  • Purpose: To analyze the newly developed vacuum assisted auto-lancing technique applied to the forearm for the purpose of obtaining an adequate blood sample for glucose test with minimal pain. Methods: Visual and facial pain measures were introduced to compare lancing pain between the forearm and fingertip in 58 normal females. Sampled blood volumes were accurately measured by computer scanning technique. Results: Visual pain measure demonstrated significant pain reduction effect of the forearm sampling compared with the traditional fingertip sampling, which was also consistent with facial pain measure results. Blood volume more than $0.5{\mu}L$, enough for blood glucose testing with modern glucometers, was collected in 399(86%) of 464 forearm samples. Conclusions: Capillary blood sampling could be performed with minimal pain on the forearm by the newly developed vacuum assisted auto-lancing technique. With some resampling when necessary, the forearm sampling seemed very useful, considering almost no pain felt by the patients.

  • 당뇨병 환자의 혈당검사시 통증을 최소화하는 새로운 진공 자동 채혈기법을 개발하였다. 특별히 고안, 제작된 채혈기구를 사용하여 전완부위에서 채혈침으로 피부를 관통한 직후 자동적으로 -100mmHg의 진공압력이 가해짐으로써 모세혈액이 흡입되는 자동화된 진공 채혈기법을 구현하였다. 진공 자동 채혈기법의 유용성을 검증하기 위하여 전완부위에서의 채혈용적을 측정하였다. 58명의 정상인을 대상으로 464회의 채혈을 시행한 결과 평균 채혈용적은 약 2.6$\muL$이었고 0.5$\muL$이상의 채혈빈도가 약 86%이었다. 최근 개발되고 있는 혈당계들은 0.3~0.5$\muL$의 모세혈액으로 혈당검사가 가능하므로 검사성공률 역시 약 86%로 추정되었다. 채혈통증 감소효과를 평가하기 위하여 손가락 및 전완부위 채혈 후 시각상사 통증척도를 사용하여 통증지수를 측정하였다. 전완부위 채혈시 통증은 손가락 채혈의 약 23%에 불과하였으며 거의 무통증 채혈이 가능하였다. 따라서 본 연구의 전완부위 진공 자동채혈기법은 전통적인 손가락 채혈에 비해 채혈통증이 25% 이하로 현저하게 감소하지만 검사실패율이 14%로써 경우에 따라 재채혈이 필요할 수 있다. 그러나 매일 수 차례 채혈해야 하는 만성 당뇨환자의 경우 검사기피를 방지할 수 있는 유용한 방법으로 생각된다.

  • Taurine is the most abundant free amino acid in the retina and transported into retina via taurine transporter (TauT) at the inner blood-retinal barrier (iBRB). In the present study, we investigated whether the taurine transport at the iBRB is regulated by oxidative stress or disease-like state in a conditionally immortalized rat retinal capillary endothelial cell line (TR-iBRB) used as an in vitro model of iBRB. First, [$^3H$]taurine uptake and efflux by TR-iBRB were regulated in the presence of extracellular $Ca^{2+}$. [$^3H$]Taurine uptake was inhibited and efflux was enhanced under $Ca^{2+}$ free condition in the cells. In addition, oxidative stress inducing agents such as tumor necrosis factor-$\alpha$ (TNF-$\alpha$), lipopolysaccharide (LPS), diethyl maleate (DEM) and glutamate increased [$^3H$]taurine uptake and decreased [$^3H$]taurine efflux in TR-iBRB cells. Whereas, 3-morpholinosydnonimine (SIN-1), which is known to NO donor decreased [$^3H$]taurine uptake. Lastly, TR-iBRB cells exposed to high glucose (25 mM) medium and the [$^3H$]taurine uptake was reduced about 20% at the condition. Also, [$^3H$]taurine uptake was decreased by cytochalasin B, which is known to glucose transport inhibitor. In conclusion, taurine transport in TR-iBRB cells is regulated diversely at extracellular $Ca^{2+}$, oxidative stress and hyperglycemic condition. It suggested that taurine would play a role as a retinal protector in diverse disease states.

  • 팔부위에서 혈당을 측정하는 것은 모세혈관에서 혈액을 채취하는 동안 느끼는 통증을 줄일 수 있다. 본 연구에서는 팔부위 혈당검사의 임상적 유효성을 평가하기 위해 팔부위 혈당검사결과를 손가락 및 정맥에서의 혈당검사결과와 각각 비교하였다. 당뇨환자 61명이 포함된 555명의 피검자를 대상으로 금식 상태에서 휴대형 혈당계로 손가락과 팔 안쪽 부위에서 혈당검사를 수행하였으며, 1시간 이내에 피검자 514명의 정맥혈액으로 혈당검사를 수행하였다. 측정값들에 대해 선형회귀분석, 급내 상관분석(intraclass correlation), Passing-Bablok 회귀분석 기법으로 다양하게 비교 분석해 보았다. 팔부위 혈당값은 환자군에서 손가락 및 정맥 혈당값과의 상관계수(r)가 0.97(P<0.0001)로 높은 선형관계를 나타내었으며, 정상군에서도 r값이 약간 작았지만 유사하였다. 채혈 부위에 따른 혈당값의 평균 차이는 두 집단에서 모두 ${\pm}10mg/dL$ 이내이었다. 급내 상관계수는 r값에 비교하여 약간 작았지만 두 집단이 유사한 수치를 나타내었다. Passing-Bablok 분석에서 기울기의 95% 신뢰구간과 절편은 각각 < ${\pm}20%$, < ${\pm}20mg/dL$로서 임상 허용범위 이내의 값을 나타내었다. 본 연구에서 사용한 세 가지 통계분석 결과 팔부위 혈당값이 손가락과 정맥에서 측정한 혈당값과 충분히 일치함이 입증되었다. 팔부위 혈당검사가 표준방법인 손가락 혈당검사와 높은 일치성을 나타내었으므로 금식 상태에서의 임상적용 가능성을 확인할 수 있었다.

  • We treated a 53 year-old male patient. He had alcoholic liver cirrhosis and diabetes. The main symptoms were fatigue, ascites, edema, anorexia, indigestion, constipation, and abdominal pain. We diagnosed him as 'the retention of pathogenic damp-heat in the liver and gall bladder’ and adminstered Saenggangeonbi-tang three times a day. We observed clinical symptoms, liver function test(AST, ALT, ${\gamma}-GT$, ALP, total bilirubin), nutritional state(total protein, albumin) and capillary blood glucose. After treatment, all the main symptoms disappeared and the patient's nutritional state has improved. Child's grade using the improvement index in liver cirrhosis has changed from B to A. Although the very mechanism of Saenggangeonbi-tang was not proven, we could suggest that Saenggangeonbi-tang is not toxic to the liver and has a good effect on alcoholic liver cirrhosis with diabetes mellitus.

  • Objectives : The purpose of this study was to analyze the trend of clinical research on quantitative indicators of Mibyeong in traditional chinese medicine(TCM). Method : The journal search was performed using china national knowledge infrastructure(CNKI) database. Our inclusion criteria were as following: TCM clinical researches for quantitative indicators of Mibyeong. Exclusion criteria were as following: non-TCM clinical researches, used intervention methods. Results : Eleven clinical researches were analyzed in this study. Four of these researches classify the Mibyeong as a type of pattern identification(PI) and studied the characteristics of the PI quantitative indicators. Mibyeong diagnosis was done through guidelines and questionnaires, each was used at a similar rate. Quantitative indicators mentioned in the selected researches were blood indices, nailfold capillary, complexion, color of tongue substance and coating, pulse wave diagrams and heart rate variability. Among them, seven researches related to blood indices were the most. Blood indicators include whole-blood viscosity, plasma viscosity, fibrinogen, packed cell volume(Hct), triglycerides, total cholesterol, HDL-C, LDL-C, glucose, BUN/CREA, luteinzing hormone, estradiol, follicle stimulating hormone, IgA, IgG, etc. Conclusions : Based on this results, in combination with western medicine, it seems necessary to try to interpret the Mibyeong in more various ways. Even if the same Mibyeong, it is necessary to identify the index which changes according to the PI or chief complaint, and to set the Mibyeong standard corresponding thereto.

  • This study was conducted to investigate the changes of exercise-induced stress response with acute anaerobic exercise in elite soccer players of university. The subjects were divided into elite soccer players of university (SG, n=10) and control group (CG, n=10). Subjects were tested three consecutive Wingate test for 30 seconds involving 2 times of 3 mins of resting time. In addition, whole blood and capillary blood were collected at rest, immediately post-exercise and 60 mins. of recovery time. Obtained results were as follows: Evaluated mean power and peak power of SG group was significantly higher than that of CG group in the all phase of Wingate test, respectively (p<.01). Although resting serum TG, TC, HDLC levels were not significant difference between SG and CG group, resting serum glucose of SG group was significantly lower than that of CG group. In addition, serum CRP levels of SG group were significantly lower than that of CG group at rest, immediately post-exercise and 60 mins of recovery time, respectively (p<.01). In serum cytokines, in spite of no significant differences in IL-1β levels between SG and CG group, IL-6 levels of SG group were significantly lower than that of CG group at immediately post-exercise and 60 mins. of recovery time, respectively (p<.05, p<.01). From these results, long-term combination training have a crucial role in amelioration of acute exerciseinduced stress response in elite soccer players.

  • Furosemide is a potent diuretic used in the horse for the prophylaxis of exercise-induced pulmonary hemorrhage(EIPH), and in a variety of clinical condition. The purpose of this study was to set up the effect of furosemide in Thoroughbred horses, and to examine the time of maximal effect of furosemide to prevent the EIPH. The animals of the experiment were 4 Thoroughbred racing horses(female, average 6 yrs, BW $507{\pm}80.2kg$) in Jeju stud farm and the experiment was cross-over design between furosemide(1 mg/kg IV) and normal saline(0.1 ml/kg, IV) administration. We investigated the changes of clinical signs(body weight, skin turgor, capillary refilling time, jugular distensibility), CBC(PCV RBC), serum chemistry(TP, AST, GGT, glucose, LDH, BUN and creatinine) and electrolytes ($Na^+,\;K^+,\;Cl^-,\;Ca^{2+}$) on 0, 30 mins, 1, 2, 4, 8 and 24 hrs in furosemide and saline administration roup, respectively. The weight decreased significantly(P<0.05) in 4 hrs after furosemide treatment, but skin turgor, CRT, jugular distensibility remained unchanged throughout the experimental period. RBC and PCV decreased after furosemide administration but soon recovered. TP increased to the highest level in 30 mins after furosemide administration and recovered in 8 hrs. Furosemide administration resulted in increases in glucose, AST, GGT, LDH, BUN, creatinine(P<0.05) and decreases in $Ca^{2+},\;Na^+,\;K^+,\;Cl^-$ (P<0.05). All of values were within normal range throughout the experimental period. There was the alteration of blood and serum chemistry after furosemide administration, all of values were within normal range. And the best time of furosemide administration will be 30 minutes before the racing in order to preventing EIPH.

  • Objectives : The purpose of this study is to investigate Acute and Subacute Toxicity, and Anti-cancer Effect of H Herbal-acupuncture on mice and rats. Methods : Balb/c mice were injected intraperitoneally with H Herbal-acupuncture for $LD_{50}$ and acute toxicity test. Sprague-Dawley rats were experimented in the same way for subacute toxicity test. H Herbal-acupuncture was injected into abdomen of mice having S-180 cancer cell line. Result : 1. During the test, $LD_{50}$ could not be counted since there was no expired subjects. 2. In an acute toxicity test, the loss of motility and reflex action was observed, but weight increased in the treatment group, compared with those in the normal group (P<0.05). 3. In an acute toxicity test of serum biochemical values of mice, glucose increased in the treatment group II while total cholesterol was increased in the all treatment groups (P<0.05). 4. In a subacute toxicity test, a little loss of motility and reflex action was observed in the treatment group. Weight of mice in the treatment group decreased on the 28th day. 5. In a subacute toxicity test, liver weight was decreased but lung weight of mice increased in the all treatment groups (P<0.05). 6. As a result of measuring Complete Blood Count test (CBC) of rat, HCT was decreased in treatments even though it was not significant, compared with the normal group (P<0.05). 7. In a serum biochemical value test of subacute toxicity, total protein and albumin decreased in the all treatment groups. Creatinine, glucose, GOT increased in the treatment group I compared with the control group. Alkaline phos-phatase decreased in treatment II group, compared with the control group (P<0.05). 8. Median survival time that was measured in the rats treated with sarcoma-180 cancer cell Median decreased in the treatment group, compared with the control group (P<0.05). 9. Natural killer cell activity showed significant reduction at 100:1 and 10:1 E/T ratio while it increased at 50:1 E/T ratio. It is inferred that there was an error in the experiment (P<0.05). 10. In an interleukin-2 productivity test, even though it decreased in lung cancer, and increased in abdomen cancer, but it was only a small difference (P<0.005). 11. After injecting B16F10 cell into a capillary vessel of C57BL/6 mice and generating metastasized lung cancer, the lung was examined with the naked eye. It was not possible to see metastasized cancer in the all groups on the seventh day but the cancer was viewed on the fourteenth day. The number and volume of metastasized cancer in the treatment group enlarged in the treatment group, compared with the control group. Conclusion : According to the results, H herbal-acupuncture took no effects in cancer.

  • Garlic occupies a special position among the many foods of vegetable origin because it is the sole food for Koreans during the their lives. And vitamin A has been ingested by forms of food or additives. Cadmium has been described as one of the most dangerous trace elements in the food and environment of man and livestocks. Since the de novo synthesis of stress proteins can be detected early after exposure to some agents, analysis of cadmium-induced changes in gene expression , ie. alterations in patterns of protein synthesis, may be useful to develop as biomarkers of exposure and damage for food hygiene. He acute and chronic combine effects of cadmium (Cd, CdCl2 20mg/kg), garlic oil(Dds: diallyl disulfide 50mg/kg, 3 times a week) and vitamin A(Ra: retinol acetate 50,000 IU/kg, 3 times a week) on Wistar male rats were evaluated concerning cadmium contents, tissues enzyme activity, HSP expression histopathological and electron microscopical examinations. The results of the study are as follows ; 1. Less cadmium was absorbed through the digestive tracts, but the ratio of contents in tissue were not changed by the simultaneous adminstration of diallyl disufide or retinol acetate. 2. ALT(alanine aminotransferase) , AST(aspartate aminotransferase), glucose, BUN (blood urea nitrogen), creatinine, the key indices of the clinical changes in hepatic and renal function were significantly hanged by the cadmium treatment after 1 week in liver, after 4 weeks in kidney. 3. Histopathological changes in cadmium treated rats were appeared at 8 weeks age treatment in kidneys. Homogenous eosinophilic material was accumulated in cortical and collecting tubular lumens at 16 weeks. Degenerated or necrotized tubular cells were observed in cortex and medulla. Degenerated seminiferous tubules and homogeneous eosinophilic material was seen in interstitial tissue of rat treated with cadmium for 16 weeks. Calcium deposits were seen in degenerated seminiferous tubules and the tubules showed severe calcification of rat treated with cadmium for 16 weeks. Electron microscope changes in kidney were observed in rats treated with CdCl2 20 mg/kg. Proximal convoluted tubule cells showed selling of cytoplasm and narrow lumen. Capillary endothelial cells showed cytoplasmic vacuoles and swelling. Degenerated epithelial cells were accumulated in tubular lumen of kidney. 4. Enhanced synthesis of 70 KDa relateve molecular mass proteins were detected in 2 hours after cadmium, exposure, with maximum activity occurring at 8~48 hours. Induction of HSP 70 was evident at proximal tubules and glomeruli in kidney. Testicular cells produced enough HSP to be detected normally. From the above results, it could be concluded that HSP70 induction by the cadmium treatment was a rapid reaction to indicated the exposure of xenobiotics, and retinol acetate reduced the cadmium induced nephrotoxicity.
