한국에서 자생한 자연산 tumor 조직과 근권토양으로부터 형질전환율이 높은 hypervirulent Agrobacterium spp를 분리하기 위해서 Salix, Diospyros, Populus 및 Malus에서 형성된 tumor 조직과 근권토양을 채취하괴 Schroth 선택배지와 New and Kerr 배지를 이용하여 78 균주의 colony를 특성에 따라 분리하였다. 이중에서 48 균주가 당근 disc에서 tumor를 형성하였으며 tumor를 형성한 균주중 형성시기가 빠르며 크기가 커 hypervirulent 균주로 생각되는 A. tumefaciens SP101을 biotype 1, 그리고 A. tumefaciens SM042를 biotype 2로 동정하였다. 토양중에서 선발한 A. tumefaciens SM042와 disarmed A. tumefaciens PC2760에 kanamycin 저항성 유전자를 함유하고 있는 binary vector pGA643을 도입하여 conjugant인 A. tumefaciens SM643과 A. tumefaciens PC643을 kanamycin과 tetracycline이 함유된 최소배지에서 획득하였다. 연초의 형질전환을 위해서 conjugant Agrobacterium과 연초조직을 동시배양 후 2,4-D와 kanamycin이 함유된 선발배지에 치상하여 형질전환을 유도한 결과 A. tumefaciens SM643이 A. tumefaciens PC643보다 더 많은 캘러스가 형성되었다. 그러나 A. tumefaciens PC643을 사용한 형질전환 캘러스는 대부분 friable한 캘러스로 유도되었으며 정상적으로 식물체로 생장하였으나 A. tumefaciens SM643을 사용한 캘러스는 매우 딱딱하며 둥그런 형태의 캘러스와 friable한 캘러스가 혼재한 상태로 생장하였으며, 이중에서 friable한 캘러스는 정상적인 shoot가 형성되었으나 딱딱한 캘러스로 유도된 형질전환체는 식물체로 형성되지 않고 반구형 미색의 전형적인 tumor 캘러스로 생장하였다. 한편 형질전환시 캘러스를 유도하지 않고 직접 shoot를 형성시킨 결과 disarmed Ti-plasmid를 사용하지 않고 wild-type Ti-plasmid를 사용해도 정상적인 형질전환체를 획득할 수 있었다.

Purpose: The present study examined the effectiveness of the preoperative ischemia-modified albumin (IMA) levels in predicting the healing period of amputation wounds in patients with diabetes mellitus following a non-traumatic below-knee amputation (BKA). Materials and Methods: This study enrolled 41 diabetic foot ulcer patients who underwent BKA at the authors' hospital diabetic foot center from April 2016 to April 2022. Among the 41 patients, 29 (70.7%) were male and 12 (29.3%) were female. Their mean age was 64.54±11.38 years (41~81 years). The mean follow-up period was 19.48±5.56 weeks (14~48 weeks) after BKA. The patients were divided into two groups (high IMA group and normal IMA group), which evaluated the healing period, wound dehiscence, and revision operation rate using a Fisher's exact test and Mann-Whitney U test. Three orthopedic surgeons performed stump wound evaluation, and they were evaluated as healing when all sutures were fused without oozing. Results: Thirty patients (73.2%) (group A) showed a high level of IMA (median: 91.2 U/mL), and 11 (26.8%) patients (group B) showed a normal range of IMA (median: 82.7 U/mL). In group A, the median period for wound healing took 1.4 weeks longer, which was significant (p=0.001). No statistical relationship was observed between wound dehiscence, revision operation rate, and IMA value. There was no correlation between the other risk factors (estimated glomerular filtration rate, HbA1c) and the wound healing period. Conclusion: Although there was a limitation in using IMA as the sole factor to predict the healing period of amputation wounds in patients after BKA, this study revealed a significant positive correlation between IMA and the period of stump healing after BKA. Therefore, the preoperative IMA levels may help predict the period of stump healing after BKA.

당뇨병 노인환자의 자기관리 교육은 대상자의 건강행위를 변화시켜야 하는 목표를 성취해야하므로 노인의 자기관리 역량 강화에 중점을 두고, 노인 대상자의 특성과 개별적인 상황 및 조건을 반영해야 한다. 그러나 이러한 노인 특화 프로그램은 매우 제한적이고, 대상자 중심의 효과가 평가된 경우도 드물다. 이에 본 연구는 노인복지관을 이용하는 지역사회 거주 당뇨병 노인 맞춤형 당뇨자기관리 프로그램을 실행연구 방법으로 적용하고, 그 효과를 평가하기 위해 시행되었다. 본 연구는 실행연구방법의 계획, 실행, 평가, 성찰단계를 각 회기마다 시행하여 이전 회기의 결과가 다음회기의 중재계획의 변화에 근거가 되는 체계적인 순환과정을 3회기에 걸쳐 순차적으로 적용하였다. 일개의 지역사회 복지관에서 15개월에 걸쳐 12주의 소규모 노인 당뇨병 교육 프로그램을 제공한 후 양적, 질적 자료를 모두 사용하여 참여대상자 측면의 평가가 충분히 포함되도록 하였다. 총 46명중 43명(93.48%)이 프로그램을 이수하였다. 양적인 프로그램의 효과결과에서는 당화혈색소(p<.001), 공복혈당(p<.001), 신체질량지수(p=.016), 허리둘레(p=.001), 수축기혈압(p=.036), 당뇨병 자기관리 행위(p<.001), 노인 건강행위지식(p=.008)이 통계적으로 유의하게 향상되었다. 질적 평가 자료에서는 본 프로그램은 개별적인 맞춤 관리로 느껴지며 이를 통해 역량 강화하게 되었고, 상호작용을 통한 능동적인 참여를 통해 자신의 자기관리 이행에 자신감과 실천의 즐거움을 느꼈다고 하였다. 본 연구는 실행연구방법을 적용하여 지역사회 노인을 대상으로 당뇨병 교육 프로그램을 적용한 결과로 대상자의 신체적 지표와 행위지표, 유용성 등의 양적인 효과뿐만 아니라 대상자 측면에서의 주관적인 효과성을 확인 한 것은 효율성과 실현 가능성을 살펴보는 의미 있는 시도였다. 따라서 이러한 실행연구 방법을 통한 프로그램의 적용과정과 평가는 현장 실무자에게 대상자의 요구 중심의 맞춤형 중재 프로그램 시행의 가이드가 될 것이다.

This study was designed to investigate the effects of iron supplementation and nutrition education on the iron status and anemia of high school girls. The subjects resided in Ulsan city in Korea and were already diagnosed as having anemia or iron deficiency. Over a period of three months, one iron tablet (80 mg Fe as ferrous sulfate/day) was administered to the iron deficient subjects and two tablets (160 mg Fe as ferrous sulfate/day) were administered to the anemia subjects. The average height and weight of anemia subjects were 161.24 $\pm$ 4.50 cm and 50.87 $\pm$ 5.86 kg, respectively. The average BMI (kg/$m^2$ )was 19.58 $\pm$ 2.03 and the PIBW(percent ideal body weight) were 92.52 $\pm$ 9.84%. Except for vitamin A and vitamin C intakes, the intake levels of all other nutrients were below the RDA. Total calorie intakes of anemia subjects were 73.5% of RDA. The iron intakes of subjects from food were 69. 1% of RDA and the Ca intakes were 59.1% of RDA. The basal hemoglobin(Hb) concentration of anemia subjects averaged 10.77 $\pm$ 1.33 g/dl, and this increased significantly (p < 0.001) to 12.12 $\pm$ 1.08 g/dl, after iron supplementation. The basal ferritin, and transferrin saturations ｛TS (%)｝of anemia subjects were 12.51 $\pm$ 15.19 ng/$m\ell$ and 8.43 $\pm$ 7.56%, respectively, and these significantly increased to 20.59 $\pm$ 22.39 ng/$m\ell$ and 15.56 $\pm$ 12.87%, respectively. The level of total iron binding protein (TIBC) significantly decreased from the initial 486.80 $\pm$ 70.16 $\mu\textrm{g}$/dl to 417.86 $\pm$ 67.73 $\mu\textrm{g}$/dl (p < 0.001) after iron supplementation. For the iron deficiency subjects, the ferritin, iron and TS(%) levels were increased significantly (p < 0.001) and the TIBC levels were significantly (p <0.001) decreased after iron supplementation. Anemia symptoms such as 'Feeling blue (p<0.05)', 'Decreased ability to concentrate (p<0.001)' and 'Poor memory (p<0.05)' improved significantly after iron supplementation in the anemia subjects. The number of tablets administered was positively correlated with changes in serum hemoglobin (t=0.194, p< 0.01), serum ferritin (t=0.181, p<0.01), TS(%) (t=0.141, p<0.05), and hematocrit (t=0.254, p<0.01), and was negatively correlated with changes in TIBC (t=-0.143. p<0.05) and red cell distribution width (RDW, t=-0.140, p<0.05). In conclusion, daily iron supplementation was effective in improving the iron status and reducing symptoms of anemia in high school girls. (Korean J Nutrition 35 (9) : 943~951,2002)

Background: This study aimed to properly manage diseases such as blood sugar control so that patients with diabetes can benefit from both medication and health activities. Also, these health practices are greatly influenced by self-rated health, a subjective assessment of health status. Because self-rated health does not necessarily match the objective health status, it is important to identify which factors affect self-rated health. Methods: For the study, the data was gathered from the 4th-6th National Health Nutrition Survey (2007-2015). Out of the total 73,353 participants in the survey, 2,303 patients with uncontrolled blood sugar with an HbA1c level of more than 7% were selected for the final study. Dependent variables fell into two categories depending on how the participant reported whether he or she was in good health or not. Independent variables included socio-demographics, health behavioral, and health status factors. This study performed logistic regression analysis. Results: Out of 2,303 participants, 18.1% reported that their heath was 'good,' despite the fact that their blood sugar level was not controlled. After running a logistic regression model, the odds ratio of groups that perceive subjective health awareness as good was higher in the groups of people as below: in the people over 60 years old; in the people who graduated from a junior college or higher than those who had a level of education of primary school completion or less; in the people living in Chungnam than those living in Seoul; and in the group with hypertriglyceridemia. Conclusion: The study identified factors associated with those failed to perceive the blood sugar level as a severe health problem despite of the fact that blood sugar was not controlled. To improve public health, diabetes management policies need to be addressed to population groups with these problems above.

Background: Diabetes is accompanied by complications. One of the chronic complications, diabetic retinopathy is the most common cause of the loss of eyesight and thus has enormous impacts on the quality of life to the patients. It has been reported that thorough glucose regulation can prevent or postpone the outset of diabetic retinopathy in diabetic patients and that the patients who received anti-diabetic manage & care education would be capable of more thorough glucose-level regulation than those who did not. Method: This study set out to investigate the current state of education on anti-diabetic manage & care in South Korea and connections between anti-diabetic manage & care education and occurrence of diabetic retinopathy in diabetic patients based on the Korea National Health and Nutrition Examination Survey of 2011. Results: Of the 410 diabetes patients, 74 received anti-diabetic manage & care education, which means that only 15% of diabetic patients benefited from the education in the nation. The occurrence rate of diabetic retinopathy was 28% in the education group and 24% in the non-education group with no significant differences between them. The anti-diabetic manage & care education group recorded a higher occurrence rate of diabetic retinopathy, one of the chronic diabetic complications, than the non-education group contrary to the hypothesis. One of the reasons was that the educated group had a significantly longer duration of diabetes and significantly higher HbA1c than the noneducated group, which indicates that anti-diabetic manage & care education is provided to those who have progressed farther along the course of diabetes instead of the early stage and cannot regulate their glucose-level well in the nation. Conclusion: Those findings raise a need for active educational policies in order to provide anti-diabetic manage & care education under the goals of preventing complications through anti-diabetic education for many patients in early stages of diabetes.

Objectives : JianTeng-Yuan(交藤圓) is said to be a prescription for preservation of health in ${\ulcorner}$HuaTuo ZhongZangJing(華陀 中藏經)${\lrcorner}$. It is known to have the effect of Bu-Shen(補腎: strengthening kidney) and Yi-Shou(益壽: prolonging the span of one's life). This study investigates whether JTY is effective on inhibition of oxidation stress. Methods : Sprague-Dawley Rats(12-week-old, weight $300{\pm}20g$) were divided into 3 groups. Normal group(n=8) was injected PBS(1ml/body, s.c) at the back neck's skin. Control group(n=8) was injected D-galactose(50mg/kg, 1ml PBS/body, s.c) to induce pathological animals. JTY group was injected the same treatment for the Control group, and fed containing JTY(10%). The whole groups were treated 1 time per day for 6 weeks. After rats were sacrificed and anti-oxidant enzyme(SOD, CAT, G-px) activity, GSH quantity of RBC and tissue(heart, liver and kidney), plasma Vit-C quantity were examined. Besides, the MDA levels of liver and kidney, lipofuscin of heart and endurance of erythrocyte membrane were measured. Results : In the JTY group, RBC's SOD activity decline was halted by 21% of the normal level, compared to the control group ; G-px activity(unit/g of Hb) increased significantly, compared to the normal group ; and the level of Vit-C in plasma increased by 16%. Heart's SOD activity was kept at the same level as that of the normal group ; and CAT activity decline was halted by 26%. Kidney's CAT and G-px activities were kept at the same level as that shown in the normal group, implying the existence of halting effect. Liver also showed a slight halting effect against the decline of anti-oxidant ability, but the effect was not significant(a=0.05). A comparison between the levels of peroxide in SD rats showed that the level of TBARS in plasma increased significantly in the control group and that it was normal in the JTY group. The livers in the JTY group, compared to those in the control group, showed 36% halting effect of the normal level while their kidney's indicated the level significantly lower than the normal level. Heart's lipofuscin increased significantly in the control group, but was alike in both the JTY and the normal groups. Endurance of erythrocyte membrane(%) decreased significantly in the control group while it was kept at the similar level in both the JTY and the normal groups, indicating the halting effect. Conclusions : This study suggests that JTY is effective to defend oxidation stress caused by D-galactose in the animals. It showed that the anti-oxidant ability was maintained and strengthened. On the other hand, it reduced the level of peroxide in animals. In sum, JTY appeared to have the equilibrium normal physiological function in SD rat.
