3.The Composition of Modified BHI Medium for Optimal Growth of Malassezia spp..
Korean Journal of Medical Mycology 2015;20(1):1-5
BACKGROUND: There are several media for culture of Malassezia spp., such as Leeming & Notman (LN) medium, modified Leeming & Notman (mLN) medium, Dixon's medium and modified Dixon's medium etc. It is known that Malassezia spp. grow well in these media in general, but the kind and amounts of their ingredients are various and un-uniform according to researchers. Author propose the new and transparent BHI based medium for the optimal growth of Malassezia spp. OBJECTIVES: The purpose of this study was to design the simple and transparent BHI based medium and find essential ingredients for the growth of M. globosa and M. obtusa. METHODS: The colony size of eight standard strains (M. dermatis, M. furfur, M. globosa, M. japonica, M. obtusa, M. sloofiae, M. sympodialis, M. yamatoensis) on the modified BHI (mBHI) agar media with different ingredients was observed by naked eye after seven day culture. The compositions of mBHI medium were as follows; mBHI-1 was supplemented with 0.7% dextrose, 1.5% Tween 80, 1% glycerol to BHI medium, mBHI-2 was supplemented with 1.5% Tween 40 to mBHI-1 instead of Tween 80, mBHI-3 was supplemented with 1.5% Tween 60 to mBHI-1 instead of Tween 80, mBHI-4 was added with 0.8% bile salts to mBHI-1. mBHI-5 was supplemented with 1.5% Tween 60 to mBHI-4 instead of Tween 80, and mBHI-6 was supplemented with 1.5% Tween 40 to mBHI-4 instead of Tween 80. pH of six mBHI media was all adjusted to 6.5. RESULTS: M. furfur & M. japonica were grown well on mBHI-1 agar, but M. globosa & M. obtusa were not grown and others grown poorly. M. globosa & M. obtusa were not grown on mBHI-1 & mBHI-4 containing Tween 80 as lipid source, but others grown on all mBHI media. The media that all eight Malassezia strains grew well were slightly turbid mBHI-5 & transparent mBHI-6 medium. CONCLUSIONS: M. globosa & M. obtusa need glycerol and bile salts as well as Tween 60 or 40 instead of Tween 80 for growth. M. furfur & M. japonica need not bile salts for growth. Author proposes the transparent modified BHI medium supplemented with 0.7% dextrose, 1.5% Tween 40, 1% glycerol and 0.8% bile salts (mBHI-6) as new standard medium for culture of eight Malassezia species.

4.The Growth Inhibition Effect on the Causative Bacteria of Bacterial Vaginosis by Bacterial Strains Isolated from the Vagina of a Healthy Woman.
Journal of Bacteriology and Virology 2014;44(3):244-251
Two Gram-positive rod strains isolated from the healthy vagina of a woman were tested for the possibility as probiotics. One strain was identified as Steroidobacter denitrificans (YH1) and the other as Lactobacillus crispatus (YH2) by 16S rRNA partial sequencing. The Casman agar and Man-Rogosa-Sharpe (MRS) agar were mixed in same quantity, supplemented with 5% human rbc lysate (CMB agar). The Wilkins-Chalgren agar and MRS agar were mixed in same quantity (WCM agar). Gardnerella vaginalis was cultured in Casman broth, supplemented with 5% human rbc lysate and 1,000 x-diluted with normal saline. Bacteroides fragilis, Mobiluncus mulieris and Peptostreptococcus asaccharolyticus were cultured in Wilkins-Chalgren anaerobe broth and 2,000x-diluted. S. denitrificans YH1 and L. crispatus YH2 were cultured in MRS broth anaerobically and 100x-diluted. The diluted suspensions of B. fragilis, M. mulieris and P. asaccharolyticus were inoculated on WCM agar and G. vaginalis on CMB agar by cotton swabs. Ten microl aliquots of YH1 and YH2 were inoculated on the center of WCM agar and CMB agar. The growth inhibition zone diameters of B. fragilis, G. vaginalis, M. mulieris and P. asaccharolyticus by YH1 were 35 mm, 35 mm, 25 mm and 60 mm. The inhibition diameters by YH2 were 25 mm, 30 mm, 20 mm and 40 mm, respectively. These results implicate that S. denitrificans YH1 can be the stronger probiotics for the treatment of bacterial vaginosis than L. crispatus, compared inhibition zone diameters by YH1 and YH2.

5.The Growth Inhibition Effect on the Bacterial Vaginosis Causative Bacteria by Citric Acid and Trisodium Phosphate.
Journal of Bacteriology and Virology 2015;45(3):228-234
Bacterial vaginosis (BV) is the most frequent vaginal disease being apt to relapse. The growth inhibition effect of the mixture of citric acid (CA) and trisodium phosphate (TSP) on BV causative bacteria and probiotics was measured. Gardnerella vaginalis was reduced to zero in WCCT-1 (CA 0.25% and TSP 0.55% in Wilkins-Chalgren broth), 2.0 x 10(4)/ml in WCCT-2 (CA 0.5% and TSP 0.8% in WC), and 3.3 x 10(3)/ml in WCCT-3 (CA 1.0% and TSP 2.6% in WC) comparing with 1.3 x 10(5)/ml in WC after 48 h. Bacteroides fragilis was reduced to 6.0 x 10(3)/ml in WCCA (CA 0.34% in WC), 2.3 x 10(2)/ml in WCCT (CA 0.5% and TSP 0.2% in WC), 7.0 x 10(3)/ml in WCHCl (HCl in WC) after 48 h. Mobiluncus mulieris was reduced to 1.08 x 10(4)/ml in WCCA, 1.03 x 10(3)/ml in WCCT, and 10 ea/ml in WCHCl after 48 h. Peptostreptococcus asaccharolyticus was completely inhibited in WCCA, WCCT, and WCHCl after 24 h. Probiotics, Steroidobacter denitrificans YH1 (3.4 x 10(7)/ml) and Lactobacillus crispatus YH2 (2.7 x 10(6)/ml), grew to 1.25 x 10(8)/ml and 2.6 x 10(7)/ml in MRSCA (CA 1.0% in MRS), 1.8 x 10(7)/ml and 4.6 x 10(6)/ml in MRSCT (CA 1.5% and TSP 0.58% in MRS), 1.2 x 10(8)/ml and 2.3 x 10(7)/ml in MRSHCl after 48 h, respectively. These results mean that the CA-TSP mixture can be used as the useful vaginal pH controller, growth inhibitor on BV causative bacteria, and an efficient means for settlement of probiotics.

"Dual LAD" was defined as the early bifurcation of the proximal LAD into two vessels : a short LAD which remained in the anterior interventricular sulcus and does not reach the apex, and a long LAD which leaves the anterior interventricular sulcus only to return to the distal sulcus and continue to the apex. Recognition of "Dual LAD" is essential to prevent errors of interpretation of the coronary arteriogram and for planning of optimal surgical therapy. We report 2 cases of "Dual LAD" with the review of the literatures.

Among 104 patients who visited a local clinic with increased, bad-smelling vaginal discharge, twenty-nine women (27.9%) were found to have bacterial vaginosis (BV) according to the Amsel's composite clinical criteria (homogeneous thin gray discharge, positive amine test, vaginal pH over 4.5, positivity of clue cell by Gram stain). The specificity, sensitivity and positive and negative predictive values of the Amsel's composite clinical criteria were estimated in relation to the G. vaginalis isolation rate. Fifty-two strains of G. vaginalis (50%) were isolated from vaginal swabs taken from 104 patients. The sensitivities of clue cells and G. vaginalis isolation were both 96.6% (28) in the 29 BV patients. The specificities of clue cells and the presence of G. vaginalis were 85.3% and 68.0%, respectively. But the sensitivity, specificity, and positive and negative predictive values of the combination of clue cells and morphotype of G. vaginalis were 93.1%, 92.0%, 81.8% and 97.2%, respectively. The sensitivity, specificity and positive and negative predictive values of amine test were 89.7%, 98.7%, 96.2% and 94.9% in the 29 BV patients. Among 52 strains of G. vaginalis, 34 strains (87.2%) were isolated from the 39 clue cell positive samples and the remaining 18 (27.7%) from the 65 clue cell negative cases. Twenty-four strains (92.3%) were isolated from 26 amine test positive samples and the remaining 28 (35.9%) from 78 amine test negative cases. According to these results, it seems that the amine test is a useful test for the diagnosis of BV. However, we propose the combination criteria of clue cells and G. vaginalis morphotype in vaginal discharge should give more objective results than the amine test for the diagnosis of BV. The sensitivity and specificity of vaginal pH over 4.5 were 86.2% and 57.3%, and those of homogeneous discharge 93.1% and 65.3%, respectively. These two criteria were not as specific as clue cells and amine test for the diagnosis of BV. These results suggest that BV could be diagnosed more simply and precisely with the finding of clue cells spotted with Gram variable polymorphic bacteria by means of Gram stain of vaginal wall swabs.

We studied 70 cases of transmural myocardial infarction with first attack to look into the coronary anatomy of the infarct-related artery in the time course of infarction and evaluate the left ventricular wall motion according to patency of the infarct-related artery. The following result were obtained. 1) Among 70 cases with transmural myocardial infarction, 47(67.1%) had anterior infarction and 23 (32.9%) inferior infarction. Mean age of the total cases was 52.1+/-10.6 and M:F ratio was 7.8:1. 2) 28 cases were single vessel disease(40.0%), 19 cases were two vessel disease(27.1%), 18 cases werew three vessel disease(25.8%) and 5 cases had insignificant coronary stenosis (7.3%) with 4 cases of normal coronary artery. 3) The total occlusion rate of the infarct-related artery in 70 cases was 48.6%. The total occlusion rate of the 8 cases catheterized within 1 day was 87.5%, that of the 17 cases from 2nd to 15th day 52.9% that of the 23 cases from 16th day to 2nd month 39.1%, that of the 15 cases from 3rd to 12th month 40.0% and that 7 cases from 2nd and 6th year 42.8%. These results suggest that the natural resolution of the infarct-related artery has almost happened within 2 weeks. 4) The left ventricular ejection fraction was higher and the left ventricular end-diastolic pressure was lower in the group with incomplete occulsion of infarct-related artery than in those with complete occulsion, and left ventricular wall motion was better in the group with incomplete occulsion of the infarct-related artery than in those with complete occulsion.
