Inflammation is the complex biological response of injured tissues to harmful stimuli. A cascade of biochemical events propagates and matures the inflammatory response, involving the local vascular system, the immune system, and various cells within the injured tissue. The immune system is often involved with inflammatory disorders, demonstrated in both allergic reactions and some myopathies, with many immune system disorders resulting in abnormal inflammation. An Arbitrary Waveform Generator (AWG) is a piece of electronic test equipment used to generate electrical waveforms for the treatment of patients. The patients with gastritis and arthritis have been known to have a relatively favorable prognosis with AWG treatment. Accordingly, we examined the effects of AWG treatment in gastritis and arthritis animal model. The compound 48/80 was used to induce animal gastritis model. The tissue malone dialdehyde (MDA) and serum histamine levels, and the activity of superoxide dismutase (SOD) in stomach tissue were measured. The tissue MDA and serum histamine levels in AWG treated groups exhibited the decreased tendency compared with control group, whereas the tissue SOD activity was slightly increased. The Freund's complete adjuvant was used to induce animal arthritis model as well. The paw edema volume and the width of ankle joint were determined. The AWG treatment significantly decreased the paw edema volume after 5th day of treatment. Although further studies should be performed to confirm the effects of AWG treatment, present study suggest that AWG treatment might be used as a complementary treatment for the gastritis or arthritis treatment.

Objective : We investigated the neuroprotective effect of anthocyanin, oxygen radical scavenger extracted from raspberries, after traumatic spinal cord injury (SCI) in rats. Methods : The animals were divided into two groups : the vehicle-treated group (control group, n=20) received an oral administration of normal saline via stomach intubation immediately after SCI, and the anthocyanin-treated group (AT group, n=20) received 400 mg/kg of cyanidin 3-O-${\beta}$-glucoside (C3G) in the same way. We compared the neurological functions, superoxide expressions and lesion volumes in two groups. Results : At 14 days after SCI, the AT group showed significant improvement of the BBB score by $16.7{\pm}3.4%$, platform hang by $40.0{\pm}9.1%$ and hind foot bar grab by $30.8{\pm}8.4%$ (p<0.05 in all outcomes). The degree of superoxide expression, represented by the ratio of red fluorescence intensity, was significantly lower in the AT group ($0.98{\pm}0.38$) than the control group ($1.34{\pm}0.24$) (p<0.05). The lesion volume in lesion periphery was $32.1{\pm}2.4\;{\mu}L$ in the control and $24.5{\pm}2.3\;{\mu}L$ in the AT group, respectively (p<0.05), and the motor neuron cell number of the anterior horn in lesion periphery was $8.3{\pm}5.1$ cells/HPF in the control and $13.4{\pm}6.3$ cells/HPF in the AT group, respectively (p<0.05). Conclusion : Anthocyanin seemed to reduce lesion volume and neuronal loss by its antioxidant effect and these resulted in improved functional recovery.

The purpose of this study is to analyze the physiological effects of non-elastic corset on women's health and pain through measuring the clothing pressure, subjective pressure sensation, blood velocity and metabolism. 5 women in their twenties were picked as our subjects, their average size being 85cm at bust girth, 69 cm at waist girth. With the subjects each wearing a corset, we are testing in artificial environment with a treadmill according to the planned exercise procedures. The average pressure of the corset is 0.938 kPa (maximum 3.006 kPa at 45 degree front bowing), which is 10.2 times higher than the control group, averaging from 9.3 times higher at resting, 11.4 times at walking, 11.1 times at running. The effect of corset pressure on the physiological responses of the body is increased more when exercise than when resting. Clothing pressure increased in the order of the postures: sitting > standing with 45 degree bowing > standing. They experienced a high level of tighten discomfort of 5.6 in the scale of 1.0 to 7.0 due to the high pressure of the corset when resting, after intense exercise the level increased to 6.0, while without corset the level increased 1.7 to 2.2. With corset on, the blood circulation did not increase even though when the body exercised and blood flow became unbalanced making great gaps between both at the right and left finger tips. Perspiration of chest and back decreased 37.3% when wearing corset; 27.5% at resting, 56.7% at walking, 25.8% at running, and 39.0% at recovery. With corset on oxygen consume and metabolism increased 9.0%, 7.9%, respectively, which means the corset makes the body uncomfortable. Lung volume exchange VE decreased almost 4.1~7.3% with corset on and $VCO_2/VO_2$, RER and total volume in lung, VT also decreased too, which means the digestion of stomach and lung function are inhibited due to the high corset pressure.

According to the original documents, Sagungsan is considered as an effective drug for controlling the hypertensive epistaxis induced by tension of autonomic nerve and it's hyperfunction. The present experiment was designed to understand the effect of Sagungsan extract on the hemostatic action, intracranial pressure, blood pressure and cardiovascular system in experimental animals. And thus the bleeding time, prothrombin time, capillary dilation, blood pressure, Intracranial pressure, and enzymatic analysis of the ATPase activities were studied. The result obtained here were as followings: 1. Sagungsan water extract reduced the bleeding time in mouse, and prolonged the prothrombin time in rabbits. 2. The drug extract increased the tail volume by capillary dilation in rats. 3. The drug extract inhibited the increase of intracranial pressure and arterial blood pressure in rabbits. 4. At the early time, the increase of arterial blood pressure by the drug extract significantly inhibited by pretreated atropin and regitine in rabbits. 5. The drug extract relaxed the smooth muscle by stimulating the Mg2+-Ca2+-ATPase activities of gastric sarcoplasmic reticulum isolated from rabbit stomach. 6. The drug extract stimulated the heart contraction by inhibiting the $Mg^{2+}-Ca^{2+}-ATPase$ activities of cardiac sarcoplasmic reticulum isolated from rabbit heart. The inhibitory mechanism was reversible and noncompatitive. 7. The drug extract increased the hepatic blood volume by stimulating the hepatic total ATPase activities and hepatic metabolism. 8. The drug extract acted as a tranquilizer by inhibiting the neural Na+-K+-ATPase activity. According to the results, Sagungsan water extract dilated the capillaries, stimulated the heart beat, and thus increased the blood flow with decreasing the intracranial pressure and blood pressure. These effects stanches the epistaxis collectively.

This study investigates the usefulness of body fix in 4DRT on Liver cancer trying to find tumor tissue's volume and located variations, absorbed dose on tumor and normal tissues. Test subjects 23 patients were agreed these test. These patient's have a 4 dimensional CT scan. We make an acquisition on patients CT image by two types -put on the body fix or not-. Average tumor volume reduced by 0.17% on GTV and 3.2% on CTV and PTV. Tumor's variation reduces 29.8%(anterior and posterior, AP) and 5.31% (upper and lower, UL). The absorbed tumor doses under put on the body fix was a little higher(1.3%) than other. Normal tissues'(normal liver, stomach, Rt. kidney, spinal cord) absorbed dose could be reduced approximately 5%. Therefore, using body fix on 4DRT for liver cancer patient is considered effectively.

Biodistribution studies has been carried out to elucidate the cause of poor bone imagings often encountered in using $methylenediphosphonate(MDP)-^{99m}Tc$ and to establish effective conditions in using the popular bone imaging agent. After 150 minutes from the I.V. injection of $MDP-^{99m}Tc$ to mice, the radioactivities accumulated at bone(B), liver(L), and stomach(S) were counted. The radiochemical purity (RCP), the volume, the radioactivity concentration and the amount of radioactivity of $MDP-^{99m}Tc$ were controlled. Data were expressed either in %cpm/g organ or % cpm/organ. The organ distribution ratios(B/L and B/S) were correlated with the RCP, the volume of injection, the radioactivity concentration etc. Results indicated that the RCP plays a major role in biodistributions. High radioactivity concentration and injection of a small amount is recommended. Negligible effect was observed with the amount of radioactivity. It has been confirmed that the up-to-date methods of RCP determinations cannot sensitively detect the sharply affecting trace impurities. A particular biodistribution pattern of crossed B/L and B/S lines was observed in case of using $MDP-^{99m}Tc$ of low RCP. In such a case, rather a higher dosage would be effective for improving the contrast between bone and liver.

"Uihakdokseogi(醫學讀書記)" is a casual work which mentions Ujaekyeong(尤在涇)'s thoughts on various problems found through extensive studying or in practice. The book does not focus on a single topic, thus the spectrum of the work is broad and is filled with problems which would interest most medical professionals. The major contents of the first volume of "Uihakdokseogi(醫學讀書記)" include differences of view on health preservation, the Five Circuit Phases[五運] and Six Atmospheric Influences[六氣], diseases, and the "Naegyeong(內經)", mentions on errors in transcription , and the gap between certain contents in "Yeongchu(靈樞)" and "Somun(素問)". U[尤在涇] asserts that Eum and Yang(陰陽) in a human should be in harmony as is the Gi(氣) of the sky and earth[天地] is, and that one should live according to the Gi(氣) of the four seasons to live a healthy life. He does not vary largely from the context of other writers on the matter of the Five Circuit Phases [五運] and Six Atmospheric Influences[六氣], and focuses on the concepts of predominant Gi[主氣], guest Gi[客氣], corresponding years[天符] , correlating years[歲會], and Taeeul corresponding years[太乙天符]. He mentions causes, symptoms, and treatments of various diseases such as cough due to asthenia of the viscera, stagnation of Yang(陽), stagnation of Eum(陰), abscess of the stomach, hard abscess of the intestines, upper emaciation, edema of the limbs, inability to raise the limbs, broken thigh, turbid fluid, inversion of Gi(氣) flow, sudden onset of fainting with cold extremities, diarrhea due to disorder of Gi(氣), and malaria. U[尤在涇] also points out faults of "Classic of Acupuncture and Moxibustion[甲乙經]" in the understanding of "Naegyeong(內經)".

Objective: This study investigated the measurement interval in the ultrasonographic gastric emptying test for patients with functional dyspepsia (FD) and the correlation between gastric emptying and the findings of various questionnaires. Methods: In total, 119 patients (59 patients with FD and 60 healthy controls) were recruited from July 2018 to June 2020. Gastric volume (GV) and gastric emptying half-time (T1/2) were measured by ultrasonography at fasting and again at 0, 5, 10, 15, 30, 45, 60, 90, and 120 min after meals (apple juice, 500 mL, 224 kcal), and the average half-time (average T1/2) was calculated. Questionnaires on food retention (FRQ), phlegm pattern e (PPQ), cold and heat (CHQ), deficiency and excess (DEQ), and spleen-qi deficiency (SQDQ), stomach qi deficiency pattern (SSDQ), visual analogue scale (VAS), and Nepean dyspepsia index-Korean version (NDI-K) were completed by all participants. The differences in GV and T1/2 were analyzed in participants whose maximal GV occurred at 0 min versus after 0 min. The correlation of the average T1/2 with the questionnaire scores was also analyzed after excluding erroneous data. Results: Patients with FD who took a certain amount of time to reach maximal GV after meals had a greater gastric volume up to about 30 minutes after meals, and the PPQ, DEQ, and NDI-K scores, especially for upper gastrointestinal symptoms and general weakness-related symptoms, showed statistically significant correlations with average T1/2. Conclusions: Ultrasonography can be a quantitative evaluation tool for FD. However, further studies on measurement methods based on FD physiopathology are required.

Purpose: With an increase in life expectancy, more elderly patients are presenting with gastric cancer. As a result it is yet be resolved whether laparoscopy assisted distal gastrectomy is a suitable treatment for elderly patients with early gastric cancer. This study retrospectively compared surgical outcomes of laparoscopy assisted distal gastrectomy between elderly and nonelderly patients with gastric cancer. Materials and Methods: The study group was comprised of 316 patients who underwent laparoscopy assisted distal gastrectomy between April 2005 and December 2010. Of these patients, 93 patients whose ages were 65 years or more were compared with 223 patients who were younger. Results: There were no differences in the short term outcome or minor complication rate between the elderly patients and the nonelderly patients. The hospital stay was significantly longer and the major complication rate was significantly higher for the elderly patients compared with nonelderly patients. Conclusions: Laparoscopy assisted distal gastrectomy for early gastric cancer in the elderly patients had comparable operation time and blood loss with the nonelderly group. However, the safety and advantage of laparoscopy assisted distal gastrectomy in the elderly patients need to be further studied in higher volume trials.
