This study investigated the nutritional characteristics of before and after fermentation of domestic soybean (Glycine max L.) by Rhizopus oligosporus. The soybean storage proteins, β-conglycinin (11S globulin) and glycinin (7S globulin), were the most abundant in Seonyu (SY) and Danbaegkong (DBK), with concentrations of 253.4 mg/g and 193.0 mg/g, respectively. For 11S/7S related to sulfur-containing amino acid, DBK had a value of 0.95, making it the most excellent nutritionally among all the cultivars. The free amino acid content significantly increased from 0.04~10.45 mg/g before fermentation to 1.37~16.95 mg/g after fermentation, and the essential amino acid composition increased, confirming an improvement in protein quality after fermentation. Phytic acid, known as a nutritional inhibitor of soybeans, decreased from 1.66~2.13 g/100 g before fermentation to 0.90~1.58 g/100 g after fermentation, suggesting that mineral absorption inhibition was alleviated. In addition, the trypsin inhibitor content is suppressed by 76.20% to 81.25% after fermentation, which is expected to improve protein utilization in the body. This study confirmed some properties of fermented products by Rhizopus oligosporus using domestic soybeans, and these results are presented to serve as the basic data for establishing new uses of Korean soybean cultivars.

This research was for investigating the physiological effect caused by genetic disorder and others. Serum protein, serum LDH, and serum CPK were analyzed on Fragile X syndrome patients, carriers, unclassified mental retardees, and Down's syndrome patients by cellulose acetate plate electrophoresis. Also enzyme activity of LDH and CPK were measured. Significant differences were observed between normal group and mental retardees in compositions of serum protein, serum LDH, serum CPK, and enzyme activities. Mean percentages of albumin were 53.70$\pm$7.73% for Fragile X syndrome patients, 57.09$\pm$7.73% for carriers, 47.33$\pm$6.06% for unclassified mental retardees, 50.19$\pm$ 15.72% for Down's syndrome patients. Mean percentages of ${\gamma}$-globulin were 19.64$\pm$6.71% for Fragile X syndrome patients, 19.24$\pm$3.38% for carries, 25.66$\pm$4.74 for unclassified mental retardees, 23.41$\pm$6.08% for Down's syndrome patients. Mean percentages of LDH3 were 27.76$\pm$2.72% for Fragile X syndrome patients, 22.70$\pm$2.76% for carriers, 25.42$\pm$1.26% for unclassified mental retardees, 27.72$\pm$2.58% for Down's syndrome patients. Mean percentages of LDH4 were 2.70$\pm$2.04 for Fragile X syndrome patients, 3.79$\pm$2.74% for carriers, so both of them were significantly lower than normal(P<0.05). Mean percentages of CK-MB were 3.96$\pm$5.56% for Fragile X syndrome patients, 8.80$\pm$7.92%. Mean percentages of CK-MM were 95.81$\pm$5.50% for Fragile X syndrome patients, 91.20$\pm$7.92% for carriers. These results showed that significant abnormal compositions of blood proteins might be caused by genetic disorder. However, further analysis of many patients will be needed for clear conclusion.

Soybean grain is most widely used and soybean crop produces most high protein per area among crops. To meet rapid increase of human population and supply protein in safety. soybean has considered more and more important crop. And it has been emphasizing that high quality and high protein soybean breeding must be made efforts in future. Many papers related to soybean breeding for high quality and protein and soybean protein composition have suggested the problems to do in future. Soybean germplasm collection. classification and conservation should be continuously performed, and it is emphasized that wild type of soybeans (G. soja) be considered to use in breeding for high protein varieties. Selections would be better emphasized in first yield and therefore high yield of protein per area. Selection for high protein would be secondary criterion. High protein lines with high yielding potential could be selection from certain populations, and breeders should consider this phenomenon in procedure of selection. Heritability of protein percent is relatively high and genetic gain of increment of protein percent is large. Soybean protein which is comprised 70 to 90% of globulin is constituted mostly 11S and 7S proteins. Sulfur-containing amino acids, methionine and cysteine, are identified to contain more in 11S protein than 7S protein. High 11S germplasm should be desirable to use in crossing plan, and selection of high ratio of 11S/7S lines be better in development of high quality varieties.

It has been suggested that dietary fat increases the risk of breast cancer by elevating serum estrogen concentrations. However, studies on a relationship between fat intake and breast cancer risk have shown contradictory results, possibly because the levels of fat intake in study populations were too high to observe differences. Also, the effect of other dietary factors may present. The present study was performed to investigate the relationship between diet and estrogen metabolism in premenopausal women whose usual fat intake is relatively low compared to their western counterparts. Twenty lacto-ovo vegetarians (LOV) and twenty omnivores participated in the study. Three day food records including a Saturday or a Sunday were used to estimate nutrient intake. Serum lipids, estradiol, sex-hormone binding globulin, and urinary estradiol were measured. Study results showed $24.8\%$ and $20.9\%$ of energy intake were provided from fat in omnivorous and LOV subjects, respectively. Serum and urinary levels of estradiol were two times higher in omnivores. Fat intake was not related to either serum estradiol nor urinary estradiol when the Spearman correlation coefficient analysis was performed. Carbohydrate, total dietary fiber and soluble dietary fiber intakes were negatively related to serum estradiol concentration. Legumes, vegetables and fruit consumption showed significantly negative relationships with both serum and urinary estradiol concentrations. These results indicate lower estrogen availability may be associated with plant food­based diets in premenopausal women whose usual diets contain less than $25\%$ of energy as fat.

Objectives : To investigate effects of Achyranthis Radix aqua-acupuncture on adjuvant arthritis in rats. Methods : After eliciting arthritis in Sprague dawley(SD) rats by injection of Freund's complete adjuvant for 2 weeks, normal saline was injected for the Exp. I group and Achyranthis Radix aqua-acupuncture was injected for the Exp. II group during 30days. The selected point was Dokbi (ST35) in both groups. Then the edema rate, the number of WBC, the quantity of total protein, albumin and globuline in the blood serum, and histological test of the muscular tissue were measured in the arthritis stricken areas. Results : I) The volume of the paws were checked. The volume of the paws was $0.84{\pm}0.l4mm$ in the Exp. I group and $0.47{\pm}0.14mm$ in the Exp. IIgroup. The swelling of the paws was restricted significantly in the Exp. II group(P<0.05). 2) The number of WBC was $10.34{\pm}0.14(l03/ml)$ in the normal group and $37.47{\pm}5.46(103/ml)$ in the Exp. I group. It was $21.24{\pm}2.58(103/ml)$ in the Exp. II group. This fact showed that treatment with Achyranthis Radix aqua-acupuncture adminstered to the Exp. II group was more effective than the Exp. I group in the treatment of arthritis(P<0.05). 3) The content of the total protein in the blood serum was $6.14{\pm}43g/dl$ in the normal group, $7.95{\pm}0.94g/dl$ in the Exp. I group, and $6.41{\pm}0.68g/dl$ in the Exp. II group. There was no significance in total protein between the Exp. II group and the Exp. I group from the statistical analysis. 4) The content of albumin in the blood serum was $2.94{\pm}0.l3g/dl$ in the normal group, $2.01{\pm}0.48g/dl$ in the Exp. I group and $3.15{\pm}0.27g/dl$ in the Exp. II group, which revealed a significant increase in the serum albumin from the statistical analysis of the Exp. II group compared with the Exp. I group. 5) The content of the globulin in the blood serum was $3.19{\pm}$0.48g/dl in the normal group, $4.70{\pm}1.26g/dl$ in the Exp. I group and $3.26{\pm}0.57g/dl$ in the Exp. II group. There was no significance in the serum globulin between the Exp. II group and Exp. I group from the statistical analysis. 6) In histological findings, because of severe inflammatory reaction, remarkably irregular tissue and large amount of inflammatory cells were found in the Exp. I group. But the Exp. II group showed a small amount of inflammatory cells, the refrained inflammatory state and even recovering state. Conclusions : These results show that Achyranthis Radix aqua-acupuncture reduces the inflammatory reaction and muscular tissue necrosis in SD rat's paws induced by Freund's complete adjuvant.

In an attempt to evaluate the diagnostic significance of the serum thyroxine binding globulin (TBG) in various thyroid disease states, the authors measured serum $T_3$ uptake, $T_3$, total $T_4\;free\;T_4$, TSH and TBG by radioimmunoassay technique, and calculated the free $T_4$ index$(FT_4I)$ and $T_4/TBG$ ratio in 10 cases of normal subjects, 11 cases of hypothyroidism, 62 cases of euthyroidism and 37 cases of hyperthyroidism. The data were analysed in the aspects of diagnostic significance in each thyroid disease state, and the results were as follows; 1. In 10 cases of normal subjects, serum TBG was $17.4\sim26.8{\mu}g/ml$, $FT_4I$ was $5.1\sim9.7$, and $T_4/TBG$ ratio was $21.9\sim49.9(Mean{\pm}S.D.)$. 2. In 62 cases of euthyroidism with diffuse and nodular goiter, $FT_4I$ was $7.26{\pm}1.82,\;T_4/TBG$ ratio was $31.47{\pm}10.42$, and there were no significant difference from those of normal subjects (p>0.5). 3. In 11 cases of hypothyroidism, the $FT_4I$ was $3.13{\pm}2.15,\;T_4/TBG$ ratio was $11.3{\pm}5.31$, significantly lower than normal controls (p<0.01). 4. In 37 cases of hyperthyroidism, the $FT_4I$ was $30.0{\pm}12.0,\;T_4/TBG$ ratio was $121.4{\pm}62.2$, significantly higher than normal controls (p<0.01). 5. There were significant correlations between the $FT_4I$ and $T_4/TBG$ ratio, total $T_4\;and\;T_4/TBG$ ratio, in each thyroid function states. 6. The $FT_4I$ showed 100% of diagnostic value in hyperthyroidism, 89.2% in euthyroidism, and 80% in hypothyroidism group. The $T_4/TBG$ ratio showed 100% of diagnostic value in hyperthyroidism and hypothyroidism, and 80.6% in euthyroidism group. The above results suggest that $T_4/TBG$ ratio and $FT_4I$ showed same diagnostic value in hyperthyroidism group, but $T_4/TBG$ showed higher diagnostic significance than $FT_4I$ in hypothyroidism.

Liver functions in diffuse parenchymal liver disease such as cirrhosis of the liver depend largely on the effective hepatic blood flow rather than on the individual cell functions. Clinical methods of measuring the hepatic blood flow were developed recently by the application of colloidal disappearance rate. In order to correlate the radiogold disappearance rate to conventional biochemical liver function tests, 21 normal subjects and 80 cases of cirrhosis of the liver were studied with both methods. The results are summarized as following: 1. The validity of external counting method to measure the blood disappearance rate of colloidal radiogold was confirmed by in vitro counting of the serial blood samples. 2. The blood disappearance rate of collidal radiogold was essentially the same. as the liver uptake rate of colloidal radiogold in normal and cirrhotic subjects with various degrees of functional disturbance. And it seemed there was no serious extrahepatic removal of the colloidal radiogold. 3. The disappearance rate of colloidal radiogold was not significantly changed by the posture change, but was enhanced by ingestion of 500 ml of water. 4. The disappearance rate of colloidal radiogold was not influenced by single dose of Telepaque, while BSP retention was increased after Telepaque. 5. The mean disappearance half time of colloidal radiogold in normal subjects was $2.49{\pm}0.391$(S.D.) minutes. The mean normal disappearance rate constant (K value) was $0.285{\pm}0.0428$(S.D.)/minute. 6. The colloidal radiogold disappearance half time was abnormally prolonged (over 3.2 min.) in $87.7{\pm}3.68$(S.D.) % of cirrhotic subjects. 7. In patients of liver cirrhosis the blood disappearance rate of colloidal radiogold correlated well to serum albumin and globulin levels and BSP retention which were considered to reflect functions of hepatic parenchymal cells. There was, however, no correlation between colloidal disappearance rate and thymol turbidity test, serum glutamic pyruvic transaminase, and serm alkaline phosphatase activities. The latters were considered to be associated with the activity of liver disease.
