레이저와 플라스마 광, 할로겐 광 중합기를 이용하여 각 개인의 우식 활성도를 측정할 수 있는지를 규명하기 위해 7-8세 아동 45명을 대상으로 치아의 순면과 협면에 각 광원을 조사하고 특수 필터를 사용하여 초기 치아우식증으로 판별된 치아의 개수를 측정하여 기존의 우식활성도 측정방법인 dDfFtT rate와 mutans streptococci 측정법 Lactobacilli 측정법과 비교, 평가하고 그 특이도, 민감도, 예측력을 평가하였다. 1. 아르곤 레이저, 플라스마 광, 할로겐 광 조사시 육안검사시 보다 유의하게 많은 초기우식 병소가 관찰되었다(p<0.05). 2. 아르곤 레이저, 플라스마 광, 할로겐 광을 이용한 우식활성도 측정법은 dDfFtT rate와 양의 상관관계(γ= 0.42, 0.41, 0.39)를 보였다(p<0.01). 3. 기존의 우식활성도 측정방법을 기준으로 하여 평가한 결과 특이도와 민감도, 예측력은 모두 레이저가 가장 높았으며 플라스마 광, 할로겐 광 순으로 나타났다. 이상의 결과를 종합하여 볼 때 아르곤 레이저와 플라스마 광, 할로겐 광을 이용한 형광법은 모두 양호한 진단학적 지표를 보여줌으로써 향후 광학적 우식활성검사법으로 활용 가능성이 높을 것으로 사료된다. The purpose of this study was to develop a practical caries activity test by fluorescence using laser, plasma light and halogen light. The subjects of study were 45 children of 7-8 years old. Argon laser, plasma light and halogen light were irradiated to buccal or labial surface of all teeth. Fluorescence of initial carious lesion from teeth was observed through barrier filter and the number of teeth showing lesion was counted. Visual examination for the dDfFtT, mutans streptococci screening test and Lactobacilli colony counting were also done. Data analysis was accomplished by Axelsson's method. The result from the present study can be summarized as follows. 1. Laser, plasma light and halogen light could detect the initial carious lesions better than visual examination(p<0.05). 2. There was positive correlation between laser(r=0.42), plasma light(r=0.41), halogen light(r=0.39) and dDfFtT rate(p<0.01). 3. The specificity, sensitivity and predictive value was showed highest value in laser. but was showed favorable value in plasma light and halogen light. In regard to above results, laser, plasma light and halogen light all considered to be reliable method for determining individual caries activity. And they were also considered to be practical method because it would be simple, inexpensive, and time saving method.

The purpose of this study was to examine EMG changes of the body according to method the holding during carrying object. The experiments were conducted with utilizing EMG analyses for five male and five female adults as subjects. The results were as followed. 1. The higher muscle action potential of vertical holding was shown than that of right holding when carrying objects in MMH work in proportion to the weight of the object. The came from the subjects using their brachial muscles much to maintain the angles of their wrist joints and elbow joints for keeping their stable postures while walking. 2. The higher muscle action potential of right holding was shown in right and left elector-muscles of their spines(L1-L2, L4-L5) while carrying in all stages of weights except 25kg objects than that of vertical holding. These results were caused from more use of brachial muscles than elector-muscles of spines in carrying weight objects. So vertical holding is more effective in carrying weight objects at a short distance than right holding.

Unilateral pulmonary artery hypoplasia (UPAH) is a rare disease in adults and is frequently accompanied by a congenital cardiac anomaly at a young age. The diagnosis is usually based on computed tomography (CT), angiography, and magnetic resonance imaging (MRI). However, no reports are available on retrograde flow in patients with UPAH. We describe a 68-year-old man with isolated UPAH and retrograde blood flow. He was admitted for dyspnea on exertion for the past 23 years. His diagnosis was delayed, as his symptoms and signs mimicked his underlying pulmonary diseases, such as emphysema and previous tuberculous pleurisy sequelae. A discrepancy was detected between the results of a ventilation-perfusion scan and the CT image. This was resolved by MRI, which showed retrograde blood flow from the right to the left pulmonary artery. Using MRI, we diagnosed this patient with isolated pulmonary artery hypoplasia and retrograde flow.

Background: Previous studies have suggested that the frequency of cancer is higher in patients with dialysis and kidney transplantation than in the general population. The study of cancer in patients treated with dialysis in Korea fewer reported. The aim of this study was to investigate the incidence, types of cancer, time to discovery of cancer and effect of early screening among patients on dialysis in Chosun University Hospital. Method: The study subjects were 25 cancer patients out of 796 end-stage renal disease (ESRD) patients maintained on hemodialysis or peritoneal dialysis at Chosun University Hospital from January 2002 to March 2010. We observed frequency of cancer, dialysis mode, cause of ESRD, time to discovery of cancer, cancer staging and cancer therapy among these patients. Result: Among the study population (796 ESRD patients), malignant disease were diagnosed in 25 patients(3.14%). Mean age at first dialysis was 54.3 yr. Mean age at cancer diagnosis was 59.4yr. Seventeen (68%) of our subjects were male and eight (32%) were female. The mean time from the start of dialysis to the diagnosis of cancer was 49.3(0-168) months. The most common cancer site was gastrointestinal tract (GIT) (32%) followed by urinary tract (20%) and genital tract (16%). During first year, cancer incidence highly compared to other period. Except for stage II, lower stage was longer time to interval cancer diagnosis. Conclusion: In ESRD patients, the incidence of GIT cancer and urinary tract cancer is higher, thus, careful surveillance for malignancies is recommended. Key word: End-Stage Renal Disease (ESRD), Cancer, dialysis.

Relaxation Patterns of Human Gastric Corporal Smooth Muscle by Cyclic Nucleotides Producing Agents

Kim, Young-Chul,Choi, Woong,Sung, Ro-Hyun,Kim, Heon,You, Ra-Young,Park, Seon-Mee,Youn, Sei-Jin,Kim, Mi-Jung,Song, Young-Jin,Xu, Wen-Xie,Lee, Sang-Jin,Yun, Hyo-Yung The Korean Society of Pharmacology 2009 The Korean Journal of Physiology & Pharmacology Vol.13 No.6

To elucidate the mechanism of cyclic nucleotides, such as adenosine 3',5'-cyclic monophosphate (cAMP) and guanosine 3',5'-cyclic monophosphate (cGMP), in the regulation of human gastric motility, we examined the effects of forskolin (FSK), isoproterenol (ISO) and sodium nitroprusside (SNP) on the spontaneous, high $K^+$ and acetylcholine (ACh)-induced contractions of corporal circular smooth muscle in human stomach. Gastric circular smooth muscle showed regular spontaneous contraction, and FSK, ISO and SNP inhibited its phasic contraction and basal tone in a concentration-dependent manner. High $K^+$ (50 mM) produced sustained tonic contraction, and ACh $(10\;{\mu}M)$ produced initial transient contraction followed by later sustained tonic contraction with superimposed phasic contractions. FSK, ISO and SNP inhibited high $K^+$-induced tonic contraction and also ACh-induced phasic and tonic contraction in a reversible manner. Nifedipine $(1\;{\mu}M)$, inhibitor of voltage-dependent L-type calcium current $(VDCC_L)$, almost abolished ACh-induced phasic contractions. These findings suggest that FSK, ISO and SNP, which are known cyclic nucleotide stimulators, inhibit smooth muscle contraction in human stomach partly via inhibition of $VDCC_L$.

Hepatitis C virus p7 induces mitochondrial depolarization of isolated liver mitochondria

You, Deok-Gyun,Lee, Hye-Ra,Kim, Won-Ki,Kim, Hyung Jung,Lee, Gi Young,Yoo, Young Do SPANDIDOS PUBLICATIONS 2017 MOLECULAR MEDICINE REPORTS Vol.16 No.6

<P>Hepatitis C virus (HCV)-encoded protein p7 is a viroporin that acts as an ion channel and is indispensable for HCV particle production. Although the main target of HCV p7 is the endoplasmic reticulum, it also targets mitochondria. HCV-infected cells show mitochondrial depolarization and ATP depletion; however, the function of HCV p7 in mitochondria is not fully understood. The present study demonstrated that treatment of isolated mouse liver mitochondria with the synthesized HCV p7 protein induced mitochondrial dysfunction. It also demonstrated that HCV p7 targeted isolated mouse liver mitochondria and induced mitochondrial depolarization. In addition, HCV p7 triggered matrix acidification and, ultimately, a decrease in ATP synthesis in isolated mitochondria. These findings indicate that targeting of mitochondria by HCV p7 in infected cells causes mitochondrial dysfunction to support HCV particle production. The present study provided evidence for the role of HCV p7 in mitochondria, and may lead to the development of novel strategies for HCV therapy.</P>
