  • Citri Reticulatae Viride Pericarpium extract(CRVP) have been used in oriental medicine for many centuries as a therapeutic agent for Soothing the liver and regulating the circulation of qi(疏肝理氣), and promoting digestion and removing stagnated food(消積化滯). The effects of CRVP on the vascular system is not known. The purpose of this Study was to investigate the effects of CRVP on the pial arterial diameter and regional cerebral blood flow(rCBF) in normal rats and ischemic cerebrovascular pathologic model rats. The changes in rCBF was determinated by Laser-Doppler Flowmetry(LDF), and the changes in pial arterial diameter were determinated by video microscopy methods and video analyzer. The results were as follows ; 1. Pial arterial diameter was significantly increased by CRVP in a dose-dependent manner. 2. Pretreatment with L-NNA significantly inhibited CRVP induced increased rCBF and pial arterial diameter. 3. Both the methylene chloride fraction and the hexane fraction of CRVP dose-dependently improved the altered cerebral hemodynamics of cerebral ischemic animal by increasing rCBF. 4. Pretreatment with L-NNA and indomethacin significantly inhibited CRVP(MC) induced increased rCBF. 5. Pretreatment with L-NNA and indomethacin significantly inhibited CRVP(hexane) induced increased rCBF. 6. Pretreatment with CRVP maredly stabilized the changes rCBF and pial arterial diameter during the period of cerebral reperusion. In conclusion, CRVP causes a diverse response of rCBF and pial arterial diameter, and CRVP dose-dependently improved the altered cerebral hemodynamics of cerebral ischemic animal by increasing rCBF and pial arterial diameter. These results suggest that the improvement of cerebral hemodynamics is also mediated by nitric oxide synthase and cyclooxygenase.

  • It is difficult to obtain a satisfactory bony union of large bone defect secondary to trauma, tumor resection, congenital pseudarthrosis of tibia and bony metaplasia following infection with conventional methods. Conventional nonvascularized autologous bone graft do not provide adequate large amounts of donor bone and usually undergo necrosis or nonunion due to lack of vascular nutrition. Currently, advanced in microsurgery have made it possible to provide a continuing circulation of blood in bone grafts so as to ensure viability. With the nutrient blood supply preserved, healing of the graft to the recipient bone is facilitated without the usual replacement of the graft by creeping substitution. Thus, the grafted bone is achieved more rapid stabilization without sacrificing viability. We reviewed 11 cases of vascularized fibular grafts which were performed from December 1982 to January 1993 and the following results were obtained: 1. Large bone defects with chronic osteomyelitis secondary to trauma were could be successfully treated by the vascularized fibular transfer. 2. In our experience, the vascularized fibular transfer was thought to be one of good methods of treatment for congenital pseudathrosis of tibia. 3. Complete tumor resection was followed by a free vascularized fibular transfer, resulting in good functional improvement, without local recurrence. Long bone defect secondary to bony dysplasia was could be reconstructed by the vascularized fibular transfer. 4. The transferred vascularized fibula had been hypertrophied with bony union during follow-up period and there was no resorption of the grafted fibula.

  • Hot spring water is underground water which naturally flows out to the earth's surface or is drilled for artificially and the water temperature should be higher than the region's average temperature for the year or underground water temperature of the earth's shallow strata of the region. Our nation stipulates that hot spring can be called if it is over $25^{\circ}C$. Generally, it is widely know that hot spring water has an effect on blood circulation, pain alleviation, soothing, and skin care and that its efficacy is mainly due to water temperature and a variety of minerals contained in water. The Onyang springs are the oldest spring district in our country and one of the most typical hot springs in this country. The current study found that there's no skin irritation through the skin irritation test applying hot spring water to cosmetic formulas, and that products using Onyang hot spring water showed an increase of 8.56% in epidermal water rate and a decrease of -67.74% in relative transepidermal water loss(TEWL), which indicates that cosmetics using Onyang hot spring water has an effecton skin improvement.

  • Menopause increases the onset of hypertension and heart disease. Whereas it increases the blood LDL-cholesterol, triglyceride and total-cholesterol levels, the HDL-cholesterol concentration is reduced. Accordingly, we examined the effect of internal organs of Todarodes pacificus (IOT) on improvement in blood flow ability and changes in serum lipid content by using ovariectomized rats. For this study, the following four groups of 9-week-old Sprague-Dawley strain female rats were evaluated over 6 weeks: normal rats (SHAM), ovariectomized rats (CON) and ovariectomized rats that were treated with IOT extracts. Ovary removal promoted platelet aggregability. However, IOT administration in the CON group after ovary excision resulted in a hinderance of coherence. The blood vessel passing time of ovariectomized rats was slower than the SHAM group. But the blood flow ability, which was slowed down for ovary removal, was improved by IOT administration. Serum triglyceride levels were significantly reduced by IOT administration. Moreover, blood HDL-cholesterol levels were reduced by ovary removal. However, IOT administration after ovary excision significantly increase HDL-cholesterol levels. The biological activity of IOT could be confirmed from these results. Moreover, IOT can be used in the development of functional foods which are meant to improve blood circulation and anti-platelet aggregation function. According to these results, we could know that IOT improved blood flow and anti-platelet aggregation. Therefore, it is expected that IOT can be used for the development of functional foods.

  • Lithospermum erythrorhizon has been known well as one of traditional medicine for fever reduction, detoxication, and blood circulation improvement. This study was carried out to isolate biological active compounds from roots of Lithospermum erythrorhizon and to investigate their low density lipoprotein (LDL) antioxidant and anticancer activities. The hexane extract of Lithospermi Radix has been separated on silica gel chromatography and a naphthoquinone pigment compound 1 has been isolated. The structure of the compound 1 has been identified by spectroscopic technique, including MS and NMR, as acetylshikonin (1). Acetylshikonin showed significantly inhibitory activity on $Cu^{2+}$-induced human LDL oxidation with $IC_{50}$ value of $8.8\;{\mu}M$ and obvious anticancer effect by inhibiting farnesyl:protein transferase (FPTase) activity with $IC_{50}$ value of $23\;{\mu}M$, which suggested that acetylshikonin might be useful for the treatment of atherosclerosis and cancer.

  • Purpose: This descriptive survey was conducted to investigate out the utilization of alternative complementary remedies for stroke patients. Method: The subject for this study were 194 patients, selected from inpatients department of 11 major medical center at Busan and Ulsan. Data were collected from August 19th to November 12th, 2002 through interview schedule designed by the investigator. Data was analyzed with frequency, percentage, and ${\chi}^2$-test by using SPSS Win 10.0. Results: 71.6% of objects has used alternative complementary remedies. The use of alternative complementary remedies according to disease-related features was statistically significant in concurrent diseases(${\chi}^2=15.03$, p=0.001), rehabilitation treatment(${\chi}^2=6.341$, p=0.012) and the level of ADL(${\chi}^2=19.63$, p=0.000). The most frequently used therapies were diet and nutrition(31.8%). The patients with less than 3month onset and in the mid-period of treatment frequently used remedies. The reason for using remedies were the belief in it's effects on treatment, but most patients responded was not effective(30.9%) or not much improvement after using remedies. Most of the patients were recommended to use remedies by their neighbors(27.3%) and family members(25.2%). The family members were most supportive in therapy(56.1%). The 28.1% of patients responded that the remedies were effective in promoting blood circulation and 95% of the patients had not experienced side effects. Conclusion: These results could be the basic material in developing nursing intervention for cerebral apoplexy patients.
