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).

OBJECTIVES: This study was carried out to determine whether or not pine needles can be used as passive samplers of atmospheric polycyclic aromatic hydrocarbons (PAHs) using the correlation between accumulated PAH concentrations in air (Ca, ng/m3) and those deposited on pine needles (Cp, ng/g dry). METHODS: PAHs in ambient air was collected using low volume PUF sampler and pine needles was gathered at same place for 7 months. RESULTS: good correlation (R2=0.8582, p<0.05) was found between Ca and Cp for PAHs with a higher gaseous state in air (AcPy, Acp, Flu, Phen, Ant, Flt, Pyr, BaA and Chry), but there was a poorer correlation (R2=0.1491, p=0.5123) for the PAHs with a lower gaseous state (BbF, BkF, BaP, DahA, BghiP and Ind123). A positive correlation (R2=0.8542) was revealed between the logarithm of the octanol-air partitioning coefficient (logKoa) and Cp/Ca for the PAHs with a higher gaseous state in air, but there was a negative correlation (R2=0.8131) for the PAHs with a lower gaseous state. The Ca-Cp model could not be used to estimate PAHs concentrations in air using deposited PAHs concentrations on pine needles, but the logKoa-Cp/Ca model could be used. CONCLUSIONS: It was found that pine needles can be used as passive samplers of atmospheric PAHs.

Reactions from stinging insects are significant to dermatologists because of the wide variety of clinical presentations from mild local reaction to severe anaphylactic reaction. Although ant sting commonly occurs, it has been rarely reported in the literatures. We experienced a unique case with allergic reactions by the ant of the Cremawgaster iw6w urai vagala, subfamily Myrmicinae, family Formicidea, order Hymenoptera that has not been previously reported.

The ghost ant Tapinoma melanocephalum is a common household pest worldwide. The present study examined the occurrence of the species in urban homes in Korea. During the period of September 2014 to January 2016, T. melanocephalum workers were collected from 58 homes at 29 different localities using bait traps with 10% sugar solution. The species was widely distributed throughout urban homes at 29 different localities, and the indoor occurrence of T. melanocephalum was highest in Seoul (32.7%) and metropolitan areas of Gyeonggi-do (Province) (29.3%). The indoor incidence rate of T. melanocephalum peaked in September (22.8%), remained moderate from October through April, and peaked again in May (15.7%). In contrast, a low incidence was observed from June to August (7.0%). The present study provides evidence that native ants, such as T. melanocephalum, are potential indoor pests of homes in Korea throughout the year.

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.

Authority estimated the concentration of fluorescein sodium in the blood, anterior chamber and vitreous after injection of 10% fluorescein sodium, 25mg/kg, according to the lapse of time. Also intravitreal fluorescein sodium concentration was measured after intravitreal injection of 0.1 % fluorescein sodium 10 micro liter according to the lapse of time. The results were as follows. 1. In the normal rabbits, the concentration of fluorescein sodium in the anterior chamber and vitreous were 159.3 +/- 101.7 X 10(-9) gm/ml and 3.6 +/- 4.7 X 10(-9) gm/ml, respectively after 1 hour of fluorescein sodium intravenous injection. The Cv/Ca was 0.02 +/- 0.028(Cv: concentration of fluorescein in the vitreous) (Ca: concentration of fluorescein in the ant. chamber). 2. After injection of sodium fluorescein in the normal rabbit, the concentration of fluorescein in the blood showed rapid decrease in logarithmic manner in the vitreous, the concentration peaked 1 hour and 2 hours after injection which persisted several hours. 3. The concentration of fluorescein sodium in the vitreous after intravitreal injection of fluorescein decreased at logarithmic rate which disappeared 24 hours after injection.
