Soluble part of
hepatocellular carcinoma
(
HCC
) tissue extracts with or without hepatitis B surface antigen (HBsAg) was tested against leukocytes of 13 histologically confirmed
HCC
patients. Inhibition of leukocyte migration was observed in 9 out of 13 cases when tested by soluble
HCC
extract containing HBsAg, while inhibition of lukocyte migration was observed in 8 out of 13 cases when tested by solublp greater than 0.05, by Fisher's exact test). In the meantime, soluble
HCC
extract with or without HBsAg did not significantly cause inhibition of leukocyte migration in 12 non-
HCC
patients. Therefore, it is concluded that inhibition of leukocyte migration in
HCC
patients is caused by the tumor-associated antigen, not caused by HBsAg.

Reaction of the trimethylsilyl derivative of 2,3-dihydro-6H-1,3-oxazine-2,6-dione (2, "uracil anhydride") with protected 1-O-acetylribofuranoses in the presence of stannic chloride gave the corresponding block nucleosides. 3-(2,3-5-Tri-O-2',2',2'-trichloroethoxycarbonyl-beta-d-ribofuranosyl)-2,3-dihydro-6H-1,3-oxazine-2,6-dione (4c) thus prepared from the protected sugar 3c, 1-O-acetyl-2,3,5-tri-O-(2,2,2-trichloroethoxycarbonyl)ribofuranose, gave, on removal of the protecting groups with zinc dust,3-(beta-d-ribofuranosyl)-2,3-dihydro-6H-1,3-oxazine-2,6-dione (1). The structure of 1 was confirmed by uv, ir, NMR, and CD spectral data and was shown to be an N nucleoside. Uracil anhydride, 2, and, to a lesser extent, its
ribonucleoside
1 exert a moderate growth inhibition of mouse leukemia L5178Y, HeLa, and Novikoff
hepatoma
cells i- culture. Both compounds produce weak inhibition of vaccinia viral replication in HeLa cells.

When soluble
hepatocellular carcinoma
(
HCC
) extract prepared by 3 M KCl solution was passed through a column of Sephadex G-200, four fractions (designated as I, II, III, IV) could be obtained from the elution profile. By leukocyte migration inhibition assay, the active component of soluble
HCC
extract which represented tumor-associated antigen was shown to be contained in fractions I and II.

Recombinant interleukin-2 (rIL-2) and adriamycin were administered systemically to treat nine patients (age 15.5-68 years, mean 48.9 years) with far advanced primary
hepatocellular carcinoma
. Three patients were newly diagnosed, and the remaining patients had received surgery, transcatheter arterial embolization, chemotherapy and other treatments but without improvement. RIL-2 was given at a dose of 10,000 to 30,000 units/kg every 8 hours for consecutive 9 days, and on the fifth day, a single dose of adriamycin 30 to 60 mg/M2 was administered. Four patients interrupted the immunotherapy because of severe intolerable side effects, 4 patients completed one course and the remaining one received 2 courses of treatment. Various adverse reactions were encountered, however, they subsided promptly after stop of therapy. All patients failed to respond to the regimen. Primary hepatic tumors continued to enlarge in 8 patients and remained unchanged in one, and pulmonary metastases also increased in size and number in 4 patients. Transient decrease in serum alpha-fetoprotein was found in 6 patients. These results suggests that systemic IL-2 immunotherapy, even in combination with chemotherapy, is not effective for the treatment of far advanced
hepatocellular carcinoma
. However, in viewing of its immune amplifying effect, rIL-2 in combination with other treatment modalities may still be worth trying in early stages of
hepatocellular carcinoma
.

The prevalence of antibodies to hepatitis C virus (anti-HCV) was investigated among different populations in Taiwan, where anti-HCV was detected in 0.8% (24/2,994) of adult volunteer blood donors, 0.1% (1/1,305) of youngsters and children, 12.5% (8/64) of adult volunteer blood donors with elevated alanine aminotransferase (ALT), 36.5% (23/63) of hemodialysis patients, 4.1% (13/318) of male homosexuals, 25.4% (16/63) of cases positive for antibodies to human immunodeficiency virus (anti-HIV), 82.2% (578/703) of intravenous drug users (IVDUs), and 10.3% (23/223) of female prostitutes (FPs). Among patients with chronic liver diseases including chronic hepatitis, cirrhosis and
hepatocellular carcinoma
(
HCC
), the overall prevalence rate for anti-HCV was 34.1% (42/123), and a higher prevalence was noted in hepatitis B surface antigen (HBsAg)-negative cases than in HBsAg-positive cases. The prevalence of anti-HCV in volunteer blood donors and high prevalence found in IVDUs, hemodialysis patients, anti-HIV positive cases, and FPs are consistent with those results from other countries. These findings suggest that hepatitis C virus (HCV) infection is transmitted by both blood-borne and sexual contact routes. Among flavivirus infections, anti-HCV was detected in 0.3% (1/289) and 1.3% (4/310) of Japanese encephalitis and dengue fever patients, respectively. In conclusion, in Taiwan, an area with high endemicity of hepatitis B virus (HBV) infection, the epidemiological status of HCV infection is similar to that observed in other countries, and no serum cross-reactivity was noticed between HCV and flavivirus infections.

A new murine monoclonal IgG3 antibody (Mab 1H10) was developed with specificity for human cervical carcinoma and several other tumor types. Antibody reactivity against a panel of tumor cell lines was examined by indirect immunofluorescence and quantified by flow cytometry. Mab 1H10 reacted with cervical, colorectal and bladder carcinoma cells and to a lesser extent melanoma and
hepatocellular carcinoma
cells but did not react with human fibroblasts, lymphocytes or RBCs. Mab 1H10, as assessed by immunohistochemical staining, bound 40/97 cervical carcinoma tissue samples, 8/16 colorectal carcinoma samples as well as a population of osteogenic sarcoma and lung, ovarian and bladder carcinoma tissues. Mab 1H10 did not react with any normal tissue or cell samples tested including cervix, ovary, breast, liver, colon, bladder, lung, spleen, cerebrum, lymphocytes or RBCs. Mab 1H10 may be useful for the targeting of drugs, toxins or radioisotopes to cervical carcinoma in humans.

A panel of seven murine monoclonal antibodies reactive with human
hepatocellular carcinoma
(
HCC
) cell line, SK- HEP-1, resulted in the definition of four distinct antigen systems, designated HB4, HB5, HB1 and HJ2. HB4 antigen was found to be expressed specifically on
HCC
cell lines and fresh
HCC
specimens but not on normal liver. Immunoprecipitation tests suggest that the HB4 epitope may be a heat-stable carbohydrate determinant on a high molecular mass molecule. HB5 antigen was found to have less-restricted expression on a panel of normal adult tissues and on melanoma, astrocytoma, sarcoma, neuroblastoma and epithelial cancer cell lines. In fetal and adult liver, HB5 antigen localized to bile canaliculi and ducts. Under reducing conditions, three mAbs detected a Mr 140,000 glycoprotein using lysates of [125-I], [3-H]-glucosamine and [35-S]-methionine labeled SK-HEP-1 cells. Under non-reducing conditions an additional component of greater than Mr 200,000 was also detected. HB1 antigen was found on almost all monolayer cell lines and not on most cultured suspension cells. This antigen was also detected on cultured
HCC
cells inoculated into nu/nu mice. Immunoprecipitation experiments revealed that the HB1 antigen is a bimolecular complex with an Mr 170,000 alpha chain and Mr 130,000 beta chain under non-reducing conditions, and three subunits of Mr 140,000, Mr 30,000 and Mr 130,000 under reducing conditions. Two antibodies reacted with epitopes on the alpha chain. HJ2 antigenic determinant is a heat-stable component which could not be immunoprecipitated. This most widely expressed antigen was found in secreted form in many of the cells and tissues examined. These antibodies introduce new antigens which may serve as useful markers for the diagnosis, classification and investigation of
HCC
and other liver diseases.

Two monoclonal antibodies, designated 4C4 and 4G1, were produced by immunization of BALB/c mice with a human esophageal carcinoma cell line, CE69T/VGH, followed by fusion of the spleen cells from an immunized mouse with myeloma cells NS-1. 4C4 showed strong binding activity to three human esophageal carcinoma cell lines and one human
hepatoma
cell line, but not to any other cell lines tested. 4G1 reacted with three human esophageal carcinoma cell lines and four other cell lines. By peroxidase-antiperoxidase staining, 4C4 and 4G1 detected antigens of the epithelial cells on 10 pairs of esophageal carcinoma and normal esophageal specimens. 4G1 recognized a CE69T/VGH antigen with a molecular weight of 180K. Since 4G1 also reacted with purified carcinoembryonic antigen (CEA) and immunoprecipitated 125I-CEA, 4G1 seems to be an antibody recognizing CEA produced by CE69T/VGH cells. Since 4C4 also bound to the epithelial cells of normal uterine, vaginal, breast and liver tissues, it seems to recognize an epithelial antigen, and can be used to characterize the antigen in the specialization or differentiation of epithelial cells.

The expression of 20 known cellular proto-oncogenes in human well-differentiated
hepatoma
cell line Hep3B and poorly-differentiated
hepatoma
cell line HA22T/VGH was studied by Northern blot hybridization. Among the cellular proto-oncogenes examined, both cell lines express protein kinase genes including fps, mos and raf; PDGF B chain sis gene; GTP/GDP binding protein gene Ha-ras and nuclear protein genes including fos and myc. The expression of yes, abl, ros, src, erb-B, erb-A, fms, Ki-ras, myb, rel and bas genes was not detected in both cell lines.

This study included 16 histologically confirmed hepato-cellular carcinoma (HCC) patients. At the same time, 32 normal healthy individuals and 20 asymptomatic hepatitis B surface antigen (HBsAg) carriers were served as control groups. The study disclosed that T cells, OKT4 cells and the ratio of OKT4 cells/OKT8 cells in peripheral venous blood of HCC patients before surgery were lower than that of either normal control or asymptomatic HBsAg carriers. The difference was statistically significant. The T cells, OKT4 cells and the ratio of OKT4 cells/OKT8 cells of 4 HCC patients with positive HBeAg did not show further decrease as compared with that of 12 HCC patients with negative HBeAg. Periodic examination of T cells, OKT4 cells and OKT8 cells in 16 HCC patients after surgical removal of
hepatocellular carcinoma
tumor revealed that preoperative depressed T cells will decline further in the first postoperative week, but it will gradually increase to near normal range in the fourth or fifth postoperative week. However, OKT4 cells still remained in depressed state during the postoperative observation period. In the conclusion, it has been suggested that the derangement of T-cell subsets observed in HCC patients is not related to either HBsAg or even HBeAg. It can be either precondition to HCC formation or further follow up period being needed to look for the change of OKT4 cells.
