OBJECTIVETo evaluate the aldose reductase inhibitory (ARI) activity of different fractions of Hybanthus enneaspermus for potential use in diabetic cataract.

METHODSTotal phenol and flavonoid content of different fractions was determined. ARI activity of different fractions in rat lens was investigated in vitro.

RESULTSThe results showed significant level of phenolic and flavonoid content in ethyl acetate fraction [total phenol (212.15±0.79 mg/g), total flavonoid (39.11±2.27 mg/g)] and aqueous fraction [total phenol (140.62±0.57 mg/g), total flavonoid (26.07±1.49 mg/g)] as compared with the chloroform fraction [total phenol (68.56±0.51 mg/g), total flavonoid (13.41±0.82 mg/g)] and petrolium ether fraction [total phenol (36.68±0.43 mg/g), total flavonoid (11.55±1.06 mg/g)]. There was a significant difference in the ARI activity of each fraction, and it was found to be the highest in ethyl acetate fraction [IC50 (49.26±1.76 µg/mL)] followed by aqueous extract [IC50 (70.83±2.82 µg/mL)] and it was least in the petroleum ether fraction [IC50 (118.89±0.71 µg/mL)]. Chloroform fraction showed moderate activity [IC50 (98.52±1.80 µg/mL)].

CONCLUSIONSDifferent fractions showed significanct amount of ARI activity, where in ethyl acetate fraction it was found to be maximum which may be due to its high phenolic and flavonoid content. The extract after further evaluation may be used in the treatment of diabetic cataract.

PURPOSE: Resonance Frequency Analysis(RFA) technique can be used as an effective method in measuring the implant stability and documenting the clinical results. This technique also determines how stable the implant is before performing a prosthetic practice. Having become one the guidelines of the implant therapy whose final objective is the immediate loading, the Osstell(TM) mentor is giving a lot of information to the clinicians recently. In this communication, experiments were performed to investigate how reliable the measured ISQ values by Osstell(TM) mentor are, and to see if those are also stable even after sterilization. As five objectives: 1) How stable measured ISQ values after fixation Smartpeg(TM)s for 400 times. 2) How stable measured ISQ values after 'attach-detach'Smartpeg(TM)s for 400 times. 3) How stable measured ISQ values after clinical sterilization methods. 4) How stable measured ISQ values after repeatedly sterilization in autoclave for 10 times. 5) What is the critical temperature which is lost the magnetism of Smartpeg(TM). MATERIALS AND METHODS: Clinical sterilization methods(Autoclave sterilization, Dentistar sterilization, Ultra violet sterilization, Vacuum dry unit sterilization, Boiling water sterilization, combined H(2)O(2) and Alcohol sterilization). Smartpeg(TM)s. D3 Block bone(3x9x2cm). Osstem implant(phi 4.1-10mm). Osstell(TM) mentor. Individual experiment was used 8 number of Smartpeg(TM)s and they had measured to ISQ values of before experiment and after experiment. RESULTS: 1. The measured ISQ values did not change after fixation Smartpeg(TM)s for 400 times. 2. There was no significant changes in the measured ISQ values of 'attach-detach Smartpeg(TM)s' for 400 times. 3. The measured ISQ values did not change after the usual clinical sterilization methods. 4. The measured ISQ values did not change after sterilization in autoclave for 10 times. 5. It was impossible to exactly measure the critical temperature which is lost the magnetism of Smartpeg(TM)s. But, the results was resulted to lost its magnetism in higher temperature than 150 degrees C/10 minute. CONCLUSION: The measured ISQ values showed insignificant differences in case of no changes in the magnetism of the Smartpeg(TM)s. It seems that the Smartpeg(TM)s can be used repeatedly in every measurement if the original magnetisms of the Smartpeg(TM)s can be recognized. There seems to be no significant changes in the measured ISQ values of 'attach-detach Smartpeg(TM)s' only if the screw pitches were unimpaired. The clinical sterilization methods seems acceptable because the result was resulted to lost its magnetism in higher temperature than 150 degrees C/10minute.

PURPOSE: To evaluate the utility of preoperative nidus localization guided by computed tomography(CT). MATERIALS AND METHODS: In the light of clinical, radiographic, and imaging findings, osteoid osteoma was suspected in all ten patients studied. An osteoid osteoma of the tibia was present in seven cases, and of the femur in three. During the 24 hours preceeding surgery, a small hole was drilled directly over the nidus with a 15gauge Ostycut bone biopsy needle, using CT for control and guidance. The hole and needle tract were stained with Gentian violet and GE 9800 and Hi Speed Advantage CT (GE) were used to obtain both 2D and 3D images. RESULTS: Each osteoid osteoma was in the cortex of the bone, nidi ranged in size from 10x6x6 to 40x7x9mm and the sclerotic area around each varied in size between 150x18x14 and 50x15x12mm. Marking was successful on the first attempt in eight cases, on the second attempt in one case and on the third attempt in one case. The average time per marking attempt was 15 minutes. In the operating field, stained marking on the cortex was easily found inall cases. With the marking it was possible to excise only as much of the bone as necessary and none of the ten patients suffered complications either during or after the procedure. The diagnosis of osteoid osteoma was histopathologically confirmed in all patients. CONCLUSION: CT guided nidus marking of an osteoid osteoma assured precise localization during surgery ; bone resection was therefore minimal and the time required for surgery was reduced. The procedure is a simple, safe, effective method for precise and easy nidus excision.

Several indices have been developed that use bleeding and color changes as indicators of early gingival pathology. In the presence of gingivitis, vascular proliferation and reduction of keratinization owing to increase redness in gingiva. Descriptions of healthy gingiva are numerous, ranging from pale pink and coral pink to deep red and violet. This terms are not objective. Because of perception of color depends on a lot of factors such as light source, object, observer and so on. It is difficult to make an objective expression. Therefore the using of mechanical equipment is recommended to exclude these variables and observer's vias. The purpose of this study was to evaluate gingival color change after scaling & subgingival root planing. The other purpose of this study was to research the correlation of pocket depth, P.B.I. score and gingival color change. After photo-taking and storaging the image of gingival color into a computer, color change was examine with an image analysis program. Results were as follow; 1. Color of healed gingiva after scaling & subgingival root planing was significantly differ from color of inflamed gingiva(p<0.01). 2. Color of healed gingiva after scaling was similar to color of healed gingiva after subgingival root planing(p<0.05). 3. There was statistically significant correlation between color change of red component and pocket depth after scaling & subgingival root planing(p<0.01) 4. There was no correlation between color change of green, blue component and pocket depth after scaling & subgingival root planing(p<0.01) 5. There was statistically significant correlation between between color change of red component and P.B.I. score after scaling & subgingival root planing(p<0.01). 6. There was no correlation between color changes of green, blue component and P.B.I. score after scaling & subgingival root planing(p<0.01) 7. Increase of pocket depth and P.B.I. score were significantly correlated to the amount of color change(p<0.01). 8. P.B.I. score had a higher correlation with color change than pocket depth(p<0.01).

In this study, we identified the causative agent of stem-end rot in potatoes that were grown in Gangwon alpine areas of Korea in 2013. The disease symptoms included appearance of slightly sunken circular lesion with corky rot on the potato surface at the stem-end portion. The fungal species isolated from the infected potatoes were grown on potato dextrose agar and produced white aerial mycelia with dark violet pigments. The conidiophores were branched and monophialidic. The microconidia had ellipsoidal to cylindrical shapes and ranged from 2.6~11.4 x 1.9~3.5 microm in size. The macroconidia ranged from 12.7~24.7 x 2.7~3.6 microm in size and had slightly curved or fusiform shape with 2 to 5 septate. Chlamydospores ranged from 6.1~8.1 x 5.7~8.3 microm in size and were present singly or in pairs. The causal agent of potato stem-end rot was identified as Fusarium oxysporum by morphological characterization and by sequencing the internal transcribed spacer (ITS1 and ITS4) regions of rRNA. Artificial inoculation of the pathogen resulted in development of disease symptoms and the re-isolated pathogen showed characteristics of F. oxysporum. To the best of our knowledge, this is the first study to report that potato stem-end rot is caused by F. oxysporum in Korea.
