momordin (MOM) and pokeweed antiviral protein from seeds (PAP-S), which do not cross-react with each other or with saporin. Both ITs inhibited protein synthesis by Hodgkin's disease and anaplastic large-cell lymphoma (ALCL)-derived CD30+ target cell lines with a very high efficiency (IC50 ranging from < 5 x 10(-13) M to 2.75 x 10(-11) M, as RIP). In a SCID mouse model of xenografted CD30+ human ALCL, a 3d treatment with non-toxin doses of Ber-H2/MOM (50%LD50), started 24 h after transplantation, prevented tumour development in about 40% of the animals and significantly delayed tumour growth rate in the others. Main toxicity signs in mice and rabbits were dose-related increase of serum transaminases (AST and ALT) and creatine phosphokinase (CPK). LD50 (as RIP) in Swiss mice was 7 mg/kg for Ber-H2/MOM and 0.45 mg/kg for Ber-H2/PAP-S. Sequential administration of two anti-CD30 ITs (Ber-H2/MOM and Ber-H2/saporin) was well tolerated and did not result in formation of antibodies cross-reacting and with the two plant toxins. The results presented in this paper suggest that in the future, sequential administration of anti-CD30 humanized antibodies linked to antigenically distinct type 1 RIPs (saporin, MOM, PAP-S) should be feasible.
