  • 사탕무우 품종 Mirabo를 공시하여 수경과 포양실험을 통하여 나타는 B결핍증 식물체의 해부학적 및 전현적 관찰을 하였다. B결핍증에 걸린 사탕무우에 있어서는 수경또는 포양에서 다 같이 B함량이 매우 적었다. B결핍증의 증상진행은 우선 엽병의 표면쪽 기부에 흑갈색 줄이 나타나기 시작하였으며, 그 후 유엽록과 생장점 근처가 검게 괴사하였고, 엽신이 심하게 오그라졌으며, 생장이 거의 정지되었다. 나중에는 표면쪽 엽병 기부의 표피와 그 밑의 유조직이 괴사하였다. 그리고 유엽록 조직의 괴사와 붕괴는 점차 확대되어 갔다. B결핍증을 나타낸 사탕무우의 전현적 관찰에서는 그와 같은 식물의 엽록체는 붕괴하기 시작하였으며 다량의 전분과 Osmophilic granules가 보였다. 그리고 특히 어떤 엽록체 안에는 격자를 가진 다면체의 결정체가 발견되었다.

  • Common cold occurs frequently and occupies an important position in medical treatment however obvious treatment is not suggested. There has been no agreement of pattern identification for common cold in oriental medicine. The purpose of this study is to develop a standard instrument of pattern identification for common cold which will be applied to clinical research. The items and structure of the instrument were based on review of published literature. The advisor committee on this study was organized by 9 oriental respiratory internal medicine professors of 11 oriental medical colleges nationwide. The experts attended 3 consultation meetings and discussed developing the instrument, and we also took professional advices by e-mail. The results were as follows; First, we divided the pattern identification of common cold into nine pattern: Wind-cold type, Wind-heat type, Contain summerheat type, Contain dampness type, Qi deficiency type, Blood deficiency type, Yang deficiency type, Yin deficiency type, Influenza. Second, we got the mean weights to each symptom of nine pattern identification which had been scored on a 5-point scale - ranging from 0 to 4 by the 9 experts. Third, we made out the Korean instrument of the pattern identification for common cold. It was composed self reporting questionnaire and researcher reporting questionnaire. Though this study is not proved about validity, reliability, the instrument of pattern identification for common cold is meaningful and expected to be applied to the subsequent research. And also, we hope to improve the instrument and make up for this study through various research and discussion.

  • A disease of young Holstein calves characterized by recurrent pneumonia, ulcerative and granulomatous stomatitis, enteritis with bacterial overgrowth, periodontitis, delayed wound healing, persistent neutrophilia and death at an early age had been originally described in 1983 and again in 1987. Most of these calves had stunted growth and a persistent, progressive neutrophilia (often exceeding 100,000/ml). By investigation of pedigrees, all of the affected calves have now been traced to a common sire and confirmed by polymerase chain reaction (PCR) diagnostic DNA testing to be homozygous carriers of a defective allele for bovine CD18. Neutrophils from these calves have several functional deficits and, most importantly, fail to adhere in a ${\beta}_2$-integrin dependent manner. The ${\beta}_2$-integrins represent a family of glycoproteins which participate in various leukocyte adhesion reactions during host defense. The presence or absence of ${\beta}_2$-integrin molecules can be demonstrated on the surface of neutrophils, monocytes and lymphocytes from normal or affected calves using specific monoclonal antibodies and flow cytometry, or by colloidal gold immunolabeling and scanning electron microscopy in backscatter mode. Deficiency of the ${\beta}_2$-integrins on all leukocyte types in Holstein calves is analogous to leukocyte adhesion deficiency (LAD) seen in humans. Neutrophils in bovine (BLAD) and human LAD patients are unable to adhere to the endothelial lining of the cardiovascular system thus interrupting egression of neutrophils into infected tissues. Other leukocytes, while still deficient in expression of the ${\beta}_2$-integrins, are still able to efficiently egress from the blood stream due to interactions of other adhesion molecules that are not as highly expressed on neutrophils. Both BLAD cattle and LAD children (who do not receive bone marrow transplants) often die at an early age as a result of the failure of neutrophils to extravasate into infected tissues. In 1991, Shuster, et $al^{27}$, identified two point mutations within the alleles encoding bovine CD18 in a Holstein calf afflicted with leukocyte adhesion deficiency. One mutation causes an aspartic acid to glycine substitution at amino acid 128 (D128G) in an extracellular region of this adhesion glycoprotein that is highly conserved (> 95% identity) between humans, cattle and mice. The other mutation is silent. Numerous calves with clinical symptoms of leukocyte adhesion deficiency have since been tested and all have been found homozygous for the D128G allele. In addition, calves homozygous far the D128G allele have been identified during widespread DNA testing in the United States. All cattle with the mutant allele are related to one bull, who through artificial insemination (A.I.), sired many calves in the 1950's and 1960's. The carrier frequency of the D128G CD18 allele among U.S. Holstein cattle had reached approximately 15% among active A.I. bulls and 8% among cows. By 1993, the organization of the dairy industry and the diagnostic test developed to genotype cattle, enabled virtually complete eradication of bovine leukocyte adhesion deficiency among current and future A.I. bulls.

  • Obejective : Based on ${\ll}$sixty-ninth Nan${\gg}$ (${\ll}$難經${\cdot}$六十九難${\gg}$) the interpromoting of the five element's balance method to discuss following 'when deficiency than should strengthen mother and when excessive than eliminate son' theories. Method : This strengthening and eliminating method is based on Jang-bu organ's balance method when 'east is excessive (liver excessive (肝實 )) and west is deficiency (lung deficiency (肺虛))' then 'eliminate the south and strengthen the north's method. Results : The seventy-fifth Nan (${\ll}$難經${\cdot}$七十五難${\gg}$) explains' son effects mother's excessive and mother effects son's deficiency' theory where it balance method of the inter-overacting five elements controlling Jang-bu organ's differentiations. The eighty-first Nan (${\ll}$難經${\cdot}$八十一難${\gg}$) explains strengthening-eliminating method of 'lung excessive and liver deficiency.' Since there are two different perspective of seventy-fifth and eighty-first Nan, we must compare and discuss to make right point of view. Conclusion : the treatment method in ${\ll}$Nan kyoung sixty ninth nan${\gg}$ could be understood as a view of five element constitutional theory (五行體質理論), the treatment method in ${\ll}$Nan kyoung seventyty-fifth nan${\gg}$ of eleminating fire and strengthning water in case of liver excess and lung defficiency and the treatment method in ${\ll}$Nan kyoung eighty-first nan${\gg}$ of strengthning liver and eleminating lung in case of lung excess and liver defficiency could be understood as a view of the yin-yan constitutional theory (陰陽體質理論).

  • Wernicke's encephalopathy (WE) is an acute neurological disorder resulting from thiamine deficiency. Early diagnosis and treatment of WE is important to avoid persistent brain damage. Although histopathologic examination usually demonstrates pin-point hemorrhages in affected brain parenchyma, secondary hemorrhage is a rare but serious complication of WE. We experienced a rare case of intracranial hemorrhage related to WE in a 56-year-old male patient with malnourishment.

  • The problem of estimating a smooth distribution function F at a point $\tau$ based on randomly right censored data is treated under certain smoothness conditions on F . The asymptotic performance of a certain class of kernel estimators is compared to that of the Kap lan-Meier estimator of F($\tau$). It is shown that the .elative deficiency of the Kaplan-Meier estimate. of F($\tau$) with respect to the appropriately chosen kernel type estimate. tends to infinity as the sample size n increases to infinity. Strong uniform consistency and the weak convergence of the normalized process are also proved.

  • Chronic fatigue syndrome is an agonizing illness that impedes the quality of life of people worldwide. Although this syndrome is reported to be increasing in industrialized countries, there are as yet no effective therapies. In the view of Oriental medicine, chronic fatigue syndrome is thought to result from a state of unbalanced inter-organ functions, or a condition of deficiency in the qi or blood characteristics. On the other hand, chronic fatigue-related symptoms are one of the most common complaints of patients using complementary and alternative medicine. This study aimed to theoretically analyze chronic fatigue syndrome from an Oriental medicine point of view, so to help Oriental doctors to design appropriate therapeutic models.

  • Purpose: Serum level of 25-hydroxyvitamin D (25-OHD) is considered as the most appropriate marker of vitamin D status. However, only a few studies have investigated the relationship between 25-OHD and parathyroid hormone (PTH) in children. To this end, this study was aimed at evaluating the lowest 25-OHD level that suppresses the production of parathyroid hormone in children. Methods: A retrospective record review was performed for children aged 0.2 to 18 years (n=193; 106 boys and 87 girls) who underwent simultaneous measurements of serum 25-OHD and PTH levels between January 2010 and June 2014. Results: The inflection point of serum 25-OHD level for maximal suppression of PTH was at 18.0 ng/mL (95% confidence interval, 14.3-21.7 ng/mL). The median PTH level of the children with 25-OHD levels of <18.0 ng/mL was higher than that of children with 25-OHD levels ${\geq}$ 18.0 ng/mL (P<0.0001). The median calcium level of children with 25-OHD levels<18.0 ng/mL was lower than that of children with 25-OHD levels${\geq}18.0ng/mL$ (P=0.0001). The frequency of hyperparathyroidism was higher in the children with 25-OHD levels<18.0 ng/mL than in the children with 25-OHD levels${\geq}18.0ng/mL$ (P<0.0001). Hypocalcemia was more prevalent in the children with 25-OHD levels<18.0 ng/mL than in the children with 25-OHD levels${\geq}18.0ng/mL$ (P<0.0001). Conclusion: These data suggest that a vitamin D level of 18.0 ng/mL could be the criterion for 25-OHD deficiency in children at the inflection point of the maximal suppression of PTH.

  • Objectives & Methods: We investigated 36 books to study etiology, pathology and acupuncture & Moxibustion treatment of Gak-Gi Result and Conclusion 1. Gak-Gi is a disease of legs. In the past, it was called Wan-poong(緩風) or Gueol(厥). Currently it is divided into two kinds; the Seup-Gak-Gi(Damp Gak-Gi) in which the legs swell; The Gun-Gak-Gi(Dry Gak-Gi) in which the legs do not swell. 2. Gak-Gi may be caused by exogenous wind, coldness, dampness and Excess of phlegm or damp-heat. It also can be caused by weakness of vital energy(Myungmoon fire;命門火), kidney Yin deficiency and vital energy deficiency in the Stomach and Spleen. 3. Gak-Gi-Pal-Hyul(Eight acupoints for Gak-Gi; 脚氣八穴) are GB31(Poonsi; 風市), ST32(Bok-to; 伏兎), ST35(Dok-bi; 犢鼻), Nae-seul-an(Extra point; 內膝眼), ST36(Chok-samni; 足三里) ST37(Sang-goho; 上巨虛) ST39(Hagoho; 下巨虛) GB41 (Choc-imup; 足臨泣) 4. Treatment plans for Gak-Gi are removing the exogenous wind, coldness and dampness, regulating meridians, alleviating the pain and swelling, more importantly, tonifying vital energy and nourishing Spleen and Stomach. 5. Three out of Eight acupoints for Gak-Gi, ST36(Chok-samni; 足三里), ST37(Sang-goho; 上巨 虛), ST39(Hagoho; 下巨虛) are Lower sea points of Fu organs( Stomach, Large Intestine, Small Intestine). Five out of Eight acupoints for Gak-Gi, ST32(Bok-to; 伏兎), ST35(Dok-bi;犢鼻) are onthe Stomach meridian, and Nae-seu1-an(Extra point; 內膝眼) is on the Spleen meridian. This result indicates that regulation of Middle-cho(中焦) is important in the treatment for Gak-Gi.

  • The purpose of this study was to report the effect of GwiBiTang and gagambang, acupuncture and moxibustion on essential tremor. This study was made on 6 cases that were treated in the OO University Oriental Medicine hospital and evaluated tremor using Visual Analogue Scale(VAS). GwiBiTang was one of the most generally used herbal medication, diagnosed as dual deficiency of the heart-spleen. In five patients out of six, VAS scores decreased. Two patients's scores decreased to 0 point. Three patients's score decreased to 2, 5 and 6 point, respectively. One patient was maintained on these Korean medical treatment for 26 days with no decrease of VAS score in tremor. The overall therapeutic effect was "markedly improved" in 2 (33.3%), "moderately improved" in 3 (50%), "poor" in 1 (16.7%). The results obtained this study suggest that GwiBiTang and gagambang, acupuncture and moxibustion might be effective in the treatment of tremors. Future studies will be required to ascertain the effect of GwiBiTang.
