Total protein levels of 60 bovine bull sera were treasured with refractometer and the strum proteins were fractionated by cellulose acetate membrane electorphoresis and the relative amount of each fraction was measured with automatic scanning densitometer. The sixty bovine bulls consisted of 17 Charolais bulls, 28 Holstein bulls and 15 Korean bulls. Mean total serum protein level of the total bulls was $7.50{\pm}0.50(Mean{\pm}SD)$, with the mean of Charolais $7.04{\pm}0.37g/dl$, the mean of Holstein $7.62{\pm}0.40g/dl$ and the mean of Korean $7.81{\pm}0.43g/dl$. As barbital-calcium buffer was used in fractionating the bovine serum protein with cellulose acetate membrane, electric current of 0.4 mA per centimeter width of the membrane for an hour resulted in more clear separation between ${\alpha}_1$-globulin and ${\alpha}_2$-globulin than electric current of 0.6 or 1.0 mA for an hour. However ${\alpha}_1$-globulin and ${\alpha}_2$-globulin could not be measured separately with automatic scanning densitometer. Mean serum albumin level of total bulls was $3.54{\pm}0.42g/dl$, with the mean of Charolais $3.42{\pm}0.26g/dl$, the mean of Holstein $3.69{\pm}0.38g/dl$ and the mean of Korean $3.39{\pm}0.55g/dl$. Mean serum ${\alpha}$-globulin level of the total bulls was $0.62{\pm}0.14g/dl$, with the mean of Charolais $0.61{\pm}0.07g/dl$, the mean of Holstein $0.60{\pm}0.11g/dl$ and the mean of Korean $0.67{\pm}0.23g/dl$. Mean ${\beta}$-globulin level of the total bulls was $0.85{\pm}0.21g/dl$, with the mean of Charolais $0.74{\pm}0.11g/dl$, the mean of Holstein $0.83{\pm}0.14g/dl$ and the mean of Korean $1.02{\pm}0.30g/dl$. Mean serum ${\gamma}$-globulin level of the total bulls was $2.48{\pm}0.45g/dl$ with the mean of Charolais $2.27{\pm}0.37g/dl$, the mean of Holstein $2.48{\pm}0.44g/dl$ and the mean of Korean $2.72{\pm}0.47g/dl$.

To assess the clinical and nutritional status of long-term survivors of biliary atresia, history taking, medical record review, physical examination (height, weight, MAC, TSF), blood tests (LFT, prothrombin time, platelet count, prealbumin, calcium) and liver needle biopsy were performed in 12 patients in whom Kasai procedure were performed more than 10 years ago at Department of Pediatric Surgery in Seoul National University Hospital. None were below the 5th percentile in height and weight. TSF was above the 75th percentile in all patients and showed good subcutaneous fat deposition. MAC was above the 5th percentile in all patients. Serum prealbumin level was abnormal in 2 patients with abnormal liver function and revealed visceral protein malnutrition. Serum calcium level was decreased below normal range in 4 patients with abnormal liver function. One patient had mild ascites. Five patients had abnormal liver function and 7 patients showed clinical manifestation of portal hypertension. Liver needle biopsy was performed in 5 patients and no cirrhotic change was observed. Although some patients who have survived for more than 10 years after Kasai procedure developed protein malnutrition and vitamin deficiencies, growth and development and nutritional status were generally satisfactory. Five patients(42%) showed normal liver function and no portal hypertension. In conclusion, Kasai procedure is satisfactory as a primary treatment in biliary atresia but significant portion of long-term survivors had abnormal liver function and portal hypertension. Continuous and careful follow-up is necessary to determine when liver transplantation may be indicated.

Curcumin (CMN) is known to have beneficial role in anorexia, coryza, cough, diabetic wounds, and hepatic disorders apart from its inherent antioxidant effects. Therefore, the present study was aimed to evaluate antioxidant effect of CMN in prevention of nephrolithiasis in rats-induced by ethylene glycol (EG) and Vitamin D3 (Vit. D3). Male Wistar rats (175 - 200 g) were randomized in groups like control, EG + Vit. D3 induced nephrolithiatiatic rats, CMN treated rats, CMN + EG + Vit. D3 treated rats, Vit. E + EG + Vit. D3 treated rats. Urine was collected weekly throughout the experimental protocol and estimated for calcium oxalate (CaO) count. After completion of experimental protocol serum was estimated for blood urea nitrogen and creatinine. Both the kidneys were excised and used to evaluate levels of biomarkers of oxidative stress and calcium oxalate crystal deposition by histopathological studies. Administration of EG and Vit. D3 to rats resulted in increased oxidative stress, hyperoxaluria and renal deposition of CaO crystals. Supplementation with CMN improves kidney function, reduces elevated oxidative stress, urinary oxalate level and renal deposition of CaO which shows its protective action in nephrolithiasis. The increased deposition of stone in the kidney and stone forming constituents of nephrolithiatic rats were effectively lowered by treatment of CMN.

본 연구는 고칼슘멸치가 흰쥐의 칼슘대사에 미치는 영향을 조사하기 위해 수행되었다. 실험처리는 시유와 칼슘강화우유, 칼슘강화소재(탄산칼슘, 젖산칼슘) 및 고칼슘대멸 등 5처리군으로 하였고, 대멸분말의 칼슘함량을 고려하여 최종식이의 칼슘함량은 1%가 되도록 semi-purified diet(AINdiet)에 혼합한 식이를 5주 동안 급여하였다. 대퇴골의 길이는 대조군인 우유군(M)와 칼슘강화우유군(M2)이 실험군 중 통계적으로 유의하게 길었고(p<0.05), BMD, BMC 및 칼슘함량은 고칼슘멸치군(MA)이 실험군 중 가장 높았다. 체외(in vitro) 칼슘흡수율은 고칼슘대멸군이 7.30%로 가장 높았고, 생체내(in vivo) 칼슘흡수율은 실험군간 차이는 없었지만 고칼슘대멸군이 27.50%로 가장 높았다. 혈청 중 총 콜레스테롤과 HDL-콜레스테롤 농도는 대조군과 고칼슘대멸군간에 통계적인 차이가 있었다(p<0.05). Creatinine 농도는 대조군, 고칼슘대멸군 및 탄산칼슘군이 칼슘강화우유군에 비해 통계적으로 높았다(p<0.05). 칼슘과 osteocalcin 농도 및 ALP활성은 실험군간에 차이가 없었지만 고칼슘대멸군이 높았다. SGOT활성은 칼슘강화우유군에 비해 대조군, 고칼슘대멸군 및 탄산칼슘군이 유의하게 높았다(p<0.05). 이상의 결과에서 고칼슘대멸군은 칼슘강화소재와 칼슘강화우유에 비해 대퇴골의 BMD, BMC 및 칼슘함량을 증가시켰으며, 생체내외(in vivo, in vitro) 칼슘흡수율에서도 다른 처리군보다 높았다. 본 결과는 대멸을 활용한 고칼슘식품 개발에 유용한 평가 자료로 활용될 것으로 사료된다.

본 연구는 흰쥐의 난소제거로 유발한 골다공증에 대한 흥화씨(Carhamus inctorius L)의 투여 효과를 알아보기 위하여 혈청내 호르몬과 골소주의 변화를 관찰하였다 실험동물은 4개월 령의 흰쥐를 난소절제를 실시하여 골다공증을 유발 시킨 후 실험에 이용하였으며 30일간 격일 간격으로 0.03g/kg의 용량을 투여 하였다. 혈청 내에서 Insulin-like Growth Factors, Insulin-like Growth Factor binding protein-3 (IGFBP-3), Estrogen, Bone-specific alkaline phosphotase, Calcium, and Phospotase를 매 10일 간격으로 측정하였으며 비골의 골간을 채취하여 조직 형태학적인 검사를 실시하였고 체중에 대한 대퇴골 무게를 측정하였다. 홍화씨 투여 10일과 20일에서는 혈청내 IGF-I, IGF-II그리고 IGFBP-3의 변화는 대조군에 비하여 유의성 있는 변화를 관찰할 수 없었으나 홍화씨 투여 30일에 있어서는 IGF-I, IGF-II그리고 IGFBP-3의 변화가 대조군에 비하여 현저히 높은 유의서 있는 변화를 관찰할 수 있었다(p<0.05). Bone alkaline phosphatase(BALP)에 있어서도 홍화씨 투여 30일 에 가장 많은 변화가 있었으나 estrogen과 체중에 대한 대퇴골의 무게에 있어서는 유의성 있는 변화를 관찰하지 못했다. 오히려 이시기에 난소를 절제하지 않는 대조군의 estrogen치가 높게 나타났다. 난소절제로 골다공증을 유발시킨 흰쥐에 있어서 흥화씨의 투여는 혈청내 IGFs, IGFBP-3 and BALP을 높임으로서 골다공증 치료에 효과가 있는 것으로 사료됩니다.

This investigation studied the relationship between Body Mass Index(BMI) and dietary intake, levels of serum lipid, lipoprotein(a) and plasminogen activator inhibitor-1(PAI-1) of 28.449 Korean adults(16.937 men, 11.542 women) from 1995 to 1999. The dietary assessment was conducted using 24-hour dietary records and food frequency questionnaires. During this five year study, the BMI normal-weight group, as a percentage of the annual test population, decreased from 68.0% to 60.2%, while the BMI overweight and obese groups collectively increased from 25.0% to 29.7%. The levels of serum total cholesterol (TC), LDL-cholesterol(LDL-C), Triacylglycerol(TG) and PAI-1 increased as the values of BMI increased, while the levels of HDL-cholesterol(HDL-C) and lipoprotein(a)(men only) appeared to decrease as values of BMI increased. The levels of daily energy intake also increased as values of BMI increased in both men and women. The obese group had significantly higher levels of carbohydrate, protein, fat(men only), and cholesterol intake than those of the normal-weight, underweight, and overweight groups. In men, BMI positively correlated with the levels of macronutrients and cholesterol intake(p＜0.001), % energy of protein, fat, and alcohol intake(p＜0.001), and the levels of serum TC, LDL-C, TG and PAI-1(p＜0.001), while BMI negatively correlated with % energy of carbohydrate intake, and the levels of Lp(a) and HDL-C(p＜0.001). In women, BMI negatively correlated with level of cholesterol(p＜0.01), fat(p＜0.001), alcohol intake(p＜0.05),% energy of fat (p＜0.001), % energy of alcohol intake and level of and HDL-C(p＜0.001). Subjects who had serum TC, LDL-C, HDL-C, and TG levels greater than the standard reference values(TC＞240mg/㎗, LDL-C＞130mg/㎗, HDL-C＞35, TG＞200mg/㎗) exhibited a higher intake of the three macronutrients, iron, calcium, meat, milk and fatty foods than those subjects who had serum lipid concentrations less-than-or-equal-to the standard reference values. Overall, there was positive correlation between the high risk factors of vascular disease variables, dietary intake, and BMI. Prevalence of hypertension and high blood sugar were increased as BMI increased, but the prevalence of hypertension is decreased as the year goes by. These findings showed that dietary intake, level of serum lipids and other vascular disease risk factors increased as BIM increased. Therefore, middle or upper class Korean adults who have high BMI should improve their eating habits. This involve reducing alcohol, animal fat, high carbohydrate foods, and overall food intake, and balancing intake in order to lower vascular disease risk factors, including obesity.

Aging is characterized by an age-dependent reduction in bone density. Pronounced bone loss by postmenopausal estrogen deficiency induces a bad effect on dynamic balance of bone metabolism. When the bone density is reduced to the level below the fracture threshold, the risk for fracture is greatly increased. The purpose of this study is to examine what are the effects of the Guisinhwan(GSH : 歸腎丸) on the ovariectomized rat model of postmenopausal osteoporosis. The results of the experiment are as follows: Body weight in control group showed significant increase in comparison with sham, but that in GSH-treated showed no change in comparison with control. The level of serum albumin in control group showed significant decrease in comparison with sham. That in GSH-treated was slightly decreased in comparison with control. The level of serum ALP activity in control group showed significant increase in comparison with sham, but that in GSH-treated was significantly decreased in comparison with control. The level of serum phosphorous, calcium, GOT, GPT, T3 did not significant change among the three groups. The level of serum estrogen in control group showed slightly decreased in comparison with sham, but that in GSH-treated showed no change in comparison with control. The level of serum T4 in control group showed significant increase in comparison with sham, but that in GSH-treated was significantly decreased in comparison with control. Trabecular bone area as well as trabecular thickness in control group showed significant decrease In comparison with sham. Those in GSH-treated showed significant increase in comparison with control. Trabecular number did not significant change among the three groups. Trabecular separation only in GSH-treated showed significant decrease in comparison with control. Osteoclast number in control group showed significant increase in comparison with sham. That in GSH-treated showed significant decrease in comparison with control. Oseoblast surface in control group showed significant increase in comparison with sham, but that in GSH-treated showed no change in comparison with control. According to the above these results, GSH has shown to be capable of preventing and curing osteoporosis caused by old-aged and postmenopause.

Sixty healthy growing pigs ($Duroc{\times}Landrace{\times}Yorkshire$ with an average BW of 21.4 kg) were used to determine the true digestible phosphorus (TDP) requirement of growing pigs on the basis of growth performance and serum biochemical indices. Pigs were assigned randomly to one of five dietary treatments (12 pigs/diet), representing five levels of TDP (0.16%, 0.20%, 0.23%, 0.26% and 0.39%). There were three replications per treatment, with four pigs (2 barrows and 2 gilts) in each replication (2 pigs/pen) A randomized-block design was used, with pen as the experimental unit. Experimental diets were formulated to provide the 5 TDP levels with a total calcium (Ca) to TDP ratio of 2:1, and offered to pigs at 5% BW for 28 d. The total Ca contents of the five diets were 0.33, 0.38, 0.45, 0.51 and 0.79%, respectively. During the 28-d experimental period, the ADG of pigs was affected by dietary TDP levels as described by Equation 1: y = $-809,532x^4+788,079x^3-276,250x^2+42,114x-1$,759; ($R^2$ = 0.99; p<0.01; y = ADG, g/d; x = dietary TDP, %). The feed:gain ratio for pigs was affected by dietary TDP levels as described by Equation 2: y = $3,651.1x^4-3,480.4x^3+1,183.8x^2-172.5x+10.9$ ($R^2$ = 0.99; p<0.01; y = feed:gain ratio; x = dietary TDP, %). Total P concentrations in serum were affected by dietary TDP levels as described by Equation 3: y = $-3,311.7x^4+3,342.7x^3-1,224.6x^2+195.6x-8.7$ ($R^2$ = 0.99; p<0.01; y = total serum P concentration and x = dietary TDP, %). The highest ADG (782 g/d), the lowest feed:gain ratio (1.07), and the highest total serum P concentration (3.1 mmol/L) were obtained when dietary TDP level was 0.34%. Collectively, these results indicate that the optimal TDP requirement of growing pigs is 0.34% of the diet (e.g., 5.1 g/day for a 30-kg pig that consumed 1.5 kg feed daily) at a total Ca to TDP ratio of 2:1.

This study was conducted to investigate dietary and other factors affecting bone mineral density (BMD) in Korean premenopausal women. Seventy-eight premenopausal women who visited health promotion center for health examinations volunteered to participate in this study and they were divided into two groups according to the bone status by T-score : normal or osteopenic group and osteoporotic group. The demographic and general characteristics, and dietary intake were surveyed using the questionnaire. BMDs of the lumbar spine and femoral neck of subjects were measured by dual energy X-ray absorptiometry. Serum samples were measured for Lipid concentration, and calcium, phosphorus, alkaline phosphatase as bone formation indicators. Urine was analysed for creatinine as bone resolution indicators. The results are as follows:The mean BMDs of the lumbar spine and femoral neck were 1.21 0.02g/cm$^2$ and 0.97 0.04g/cm$^2$, respectively and the BMD levels of osteoporotic group were significantly lower than that of normal or osteopenic group (p<0.001, respectively). Height in osteoporotic group was significantly lower than that of normal or osteopenic group (p<0.01), and bodyweight did not show any significant difference but had a lower tendency. Mean daily intake of energy was 1720 52ka1. When nutrient intake was compared with recommended dietary allowances (RDA) of subjects, calcium, Fe, vitamin A and riboflavin intakes showed means lower than RDA. The nutrient intake did not show any significant difference between normal or osteopenic group and osteoporotic group except intakes of protein fat and niacin. Serum and urine levels did not show any significant differences between normal or osteopenic group and osteoporotic group and all were within normal range, however, serum alkaline phosphatase level of osteoporotic group was significantly higher than that of normal or osteopenic group (p<0.001). Height showed positive correlations with lumbar spine bone mineral density (LBMD, r=0.332, p<0.01), no correlation was found with femoral neck bone mineral density (NBMD). Age, age at menarche, bodyweight, body mass index (BMI) and obesity showed no correlation with BMD. The BMD of the lumbar spine was significantly and positively related to the intake of niacin and vitamin C (r=0.236, p<0.05; r=0.274, p<0.05). Serum levels of calcium and phosphorus showed a negative correlation with LBMD (r=-0.698, p=0.0001; r=-0.503, p=0.0001, respectively). The results suggested that the BMDs of the lumbar spine was positively related to the intake of niacin and vitamin C in premenopausal women. Therefore, this study confirmed that one of the most effective way to minimize bone loss would be higher intake of niacin and vitamin C rich foods and habitual physical activity may have a beneficial effect on BMD in premenopausal period.
