The purpose of this study was to evaluate the effect of a weight control program on anthropometric values, serum lipid profiles and nutrient intakes. The subjects of this study were 38 obese children (boy : 17, girl : 21) with obesity index over 120%. The weight control program for obese children included nutritional education (50 min) and exercise (50 min) for 10 weeks. The nutrition intakes of the children were surveyed before and after the weight control program by 24hr recall test. The BMI, R$\ddot{o}$hrer Index, Obesity Index, WHR (Waist - Hip ratio) and body fat(%) were significantly decreased after completion of the weight control program. The total cholesterol and HDL-cholesterol of subjects were significantly increased after the weight control program. Distribution of serum lipid profiles was slightly changed. The energy intakes were significantly decreased (p < 0.001). from 1760.8 kcal to 1435.2 kcal. In addition, the intakes of P, Zn, retinol, vitamin $B_1$, vitamin $B_2$, vitamin E and niacin were significantly decreased. while intakes of vitamin C and folate were increased. Calcium and folic acid were upper 25% of subjects, under EAR(Estimated Average Requirements) intake before the weight control program. The distribution of energy intakes was significantly changed into positive status; fat percentage was decreased 26.3% to 22.1% (p < 0.01). Carbohydrate was increased 58.6% to 61.2% (p < 0.05). Meal distribution of energy intakes was changed; calorie percentage from lunch significantly increased from 32.2% to 38.3%. Calorie percentage from snack significantly decreased from 17.7% to 13.5%. In conclusion, weight control program for 10 weeks is effective in obesity index and nutrient intakes although serum lipid values were a little changed.

Thirty-day-old seedlings of tomato (Lycopersicon esculentum) were treated with different concentrations of HgCl$_2$(0. 10 and 50 $\mu$M) for up to 20 days. and the detailed distribution of Hg absorbed and its toxicity in different plant parts (roots, stems and leaves) were investigated. The accumulation of Hg in plants increased with external Hg concentrations. and Hg is strongly retained by roots. Further. Hg content in leaves was various. showing more accumulation in older leaves. Seedlings exposed to toxic levels of Hg showed not only the reduction of dry weight and length of both shoot and root. and chlorophyll levels in leaves but also the enhancement of malondialdehyde (a lipid peroxidation product) formation in all plant parts investigated. These results suggest that physiological impairment of a plant exposed to Hg may be achieved by internal distribution of Hg absorbed and Hg-induced oxidative stress in different plant parts.

Formation, cellular distribution and structural changes of storage lipid, and active site and cellular localization of lipase in endosperms and cotyledons of lipid-rich seeds such as Helianthus annuus, Ricinus communis and Pinus koraiensis, and in those of starch-rich seeds such as Pisum sativum and Zea mays were investigated in relation to the seed development by cytochemical methods. In endosperms and storage cotyledons of lipid- and starch-rich seeds after seed-gathering, there were widely distributed storage material which was composed of spherical protein bodies, spherosomes, and starch granules. But cellular organelles were hardly observed in the cytoplasm. Staining pattern of vesicles released from SER, and of low electron dense membraneous granules, which were perhaps at an early stage of spherosomes, were the same as in the spherosome. Electrondense granules released from RER were observed in the vicinity of plasma membrane. As a result of lipid staining, the spherosomes were more electron dense and were uniform as compared with the protein matrix within the protein body and cytoplasmic proteinaceous granules. The major component of the spherosome was determinated to be lipid. Spherosomes and vesicles containing SER-released materials showed the same as in the electron density. Lipase activity was especially strong in the inner region and on the surface of decomposed spherosomes and near the plasma membrane.mbrane.

In this paper, we report a new cationic lipid composed of L-lysinamide and cholesterol as a potent gene delivery vector. $3{\beta}$[L-Lysinamide-carbamoyl] cholesterol could self-assemble with plasmid DNA forming discrete lipoplexes. From atomic force microscopic images of the complexes, the size distribution was observed to range from 100 to 150 nm in diameter. The transfection efficiency of this amphiphile on different cell lines was evaluated as a micellar solution in the absence of the fusogenic helper lipid, dioleoyl phosphatidyletbanolamine (DOPE). Transfection experiments were performed as a function of charge ratio (lipid/DNA) and transfection time. Cytotoxicity and in vitro transfection efficiency of the amphiphile was demonstrated and compared with those of commercially available Lipofectin and polyethylenimine (PEI).

This study was designed to investigate the effect of potato lipoxygenase on the change of dough chemical composition including lipid distribution, fatty acid composition, carotenoids content and color value in wheat flour dough. For the study, the potato lipoxygenase was added to wheat flour at a level of $6.5{\times}10\;unit/g$ flour. The addition of potato lipoxygenase to wheat flour dough was found to cause an increase in free lipid content, an effect apparently related to the decrease in linoleic acid content and increase in peroxide value. This phenomena might be due to the enzymatic oxidation of polyunsaturated fatty acid. Also, the bleaching effect of lipoxygenase was observed as the decrease in carotenoids content of wheat flour dough. In comparison of color value, it was shown that redness, yellowness and total color difference$({\delta}E)$ were lower by addition of lipoxygenase.

1. Back ground and purpose An experimental study has done to examine the effect of defense and cure gastric mucasal damage of Mokdan-pijihwang-tang. 2. Methods Mice had intragastric injected with MJ extract before indomethacin treatment which induces homorrhage infarct and erosion artificially. Degree of lipid peroxidation, general morphology, change of mucous cell, the distribution of PNA, ICAM and distribution of apoptotic cell were objected. (Abbreviation) MJ : Mokdanpijihwang-tang, PNA : Peanut Agglutinin, ICAM : Intercellular Adhesion Molecule 3 Results 1) The degree of lipid peroxidation in INDO-group had increased conspicuously than control group. But the degree of lipid peroxidation in MJ-group had decreased than INDO-group and these decline had probability. 2) After indomethacin treatment, hemorrhage infarct and erosion had increased in stomach body. But in MJ-group, the configuration is normal, except the group intragastric injected with MJ extract at hour 24 before indomethacin treatment. 3) Surface mucous cell and neck mucous had disappeared in INDO-group. But in MJ-group tormal distribution had shown like control group except the group intragastric injected with MJ extract at hour 24 before indomethacin treatment. 4) PNA positive reaction had not shown in INDO-group. But medium PNA positive reaction had shown In Mj-group. 5) ICAM positive reacted cell had shown in INDO-group. The decrease of ICAM positive cell were shown than INDO-group. 6) A number of apoptotic cell was distributed in hemorrhagic erosion. A few number of apoptotic cell was distributed in MJ-group except some surface mucous. 4. Conclusion These results suggest that MJ has an effect on cure of gastric mucosal damage.

The effects of a hypocaloric diet with or without strength training on body fat distribution and serum lipid concentrations in obese elderly women were investigated. Twenty-six healthy women (age 66±4.6 yr; body mass index 32.3±2.9 kg/m²) were randomly assigned to 3 groups: control (C; n=8), hypocaloric diet (DO; n=9) or hypocaloric diet with strength training (DST; n=9). Subcutaneous adipose tissue (SAT), visceral adipose tissue (VAT), and inter and intra muscular adipose tissue (IMAT) were measured using magnetic resonance imaging. Serum lipid concentrations including total cholesterol (TC), high density lipoprotein cholesterol (HDLC), low density lipoprotein cholesterol (LDLC), and triglycerides (TG) were measured. No significant changes occurred in body weight and percent body fat in the C group over the 16-week period. The DO and DST groups lost similar amounts of weight and fat after 16 weeks. SAT and VAT decreased after weight loss in the DO and DST groups but not in the C group. IMAT was significantly reduced in the DO and DST groups, whereas in the C group IMAT increased. The loss in IMAT mass was similar in the DO and DST groups. TC and LDLC decreased in the DO and DST groups but not in the C group. There were no differences between the DO and DST groups in decrease in TC and LDLC. HDLC decreased in the DO group but not in the C and DST groups. TG tended to decrease in the DST group. In conclusion, body fat distribution including SAT, VAT, and IMAT and serum lipid concentratons were modulated by weight loss resulting from the hypocaloric diet with or without strength training in obese elderly women. Strength training did not enhance the improvement in body fat distribution and serum TC and LDLC concentrations by the hypocaloric diet.

A dynamic cycle of addition and removal of O-linked N-acetylglucosamine (O-GlcNAc) at serine and threonine residues is emerging as a key regulator of nuclear and cytoplasmic protein activity. In this work, immunocytochemistry was carried out to investigate the subcellular expression of GlcNAc kinase (NAGK, EC 2.7.1.59) that catalyzes the phosphorylation of GlcNAc to GlcNAc 6-phosphate. Immunostainings of cultured rat hippocampal neurons revealed patchy or punctate distribution of NAGK. When NAGK is doublestained with caveolin-1 or flotillin, markers for caveolae and lipid rafts, respectively, NAGK was co-localized with these markers. These results indicate that most, if not all, of the NAGK immunopunctae represent caveolae and lipid rafts, and suggest NAGK's role in these membrane microdomains.

Introduction and Objectives : Administrating the Sopungchengyoungtanggami-bang (SCG) extract on to the atopic dermatitis(AD) is to study change of external dermal formation, change of leukocytes in vasculature, change of lipid formation in stratum corneum and distribution of ceramide and this study is done through forcing injury to rat's back skin which are lipid protect formation in stratum corneum. Materials and Methods : The AD which caused intentionally using the external application on the rat's back skin was used the SCG. The change of leukocytes in vasculature has been identified through optima 5.2 and student t-test and the results were made into dermal formation graph. Results : After dispensing SCG extract into the AD, the dermal injury was decreased. Especially, recover of lipid protection formation which include lipid and ceramide in stratum corneum is suppressing acute inflammation that some factors are PKC, TNF-${\alpha}$, IL-12B which controled the secretion of relating inflammatory cytokine, also went onto decrease of angiogenesis, and the decrease of degranulated mast cell. In addition, the decrease of epithelial injury also caused the growth of cell to decrease in stratum basale and cytoclasis. In the vasculature, the leukocytes were also decreased and it could relate to decrease AD Conclusions : Thus, SCG has effect on AD suppressing the dermal injury through recovering of lipid protection formation in stratum corneum.
