One of the characteristics of the diagnostic method in Oriental medicine is a pulse diagnosis. In this technique, the examiner places his index, middle and ring fingers on the wrist of the patient's hand above the radial artery and determines the fullness or emptiness of the six Meridians on each hand. In order to make this subjective method more objective, three pressure transducer sensors were placed over the radial artery and its method was previously described.
In this study, we used this objective pulse diagnosis and selected the proper Meridian points according to 5 element theory and improper points without considering it. Then we investigated the changes of the pain threshold by the thermo-dolorimetric method before and after the acupuncture stimulation.
An allergic patient who developed athmatic attack by many drugs was going to have nasal polypectomy. Acupuncture points were selected by this pulse diagnosis. 9 healthy volunteers were examined whether five element or non-five element points would elevate pain threshold.
Results
(1) The elevation of pain threshold by thermo-dolorimetric method before and after the acupuncture stimulation were observed only when the proper Meridian points were stimulated.
(2) Nasal polypectomy was performed under acupuncture analgesia without pain following the selection of 5 element points by this objective pulse diagnosis.

BACKGROUND/AIMS: There is considerable variance in individual susceptibility to hepato-toxic effects of ethanol as evidenced by the finding that only about 10-20% of alcoholics develop alcoholic liver cirrhosis. The aims of this study were, 1) to get the data on the genetic polymorphisms of three major ethanol-metabolizing enzymes (ADH, CYP2E1, ALDH) in normal Korean adults, and to search for the specific genotypes influencing alcohol drinking behavior by the comparison of allele frequencies between healthy control group and heavy drinker group with or without liver disease, 2) to investigate the influence of the genetic polymorphisms of these enzymes on the susceptibility to alcoholic liver disease by the comparison of allele frequencies between heavy drinker group without liver disease and alcoholic liver cirrhosis group. METHODS: Healthy control group included 53 healthy males in military service without evidence of liver disease or alcoholism. Heavy drinker group without liver cirrhosis included 29 males who had been drinking 80g or more of alcohol daily for more than ten years but did not have any clinical evidence of liver disease. Alcoholic cirrhosis group included 43 male patients who had drunk 80g or more of alcohol daily for more than ten years and had clinical evidences of overt cirrhosis. Subjects with hepatitis B surface antigen or anti-hepatitis C antibody were excluded. Genotypes of the three enzymes were determined by PCR (polymerase chain reaction) and restriction fragment length polymorphism (RFLP) with genomic DNAs extracted from peripheral leukocytes. RESULTS: 1) In healthy Korean males, allele frequency of ADH22, ADH31, CYP2E1 c2 and ALDH22 was 81%, 94%, 30% and 14%, respectively. 2) The absence of ALDH22 or CYP2E1 c2 allele were significant risk factors for being a heavy drinker (odds ratio,' 0.09, 0.42, respectively). 3) Although it was not associated with the polymorphism of each ethanol-metabolizing enzymes, the susceptibility to alcoholic liver cirrhosis was significantly associated with combined genotypes of ADH2(22) & ADH3(1+1)& CYP2E1 B or C. COMCLUSION: Genetic polymorphisms of ethanol-metabolizing enzyrnes are significantly associated with the suseptability to alcoholic liver disease as well as alcohol drinking behavior.

The term malignant mesenchymoma has been applied to those tumors of the soft tissue of mesenchymal origin which are composed of tumor cells differentiating into two or more unrelated malignant forms in addition to the fibrosarcomatous element. Recently authors experienced a case of malignant mesenchymoma in the right axillary area. Microscopically the sarcoma revealed multiple pattern of differentiation, including liposarcoma, malignant schwannoma, fibrosarcoma, malignant fibrous histiocytoma and rhabdomyoblastoma. The presence of rhabdomyblastic cells were proved by immunochemical study utilizing desmin. This patient was treated with surgical excision and radiation.

OBJECTIVE: Previous studies indicate that emotion regulation problems in major depressive disorder (MDD) may be caused by difficulties in preferring useful emotions according to their goals. We investigated expected emotional usefulness and emotional preference in individuals with MDD (MDDs) and healthy controls (HCs). METHODS: Participants were given an interpersonal scenario with two different goals (confrontation and collaboration) and rated their willingness to participate in emotion-provoking activities and the expected usefulness of a particular emotion. RESULTS: MDDs were similar to HCs in expected emotional usefulness but showed different patterns of emotional preference. HCs preferred happiness to negative emotions across goals whereas MDDs did not show such pattern. In addition, HCs displayed goal-appropriate preferences whereas MDDs did not prefer certain emotions for specific goals. CONCLUSION: Although MDDs seemed to understand how useful an emotion can be, they did not show preference for goal-appropriate emotions. Interventions should address why MDDs have difficulty engaging in goal-appropriate emotions despite having full knowledge of the utility of emotions in achieving goals.

BACKGROUND: This study was aimed to investigate the perception on working conditions and utilization of clinical research coordinators (CRCs) among investigators and sponsors. METHODS: The participants of this cross-section study were 114 investigators and 138 sponsors including clinical research associates (CRAs) who have worked with CRCs. Data was collected with paper or electronic form of self-administered questionnaires and analyzed with descriptive statistics and chi2 test or t test. RESULTS: Among investigators and sponsors, 56.1 % and 95.0 % perceived regular full-time positions as proper type of CRC employment, respectively. Those who perceived monthly salary with incentive as proper payment system were 67.5 % of investigators and 68.8 % of sponsors. The proper salary for 2-year CRCs and 5-year CRCs were significantly higher in sponsors than investigators. Investigators perceived CRCs could handle 3 studies as the same time and 5 studies per year. In regard to the difficulty in utilizing CRCs, 68.4 % of investigators perceived lack of experienced CRCs and 84.8 % of sponsors did frequent turnover. Those who responded pooling CRCs by hospital or clinical trial centers as a good solution to hire CRCs easily were 81.6 % of investigators and 58.0 % of sponsors. CONCLUSION: Almost all investigators and sponsors perceived CRCs were helpful for improving the quality of clinical trials. We recommend each institution or clinical trial centers could introduce the central CRCs' employment and management with proper salary and workload based on the results to maintain experienced CRCs and lessen the turnover of CRCs.

PURPOSE: This study examined the effects of aerobic exercise using a flex band on the improvement of physical functions & body image in breast cancer women undergoing radiation therapy after a mastectomy. METHOD: Women with breast cancer(n = 26) were assigned to an experimental group(EG, n = 15) and control group(CG, n = 11). The E.G. participated in an aerobic exercise program with a 60% to 80% intensity of maximal heart rate for 25 minutes during the main exercise, 3 times per week, for 6 weeks. The EG did not exercise regularly for 3 months before participating in this program. The CG received no exercise treatment during the research period. Data were analyzed using the chi-square-test and Mann-Whitney U test by the SPSS version 11.0 program at a 5% significant level. RESULTS: Group analysis revealed that the EGwomen had significantly more improved cardiopulmonary functions, ROM of the affected shoulder joint, and body image compared to the CG. CONCLUSION: Aerobic exercise using a flex band may be an effective rehabilitative measure for mastectomy women with respect to cardio-pulmonary functions, ROM, & body image. Further studies are recommended to study early rehabilitation programs within 10 days post-operatively.

BACKGROUND: Osteopontin (OPN) is a glycoprotein and it participates in cell-cell and cell-matrix interactions. In vitro studies suggest that the OPN expression is associated with tumor metastasis, and especially with the metastasis of osteotropic tumors originating in breast, prostate and lungs. Since no human tissue study has suggested the means by which OPN participates in the tumorigenesis, angiogenesis, progression and metastasis of renal cell carcinoma (RCC), we evaluated the expression and prognostic significance of OPN in RCC. METHODS: Immunohistochemistry was performed with using the primary antibody for OPN on the archival paraffin-embedded tissue microarray specimens from 51 RCC patients who underwent radical or simple nephrectomy. RESULTS: In the normal kidney specimens, OPN was expressed in a few compressed distal tubules adjacent to the RCCs. In RCCs, the OPN expression was elevated in larger tumors (p<0.05) and in the tumor with low microvessel density (p<0.01). In the present study, univariate analysis indicated that stage, tumor size, lymph node and distant organ metastasis are significant prognostic factors for disease free survival (DFS) in RCC patients (p<0.01), but OPN is not (p=0.0661). Multivariate analysis indicated lymph node metastasis is the independent prognostic indicator of DFS (p<0.05). CONCLUSION: Though this study has statistical limitations, these results suggest OPN plays a role in tumor progression and metastasis and it may act as a potential prognostic indicator to predict the prognosis of RCC patients.

Steroid cell tumors of the ovary are extremely rare, accounting for only 0.1% of all ovarian tumors. Of these, steroid cell tumors, not otherwise specified (NOS) constitute about 56% of all steroid cell tumors. Most steroid cell tumors secrete steroid hormones, and only about 10% to 15% of patients are asymptomatic. The morphology of steroid cell tumors, NOS is predominantly reported to be solid, and a review of case reports from 1979 until now revealed only 5 cases that were mainly cystic tumors. The present case, in a patient who had undergone a previous hysterectomy and surgery for a peritoneal inclusion cyst, is reported due to its rarity and its unusual presentation, together with a brief review of the literature. The tumor showed no clinical signs and symptoms typical of a steroid hormone secreting tumor and had an atypical morphology, being primarily multi-septate cystic with a minor solid portion.

PURPOSE: To evaluate the usefulness of color Doppler ultrasonography in the differential diagnosis of breast masses. MATERIALS AND METHODS: We prospectively evaluated to pathologically proven breast lesions. Forty-three were benign (39 fibroadenomas, two papillomas and two lipoma) and 27 were malignant (25 infiltrating ductal cardinomas, one mucinous carinoma and one atypical medullary caricinoma). In 32 cases, we categorized color signal from 0 to III, according to the degree of vascularity, and analysed peak systolic velocity (PSV) and resistive index (RI). RESULTS: Color signals of malignant lesions tended to be high grade (II, III), whereas those of benign lesions tended to be low (0, I), and the difference was statistically significant (P<0.005). In the analysis of spectral waveform , correlation between RI, PSV and malignancy was statistically significant (P<0.02). RI above 0.7 and PSV above 10 were the highest recorded values for sensitivity and specificity. CONCLUSION: Color Doppler ultrasound is a useful modality to distinguish benign from malignant breast masses. Malignancy is suggested when the color signal is grade II or III, the resistive index is higher than 0.7, and peak systolic velocity is higher than 10cm/sec.

There is a direct relationship between the plasma concentration of the drugs and the magnitude of neuromuscular blockade in non-depolarizing neuromuscular blocking agents. But the classical pharmacokinetic data of succinylcholine have not been obtained because of the lack of an appropriate assay to detect plasma concentration hydrolyzed rapidly by pseudocholinesterase. The purposes of this study was to determine neuromuscular response from the release of minute interval of toumiquet occlusion after intravenous bolus adminstration of succinylcholine at one arm following blood flow occlusion at contralateral arm with pneumatic toumiquet. The twitch height of neuromuscular responses after adminisration of succinylcholine was completely depressed in the group(control) without occlusion, but 5.40+/-3.63% on 1 minute, 30.11+/-9.72% on 2 minutes, 85.00+/-4.19% on 4 minutes and 97.75+/-0.59% on 5 minutes after blood flow occlusion respectively. The onset time of maximum depression in each group was not significant different. At 5 minutes after succinylcholine given systemically, the twitch height was 8.35%, while it was 97.75% from tourniquet release on 5 minutes after blood flow occlusion. It is concluded that succinylcholine should be also related to plasma concentration in magnitude of neuromuscular block, and receptor binding(dissociation constant) more than plasma concentration in offset of neuromuscular blockade.
