Objective : In recent years, many investigators have questioned whether the analgesic effect of acupuncture is simply related to the stress-induced analgesia (SIA). However, there has been lack of studies on this issue. In this study, the stress levels induced by manual acupunctures are compared with the stress in animal experiment models. The experiments have been carried out with Sprague Dawley (SD) rats. Method : For stress level evaluation, Hot plate test has been used. Maximum Possible Effect (MPE) has been measured by checking the pre-test time and post-test time. Cortisol and corticosterone concentrations in serum were measured by enzyme-linked immunosorbent assay (ELISA). Results : In the hot plate test, MPE values of post-test time were significantly decreased after 10 minutes than after 5 minutes. Therefore, optimal time interval was chosen as 10 minutes. There was significant difference of MPE values between Suspension group and all other treatment groups. However, there were no significant differences of MPE values between Sham group and all other treatment groups. However, MPE values showed tendency to decrease when acupuncture needle diameter increased. MPE values of ST040, ST040(lido), NAP040(lido) groups were markedly decreased than that of Suspension group, while that of NAP040 group was substantially increased than that of Sham group increased in acupoint and nonacupoint models. Serum cortisol concentrations of treatment groups were not significantly different from that of Suspension and Sham groups. Serum corticosterone concentration of 0.25 mm group was substantially increased than that of compared with Sham group. Serum cortisol and corticosterone concentrations of treatment groups were not significantly different from those of Suspension and Sham groups in acupoint and nonacupoint models. Conclusion : From hot plate test and serum stress hormones concentrations, it is found that manual acupuncture treatment induces negligible stress or SIA on ST36. And the stress induced by manual acupuncture is more closely related to acupuncture point needlings than diameters of acupuncture needles.

Background: This study was conducted to provide a comparison between the clinical outcomes of primary percutaneous coronary intervention (PCI) and that of fibrinolysis followed by routine invasive treatment in ST elevation myocardial infarction (STEMI). Methods: A total of 184 consecutive STEMI patients who underwent primary PCI or fibrinolysis followed by a routine invasive therapy were enrolled from 2004 to 2011, and their major adverse cardiovascular events (MACEs) were compared. Results: Among the 184 patients, 146 patients received primary PCI and 38 patients received fibrinolysis. The baseline clinical characteristics were similar between both groups, except for triglyceride level ($68.1{\pm}66.62$ vs. $141.6{\pm}154.3mg/dL$, p=0.007) and high density lipoprotein level ($44.6{\pm}10.3$ vs. $39.5{\pm}8.1mg/dL$, p=0.005). The initial creatine kinase-MB level was higher in the primary PCI group ($71.5{\pm}114.2$ vs. $35.9{\pm}59.9ng/mL$, p=0.010). The proportion of pre-thrombolysis in MI 0 to 2 flow lesions (92.9% vs. 73.0%, p<0.001) was higher and glycoprotein IIb/IIIa inhibitors were administered more frequently in the primary PCI group. There was no difference in the 12-month clinical outcomes, including all-cause mortality (9.9% vs. 8.8%, p=0.896), cardiac death (7.8% vs. 5.9%, p=0.845), non-fatal MI (1.4% vs. 2.9%, p=0.539), target lesion revascularization (5.7% vs. 2.9%, p=0.517), and stroke (0% vs. 0%). The MACEs free survival rate was similar for both groups (odds ratio, 0.792; 95% confidence interval, 0.317-1.980; p=0.618). The clinical outcome of thrombolysis was not inferior, even when compared with primary PCI performed within 90 minutes. Conclusion: Early fibrinolysis with optimal antiplatelet and antithrombotic therapy followed by appropriate invasive procedure would be a comparable alternative to treatment of MI, especially in cases of shorter-symptom-to-door time.

Alcaligenes eutrophus was successfully recovered from high cell density broth by pre-treatment with Fe-based coagulants. An inorganic coagulant, Fe$_2$(SO$_4$)$_3$, and a polymerized coagulant, Ferix-3, were used. Good coagulation was observed in broad pH range of 3 to 13, the floe size was increased with increasing pH of culture broth. The optimum pH of fermentation broth for cell recovery was 10 to 13. The optimum coagulant dosages to recover cells with 95% cell recovery were increased with increasing cell concentration. Optimal coagulant dosage was lower when the polymerized coagulant was used rather than the inorganic coagulant. The coexistence of NH$_4$$\^$+/ was increased coagulant requirement, and the coagulant requirement was 0.066g Fe$_3$$\^$+//g NH$_4$$\^$+/.

In this study, the dyeing conditions(temperature, time, concentration) are changed from various conditions on wool fabrics by using corydalis tuber extract in order to develop new natural dyes. The purpose of this study is to improve the dyeability, color fastness, and functionality and to derive optimal dyeing conditions by comparing and analyzing the changes of K/S values and surface color by dyeing pH changes, mordant method, and mordant type. As a result of the experiment, the optimum dyeing condition of the wool fabrics is shown dyeing temperature:$80^{\circ}C$, dyeing time:90min, dyeing concentration:100%. The dyeability by pH variants of corydalis tuber extract indicates that K/S values is higher alkaline than acidic. The mordant method of corydalis tuber extract showed pre-mordant has high K/S values. In terms of color fastness, marked improvement has not been shown despite of mordant treatment on wool fabrics. In particular, color change of color fastness to washing, color fastness to light indicates the low fastness. In addition, the functionality such as antibacterial activities and deodorization can be given at dyeing with corydalis tuber extract thus it is expected to be applied to underwear or apparel products for the elderly and infirm and children with weak skin that required high functionality.

This study investigated the functional properties of lateral roots of red ginseng following roasting treatment The ten different conditions, based on the central composite design for roasting parameters, were pre-established according to roasting temperature($140{\sim}240^{\circ}C$) and time($5{\sim}25\;min$). The functional characteristics were monitored using response surface methodology, whereby polynomial equations and correlation coefficients were investigated between roasting conditions. The functional properties of the samples were affected more by roasting time than temperature. The optimal roasting condition ranges for maximizing the functional qualities of lateral roots of red ginseng were predicted to be a roasting temperature of $194.5-210.9^{\circ}C$, and a roasting time of 13.8-20.0 min.

In this study, composite materials were prepared by varying the content of glass fiber and bamboo fiber in PP/glass fiber/bamboo fiber. Experiments were conducted to confirm the mechanical properties(tensile, impact and burst strength) and volatile organic compound content of the bamboo fiber composite prepared under these conditions. An improvement in the main properties was observed at a fiber content of 30wt%. When the fiber fraction was increased above 30wt%, the mechanical properties tended to decrease due to the agglomeration of fibers at higher load fractions. In addition, the content of volatile organic compounds increased as the content of bamboo fibers increased, which is thought to be due to the volatile organic compounds generated during the manufacturing process of the composite material being present in the composite material without escaping from the pores of the bamboo fibers and volatilizing at a certain temperature. As a result of confirming the physical properties of the composite, it is considered that the optimal mixing condition is 30wt% of bamboo fiber for the composite produced by varying the amount of bamboo fiber composite. In the future, it is thought that follow-up experiments to confirm and improve the pre-treatment conditions for reducing the content of volatile organic compounds in the manufactured composite material are possible.

In South Korea, most patients who visit trauma centers with abdominal injuries have blunt trauma, and penetrating injuries are relatively rare. In extremely rare cases, some patients are admitted with a long object penetrating their abdomen, and these injuries are referred to as abdominal impalement injuries. Most cases of impalement injuries lead to fatal bleeding, and patients often die at the scene of the accident. However, patients who survive until reaching the hospital can have a good prognosis with optimal treatment. A 68-year-old female patient was admitted to the trauma center with a 4-cm-thick tree branch impaling her abdomen. The patient was transported by a medical helicopter and had stable vital signs at admission. The branch sticking out of the abdomen was quite long; thus, we carefully cut the branch with an electric saw to perform computed tomography (CT). CT revealed no signs of major blood vessel injury, but intestinal perforation was observed. During laparotomy, the tree branch was removed after confirming that there were no vascular injuries, and enterostomy was performed because of extensive intestinal injury. After treating other injuries, the patient was discharged without any complications except colostomy. Abdominal impalement injuries are treated using various approaches depending on the injury mechanism and injured region. However, the most important consideration is that the impaled object should not be removed during transportation and resuscitation. Instead, it should only be removed after checking for injuries to blood vessels during laparotomy in an environment where injury control is possible.
