  • Postmenopausal women are at an increased risk of developing coronary artery disease, primarily due to dyslipidemia that accompanies the loss of estrogen secretion. This study was performed to investigate the effects of Opuntia humifusa seed extracts on blood flow and serum lipid level in ovariectomized rats. Twenty-eight 9-week old female Sprague-Dawley rats were randomly assigned to four groups as sham-operated rats (SHAM), ovariectomized rats (OVX-CON), and ovariectomized rats that were treated with Opuntia humifusa seed extracts (OVX-OHS 2% and OVX-OHS 6%). The diets were fed to the rats for 7 weeks after operation. Serum total cholesterol and triglyceride contents decreased in the SHAM group compared to the OVX-CON group. Seven weeks of feeding of Opuntia humifusa seed extracts resulted in significant (p<0.05) lowering of serum triglyceride and a decreasing tendency in total cholesterol levels. The level of HDL-cholesterol in serum increased significantly by feeding diets containing the 2% and 6% Opuntia humifusa seed hot-water extract (p<0.05). Blood passage times were shorter in the Opuntia humifusa seed extract-supplemented groups than in the untreated group (OVX-CON). The platelet aggregation ability was lower in groups treated with Opuntia humifusa seed extracts than in the OVX-CON group. These results suggest that Opuntia humifusa seed extracts may have benefits in improving metabolic syndrome in menopausal women.

  • Objective : Perfusion computed tomography (PCT) has the ability to measure quantitative value and produce maps of mean transit time (MTT), cerebral blood flow (CBF), and cerebral blood volume (CBV). We assessed cerebral hemodynamics by using these parameters and acetazolamide (ACZ) challenge for pre- and post-procedural evaluation in patients with unilateral cerebrovascular stenotic disease. Methods : Thirty patients underwent pre-procedural PCT with ACZ challenge, and 24 patients (80%) was conducted follow up PCT after angioplasty with same protocol. The mean MTT, CBF, and CBV were measured and compared in both middle cerebral arterial (MCA) territories before and after ACZ challenge. Hemispheric ratio and percent change after ACZ challenge were calculated before and after angioplasty. Results : The mean stenosis rate was 76.6%. Significant increases in MTT (32.6%, p=0.000) and significant decreases in CBF (-14.2%, p=0.000) were found in stenotic side MCA territories. After ACZ challenge, there were significant changes in MTT (37.4%, p=0.000), CBF (-13.1%, p=0.000), and CBV (-10.5%, p=0.001) in pre-procedural perfusion study. However, no significant increases were found in MTT, or decreases in CBF and CBV in post-procedural study. There were no significant changes after ACZ challenge also. In addition, the degrees of these changes (before and after ACZ challenge) were highly correlated with the stenotic degrees in pre-procedural perfusion study. Conclusion : PCT with ACZ challenge appears to be a useful tool to assess the cerebral perfusion status especially in patients with unilateral symptomatic stenotic disease.

  • Background The aim of this study was to collect important data on the time of oxygen saturation change in relation to skin flap color alteration using non-invasive pulse oximetry to evaluate its ability to provide continuous monitoring of skin flap perfusion. Methods An experimental study on the monitoring of blood perfusion of 20 tube-island groin flaps of 10 male New Zealand rabbits was performed using pulse oximetry. The animals were randomly assigned to one of two groups representing a blockage of either arterial or venous blood flow. The oxygen saturation change and clinical color alteration were monitored from the beginning of vessel clamping until the saturation became undetectable. The result was analyzed by the t-test using SSPS ver. 10.0. Results The mean times from the vessel clamping until the saturation became undetectable were $20.19{\pm}2.13$ seconds and $74.91{\pm}10.57$ seconds for the artery and vein clamping groups, respectively. The mean time of the clinical alteration from the beginning of vein clamping was $34.5{\pm}11.72$ minutes, while the alteration in flaps with artery clamping could not be detected until 2.5 hours after clamping. Conclusions The use of neonate-type reusable flex sensor-pulse oximetry is objective and effective in early detection of arterial and vein blockage. It provides real-time data on vessel occlusion, which in turn will allow for early salvaging. The detection periods of both arterial occlusion and venous congestion are much earlier than the color alteration one may encounter clinically.

  • Breast cancer is the most commonly diagnosed cancer in women in the world and is one of the leading causes of death due to cancer. Health benefits have been linked to additive and synergistic combinations of phytochemicals in fruits and vegetables. Nigella sativa has been shown to possess anti-carcinogenic activity, inhibiting growth of several cancer cell lines in vitro. However, the molecular mechanisms of the anti-cancer properties of Nigella sativa phytochemical extracts have not been completely understood. Our data showed that Nigella sativa extracts significantly inhibited human breast cancer MDA-MB-231 cell proliferation at doses of $2.5-5{\mu}g/mL$ (P<0.05). Apoptotic induction in MDA-MB-231 cells was observed in a dose-dependent manner after exposure to Nigella sativa extracts for 48 h. Real time PCR and flow cytometry analyses suggested that Nigella sativa extracts possess the ability to suppress the proliferation of human breast cancer cells through induction of apoptosis.

  • The purpose of this study was to review of mechanism and application methodology about mental practice. The mental practice is symbolic rehearsal of physical activity in the absence of any gross muscular movements. Human have the ability to generate mental correlates of perceptual and motor events without any triggering external stimulus, a function known as imagery, Practice produces both internal and external sensory consequences which are thought to be essential for learning to occur, It is for this reason that mental practice, rehearsal of skill in imagination rather than by overt physical activity, has intrigued theorists, especially those interested in cognitive process. Several studies in sport psychology have shown that mental practice can be effective in optimizing the execution of movements in athletes and help novice learner in the incremental acquisition of new skilled behaviors. There are many theories of mental practice for explaining the positive effect In skill learning and performance. Most tenable theories are symbolic learning theory, psyconeuromuscular theory, Paivio's theory, regional cerebral blood flow theory, motivation theory, modeling theory, mental and muscle movement nodes theory, insight theory, selective attention theory, and attention-arousal set theory etc.. The factors for influencing to effects of mental practice are application form, application period, time for length of the mental practice, number of repetition, existence of physical practice.

  • Objectives : Meridian Scraping Therapy(MST: Kwal-Sa: 刮痧) has not well known in Korea. But it's a kind of Traditional Physical Therapy wide spreaded in China and Taiwan. So I want to introduce this new Therapy by summarizing the basic theories and practical manipulations. Conclusions : To analyse the meaning of the character Kwal-Sa, Kwal(刮) means scraping the skin by some tools and Sa(痧) means originally the red spots on skin of measles but in this therapy it's the red spot on skin after the treatment. Meridian Scraping Therapy is based on the meridiology and holism which are the basic theory of Oriental Medicine. The main effects of Meridian Scraping Therapy are draining of pathogenic factors, promoring the flow of ki and blood, tonify yang, balancing the harmony of intemal organs and enhancing the immuno-ability in body. Rhinoceros corpus is common matrial of MST-plate which is the tool of manipulation. And by this plate several manipulation is performed according to the symptom and the locations of pain. The merits of MST are that easily learned by practician, the effects of the treatment are very quickly manifest and no significant side-effects. And additionally this therapy performed not only for treat diseases but prevent it and preserve health.

  • Estrogen deficiency in peri- and postmenopausal women results in variety of neurovegetative, psychic and somatic symptoms, and may contribute to severe diseases within the aged female population. Ecklonia stolonifera (ES) is an edible brown algae traditionally used in fishery towns in Far East Asia. This study was performed to investigate the effects of ES extracts on blood flow and serum lipid concentration in ovariectomized rats. Weight-matched female Sprague-Dawley strain rats were assigned to four groups. Three groups were surgically ovariectomized (OVX). The fourth group was sham operated. Rats were randomly assigned to the following groups: sham-operated rats (Sham), ovariectomized control rats (OVX-CON), ovariectomized rats supplemented with ES extract at 50 mg/kg bw/day (OVX-ES50) and ovariectomized rats supplemented with ES extract at 200 mg/kg bw/day (OVX-ES200). Serum total cholesterol and triglyceride contents decreased in the sham group compared to the OVX-CON group. Six weeks feeding of ES extract resulted in a significant (p<0.05) lowering of serum triglyceride and a lowering tendency of total cholesterol level. The level of Hdl-cholesterol in serum increased by supplementation of ES extracts at 50 mg/kg and 200 mg/kg bw/day (p<0.05). Blood passage time of the ES extracts-supplemented group was higher than the OVX-CON group. The ability of platelet aggregation of groups treated with ES extracts was less than that of the OVX-CON group. These results suggest that the beneficial effects of ES extract may be used to possibly improve on the metabolic syndrome of menopausal women.

  • The purpose of this study was to investigate the effects of the Bambusae Caulis in liquamen (BCL) on blood circulation in animal models. Previous studies on BCL have shown effects on thrombolytic activity and angiotensin-converting enzyme (ACE) inhibitory activity. In the mouse model, the triglyceride content were 301.5 mg/dL in the high fat diet+BCL II 0.01% group, 289.2 mg/dL in the high fat diet+BCL II 0.05% group, which was significantly lower than the high fat diet group. The total cholesterol content was 311.9 mg/dL in high fat diet+BCL II 0.01% and 293.7 mg/dL in high fat diet+BCL II 0.01% 0.05%, respectively, which was significantly lower than the high fat diet group. The HDL-cholesterol level was 206.0 mg/dL for the high fat diet, 196.6 mg/dL for the high fat diet+BCL II, and 189.2 mg/dL for the high fat diet+BCL II. There was no significant difference between the 0.01% and 0.05% groups. The high-fat diet+0.05% group was significantly improved in the blood flow compare to the high fat diet and the high fat diet+0.01% group. Platelet aggregation inhibition ability was inhibited in the high fat diet+0.01% and 0.05% groups compared to the high fat diet group.

  • The more the population grow, the severer the shortage of a basic human needs such as clean water, food, energy resources and so on. Recently, we aware that deep sea water can be utilized to solve comprehensively food, energy and water problems. In this study, inhibitory effect of the deep sea water of east coast (DSW) on platelet aggregation were investigated using washed platelet and beneficial effect of the change of lipid concentration on serum at various time intervals for three weeks. In this study six groups of 6-month-old Sparague-Dawley rats were examined. An intact group served as controls (C-1D : breeding for one day, C-1W : breeding for one week, C-3W : breeding for three week). The fourth group (1D-DSW) supplemented with DSW for one day. The fifth group (1W-DSW)supplemented with DSW for a week. The sixth group (3W-DSW)supplemented with DSW for three weeks. The total cholesterol and triglyceride concentration on serum of supplemented groups with the DSW for one or three weeks were significantly decreased. The serum HDL-cholesterol level in the DSW groups were significantly higher than the level in the control group. The supplementation of DSW for one day did not appear to have such a beneficial effect on lipid level. The ability of platelet aggregation of supplemented groups with DSW was less than control group. These results suggest that supplementation with DSW is positively influence on lipid concentration and platelet aggregation.
