  • 동양의학에서 강정 강장제로서의 귀히 여겨지는녹용의 유효성분과 또한 녹각과 그 유효성의 차이를 찾기 위해 무기질, 아미노산과 지방산 조성 등을 비교 검토하였다. 무기질 조성은 녹용과 녹각에서 Ca의 함량이 제일 높았고, Na과 K 함량도 상당히 높았으며 Hg 등 중금속은 전혀 검출되지 않았으며, 녹각에서는 Mn과 Fe이 미량 검출되었다. 녹용의 지방산은 포화지방산보다 불포화지방산 함량이 월등히 높았으며 그 중에서도 동맥경화증을 경감시킨다고 하는 docosahexaenoic acid가 43.73%로 제일 높았고, 녹각에서는 녹용에 비해 전반적으로 함량이 낮았다. 아미노산은 녹용에서 총 17종이 검출되었는데, glycine 함량이 제일 높았고, alanine과 proline 순이었다. 이는 collagen이 녹용의 상당부분을 차지한다는 것을 시사하며, 녹각에서는 비록 함량은 적었지만 10종이 검출되었으며, glutamic acid, proline, glycine과 alanine 등도 상당히 함유되어 있었다.

  • This study designed not only to elucidate free amino acid, fatty acid composition and mineral content in dried alaska pollack but also to examine calcium, magnesium, poassium and sodium contents in its cooking broth according to each boiling time such as 2.5, 5, 10, 20, and 30 minutes. RESULTS : 1. Glutamic acid in dried alaska pollack was the most abundant free amino acid and was followed in order of aspartic acid, lysin, leucine and histidine. They composed of 50.95% of the total amino acid contents. 2. In dried alaska pollack the most abundant fatty acid was palmitic acid. Essential fatty acid content was 26.57% of the total fatty acid. 3. The calcium, magnesium, potassium and sodium contents in dried alaska pollack showed 10.721 mg%, 9.235mg%, 4072.5mg% and 2299.8% respectively. The amount of magnesium and potassium in cooking broth arrived at the highest level when 20 minute boiling was undertaken and the quantities of magnesium and sodium were the highest when 30 minute boiling was made.

  • 인체 경조직인 뼈와 치아는 콜라겐 단백질과 인산칼슘 무기질 성분으로 구성된 최적의 복합체라 볼 수 있다. 이러한 인산칼슘 무기질 성분은 결정학적, 화학적으로 hydroxyapatite (HA, Ca10(PO4)6(OH)2)와 거의 유사하여 높은 생체활성과 골전도성을 보이는 것으로 알려져 있다. 또한, hydroxyapatite의 고온 분해 산물로 볼 수 있는 tricalcuim phosphate(TCP, Ca3(PO4)2)는 체내에 이식시 체액에 용해되어 신생골을 유도하는 생체흡수성 세라믹스로 알려져있다. 이러한 HA와 TCP는 우수한 생체친화성에도 불구하고 기계적 특성이 낮아, non-load bearing 부위에 적용이 되어 다공질의 골수복재 용도로 활용되거나, load-bearing부위의 적용을 위한 금속 implant 등의 생체친화성 보완을 위한 표면 코팅재로 사용되고 있는 실정이다. 본 발표에서는 생체특성이 매우 우수한 인산칼슘 생체세라믹스의 load-bearing part 적용을 위하여 강도 및 파괴인성의 기계적 특성을 증진시킨 사례를 살펴보고, non-load bearing part에 실제 사용되는 인산칼슘 생체세라믹스의 다공질(porous) 골수복재(bone graft)의 역학 특성 증진을 위한 아이디어와 함께, 역학 특성이 매우 뛰어난 지르코니아 생체세라믹스의 강화-소결법에 대하여 소개하고자 한다.

  • This study was to determine the efficacy in the remineralization on premary teeth following the application of toothpaste with and without sodium fluoride. All tooth were checked using microhardness tester and the calcium (Ca) and phosphorous (P) concentration by electron probe microanalyzer (EPMA) analysis for the 4 weeks. The collected data was analysed using the statistical software program SPSS, 20.0. The applied enamel of premary teeth with 0.243% fluoridated toothpaste resulted in significant differences in the microhardness values (p>0.05). The Ca and P concentrations of applied premary teeth with fluoridated toothpaste were also significant difference in norm wt% (p>0.05). As a results, a increasing the surface microhardness of the premary teeth and providing a remineralizing effect by increased Ca and P concentrations.

  • This research is carried out to investigate the formation and preservative effectiveness of inorganic substance, calcium carbonate($CaCO_3$), in wood. The specimens were prepared by the impregnation with saturated solutions of potassium carbonate($K_2CO_3$) into the wood followed by precipitation in saturated solutions of calcium chloride($CaCl_2$) for 24h, 72h and 120h, and then they were leached in instrument flowing with water for 24h. The weight percent gains of $K_2CO_3$ solution impregnated specimens reached approximately a maximum value (108.1%) by 72h precipitation in $CaCl_2$ solutions. Inorganic substances were observed to he produced in the lumina of tracheids of specimens. From these inorganic substances filling in the tracheids, characteristic X-rays of calcium(Ca-$K_{\alpha}$) were detected by energy dispersive X-ray analyzer. Moreover, it was shown from a leaching treatment that these substances could not he leached easily from the specimens. Therefore, they were could he considered to be insoluble calcium carbonates. The weight losses of the prepared specimens were hardly occurred by test fungi attacks. Thus inorganic substances in specimens can be said to have preservative effectiveness.

  • This study was conducted to get a knowledge on food components of cuttle bone (CB) as a food resource. The yields and ash contents of CB were about $7.5\%$ on whole cuttle fish and about $90\%$ on dry basis, respectively, The contents of heavy metal might not invoke health risk in using food resource, The major mineral of CB was calcium as about $22\%$ in content. The yields, proximate compositions, heavy metal and mineral contents were not significantly different between domestic and imported CB. Judging from X-ray diffraction pattern, most of calcium in CB was present as a form of calcium carbonate (CC), and scanning electron micrograph showed irregular form. Buffering capacity of CB showed strongly at pH 7, and its pattern was the same as shown in that of CC, And CB solution showed a very high degree in turbidity comparing to that of CC solution. The solubility of CB was superior to that of CC, but inferior to those of calcium powders on the market, It was concluded from above results that CB could be effectively utilized as a calcium source.

  • General component and mineral contents according to species of Capsicum annuum were investigated. In addition, chuichung cucumber, white dadagi cucumber, and yellowish overripe cucumber were cooked by using seven different methods (boiling, steaming, pan-cooking, roasting, pan-frying, deep-frying, and microwaving), and retention rates of general components and minerals according to species were evaluated. Weight loss was observed in all cucumber species using all cooking methods. Most general component and mineral contents of C. annuum samples were significantly different according to species, and cooking method (P<0.05), whereas Fe and Cu contents were not significantly affected by species and cooking method, respectively. As a result, the highest protein, fat, ash contents were detected in deep-fried C. annuum, and high moisture contents were detected in raw, boiled, and steamed C. annuum. High mineral contents were detected in roasted and microwaved chuichung cucumber, deep-fried white dadagi cucumber and yellowish overripe cucumber. Retention rates of C. annuum by cooking method, ranged from 30~100% for protein, 10~100% for fat, 35~90% for moisture, and 30~100% for ash. High retention rates were observed for minerals in boiled, roasted, and microwaved chuichung cucumber, and deep-fried white dadagi cucumber and yellowish overripe cucumber. However, in yellowish overripe cucumber, mineral retentions rate were remarkably lowered by boiling and steaming, resulting in rates of 20~45%. These results were the data used as the basis for development of cucumbers.

  • A Comparative study was performed among five Korean wheat(Greu, Eunpa, Tapdong, Allgreu, Woori) and three imported wheat(Dark Northern Spring, Austrian Standard Wheat, Western White) to investigate the characteristics of minerals and phytate from Korean wheat varieties. Ash contents of kernel was higher in Korean wheat than in imported wheat and related to ash contents and darkness of flour. More contents of Fe, P, and Mg from Korean wheat grains and Fe from Korean wheat flours were observed in comparison to imported wheat varieties. Fe concentration in Korean flour show high, indicating Fe was distributed at endosperm layer of kernels and not eliminated with milling. In addition, phytate affecting availability of minerals was determined from kernels and flours. Even though Korean wheat kernels had more phytate than that of imported wheat kernels, it is believed that most of phytate was removed with milling and there was no major difference between Korean and imported wheat flours. We also observed that the content of phosphate closely parallels the content of phytate from both the flours and kernels.
