  • The effects of chemical compositions (protein, lipid, and dietary fiber) on the physical properties of dried biji powders were investigated. The raw biji was freeze-dried (control) and hot-air dried (untreated). The untreated biji was further defatted and deproteinated. The prepared biji powders were analyzed for the proximate composition, total dietary fiber (TDF), water absorption index (WAI), water solubility index (WSI), swelling power, solubility (including the quantification of soluble carbohydrate and protein fractions), and final viscosity (using a rapid visco analyzer). Control and untreated biji powders exhibited the similar chemical compositions. The defatted biji possessed higher TDF, although its protein content did not significantly differ for control and untreated ones. The deproteinated biji consisted mainly of TDF. WAI and swelling power increased in the order: deproteinated > defatted > control > untreated biji powders. WSI and solubility increased in the order: control > untreated > defatted > deproteinated biji powders. The similar patterns were observed for soluble carbohydrate and protein fractions. The deproteinated biji revealed the highest viscosity over applied temperatures, while the untreated one was lowest. Overall results suggested that the physical properties of the dried biji powder were reduced by protein and fat, but enhanced by dietary fiber.

  • The present paper focuses on the application of commercial acid dyes and wool reactive dyes to casein protein fabric. Nine acid dyes and six wool reactive dyes were compared their dyeing properties as well as color fastness. The exhaustion yields were higher than 80 % which dramatically increased at pH 3. Excellent wash fastness was obtained with metal-complex acid and wool reactive dyes. Both light and rubbing fastness were overall good, but perspiration fastness was comparatively poor.

  • Skin biopsy with investigation of small nerve fiber in human epidermis and dermis has been proven to be a useful method for demonstration of small fiber neuropathy. Quantification of intraepidermal nerve fiber density using anti-Protein Gene Product 9.5 (PGP 9.5) antibody is standardized method to diagnose the small fiber neuropathy. Skin biopsy method also makes it possible to differentiate the type of nerve fibers by using different antibodies. Quantification of dermal structures with different type of nerve fibers could be used to invest pathophysiologic mechanism of diseased state.

  • To evaluate the possibility of predicting a specific nutrient component, which nay be difficult in analysis, from a component of nutrient relatively easy to analyze, six grass roughage sources (bermuda grass hay, klein grass hay, oat hay, orchard grass straw, tall fescue straw and timothy hay) mainly used in Korea were analyzed for the heat-stable $\alpha-amylase$ treated neutral detergent fiber (aNDF), acid detergent fiber (ADF), acid detergent lignin (ADL), neutral detergent insoluble crude protein (NDICP) and acid detergent insoluble crude protein (ADICP) as well as proximate analytical components, and correlation coefficients between nutrient components were calculated. Some chemical components appeared to have significant correlation (p<0.05) through Pearson's correlation coefficients (i.e. between crude protein (CP) and NDICP in oat hay, orchard grass straw and tall fescue, between CP and ADICP in oat hay and timothy hay, between crude fiber (CF) and aNDF in klein grass hay, tall fescue straw and timothy hay, between CF and ADF in oat hay, tall fescue straw and timothy hay, and between CF and ADL in orchard pass straw and timothy hay). It is therefore suggested that it would be worthy to predict a specific nutrient component, which may be difficult in analysis such as aNDF, ADF, ADL, NDICP and ADICP, from a component of nutrient relatively easy to analyze such as CP and CF. However, it would be needed to improve the correlation coefficients, more samples should be measured.

  • Enzymatically hydrolyzed vegetable protein (eHVP) was produced from soy protein using proteases, and the physicochemical properties were examined. Soy protein hydrolysate of 6% protein and 50% degree of hydrolysis was useful for the base of savory ingredients. The Maillard-reacted and flavoring compound-added hydrolysate had improved flavor. It was for enzymatically hydrolyzed soy sauces and dehydrated seasonings. ISP hydrolysate of low molecular weight $(MW{\sim}250)$ and high protein content (85%) was suitable for special uses such as infant diets, sports nutrition, and medical diets. The eHVP gave no limitation of dosage in the formulation as a flavor enhancer. The byproduct of protein hydrolysis was found to have high content of fiber (21%) and to have potential for the use as dietary fiber or bulking agents.

  • The purpose of this study is to discuss and analyze the change of GLUT-4 and muscle fiber type of streptozotocin(STZ)-diabetic rats over a period of 6 weeks. We divided into four groups; I(aquatic exercise and feeding of Cordyceps militaris; n=6), test group II(feeding of Cordyceps miliaris; n=6), test group III(aquatic exercise; n=6), control group IV(non-treatment; n=6). After experimenting we measured the blood glucose, body weight, muscle fiber type and GLUT-4 protein content. The change of glucose levels decreased greater in group I than the other group. The body weight gain was lower in the all groups. The change femoris muscle fiber type, the size of muscle fiber TypeII lessened more than the one of Type I in group IV. Decrease of muscle fiber size more diminishment in group I than the other group. GLUT-4 protein quantity decrease in group IV compared to normal group. It was significantly increased in group. I, III compared to group IV. But there was more increase in group I (p<.001). These results suggest that GLUT-4 and muscle fiber type II decrease in STZ-diabetic rats and that when we apply aquatic exercise and feeding of Cordyceps militaris in diabetic rats over a period 6 weeks, it is increase GLUT-4 and the increase of insulin sensitivity of peripheral tissue. So it is considered to be helpful in improvement of glucose homeostasis and in prevent from muscle atrophy resulted from complication.

  • This study was conducted to investigate the effects of dietary fibers (cellulose ; polydextrose ; pectin ; ricebran) supplementation on the kidney fucntion of hyperlipidemic-induced rats on a high cholesterol diet (5% cholesterol). Serum lipid concentrations were not influenced by dietary fiber sources, but the pectin group was effective in reducing serum lipid levels. Total serum protein and albumin concentrations tended to higher in the polydextrose group, and serum creatinine and urea-N concentrations were higher in the pectin group than those in the other groups. Even though total urinary protein was high in the pectin group, GFR was reduced (18~30% decrease) as compared to other groups. The urea-N level was elevated in the polydextrose group as compared to that of cellulose group(25% increase). Total lipid, triglyceride and cholesterol concentrations in the liver of pectin group were lower than those of other groups. Total lipid and cholesterol concentrations in the kidneys were reduced in pectin and ricebran groups, respectively. The total cholesterol concentration infecal was significantly high in the polydextrose and pectin groups(p<0.05), and the triglyceride was highest in the pectin group. These results indicate no significant effects of dietary fiber supplementation on the kidney function of hyperlipidemic-induced rats on a high cholesterol diet, but pectin was very effective to improve lipid metabolism and to reduce GFR.

  • The Purpose of this study is to investigate the effect of soluble dietary fiber psyllium on insulin sensitivity and skeletal muscle glucose transporter 4(GLUT4) protein expression in stroke-prone hypertensive rats(SHRSP) fed a high-fat diet containing 5% of psyllium or cellulose from five to nine weeks of age. Obtained results were as follows : (1) In the psyllium diet group fasting plasma glucose level was significantly reduced and glucose levels upon oral glucose tolerance test were significantly lower than cellulose diet group at 30 min(p<0.05) and 60 min(p<0.01) (2) Skeletal muscle GLUT4 contents were significantly increased in the soleus(slow twitch) and extensor digitorum longus(fast twitch) muscle of psyllium diet group. (3) However there was no difference in insulin levels in the fasting and oral glucose tolerance test. These results indicated that psyllium diet improves peripheral insulin sensitivity but not insulin secretion. In conclusion our present finding suggest that soluble fiber diet is effective to increase insulin sensitivity in SHRSP. From these results it was suggested that soluble dietary fiber supplementation effectively prevents insulin resistance.

  • Mongolian cashmere sliver, yarn, and fabric were dyed and bleached with a solution of ascorbic acid and iron sulfate at $70^{\circ}C$, and then dyed using natural indigo powder at the dyeing temperature of $25^{\circ}C$ to $90^{\circ}C$ for 15-90 minutes using the IR dyeing machine. K/S values of bleached samples decreased significantly when dyed above $70^{\circ}C$ dyeing temperature for a longer dyeing time. Bleached cashmere fabric showed a greater loss of tensile strength than unbleached cashmere fabric, even when the samples were dyed at $40^{\circ}C$. With a higher dyeing temperature, yarns lost fullness, became thinner, and the pores between the yarns were enlarged. The x-ray diffraction pattern exhibited a prominent increase in crystallinity and the protein assay indicated a loss of protein in the bleached sample dyed at $90^{\circ}C$. Thinning of scales, fractured or raised tip of scales, and roughness on the entire surface of the fiber were also observed. The results indicate that bleaching and high temperature dyeing cause a serious damage to cashmere fibers. In addition, bleaching and high temperature dyeing cause significant fiber damage. Natural indigo dyeing using low temperature dyeing is recommended to produce blue color cashmere.
