  • To study e(feces of Korean Binseng (Parfax ginseff C. A. hfeyer) total saponin fraction on spermidine and spermine metabolism in rat reproductive systems, we administrated the saponin fractation to rats for 2 years. Then, we determined the activities of S-adenosylmethionine decarboxylase (SAMDC), the quantitation of the enzyme protein and the amounts of spermidine and spermine contents In prostate and testis. In young sexually immature stage, administration of Korean ginseng saponin fraction showed no effect on SAMDC activities. The stimulatory effect on the activities of SAMDC gradually increased and reached maximal activities in test groups of prostate and testis at sexually mature stage. The amounts of SAMDC protein in test groups were paralleled by the changes of SAMDC activities in test groups, indicating that all of the increased activity occurring in administration of ginseng saponin fraction was not due to the activation of SAMDC activity but to the Increase in enzyme protein. However, the spermidine and spermine contents of test groups showed small increase in compared to that of control groups. From these results, we suggest that administration of ginseng saponin fraction alter the spermidine and spermine metabolism in sexually mature and aged reproductive systems in rats.

  • The amount of norepinephrine and dopamine in the brain of the mouse fed with normal diet or protein deficient diet with supplement of the saponin fraction of ginseng were determined by the sluorometric method. THe amount of norepinephrine in mouse brain was vivider in the case of protein deficiency. The increase amount of dopamine was observed only in the case of mouse fed with normal diet with supplement of the saponin fraction normal diet with supplement of the saponin fraction of ginseng for 8 weeks.

  • A protein-polysaccharide fraction was prepared from the carpophores of Laetiporus sulphureus. This fraction suppressed growth of sarcoma 180 in A-strain mice when administered i. p. To investigate the mechanism of antitumor action of this fraction, plaque assay was conducted by administrating i. p. to the mise at a dose level of 50mg/kg for five days. Ten days later, the mice were immunized with 1 * 10$^{7}$ sheep red blooc cells. The number of hemolytic plaque forming cells was significantly greater than that of the control mice. Three monosaccharides and fifteen amino acids were identified in the protein-polysaccharide fraction.

  • The total serum protein, protein fractions by paper electrophoresis and A/G ratio in pregnant rabbits were observed. The results obtained in this work were sumrnerized as follows: 1. Total serum protein and the fraction of serum albumin revealed a decrease with the advancing of gestation, especially total serum protein was decreased significantly on 3 weeks of pregnancy. There was a tendency to return tward control level on one week after delivery. 2. The fraction of ${\alpha}_1$, and ${\alpha}_2$-globulin showed little changes during the period of gestation. 3. The fraction of ${\beta}$-globulin was increased more or less during the period of gestation, and on one week after delivery showed considerable increase but the increase was statistically insignificant. 4. The fraction of ${\gamma}$-globulin revealed a variable changes during pregnancy but there was no significant differences. 5. A/G ratio was significantly decreased at 3 weeks of pregnancy and the ratio was near control level on one week after delivery.

  • 여러가지 육가공품(肉加工品)중 특정 단백질 원료의 첨가여부를 판정하여 변조식품(變造食品)을 검출하는 한 방법으로서, 각종 육류단백질, non-meat protein, 어육(魚肉)가공품을 대상으로 disc SDS-Poly acrylamide gel electrophoresis의 사용 가능성을 실험하였다. Total protein fraction에 대한 전기영동 결과 복잡하고 많은 band를 보여 각 시료에 고유한 특성을 찾아보기 어려웠다. Low salt-soluble protein fraction에서는 total protein fraction 에서 보다 band 수가 상당히 감소함을 보였고 각 단백질 원료에 대하여 보다 고유한 band pattern을 나타내었다. Acetone-insoluble protein fraction 에서는 non-meat protein의 경우 육류단백질과 상당히 다른 경향을 나타내었고. 소세지 원료의 가열처리에 의하여 단백질의 band수와 양이 감소하였다. 따라서 적당한 단백질 추출조건(抽出條件)을 설정하여 전기영동을 실시하면, 특정(特定) 단백질을 첨가한 변조식품의 검출이 가능해질 것으로 생각된다.

  • In the previous report, we described the marked antitumor and immunomodulatory activities of PVp, a protein-polysaccharide fraction of a Korean wild mushroom Psathyrella velutina. In this study, a protein-polysaccharide fraction, PVMP, was prepared from the shake-cultured mycelia of the same mushroom and its immunoactivities as well as chemical compositions were investigated. At 200 $\mu\textrm{g}$/ml, PVMP weakly stimulated the BALB/c mouse splenic lymphocytes to form lymphoblasts and upregulated the expression of CD25 molecules, but failed to stimulate peritoneal macrophages. In chemical analysis these two protein-polysaccharide fractions were found to be quite different in that the carbohydrate contents of PVMP and PVP, respectively, was 85.3% and 41.2%. These results reveals that PVMP, unlike PVP, is a moderate immunostimulator on the immune system.

  • To investigate the svnthyesis of muscle proteins during differentiation of chicken myoblast, cvtosolic and membrane fractions were used for both sodium dodecvl sulfate polvcrylamide gel eBectrophoresis and two-dimensional gel electrophoresis. An extensive cell fusion was observed in 4 day culture. In the protein pattern of the cvtosolic fraction from SDS-PAGE. several protein bands including 250 kDa and 46 kDa showed remarkable changes during culture. the protein of 46 kDa was the most prominent one ann its optical density was the highest in 5 day culture (OD = 1.30). In the membrane fraction, band of 19.8 kDa showed the highest absorbance with 0.93 OD at 12 hr after initial plating and decreased gradually thereafter to 0.23 in 5 nay culture. From the results of two-dimensional gel electrophoresis of cytosolic fraction, the 46 kDa spot was observed as ko separated forms from culture 2 nary culture, and the sixte of this spot was the largest in 5 nay culture. In the pattern of membrane protein, the extensive appearance of newiv synthesized Proteins was found in a naut culture, but no Prominent spot was observed throughout culture. From the results of the present clay, we found that, during myoblast differentiation, the most prominent proteins were bands of 46 kDa and 19.8 kDa in cvtosolic and membrane fraction, respectively, and the appearance of new proteins was initiated at 48 hr after initial plating, and the 46 kDa protein was predominant in the cytoplasm of late culture in which extensive cell fusion was observed.

  • The dried carpophores of Sarcodon aspratus were examined for mineral elements and a protein-polysacccharide. Calcium, iron, zinc, magnesium, manganese, copper, lead, cadmium and mercury were detected in that order of contents by atomic absorption spectrometry and automatic mercury analysis. The protein-polysaccharide fraction extracted from the carpophore was found to contain 31.5% protein and 52.8% polysaccharide. The fraction showed no antitumor activity against sarcoma 180 implanted in mice.

  • To determine in vitro effects of phenylbutazone and niflumic acid on warfarin binding to rabbit serum protein, warfarin was added to the rabbit plasma, and the bound fraction was determined by warfarin-protein complex fluorescence. The bound fraction was decreased by phenylbtazone and niflumic acid. From this effect niflumic acid was found to have the more potent ability to displace warfarin from protein binding sites than phenylbutazone.

  • When at liver homogenates were incubated with 1mM $CCl_4$ for five min, glycogen level was decreased, while treatment with protein fraction $G_4$ increased the glycogen level. In addition $G_4$ inhibited the phosphorylation of 34 KD and 118 KD polypeptides induced by $CCl_4$. These protein were more strongly phosphorylated by $Ca^{2+}$/calmodulin-dependent kinase than by C-kinase. Since 34 KD polypeptide was solely phosphorylated by NaF (50mM), an inhibitor of both glycogen syntheses and phosphoprotein phosphates, it is inferred that 3 KD polypeptide is glycogen synthase-likd protein. Because glycogen synthesis is inhibited by phosphorylation of $Ca^{2+}$-dependent glycogen syntheses, it is suggested that $G_4$ increased liver glycogen level by inhibiting phosphorylation of 34 KD polypeptide which is thought to glycogen syntheses-like protein.
