韓醫學으로 보는 文宗의 疑問死에 대하여

이종호(Lee, Jong-Ho),안덕균(Ahn, Duk-Kyun) 백산학회 2009 白山學報 Vol.- No.83

The authors explained the hypothesis that Moonjong of Lee's Dynasty maybe died by the unexplaining treatment of the Medical Officer named JeonSoonEu. Moonjong had very slight desease called swelling, but Medical Officer gave him very poisonous Pinellia ternata in Pheasant meat, So he suddenly died in the three year of reign means very short period among the Lee's Dynasty. Generally Pheasant like to eat Pinellia ternata during the Summer, So If one want to eat the Pheasant meat must waite till the winter. Because during the winter Pheasant can't found the Pinellia ternata, so Pheasant meat not toxic. ... Who is the orderer, are not yet reaveled instead of JeonSoonEu. One cann't give the confidence as a prime mover of JeonSoonEu, because he is only one of the Medical Officier. So one thinks that probably SeJo, the younger brother, one of the most powerful king during the Lee's Dynasty is the main suspecter. Sejo killed the nephew Danjong, Son and succesor of MoonJong, and catch the reins of government by 'coup d'etat’. If Sejo connect with the Moonjong's died, maybe he is the only one suverean who killed the two kings overall the Korean history.

Apophyseopathy in human growing-up period is divided in three parts, early stage, advancing stage, and ending stage which are analyzed by X-ray test. The tuber of kantenabtrennung, schmorl and rear oxhorn dissociation are one of the these barrier process. We assume that the fracture of apophysis by overusing is the main cause of these barriers.

유전자재조합 인간 골형성단백2 및 생흡수성고분자를 이용한 골형성유도체의 개발

이장희,김각균,안강민,김종원,이종호 大韓顎顔面成形再建外科學會 1999 Maxillofacial Plastic Reconstructive Surgery Vol.21 No.4

We tested the bone regenerating capacity and histologic response of bioresorbable matrix-type implant, which was made with Poly(lactide-co-glycolide)(PLGA) and bone apatite for the carrier of bone morphogenetic protein(BMP). The critical size defect of 8mm in diameter was created at the calvaria of SD rats(n=18), and repaired with polymer implant with 15㎍ of rhBMP-2(n=9) or without it(n=9). At 2 weeks, 1 months after implantation, the animals were sacrified(3 animals at every interval and group) and histologically evaluted. The calvarial defect which was repaired with polymer with BMP healed with newly formed bone about 70% of total defect. But that without BMP showed only 0 to under 30% bony healing. Inflammtory response was absent in both group through the experimental period, but there's marked foreign body giant response though it was a little less significant in polymer with BMP group. As the polymer was resorbed, the space was infiltrated and replaced by fibrovascular tissue, not by bone. In conclusion, our formulation of bioresorbable matrix implant loaded with bone morphogenetic protein works good as a bone regenerating material. However, it is mandatory to devise our system to have better osteoinductive and osteoconductive property, and less mutinucleated giant cell response.

이종오,정동균 대한구강생물학회 1986 International Journal of Oral Biology Vol.10 No.2

This experiment was performed to study the effects of colchicine and verapamil on PTH-induced bone resorption in organ culture. Ulnae and radii were removed from 19-day fetal rats, prelabelled by subcutaneous injection of 200μCi ^45CaCl_2 into their mothers on the 17th day of gestation, and then explanted on the Millipore filters in organ culture dishes. The media of normal group were exchanged with fresh media, and control group with 0.1U/ml PTH-supplemented media, while experimental group, were exchanged with 0.1U/ml PTH+10^-7M colchicine, PTH+40μM verapamil, or PTH+10^-7M colchicine+40mM verapamil complexed media. Radioactivity of ^45Ca released into media after 24, 48 and 72 hours of culture and remained in cultured bone after 72hours, were both determined. The rates of bone resorption in each group were measured by the percentage of released ^45Ca to the total radioactivity that presented in the bone at the beginning of culture. And also effects of colchicine, verapamil and colchicine+verapamil were observed by the ratios of %-release of ^45Ca between paired control and experimental group. The following results were obtained: 1. PTH at the concentration of 0.1U/ml, increased the fetal bone resorption by 67 and 87% after 48 and 72hours of culture, respectively 2. Colchicine, at the concentration of 10^-7M, presented significant inhibition of PTH-induced bone resorption after 48 and 72 hours of culture, and verapamil, at the concentration of 40μM, presented significant inhibition of the PTH-tnduced bone resorption after 72 hours of culture. 3. Colchicine plus verapamil at the concentration of 10^-7M and 40μM, respectively, presented significant inhibition of PTH-induced bone resorption after 48 and 72hours of culture, but presented lack of additive or synergistic effects.

This experiment was performed to elucidate the reported anti-cariogenic effect of capsicum in rats. Streptococcus mutans strain B-13, which was drived from human oral cavity and known to be cariogenic, was cultured in TYG with water-extract of capsicum. Glucose content of water-extract of capsicum was also determined by glucose oxidase method. The results are as follows. 1. Glucose content of water-extract of capsicum was 25.6 (±0.5) %. 2. In logarithmic phase, water-extract of capsicum group showed less steepness in growth curve than control group. 3. In early stationary phase, size of bacterial cell mass was in order of control, 0.5% and 1% water-extract of capsicum group. 4. It appears that water-extract capsicum might contain inhibitory substance to growth of Streptococcus mutans B-13, in spite of its high glucose content.
