  • Antitumor and immunoadjuvant activities of Bifidobacterium adolesentis ATCC-15703 were investigated against the ascites and solid forms of tumor induced by Sarcoma 180(S-180) in ICR mice. When 100 $\mu$g of the bacterium was intraperitonealy administered in the mice, the survival rate(T/C %) of the mice was 132% for 50 days after the inoculation of S-180, however the increment of their body weights was suppressed. When the 100 $\mu$g was subcutaneously adminis- tratered at the right grion, the suppresion rate of the tumor growth on the 21st day after inoculation of S-180 were 62.3%. Complete supression of the tumor growth was observed from 2 out of 8 test mice. The bacterium itself appeared to have noncytotoxic substance against the S-180 in vitro. The bacteria] administration markedly enhanced the activity of peritoneal macrophages. The num- ber of peritoneal macrophages at one day after the administration of the 100 $\mu$g increased about 8 times as much as that of the control, and the highest activity of acid phosphatase appeared at 2 days.

  • 3-Arylisoquinolin-1(2H)-ones (2) are possible bioisosteres of the $5-[4^{l}-(piperidinomethyl)phenyl]-2<$,3-dihydroimidazo[2,1-$\alpha$]isoquinoline (1) which is in clinical evaluation for the treatment of cancer. Structure-activity relationship studies of 3-arylisoquinolin-1(2H)-ones. (2) led to the synthesis of 3-arylquinolin-2(1H)-ones (3). A number of 3-phenyl substituted quinolin-2(1H)-ones were synthesized and tested for their in vitro antitumor activity against four different human tumor cell lines and 3-phenyl-N-benzyl-3,4-dihydroquinolin-2(1H)-one (12) showed the most potent activity.

  • The purpose of the study was to verify if or not as funtional food by estimating antitumor activity and antimicrobial activity of Coriolus versicolor(Fr.)Quel and Ganoderma Lucidum (Fr.)Karst. 1. The contents of moisture. crude fiber and crude protein of GL were higher $(18.28\%,\;10.3\%,\;78.4\%)$ than that of CV, but the content of crude lipid GL was higher than that of CV. 2. Inhibitory effects of on the growth of AGS human gastric adenocarcinoma cells and HT-29 human colon adenocarcinoma cell were increased by increasing of concentration in added methanol extracts of CV and GL. 3. Antimicrobial activity on Escherichia col1; Staphylococcus aureus, Salmonella typhimurium existed methanol extracts of CV. Therefore. it is suggested that CV is worth as functional food.

  • Some components and antitumor effect of antler and fermented antler with Bacillus P-92 were determined. By fermenting the antler with Bacillus P-92, the amount of free amino acids, polypeptides and other compounds were increased. The free amino acid of the fermented antler was 6-fold higher than those of the untreated antler. Sarcoma 180 cells were intraperitoneally implanted into ICR mice to determine the effect of fermented antler and untreated antler on life span prolongation. The life span of ICR mouse treated with antler and fermented antler were prolonged to 24.4% and 39.2%(p<0.05), and survival rates were 22% and 33%, respectively. In addition, the induction of neutrophil was 2.3-fold and 3.4-fold, respectively.
