The antimicrobial agents reduced infectious diseases significantly. However, antibiotic resistance has followed for almost every antimicrobial agent. Especially, Staphylococcus aureus was one of the most notorious for the multidrug resistance. Streptomyces sp. 681 has been selected for antibiotic-producing strain against methicillin-resistant Staphylococcus aureus (MRSA) from 1,000 strains of Actinomycetales which had been isolated from soil. In antimicrobial susceptibility test, all of the test strains were susceptible to vancomycin. However, most strains of Staphylococcus aureus were found to be resistant to methicillin. Ninety eight (75%) strains out of 129 strains showed multiple resistance pattern to more than 5 antimicrobial agents. The MIC values of the purified antibiotic (K-681) were 1-32 ug/ml against Gram-positive bacteria compared to >128 ug/ml against Grarn-negative bacteria or fungi. The MIC was 8 ug/ml for 90% of the 129 clinical isolates of S. aureus. The antibiotic showed no cytotoxicity against P 388, HeLa, and S180 at the concentration of 500 ug/ml.

Meigs' syndrome is a benign ovarian tumor associated with ascites and pleural effusion. Elevated cancer antigen 125 (CA-125) in Meigs' syndrome is an unusual clinical condition reported in few cases. We report here on a 61-year-old woman who presented with dyspnea; in imaging assessment, a heterogeneous pelvic mass measuring 12 x 11 cm with ascitic fluid was reported. Pleural effusion was detected on Chest X-ray. Aspiration of pleural fluid showed no evidence of malignancy. CA-125 level was 347 IU/mL. The patient underwent laparotomy during which a mass measuring 12 x 11 cm was detected in her left adnexa. Histology showed ovarian thecoma. The mass was resected, and, after that, the symptoms disappeared and CA-125 level reached 19 IU/mL. The patient had experienced no problem after 12 months of follow up. Although postmenopausal women with ovarian tumor, ascites, pleural effusion, and elevation of CA-125 levels probably have malignant ovarian tumors, Meigs' syndrome must be considered in the differential diagnosis.

Epithelioid trophoblastic tumor (ETT) is a rare gestational trophoblastic neoplasm composed of intermediate trophoblasts. Most cases of ETT are reported in women of reproductive age following a prior gestation within 2 weeks to 30 years. ETT is extremely rare in postmenopausal women. It is commonly misdiagnosed as a poorly differentiated carcinoma or another type of gestational trophoblastic tumor. We report a case of ETT in a 56-year-old woman that developed 23 years after the patient's last pregnancy.

Purpose: Gastric subepithelial tumor (GST) is a disease entity that includes all gastric subepithelial lesions. The oncologically safe surgical technique is complete resection with adequate resection margins. Most of the studies about laparoscopic gastric wedge rsection (LGWR) in GST focus on oncologic curability or surgical effectiveness. However, studies on the factors associated with the operation time are rare. Therefore, this study was conducted to analyze and compare the factors associated with the operation time of LGWR. Methods: From 2010 to 2019, 145 consecutive patients undergoing LGWR were reviewed retrospectively. Clinical characteristics of GST and operation time were analyzed and compared. Results: A total of 145 patients was enrolled and reviewed. There were 59 males (40.7%) and 86 females (59.3%) with a mean age of 53.6 years and mean body mass index (BMI) of 23.9 kg/m 2 . Mean tumor size was 2.9 cm and mean operation time was 66.0 minutes. In statistically, the mean operation time showed significant association with tumor size, BMI, longitudinal tumor location and tumor location between lesser and greater curvature. In multivariate analysis, tumor size, BMI and longitudinal classification of tumor location are statistically significant. Conclusion A shorter operation time is expected when there is a small tumor, low BMI and mid portion of the stomach GST. Preoperative evaluation for tumor size and body weight is important. In patients with large GST, obesity and both end stomach GST, we think that pre-operative preparation for long operation time should be considered.

OBJECTIVES: The purpose of this study is to determine methods of dental caries prevention by investigating the use of compounds of Diospyros kaki (D. kaki) peel, Momordica charantia (M. charantia), and Canavalia gladiata (C. gladiata) extracts to limit the cariogenic traits of Streptococcus mutans (S. mutans), such as their ability to proliferate and adhere to the tooth surface. METHODS: Broth microdilution and the agar spreading assay were used to determine the antimicrobial effect and minimum inhibitory concentration (MIC) of S. mutans extracts. In order to identify the adhesive ability of S. mutans at varying concentrations, culture plates were first stained with 1 ml of 0.01% crystal violet for 15 minutes at room temperature, and then eluted with 1 ml of EtOH:Acetone (8:2) solution for 15 minutes in a 37℃ incubator. Eluted solutions were then evaluated by use of a spectrophotometer at 575 nm. RESULTS: Experiments were conducted in order to investigate the effectiveness of D. kaki peel, M. charantia, and C. gladiata extracts on limiting the proliferation of S. mutans. The MIC was measured as an indication of whether the antibacterial activity of D. kaki peel, M. charantia, and C. gladiata extracts had a significant bacteriostatic effect on S. mutans. M. charantia extract was effective for growth inhibition on S. mutans at a minimum concentration of 0.25%. From the adhesion ability assay, M. charantia extract had an anti-adhesive effect. CONCLUSIONS: These results indicate that M. charantia extract demonstrates antibacterial activity and has an anti-adhesive effect on S. mutans. Due to these properties, M. charantia extract may be used to prevent dental caries.

To validate ventricular diastolic phase parameters of reconstructed transmitral flow rate curve by M-mode, 2-dimensional and pulsed Doppler Echocardiography, these parameters were compared with same parameters by left ventriculography. The study population was 22 patients who received both coronary arteriography and echocardiographic examination. Transmitral flow rate curve and left ventricular filling volume curve were reconstructed from transmitral flow velocity curve by pulsed Doppler, mitral annulus diameter by two diameter by two dimensional and diastolic motion of both mitral leafltes by M-mode echocardiography. From left ventriculography, left ventricular filling volume curve and transmitral flow rate curve were made using area-length method by Sandler and Dodge. From trasmitral flow fraction, 1/2 diastolic time filling fraction, normalized peak filling volume, 1/3 diastolic time filling fraction, 1/2 diastolic time fraction, normalized peak early filling rate and ratio of early to late peak filling rate were measured. Correlation between same parameters derived from echocardiography and left ventriculography were observed. 1) Total diastolic filling volume:correlation coefficient r=0.47, P<0.05. 2) 1/3 diastolic time filling fraction:correlation coefficient r=0.90, P<0.001. 3) 1/2 diastolic time filling fraction:correlation coefficient r=0.80, P<0.001. 4) Normalized peak early filling rate:correlation coefficient r=0.57, P<0.01. 5) Ratio of early to late peak filling rate:correlation coefficient r=0.85, P<0.001. Therefore, left ventricular diastolic phase parameters of reconstructed transmitral flow rate curve using, M-mode, 2-dimensional and pulsed Doppler echocardiography seems to be useful for the noninvasive evaluation of the left ventricular diastolic function.

A case of gallbladder perforation without cholecystitis or trauma is described herein. The patient was a 74-year-old woman who initially presented with right lower quadrant pain of the abdomen. A laparotomy was performed with the impression of an acute appendicitis at a local clinic. However, the appendix was normal and a large amount of bile was noted in the peritoneal cavity. The patient was referred to our hospital. An exploratory laparotomy was performed with the suspicion of a hollow viscous perforation. A pin point perforation of the gallbladder fundus was identified. There were no gallstones or definite inflammation of the gallbladder wall. Although gallbladder perforation without cholecystitis or trauma is rare, gallbladder perforation without cholecystitis should be considered in elderly patients with bile peritonitis of unknown etiology.
