This study aimed to investigate the association between interest in beauty care and dietary behaviors of 581 (analysis rate 96.0%) high school girls in Incheon using a survey done in May 2019. Based on the degree of interest in beauty care, subjects were classified as "Beauty care group (n=346)", and "Non-beauty care group (n=235)". The mean age of the subjects was 16.5 years old. The beauty care group had significantly lower BMI than the non-beauty care group (p<0.01). The beauty care group showed a significantly higher interest in weight control than the non-beauty care group (p<0.001). The most time-consuming preschool morning activity in the beauty care group was beauty care, while that of the non-beauty care group was eating breakfast (p<0.001). The beauty care group had significantly higher frequency of exercise than the non-beauty care group (p<0.05). The number of individuals who skipped breakfast was significantly higher in the beauty care group. In addition, the beauty care group had a significantly higher frequency of taking morning snack, convenience food (p<0.01), sweet snacks (p<0.05), and processed beverages (p<0.05) than the non-beauty care group. Our result findings provide important information on the priority groups for nutrition education based on beauty care interest.

These studies were designed to investigate the effects of pine (Pinus densiflora Sieb et Zucc.) needle extract (PNE) on oxygen radicals and their scavenger enzymes in liver membranes of Sprague-Dawley (SD) rats as a study on investigation of anti-aging effect and determination of chemical structures of PNE through the animal experiments. Male SD rats were fed basic diets (control group) and experimental diets (0.5% and 1.0%-PNE group) for 6 weeks. There were no significant differences in hydroxyl radical (·OH) formations of liver mitochondria and microsomes in 0.5%-PNE group, while ·OH formations were significantly decreased (10% and 18%, respectively) in liver mitochondria and microsomes of 1.0%-PNE group compared with control group. Microsomal hydrogen peroxides and cytosolic superoxide radicals were remarkably decreased (20% and 20∼25%, respectively) in 0.5% and 1.0%-PNE groups compared with control group. Mn-SOD activities in mitochondria were significantly increased about 10% in 1.0%-PNE group, while Mn-SOD activities in mocrosomes were remarkably increased (16∼20%) in 0.5% and 1.0%-PNE groups compared with control group. There were no significant differences in Cu, Zn-SOD activities of liver cytosol in 0.5% and 1.0%-PNE groups, while glutathione peroxidase (GSHPx) and catalase (CAT) activities were significantly decreased (28∼30% and 15∼30%, respectively) in liver cytosols of 0.5% and 1.0%-PNE groups compared with control group. These results suggest that these PNE may play a effective role in a attenuating a oxygen radical formations and increasing a scavenger enzyme activities.

Pine(Pinus densiflora Sieb et Zucc.) is one of rhe popular plant drugs which has been used as a medicine in Asia. To investigate the effect of pine needle extract (PNE) on oxygen radicals and their scavenger enzymes in brain membranes of Sprague- Dawley (SD), make SD rats were fed basic diets(control group), and experimental diets (PNE group) with 0.5 and 1.0% of PNE 6 weeks. Mitochondrial hydroxyl radical levels in brain of 0.5%-PNE and 1.0%-PNE groups were significantly inhibited to 30% and 25%, respectively, and microsomal hydrogen peroxide levels in brain of 0.5%-PNE and 1.0%-PNE groups were significantly inhibited to 15% compared with control group. Cytosolic superoxide rdical levels in 1.0%-PNE group were significantly inhibited to 20% compared with control group. Lipid peroxide(LPO) levels in brain mitochondria of 0.5%-PNE and 1.0%-PNE groups were significantly lower(25% and 35%) than that in control group. Mn-superoxide disumtase (SOD) activities in brain of 0.5%-PNE and 1.0%-PNE groups were significantly higher(18% and 12%) than those in control groups, but Cu,Zn-SOD activities in brain of 0.5%-PNE were significantly activated to 15% compared with control group. Glutathione peroxidase(GSHPx) activities in brain of 1.5%-PNE and 1.0% PNE groups were significantly higher(14% and 12%) than those in control group. These results suggest that more beneficial effects such as inhibition of oxygen radicals and lipid peroxide(LPO). and oncreases of scavenger enzymes in brain membranes of SD rats may be effectively modulated by administration of pine needle extract (PNE)

This research is to examine the detoxication effect of methionine on cadmium intoxication For this purpose, this paper provides an analysis of the data on the groups of mice (ICR), one group of mice treated with 40 ppm of cadmium only. and other groups of mice combined-treated with cadmium and 0.1%, 0.25%, 0.5% and 1% methionine. After breeding for 40 days, the data on the growth of mice, changes in activation of alkaline phosphatase in blood, and the cadmium content in the liver and kidney, are analysed. The results were as follows: 1) The growth-rate of mice, in the cadmium only injected group, was declined by 9% in comparison with the control group after 40 days. But the two groups of cadmium with 0.5% and 1% methionine showed the rise of 9% ana 14% respectively above the growth-rate of the control group. The results from the groups of cadmium with 0.1% and 0.25%, methionine were similar to that from the cadmium only injected group. 3) Changes in activation of alkaline phosphatase in blood decreased to 86.45% in the cadmium only injected group behind the 100% activation of the control group. The groups of cadmium with 0.1% and 0.25% methionine showed no difference with the former group. But the groups of cadmium with 0.5% and 1% methionine recovered to the 93.14% and 96.08% of activation respectively. 3) The mean content of cadmium in the liver was $0.028{\pm}0.001{\mu}g/g$ in the control group. The cadmium only injected group showed the mean cadmium content of $2.80{\pm}0.62{\mu}g/g$ in the liver, which was similar to $2.82{\pm}1.03{\mu}g/g$ in the group of cadmium with 0.1% methionine, and $2.56{\pm}0.77{\mu}g/g$ in the group of cadmium with 0.25% methionine. But the groups of cadmium with 0.5% and 1% methionine showed the reduction of cadmium contents in the liver to $1.84{\pm}0.56{\mu}g/g$ and $1.74{\pm}0.35{\mu}g/g$ respectively. In the kidney, the groups of cadmium with 0.1%, 0.25% and 0.5% methionine shelved the similar cadmium content to the group treated with cadmium only. But the group of cadmium with 1% methionine showed a small increase to $4.13{\pm}1.00{\mu}g/g$ in comparison with the group treated with cadmium only. This analysis proves that the mobility and diffusion of cadmium in tile tissues advance faster ill the group treated with cadmium and methionine than in the group treated with cadmium only.

The minimum thickness is $5.51{\pm}1.08mm$ for Group 1, $5.06{\pm}0.40mm$ for Group 2, $4.56{\pm}0.78mm$ for Group3, respectively (p=0.0001). But, the thickness at the level of 5mm above the lingular is $0.78{\pm}0.65mm$ for Group 2, $5.63{\pm}1.28mm$ for Group 1, $5.32{\pm}0.91mm$ for Group 3, respectively. There is no significant difference between these groups(P=0.0510). 2. The horizontal location from the midwaist point to lingular is $0.18{\pm}1.57mm$ for Group 1, $0.69{\pm}1.33mm$ for Group 2, $0.66{\pm}1.66mm$ for Group 3, and there is no significant difference between these groups(p=0.0835). But the vertical location from the midwaist point to lingular is $1.45{\pm}2.64mm$ for Group 1, $0.63{\pm}1.44mm$ for Group 2, $0.34{\pm}1.81mm$ for Group 3, and there is significant difference between these groups(p=0.0030). 3. The horizontal location from the midwaist point to mandibular foramen is $0.29{\pm}1.75mm$ for Group 1, $0.63{\pm}1.44mm$ for Group 2, $0.34{\pm}1.81mm$ for Group 3, and there is no significant difference between these groups(p=0.5403). But the vertical location from the midwaist point to mandibular foramen is $-3.33{\pm}4.43mm$ for Group1, $-4.79{\pm}2.26mm$ for Group 2, $-6.06{\pm}2.99mm$ for Group 3, and there is significant difference between these groups(P=0.0001). 4. The horizontal length from the disto-buccal cusp tip of mandibular second molar to lingula is $30.97{\pm}4.17mm$ for Group 3, $28.29{\pm}2.65mm$ for Group 1, $25.48{\pm}0.77mm$ for Group 2 (p=0.0000), and also vertical length is $7.72{\pm}3.22mm$ for Group 3, $6.38{\pm}1.83mm$ for Group 1, $5.89{\pm}2.30mm$ for Group 2 (P=0.0014). 5. The location of lingular is 0.50 from anterior border of mandibular ramus in all groups, if it assumed the length from anterior border to posterior border is 1. And it is almost 0.33 from the sigmoid notch, if it assumed the length from sigmoid notch to antegonial notch is 1. 6. In Group 1, Antilingular prominence is located on ($1.12{\pm}1.43mm,\;4.01{\pm}2.36mm$) from the midwaist point, and there is no correlation between antilingular prominence and lingular, mandibular foramen.

UV-irradiation is a major factor of photo-aged skin, by which pigmentation, wrinkles and laxity are increased. In addition, the epidermal barrier is disrupted, ultimately causing dryness in photo-aged skin. As an effort to search dietary sources for improving the dryness of UV irradiated skin, the dietary effect of red ginseng based functional foods on the epidermal level of ceramides, a major lipid maintaining epidermal barrier, was determined in this study. Albino hairless mice were fed either a control diet [group UV (UV-irradiated control)] or diets with 0.5% (group M0.5) or 1% (group M1.0) of red ginseng extracts mixed with Torilis fructus and Corni fructus (66.7% red ginseng) in parallel with UV irradiation for 5 wks. A normal control group (group C) was fed a control diet without UV irradiation for 5 wks. The epidermal level of ceramides in group UV was significantly lower than that in group C, in which ceramidase, an enzyme involved in ceramide degradation, was highly expressed. In group M0.5, the epidermal level of ceramide was significantly increased to the level even higher than in group C. In addition, protein expression of serine palmitoyl transferase (SPT), a key enzyme involved in de novo ceramide synthesis, was increased in group M0.5. However the epidermal levels of ceramides as well as of ceramidase protein expression in group M1.0 did not differ from those in group UV. In conclusion, we demonstrate that dietary supplementation of red-ginseng extracts mixed with Torilis fructus and Corni fructus at a level of 0.5% level in diet increased the epidermal level of ceramides coupled with the elevated expression of SPT protein.

Let R be a right near-ring. An R-group of type-5/2 which is a natural generalization of an irreducible (ring) module is introduced in near-rings. An R-group of type-5/2 is an R-group of type-2 and an R-group of type-3 is an R-group of type-5/2. Using it $J_{5/2}$, the Jacobson radical of type-5/2, is introduced in near-rings and it is observed that $J_2(R){\subseteq}J_{5/2}(R){\subseteq}J_3(R)$. It is shown that $J_{5/2}$ is an ideal-hereditary Kurosh-Amitsur radical (KA-radical) in the class of all zero-symmetric near-rings. But $J_{5/2}$ is not a KA-radical in the class of all near-rings. By introducing an R-group of type-(5/2)(0) it is shown that $J_{(5/2)(0)}$, the corresponding Jacobson radical of type-(5/2)(0), is a KA-radical in the class of all near-rings which extends the radical $J_{5/2}$ of zero-symmetric near-rings to the class of all near-rings.

This research objected to the diagnosed patients as acute lymphoblastic leukemia, acute myelogenous leukemia, neuroblastoma, non-Hodgkins lymphoma, Hodgkin's disease, kidney tumor, myelodysplastic syndrom and juvenile chronic leukemia after admission in the 'P' hospital in Pusan from Aug. 1. 1999 to Jan. 31. 2000. The results of this study are summarized as follows. 1. On the specific character between the experimental(exp.) group and the control (con.) group : there were 7 of 4-7 years old patients(the most) in the experimental group(53.8％), 5 of 12 years old or older patients in the control group (38.5％). Patients who experienced operation were 7 in the exp. group(53.8％) and 6 in con. group(46.2％). The largest number of the patients' diagnosis was acute lymphoblastic leukemia by 5 in the exp. group(38.5％) and 4 in the con. group (30.8％). The hardest nausea came on the second day by 5 in the exp. group(38.5％), 9 in the con. group(69.2％). 2. P-score of the nausea vomiting on the number of daily anticancer drug administration : first day, the exp. group got 9.6 and the con. group 17.6(P = 0.03). 2nd day, 10.9 and 19.4(P = 0.00), 3rd day, 10.6 and 18.3(P = 0.00), 4th day 10.0 and 18.0, 5th day 10.9 and 16.8(P = 0.05). The score showed statistically significant difference(P < .05). 3. Oral intake didn't show statistically significant difference between two groups. However the average of Oral intake of the exp. group was continually higher than the con. group except to the first day after administration. In conclusion, nursing intervention and nutrition care are much more needed on the 2-3th day after administration to reduce nausea vomiting, and for remission of nausea and enlarging oral intake it is utilizable to apply the easy, economic Oral Cryotherapy to the young patients who undergo chemotherapy.
