Mucoceles of the minor salivary glands are the most common cystic lesions affected the oral mucosa. They are believed to be the result of trauma to the salivary duct caused, for example, by biting the lip, cheek, or tongue. Surgical excision has been the most common treatment for these lesions, but occasional recurrences develop after excision because surgical trauma may damage the surrounding minor salivary glands Although various alternative nonsurgical approaches, such as steroid infection, application of gamma-linolenic acid, have also been reported, they are not used routinely, Lasers, particularly the carbon dioxide laser, have been used in the management of mucoceles. Although this treatment requires specialized equipment. Cryotherapy is another effective nonsurgical method for treating mucoceles. Clinically, cryotherapy has primarily been applied to the treatment of leukoplakia and hyperplastic, granulomatous, vascular, and pigmented lesions. Limited information, however, is available on the application of cryotherapy in salivary gland lesions, including mucoceles. A simple and easy cryotherapy to treat a mucocele on the lower lip is described. A 25 years old female patient with a mucocele on the lower lip was treated by direct application of liquid nitrogen with a cotton swab. The lesion was exposed to 4 or 5 cycles composed of freezings of 10-30 s and thawings of double the freezing times. No anesthesia was required. The lesion nearly disappeared without scar 10 days after the cryotherapy. Cryotherapy has become an established nonsurgical method, characterized by its simple application, therapeutic effectiveness, painless during the procedure and low incidence of secondary infection and hemorrhage.

This study investigated lipid profiles and antioxidant capacities of seven Korean rapeseed cultivars (Naehan, Tamla, Mokpo111, Yeongsan, Tammi, Hanla, and Mokpo68). The rapeseeds contained 29.3~33.2% of extracted lipid and major fatty acids were oleic, linoleic, and linolenic acids. The ratio of omega-6/omega-3 fatty acids was 2.20~3.68 with the highest in Hanla and lowest in Naehan. Glycolipid ranged from 0.21 g/100 g to 0.47 g/100 g. Phospholipid content was 0.55~1.15 g/100 g with the highest in Tammi and the lowest in Mokpo68, and the most common phospholipid was phosphatidylcholine. Tocopherol content was 9.45~15.11 mg/100 g in the order of ${\gamma}$ > ${\alpha}$ > ${\beta}$ > ${\delta}$-tocopherol, and Naehan contained the highest amount of tocopherols (P<0.05). Total phenol content (TPC) of rapeseed was 314.64~577.08 mg SAE/100 g. Tamla contained the highest TPC, and showed the highest antioxidant activity determined by 1,1-diphenyl-2-picrylhydrazyl free radical scavenging capacity and ferric reducing antioxidant power.

To characterize phytonutrients, the seeds of 12 purple Perilla (Perilla frutescens var. crispa) accessions collected from Korea and Japan were used for quantitative analysis of tocopherols, phytosterols, squalene and fatty acids. The average tocopherol, squalene and phytosterols contents were 12.2 mg $100g^{-1}$, 3.99 mg $100g^{-1}$ and 77.20 mg $100g^{-1}$, respectively. Among 4 tocopherol (T) isomers (${\alpha}$-T, ${\beta}$-T, ${\gamma}$-T, and ${\delta}$-T), ${\gamma}$-T was present in the highest quantity (11.03 mg $100g^{-1}$) with the least variation (CV = 13.7%), while ${\beta}$-T was present in lowest quantity (0.25 mg 1$100g^{-1}$). Compared to campesterol (4.36 mg $100g^{-1}$) and stigmasterol (13.32 mg $100g^{-1}$), ${\beta}$-sitosterol exhibited higher quantity (59.51 mg $100g^{-1}$) with 9.5% of variation. The major fatty acids were unsaturated fatty acids such as linolenic (61.5%), linoleic (17.3%), and oleic (9.9%) acids compared to saturated ones: palmitic (7.6%) and stearic (3.7%) acids. When Korean and Japanese accession were compared, almost no difference in content could be observed, while more variation as evaluated by CV (%) could be observed in Japanese accession in most phytonutrients suggesting wider genetic variation of purple Perilla in Japan. Presence of all above-mentioned phytonutrient compounds strongly suggested health beneficial value of purple Perilla seeds.

This experiment was carried out to evaluate performance and carcass characteristics of 40 crossbred young bulls ($Zebu{\times}European$) finished in a feedlot under two roughage sources (Bermuda grass hay or sorghum silage) with or without the addition of yeast (Saccharomyces cerevisae). The bulls were 20 months old, their initial average weight was 356 kg and they were allocated into four groups of ten animals. The experimental diets were Bermuda grass, Bermuda grass+yeast, sorghum silage and sorghum silage +yeast. Animal performance and carcass characteristics were not influenced by roughage source or yeast addition. The average daily weight gain was 1.50 kg, dry matter intake (DMI) was 11.1 kg/d, DMI as percentage of liveweight was 2.60% and feed dry matter conversion was 7.70. The mean dressing percentage was 52.0% and hot carcass weight was 268 kg. Carcass conformation was classified between good-minus to good. Carcass length (137 cm), leg length (72.9 cm) and cushion thickness (26.6 cm) were not influenced by treatments. The average fat thickness was 3.80 mm and the Longissimus muscle area was 66.9 $cm^{2}$. The classification of color, texture and marbling were slightly dark red to red, fine and slight-minus to light-typical, respectively. The mean percentage of bone, muscle and fat in the carcass was 15.5%, 62.3% and 22.5%, respectively. Yeast addition increased ${\gamma}$-linolenic fatty acid (0.15 vs. 0.11%) deposition. Bermuda grass hay increased deposition of ${\alpha}$-linolenic (0.49 vs. 0.41%), arachidonic (2.30 vs. 1.57%), eicosapentaenoic (0.41 vs. 0.29%), docosapentaenoic (0.80 vs. 0.62%), docosahexaenoic (0.11 vs. 0.06%) and n-3 fatty acids, and reduced n-6: n-3 ratio in meat, when compared to sorghum silage treatments. The treatments had no effect on saturated fatty acids (49.5%), polyunsaturated fatty acids (11.8%), n-6 fatty acids (9.87%), n-3 (1.61%) and PUFA:SFA ratio (0.24). Monounsaturated fatty acid levels were higher on sorghum silage (40.7 vs. 37.7%). The addition of yeast caused higher n-6: n-3 ratio (7.28 vs. 5.70) than treatments without yeast.

Nutritional compositions, volatile compounds, and sensory attributes of Cynanchi wilfordii Radix were analyzed in order to examine its practical utilization as a food resource. In the proximate analysis, protein and lipid contents were shown to be 14.6 and 5.0 mg/100 g, respectively, in C. wilfordii Radix. Potassium was the most predominant mineral (809 mg/100 g), as determined by inductively coupled plasma-optical emission spectrometry in parallel with microwave acid digestion. Total phenolic content was found to be 410 mg/100 g. Further, arginine and linoleic acid were the most abundant amino acid and fatty acid of C. wilfordii Radix, respectively. To examine its functional properties, classical 2,2-diphenyl-1-picrylhydrazyl (DPPH) analysis was performed. As a result, the concentration of C. wilfordii Radix required to scavenge 50% of DPPH radicals was 1.16 mg of dried material. Lastly, in olfactory and sensory tests, ${\beta}$-eudesmol (woody odor) was the major flavor compound responsible for the bitter taste and sensory attributes of C. wilfordii Radix. Taken altogether, the above results provide important preliminary results for utilization of C. wilfordii Radix as a food resource.

This study investigated the changes in the nutraceutical lipid components of brown rice oil after germination. Four different high-yielding cultivars (Dasan1, Segyejinmi, Hanareum1 and Hanareum2) of Korean brown rice were selected and brown rice oil was extracted from each cultivar before and after germination. Free fatty acid, squalene, policosanols, and isomers of phytosterol were analyzed using GC, and isomers of tocols (tocopherol and tocotrienol) and ${\gamma}$-oryzanol were quantified using HPLC from both brown rice oil (BRO) and germinated brown rice oil (GBRO). The contents of phytosterol isomers, campesterol, stigmasterol, and ${\beta}$-sitosterol were increased by 8.3%, 31.6%, 3.3% in GBRO, respectively. Furthermore, the squalene content showed the highest increase of up to 2.4 fold in GBRO compared to BRO. In addition, linoleic and linolenic acid composition increased whereas oleic and palmitic acid decreased in the GRBO. However, the contents of tocols (tocopherol and tocotrienol) in GBRO were lower than those in BRO, and there was no significant difference in policosanol and ${\gamma}$-oryzanol between GBRO and BRO. These results suggest that GBRO has the potential as a healthy and functional source due to its lipid profile on improved lipid metabolism.

Asterias amurensis (starfish) is a marine organism that is harmful to the fishing industry, but is also a potential source of functional materials. The present study was conducted to analyze the profiles of fatty acids extracted from A. amurensis tissues and their anti-inflammatory effects on RAW264.7 macrophage cells. In different tissues, the component ratios of saturated fatty acids, monounsaturated fatty acids, and polyunsaturated fatty acids differed; particularly, polyunsaturated fatty acids such as dihomo-gamma-linolenic acid (20:3n-6) and eicosapentaenoic acid (20:5n-3) were considerably different. In lipopolysaccharide-stimulated RAW264.7 cells, fatty acids from A. amurensis skin, gonads, and digestive glands exhibited anti-inflammatory activities by reducing nitric oxide production and inducing nitric oxide synthase gene expression. Asterias amurensis fatty acids effectively suppressed the expression of inflammatory cytokines such as tumor necrosis $factor-{\alpha}$, interleukin-$1{\beta}$, and interleukin-6 in lipopolysaccharide-stimulated cells. Cyclooxygenase-2 and prostaglandin $E_2$, which are critical inflammation biomarkers, were also significantly suppressed. Furthermore, A. amurensis fatty acids reduced the phosphorylation of nuclear $factor-{\kappa}B$ p-65, p38, extracellular signal-related kinase 1/2, and c-Jun N-terminal kinase, indicating that these fatty acids ameliorated inflammation through the nuclear $factor-{\kappa}B$ and mitogen-activated protein kinase pathways. These results provide insight into the anti-inflammatory mechanism of A. amurensis fatty acids on immune cells and suggest that the species is a potential source of anti-inflammatory molecules.

This study was carried out to elucidate the effect of different rearing system on cortisol level, stress hormone, and fatty acid composition in the edible muscle tissues. These steers were reared in two different systems including antibiotic-free (ARS) and conservative system (CRS). In the M-Longissimus tissue, cortisol level was significantly lower in ARS than CRS, (p=0.0176). But, the levels of total saturated and unsaturated-fatty acids does not differ in ARS as CRS (p >0.05). However, the total saturated fatty acid levels tended to be greater in CRS and the total unsaturated fatty acid levels tended to be greater in ARS. However, the level of n-6 unsaturated fatty acid was higher in ARS than CRS (p=0.004). Especially, levels of linoleic acid (LA) and ${\gamma}$-linolenic acid (GLA) were significantly higher in ARS (p <0.01). Cortisol level and the n-6 fatty acid content in muscle tissue were negatively correlated (at p=0.00140.) In conclusion, ARS may produce beef with higher quality which contains lower cortisol and greater n-6 fatty acids, such as ALA and GLA.

The fatty acid composition, selected minor components, and the oxidative stability of the mixed edible oil (perilla seed oil and rice bran oil, 3:7 (v/v)) were analyzed. The fatty acid composition of the mixed oil was 32.1% of oleic acid, 30.6% of linoleic acid, 21.4% of linolenic acid, 13.0% of palmitic acid, and 1.7% of stearic acid. The mixed oil contained ${\alpha}$, ${\gamma}$ and ${\delta}$-tocopherols and tocotrienols showing the highest contents of ${\alpha}$-tocopherol. Total amount of tocopherols contained in the mixed oil was 46.63 mg/100 g oil. The composition and content of phytosterols were determined by a GC equipped with a flame ionization detector. Total quantity of phytosterols in the mixed oil was 712.80 mg/100 g oil. The most predominant phytosterol in the mixed oil was ${\beta}$-sitosterol, followed by campesterol and stigmasterol, in a decreasing order. The oxidative stability of the mixed oil was much higher than that of perilla oil, and similar to that of soybean oil, indicating the high oxidative stability of the mixed oil.

Atopic dermatitis (AD) is characterized by chronic relapsing inflammation and is associated with hyper-production of immunoglobulin E (IgE). Recent studies have suggested that one of the treatments to alleviate symptoms of AD could be a supplementation of probiotics, Lactobacillus, Rhamnosus, Bifidus, etc. The purpose of this study was to evaluate the effects of probiotics on immune parameters in NC/Nga mice treated with 1-chloro-2,4-dinitro-benzene (DNCB). To induce atopic dermatitis, DNCB was treated to the back of mice for 2 weeks. Then, NC/Nga mice were divided into the four experimental groups randomly. Probiotics fragment, probiotics with other complex (Lactobacillus rhamnosus GG, Bifidobacterium lactis Bb-12LbL, L. plantarum K8, L. plantarum K8 fragment, ${\gamma}$-linolenic acid), antihistamine, and distilled water were administrated orally to the NC/Nga mouse for 4 weeks of experimental period. The groups were probiotics fragment group (DPF), probiotics with other complex group (DPOC), antihistamine group (DAH) and distilled water group (DDW) as a control group. The levels of serum IgE, interlukin-4 (IL-4), interlukin-5 (IL-5), interferon-gamma (IFN-${\gamma}$) and spleenocyte IgE were measured. The levels of serum IgE were significantly different among the four experimental groups. Before the treatment, there was no differences among the groups. However, from the first through the third week of the treatments, the levels of serum IgE in the probiotics (DPF, DPOC) and antihistamine (DAH) groups were lower than those of control group (p < 0.05). The levels of serum IL-4 of DPOC group was significantly lower than that of control group (p < 0.05) and serum IL-5 levels of DPF, DPOC, and DAH groups were significantly lower than that of control group. The levels of serum IFN-${\gamma}$ were not different among the four experimental groups. The levels of serum IgE in supernatant of spleen lymphocytes were not significantly different among the groups. These results suggest that probiotics supplementation showed partial effectiveness in the DNCB treated NC/Nga mice via modulation of IgE level and IL-4, IL-5 production. Based on these findings, probiotics exhibited the inhibitory effect via IL-4 production thereby inhibited the production of IgE in atopic animal model NC/Nga mice.
