The purpose of this study was to investigate the effects of modified fasting therapy using Gamrosu and herbal medicine on the changes of body compositions in women. We analyzed the medical records of 11 patients, who carried out modified fasting therapy at Dunsan Korean Medicine Hospital of Daejeon University. Body compositions (body weight, body mass index, body fat mass, skeletal muscle mass, basal metabolic rate, extracellular water ratio, abdominal circumference, thickness of abdominal subcutaneous fat, visceral fat area) were reviewed before and after modified fasting therapy. The body composition values (body weight, body mass index, body fat mass, skeletal muscle mass, basal metabolic rate, extracellular water ratio, abdominal circumference, thickness of abdominal subcutaneous fat, visceral fat area) decreased after modified fasting therapy. Results from this investigation showed that modified fasting therapy using Gamrosu and herbal medicine has positive effects on changes of body compositions.

Objectives: This study was conducted to evaluate the effects of Pueraria lobata (PL) extract onobesity related hormones in rats with estrogen deficiency. Methods: The experiments were performed with the use of ovariectomized rats asestrogen-deficient obesity rat model. They were grouped Normal (sham operation group),Control (ovariectomy group), 50 mg/kg PL (ovariectomy group+50 mg/kg of PL), 100 mg/kg PL(ovariectomy group+100 mg/kg of PL), 200 mg/kg PL (ovariectomy group+200 mg/kg of PL). PL extract was orally administered for 8 weeks once a day. Body weights and serum levels ofhormones, such as leptin, estradiol, cholecystokinin (CCK), ghrelin, and adiponectin wereestimated by ELISA. Results: PL extract significantly decreased body weight, the serum levels of leptin inestrogen-deficient obesity rats. PL extract significantly increased the serum levels of estradioland CCK. However, PL extract did not directly effect on the levels of ghrelin and adiponectin inestrogen-deficient obesity rats. Conclusions: It is concluded that PL extract reduced body weight, and regulate the hormonesrelated to energy metabolism. PL extract decreased the serum levels of leptin. PL extractincreased the serum levels of estradiol and CCK. These results indicate that PL might havepotentials for treatment of obesity and complications during the menopause caused byestrogen-deficiency. Key Words: Obesity, Pueraria

肺剔出術이 血淸電解質 및 酸鹽基平衡에 미치는 影響

白善行 中央醫學社 1967 中央醫學 Vol.12 No.6

The author investigated on the electrolyte and acid-base balance variation in dogs as effected by pentothal anesthesia, and pneumonectomy with blood transfusion or 5% dextrose infusion. The 1st group, consisting of 7 dogs, served as a control group and subjected to pentothal anesthesia the 2nd group, of 8 dogs, received pneumonectomy with blood transfusion, and the 3rd group, of 7 dogs, received the same surgical intervention with 5% dextrose infusion, with the following conclusions. 1). Intravenous pentothal anesthesia brings slight respiratory as well as metabolic acidosis. 2). Pneumonectomy under intravenous pentothal anesthesia also brings acidosis, which can be compensated slightly by the blood transfusion and 5% dextrose infusion, the former being a little more effective than the latter. 3). The blood Hb and HCO3 decrease in all groups with elevation of pCO, and regression of buffer bases as well. 4). The blood Cl- and HP04- decrease a little with the induction of anesthesia onward, which can be compensated by the blood and dextrose infusion, the formor being more effective with respect to HP04- compensation. 5). The blood Na+, K+, and Ca# decrease under anesthesia, the compensation of which can be done with the blood transfusion more effectively than the 5% dextrose infusion in pneumonectomy. In summary, anesthesia per se, essential to the surgical intervention, has a little influence over the electrolyte and acid-bass balance; and the surgical measure like pneumonectomy can also bring significant variations in the electrolyte and acid-base blance through thereduction in the concentration of blood anions and cations, It is confirmed that these variations can be compensated by the blood transfusion, while the 5 % dextrese infusionn alone can not meet the purpose leaving a serious influence in the post-operative period.

In the study we assessed the distortion of 7.0 T magnetic resonance (MR) images in reference to 1.5 T MR images in the radiosurgery of metastatic brain tumors. Radiosurgery with Gamma Knife Perfexion^® was performed for the treatment of a 54-yr-old female patient with multiple brain metastases by the co-registered images of the 7.0 T and 1.5 T magnetic resonance images (MRI). There was no significant discrepancy in the positions of anterior and posterior commissures as well as the locations of four metastatic brain tumors in the co-registered images between 7.0 T and 1.5 T MRI with better visualization of the anatomical details in 7.0 T MR images. This study demonstrates for the first time that 7.0 T MR images can be safely utilized in Perfexion^® Gamma Knife radiosurgery for the treatment of metastatic brain tumors. Furthermore 7.0 T MR images provide better visualization of brain tumors without image distortion in comparison to 1.5 T MR images.

This study investigates and analyzes the operation and ordinance status of City Architects targeting local governments in Korea. In particular, it is premised on the importance of local government ordinances to secure the stability, continuity and effectiveness of City Architect operation in the current domestic situation. As a result of the research, City Architect is operated in 76.5% of metropolitan cities and 23.9% of local governments. Among them, 67.2% of cases provided the basis for operation and set details through ordinances. In this study, definitions, qualification standards, tenure, working methods, scope of work, remuneration, work procedures, and dismissal were compared based on the City Architect ordinances. Among them, there is a difference in the existence and content of regulations on the scope of work and procedures. This study is meaningful in that it comprehensively analyzed the operation status of all local governments and the implementation of ordinances at a time when City Architect operation is spreading in Korea. Based on this analysis, it is necessary to draw important articles necessary for enactment and revision of the City Architect ordinance through detailed comparison of the content of the ordinance in the future.

We examined 36 kinds of cosmetics made in 7 different countries including white cream, message cream, lip liner cosmetic, eye liner cosmetic and pack material to investigate the content of harmful heavy metals such as arsenic, lead, cadmium and mercury in them. The results were as follows : 1. Arsenic was detected in 6 products among 36 products and the detection rate was 17%, but arsenic content of all 6 producted was under the limit value 10 ppm. 2. Lead was detected in about 56% of products, however the detection rate of massage cream and cleansing cream was 100%. Even though lead detection rate was high, the content value of Korean products was higher than that of foreign products. 3. The level of cadmium was not defined a limit value but the detection rate was 31% and the content was a level of 0.02~1.5 ppm. 4. Mercury limit value of FDA was defined as under 65 ppm in case of eye cosmetic, under 1 ppm in case of general cosmetic, bet mercury content of white cream of China product was about 618 time higher than the limit value. Among Korean products, mercury was not detected in cream and in case of lip liner cosmetic and eye liner cosmetic, The mercury content value of foreign products was higher than that of Korean products. 5. The content of heavy metal in cosmetics was a little bit higher than that in foods except fish, mussel and seaweed kinds.

The purpose of this study was to investigate 5th graders' performance for mixed operational problem. For this purpose. two kinds of studies were conducted: a descriptive study by pencil and paper tests(32 problems) and a clinical study by interviews. The conclusions drawn from the results obtained in this study were as follows: First, students were highly scored in pencil and paper tests(M=85.25%). But that score is not up to scratch. Because the problem was composed of simple calculations and if students calculate problems from only let side, they gel 75% right answer, etc. Second, most of students solved mixed operational problems by text-based way, but some students solved flexibly. There are several error types. The main error type is students' following the wrong order of calculations. Some students have obstacles to express their thought with numerical expressions. So they make errors. Third, students solve mixed operational problems with various strategies. For examples, they solve problems by describing calculation procedures, drawing lines to indicate the order of calculations, carrying out two numerical expressions, etc.
