  • Much attention has been given to the role of safflower (Carthamus tinctorius L.) seed in preventing and treating osteroporosis recently. Although numerous studies were done on effects of safflower oil, no attention was given to the role of dietary fiber of safflower seeds. This study was aimed at investigating physiological significance of defatted safflower seed as a source of dietary fiber. Sprague Dawley female rats were assigned one of 5 groups: ovariectomized control (Ovx-control) group and ovariectomized rats 15% (Ovx-ss15) and 30% defatted safflower seed (Ovx-SS30), sham-operated (Sham) group and a normal group. Cholesterol was supplemented to all diets at 0.5% except the normal diet. Ovariectomized rats were pair-fed isocalorically to the Sham group. Ovariectomy caused heavier body weight, but feeding 30% safflower seed brought back to the level of Sham group. Activities of disaccharidases of jejunal mucosa were significantly lowered in Ovx-control group compared to those of Sham, and supplementation of safflower seed tended to increase the activities. Fecal weight of Ovx-SS15 and Ovx-SS30 were almost twice as those of Ovx-control Sham. Propionic acid and butyric acid concentrations per g of feces of Ovx-SS15 and daily excretion of these fatty acids were significantly increased as compared to those of Sham and Ovx-control. In concentration defatted safflower seed supplementation significantly increased fecal bulk and short chain fatty acid production in large intestine of rats.

  • Purpose : The purpose of the present study is to report the effect of proprioception of ankle after kinesiotaping application on ankle. Method : This study has conducted to target 30 average adult subjects with no damage to the ankle joint (16 males and 14 females). The group is divided into experimental group and sham groups in random way. The subjects in the experimental group are applied taping kinesiology on ankle joint. The subjects in the sham group are applied a sham taping on the ankle joint which is not actually affected for real ankle joint problem. Each subjects in both groups has tree trials in plantarflexion, dorsiflexion, inversion, and eversion before and after application of the kinesiotaping or sham taping of the bare footed ankle. The outcome were determined from the difference between the target angle and the trial angle produced by the subject. Results : These results from the experiment shows that the experimental group compared to the difference in kinesiotaping angle values were significantly different from each dorsiflexion (DF), eversion (EV) (p<.05). Otherwise, in the sham group did not produce significant differences in any joint movement. In addition, when we compared between two groups (the experimental and sham groups), it did not show that there was significant differences. Conclusion : First, there is no significant difference between the sham group and kinesiotaping group after proprioceptive tests. Second, even though there is no significant outcome in statistical analysis, there is actual differences in the experiment. This result might be ceiling effect, and if the kinesiotaping were applied to actual ankle injury patients, this taping treatment could be very effective for curing this patient.

  • 본 연구는 수영운동이 백색지방조직의 혈관신생을 조절함으로써 비만을 개선하는지를 조사하였다. 고지방식이를 섭취한 암컷 쥐는 모의 수술 군(Sham), 난소절제 수술 군(OVX) 및 수영운동을 실시한 난소절제 군(OVX + Swim)으로 나뉘었다. Sham에 비해 OVX는 몸무게, 지방조직무게 및 지방세포의 크기가 증가 되었다. 그러나 OVX + Swim의 이러한 요소들(: 몸무게, 지방조직무게 및 지방세포의 크기)은 OVX에 비해 감소 되었다. Sham에 비해 OVX는 백색지방조직에서 혈관신생 촉진인자와 MMPs의 유전자 발현이 증가하였고, 혈관신생 억제인자들의 유전자 발현은 감소하였다. 그러나 OVX + Swim은 OVX에 비해 백색지방조직에서 혈관신생 촉진인자와 MMPs의 유전자 발현이 감소하였고, 혈관신생 억제인자들의 유전자 발현은 증가하였다. 이러한 연구결과들은 고지방식이를 섭취한 난소절제 암컷 쥐에서 수영운동이 백색지방조직의 혈관신생을 억제함으로써 비만을 개선한다는 것을 제시하였다.

  • 본 연구에서는 16주령 암컷 흰쥐를 대상으로 이소플라본의 함량이 다른 세 종류의 식이를 6주간 공급한 후 뇨와 변에서 daidzein과 genistein의 배설량을 측정하여 생체 이용성을 살펴보고 난소절제 여부에 따른 차이가 있는지도 알아보고자 하였다. 식이 내 이소플라본의 첨가량이 많을수록 변 중 daidzein 배설량은 유의적으로 증가하여 섭취량에 따른 반응의존성을 나타내었다. 그러나 난소절제여부에 따른 차이는 없었다. 변 중 genistein의 배설량도 이 소플라본의 첨가량이 많을수록 유의적으로 증가하였으나, HI군에서 비교해보면 난소절제시 sham수술보다 변 중 배설량이 유의적으로 낮았다. 변 중 회수율의 경우에는 배설량과 같은 섭취량에 비례적인 관계는 나타나지 않았으며 난소절제 여부에 따른 차이도 뚜렷하지 않았다. 뇨 중 daidzein의 배설량은 변 중 배설량과 마찬가지로 sham과 난소절제 모두에서 이소플라본의 첨가량이 많을수록 유의적으로 증가되었다. 난소절제 여부에 따른 뇨 중 이소플라본의 배설량을 보면 LI, MI, HI군에서 daidEein의 배설량은 sham에 비해 난소절제에서 유의적으로 낮았으며 genistein의 배설량도 LI군에서는 유의적으로 낮았다. 또한 뇨 중 회수율을 보면 sham에서 LI군에 비해 Ml와 Hl군에서 회수율이 유의적으로 낮았는데, 난소절제의 경우에는 이소플라본의 수준에 따른 회수율의 차이가 없었다. 그리고 회수율은 난소절제에서 sham에 비해 LI와 MI군에서 유의적으로 낮았다. 그러므로 이소플라본의 섭취수준이 증가하면 뇨와 변을 통한 이소플라본의 배설은 한국인의 일상적 섭취수준의 10배 범위에서는 섭취량에 의존적임을 알 수 있으며, 난소절제를 하였을 경우 뇨와 변을 통한 배설량을 감소시켜서 더 많이 체내에서 이용함을 알 수 있었다. 섭취량이 증가하면 sham수술의 경우에는 뇨 중 회수율이 감소함에 비해 난소절제에서는 회수율이 동일하고 LI와 MI군에서는 유의적으로 sham에 비해 회수율이 낮으므로 난소절제모델에서는 이소플라본의 생체이용성이 매우 높음을 확인할 수 있었다. 이러한 점으로 미루어볼 때 난소호르몬의 분비가 없는 폐경 후 여성에게는 이소플라본의 섭취가 호르몬으로서의 효과가 뚜렷할 것으로 짐작되며 이소플라본의 보충섭취를 권장한다.

  • Objectives : This study aimed to review randomized controlled trials of acupuncture performed in South Korea that used sham acupuncture as a control group. Methods : The following databases were searched through the end of September 2011: Koreanstudies information service system (KISS), Korean medical database (KMbase), national discovery OR science leaders (NDSL), oriental medicine advance searching integrated system (OASIS), and research information service system (RISS). The following search terms were used: acupuncture AND (sham or placebo). The reference lists of searched articles and Korea institute of oriental medicine (KIOM) reports(2005~2009) were identified. The following data were extracted: year/first author, disease, number of participants, blinding, intervention, outcome, and result. Where appropriate, we performed meta-analysis. The methodological quality was assessed according to the Jadad scale and 'risk of bias' by Cochrane Handbook procedure. Results : Twenty-nine studies were included in this review. In eighteen studies, penetrating sham controls were used as the control intervention, whereas the remaining eleven studies adopted non-penetrating sham controls such as the Park Sham Device or blunt auricular acupuncture. Nine studies showed statistically significant difference in outcomes. Twelve studies concerning insomnia after stroke, chronic tension-type headache, idiopathic Parkinson's disease, Hwa-Byung, and smoking cessation were included in meta-analysis. A meta-analysis of insomnia after stroke only found significant difference(MD -4.31, 95% Cl -6.19 to -2.42, $p$<0.00001). In general, all of the studies showed low methodological quality(Jadad score: mean 2.1). Risk of bias by Cochrane Handbook procedure varied. Conclusions : The results of this study could not suggest conclusive evidence that acupuncture is more effective than sham acupuncture in several diseases. In the future, more studies with rigorous acupuncture trials using sham controls should be conducted.

  • The effects of Sahyangsohapwon on the enhancement of learning and memory of AD model rats were studied with Morris water maze and radial arm maze. Sample group was electrolytically lesioned on nbM, and then daily treated with the medicine for two months. Control group with nbM lesion, and sham group with the sham operation were treated the vehicle for same duration. The following results were observed. In the learning trials of Morris water maze, all three groups were improved in learning capacity as trials were repeated, but the sham group showed more prominent improvement in learning compared with the control group(p<0.01). 2. In memory retention test of Morris water maze, the sham group marked more significant improvement statistically in memory retention compared with the control group(p<0.05). 3. In the learning of radial arm maze, the sham group shows better learning capacity significantly compared with the control group(p<0.05). With the experimental results above, Sahyangsohapwon can be supposed to have the improving effects on the learning and memory of AD rats induced by electronical injury of nbM.

  • The purpose of this research was to investigate the effect of the boron supplementation on lipid profiles and antioxidant capacities in ovariectomized (OVX) rats. Rats were divided into 3 groups and fed diet with intake levels of boron (0.5 ppm,50 ppm,100 ppm) for 4 weeks. The half of rats in each group was ovariectomized and the others were sham-operated. And rats were fed same diets for 8 weeks after operation. Feed intake and weight gain were significantly increased by increasing boron intake and higher in OVX group than those in sham-operated. FER was significantly higher in OVX group than that of sham-operated. There were no significant differences in serum lipid profiles among the groups. The contents of hepatic total lipid were significantly higher in OVX group than those of sham-operated and the lowest in high-boron group. Hepatic GST activity was significantly decreased by ovariectomy and the lowest in very high-boron group. Hepatic catalase activity was the lowest in high-boron group of OVX. Hepatic TBARS level of high-boron group was the lowest in sham-operated groups. Hepatic TBARS level induced by AAPH was significantly decreased by increasement of boron supplementation. Taken together, this results suggest that the boron supplementation have the potential role for improving lipid profiles and antioxidant capacities in OVX rats.

  • This study examined the effect of dietary lipids and ovariectomy(OVX) on bone mass in rats. The experimental animals were divided into sham operation(S) or OVX(O) groups and then each group was divided into soybean oil(SS, OS), beef tallow(SB, OB), and fish oil(SF, OF) diet group. Experimental diets were fed for 16 weeks. Weight gain tended to be higher in OVX groups than in sham groups. Weigth gain was the highest in beef tallow group (SB) and the lowest in fish oil group(SF). There were no difference in weight, length, breaking force, strength and circumference of femur mong groups. However, volume of femur tended to be higher in OVX groups than in sham groups. Ash content of femur was significantly lower in OVX than sham groups but there were no difference between SB and OB group. Ca content in the soybean oil and beef tallow group were not influenced by OVX but Ca content in fish oil group was significantly higher in OF than SF group. The SB group showed the hyighest Ca content and the SF group showed the lowest Ca content. P content of femur was significantly lower in OVX groups than in sham groups but there were no difference between SB and OB group. The SS group showed the highest P content and the OS and OF group showed lower P content compare to other groups. From this result, it suggested that beef tallow positively influenced maintenance of bone mass by means of accumulation of body fat in ovariectomy.

  • Purpose: The purpose of this study was to identify the effects of hand acupuncture therapy on sleep quality by means of a sleep questionnaire, polysomnography and a cerebral blood flow test in $30{\sim}59$ year old adults. Methods: The study was a sham controlled design. Twenty-two adults were assigned to the pellet stimulating group (11) or sham group (11). The pellet stimulating group received hand acupuncture therapy using New Seoam Press Pellets number 1 for 4 weeks. On the other hand, the sham group used the same Adhesive tape in terms of shape, size and quality as New Seoam Press Pellets number 1 for 4 weeks. A Transcranial Doppler Ultrasonography and Carotid Duplex Ultrasonography examination were used for evaluating cerebral blood flow. Data was analyzed using the SPSS 12.0 version program with $X^2-test$, Fisher's exact test and Mann Whitney U-test. Results: In the pellet stimulating group, subjective sleep quality significantly improved more than that of the sham group. Among the sleep indices of the polysomnography, total sleep time and sleep latency of the sham group significantly improved. The cerebral blood flow test didn't show any differences. Conclusion: These results suggest that hand acupuncture therapy is effective for subjective sleep improvement only, not polysomnographical sleep indices and cerebral blood flow.

  • Recently, there is an increasing nationwide concern in Korea that exposure to electric and magnetic fields in the home environment may not be safe in humans. To identify possible effects of horizontally polarized magnetic fields (MF) exposure on embryo-fetal development, timed-mated female Sprague-Dawley rats (24/group) received continuous exposure to 60 Hz MF at field strengths of 0 Gauss (sham control), 50mG,833 mG, or 5000 mG. Dams received MF of sham exposures for 22hr/day on gestation days 6 through 20. Experimentally generated MF were monitored continuously througout the study. There was no evidence of maternal toxicity of developmental toxicity in any MF-exposed groups. Mean maternal body weight, organ weights, and gross findings in groups exposed to MF did not differ from those in sham control. No significant differences in fetal deaths, fetal body weight, and placental weight were observed between MF-exposed groups and sham control. External, visceral, and skeletal examination of fetuses demonstrated no significant differences in the incidence of fetal malformations between MF-exposed and sham control groups. In conclusion, exposure of pregnant Sprague-Dawley rats to 60 Hz at MF strengths up to 5000 mG during gestation day 6-20 did not produce any biologically significant effect in either dams of fetuses.
