OBJECTIVES: The aims of this study were to evaluate the interaction of topotecan with adriamycin, etoposide, 5 fluorouracil (5 FU) and mitomycin C in the established four ovarian cancer cell lines and three cervical cancer cell lines and to establish whether the combination of topotecan with other antitumor drugs would be a synergism for chemotherapy in patients with ovarian and cervical cancer, METHODS: Five antitumor drugs were tested for synergism and antagonism in combination studies in four ovarian cancer cell lines (A2780, A2780 cisplatin resistant variant, A2780 taxol resistant variant, SKOV3) and three cervical cancer cell lines (HeLa, SiHa, ME180). Cytotoxic effects were determined by MTT assay. Synergic interaction was calculated by the median effect principle in which combination index (CI) of less than one suggest a synergic interaction. RESULTS: Dm value of topotecan against SKOV3 (2.07 ug/ml), HeLa (3.32 ug/ml), SiHa cell lines (2.5 ug/ml) were above peak plasma concentration of topotecan (0.5 ug/ml) but most antitumor drugs tested in combinations index were within clinically relevant range. Combination with topotecan showed a synergic effect (CI<1) in seven cancer cell lines at a intermediate or high level of cytotoxicity especially with mitomycin C (6/7), etoposide (6/7), 5 FU (6/7) and adriamycin (4/7). Most striking findings were that a synergic effect was shown in all ovarian cancer cell lines to topotecan/mitomycin C, topotecan/5 FU and topotecan/esoposide combination showed a synergic effect in all cervical cancer cell lines. Topotecan/adriamycin combination showed synergism at an intermediate or high level of cytotoxicity in cisplatin or Taxol resistant ovarian cancer cell lines (A2780CP, A2780TX, SKOV3). CONCLUSION: These results suggested that topotecan showed a synergic effect with a wide range of antitumor drugs: adriamycin, etoposide, 5 FU, mitomycin C in ovarian and cervical cancer cell lines. Combinations of topotecan/mitomycin C, topotecan/5 FU and topotecan/adriamycin for ovarian cancer and a combination of topotecan/etoposide for cervical cancer seemed worthy of consideration for clinical application.

Clinical and pathological studies were carried out on 78 patients of ovarian cancer from January 1985 to March 1991. The results are as follows : l. Among 78 patients of ovarian cancer, the age group from 51 to 60 years old was most common which was 18 cases(23.1%). 2. When classified according to the cell type, epithelial cell origin cancers were 59 cases (75.6%), ovarian cancers from germ cell origin 9 cases(11.5%), sex cord stromal cancers 3 cases(3.8%), and metastatic cancers 7 cases(8.9%) respectively. 3. When classified according to the FIGO staging, stage I were 34 cases(43.5%), stage II 8 cases(10.3%), stage III 23 cases(29.5%) and stage IV 13 cases(16,7%), respectively. 4. Preoperative mean CA 125 value of stage I ovarian cancer was 130.2+/-57.3U/ml, stage II 74.2+/-144.4U/ml, stage III 376.9+/-296.8U/ml and stage IV 433.9+/-148.2U/ml respectively. and Also preoperative mean CEA value of stage I ovarian cancer was 3.4+/-3.2ng/ ml, stage II 6.9+/-4.3ng/ml, stage III 4.7+/-4.4ng/ml and stage IV 4.6+/-6.3ng/ml respectively. 5. When classified according to the physical examination, the most common finding was palpable mass which were 38 cases(43.7%), the second, abdominal pain 30 cases(38.4%) and the third, abdominal distension 21 cases(26.9%) 6. When classified according to the operation, ipsilateral oophorectomy was 15 cases(25.5%), ipsilateral oophorectomy and contralateral ovary wedge resection 6 cases(10.2%), total abdominal hysterectomy 17 cases(28.8%), total abdominal hysterctomy and omentectomy 14 cases(23.7%), total abdominal hysterectomy and omentectomy and debulking tumor resetion 4 cases(6.7%) and biopsy only 3 cases(5.1%) respetctively. 7. When calssifide according to the postoterative endometrial finding, atrophic pattern was 28 cases(65.7%), proliferative pattern 10 cases(28.6%) and secretory pattern 2 cases(5.7%) respectively.

Direct contact method of autoradiography was utilized in studying the distribution of exogenous C(14)-proline in Clonorchis sinensis, Eurytrema pancreaticum, Hymenolepis diminuta and Dipylidium caninum. The most distinct autoradiogram were obtained after 60 min of incubation, corresponding to the maximal absorption of C(14)-proline in these parasite. The radioactivitity of this labeled amino acid was chiefly concentrated in reproductive organs, especially egg-containing uterine tubules.

Congenital hepatic fibrosis is an inherited, congenital disorder of the liver, and is occasionally associated with cystic disease of the liver and kidney. We present a case of congenital hepatic fibrosis with Caroli's disease. A 21-year-old woman had suffered from an episodic fever with headaches for 3 years. In laboratory examination, the liver function test was within the normal limits. Esophageal varix was noted by an endoscopic examination. Hepatosplenomegaly and multiple dilated bile ducts were seen by abdominal CT scanning. An orthotopic whole liver transplantation was done. The liver was fibrotic and enlarged. Multiple cystically dilated intrahepatic ducts were noted. Microscopically, diffuse portal fibrosis and widening with proliferation of bile ductules were seen. Intrahepatic bile ducts were markedly dilated and tortuous. The liver cell cords were well preserved.
