Facial vertical dyscrepancies is decided on the relationship between the anterior vertical facial height and posterior vertical facial height. Thus this study was conducted to determine the factors that affect the FHI, and classify the Class II div.1, malocclusion, which success is dependent on the vertical control according to the FHI, which is the ratio of antero-inferior facial height, posterio-inferior facial height ratio, and to use this as a guideline for treatment. Angle between palatal plane and Mandibular plane were in the order of RH, ID. Thus showing that interrelated angle was more inportant than the independent angle of both, palatal plane and Mandibular plane. The tendency of Cl II div.1. Malocclusion according to FHI, showed the Low group to have Mx. protrusion, prominent development of Mn. ramus, and the Mn. body length and ant. post. position was normal. The Normo group showed slight protrusion of the Maxilla,. The development of the ramus was less than normal and the Mn. was in a slight retruded position. The High group showed the Mx. in a normal position, the development of the Mn. ramus and body was the lowest, and the Mn. was in a posterior position. In observation of the factors affecting the FHI between each groups of Cl II div.l, malocclusion; In the Low group the MP- PP angle was very small, the ID was smililar to the normal group, but the RH was very large thus the FHI was increased. In the Normo group, the PP-MP angle was normal, ID was slightly smaller than the normal group and the RH was slightly smaller than the normal group, thus maintaining a normal FHI ratio. In the High group the PP-MP angle was very large, the ID was similar to the normal group, but the RH was smaller than the normal group thus the FHI was small.

Aims: Several cockroach and ant species have been revealed to infest households with inadequate insect control and food storage practices. These household insects harbor countless bacteria species of public health, agricultural and industrial importance. Many studies have reported disease-causing bacteria from both cockroaches and ant’s species collected from hospitals and residential areas. The aim of this study was to characterize the culturable bacterial communities of two common household insects, big headed ants (Pheidole rugaticeps) and American cockroaches (Periplaneta americana) using 16S rRNA genes sequencing. Methodology and results: A total of 64 bacterial sequences were obtained from P. rugaticeps (48.44%) and P. americana (51.56%) and Firmicutes was the most dominant phylum from both insect species. Bacillus was the most dominant bacterial genus from both cockroach and ant samples. Other important genera isolated were Pseudomonas and Stenotrophomonas which have previously been suggested to have members that are of biotechnological importance. Food poisoning bacterial species, B. cereus and other bacterial strains such as B. subtilis, Acinetobacter baumannii, Burkholderia cepacia, P. aeruginosa, Staphylococcus epidermidis, Serratia marcescens and S. pseudintermedius with the history of human infections were isolated from some of the insect’s specimens. Conclusion, significance and impact of study Thus, these household insect pests harbor bacterial species known to cause diseases of serious public health importance that needs serious attentions. Similarly, the insects harbor other bacteria species that may provide opportunities for biotechnological exploration.

The present study was designed to identify the sequential electrophysiological findings ant to determine the prognostic values of electrophysiological and clinical pararneters in patients with Guillain-Barre syndrome (GBS). Severely affected 42 subjects (Grade D,E). Who fulfilled the diagnostic criteria of GBS were selected. Twentynine patients were followed up at least 6 months (range 6-24 months) from the onset of neurologic syrnptorns. We analyzed 83 electrodiagnostic studies from 42 subjects. The sequential electrophysiological abnorrnalities were most marked at 3-4 weeks after the onset. At that time the most significant change was a decrease of CMAP amplitude. By stepwise discriminant analysis of several electrophysiological parameters, the three variables, of CMAP amplitude, distal conduction velocity; and F-wave latency were deterrnined to be significant pararneters. The accuracy of predicting the prognosis at 6 months was 82. 8%, when the classification functions were applied. Nlerefore the findings of early electrophysiological studies would be irnportant in understanding the serial pathophysiological changes and assessing the clinical outcorne of Guillain-Barre syndrorne.

This study was undertaken to investigate the changes of tooth contacts following orthodontic treatment, using T-Scan system. Occlusal contacts in maximum intercuspation were examined in 26 patients at the end of the active phase of orthodontic treatment and again 3 months into the retention phase to assess the initial posttreatment occlusal changes. The obtained results of this study were as follows: 1. The mean total number of contacts increased from 11.27 at the end of orthodontic treatment to 13.15 at the follow up visit, which was found to be statistically significant (P<0.05). 2. The change of number of contacts on anterior teeth was unchanged. 3. The change of number of contacts on posterior teeth was found to be statistically significant (P<0.01). 4. The change of total number of teeth in contact was significant (P<0.05). 5. The number of ant. teeth in contact was slightly increased. but Which was not found to be statistically significant (P>0.05). 6. The number of post. teeth in contact significantly increased, which was statistically significant (P<0.05). 7. A statistically significant relationship was found between the total number of contacts at the end of treatment and the change in the contacts over time. The fewer the number of tooth contact was at the end of orthodontic treatment, the greater number of tooth contact increased over time(r=-0.38, P<0.05).

INTRODUCTION: A cyst is a closed pathologic sac containing fluid or semi-solid material in central region. The most common conventional treatment for a cyst is enucleation. It was reported that spontaneous bone healing could be accomplished without bone grafting. We are trying to evaluate bone reconstruction ability by analyzing panorama radiograph and computed tomography (CT) scan with retrograde studying after cyst enucleation. In this way we are estimating critical size defect for spontaneous healing without bone graft. MATERIALS AND METHODS: The study comprised of 45 patients who were diagnosed as cysts and implemented enucleation treatment without bone graft. After radiograph photo taking ante and post surgery for 6, 12, 18, 24 months, the healing surface and volumetric changes were calculated. RESULTS: 1. Spontaneous bone healing was accomplished clinically satisfying 12 months later after surgery. But analyzing CT scan, defect volume changes indicate 79.24% which imply incomplete bone healing of defect area. 2. Comparing volume changes of defect area of CT scan, there are statistical significance between under 5,000 mm3 and over 5,000 mm3. The defect volume of 5,000 mm3 shows 2.79x1.91 cm in panoramic view. CONCLUSION: Bone defects, which are determined by a healed section using a panoramic view, compared to CT scans which do not show up. Also we can estimate the critical size of defects for complete healing.

Spigelian hernia is an uncommon hernia of the ant. abdominal wall. Because of its insidious nature and nonspecific physical findings, the diagnosis of this hernia is often not made. Typically, the hernia orifice is small, and strangulation of the contents of the hernial sac can occur. Computed tomography permits the distinction between Spigelian hernia and other anterial abdominal wall or intraabdominal masses. Spigelian hernia requires surgical correction to prevent complication of acute abdomen with strangulation or incarceration. The typical site of a Spigelian hernia is at the level of the semicircular fold of Douglas known as the arcuate line. Spigelian hernia can occur above the umbilicus, high Spigelian hernia, but its very unusual site. We report a case of Spigelian hernia on upper abdomen and review the literature.

OBJECTIVE: Many applications such as biomedical signals require selecting a subset of the input features in order to represent the whole set of features. A feature selection algorithm has recently been proposed as a new approach for feature subset selection. METHODS: Feature selection process using ant colony optimization (ACO) for 6 channel pre-treatment electroencephalogram (EEG) data from theta and delta frequency bands is combined with back propagation neural network (BPNN) classification method for 147 major depressive disorder (MDD) subjects. RESULTS: BPNN classified R subjects with 91.83% overall accuracy and 95.55% subjects detection sensitivity. Area under ROC curve (AUC) value after feature selection increased from 0.8531 to 0.911. The features selected by the optimization algorithm were Fp1, Fp2, F7, F8, F3 for theta frequency band and eliminated 7 features from 12 to 5 feature subset. CONCLUSION: ACO feature selection algorithm improves the classification accuracy of BPNN. Using other feature selection algorithms or classifiers to compare the performance for each approach is important to underline the validity and versatility of the designed combination.

The hypersensitive reactions to ant stings vary from local to systemic. Because repeated stings may induce severe skin reactions or serious systemic allergic reactions, the concerns about minor skin reactions by ant stings have been increasing. A 34-year-old man was stung on the right forearm by an ant. He experienced erythematous papules with pain, burning and dyspnea. The stinging ants collected from the patients skin and the ants resident in his garden were identified as Brachyponera chinensis.

Removal of subgingival calculus is essential for the success in periodontal treatment. Subgingival instrumentation is used for the removal of all bacterial plaque and calculus. In this study, two types of anterior curet were used on ant. teeth to conduct subgingival scaling and root planing. The remaining amount of calculus was evaluated according to type of instrument, depth of pocket, and tooth surface. 24 teeth extracted from patients being treated at Dan Kook University dept. Perio. were used. 4 surfaces per tooth a total of 96 areas were evaluated. 12 teeth treated with Gracey No. 1-2 was used as the control group and 12 teeth treated with Mini-five curet No. 1-2 was the experimental group. The 4 surfaces of the teeth(buccal, mesial, lingual or palatal, distal) were observed under a stereomicroscope and the images were captured 3 times per surfaced with a CCD. The image were observed on the monitor using a 10 x 10 grid produced with the Microsoft power point. The amount of calculus remaining was evaluated 3 times per surface. The results were as follows. 1. There was no significant difference in remaining calculus according to the pre-treatment pocket depth, and tooth position(Mx. or Mn.). 2. The Mini-five curet showed better results than the Gracey curet but there was no statistically significant difference. 3. In both Gracey curet group and Mini-five curet group the lingual(or palatal) surface showed significant difference compared to the other surfaces(p < 0.05). From the results above, it is thought that when treating ant. teeth consideration of the tooth surface is more important than the choice of instrument.
