We analyzed the concentration of Aspartate Aminotransferase (AST), Alanine Aminotransferase (ALT), Alkaline Phosphatase (ALP), Gamma Glutamyl Transferase (GGT), total protein (TP), albumin, total cholesterol (TC) and triglyceride in sera of patients (n=455) aged 60 years and older with hyperglycemia (${\geq}120mg/dL$ in serum). The average concentration of biochemicals in patient group was compared with those in reference group. Our data showed that the average concentrations of AST and TC in sera of senior patients with hyperglycemia were significantly increased by 27.5% (P<0.05) and 82% (P<0.05) in total group, 38.5% (P<0.05) and 75.0% (P<0.05) in sixty years' group, 16.0% (P<0.05) and 89.7% (P<0.05) in seventy years' group and 27.0% (P<0.05) and 79.5% (P<0.05) in eighty years' group, respectively. Patients with hyperglycemia showed a significant decrease in albumin level by 6.7% (total group, P<0.05), 4.5% (sixty years' group, P<0.05), 8.9% (seventy years' group, P<0.05) and 4.5% (eighty years' group, P<0.05), respectively. In conclusion, the high concentration of glucose in the senior patients with hyperglycemia may be a cause of severe liver function and lipid metabolism disorder.

A total of 120 male and 240 female quail (Coturnix coturnix Pharaoh) were used to determine the effect of feeding time on laying and reproductive performance of Pharaoh quail. They were fed ad libitum between 09:00 to 17:00 or full day, daily. Each female-male pair was housed in multiple-bird cages and colony cages. Initial and final body weight, quail-day egg production, feed consumption per egg and mortality were measured to determine laying performance of breeders. A total of 960 eggs were used to determine reproductive performance of quail in each treatment group. Eggs were incubated in a commercial setter and hatcher in standard conditions. Embryonic mortality, apparent fertility, hatchability of total and fertile eggs were calculated to determine the reproductive performance. Results indicated that feeding between 09:00 to 17:00 h reduced final body weight and egg production (p<0.001, p<0.001). Whereas, limited time of feeding improved hatchability of total (p<0.001) and fertile eggs (p<0.001) and reduced embryonic mortality (p<0.001) when compared with the effects of feeding full day. It was found that there were no significant differences for the egg production of quail housed in different cage systems. Quail caged in multiple-bird cages consumed less feed (p<0.01) compared to quail housed in colony cages. There were significant differences for the mortality (p<0.05), hatchability of total (p<0.001) and fertile eggs (p<0.001), and embryonic mortality (p<0.001) during the incubation due to main effect of cage systems. There were significant cage $systems{\times}feeding$ time interactions for hatchability of total and fertile eggs and embryonic mortality (p<0.001). As a conclusion; feeding from 09:00 to 17:00 reduced laying performance of quail and improved the reproductive traits compared to full day feeding of quail breeders. But, further investigations are needed to determine the optimum length of feeding time and egg production of breeders in quail fed limited time must be evaluated in comparison with its beneficial or detrimental effects.

Objectives : To investigate the fetal cholesterol levels and related factors in a rural adult population. Methods : 3,207 adults(1,272 men and 1,935 women) were examined in 1997 Their heights, weights, and fasting serum total cholesterol levels were measured, and their body mass indices were calculated. A questionnaire interviewing method was used to collect risk factor data. Results : The mean value of total cholesterol were 190.5 mg/dl, and 198.8 mg/dl, and the age-adjusted prevalence rates for hypercholesterolemia (above 240 mg/dl) were 13.7% and 10.2%, in men and women, respectively. From simple analyses, age, educational level, coffee intake, amount of meat and food intake, waist circumference, waist-hip circumference ratio(WHR), and body mass index(BMI) were significant risk factors in men (p<0.05) relating to serum total cholesterol levels. In women, age, educational level, hypertension history, diabetes history, herbal drug history, amount of feed intake, alcohol consumption, waist circumference, WHR, BMI, and menopausal status were significant risk factors (p<0.05). In multiple linear regression analyses, waist circumference (p<0.01), BMI (p<0.01), and coffee intake (p<0.05) proved to be significant risk factors in men. Whereas, menopausal status (p<0.01), BMI (p<0.01), herbal drug history (p<0.01), amount of food intake (p<0.05), waist circumference (p<0.05), and alcohol consumption (p<0.05) were significant risk factors in women. Conclusions : The significant risk factors, for both men and women, relating to the serum total cholesterol were waist circumference and BMI. Thus, for the reduction of serum total cholesterol level, it is recommended that health education for the control of obesity should be implemented.

1. Uniformly $^{32}P$-labeled Chlorella cells were further grown in a standard "cold" medium and aliquots of the algal cells were taken out at the beginning of, and at intervals during the culture, and subjected to analyze the contents of $^{32}$ P and total P in various fractions of the cell constituents. 2. When the $^{32}P$--labeled algae were grown in a normal "cold" medium, the P-contents in the fractions of DNA and protein increased. In the meantime the $^{32}P$- in acid-insoluble polyphosphate fraction decreased considerably, while that in RNA-polyphosphate complex significantly increased. 3. It was inferred that, under the experimental conditions of the present study, the phosphorus in polyphosphate seems to be transferred to RNA polyposphate complex and the phosphorus used in the synthesis of DNA and protein was, directly or indirectly, taken from those fractions above.ose fractions above.

Background: The aim of this study was to analyze the total phenol and total flavonoid contents and antioxidant activity of steam-treated leaves and rhizomes of Polygonatum sibiricum Redoute. In addition, we aimed to confirm their potential use as cosmetic materials by investigating their anti-aging and skin-whitening activity. Methods and Results: The leaves and rhizomes of P. sibiricum were treated with steam at different temperatures for different durations, and the antioxidant activity (DPPH and ABTS radical scavenging activity) and total phenol and total flavonoid contents of each sample were tested. The steam temperature and treatment duration siginificantly affected the antioxidant activity and, total phenol and total flavonoid content of the leaves and rhizome of P. sibiricum. Treating the P. sibiricum samples with steam at 120℃ for 12 h, yielded higher total phenol and total flavonoid contents. Comparatively, the samples treated with steam at 120℃ for 12 to 24 h showed significantly higher antioxidant activity. Further, the steamed samples of P. sibiricum demonstrated collagenase and tyrosinase inhibition activity, which indicated their anti-aging and skin-whitening properties. The samples steamed at 120℃ for 12 h, exhibited higher collagenase and tyrosinase inhibition activity. Conclusions: Leaves and rhizomes of P. sibiricum steamed at 120℃ for 12 h, showed highest antioxidant activity and, total phenol and total flavonoid contents than all other samples. Our results indicate the potential of using P. sibiricum as a cosmetic material by confirming its excellent anti-aging and whitening activity.

Five kinds of red wine from three different grape varieties, such as Gerbong (G), Campbell (C), Moru (M), Gerbong+Moru (70:30, GM), and Gerbong+Campbell(70:30, GC) were prepared in the year of 2000. The total phenolic content and color changes were monitored using hunter colorimeter and spectrophotometry methods during wine processing. The total phenolic content of Gerbong (G), Campbell (C), Moru (M), Gerbong+Moru(70:30, GM), and Gerbong+Campbell(70:30, GC) were 712.6 mg/L, 3472.9 mg/L, 2209.4 mg/L, 2019.4 mg/L, and 1184.5 mg/L, respectively. Between total phenolic content and hunter colorimeter value (L, a, and b) of red wine showed no significant difference, but that of spectrophotometry color value (hue and intensity) were significantly different (p<0.001). The total phenolic content, hue, and intensity values represented significantly different between grape varieties (p<0.01, p<0.001). the hue showed a negative correlation relationship $(r^2=0.8660,\;p<0.0001)$, and that of intensity was a positive $(r^2=0.8304,\;p<0.0001)$ between total phenolic contents. The total phenolic content of red wine could be estimated simply using these equations, $Y_{Total\;phenolic\;content\;(mg/L)}=3319.3-X_{Hue}/2208.36,\;and\;Y_{Total\;phenolic\;content\;(mg/L)}=1230.97-X_{intensity}/98.93$

This study investigated the inactivation of the total coliform, an indicator organism in chlorine dioxide, in order to assess the optimal disinfection procedure for drinking water treatment and distribution systems. This research focus on a number of factors, including the dosage of disinfectant, contact time, pH, temperature and DOC. Water samples were taken from the outlet of a settling basin at a conventional surface water treatment system. As the pH increased in the range of pH 6-9, the bactericidal effects of disinfectants decreased. Changes in levels of pH did not significantly after the disinfection effect of chlorine dioxide for total coliform. With an increase in temperature, there was a subsequent increase in the bactericidal effects of disinfectants. Thus, it is evident that a decrease in temperature will higher the CT values required to inactivate coliform for during the winter. DOC addition can also reduce total coliform inactivation. DOC is the most significant variable in total coliform inactivation with chlorine dioxide.

Contents and distribution of amino acids in the humic acid and fulvic acid fractions of different types ($R_p$, B, A, P) were investigated. Extracted humic and fulvic acids were purified and analyzed. The results are summarized as the following: (1) Composition of Humus The total humus ($H_T$), amount of humic acid (a), amount of fulvic acid (b), and ${\Delta}logK$ all decrease in the order of $R_p$ > B > A > P type. The same trend was observed in the total nitrogen and carbon. (2) Contents and composition of amino acids in humic acids. 1) The total amounts of amino acids in the humic acid fraction of different types were in the following order for soils under coniferous forest trees: $R_p$ > B > A > P type, but for soils under deciduous forest trees the order was P > A > $R_p$ > B type. There were positive correlationships between total amino acids and total carbon and ${\Delta}logK$ for humic acids from soils under coniferous forest trees, but a negative correlationship was existed. between total amino acids and C/N ratios. No significant correlation was found for samples taken from soils under deciduous forest trees. 2) The ratios of one group of amino acids to the others were compared. The ratios of acidic amino acids were in the order of P > $R_p$ > B > A type. those of neutral amino acids followed the order of $R_p$ > B > A > P type and those of the basic amino acids were in the order of B > A >$R_p$ > P type for soils under coniferous forest trees. Contents of total amino acids were in the order of the neutral > the acidic > the basic amino acids. For the soils under deciduous forest trees the order of the ratio was different. Acidic amino acids followed the order of A > P > B > $R_p$ type, neutral ones followed the order of P > $R_p$ > A > B type, and the basic amino acids did the order of $$P{\geq_-}$$ A > B $$\geq_-$$ $-R_p$ type where the difference was very small. 3) In general aspartic aicd, glycine and glutamic acid were the major components in all samples. Histidine, tyrosine and methionine belonged to the group contained in a small amount. (3) Contents and composition of amino acids in fulvic acids. 1) The total amounts of amino acids of different types of fulvic acids were in the order of $R_p$ > B > P > A type regardless of origin of samples. There were positive correlationships observed between the toal amino acids and total carbon and ${\Delta}logK$ for soils under coniferous forest trees. For soils under deciduous forest trees, positive correlationships were observed among total amino aicds, total nitrogen, total humus ($H_T$), total humic aicd (a), and ${\Delta}logK$, but a negative correlationship existed between total amino acids and C/N ratio. 2) Thr ratio among acidic amino acids, neutral amino acids and basic amino acids of different types were $R_p$ > B > P > A type. In this respect there was no difference between the two soils. 3) In general glycine, aspartic acid, and alanine were the major constituents in all samples of different types, while tyrosine and methionine were contained in a small amount. Virtually no amount of arginine was measured.

Aging process can be explained by many factors. In this study, we counted complete Blood Cells (CBC) such as WBC, Lymphocytes, Monocytes, Granulocytes, RBC, HGB, and HCT of both SAM P6 and SAM P1 during the aging process. Plasma albumin, glucose, alkaline phosphatase, calcium, creatinine, inorganic phosphate, urea concentrations were also measured at the same time. In addition to these, plasma concentrations of cortisol, total T3, and total T4 were analyzed by Chemiluminescent Immunoassay. There were no change in CBC counts of SAM R1 and SAM P6 during this study. Plasma concentratins of albumin and glucose decreased significantly in SAM R1. However, plasma alkaline phosphatases and creatinine concentration in SAM P6 decreased significantly at 16 week after birth comparing to the control. Total T4 levels were siginificantly increased although cortisol and total T3 concentrations were the same in SAM R1 groups. Especially, the after birth of creatinine, alkaline phosphatase, T4 of SAM P6 at 16 week were significantly different form those of SAM R1. At 12 week after birth, pilose antler extract was given 5g/kg/day p.o. for 0, 7, 14, 21, and 30 days each in both SAM R1 and SAM P6. The RBC, HGB, and HCT levels started to increase significantly from 7 days after the dose at SAM P6 only. Total T4 conectrations were elevated gradually during the study although the antler extract administration did not prevent or inhibit the increase in total T4 concentration during the study. Therefore, the elevation of erythrocytes after administration of the extract needs to be studied in future.
