The aim of the present investigation was to evaluate the effect of A.nilotica extract against Dalton's ascitic lymphoma (DAL) induced solid and ascitic tumors in BALB/c mice. Experimental animals received A.nilotica extract (10 mg/kg.bw) intraperitoneally for 10 and 14 consecutive days before induction of solid and ascitic tumors, respectively. Treatment with A.nilotica extract significantly decreased the development of tumor and percentage increase in body weight when compared to DAL induced solid tumor control group, also increasing the life span, restoring the total white blood cell count and hemoglobin content and significantly decreasing the levels of serum aspartate transaminase (SGPT), alanine transaminase (SGOT), alkaline phosphatase (ALP), gamma glutamyl transferase (GGT) and nitric oxide (NO) when compared to DAL induced ascitic tumor controls. The treatment also reduced significantly the cellular glutathione (GSH) and nitric oxide levels in treated animals. Histopathological studies also confirmed protective influence. The outcome of the present work indicates that A.nilotica extract could be used as natural anticancer agent for human health.

Cytodiagnosis of pleural and ascitic fluid is a commonly performed laboratory examination. Especially, positivity for malignant cells in effusion cytology is very effective and also presents the first sign of malignancy in unknown primary site of the tumor. We examined each 34 cases of pleural and ascitic fluid cytologic specimen diagnosed as metastatic tumor, which was selected among 964 pleural fluid cytology cases and 662 ascitic fluid cytology cases from September 1989 to June 1995. Among the pleural fluid cytology specimens examined, 34 specimens were positive in 27 patients. The lung was the most frequent primary site(44%), followed by the stomach (12%), lymphoreticular neoplasm(12%), pancreas(3%) and colon(3%). And the cases of unknown primary site with positive pleural biopsy alone were 24%. Among trio ascitic fluid cytology specimens examined, 34 specimens were positive in 29 patients. The most common primary neoplasms. were carcinomas of ovary(32%), stomach(22%), colon(6%), breast(3%), pancreas(3%), and lung(3%) and lymphoreticular neoplasms(3%) The metastatic tumor was predominantly adenocarcinoma type in both pleural(82%) and ascitic(91%) fluid. The study of metastatic adeno- carcinoma in effusion from lung, ovary, and stomach was undertaken to find distinctive features for the identification of the primary site. The smears of metastatic pulmonary adenocarcinoma had a tendency to show high grade pleomorphism and many large tight cell clusters, whereas that of the ovarian adenocarcinoma showed low grade pleomorphism with abundant intracytoplasmic vacuoles in relatively clear background. That of the stomach revealed the intermediate features.

The pine needles, Pinus densiflow Sieb. et Zucc., which is a feed for goats showing a low incidence rate of cancer were evaluated to confirm the potent anticancer effects, with or without several conventional anticancer drugs. The pine needles collected from Mt. Buk-Han located near Seoul were extracted with 95% methanol and methand and concentrated. From the methanol extract, SOM-A, was extracted dichlormethane and SOM-B was extracted with ethyl acetate. SOM-C was extracted with distilled water. These extracts were tested for their antitumor activities in vitro and in vivo. Among them, SOM-A and SOM-C exhibited potent antitumor activities described as belows. 1. The cytotoxic effects of SOM-A and SOM-C were examined against in vitro cultured murine and humman tumor cells. SOM-A showed strong cytotoxicity against human tumor cell lines and SOM-C showed strong cytotoxicity against murine tumor cell lines tested. 2. The antitumor effects of SOM-A and SOM-C were examined against P388 and L1210 of mouse ascitic tumors. The highest mean survival time(MST) ration was 151%(P388) for SOM-C(90mg/kg). 3. To compare the antitumor effects of SOM-A, SOM-B, and SOM-C against solid tumors, S-180 and Ehrlich carcinoma were implanted subcutaneously to mice on Day O. The drugs were given intraperitoneally to mice once a day on Days 1-20, and the tumor weights were measured on Day 21. SOM-A showed inhibition of tumor growth more than 50% in the experiment on S-180 and Ehrlich, and SOM-C also markedly inhibited tumor growth. However, SOM-B had no effect. 4. SOM-C combined with ${\alpha}$-interferon and SOM-C combined with Mitomycin-C enhanced the antitumor activities against murine ascitic tumors P388 leukemia.

Antitumor effect of LC43, a protein-bound ploysaccharide (M.W. 43 kDa) that was purified from intergeneric protoplast fusant of Lentinus edodes and Coriolus versicolor, was elucidated against mouse sarcoma 180 cell in vitro and in vivo. By injecting LC43 into ICR mice bearing solid or ascitic sarcoma 180, tumor regression and survival rates were investigated. To examine the effects of LC43 on immunopotentiation activity. immunoorgan weight, B cell differentiation, T cell activity and macrophage activation were determined. LC43 showed antitumor effects against both solid tumor and ascitic tumor of sarcoma 180. It did not change significantly the immunoorgan weight but potentiated immune responses such as B cell differentiation and the release of superoxide anion from macrophages. These results suggest that the protein-bound polysaccharide of LC43 exhibited antitumor activities through the activation of immune-related cells and acted as an immunmodulator.

The cytologic findings of endodermal sinus tumor of the ovary are reported. The cytologic preperations were obtained from ascitic specimens. The findings on Papanicolaou-stained smears included a clean background and poorly preserved atypical cells loosely arranged in irregular or papillary groups. At high magnification, the cells had ill-defined and microvacuolated cytoplasms, with an increased nuclear-cytoplasmic ratio and prominent nucleoli. Hyaline globules characteristic of the alpha-fetoprotein (AFP)-synthesizing cells of endodermal sinus tumor were observed within the cells with periodic-acid-Schiff(PAS) stain. The presence of PAS-positive hyaline globules can be regarded, therefore, as a diagnostic clue to endodermal sinus tumor in an appropriate clinical setting and in the presence of AFP production. The cytologic findings in a cell block is important, in addition to smears, to obtain more diagnostic clues. A preliminary cytomorphologic diagnosis of this highly malignant tumor is valuable as a guide in planning further immunocytochemical and serologic studies.

We experienced a case of infiltrating lobular carcinoma of the breast in the ascitic fluid. The patient was a 49 year-old woman who presented with a palable mass of 3 months duration in the left upper quadrant of the abdomen and abdominal distension. Five years ago, she had undergone left radical mastectomy with chemotherapy and radiotherapy for infiltrating lobular carcinoma of the breast. The ascitic fluid smears revealed singly scattered small round to elliptical cells, many of which were arranged in characteristic indian-file patterns consisting of 3 to 5 cells. The tumor cells had scanty cytoplasm, rare cytoplasmic vacuoles and marked chromatin clumping with small, but prominent nucleoli.

T-cell prolymphocytic leukemia (T-PLL) is a rare, mature T-cell lymphoproliferative disorder with a post-thymic mature T-cell phenotype. The disease is characterized by rapidly rising lymphocytosis, lym-phadenopathy, and splenomegaly. The clinical course is usually aggressive and progresses with frequent skin lesions and serous effusions. In 25% of cases, leukemic cells are small and tumor cells may not have a discrete nucleolus under light microscopy. Although the presence of characteristic cytoplasmic protrusions or blebs in tumor cells is a common morphologic finding in the peripheral blood film irrespective of the nuclear features, small cell variants lacking the typical nuclear features can cause diagnostic problems in clinical cytology. Furthermore, the small leukemic cells can share some cytologic findings with lymphocyte-rich serous effusions caused by non-neoplastic reactive lymphocytosis as well as other small lymphocytic lymphoproliferative disorders. Here, we describe the cytological findings of ascitic fluid complicated by small cell variant T-PLL in a 54-year-old man, the cytology of which was initially interpreted as small lymphocytic malignancy such as small lymphocytic lymphoma/chronic lymphocytic leukemia.

Various analogues of 5,8-dimethoxy-1,4-naphthoquinone (DMNQ) such as 2- or 6-(1-hydro-xyiminoalkyl)-DMNQs were prepared and evaluated for the antitumor action. (1-Hydroxyiminoalkyl)-DMNQ derivatives expressed greater antitumor action than (1 -hydroxyalkyl)- or acyl-DMNQ derivatives. Moreover, 6-(1-hydroxyiminoalkyl)-DMNQ derivatives expressed higher anti-tumor action than 2-sudstituted ones, suggestive of a steric effect. Some of 6-(1-propyloxyalkyl)-DMNQ derivatives with an alkyl group of butyl to octyl moiety showed T/C values of > 400 %.
