Morus alba extract(MAE) was tested for its ability to inhibit alloxan induced lipidperoxidation. Lipid peroxide contents in serum, liver, kidney and heart were measured by the TBA method. ICR mice receiving alloxan at a dose of 6mg/kg intraperitoneally after a 24hrs starvation showed significantly increased lipid peroxide contents as compared to untreated control. Lipid peroxide contents in serum, liver, kidney of alloxan-diabetic mice were decreased by the treatment of MAE at the dose of 50mg/kg, 100mg/kg for 7 days.

The objective of this study was to investigate the use of extract from mesenteric lymph nodes as an alternative to serum for ELISA to detect Salmonella antibodies in slaughter pigs. Among 324 slaughter pigs, 65 (20.1 %) were positive in the serum ELISA and 76 (23.5%) were positive in the ELISA with extract from lymph nodes. A total of 24 (7.4%) Salmonella representing 6 serotypes were isolated from mesenteric lymph nodes and 35 (10.8%) Salmonella belonging to 2 serotypes were also recovered from cecal contents of slaughter pig samples, respectively. The most prevalent serogroup was B (55.9% of isolates) and serotype was Typhimurium (52.5% of isolates). In the comparison of the results of between the serum ELISA and Salmonella isolation, kappa value was 0.28 with mesenteric lymph nodes and 0.37 with cecal contents, respectively. However, the extract ELISA had sensitivity of 98.5%, specificity of 95.4% and kappa value of 0.88 as compared with the serum ELISA. Because high degree of concordance between the serum ELISA and the extract ELISA was observed (P=0.24), extract from lymph nodes could be used as an alternative to serum for the detection of Salmonella antibodies in the ELISA.

The nutritional survey and blood sampling was conducted from May 23 to 27, 1971, in order to investigate the state of the nutritional intake in relation to blood contents of rural women. This survey covered a total of 47 women residing in Youngam-gun, Cholla-namdo, Korea. The daily diet of these subjects was observed by 24-hour recall method and weighing method for 3 days and hemoglobin (Hb), hematocrit(Hct), mean corpuscular hemoglobin concentration (MCHC), serum protein, serum albumin, A/G ratio, serum iron, total iron binding capacity (TIBC), transferrin saturation (TS), serum cholesterol and blood specific gravity (SG) were measured. The results were summarized as follows ; The rate of intake of vegetable foods was high, especially cereals, and that of animal foods was low, especially eggs and milk and milk products. The daily intake of niacin was sufficient, and the intakes of energy and iron were also tend to be adequate. On the contrary, the intakes of vitamin A, $B_2$ and C, calcium and protein were insufficient. The mean red blood cell number was $410.8{\pm}26.4{\times}10^{4}/mm^{3},$ the mean values of Hb, Hct and MCHC were $12.5{\pm}0.9gm%$, $37.5{\pm}2.4%$ and $33.2{\pm}0.5%$ thus the anemic prevalences were 21.3%, 12.8% and 93.6% comparing with the anemic criteria of WHO. The levels of serum protein and serum albumin were $7.1{\pm}0.4gm\;%$ and $4.3{\pm}0.3gm\;%$so the A/G ratio was indicated $1.6{\pm}0.2.$. The levels of serum iron and TIBC were $91.9{\pm}27.5{\mu}g/100ml and $297.5{\pm}31.4{\mu}g/100ml,$ so TS was calculated $31.2{\pm}9.7\;%$. The mean value of SG was $1.044{\pm}0.002,$ and the level of serum cholesterol was $164.3{\pm}25.4mg/dl$. In the relation between each of bloood content, Hb showed positive correlation not only with Hct but also protein at the level of significance of 1 per cent and 5 per cent, and protein also showed a positive correlation with serum cholesterol at the 1 per cent level of significance. In the relation between the nutrient intake and blood contents, vitamin C intake showed a positive correlation with Hb, serum protein and serum iron at the level of significance of 1 per cent, iron intake also showed a positive correlation with serum iron and serum cholesterol at the same significant level, and protein intake showed a positive correlation with serum iron at the at the level of significance of 5 per cent.

This study was carried out to examine how dietary protein and calcium levels in rats fed fat-enriched diet affect the total lipid and cholesterol contents of blood and tissues. Male Sprauge-Dawley rats weighing approximately 200g were fed six purified diets which contained 18%(w/w) beef tallow, 1% (w/w) cholesterol, two source of protein, casein or isolated soy protein (ISP) and three levels of dietary calcium, 0.1%, 0.4% and 1.0%, first, for four weeks, and second, for eight weeks. The contents of the total lipid, cholesterol and triglyceride in blood, liver, heart and feces were determined. After four weeks feeding serum lipid and cholesterol concentrations significantly decreased in rats fed 1.0% (w/w) level calcium, regardless of dietrary protein sources. After eight weeks, these concentrations were significantly lower in the rats fed soy protein than in casein-fed rats. As dietary calcium level increased serum and tissue lipid and cholesterol contents were decreased and fecal lipid excretion increased. It is concluded that hypolipidemic and/or hypocholesterolemic effects of soy protein and calcium were partly due to decrease in lipid absorption.

This study was conducted to investigate the effect of late-harvested green tea extract on serum and tissue lipid contents and Ca absorption. Sprague-Dawley male rats weighing 200g were fed high fit diets containing no tea(control), 0.5%(0.5LG), 1.0% late-harvested green tea extract(1.0LG), and 1.0% early-harvested green tea extract(1.0EG) for 4 weeks. Though daily food intake of experimental groups showed no significant difference from that of control group, daily body weight gain and food efficiency ratio were lower in all groups fed green tea extract. The contents of serum triglyceride of 1.0LG and 1.0EG groups and the content of serum total cholesterol of 1.0LG group were significantly lower than those of control group. The values of serum HDL-cholesterol in groups fed green tea extract were higher than that in the control group. LDL-cholesterol and atherogenic indices of all groups fed green tea extract were significantly lower than those of the control group. The contents of total lipid and triglyceride in liver were significantly lower in only 1.0LG group. For epididymal fit pad, the contents of total lipid and triglyceride in 1.0LG and 1.0EG groups were lower than those in the control group. The contents of total lipid excreted in feces were higher in groups fed diets of 1.0% green tea extract. There was no significant difference among experimental groups in Ca absorption. These results suggest that the administration of late-harvested green tea extract decreases the contents of fat in the body without reducing Ca absorption.

In this paper, the influences of adrenergic neuronal blockades of different mode: guanethidine and ${\alpha}$-methyl-para-tyrosine on the changes induced by carbon tetrachloride $(CCl_4)$ of hepatic total lipid, glycogen, and lipid peroxide contents and serum lactic dehydrogenase activity were investigated in male mice. The results obtained were summarized as follows: 1) The hepatic total lipid and lipid peroxide contents and serum lactic dehydrogenase activity were markedly increased by $CCl_4$, but hepatic glycogen content were decreased. 2) The hepatic total lipid and lipid peroxide contents and serum lactic dehydrogenase activity were not significantly changed by guanethidine(20mg/kg) or ${\alpha}$-methyl-para-tyrosine (5 mg/kg) injection. 3) The increase of hepatic total lipid induced by $CCl_4$ was inhibited by the pretreatment of guanethidine or ${\alpha}$-methyl-para-tyrosine, and the increase of hepatic lipid peroxide content induced by $CCl_4$ was slightly inhibited by them. But the decrease of hepatic glycogen content and the increase of serum lactic dehydrogenase activity induced by $CCl_4$ were not affected by them.

The present study was designed to investigate the serum cholesterol lowering effect oj the phytosterol derivative (LPSS) on high cholesterol (HC) diet-induced hypercholesterolemia in male weaning Sprague-Dawley (SD) rats. Rats were fed with HC diet containing 1 % cholesterol and 0.5% cholic acid for 1 week. After 1 week, the LPSS oil suspension (0.32 g/kg B. W.) was orally administered to the rats fed with either basal diet or HC diet groups for 7 days. In addition, the LPSS powder (0.14%) mixed with basal diet or HC diet was Jed to the rats for 7 days. Serum total cholesterol and LDL-cholesterol contents were not altered by administration of the LPSS oil suspension with basal diet. However, they were significantly decreased by administration of the LPSS oil suspension with HC diet at day 14. Also, they were significantly decreased by the LPSS powder mixed with basal diet or HC diet at day 9, 11, 14. HDL-cholesterol contents were not altered by the LPSS oil suspension or LPSS powder. These results indicated that the phytosterol derivative(LPSS) might decrease serum total cholesterol and LDL-cholesterol contents in rats.

The correlation between maternal lipid nutritional status during pregnancy and gestational length was investigated. Subjects consisted of 30 full-term delivery mothers, 30 preterm delivery mothers, and babies of both groups. Dietary fat intake during pregnancy and serum lipid levels in mother and umbilical serum were measured. The mean daily intake levels of fatty acid during pregnancy were lower than the recommended dietary allowances, while $\omega$6/$\omega$3 ratios of dietary fatty acids were acceptable. For preterm delivery mothers, fatty acid intake levels to be lower than those in full-term delivery mothers, especially DHA intake of these two groups was significantly different. During gestation, hyperlipidemia was apparent in the pregnant women. The serum lipid contents of preterm delivery mothers tended to be lower than those of full-term delivery mothers, and umbilical cord serum lipid contents of the preterm delivery group tended to be higher than those of the full-term delivery group. Total cholesterol levels in the umbilical cord serum of preterm babies were significantly higher than those of full-term delivery group. On the other hand, total cholesterol and HDL-cholesterol levels between umbilical cord serum and maternal serum were positively correlated in the preterm delivery group. Concerning, energy and fatty acid intakes were more closely associated with umbilical cord serum lipid levels in full-term babies, but negatively associated in preterm babies. It was concluded that gestational length was related to the dietary intake of fatty acids such as DHA in pregnant women. For better understanding, the ralationship between placental lipid transport mechanisms and gestational length needs to be explored.
