Electrocardiograms in rats fed diets with boiled eggs for 30 days was investigated. Amplitudes of P,Q and R waves were not significant differences among treatment groups. Amplitude of S wave in rats fed the diet with 95% boiled eggs was significantly tended to be increased compared with other groups(P<0.05). Amplitude of T wave in the rats fed the diet with 0% boiled eggs showed the highest values, and there were significant difference among treatment groups fed diets with 0% boiled eggs, 25% and 95% boiled eggs (P<0.05). Durations of P and PQ(PR) waves were high in the rats fed diets with 25% and 50% boiled eggs (P<0.05). Duration of QRS complex showed low in the rats fed diet 0% boiled eggs but not significant difference among treatment groups. Duration of QT was high in the rats fed diet with 0% boiled eggs(P<0.05). This result is assumed that electrocardiograms in the rats is not changed to intake the boiled eggs.

This study was conducted to determine the effect of sublethal concentrations ($LC_{10}$ and $LC_{30}$) of insecticides on pupal duration, emergence, adult longevity and oviposition of tobacco cutworm, Spodoptera litura Fabricius, when 3rd instar larva of tobacco cutworm was treated with insecticides of chlorpyrifos, ethofenprox, chlorfenapyr-bifenthrin and hexaflumuron-chlorpyrifos . Pupal duration of female and male were 6.9 days and 8.0 days at untreatment, and were 7.2 to 7.6 days and 8.3 to 8.6 days at insecticide treatment, respectively. Thus pupal duration at the insecticide treatment was slightly longer than that at the untreatment, and that of the males was slightly longer than that of the females even though significant difference between sublethal concentrations and among insecticides was not observed. Percent mergence was 88％ at untreatment and ranged from 79％ to 95％, in particular which showed above 91％ treated with chlorfenapyr-bifenthrin and ethofenprox, at insecticide treatment. Adult longevity was 7.7 days and 7.9 days for female and male at untreatment respectively, and 7.1 to 8.4 days for female and 7.7 days to 9.0 days for male at treatment. There was a significant difference between insecticides and sublethal concentrations of insecticides except showed the longest adult longevity at hexaflumuron-chlolfyrifos treatment. Total number of eggs laid were less at treatment (778-948) than that (1,010) at untreatment regardless of sublethal concentrations of insecticides. Accordingly the pupal duration and oviposition of tobacco cutworm were affected at the insecticide treatment of sublethal concentration.

Objective: This study was performed to investigate buccal facial depth (BFD) changes after extraction and nonextraction orthodontic treatments in post-adolescent and adult female patients, and to explore possible influencing factors. Methods: Twelve and nine female patients were enrolled in the extraction and nonextraction groups, respectively. Changes in BFD in the defined buccal region and six transverse and two coronal measuring planes were measured after registering pretreatment and posttreatment three-dimensional facial scans. Changes in posterior dentoalveolar arch widths were also measured. Treatment duration, changes in body mass index (BMI), and cephalometric variables were compared between the groups. Results: BFD in the buccal region decreased by approximately 1.45 mm in the extraction group, but no significant change was observed in the nonextraction group. In the extraction group, the decrease in BFD was identical between the two coronal measuring planes, whereas this differed among the six transverse measuring planes. Posterior dentoalveolar arch widths decreased in the extraction group, whereas these increased at the second premolar level in the nonextraction group. The treatment duration of the extraction group was twice that of the nonextraction group. No differences were found in BMI and Frankfort horizontal-mandibular plane angle changes between the groups. BFD changes in the buccal region moderately correlated with treatment duration and dental arch width change. Conclusions: BFD decreased in adult female patients undergoing extraction, and this may be influenced by the long treatment duration and constriction of dentoalveolar arch width. However, nonextraction treatment did not significantly alter BFD.

Object: We evaluated the efficacy of chest physical therapy in pediatric patients with pneumonia. Method: Retrospective study was performed in 89 pneumonia patients admitted to pediatric unit. The subjects were divided into two groups: control group; treatment group. Control group included 42 patients who didn't receive chest physical therapy. Treatment group included 47 patients who received chest physical therapy. The chest physcial therapy employed were postural drainage, chest percussion, deep breathing training and enhancement of coughings. The efficacy was evaluated by x-ray outcome before discharge. Results: There were no significant difference in age, sex, type of pneumonia, and symptom duration between two groups. However the duration of fever after admission, duration of antibiotic use and hospital stay were longer in treatment group. In treatment group, longer the day to initiate chest physical therapy, longer the hospital stay. The final outcome was not different between groups. Conclusion: The results suggest that the referred patients for chest physical therapy tends to be of severe cases. Nevertheless, the result that the outcome was not different in two groups means that the chest physical therapy could be used as a effective treatment method in pediatric patient with pneumonia.

Objective: This study was performed to investigate the effect of acupuncture at HT8 on brain activity in perimenopausal women using fMRI. Methods: 15 healthy perimenopausal women volunteered in the study. No stimulation, sham stimulation, duration of acupuncture treatment on HT8, and rotation of acupuncture treatment on HT8 were randomly given for 6 minutes, with 20 seconds' intervals. Results: 1. In comparison with sham stimulation(Sham-B) and duration of acupucture (S1-B, S1-Sham, S2-S1), the areas of fMRI signal activation areas were just like cases including no stimulation. But the areas of vision were activated in S1-Sham. 2. In comparison with duration of acupuncture(S1-B, S1-Sham, S2-S1) and rotation of acupuncture(S2-B, S2-Sham, S2-S1), the areas of vision were activated in duration of acupuncture, and Supplementary motor area(SMA) were especially activated in rotation of acupuncture. Conclusions: After using fMRI and analysing effect of acupuncture treatment at HT8, we could confirm that fMRI signal activation areas by acupuncture treatment at HT8 were different from areas by sham stimulation. And according to acupuncture stimulation methods with duration and rotation, etc, we could confirm the specific reactions of series, and could get useful basic data for research of acupuncture from now on.

Broiler chickens were subjected to (i) pre-treatment for 24 h with 1,200 ppm L-ascorbic acid in their drinking water on day 42 (AA), (ii) 60% feed restriction on days 4, 5 and 6 (FR), (iii) combination of AA and FR (AAFR), or (iv) neither treatment (control). On day 43, the birds were crated and transported in an open truck for either 60 min or 120 min. Heterophil/lymphocyte ratios (HLR) were determined prior to ($T_0$) and 20 h following the 60 min ($T_60$) and 120 min ($T_120$) journeys. Prior to transportation, all treatment groups had similar HLR. Following $T_60$, the AAFR chicks had smaller increase in HLR than their control, AA and FR counterparts. The AA, FR and AAFR birds exhibited lower HLR than controls following $T_120$. The means HLR of AA, FR and AAFR did not differ significantly. Irrespective of journey time, AA and AAFR birds had shorter tonic immobility duration than their FR and control counterparts. The tonic immobility duration of all birds increased with journey duration.

Background: The objective of the present study was to examine the status of patients who had received dental treatment under intravenous (IV) sedation at Chungnam Dental Clinic for the Disabled in Korea from its inception to the present time, and to review the analysis results. Methods: Retrospective analysis was performed on 305 cases of patients who had received dental treatments under IV sedation between January 2011 and May 2016. The analysis examined the patient's sex, age, primary reason for IV sedation, duration of anesthesia and dental treatment, type of dental treatment performed, number of clinical departments involved in the dental treatment and level of multidisciplinary cooperation, and annual trends. Results: Most dental treatments using intravenous sedation were performed on medically disabled patients or dentally disabled patients with an extreme gag reflex or dental phobia. The mean duration of IV sedation was 72.5 min, while the mean duration of treatment was 58.0 min. The types of dental treatments included surgical treatment (n = 209), periodontal treatment (n = 28), prosthodontic treatment (n = 28), restorative treatment (n = 23), implant surgery (n = 22), endodontic treatment (n = 9), reduction of temporomandibular joint dislocation (n = 1), and treatment of traumatic injuries (n = 1), with treatments mostly performed on adult patients. Conclusions: With increasing demand for minimally painful treatment, cases using IV sedation are on an upward trend and are expected to continue to increase.
