This study investigated the effects of nursing in formation given verbally and a booklet on the knowledge, Physical symptoms, anxiety and daily activities of patients recovering from open heart surgery from just before discharge to six weeks after discharge. The convenience sample was of patients who had undergone open heart surgery in Seoul National University Hospital. The first 25 patients who agreed to participate in the study became the control group. They did not receive the intentional information but the usual nursing care. The next 28 patients became the experimental group who received a booklet about their post-discharge care which was discussed with them by the researcher before discharge. This study used a non equivalent control group non - synchronized quasiexperimental design. The tools included a 30 item knowledge scale, a 9 item physical symptom scale, Spielberger's state anxiety scale, and a 28 item daily activity scale. The instruments were applied before discharge and at two and six weeks after discharge. For data analysis, frequency, t-test, Pearson's Correlational Coefficient and Cronbach's $\alpha$ were used. The results were as follows : 1. Information given through the booklet was effective in increasing the knowledge of patients recovering from open heart surgery. The experimental group's knowledge was higher at 2 weeks after discharge than prior to discharge (P＜0.05). 2. There was no significant difference in physical symptoms between the two groups at two and six weeks after discharge. 3. Information given through the booklet was effective in decreasing the State Anxiety two weeks after discharge (P＜0.001) but at six weeks after discharge, there was no significant difference in anxiety between the control and the experimental groups. 4. There was no significant difference in daily activity between the two groups at two and six weeks after discharge. 5. There was a negative correlation between knowledge at discharge and at 2 weeks and anxiety at 2 weeks after discharge. There was a positive correlation between knowledge at discharge and daily activity at 2 weeks after discharge. There was a negative correlation between knowledge at 2 weeks and Physical symptom at 6 weeks after discharge.

The purpose of this investigation was to examine the effects of osteocalcin (serum bone GLA-protein, BGP) and procollagen carboxy-terminal propeptide (PICP) on new bone formation of canine fracture models. Serum osteocalcin and PICP were measured by standard RIA. The values of osteocalcin and PICP in the non-union and delayed-union fracture models were measured biweekly for 20 weeks in 14 dogs. The unions were radiographed for fracture healing. In non-union fracture group, the activity of BGP was markedly increased at four to eight weeks and decreased at twelve to twenty weeks and the activity of PICP was markedly increased at two to six weeks and slightly decreased at sixteen to twenty weeks. In delayed-union fracture group, the activity of BGP was markedly increased at two to eight weeks after treatment and maintained for the level until twenty weeks and the activity of PICP was markedly increased at two to six weeks after treatment and maintained for the level until twenty weeks. Radiologically, non-union group was not achieved until twenty weeks after fracture, delayed-union group was successfully achieved in eighteen weeks after fracture. These results suggested that the. activities of osteocalcin and PICP are useful parameters for biochemical markers of bone formation in dogs.

This study was conducted for 39 patients who are recipients of allogeneic hemopoietic stem cell transplantation at BMT ward of St. Mary's hospital affiliated to Catholic University of Korea from April to September 1999. The subjects were devided into two groups; those who received both TEl and chemo therapy as conditioning regimen (TEl group). and those who used chemo agents as singular conditioning regimen (chemo group). The oral intake status of the two groups were compared through physical assessment and blood chemistry exam of the subjects, and factors influencing their nutritional change and oral intake were explored in each stage of the transplantation (six stages: admission, conditional stage, date of transplantation, one week after transplantation, two weeks after transplantation, and three weeks after transplantation). The prior aim of the study was to provide baseline data to minimize delayed treatment from nutritional deficiency of the subjects. The results were as follows: 1. TBI group was significantly decreased of oral calorie intake in two weeks after transplantation compared to admission and conditioning stage while that of chemo group was significantly decreased on the date of transplantation. 2. TBI group was significantly decreased of protein intake in two weeks after transplantation compared to admission and conditioning stage. In chemo group, protein intake was significantly decreased on the date of transplantation compared to admission. It was remarkable that TBI group showed lesser protein intake than chemo group. 3. Both group were significantly decreased of BMI in one week and three weeks after transplantation compared to admission. TBI group showed significantly higher BMI than chemo group. 4. Both group were significantly decreased of Triceps Skinfold Thickness (TST)on the date of transplantation compared to admission stage. 5. TBI group was significantly decreased of mid-arm muscle circumference (MAMC) in two weeks after transplantation compared to admission, conditioning, date of transplantation. 6. TBI group was significantly decreased of albumin level in two weeks after transplantation compared admission stage. In chemo group, it was significantly decreased on the date of transplantation compared to admission, three weeks after the transplantation. 7. TBI group was significantly decreased of transferrin level in two weeks after transplantation compared admission, conditioning, date of transplantation and one week after transplantation. In chemo group, it was decreased of transferrin level in 3 weeks after transplantation. 8. Oral intake of TEl group was impacted by vomiting before transplantation and gingivitis after transplantation. In chemo group, it was impacted by vomiting before transplantation and by two factors, gingivitis and nausea, after transplantation. The results showed oral calorie intake was not different between the two groups while protein intake was significantly lower in TBI group than chemo group. Oral intake was significantly impacted by vomiting before transplantation in both groups, but affected by oral gingivitis in TBI group and gingivitis and nausea in chemo group after transplantation. This findings present that standardized strategies to manage nutrition and gingivitis more effectively are desperately needed to enhance oral intake and protein intake of patients who receive TBI as conditioning regimen.

3-weeks old Commelina was transferred to and grown in Hoagland solution ($\pm$ 100 $\mu{M}$ $Cd^{2+}$, 100 $\mu{M}$ $Cd^{2+}$ ＋ 100$\mu{M}$ $Ca^{2+}$, 100 $\mu{M}$ $Cd^{2+}$ ＋ 200 $\mu{M}$ EGTA) for two weeks and then a number of physiological activities was investigated. $Cd^{2+}$ reduced total chlorophyll content up to 29% at a week and 75% at two weeks. In the treatment of $Cd^{2+}$ ＋ $Ca^{2+}$, the total chlorophyll content was reduced to 29% at a week and 80% at two weeks. $Cd^{2+}$ reduced 24% of Fv/Fm after two weeks. In case of $Cd^{2+}$ ＋ $Ca^{2+}$, Fv/Fm was reduced 55% at a week, but after two weeks, the plants were almost dead and Fv/Fm could not be measured. When EGTA was treated with $Cd^{2+}$, the value of Fv/Fm was not affected. There were no differences of water potential between the control and the treatment of $Cd^{2+}$+EGTA toy a week, but in other treatments. water potential was reduced. $Cd^{2+}$ reduced about 21% of water potential and $Cd^{2+}$ ＋ $Ca^{2+}$ reduced 43% of water potential after two weeks. $Cd^{2+}$ inhibited 21% of photosynthetic activity at a week and 32% at two weeks. In case of photosynthetic activity, $Cd^{2+}$ ＋ $Ca^{2+}$ inhibited 58% at a week and 73% at two weeks. $Cd^{2+}$+EGTA inhibited 15% of photosynthetic activity at a week and 21% at two weeks. Similar results were found in stomatal conductance. From the above results, it was observed that the treatment of $Ca^{2+}$ with $Cd^{2+}$ induced more reduction of a series of physiological responses than those of the treatment of $Cd^{2+}$ alone. Therefore, it could be concluded that $Ca^{2+}$ did not reduce the toxicity of $Cd^{2+}$, but enhanced $Cd^{2+}$ -induced physiological toxicities, but EGTA induced an decrease of $Cd^{2+}$ -induced physiological toxicities.

The purpose of this study was to compare the effects of respiratory exercise on cardiopulmonary function and muscle activity of rectus abdominis in smokers and non-smokers with elderly people. All the participants were older than 65 years, and twenty non-smokers, and twenty smokers participated. Non-smokers and smokers were randomly divined into 10 feedback breathing exercises (FBE) and a balloon-blowing exercise (BBE) group. The FBE and the BBE were performed three times a week for four weeks. Forced vital capacity (FVC), forced expiratory volume at one second (FEV1), forced expiratory volume at one second/forced vital capacity (FEV1/FVC), peak expiratory flow (PEF), and vital capacity (VC) were measured as pulmonary function. EMG was used to measure the activity of the rectus abdominis. In the FBE and BBE groups, $FEV_1$ was significantly lower in non-smokers compared to smokers at two and four weeks (p<.05), $FEV_1/FVC$, PEF and VC were significantly lower in non-smokers compared to smokers to pre-test, two weeks, four weeks and six weeks (p<.05). Muscle activity of rectus abdominis was significantly difference in the BBE group at pre-test, two weeks, four weeks, and six weeks (p<.05). These results suggest that respiratory exercise was effective in improving pulmonary function and rectus muscle activity.

Objectives: This study is designed to evaluate the mechanical stability of orthodontic mini-implants with vertical grooves in rabbits. Materials and Methods: This study was done from March 2011 to February 2012 in Dental Research Institute of Seoul National University. Thirty-two mini-implants in the control group and 32 in the rotation bump (RB) group were inserted in the tibias of 16 rabbits and were removed after two weeks and four weeks, respectively. The maximum insertion torque (MIT), maximum removal torque (MRT), torque ratio (TR) of MRT to MIT and removal angular momentum (RAM) were all measured at the time of removal. Results: There were no significant differences between the two groups in MIT and MRT at two weeks or four weeks. However, TR and RAM at four weeks in the RB group were significantly higher than in the control group (P<0.05). TR of the RB group was significantly increased at four weeks (P<0.05). In both groups, RAM at four weeks was significantly higher than at two weeks (P<0.05). Conclusion: These results suggest that RB of the mini-implant could provide resistance to the removal rotation, although it did not increase the MRT.

Objectives: This study was performed to assay the effect of neodymium oxide on the generation of reactive oxygen species and DNA oxidative damage by intratracheal instillation. Methods: Two groups of rats were exposed to neodymium oxide($Nd_2O_3$) via intratracheal instillation with doses of 0.5 mg and 2.0 mg, respectively. At two days and at 12 weeks after exposure, the contents of neodymium oxide in the lung, liver, kidney, heart and brain, leukocyte, olive tail moment, ROS, RNS, lactate dehydrogenase, albumin, cytokine and MDA from BALF were measured. Results: Neodymium oxide contents in the liver, kidney, heart, and brain were detected at less than $1{\mu}g/g$ tissue concentration. However, in the lungs at four weeks the highest amount were detected and then found to be drastically reduced at 12 weeks. ROS and RNS in bronchoalveolar lavage increased in concentration dependently at two days, four weeks and 12 weeks after neodymium oxide instillation. However, ROS and RNS decreased with the passage of time. At two days the total number of WBC in BALF in the high concentration group was significantly increased, and at four weeks the total number of WBC were significantly increased in the low and high concentration groups(p<0.01). At two days after exposure, the LDH of the low and high concentration groups was significantly increased. At 12 weeks, only the LDH of the high concentration group was significantly increased compared to in the control group(p<0.01). As a result of Comet assay, after two days, damage to the DNA of the low and high concentration groups was observed. Conclusions: Intratracheal instillation of neodymium oxide induces the generation of ROS and DNA damage in rats.
