Objectives : This study was designed to investigate the effect on lipoapoptosis of Alisma orientale extract against free fatty acid-induced cellular injury. Methods : HepG2 cells were used in an vitro model. HepG2 cells were treated with free fatty acids to generate a cellular model of nonalcoholic fatty liver disease (NAFLD). Using this cellular model, the anti-apoptotic effect and reducing steatosis of Alisma orientale extract against free fatty acid-induced cellular injury was evaluated by measuring steatosis and apoptosis. Results : Alisma orientale extract significantly attenuated free fatty acid-induced intracellular steatosis. Alisma orientale extract inhibited free fatty acid-mediated activation of pJNK, PUMA, BAX, caspase-3, and -9, and apoptotic kinases that are correlated with NAFLD. Alisma orientale extract also promoted Bcl-2, a anti-apoptotic protein. Conclusions : From the above, the Alisma orientale extract decreased the hepatocyte steatosis and showed the hepatocelluar protective effect by the regulation of apoptosis-related protein. It proposes the possibility of Alisma orientale extract to the treatment of nonalcoholic fatty liver disease in clinics.

In this study, we investigated the relationship between unsaturated fatty acids influencing beef flavor and four types of SNPs (c.280A>G, c.388G>A, c.408G>C and c.456A>G) located at exon 2, 3 and 4 of the FABP4 gene, which is a fatty acid binding protein 4 in Korean cattle (n = 513). When analyzing the relationship between single genotype, fatty acids and carcass trait, individuals of GG, GG, CC and GG genotypes that are homozygotes, had a higher content of unsaturated fatty acids and marbling scores than other genotypes (p<0.05). Then, haplotype block showed strong significant relationships not only with unsaturated fatty acids (54.73%), but also with marbling scores (5.82) in $ht1{\times}ht1$ group (p<0.05). This $ht1{\times}ht1$ group showed significant differences with unsaturated fatty acids and marbling scores that affected beef flavor in Korean cattle. Therefore, it can be inferred that the $ht1{\times}ht1$ types might be valuable new markers for use in the improvement of Korean cattle.

The effect of slaughter weight and gender on fatty acid composition of homogenised rib samples of Hungarian Simmental (HS) and Holstein-Friesian (HF) cattle breeds was investigated. In the first experiment 22 Hungarian Simmental and 18 Holstein-Friesian cattle's meat, in the second experiment 15 females and 12 males Holstein-Friesian cattle's meat was analysed on fatty acid content. Saturated and mono- or polyunsaturated fatty acid profile did not seem to vary either by breed or by slaughter weight categories. The effect of gender, however, proved to be significant in influencing the quantity of polyunsaturated fatty acids, including linoleic and linolenic acids, as well as polyunsaturated fatty/saturated fatty acids (PUFA/SAFA) ratio. The amount of polyunsaturated fatty acids (PUFA) was higher in males than in females. Negative correlation was established between the quantity of PUFA and the amount of adipose tissue in rib samples.

To investigate fatty acid constituents and relative compositions in the fluid of the follicles, oviducts, uterine ho군 and uterine body in sows, the fluids of the reproductive tract were analyzed using Gas chromatography. The samples were taken from various reproductive tract of 21 sows slaughtered. 1. Caprylic acid(C8: 0), capric acid(C10:0), lauric acid(C12:0), myristic acid(C14:0), palmitic acid(C16:0), plamitolele acid(C16:1), stearic acid(C18:0), oleic acid(C18:1), linoleic acid(C18:2) and arachidonic acid(C20:4) were found in the reproductive tracts of the sows, which made 10 kinds of fatty acid intotal. 2. Two kinds of polyunsaturated fatty acids, linoleic acid and archidonic acid were found inthe reproductive tracts. 3. Palmitic acid among saturated fatty acids and oleic acid among unsaturated fatty acids were the hihgest level in all of the reproductive tracts. 4. Palmitic acid, oleic acid and stearic acid showed higher rate with 44.89%, 23.69% and 14.36%, respectively, and lauric acid, capric acid, palmitoleic acid, arachidonic acid ad myristic acid showed lower rate with 0.62%, 1.13%, 1.65%, 1.97% and 2.24%, respectively in the reproductive fluid. 5. The highest level of arachidonic acid was found in the uterine horn. 6. The sum of the palmitic acid and oleic acid were 66.91%, 70.41%, 66.14% and 73.36% in the fluid of follicle, oviduct, uterine horn and uterine body, respectively. 7. The relative composition of arachidonic acid was higher during the follicular stage than during the luteal phase in the fluid of oviduct and uterine. 8. The long chain fatty acids such as the palmitic acid, stearic acid, oleic acid and linoleic acid showed higher relative compositions during the follicular phase(93.18%∼96.83%) than during the luteal phase(82.56%∼88.37%). 9. Caprylic acid, luric acid and palmitoleic acid were undetected in the fluid of all of the reproductive tracts during the follicular phase. Low relative compositions of capric acid, myristic acid andarachidonic acid were found during the follicular phase, while the low relative compositions (<5%)of capric acid, lauric acid, myristic acid, plamitoleic acid and arachidonic acid were found during the luteal phase.

The 165 collections originated from domestic and foreign countries were tested to evaluate the fatty acid composition of sesame for using as a basic research for oil quality improvement. The Korean and American varieties were lower content in saturated fatty acid and higher especially in unsaturated fatty acids (Oleic and Linoleic acid) than those of other regions. Varieties from temperate areas were higher in unsaturated fatty acid than that of varieties from tropical areas. On the other hand, the varieties which were late matured and had yellow seed coat color and set three capsules showed higher in unsaturated fatty acids than those of early matured, white seed coat and one capsules. Since there was significantly negative correlation between unsaturated fatty acid and saturated fatty acid contents, it was possible to improve the fatty acid composition of sesame.

A lot of waterlogged shrouds and mummies have been found in tombs revered with lime of the Chosun Dynasty(1392-1910) of Korea. Shrouds were heavily polluted with greyish white material. Greyish white material, which adhered to shrouds excavated from tombs(16C and 17C), was submitted to FT-IR qualitative analysis and fatty acid analysis for cleaning. The results of the FT-IR qualitative analysis identified the main ingredient of the greyish white material as calcium salt of fatty acid, including a little of the fatty acids, lipids and proteins. Therefore the greyish white material fumed out adipocere which was formed from the degradation of the lipids in a dead body. From the fatty acid analysis, hydroxy fatty acids(10-Hydroxyhexadecanoic acid and 10-Hydroxyoctadecanoic acid), which were found in adipocere, were detected. The distribution of contents of fatty acids was also rimilar to that of adipocere which have a high proportion of palmitic acid of saturated fatty acid and a low proportion of oleic arid of unsaturated fatty acid. In view of the results of analyses, it was revealed that greyish white material adhered to shrouds was adipocere moved from a mummy.

Total lipid contents were 0.58∼3.00% in 9 kinds of brown algaes, 0.47∼2.16% in 5 kinds of red algaes and 0.55∼2.99% in 2 kind of green algeas, respectively. Fatty acid compositions of the algaes were determined by gas liquid chromatography. Total polyenes and n-3 polyenes of linoleic acid(18:3), stearidonic acid(18:4), eicosapentaenoic acid(20:5) and docosahexaenoic acid(22:6) were 3.88∼57.57% and 1.46∼25.67% in the brown algaes, 5.30∼39.75% and 1.17∼21.91% in the red algaes, and 7.76∼19.27% and 3.67%∼10.61% in the green algaes, respectirely. The fatty acid contents and compositions of total polyenes and n-3 polyenes were vary different in the algae groups and sepecies.

Fatty acid is an important component of many biological processes. However, an imbalance in diet-especially, a n-3 polyunsaturated fatty acids (PUFAs) deficiency-causes several diseases such as diabetes, cardiovascular disease and cancer. In this study, we analyzed the fatty acid contents and compositions of 26 species of Korean salt marsh plants and found high fatty acid contents from S. herbacea ($148.75\;{\mu}g$/mg-dry wt.), S. komarvii ($119.05\;{\mu}g$/mg-dry wt.), C. heterocarpa ($79.23\;{\mu}g$/mg-dry wt.), A. capillaris ($71.65\;{\mu}g$/mg-dry wt.), and L. tetragonum ($67.02\;{\mu}g$/mg-dry wt.). In the case of saturated fatty acids (SFAs) composition, palmitic acid is richest in most salt marsh plants. On the other hand, oleic acid and linoleic acid are major components of monounsaturated fatty acid and n-6 PUFA, respectively. In addition, n-3 PUFAs such as LNA (linolenic acid), EPA (eicosapentaenoic acid), and DHA (docosahexaenoic acid) known as the main fatty acid components of fish oils and seaweeds, were also found in S. herbacea, S. komarvii, T. tetragonoides, A. capillaris and G. littoralis.

The influence of different storage temperature and packaging methods on the flying cultured eel bone were investigated. The acid values, peroxide values and fatty acid composition were measured during storage 20$^{\circ}C\;and\;40^{\circ}C$ for 60 days. The lipid oxidation was rapidly progressed with the increased temperature. The addition of oxygen absorber remarkably repressed lipid oxidation during storage of the living cultured eel bone at $20^{\circ}C\;and\;40^{\circ}C$, followed by $N_{2},\;BHA,\;\alpha$-tocopherol and control. The monounsaturated fatty acid content was the highest in the frying cultured eel bone, followed by saturated fatty acid and polyunsaturated fatty acid. The major fatty acids were oleic acid, palmitic acid and linoleic acid. The saturated fatty acids increased with the rise of storage temperature and prolonging the storage period, while monounsaturated fatty acid and polyunsaturated fatty acid were decreased. The changes of fatty acid composition were the lowest in sample by packing with oxygen absorber, followed by packing $N_{2},\;BHA,\;\alpha$-tocopherol and control. from the result of sensory evaluation, sample by packing with oxygen absorber were rated as higher quality than the others.

In order to investigate the fatty acid composition of Korean pumpkins, this study was designed. Three samples of Korean pumpkins, A(yellowish ripe), B(unripe, 30 days old) and C(unripe, 20 days old) were used for fatty acid analysis by gas chromatography. The results were as follows : Pumkin C, B and A showed 10, 12 and 15 kinds of fatty acids, respectively. In case of palmitic acid(C16:0), pumpkin C, B and A showed 22.5%, 22.9% and 26.6%, respectively. In case of u linolenic acid(C18:3), pumpkin C, B and A showed 22.6%, 23.6% and 44.8%, respectively. In case of palmitoleic acid(Cl6:1), pumpkin C. B and A showed 12.4%, 10.1% and 0.5%, respectively. In case of oleic acid(C18:1), pumpkin C. B and A showed 9.2%, 7.7% and 2.8%, respectively, In case of stearic acid(C18:0), pumpkin C, B and A showed B.S%, 3.7% and 3.5%, respectively. The ratio of P/S was 1.4, 1.6 and 1.9 for sample C, B and A, respectively. The ratio of w-3/w-6 was 1.1, 0.9 and 2.6 for sample C, B and A, respectively. Through this study, the ripe pumpkin(sample A) was thought to be good enough in nutritional aspects of fatty acids, particularly a-linoleic acid, Cl8 : 3(u-3) series.
