Objectives: The purpose of this study was to report a case of a patient with advanced gastric cancer with peritoneal metastasis treated with chemotherapy and Korean medicine Methods: A patient with advanced gastric cancer with peritoneal metastasis was treated with Xeloda/cisplatin since April 2019. The cycle was repeated every three weeks for a total of 11 times. At the same time, the patient was treated with Korean medicine. The tumor size was measured by computed tomography (CT) and esophagogastroduodenoscopy (EGD). Adverse events were evaluated by the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE), version 5.0. Results: After treatment with Xeloda/cisplatin and Korean medicine for nine months, the extent of the proximal portion of the primary tumor and the size and number of multiple nodules around the stomach decreased and the cancer cells with peritoneal metastasis disappeared. The symptoms of discomfort and physical activity were gradually improved. As a result, the patient underwent conversion surgery. Conclusions: This case study suggests that the combination of chemotherapy and Korean medicine may contribute to the reduction in tumor size as well as the improvement in the quality of life.

Inhibitory effects of cockle extracts on carcinogen-induced cytotoxicity in C3H/10T1/2 cells were studied. Soup (62$\mu\textrm{g}$/mL), solubility (28$\mu\textrm{g}$/mL) and liposolubility (9 $\mu\textrm{g}$/mL) of the cockle inhibited 3-methyl-cholanthrene(MCA)-induced cytotoxicity in C3H/10T1/2 cells by 53 and 94%, respectively. These results suggest that the extracts cockle might have anticarcinogen-induced cytotoxicity of C3H/10T1/2 cells. The effects of cockle extracts on the immune response related to its antitumor activity in vitro and in vivo were investigated. The cockle extracts showed a direct cytotoxic effect on sarcoma-180 cells, tumor cells in vitro. Soup (0.49 mg/mL), solubility (0.11 mg/mL) and liposolubiliy (0.05 mg/mL) of the cockle markedly decreased the total numbers of sarcoma-180 cells, but not their viability. The phagocytic acitivity of peritoneal macrophage of mice was significantly augmented by these extracts of the cockle compared with that of control in vivo. These extracts also raised the phagocuytic index, indicating that the number of phagocytize dmicrobes per macrophage increased. Thus, cockle extracts might show a antitumor activity by enhancing the phagocytic cell activities.

Immunositmulation effects of the mice fed with the cell lysate of Lactobacillus plantarum isolated from Kimchi were studied. The mice group fed with cell lysate was different from the control group on the degree of immune responses, e.g. 1) proliferation of splenocytes and Peyer's patch cells, 2) production of nitric oxide (NO) by peritoneal macrophages, 3) production of intestinal secretory lgA (slgA), 4) variation of TNF-${\alpha}$ and IL-2 concentration in blood, 5) production of specific lgG against sheep red blood cells. A general enhancement in enteric and systemic immune responses was observed with a simple oral administration of immunostimulators. With the oral feeding of L. plantarum, not only the total amount of gut secretion antibody, but also the binding capacity of antibodies to the enteric microorganisms including L. plantarum was increased. These experimental results clearly showed that the oral feeding of immunostimulators gave multifunctional effects on the mucosal and systemic immune systems of mice.

Tetrahymena pyriformis is a free-living ciliate protozoan in the freshwater system. Experiments were carried out to determine whether intraperitoneal administration of T. pyriformis (GL strain) to mice activates macrophages to be able to kill Toxoplasma gondii tachyzoites in vitro. Mice were also injected intraperitoneally with several synthetic activators; dimethyldioctadecylammonium bromide (DDA), dextran sulfate, complete Freund's adjutant (CFA) as well as Toxoplasma and Tetrehymena Iysates in order to activate mouse peritoneal macrophages. One week after the administration of activators, peritoneal cells were harvested and the adherent macrophages were challenged with Toxoplasma tachyzoites. Macrophage monolayers were then fixed with absolute methanol after washing, and stained with Giemsa solution. The percentage of the adherent cells infected and total number of organisms per 100 macrophages were calculated to make toxoplasma-cidal activity of macrophages according to the cultivation time. Peritoneal macrophages from mice administered with Tetrahymena exhibited significant protection against target parasites as compared with those treated with synthetic activators. Among non-biological synthetic activators, DDA was evaluated as an ellcellent activator.

The thymus weight of the mouse was 54.1% in protein malnutritive diet group and 39.2% in group treated with saponin fraction of Panax ginseng in comparison to normal diet group. This decreasing effects of protein malnutritive diet and saponin fraction on the thymus weight practically disappeared after four weeks. The saponin fraction showed no effect on the spleen weight of the mouse. The supplement of the saponin fraction enhanced total peritoneal exudate cells, content of total serum protein and albumin content of the mouse, each 45, 8 and 10% respectively in comparision to that of normal diet group. And these values in protein malnutritive diet group were 61.2, 83.6 and 87.0% respectively in comparision to that of normal diet group, and recovered to the level of normal diet group by the supplement of the saponin fraction. The electrophoregram of the serum protein of the mouse fed with protein malnutritive diet was different from that of the mouse fed with normal diet, but this difference practically disappeared by the supplement of the saponin fraction.

Electro-magnetic fields and static magnetic fields generated from diverse home/environmental sources have been reported that these could make harmful effects on the human health such as suppression of immunity and tumorigenesis. However, the mechanisms for the biologic effects of electro-magnetic fields or static magnetic fields are still remained unclear. In this study, we examined the in vitro effects of static magnetic fields (SMF) on murine peritoneal macrophages. The cells were exposed in vitro to SMF of $150{\sim}250$ or $350{\sim}450$ G in 5% $CO_2$-incubator. The phagocytic activity of murine peritoneal macrophages was inhibited under exposure to SMF. In order to provide a more complete picture of molecular mechanism for the biological effect of SMF, we compared the levels of total proteins from macrophages with or without exposure to SMF using quantitative proteomic analysis. Proteins which were differentially expressed in macrophages exposed to SMF compared with non-exposed macrophages, were identified. Among them, the levels of trypsinogen 16, lactose-binding lectin Mac-2, galactoside-binding lectin, actin-like (Put. ${\beta}-actin$, vimentin) and electron transferring flavoprotein beta polypeptide were enhanced under exposure to SMF. These results suggest that SMF can affect the phagocytic activity of macrophages via diverse mechanisms.

The early gonadal development and sexual differentiation of Rhynchocypris oxycephalus are described from the stage of hatching to 150 days after hatching. During this peroid, the average length of the body grew from 0.64 cm to 5.96 cm. the primordial germ cells (PGCs), which could be recognized at the time of hatching, began to protrude into peritoneal cavity at a standard total length of 1.91 cm. At a standard total length of 2.29cm, initial ovarian differentiation wasidentified by the transformation of PGCs to meiotic oocytes. Finally, at the standard total length of 5.96 cm, the female gonads gradually developed towards migratory nucleus oocytes, characterisiing the maturation. Oocytes proliferated rapidly after sex differentiation while the testis entered a period of quiescence, as they continued to multiply but did not undergo growth until the standard total length of 4.00 cm. At a standard total length of 4.00 cm, spermatocytes arrested in thephase of interkinesis, Sertoli-like cells and sperm duct formation, with signs of meiotic activity, were observed. Therefore it may be concluded that R. oxycephalus belongs to the differentiated type of gonochoristic teleosts.

Polysaccharide fractions were prepared from Forsythia Corea by several different extraction schedules. The fractions obtained were designated as ForCo A, ForCo B and ForCo C respectively. ForCo C was further purified through Sephadex G 200 column chromatography and obtianed two subfractions (Coreana A, Coreana B). ForCo showed marked antitumor activity against sarooma 180 and its activity was dose-dependent. Coreana A, purified from ForCo C, showed somewhat higher antitumor activity. ForCo C increased the number of circulating leucocytes and peritoneal exudate cells, but didn't show any significant effects on the phagocytic activity and total serum protein level. Chemical analysis showed that ForCo C was composed of glucose, galactose, xylose and arabinose. A close relationship between antitumor activities and polysaccharide contents waw observed. These results indicate strongly that antitumor active principle of Forsythia Corea is polysaccharide.

Water-soluble pectins isolated from Trichosanthes Rhizoma and Taraxii Herba and their deproteinized polysaccharides were purified through DEAE cellulose column and were applied to immunopotentiating and antitumor studies to clarify the nature of their activities of our previous reports. As the results of works, the lectins and deproteinized polysaccharides increased the number of circulating leukocytes and total peritoneal cells. And they markedly elevated the lowered production of antibody and reactivity of T Iymphocyte in tumor-bearing mice, which were rapidly recovered by discontinuance of sample treatments. They also decreased the growth of Sarcoma 180 solid tumor in mice.

Peritoneal dialysis (PD) is a clinical technique that therapeutically removes toxic solutes from body fluids and normalizes endogenous solutes whose aberrant concentrations disrupt normal physiology. This study retrospectively evaluated clinical outcomes and complications of PD in 20 dogs with renal failure. Blood works (total count of red blood cells (RBC), packed cell volume (PCV), the serum biochemical, and electrolyte values related to renal insufficiency) and complications associated with peritoneal dialysis, and clinical outcomes were recorded before and after PD. Additionally, creatinine reduction ratio (CRR) and urea nitrogen reduction ratio (URR) were calculated for evaluating the efficacy of PD. PD resulted in a significant (p < 0.05) reduction in blood urea nitrogen (BUN) concentration in 19 dogs, while a significant (p < 0.05) reduction in creatinine concentration in 17 dogs. The complications of PD were hypoalbuminemia (12/20, 60%), anemia (10/20, 50%), subcutaneous dialysate leakage (9/20, 45%), bacterial peritonitis (6/20, 30%), dialysate retention (5/20, 25%) and limb edema (4/20, 20%). This study demonstrated that PD was effective in reducing the magnitude of azotemia in dogs with renal failure especially in acute phase, although the complication rate was high but manageable.
