Abstract
OBJECTIVE Choriocarcinoma is a highly invasive gynecologic tumor, and hematogenous metastases frequently develop. To establish a molecular basis for antiinvasion therapy of choriocarcinoma, we examined the effects of human recombinant interferons on gelatinase production and invasion by choriocarcinoma cells. STUDY DESIGN Using five choriocarcinoma cell lines, we measured gelatinase activity by gelatin zymography. The effects of recombinant interferons (rIFN-alpha, rIFN-beta, and rIFN-gamma) were then analyzed by Western blot analysis and chemoinvasion assay. RESULTS High levels of 72 kd gelatinase activity were detected in the highly invasive choriocarcinoma cell lines, two of which also contained an active form of 72 kd gelatinase with an apparent molecular mass of 68 kd. Gelatinase production was decreased by incubation with rIFN-beta. In the chemoinvasion assay, only rIFN-beta had an inhibitory effect on the invasiveness of tumor cells without a cytotoxic effect. CONCLUSION Choriocarcinoma cells showed high 72 kd gelatinase activity, which suggested a role for the enzyme in vascular metastasis. Studies on the use of rIFN-beta to inhibit metastasis of choriocarcinoma via suppression of gelatinase production are warranted.

Abstract
CA125 II, an improved version of the conventional CA125 was compared with CA125 as to which was more useful in gynecologic disease. In the diagnosis of tumors around the adnexal field (primary epithelial ovarian cancer, metastatic ovarian cancer, benign ovarian tumor and endometrial cyst), CA125 II showed the same sensitivity and specificity as CA125. CA125 II also has high simultaneous reproducibility in the low concentration area. The examination by the receiver operating characteristic curve revealed that CA125 II has higher precision than that of CA125 when it is used for the screening test. In conclusion, CA125 II is a better tumor marker than conventional CA125.

Abstract
Human ovarian carcinoma cells (HRA) were sensitized to cis-diammine(1,1-cyclobutanedicarboxylato)platinum(II) (CBDCA) 1.2-, 2.1- and 3.4-fold by treatment with amphotericin B (AMB) at concentrations of 2.1, 5.4, and 10.8 microM, respectively. Moreover, the intracellular accumulation of platinum after 2-h exposure to CBDCA was increased significantly by AMB treatment. For estimating the enhancing effect of AMB on CBDCA cytotoxicity in vivo, we prepared HRA cell-inoculated nude mice. Ascites was evident 7 to 9 days after intraperitoneal (i.p.) inoculation of HRA cells, and the mice died of intraabdominal carcinomatosis 11 to 14 days (mean survival time (MST): 12.0 +/- 1.0 days) after inoculation. Treatment with AMB (2.0 mg/kg) alone increased the MST by only 1.2 days. Simultaneous treatment with CBDCA (12 or 15 mg/kg) and AMB (0.5 to 2.0 mg/kg) produced a significant increase in MST compared to treatment with CBDCA alone. Maximal MST (38.5 days) was obtained by treatment with 15 mg/kg CBDCA plus 2.0 mg/kg AMB, whereas the MST with 15 mg/kg CBDCA alone was 15.8 days. A drug accumulation study demonstrated that platinum accumulation in tumor tissues after i.p. treatment with CBDCA and AMB in tumor-bearing nude mice was increased significantly compared to treatment with CBDCA alone. These findings indicate that intraperitoneal combination chemotherapy with CBDCA and AMB is useful in nude mice with advanced ovarian carcinoma.

Abstract
The expression of antigens on rat hepatocytes was examined by immunoelectron microscopy using monoclonal antibody HAM 1. The antigen recognized by HAM 1 was expressed mainly on both sinusoidal and bile-canalicular faces and only sparsely on the contiguous face. All rat hepatoma cell lines examined were intensely labeled with HAM 1, but poorly labeled with HAM 3, HAM 4, and HAM 5, as revealed by flow cytofluorometry and radioimmunoassay. Expression levels of HAM 1 antigen on the AH 44 hepatoma cell line similar to the degree seen in normal liver were demonstrated by radioimmunoassay. HAM 1 antigen was also expressed weakly on lymphocytes, thymocytes, and some bone marrow cells, but not on red blood cells, and differed from the MHC class I antigen recognized by HAM 2 and OX 18. Significant amounts of cell surface antigens recognized by all the monoclonal antibodies (HAM 1-HAM 5) were confirmed by radioimmunoassay on the cell surface of primary cultured hepatocytes. These results suggest that the rat hepatoma cell lines employed are different from normal hepatocytes, that primary cultured hepatocytes are more similar to normal hepatocytes in the degree of expression of their cell surface antigens, and that HAM 1 antigen appears to be a significant antigen on both normal and transformed hepatocytes.

Abstract
To investigate the clinical significance of transvaginal color-pulse Doppler sonography in ovarian tumors, 109 patients were examined at Nagoya University Hospital. Ultrasonographic patterns were classified and the levels of three circulating tumor markers, CA125, CA72-4, and CA19-9, were simultaneously evaluated. In differentiating benign and malignant ovarian tumors, transvaginal color-pulse Doppler and ultrasonographic pattern classification were superior to the tumor markers. Of 49 cases with benign pattern, 45 were benign (91.8%). Of 60 cases with malignant pattern, 24 (40%) were benign and 36 (60%) were malignant or borderline malignant. In this group color-pulse Doppler sonography was the most useful procedure, and sensitivity, specificity, and accuracy were 75.0, 79.2, and 76.7%, respectively. Menopausal status and site of the arterial wave form in the tumor were also important. Transvaginal color-pulse Doppler sonography was a reliable diagnostic method for differentiating ovarian tumors.

Abstract
OBJECTIVE Our purpose was to evaluate type IV collagenase in ovarian and endometrial cancer tissues. STUDY DESIGN Tissue specimens were obtained from patients with ovarian and endometrial cancer and uterine myoma. Gelatinase activity was detected by zymography and quantitated by densitometer. RESULTS Four dominant gelatinases were detected in ovarian and endometrial cancer tissues: 200, 130, 92, and 72 kd gelatinase. Other forms observed were 83 kd gelatinase, which is an active form of 92 kd gelatinase, and 66 kd gelatinase, which is an active form of 72 kd gelatinase. Densitometric analysis showed that the 92 kd/72 kd ratio in ovarian cancer tissues was significantly higher than in normal ovarian tissues (p < 0.05) and that the 66 kd/72 kd ratio was higher in ovarian cancer tissues (p = 0.07). Both ratios in endometrial cancer tissues were significantly higher than in normal endometrial tissues (p < 0.05). CONCLUSION Gelatinase activity was remarkably higher in ovarian and endometrial cancer tissues. Especially, 92, 83, and 66 kd gelatinases were clearly detected in cancer tissues, suggesting that these gelatinases were related to the malignant phenotype, because degradation of the components of the basement membrane such as type IV collagen is necessary for cancer cells to metastasize.

Abstract
The level of a bile canalicular membrane antigen in serum during extrahepatic cholestasis was serially analyzed using HAM.4, a monoclonal antibody against a bile canalicular membrane glycoprotein of normal rat hepatocytes. After bile duct ligation, the level of HAM.4 antigen in serum promptly increased within 1 hr, reached a maximum at 3 hr, and declined somewhat until 48 hr, where it plateaued. Elevated levels of HAM.4 antigen in serum preceded those of well-known biliary marker enzymes activities. Immunohistochemical studies showed that the expression of HAM.4 antigen in hepatocytes and bile duct cells was not altered appreciably after bile duct ligation even when HAM.4 antigen in serum reached a maximal level. The serum and hepatic HAM.4 antigen had a molecular weight of 110 kDa. These results suggest that HAM.4 antigen may be regarded as a potential marker of the early stage of cholestasis, with release occurring before apparent histological changes.

Abstract
Human ovarian carcinoma cells (HRA) were sensitised to cis-diamminedichloroplatinum (II) (CDDP) 2.7-, 5.5- and 12.1-fold by treatment with amphotericin B (AMB) at concentrations of 2.1, 5.4 and 10.8 microM, respectively. Moreover, intracellular accumulation of platinum after a 2-h exposure to CDDP was increased significantly with AMB treatment. We prepared HRA cell-inoculated nude mice as an experimental therapeutic model for human advanced ovarian carcinoma. Ascites was evident after 7 to 9 days of intra-peritoneal (i.p.) inoculation of HRA cells, and mice died due to intra-abdominal carcinomatosis after 11 to 14 days [mean survival time (MST): 12.4 +/- 1.1 days]. Treatment with AMB (2.0 mg/kg) alone 4 days after inoculation increased MST by only 1.4 days. Simultaneous treatment with CDDP (1.0 to 2.0 mg/kg) and AMB (0.5 to 2.0 mg/kg) produced a significant increase in MST compared to treatment with CDDP alone. Maximal MST (30.1 days) was observed by treatment with 2.0 mg/kg CDDP plus 2.0 mg/kg AMB, whereas MST with 2.0 mg/kg CDDP alone was 16.4 days. A further drug accumulation study demonstrated that platinum accumulation in tumour tissues in nude mice treated with CDDP and AMB increased significantly compared to treatment with CDDP alone. These results indicate that intraperitoneal combination chemotherapy with CDDP and AMB is effective in an experimental animal model of advanced ovarian carcinoma.

Abstract
One hundred and eighty-eight patients with epithelial ovarian carcinoma were treated with primary cytoreductive surgery and subsequent combination chemotherapy. The first recurrent findings such as sites and disease-free interval were analyzed in 141 patients who were clinically remitted 6 months after operation or chemotherapy. Fifty-seven cases had a recurrence. Five-year disease-free survival rates were 75, 72, 29, and 0% in stage I, II, III, and IV, respectively. Twenty-one of 22 patients with > 2 cm maximum residual tumor died, although they once achieved clinical remission. Significant differences were observed between histologic types, and the disease-free survival rate was lowest for serous cystadenocarcinoma. Nine of 15 stage IV patients with serous histology experienced remission, but none of the 8 in stage IV with other histologies did so, suggesting that serous adenocarcinoma is sensitive to chemotherapy and conducive to clinical remission. However, all stage IV patients in remission encountered a recurrence. Intra-abdominal cavity and lymph node were frequently the initial recurrent sites (38 and 27%, respectively). On the other hand, the incidence of distant recurrence was as high as 27%, and 8 of 16 cases with distant recurrence were stage I. Survival time after recurrence was not different among initial sites of recurrence and mean survival time was 15 months.

Abstract
We have determined an effect of amphotericin B (AMB), an antifungal drug, on the cytotoxicity of cis-diamminedichloro-platinum (II) (CDDP) and 4 CDDP analogues in a human ovarian carcinoma cell line (NOS2). Intracellular accumulation of CDDP was elevated significantly by treatment with AMB, and AMB significantly potentiated the cytotoxicity of CDDP by MTT assay. Intracellular accumulation of 4 CDDP analogues was also elevated by the treatment with AMB and the order of increasing accumulation rate of platinum drugs was consistent with that of dose modification factor (DMF). AMB also increased the intracellular CDDP accumulation in CDDP resistant cells (NOS2CR), derived from NOS2. The intracellular accumulations of 4 CDDP analogues were elevated slightly by the treatment with AMB in NOS2CR cells. DMFs of 5 platinum drugs in NOS2CR cells, however, were more than those in NOS2 cells. These results indicate that AMB sensitizes NOS2 and NOS2CR cells to platinum drugs, partially due to the increasing intracellular accumulation of these drugs. In addition, CDDP analogues are more effective in NOS2CR cells than CDDP, but the cytotoxicity of CDDP was most potentiated by AMB among the 5 platinum drugs under study.

Abstract
The localization of surface antigens and the binding activity of two monoclonal antibodies, HAM2 and HAM4, which recognize the rat major histocompatibility complex (MHC) antigen class I and the rat hepato-renal antigen respectively, on dissociated (free) hepatocytes was examined by light (LM) and electron microscopy (EM), and by radioimmunoassay (RIA). Fixed hepatocytes, fixed before dissociation, and fresh hepatocytes, dissociated by collagenase, were treated by direct staining with HAM2- or HAM4-immunogold complexes (HAM2-gold and HAM4-gold). Some of the directly stained hepatocytes were further mixed with antimouse IgG-gold complex (IgG-gold) to supplement the direct staining. The polarity of the sinusoidal and contiguous faces and the bile canaliculus, i.e. the in situ morphology, was well preserved in the fixed hepatocytes, while the fresh cells had lost the polarity and were round. On the fixed hepatocytes HAM2-gold particles were distributed predominantly on the sinusoidal face, while HAM4-gold particles were localized on both the bile canalicular and sinusoidal faces. No different antigen distribution on the fresh cells was detected with the two antibodies. Supplementation by IgG-gold was noticeable in most cases. The extent of binding activity in both the immunogold and RIA experiments was lower in the fixed cells than in fresh cells. These results suggest that HAM2 and HAM4 are useful monoclonal antibodies for detecting the localization of the MHC class I antigen and the hepato-renal antigen on the hepatocytes, respectively.

Abstract
Hepatocellular carcinomas developed at a high frequency in the livers of transgenic (C57BL/6 X SJL/J)F1 mice under the influence of growth hormone. Three lines of giant transgenic mice expressing a mouse metallothionein-ovine growth hormone fusion gene were generated. The giant mice weighed twice as much as control littermates. The three lines of giant mice expressing very high levels of growth hormone were bred over several generations. Mice from all three lines developed hepatocellular tumors, including adenoma and carcinoma. The occurrence of tumors was age-dependent, and their incidence increased to 70% of the mice studied after 43 weeks of age. Pathologic changes in the livers resembled those observed in rats in which hepatocellular carcinomas are induced chemically. Transgenic mice carrying the metallothionein-ovine growth hormone fusion gene represent a new model for hepatocellular carcinogenesis. This model exemplifies the oncogenic potential for a sustained proliferative growth stimulus within an organ.

Abstract
Changes in the expression of a cell membrane antigen during hepatocarcinogenesis and in the developing liver were analyzed by HAM.4, a monoclonal antibody (MAb) against a membrane glycoprotein of normal rat hepatocyte. Of the precancerous lesions observed during hepatocarcinogenesis induced by diethylnitrosamine, 2-acetylaminofluorene and partial hepatectomy, early neoplastic foci were uniformly stained by HAM.4. In contrast, some cells in the neoplastic nodules at the late stage did not express HAM.4 antigen on the cell surface. Of the cancer tissues, well-differentiated hepatocellular carcinomas were stained by HAM.4 whereas poorly differentiated carcinomas did not bind HAM.4 In developing rat liver, HAM.4 antigen was first expressed on fetal hepatocytes at the 18th day of gestation. It gradually increased until 4 weeks after birth when the intensity of the stain was almost the same as in adult rat liver. These results suggest that the expression of a membrane antigen defined by HAM.4 is closely associated with the differentiation of bile canalicular face and that HAM.4 might be useful in characterizing differentiation of cells during malignant transformation of hepatocytes.

Abstract
Twelve male patients with chronic hepatitis B were treated by the combination of recombinant human alpha-interferon and cyanidanol. They received 3 million units of interferon twice a week and 2,250 mg of cyanidanol daily for 24 weeks. Four patients had sustained clinical improvement in which hepatitis B e antigen and DNA polymerase disappeared from sera and aminotransferase activities fell to normal levels. Elevated pretreatment aminotransferases were associated with the response to therapy. Also, decreased number of OKT4-positive cells prior to treatment were observed among responders. Side effects were minimal and all patients tolerated treatment on an outpatient basis. Twice weekly administration of recombinant leukocyte interferon with cyanidanol may be effective in treating chronic hepatitis when patients are appropriately selected.

Abstract
We have described three monoclonal antibodies (HAM1, HAM2, and HAM3) to rat liver cell membrane glycoproteins. Recently also we reported another monoclonal antibody (HAM4) to rat hepato-renal membrane antigen. Using these monoclonal antibodies, it is possible to purify membrane antigens. This paper describes the details of the purification and the nature of the antigen purified with one of the monoclonal antibodies (HAM2) to rat liver cell membrane glycoproteins. Antigen was purified with immunoaffinity column. The amino acid composition was determined and compared with those of mice MHC class I antigen (H-2) and with the rat lymphocyte membrane antigens which were purified with monoclonal antibodies and of which amino acids compositions were determined.

Abstract
A monoclonal antibody against a membrane glycoprotein of rat hepatocytes has been produced. The nature of this antibody designated as HAM.4 was analysed by cellular radioimmunoassay, flow cytofluorography and indirect immunoperoxidase procedures. The following characteristics of HAM.4 were elucidated. First, an immunohistochemical study revealed that this antibody stained preferentially the bile canalicular face of hepatocyte membrane. Secondly, HAM.4 cross-reacted with kidney, spleen and thymus as well as liver. The kidney expressed much more the antigen molecules detected by this antibody than the liver did. The antigen was located predominantly on the brush border of proximal tubules in kidney. Thus, HAM.4 would be useful for analysing one of the brush border antigens of renal tubules which has been thought to be a pathogenic antigen for inducing experimental membranous glomerulonephritis. Finally, HAM.4 failed to label the cell membrane of rat hepatoma cell lines examined, indicating that the antigen detected by HAM.4 may disappear from cell surface during the course of hepatocarcinogenesis.
