The anti-inflammatory effect of tuna heart water extract (THWE) was investigated using lipopolysaccharide-induced inflammatory response in this study. Anti-inflammatory effect was detected by the cell proliferation and the production levels of nitric oxide, pro-inflammatory cytokines such as interleukin-6 (IL-6), IL-$1{\beta}$, and tumor necrosis factor-alpha. As a result, there were no cytotoxic effects on proliferation of macrophages treated with THWE compared to the control. The production of pro-inflammatory cytokines was remarkably suppressed compared with that of the LPS only group. These results suggest that THWE exerts the anti-inflammatory property by inhibiting production of inflammatory factors and may be a potential material for anti-inflammatory therapy.

Atopic dermatitis (AD) is a form of allergic skin inflammatory characterized by late eczematous skin lesions. The incidence of AD is increasing, and it causes problems with administrative costs. Therefore, development of an AD treatment with no side effects is needed. The purpose of this study was to evaluate tuna heart ethanol extract (THEE), a functional extract from by-product of tuna. AD was induced by spreading 2,4-dinitrochlorobenzene (DNCB) on the backside of BALB/c mice. The effect of THEE was tested by measuring skin clinical severity score, secretion of cytokines and IgE, and proliferation. Secretion of $TNF-{\alpha}$, IL-4, IL-5, IL-13, and IgE significantly decreased in a THEE-independent manner. In contrast, levels of IL-10 and $IFN-{\gamma}$ significantly increased in mice sera and splenocytes. In addition, THEE alleviated AD symptoms compared to the DNCB only group. In conclusion, these results demonstrate that THEE has an inhibitory effect on AD and may be a useful substance for the development of cosmeceuticals.

This study intended to compare the hypolipidemic effects among six experimental groups fed by three different dietary carbohydrates on hyperlipodemic rats. Sixty experimental animals were divided into 6 groups, SB, ST, SP and CB, CT, CP after production of hyperlipidemia fed by SB diet on Sprague-Dawley rats for 4 weeks. Rats were fed by six experimental diets for eight weeks. Hyjperlipidemic rats showed three times higher in plasma TG level not in cholesterol content compare to control group fed by stock diet. Two different dietary carbohydrates seem to be effective in body weight gain and fat cumulation as weight of epididymal fat pad. In comparison of S and C groups, C fed groups showed lowering effect in plasma TG and total lipid contents, but among S fed groups, ST and SP group showed lower than SB in this respects. Dietary carbohydrates seem to be more effective than fat in plasma lipid contents. When we compare among three different fat groups, only T groups with different carbohydrates increased in peroxisomal lipid oxidation and decreased in lipogenic enzyme activites. As same token, sucrose fed group with three fat sources seem to increase activiteies enzyme activities. In epididymal fat pad and Heart, SP and CP effect more in LPL activites than other groups. In conclusion, we can recommed to consume polysaccharides rather than disaccharide and n-3 fatty acids such as perilla and tuna oils to alleviate hypertringlycemic condition.

Propofol infusion syndrome characterized by rhabdomyolysis, metabolic acidosis, kidney, and heart failure has been reported in long-term propofol use for sedation. It has been reported that intracellular adenosine triphosphate (ATP) is reduced in rhabdomyolysis. The study aims to investigate the protective effect of ATP against possible skeletal muscle damage of propofol in albino Wistar male rats biochemically and histopathologically. PA-50 (n = 6) and PA-100 (n = 6) groups of animals was injected intraperitoneally to 4 mg/kg ATP. An equal volume (0.5 ml) of distilled water was administered intraperitoneally to the P-50, P-100, and HG groups. One hour after the administration of ATP and distilled water, 50 mg/kg propofol was injected intraperitoneally to the P-50 and PA-50 groups. This procedure was repeated once a day for 30 days. The dose of 100 mg/kg propofol was injected intraperitoneally to the P-100 and PA-100 groups. This procedure was performed three times with an interval of 1 days. Our experimental results showed that propofol increased serum CK, CK-MB, creatinine, BUN, TP I, ALT, AST levels, and muscle tissue MDA levels at 100 mg/kg compared to 50 mg/kg and decreased tGSH levels. At a dose of 100 mg/kg, propofol caused more severe histopathological damage compared to 50 mg/kg. It was found that ATP prevented propofol-induced muscle damage and organ dysfunction at a dose of 50 mg/kg at a higher level compared to 100 mg/kg. ATP may be useful in the treatment of propofol-induced rhabdomyolysis and multiple organ damage.
