To find antitumor components from the higher fungi of Korea, the mycelia of Favolus alveolarius (Fr.) Quelet were cultured in a liquid medium. The cultured mycelia were extracted with hot water twice, and a high molecular weight fraction was obtained by adding two volumes of ethanol to the extract. Two grams of Fraction A were obtained by dialyzing it. It was further separated into four fractions by gel filtration with Sepharose CL-4B, and they were designated Fractions B, C, D, and E. The results of the antitumor test showed that Fractions A, B, C, D and E had tumor inhibition ratios of 92.3, 78.5, 59.6, 77.4 and 62.2%, respectively. Anthrone test was carried out to determine the contents of total polysaccharide of the five fractions, and they had 46.3, 27.3, 65.3, 64.6, and 46.1%, respectively. The contents of the total protein of the five fractions were 29.4, 13.9, 14.3, 14.3, and 29.1%, respectively. Monosaccharide subunits of each fraction were analyzed with gas chromatography, and glucose, xylose, mannose, galactose and fucose were identified. Fraction A was examined for immunological effects. It increased the count of hemolytic plaque forming cells 12.8 times to that of the control group, and the population of macrophage in peritoneal cavity 3.2 times to that of the control group.

An in vitro immune effector mechanism against the target encysted metacercariae of Paragonimus westermani was demonstrated in the rat system. Peritoneal exudate cells, mainly macrophages from normal rats, showed adherence to and killing of encysted metacercariae of p. westermani in the presence of complement-independent serum from rats infected with Paragonimus metacercariae. These reactions were specific for the excysted metacercariae, as tissue-migrating juvenile worms were not affected. Damage of encysted metacercariae of p. westermani due to antibody and macrophages was assessed by morphological observation, by cell adherence reaction and by the use of vital dyes. frypan blue dye exclusion proved to be a reliable indicator of judging metacercarial viability. Electron microscopic studies demonstrated that macrophages reacted with fusty material on the tegumental surface and fine structures in the syncytium of the parasites. The tubular tunnels formed between the basement membrane and muscle layers of the damaged parasites were also noticeable. The relevance of these findings to cellular immunity in the early paragonimiasis was discussed.

Essential oil-excluded Artemisia princeps Pamp var Ssajuarissuk (AP) was fermented with Lactobacillus brevis K-1, which was isolated from cabbage Kimchi, and the anti-inflammatory effects of AP and fermented AP (FAP) on lipopolysaccharide (LPS)-induced inflammatory response in peritoneal macrophages were investigated. AP and FAP inhibited LPS-induced TNF-$\alpha$, IL-$1{\beta}$, COX-2, iNOS and COX-2 expression, as well as NF-${\kappa}B$ activation. AP and FAP also reduced ear thickness, inflammatory cytokine (TNF-$\alpha$, IL-$1{\beta}$ and IL-6) expression and NF-${\kappa}B$ activation with 12-O-tetradecanoylphorbol-13-acetate (TPA) induced dermatitis in mice. Furthermore, AP and FAP also reduced exudate volume, cell number, protein amount, inflammatory cytokines (TNF-$\alpha$, IL-$1{\beta}$ and IL-6) expression and NF-${\kappa}B$ activation in carrageenan-induced air pouch inflammation in mice. The inhibitory effects of FAP were more potent than those of non-fermented AP. Based on these findings, we propose that FAP can improve inflammatory diseases, such as dermatitis, by inhibiting the NF-${\kappa}B$ pathway.

Immunopotentiating activity of water extract of Lycii Fructus, Rubus Fructus, Torilis Fructus, Schizandrae Fructus and Cuscutae Semen were investigated using mouse fed with normal diet and protein deficient diet. Body weight, ratio of spleen or thymus to body weight, number of total peritoneal exudate cell, content of total serum protein and albumin content were decreased in the mouse fed with protein deficient diets as compared to the mouse fed with normal diet. Regardless of the nutritional condition, the supplement of the water extract of Lycii, Rubus Torilis, Schizandrae Fructus or Cuscutae Semen increased the ratio of spleen to body weight. The increment of this ratio was significant by the supplement of water extracts of Lycii and Torilis Fructus in mouse fed with protein deficient diet. The supplement of water extracts of Torilis Fructus to the mouse fed with protein deficient diet increased the content of total serum protein and albumin content significantly. Similar results were obtained with Lycii, Rubus, Schizandrae Fructus and Cuscutae Similar. The electrophorogram shows the difference in the concentration of some serum protein constituents between the mouse fed with normal diet and protein deficient diet.

In order to research for compound of immunomodulatic and anti-allergic function. These experiments were conducted to investigated the effects of hot water extracts(PRWE) , ethanol extracts (PREE) and polysaccharide fraction extracts (PRPE) extracted from platycodi radix on immune response. The effect of these platycodi radix extracts on hemagglutinin titer(HA), hemalysin titer(HY), plaque forming cell(PFC), rosette forming cell (RFC) and phagocytosis was Investigated by using BALB / C mice. The results obtained from this study are as follows. Generally, the oral administration of extracts fractions for 10 days each other resulted in the enhanced HA and HY. In the experiment of PFC and RFC, the results of experimental groups which was given each samples compared to control group showed the enhanced level of activity such as PRPE 160% and 196% each other But PRWE and PREE decreased or wear not changed. When PREE, PRPE or PRWE was given to mice orally, PREE and PRPE significantly enhanced the phagocytic activity of peritoneal exudate cells(PEC), spleen cells(SC) and monolymphocytus cell(MC), about from 150% to 250%, but PRW was decreased.

Protein-polysaccharide fractions, PJ-3 and PJ-4, were prepared from mycelial culture filtrate of an insect-born fungus, Paecilomyces japonica DGUM 32001, and subjected to a flow cytometrical analysis for their vivo antitumor and immunomodulating activity in ICR mice. When i.p. injected once daily for semen days at 100 mg/kg, PJ-4 exerted a strong antitumor activity showing the growth inhibition ratio of 85.1% against i.p. implanted sarcoma 180 cells, while PJ-3 showed only a weak activity. Moreover, PJ-4 signiscantly increased the expression level of CD25 (IL-2R $\alpha$-chain) as well as forward scatter (FSC) values of splenic CD8$^{8}$ T cells. It is also noteworthy that PJ-4 strongly induced the peritoneal exudate cells in the same experiment. In an in vitro study, PJ-4 slightly inhibited the growth of sarcoma 180 cells at the concentration of 50$\mu$g/ml or higher. These results strongly suggest that PJ-4 might exert its antitumor activity through immunostimulation as well as direct inhibitory activity on the tumor cells.

The immunomodulating effects of polysaccharide extracted from Ganoderma lucidum(PSG) on macrophage were evaluated using murine macrophage cell line ATCC TIB 71 cells or peritoneal exudate cells of BALB/c mice. The cell were incubated with various content of PSG for 24 hours at 0.5% $CO_2$ incubator under varying experimental conditions. PSG stimulated the non-specific activites of macrophage such as mitotic activity and expression of surface interleukin-2 receptors by dose-dependent pattern with statistic significance(p<0.001): however, PSG had little immunoregulatory effects on cytokines derived from peritoneal macrophages of BALB/c mice. There were no significant changes in the se-cretion of interleukin-6, interleukin-6, or tumor necrosis factors(Tn) of PSG treated cells compared to the control group. But PSG increased secretion of cytokines(IL-1 and TNF) when the cells were primed and trigged with BCG and IFN-${\gamma}$.

The polysaccharide fractions were isolated and purified from Phellodendron chinese SCHNEID, and antitumor activities using the melanoma B-16-derived metastatic tumors were examined at dosages of 2, 5 and 10 mg/100 g. F-7 and F-8 showed the highest tumor metastatic inhibitory activities (inhibition ratio 60 and 80% in 2 mg/100 g), and in dose of 5 mg/100 g, the inhibitory ratios were 85 and 70%, respectively. Furthermore, 10 mg/100 g of intraperitoneal (i.p.) injection gave 90 and 95% of inhibition. When the effects of polysaccharides on hypersensitivity were examined, the inhibitory activities were not markedly observed in oral administration, indicating that the polysaccharides are directly acting to immune system. Also, the polysaccharides increased the number of circulating blood leukocytes and total peritoneal exudate cells. Although implantation of tumor cells greatly decreased the productivity of antibody (antibody-mediated) and T lymphocyte reactivity (delayed-type) as 6.3 from 9.3 and 5.9 from 7.7, represented by the increase of footpad thickness, respectively. the polysaccharides elevated the reactivity of T lymphocyte in tumor-bearing mice, which were rapidly recovered by discontinuance of sample treatments. Especially, F-2, F-5, F-7 and F-8 remarkably recovered the decreased sensitivity. These results clearly indicated that the i.p. injection is much effective to suppress tumor growth than oral administration.
