This study was under taken to investigate the healing of Sa Gun Ja Tang extract (SE) and Sa Gun Ja Tang added Radix Astragali extract (SHE) on the artificial wound on rabbit skin. The granulation tissues were observed by microscope at the five day interval for twenty days. In order to understand the healing mechanism chick embryo culture was carried out in the presence of the extracts and the growth ratio and fusion index were counted. The results obtained were as follows: 1. The healing power of SE treated group on wound was more significant than the control group. 2. The healing power on wound was more effective at the SHE than the SE. 3. The growth ratio and fusion index were higher at the SHE treated groups than the SE treated groups. From the above result, SHE was more effective than the SE on wound healing activity by the mechanism of stimulating the cell growth ratio and fusion index.

Purpose To study the analyse radiation dose, CT number, contrast scale, image quality of the patient who needs periodic follow-up examination by applying abdominal CT using low tube voltage. Materials & Methods To evaluate the image quality of abdomen, radiation dose, CT number and contrast scale follows in change of tube voltage, subjects are divided into two groups. One group is the patients able to be applied in the clinical analysis and the other group vvere used phantom. Somatom Sensation 16(Siemens, Erlangen, Germany) was used. Twenty patient were selected at random in the group which was applied periodic follow-up examination by CT. In this clinical study, tube current was fixed in 150mA, tube voltage was adjusted according to appropriate value of each examinations and then we measured CTDI values. The measurement of CT number of each organs was performed by setting up a lcm diameter ROI at abdominal organs in the same height of first lumbar vertebra by using images of arterial phase. Quality of the abdominal images were graded into the 3 degrees by two radiologists in consensus. Abdominal shaped acrylic phantom was used in phantom study. Ion chamber was inserted into the holes located on the center and periphery of the phantom, and around there, then scaned, and radiation dose were automatically displayed by the reader which were 80kVp, 100kVp, 120kVp, 140kVp of tube voltage were applied to the phantom(diluted contrast medium with water 1:10 ratio), then the phantom was scanned and a 1cm diameter ROI in the center of the image was measured CT number. Results CTDI value was m decreased in 100kVp by 36%(11.70mGy vs 7.50mGy) in comparison with 120kVp. According to radiologist’ evaluation, there were 17 equivalent, 3 acceptable, 0 unacceptable in the group of 20 subjects. Radiation dose in the phantom study showed decreasing as tube voltage was lowered from 80kVp to 140kVp. Peripheral dose decreased by 38%, and central dose decreased by 41%. CT number showed 1365.9±4.4HU in 80kVp, 1046.1±3.7 in 100kVp, 862.8±3.2HU in 120kVp, 737.5±3.0 in 140kVp. Conclusion By applying the low tube voltage using abdominal CT to the patients who need periodical follow-up examination, the quality of the image is relatively high contrast scale without a lowering of image quality and we can decrease the effect of radiation dose.

Purpose Experiments carried out on the patients who visited this department for pulmonary disease and need CT scans for Follow-up to observe change of CT value, evaluation of image quality and decrease of radiation dose as change of tube voltage Materials and Methods Subjects were the patients of 20 persons visited this department for pulmonary disease and Somatom Sensation 16(Siemens, Erlangen, Germany) was used. Measurement of CT value as change cf tube voltage was done by setting up ROI diameter of 1cm at the height of thyroid, aortic arch, right pulmonary artery in arterial phase image using 100OkVp, measuring 3 times, and recorded the average. CT value of phantom was measured by scanning phantoms which means contrast media diluted by normal saline by various ratio with tube voltage of 80kVp, 100kVp, 120kVp, 140kVp and recorded the average of 3 CT values of center of phantom image. In analysing radiation dose, CTDIvol. values of the latest arterial phase image of 120kVp and as this research set that of 100kVp were analyzed comparatively. 2 observers graded quality of chest images by 5 degrees (UnaccepTable, Suboptimal, Adequate, Good, Excellent diagnostic quality). Results CT value of chest image increased at 100kVp by 14.06%~27.26% in each ROI than 120kVp. CT value of phantom increased as tube voltage lowered at various concentration of contrast media. CTDIbol. decreased at 100kVp(5.00mGy) by 36% than 120kVp(7.80mGy) in radiation dose analysis. here were 0 UnaccepTable, 1 Suboptimal, 3 Adequate, 10 Good, 6 Excellent diagnostic quality in totally 20 persons. Conclusion Chest CT scanning with low kilo-voltage for patients who need CT scan repeatedly can bring images valuable for diagnose, and decrease radiation dose against patients.
