  • This studies were to investigate the effects of low power wavelengths Helium-Neon Infra-Red(He-Ne 1R) laser on the changes of the serum mineral components in burn rats. The thirty Spraque-Dawley adult male rats were assigned to the 5 groups: the experimental groups(3), the bum control group (1) and the control group(1). There was made three degree bum by the 250mW IR on the back of each rats. from 3 days after being burned. the experimental laser groups were irradiated low power wavelengths(292 Hz. 1168Hz, 4672Hz) He-He IR laser far 5 minutes every day during the 7 days. The results were as tallows: 1. There were significantly not changes of the levels of serum sodium between all experimental groups. 2. The concentration of potassium in serum on the treated with 292Hz wavelengths group during 5 minutes were significantly increased ,but with 1168Hz wavelenghths group were decreased to the those of burn group. 3. The concentrations of serum calcium in serum 1168Hz wavelengths laser group on the treated with 5 minutes laser were significantly higher to normal level than those of bum groups. As above results. the changes of the 2 essentials mineral(calcium and potassium) in serum levels on the healing process have meaningful effected with the low power wavelengths role on the treated with He-Ne IR laser.

  • In this study, the anti-oxidative effects and components of sprout serum were investigated. In the buds, high levels of zinc, iron and manganese were analyzed in addition to copper, magnesium, and potassium. The free radical (1,1-diphenyl-2-picrylhydrazyl, DPPH) scavenging activity of sprout serum was evaluated with $IC_{50}$. $IC_{50}$ of sprout serum was $58.0\;mgmL^{-1}$, and that of vitamin C was $3.7\;mgmL^{-1}$. In the test of superoxide scavenging activity of sprout serum, the activity was dependent on the concentration of serum. In this case, the $IC_{50}$ was 2.0 wt%. Cell viability was detected by using the MTT method. Cultured human fibroblast was treated with 15 mM $H_2O_2$ and cell viability was 70% in case of control. However, the effect of treating 0.5% of sprout serum was similar to that of 0.0001% of vitamin C.

  • Brine mineral water (BMW) is groundwater near the deep sea, and the mineral component of the BMW is different from the water of the deep sea because the components of BMW are derived from the unique geographical features surrounding it. Recently, BMW has attracted attention due to the unique health-related minerals it possesses; however, the influence of BMW on physiological function has not yet been determined in domestic animals. Therefore, this experiment investigated the influence of BMW on the growth performance, water intake, blood properties, and immunoglobulin (Ig) levels of serum in growing-finishing pigs. A total of 64 pig barrows (Landrace × Yorkshire × Duroc) with an average initial weight of 40.56 ± 0.17 kg were used in the experiment, and 0%, 2%, 3%, and 5% samples of BMW diluted with freshwater were provided to experimental animals during the 56 days. We found that the gain/feed ratio in the 3% BMW group was significantly higher than that in the 5% BMW group of growing-finishing pigs (p < 0.05). The water intake was significantly increased in the 5% BMW group compared with the other groups (p < 0.05) of growing-finishing pigs. Additionally, the concentrations of red blood cells (RBCs), hemoglobin (HGB), and hematocrit (HCT) were significantly higher in the 3% BMW group than in the control group. The level of high-density lipoprotein cholesterol was higher in the 3% BMW group than in the 5% BMW group (p < 0.05). Furthermore, IgG and IgM levels in the serum were significantly higher in the 2% and 3% BMW groups than in the control group (p < 0.05). These results suggest that a dilution of 3% BMW in the intake water could improve the levels of RBCs and serum Igs in growing-finishing pigs.

  • A serum-free medium that could be used for the large-scale culture of mouse hybridoma to produce monoclonal antibodies was developed. The medium was based on a 1:1 mixture of Iscove's Modified Dulbecco's Medium and Ham's F-12, supplemented with insulin 10$\mu\textrm{g}$/$m\ell$, transferrin 10$\mu\textrm{g}$/$m\ell$, ethanolamine 10$\mu$M and selenium 30nM (designated EBM (enriched basal medium) with the supplements). The effect of various supplements of steroid hormones, vitamins, lipid and mineral salts was investigated and their optimal concentration was determined to replace fetal calf serum (PCS). These components were added respectively and then added by way of two or three combination to discern of which component combination was effective to the culture of hybridoma. As a result, serum-free medium KM3 (EBM with BSA 100$\mu\textrm{g}$/$m\ell$, mineral cocktail and 0.05% PEG) was deter-mined. The hybridoma Alps 25-3 cultured in this medium showed almost the same growth rate as in medium added with 2% fetal bovine serum. However, the antibody concentration from KM3 cultures was 80% of that obtained from culture with FCS. KM3 was also examined for the culture of other mouse hybridomas, KW, A4W & HCGK, and it was confirmed that it could support the growth of these hybridomas and the production of monoclonal antibodies.

  • Vitamin D is an essential component of bone and mineral metabolism; its deficiency causes growth retardation and skeletal deformities in children and osteomalacia and osteoporosis in adults. Hypovitaminosis D (vitamin D insufficiency or deficiency) is observed not only in adults but also in infants, children, and adolescents. Previous studies suggest that sufficient serum vitamin D levels should be maintained in order to enhance normal calcification of the growth plate and bone mineralization. Moreover, emerging evidence supports an association between 25-hydroxyvitamin D (25[OH]D) levels and immune function, respiratory diseases, obesity, metabolic syndrome, insulin resistance, infection, allergy, cancers, and cardiovascular diseases in pediatric and adolescent populations. The risk factors for vitamin D insufficiency or deficiency in the pediatric population are season (winter), insufficient time spent outdoors, ethnicity (non-white), older age, more advanced stage of puberty, obesity, low milk consumption, low socioeconomic status, and female gender. It is recommended that all infants, children, and adolescents have a minimum daily intake of 400 IU ($10{\mu}g$) of vitamin D. Since the vitamin D status of the newborn is highly related to maternal vitamin D levels, optimal vitamin D levels in the mother during pregnancy should be maintained. In conclusion, given the important role of vitamin D in childhood health, more time spent in outdoor activity (for sunlight exposure) and vitamin D supplementation may be necessary for optimal health in infants, children, and adolescents.

  • Chitosan is known to have antibacterial, antitumorogenic, hypolipidemic and immunopotentiating activities, hence finding diverse uses as a component in varying functional foodstuffs. However, some investigators reported it caused mineral absoiption inhibition and excess coagulation. From the chemical viewpoint, conventional chitosans are high-molecule polymers lacking water solubility, which could be related with their possible toxicity. A newly developed low- molecule water soluble chitosan is thought to have low toxicity compared to conventional chitosans. But no investigation was carried out to evaluate its toxicity. In this study, a 28-day subacute oral toxicity study of the water-soluble chitosan was performed in Sprague-Dawley rats of both sexes. Each 36 male and female rats were orally administered with 500, 1,000 and 2,000 mg/kg/day for 28 consecutive days, respectively. Clinical parameters (growth rate, feed and water consumption, daily inspection, urine analysis) during the 28 days indicated the water-soluble chitosan did not induce any abnonnal changes. There were no abnormal findings due to the administration of the test substance in gross and microscopic findings. We had not found alteration in absolute and relative organ weight between the control and treated groups, with only exception in the liver but lacking dose-dependency. The results of hematology and serum biochemistry examination revealed that no treatment related changes were between control and all dose groups. In conclusion, it was suggested that subacute toxicity of the water-soluble chitosan was low and the no-observed adverse effect level was considered to be over 2,000 mg/kg in rats.

  • Atopic dermatitis (AD) is a chronically relapsing inflammatory skin disease that often has asthma and allergic rhinitis. Magnesium salts, the important component of minerals in Dead Sea water, are known to exhibit beneficial effects in inflammatory disease. Favorable effects of magnesium ions and sea water treated to the skin of patients with contact dermatitis have been reported. But histological and immunological investigations are insufficient. This study was performed to examine the inhibitory effect of magnesium-rich sea mineral water on the development of AD-like skin lesions in hairless mice. AD-like skin lesions are induced by the repeated application of 2,4-dinitrochlorobenzene (DNCB). Local application of magnesium-rich sea mineral water on hairless mice skin applied with DNCB inhibited the development of AD-like skin lesions as exemplified by a significant increase in skin hydration (p<0.01), and a decrease in epidermal water loss (p<0.01). Serum IgE level was also significantly decreased (p<0.01). These results suggest that magnesium-rich sea mineral water inhibits the development of DNCB-induced AD-like skin lesions in hairless mice. These observations indicate that magnesium-rich sea mineral water may be alternative and assistant substances for the management of AD.
