To 100 patients who underwent various operations under general anesthesia, Effortil and methoxamine were given in order to assess and to compare their effects on blood pressure and pulse rate. The drugs were administered intravenously in 6 to 10 mg doses when the systolic pressure fell to 80 mmHg. or lower during the operation. The results obtained are as follows: 1. Excellent pressor effect was obtained with Effortil in 84% of 50 patients while in 72% with methoxamine. 2. Both drugs were equally effectve in elevating both systolic and diastolic pressures. 3. The effect of Effortil on pulse rate was much less than that of methoxamine which moderately reduced the pulse rate, especially in the early phase. 4. No untoward effects of either Effortil or methoxamine were observed in this study.

BACKGROUND: Non-small cell lung cancer is one of the most frequent cause of death due to cancer in men, and its incidence among women is rapidly increasing. Although there has been a recent surge of interest in combined modality therapy for stage III non-small cell lung cancer(NSCLC), the optimal treatment is still not well established. Thoracic irradiation has long been the gold standard for locally advanced unresectable NSCLC. However, although conventional radiotherapy(XRT) can palliate symptom and improve local control of disease, it huts at most only a modest effect on survival. Recently, cisplatin(cia-diamminedichloroplatinum ) has been reported to enhance the cell-killing effect of radiation For patients with unresectable NSCLC, cisplatin-based concurrent chemoradiotherapy(CCRT) had the advantage of therapeutic response over XRT alone and therapeutic side effect more commonly occurred in CCRT group in EORTC(European Organization for Research and Treatment of Cancer) and other trials. Objectives : We compared therapeutic response, compliance, and side effects between CCRT and XRT in patients with advanced NSCLC. Patients and METHOD: Thirty patients with biopsy-proven inoperable NSCLC were randomized to one of two treatment arms. Arm A consisted of XRT, radiotherapy for 4~6 weeks(1.8 Gy given 20~33 times, in five fractions a week), and arm B consisted of CCRT, radiotherapy for 2 weeks(3 Gy given 10 times, in five fractions a week), followed by 3 week rest period and then radiotherapy 2 more weeks(2.5 Gy given 10 timed in five fractions a week), combined with 6mg cisplatin per square meter, given daily before radiotherapy. We evaluate therapeutic response, compliance, change of performance status, side effects, and radiation pneumonitis by using the author's made scoring system. RESULTS: There was no significant difference in therapeutic response and compliance. But there was a significantly lower laboratory complication and radiation pneumonitis in CCRT group (p<0.05). There's significant negative correlation between stage and therapeutic response score in both groups(R=0.353, p<0.05). In both groups, patients with squamous cell carcinoma had a tendency to higher therapeutic response score than those with adenocarcinoma. CONCLUSION: There was. no difference between CCRT and XRT in respect to therapeutic response and compliance. But CCRT had a advantage of decreased side effects.

Idiopathic bronchiolocentric interstitial pneumonia is one of idiopathic interstitial pneumonia, which has a relatively aggressive course and poor prognosis. It is characterized by diffuse centrilobular nodules radiologically with mainly bronchiolocentric inflammation and fibrosis associated with patchy alveolitis lacking interstitial granuloma histologically. This disorder is a recently classified disease category, and to our knowledge, there is no case report in Korea. We present a case of idiopathic bronchiolocentric interstitial pneumonia. A 62-year-old man presented with exertional dyspnea with a 1 month duration. The radiological findings showed extensive centrilobular lesions at both lungs. The surgical lung biopsy specimen demonstrated a centrilobular inflammatory process with small airway fibrosis and inflammation partially radiating into the interstitium. Therefore, the patient was diagnosed with idiopathic bronchiolocentric interstitial pneumonia. He was treated with immunosuppressants including steroids and azathioprine. However, his symptoms did not improve and he expired 7 months later due to an acute exacerbation of the interstitial pneumonia and probable infectious pneumonia.

Mucous gland adenoma of the bronchus is a rare benign tumor arising from the bronchial mucous gland. It accounts for less than 0.5 % of all lung tumors. In adults, tracheal tumors are most often malignant. Among benign tumors arising in the trachea, mucous gland adenoma of the trachea is extremely rare. First case was reported by Ferguson and Cleeland in 1988, as "Mucous gland adenoma of the trachea". Microscopic study shows it to arise from normal submucosal mucous glands forming glandular or tubular structures composed of mucous secreting cells. Common symptoms were cough, hemoptysis, recurrent and protracted pneumonia, shortness of breath, and wheeze. Duration of symptoms before diagnosis varied from a few weeks to 10 years with prolonged symptoms being usual. Management of these tumors should be complete excision, including pulmonary resection because two instances of recurrence after local excision have been reported.

PURPOSE: With recent anorectal physiologic studies, functional etiologies of pelvic outlet obstructive disease were evaluated in detail. The current study was designed to assess the clinical and the physiologic characteristics of patients with pelvic outlet obstructive disease. METHODS: one hundred two (102) patients with pelvic outlet obstructive disease were evaluated with anorectal physiologic studies, including the colonic transit time (n=66), anorectal manometry (n=88), defecography (n=102), anal sphincter EMG (n=50), and colonoscopy or barium enema (n=77). The patients were categorized as group I (nonrelaxing puborectalis syndrome), group II (rectocele), group III (sigmoidocele), and group IV (rectoanal intussusception). The clinical and the physiologic characteristics were compared between the groups. RESULTS: The mean age was 51.9 years, and the sex ratio was 1:1.9. the populations of the groups were group I 45.1% (n=46), group II 36.3% (n=37), group III 5.9% (n=6), and group IV 9.8% (n=10). In group II and group III, co-existing etiologies were more, and the incidences of female patients was higher (P<0.05). Delayed colonic transit time was noted in 11 patients (17%). Diverticula was observed in 6 patients (8%), polyps in 12 patients (16%), and melanosis coli in 14 patients (18%). On anorectal manometry, group I showed higher maximal voluntary contraction and mean squeezing pressure than the other groups (P<0.05). On defecography, group I had a shorter perineal descent at rest and a smaller anorectal angle at push (P<0.05). CONCLUSIONS: The current study showed the clinical and the physiologic characteristics of the each functional etiology in patients with pelvic outlet obstructive disease. These results provide fundamental data for diagnosis of and tailored therapy for pelvic outlet obstructive disease.

PURPOSE: The epidermal growth factor receptor (EGFR) is a one of the transmembrane receptor proteins that play an important role in initiating tumor cell signaling and growth and is regarded as a promising target for cancer therapy. The EGFR expression rate has been reported to vary according to the detection method. The aims of this study were to evaluate the EGFR expression rate of a colorectal carcinoma by using immunohistochemical staining (IHC) and semiquantitative reverse transcription-polymerase chain reaction (RT-PCR) and to analyze the correlation between these methods. METHODS: EGFR expression was investigated in tissue sections from 33 patients with a colorectal adenocarcinoma by using IHC and semiquantitative RT-PCR. IHC was performed with antibodies in a 1:40 dilution and a 1:80 dilution. The results of the three detection methods were compared with one another. RESULTS: The mean age of the patients was 61.9+/-12.2 years, and the male-to-female ratio was 1.2:1. The EGFR expression rates were 93.9% (31/33) in IHC with a 1:40 dilution, 87.9% (29/33) in IHC with a 1:80 dilution, and 66.7% (22/33) in RT-PCR. The result of IHC with a 1:40 dilution significantly correlated with the result of IHC with a 1:80 dilution (Pearson correlation 0.684, P<0.01). There was no correlation between semiquantitative RT-PCR and IHC (1:40 dilution, 1:80 dilution). CONCLUSIONS: The EGFR expression obtained by using IHC was consistent with different antibody dilutions. The expression rate obtained by using RT-PCR was significantly lower than that obtained by using IHC, and there was no statistical correlation between the expressions of EGFR obtained by using RT-PCR and IHC. A standardization for EGFR detection methods is needed to draw any conclusion concerning their activity in colorectal cancer.

PURPOSE: Biofeedback treatment is thought to be appropriate for patients with nonrelaxing puborectalis syndrome (NRPR). The aim of this study is to analyze the physiologic characteristics and to assess the outcomes of biofeedback treatment for patients with NRPR. METHODS: Forty-six (46) patients with NRPR were evaluated with anorectal physiologic studies, including colonic transit time (n=26), anorectal manometry (n=41), defecography (n=46), anal sphincter EMG (n=28), and colonoscopy or barium enema (n=33). The treatment consisted of a training program with EMG-based biofeedback for 30 minutes once a week and routine supportive care, including Kegel practice. RESULTS: The mean age was 52.8 years, and the sex ratio was 1 male to 0.6 female. A delayed colonic transit time was noted in 5 patients (19.26%). In the NRPR group, the maximal voluntary contraction and the mean squeezing pressure were higher than they were for other patients with pelvic outlet obstructive disease. Also, the perineal descents and the dynamic change of anorectal angle were shorter. Polyps were observed in 6 patients (18.2%), melanosis coli in 4 patients (12.1%), and diverticula in 3 patients (9.1%). The rectoanal inhibitory reflex (RAIR) was negative in 3 patients (7.3%). The patients underwent a mean of 4.0 sessions, and the mean follow-up was 7.4 months. Twenty-three (23) patients (82.1%) experienced improved of symptoms or EMG findings. The patients (17.9%) who did not improve had several abnormal findings: neuro-psychologic disease with delayed colonic transit time in 2 cases, negative RAIR in 2 cases, and melanosis coli in one case. CONCLUSIONS: We think that biofeedback training is an effective treatment for patients with NRPR. In addition, several factors, such as neuro-psychologic diseases, delayed colonic transit time, negative RAIR, or melanosis coli may influence the prognosis for biofeedback treatment, so further large-scaled studies will be needed to confirm these findings.

Psychrobacter sanguinis has been described as a Gram-negative, aerobic coccobacilli originally isolated from environments and seaweed samples. To date, 6 cases of P. sanguinis infection have been reported. A 53-year-old male was admitted with a generalized tonic seizure lasting for 1 minute with loss of consciousness and a mild fever of 37.8℃. A Gram stain revealed Gram-negative, small, and coccobacilli-shaped bacteria on blood culture. Automated microbiology analyzer identification using the BD BACTEC FX (BD Diagnostics, Germany) and VITEK2 (bioMérieux, France) systems indicated the presence of Methylobacterium spp., Aeromonas salmonicida, and the Moraxella group with low discrimination. The GenBank Basic Local Alignment Search Tool and an Ez-Taxon database search revealed that the 16S rRNA gene sequence of the isolate showed 99.30% and 99.88% homology to 859 base-pairs of the corresponding sequences of P. sanguinis, respectively (GenBank accession numbers JX501674.1 and HM212667.1). To the best of our knowledge, this is the first human case of P. sanguinis bacteremia in Korea. It is notable that we identified a case based on blood specimens that previously had been misidentified by a commercially automated identification analyzer. We utilized 16S rRNA gene sequencing as a secondary method for correctly identifying this microorganism.

Protein identification by peptide mass fingerprinting using matrix-assisted laser desorption ionization time of fight (MALDI-TOF) mass spectrometry (MS) can analyze unambiguously identity of the spots from a 2-dimensional electrophoresis (2-DE) gel. This study developed a technique for 2-DE of Salmonella enterica serovar Enteritidis (S. enteritidis) by improving the dissolution conditions by 2-DE using a pH 4 - 7 immobilized pH gradient (IPG) strip. This report examines the protein components from the patterns of the S. enteritidis protein. The most abundant protein displayed a great number of clusters within the pH 4.5 - 7 range with a molecular mass ranging from 35-80 kDa. Some of these spots were identified as metabolic related enzymes. The protein fraction was also analyzed using an immobilized pH gradient strip. Different proteins were identified on the spot according to the elongation factors. In addition, this study showed that the 2-DE analysis of S. enteritidis provides useful information regarding the S. enteritidis proteome, and this approach might provide a strategy for identifying bacterial proteins using a proteome technology.

Primary biliary cirrhosis (PBC)is a chronic inflammatory disease characterized by fibrous obliteration of intrahepatic bile ductules.Although the etiopathogenesis of PBC remains unclear,several studies suggest that a disordered immune response may be involved.This disease is commonly associated with various autoimmune diseases,such as Sjogren's syndrome,scleroderma, rheumatoid arthritis,Hashimoto's thyroiditis,polymyositis,and pernicious anemia.More than 80%of cases with PBC are accompanied by at least one autoimmune disorder,and 40%by two or more. Sjogren's syndrome,defined by dry eyes and xerostomia,may be found in 69 to 81%of PBC patients. However, concurrent coexistence of PBC and systemic lupus erythematosus (SLE)has been rarely described in the literature.We report a 46-year-old female with PBC and Sjogren's syndrome who also satisfied a classification criteria of SLE.
