Effects of dietary carotenoids were investigated on the metaboβsm and body pigmentation of rainbow trout(Salmo gairdneri), masu salmon(Oncorhynchus macrostomos), eel(Anguilla japonica), rock fish(Sebastes inermis) and black rock fish(Sebastes schlegeli). Three weeks later after depletion, these fishes were fed diet supplemented with ${\beta}-carotene$, lutein, canthaxanthin', astaxanthin or ${\beta}-apo-8'-carotenal$ for 4 to 5 weeks, respectively. Carotenoids distributed to and changed in integument were analyzed. In the integument of rainbow trout. zeaxanthin, ${\beta}-carotene$ and canthaxanthin were found to be the major carotenoids, while lutein, isocryptoxanthin and salmoxanthin were the minor carotenoids. In the integument of masu salmon, zeaxanthin was found to be the major carotenoids, while triol, lutein, tunaxanthin, ${\beta}-carotene$, ${\beta}-cryptoxanthin$ and canthaxanthin were the minor carotenoids. In the integument of eel, ${\beta}-carotene$ was found to be the major carotenoids, while lutein, zeaxanthin and ${\beta}-cryptoxanthin$ were the minor carotenoids. In the integument of rock fish, zeaxanthin, ${\beta}-carotene$, tunaxanthin$(A{\sim}C)$ and lutein were found to be the major carotenoids, while ${\beta}-cryptoxanthin$, ${\alpha}-cryptoxanthin$ and astaxanthin were the minor carotenoids. Likely in the integument of black rock fish, ${\beta}-carotene$, astaxanthin and zeaxanthin were found to be the major carotenoids, whereas ${\alpha}-cryptoxanthin$, ${\beta}-cryptoxanthin$, lutein and canthaxanthin were the minor contributor. The efficacy of body pigmentation by the accumulation of carotenoids in the integument of rainbow trout and masu salmon were the most effectively shown in the canthaxanthin group and of eel, rock fish and black rock fish were the most effectively shown in the lutein group. Based on these results in the integument of each fish, dietary carotenoids were presumably biotransformed via oxidative and reductive pathways. In the rainbow trout, ${\beta}-carotene$ was oxidized to astaxanthin via successively isocryptoxanthin, echinenone and canthaxanthin. Lutein was oxidized to canthaxanthin. Canthaxanthin was reduced to ${\beta}-carotene$ via isozeaxanthin, and astaxanthin was reduced to zeaxanthin via triol. In the masu salmon, ${\beta}-carotene$ was oxidized to zeaxanthin. Lutein was reduced to zeaxanthin via tunaxanthin. Canthaxanthin was reduced to zeaxanthin via ${\beta}-carotene$. and astaxanthin was reduced to zeaxanthin via triol. In the eel, ${\beta}-carotene$ and lutein were directly deposited but canthaxanthin was reduced to ${\beta}-carotene$, and cholesterol lowering effect by Meju supplementation might be resulted from the modulation of fecal axanthin, astaxanthin and ${\beta}-apo-8'-carotenal$ were oxidized and reduced to tunaxanthin via zeaxanthin. In the black roch fish, ${\beta}-carotene$ was oxidized to ${\beta}-cryptoxanthin$. Lutein was reduced to ${\beta}-carotene$ via ${\alpha}-cryptoxanthin$. Canthaxanthin was reduced to ${\alpha}-cryptoxanthin$ via successively ${\beta}-cryptoxanthin$ and zeaxanthin. Astaxanthin converted to tunaxanthin via isocryptoxanthin and zeaxanthin, and ${\beta}-apo-8'-carotenal$ was reduced to ${\alpha}-cryptoxanthin$ via ${\beta}-cryptoxanthin$ and zeaxanthin.

Carotenoids in integument of wild manchurian trout, Brachymystax lenok, and wild and cultured masu salmon Oncohynchus macrostomus, which are all the Korean native cold fresh water fish, were investigated by thin layer chromatography, column chromatography and HPLC. The total carotenoid contents of the wild manchurian trout were $3.72\;mg\%$ which is relatively higher compare to other species of salmonidae. The carotenoids were composed of $36.9\%$ zeaxanthin and $14.7\%$ $\beta-carotene$ as the major compounds, $7.8\%$ triol $7.3\%$ isocryptoxanthin, $5.7\%$ 4-hydroxy echinenone, $4.7\%$ lutein, $4.5\%$ salmoxanthin and $2.2\%$ astaxanthin as minor compounds, and other carotenoids such as canthaxanthin, tunaxanthin A, tunaxanthin B, tunaxanthin C, $\beta-cryptoxanthin$ and $\alpha-cryptoxanthin$ as minute carotenoids. Wild masu salmon contained more total carotenoids than cultured one and the contents were $0.82\;mg\%$ and $0.66\;mg\%$, respectively. The composition of the carotenoids from wild masu salmon were $20.7\%$ xeaxanthin, $17.0\%$ isocryptoxanthin and $15.8\%\;\beta-carotene$ as major compounds, and $6.2\%$ triol, $6.1\%$ 4-hydroxy echinenone, $6.1\%$ salmoxanthin, $5.9\%$ canthaxanthin, $5.8\%$ lutein, $4.9\%$ $\alpha-cryptoxanthin$ and $1.0\%$ astaxanthin as minor compounds. The composition of the carotenoids from cultured masu salmon were $19.7\%$ isocryptoxanthin, $18.0\%$ $\beta-carotene$ and $10.3\%$ zeaxanthin as the major compounds, and $8.9\%\;\beta-cryptoxanthin$, $8.5\%\;\alpha-cryptoxanthin$, $8.0\%$ lutein, $7.6\%$ canthaxanthin, $5.1\%$ triol and $2.0\%$ astaxanthin as minor carotenoids. Based on these data, wild masu salmon contained more zeaxanthin, salmoxanthin and 4-hydroxy echinenone while cultured masu salmon contained more $\alpha-cryptoxanthin$, indicating that carotenoid pigment of masu salmon depends on their living conditions. Unlike wild masu salmon, 4-hydroxy echinenone and salmoxanthin which are the characteristic carotenoids of salmons, were not found in the integument of cultured masu salmon. Unlike manchurian trout, both wild and cultured masu salmon did not contain tunaxanthin A, tunaxanthin B and tunaxanthin C.

The spontaneous frequency of genetic damage and the possible relationship of this damage to total radical-trapping antioxidant potential(TRAP) and antioxidant vitamins, including plasma levels of $\alpha$-carotene, $\beta$-carotene, cryptoxanthin, retinol, $\alpha$-tocopherol and ${\gamma}$-tocopherol in humans were investigated in 57 subjects using two indices of genetic damage, SCE & HFC frequency. The mean of SCE and HFC frequencies were weakly correlated with plasma TRAP(r=-0.305, p<0.1 for SCEs: r=-0.297, p<0.1 for HFCs, respectively), but those were strongly negatively correlated with plasma $\beta$-carotence(r=-0.385, p<0.01 for SCEs : r=-0.392, p<0.01 for HFCs) and cryptoxanthin(r=-0.312, p<0.05 for SCEs : r=0.335, p<0.05 for HFCs, respectively) levels in the subjects. However, those DNA damage markers including SCE and HFC did not correlate with either plasma $\alpha$-carotene, $\alpha$-tocopherol or retinol concentrations. The mean of SCE and HFC frequencies were positively correlated with plasma ${\gamma}$-tocopherol level(r=0.421, p<0.01 for SCEs : r=0.399, p<0.01 for HFCs, respectively). These findings indicate that increased cytogenetic DNA changes, as determined by SCE and HFC frequencies are possibly associated with generation of free radicals in lymphocytes and decreased plasma antioxidant vitamin($\beta$-carotene and cryptoxanthin) status in the subjects.

Five hundred and seventy-eight healthy subjects (351 men and 227 women) with a mean age of 44.8 years (45.2 for men, 44.3 for women) participated in this study. The serum concentrations of $\alpha$-tocopherol, \beta$-carotene, $\alpha$-carotene, zeaxanthin + lutein, cryptoxanthin, lycopene and retinol of normal Koreans were measured, and their relation to gender, age, BMI, alcohol consumption, cigarette smoking, and menopausal status were evaluated. The concentrations of $\alpha$-tocopherol, carotenoids and retinol in serum were measured simultaneously by reverse phase HPLC (multi-wavelength, gradient and computerized automatic system). Average serum levels of $\alpha$-tocopherol, \beta$-carotene and retinol were 10.1$\pm$0.41\mu$g/dl, 33.1$\pm$1.24\mu$g/dl, and 82.0$\pm$1.63\mu$g/dl for men and 11.1$\pm$0.74\mu$g/ml, 48.1$\pm$1.60\mu$g/dl and 64.5$\pm$1.96\mu$g/dl for women, respectively, Serum concentrations of $\alpha$-tocopheol \beta$-carotene, $\alpha$-carotene, cryptoxanthin and lycopene appeared to be higher in women than in men. The serum concentrations of zeaxanthin + lutein increased with the increase in age of men and those of $\alpha$-carotene and \beta$-carotene increased with the increase in age of women. For men, current smokers showed significantly lower serum concentrations of \beta$-carotene and $\alpha$-carotene than ex-smokers (p <0.05) . Current drinkers also showed significantly lower serum \beta$-carotene and zeaxanthin + lutein concentrations than ex-drinkers. For women, current smokers showed significantly love. serum concentrations of zeaxanthin+lutein and cryptoxanthin than ex-smokes (p<0.05). Men with BMI$\geq$24 showed significantly lower serum concentrations of \beta$-carotene, $\alpha$-carotene, lycopene and cryptoxanthin than men with BMI < 20. The mean concentrations of $\alpha$-tocopherol, \beta$-carotene, $\alpha$-carotene and lycopene far postmenopausal women were higher than those for premenopausal women (p<0.05). In conclusion, there were obvious differences in serum $\alpha$-tocopherol and carotenoids levels depending on gender, age, cigarette-smoking habits, alcohol consumption, BMI and menopausal status. further studies are required to establish the normal levels of these vitamins for children and the elderly and to elucidate their roles in different disease states.

The serum levels of antioxidant materials (${\alpha}$-carotene, ${\beta}$-carotene, ${\beta}$-cryptoxanthin, lutein, lycopene, ${\alpha}$-tocopherol, ${\gamma}$-tocopherol, retinol) of the healthy Korean middle-aged adults (n = 373) were measured and their relationships with the serum lipids and anthropometric indices were analyzed. The serum levels of ${\beta}$-cryptoxanthin, ${\beta}$-carotene, lutein were higher than those of lycopene and ${\alpha}$-carotene. The levels of all measured carotenoids except lutein were significantly higher in females than in males, but retinol level was vice versa. There was a tendency of increase in serum levels of antioxidant vitamins with increasing age. The serum carotenoid levels had a positive correlation with serum cholesterol and a negative correlation with serum triglyceride. The serum levels of tocopherols or retinol showed a significantly positive relationship with blood cholesterol or triglyceride. In overall, anthropometric indices showed negative relations with serum carotenoids levels, but vice versa with serum tocopherol or retinol levels. Particularly, ${\beta}$-carotene and lutein levels showed a significantly negative relation with blood pressure in male subjects. The serum levels of ${\alpha}$-carotene, ${\beta}$-carotene and ${\beta}$-cryptoxanthin had significantly negative relations with body fat-related indices in female subjects. The results demonstrated that blood antioxidants levels differed by sex and age, and had significant relations with blood lipid levels and anthropometric indices. Therefore, the rationale and significance of the relationships need to be elucidated in the future study related to dietary intakes and life style.

Difference of carotenoid pigments in integuments of the wild and cultured flounder, Paralichthys olivaceus and yellowtail, Seriola quinqueradiata were studied. Total carotenoid contents in integuments of the wild and cultured flounder were 1.38mg% and 1.l6mg%, respectively. The main carotenoids in integuments of the wild flonder were zeaxanthin (19.22%), $\beta$-carotene type triol (17.80%), tunaxanthin C (17.77％), lutein (16.44%) and tunaxanthin B (13.70%). In addition, tunaxanthin A (5.42%), $\alpha$-cryptoxanthin (4.80%), astaxanthin (0.69%) and $\beta$-cryptoxanthin (0.24%) were also contained in small amounts. But in the cultured flounder, lutein (38.21%) and zeaxanthin (29.69%) were contained as main carotenoids. In addition, $\beta$-carotene type triol (7.80%), tunaxanthin C (7.05%), $\alpha$-cryptoxanthin (4.34%), tunaxanthin B (4.21%), as-taxanthin (2.40%) and $\beta$-cryptoxanthin (1.30%) were present in small amounts. Consequently, the wild flounder contained higher amounts of tunaxanthin and trios but contained lower amounts of lutein and zeaxanthin than the cultured flonder. The contents of carotenoids from integuments of wild and cultured yellow-tail were 1.08mg% and 0.09mg%. Wild and cultured yellowtail have similar carotenoid patterns, consisting of tunaxanthin C (44.11%, 43.37％), tunaxanthin B (33.56%, 29.23%) and tunaxanthin A (18.22%, 21.68%), respectively.

The present study was performed to elucidate desmutagenic principles from Ecklonia stolonifera extracts against 2-amino-1-methyl-6-phenylimidazo[4,5-b] pyridine(PhIP) and 2-amino-3,8-dime-thylimidazo[4,5-f]duinoxaline(MeIQx) with Salmonella/mammalian-microsome mutagenicity test. Alginate, phenols, chlorophyll and carotenoids from Ecklonia stolonifera were extracted and their desmutagenicities were assayed. Alginate hydroysates showed desmutagenic activities against PhIP and MeIQx at high level dose. Phenol fractions and bromophenol showed desmutagenic activity of about MeIQx at high level dose. Phenol fractions and bromophenol showed desmutagenic activity of about 90% per 0.5mg against PhIP and MeIQx. Chlorophyllin among chlorophyll derivatives exhibited remarkable desmutagenic activities of 92.9% and 82.7% at 20uM against PhIP and MeIQx, respectively. Carotenoids, such as lutein and $\alpha$-cryptoxanthin isolated from Ecklonia stolonifera exerted also high desmutagenic activity. Major desmutagenic substances from Ecklonia stolonifera are considered to be chlorophyllin, phenols, lutein, $\alpha$-cryptoxanthin and low molecular alginates.

The effects of smoking and physical exercise on the plasma concentrations of lipid-soluble antioxidants were investigated in 62 healthy males, aged 34-65 years. Current smokers (n=21) and ex-smokers(n=16) had significantly lower plasma levels of carotenoids ($\alpha$-carotene, $\beta$-carotene, cryptoxanthin and lycopene), $\alpha$-tocopherol and ${\gamma}$-tocopherol than non-smokers (n=25). Plasma concentrations of retionl and ubiquinone (coenzyme Q10) were lower among ex-smokers and current smokers than among non-smokers, but the differences were not statistically significant. Regular physical exercise was associated with increased plasma levels of lipid-soluble antioxidants. Plasma concentrations of crytoxanthin, retinol and ubiquinone were significantly elevated in the group engaging in moderate amounts of exercise (more than 20 minutes per day) compared to the group engaging in small amounts of exercise (less than 10 minutes per day). Plasma $\alpha$-carotene, $\beta$-carotene, lycopene levels in the subjects were affected more by smoking than by exercise. However, plasma levels of cryptoxanthin, retinol and ubiquinone in the subjects were affected more by exercise than by smoking. These findings suggest than smoking may cause a decrease in plasma lipid-soluble antioxidants during neutralization of reactive oxygen species present in cigarette smoke and that poor exercise habits may accelerate this imbalance of oxidant/antioxidant homeostasis in middle-aged Korean men.

This study was performed as a part of comparative biochemical studies of carotenoid pigment for the fresh water fish. Carotenoids in integument of Korean dark sleeper, Odontobutis platycephala, and dark sleeper, Odontobutis odontobutis interrupta, which are all the Korean native fresh water fish, were separated by thin layer chromatography, column chromatography and HPLC. The separated carotenoid were then reduced and isomerized by NaBH4 and I2 respectively to investigate UV-Vis spectrophotometeric patterns and chracterized by IR, 1H-NMR and Mass spectrum. The content of total carotenoids in the integument of Korean dark sleeper was 3.01mg% in April, but it was increased to 3.74mg% in September at the near of spawning period. The carotenoid isolated in April consisted of $\beta$-carotene(25.6%), lutein(18.5%) and zeaxanthin(12.0%) as major carotenoids and also contained isocryptoxanthin, diatoxanthin, tunaxanthin, cynthiaxanthin, canthaxanthin and $\alpha$-cryptoxanthin as minor carotenoids. Similarly, in September the carotenoid consisted of $\beta$-carotene(16.5%), zeaxanthin(13.7%) and cynthiaxanthin(13.6%) as major carotenoids and also contained lutein, isocryptoxanthin, tunaxanthin, $\alpha$-cryptoxanthin, diatoxanthin and canthaxanthin as minor carotenoids. At the near of spawning period, the content of cynthiaxanthin and $\alpha$-cryptoxanthin were increased. The content of total carotenoids in the integument of spawning period. T도 carotenoid isolated in April and September consisted of $\beta$-carotene(24.9%, 27.5%), zeaxanthin(14.4%, 20.9%) and lutein(12.6%, 11.4%) as major carotenoids and also contained cynthiaxanthin, tunaxanthin, diatoxanthin, isocryptoxanthin, $\alpha$-cryp-toxanthin and canthaxanthin as minor carotenoids. At the near of spawning period, the content of zeaxanthin was increased, indicating that the carotenoid composition were dependent upon their living conditions and their integument colors. Both Korean dark sleeper and dark sleeper contained high amount of cynthiaxanthin and diatoxanthin which are found as rare carotenoids in the other of fresh water fish. It is interes that they also contained tunaxanthin which is a specific carotenoid in marine fishes.
