For the overproduction of glutathione, Candida sp. mutant was isolated by the treatment with U.V. light. The highest glutathione production of Candida sp. mutant was obtained after shaking culture for 48 hours in the cullture medium containing glucose 1.5%(w/v), yeast extract 4.0% (w/v), KH2PO4 0.04%(w/v), biotin 5 ng/ml, and L-cysteine 0.04%(w/v). The optimal pH and temperature for the glutathione production were pH 6.0 and 25C, respectively.

Candida osteomyelitis affecting maxillofacial bones has been scantly documented in the literature. Infantile osteomyelitis is an uncommon and life-threatening disease. Candida osteomyelitis causes significant morbidity. The present report describes a case of a 9-month-old infant with infantile osteomyelitis secondary to candida infection. This report describes its presentation and the management of palatal fistula in an infant.

This study investigated whether a correlation exists between proteinase activity, phospholipase activity and adherence of Candida albicans to buccal epithelial cells by using of various strains isolated from oral cavity. The proteinase activity of 30 strains was tested by culture on agar media that contained bovine serum albumin as a nitrogen source. Using the serum-protein-agar method to test proterolysis of serum albumin in 20 strains of Candida albicans. Twenty-six strains of Candida albicans were phospholipase producers and the degree of phopholipase activity of experimental strains were $0.51{\sim}0.89$ measured by Pz-value. Twenty-eight strains of Candida albicans were adhersive to buccal epithelial cells and 15 strains were foung significantly active adherence. Fifteen strains of Candida albicans were correlated with proteinase activity and adherence to epithelial cells and concomitantly 20 strains of Candida albicans were also correlated with phospholipase activity and adherence. In conclusion our investigation provides evidence of a correlation between quantitative proteinase, phospholipase and adherence. An association of these parameters may be an important contributory factor for pathogenicity.

Purpose: The purpose of this study is to compare the adhesion of Candida albicans according to build angle in 3D printing denture base resin. Methods: The 3D printing was performed by setting the build angle of the disk type specimen designed by CAD program at 0 degree, 30 degrees, 60 degrees, and 90 degrees. Surface roughness was measured using a non-contact 3D microsurface profiler. The specimens were incubated in Candida albicans suspension for 24 hours. The attached Candida albicans were detached by cell scraper. The suspension of detached C. albicans was serially diluted and plated on Trypticase soy broth. After 48 hours of incubation, total colony forming unit was counted. Results: There was no significant difference in surface roughness(Sa) between the test groups, but the interlayer boundary was observed. There was no statistically significant difference in total colony forming units of Candida albicans between the test groups. Conclusion: There was no difference in the average surface roughness and adhesion of Candida albicans between the specimens. It is considered that the setting of the build angle should be set considering the accuracy or strength rather than the roughness of the surface.

The purpose of this thesis is to dedicate to get the objectivity of herbal medicine treatments by choosing herbs likely to work as antifungal agents against Candida albicans which is the causes of Candida vaginitis, making experiments on them and getting the significant results. Each herb's efficacy on control the number of Candida vaginitis is noticed by using Disk Susceptibility test with six herbs medicine and Broth dilution assay of the culture. Cinamon Ramulus, Pulsatillae Radix, Dictamni Radicis Cortex, Paeoniae Radix, Arecae Semen, Artemisiae Capillaries Herba extracts experimented on the efficiency of antifungal activities against Candida albicans by disk susceptibility test. Pulsatillae Radix has the strongest efficiency. In Dictamni Radicis Cortex never appeared antifungal effect on treatment. MIC (minimal inhibition concentration) in vitro antifungal agents of Cinamon Ramulus, Pulsatillae Radix, Paeoniae Radix, Artemisiae Capillaries Herba extracts against Candida albicans was determined by broth dilution assay. MIC against Candida albicans is that Pulsatillae Radix is 2.5 mg/ml and Cinamon Ramulus is 5 mg/ml and Paeoniae Radix is 10 mg/ml and Artemisiae Capillaries Herba is 40 mg/ml.

충남 서천군 한산면 신성리 금강하구 갈대밭 토양의 야생효모 분포특성을 알아보기 위하여 갈대밭 토양 20점을 채취하여 야생효모들을 분리하여 총 11종 20균주의 야생효모를 동정하였다. Candida속의 효모가 10균주로 가장 많이 분리되었고, 그 중 Candida subhashii 균이 6균주로 가장 많았다. 분리된 균주 중에서 Candida tropicalis (Y5-1,Y5-2, Y6-1), Candida subhashii (J7-1, J7-3, J8-1, Y9-1, Y9-2, Y9-3), Lachancea thermotolerans (MJS 007, MJS 019) 균주 등 12균주들이 알코올 발효능을 보였다. Bullera japonica YJ10-1, C. subhashii J7-1, Kluyveromyces yarrowii YJ11-1, Ustilago shanxiensis Y10-1등 4균주들이 국내 미기록 효모 균주들로 최종 선별되었다. 이들 국내 미기록 균주들은 구형으로 Candida subhashii J7-1만이 자낭포자와 의균사를 형성하였다. Kluyveromyces yarrowii YJ11-1은 비타민을 함유하지 않은 배지에서도 생육하였고 Candida subhashii J7-1는 YM과 YPD 배지 및 5% NaCl을 함유한 YPD 배지에서 생장하지 않았다.

대전광역시 연자산과 충청남도 주요 산림 토양들로부터 분리, 동정한 야생효모들 중 국내 미기록종으로 Pseudozyma prolifica HL9-1, Trichosporon coremiiforme NS19-2, Candida cretensis SA4-1, Cryptococcus diffluens TJ4-3, Cryptococcus pinus YB17-2 등의 유포자효모와 Candida vartiovaarae DD2-5, Pichia galeiformis DM3-5, Candida pseudolambica JW2-3, Trichosporon xylopini NS5-1, Trichosporon moniliiforme NS5-7, Tetrapisispora iriomotensis NS14-2, Tetrapisispora nanseiensis SA17-1 등의 무포자효모들을 선별하여 이들의 미생물학적 특성을 조사하였다. 12균주 모두 구형~타원형이었고 출아법으로 영양증식하였으며 yeast extract peptone dextrose (YPD) 배지에서 잘 생육하였다. 특히 Candida cretensis SA4-1과 Tetrapisispara iriomotensis NS14-2은 10% NaCl을 함유한 YPD 배지에서 잘 생육하는 호염성 효모들이었다. Candida vartiovaarae DD2-5외 3균주들은 유당을 자화시켰으며 Tetrapisispora nanseiensis SA17-1은 xylose를 자화시키고 동시에 발효시켰다. Candida cretensis SA4-1과 Tetrapisispara iriomotensis NS14-2 두 호염성 효모들의 생리기능성을 조사한 결과 이들의 무세포추출물들의 항고혈압성 안지오텐신 전환효소 저해활성이 각각 71.3%와 68.4%로 높았다.

We have evaluated the combined antifungal effects of the essential oil from Eucalyptus globulus or its main component 1,8-cineole with ketoconazole. Checkerboard microtiter tests were used to analyze their effects against three Candida and six Trichophyton species. The susceptibility of the Trichophyton species to E. globulus essential oil differed distinctly. The fractional inhibitory concentration indices (FICIs) against the tested Candida species ranged between 0.09 and 0.38 for ketoconazole combined with E. globulus essential oil or 1,8-cineole, indicating significant synergism between ketoconazole and the oil samples. Similar experiments using Trichophyton species resulted in FICIs between 0.28 and 0.63, indicating relatively weaker combined effects than those observed with Candida species. Thus, the data reported here show that the anti-Candida effects of ketoconazole can be significantly improved in the presence of E. globulus essential oil or 1, 8-cineole.

This study aimed to explore whether photodynamic therapy using Radachlorin and diode laser is an effective inhibitor of Candida albicans. Suspensions of Candida albicans were obtained, inoculated in petri dishes with Radachlorin, and incubated for 30 min. Then, the laser light of a diode laser was irradiated at at energy densities of 3 J/cm², 5 J/cm², 7 J/cm². As a result, Candida albicans showed a killing rate of 91.5% at an energy density of 7 J/cm². This study found that photodynamic therapy using a Radachlorin and diode laser was effective for the inhibition of Candida albicans.
