Objectives : The aims of this study were to investigate the psychopathology in adolescents with internalizing disorder using the self-report version of Strengths and Difficulties Questionnaire (SDQ-SR) and the Minnesota Multiphasic Personality Inventory for adolescents (MMPI-A), and to explore the complementarity between these two inventories for diagnostic assessment. Methods : Ninety-one patients aged 13-17 were divided into two groups by clinical diagnosis, 44 with internalizing disorder and 47 comparison group with other disorders. The data of SDQ-SR and MMPI-A completed by them were analyzed for the ability to predict internalizing disorder. Results : The logistic regression analysis revealed that diagnostic predictability increased by 2.27 times with every 1 point of SDQ-SR emotional symptom score increment. Comparison of ROC curves for internalizing disorders showed that the SE and SP of SDQ-SR emotional symptom with score over 4 was 88.94 and 78.72, respectively. For A-anx of MMPI-A with score over 56, SE and SP was 77.27 and 74.47, respectively. However, combination of these scales could not enhance the predictability of diagnostic classification more than that of SDQ-SR emotional symptom alone. Conclusions : Emotional symptom scale of SDQ-SR and A-anx, A-aln, A and INTR of MMPI-A should be important subscales for diagnosing the internalizing disorder of adolescents, however, which needs to be examined further with a larger sample size including normal control group.

Objectives : This study examined the characteristics and differences of PAI(Personality Assessment Inventory) profile between compensation-seeking(CS) and treatment-seeking(TS) patients with traumatic brain injury(TBI) and assessed the clinical meaning of the characteristics and differences of profiles between the two groups. Methods : 36 TBI patients who visited the Wonkwang University Hospital were selected. The patients were categorized as compensation-seeking TBI patients(n=22) and treatment-seeking TBI patients(n=14). The PAI scales and subscales were used to compare differences between two groups. t-verification for each variable and comparison analysis were performed. Results:In validity scales, CS group showed significantly higher NIM scores and lower PIM scores than TS groups. In full scales, CS group showed significantly higher SOM, ANX, ARD, DEP, and SCZ scores than TS group. In subscales, CS group showed significantly higher SOM-S, ANX-A, ARD-P, DEP(-C, A, P), (MAN-I), PAR-H, SCZ(-T, P), BOR(-A, N), and ANT-S scores than TS groups. In supplementary scales, CS group showed significantly higher SUI, NON and AGG-P, and lower RXR scores than TS group. Conclusions:There were significant differences in PAI scales with validity scales, some full and subscales according to compensation seeking status in TBI patients. The CS patients tended to exaggerate their symptoms on PAI, and showed higher scores representing somatic preoccupation and emotional distress. These results show the usefulness of PAI in reflecting the significant psychological differences between two groups.

Food intake is regulated by both central and peripheral mechanisms. In the central nervous, the hypothalamus acts for autonomic and endocrine homeostasis. The paraventricular nucleus(PVN) of hypothalamus is an imprtant site of interaction in central feeding pathways. Neuroepetide Y(NPY)is one of the most powerful neurochemical stimulants of food intake known. Also brain nitric oxide(NO), known as neurotransmitter, is involved in the mechanisms that regulate food intake. In this experiment, 24h fasting mice and anorexia mutant mice have been to examine the expression of NPY, which is the major neuropeptide increasing food intake. Double staining with NPY and nicotinamide-adenine-dinucleotide-phosphate diaphorase(NADPH-d), followed by immunohistochemical method and image analysis, have been used to observe coexisting neurons and the level of expression of each neurons. The results were as follows. 1) NPY-immunoreactivitys reduced immune response of the hypothalamus, particularly paraventricular nucleus(PVN), in anorexia mutant mice. Decreased level of NPY is assumed to be a major pathological factor in anorexia mutant mice. On the other hand, PVN in hypothalamus of fasting mice showed increased immunoreactivity which is in agreement of other researchers. 2) NPY and NADPH-d double staining revealed coexisting neurons in the cerebral cortex. Fasting mice had a tendency to have increased level of coexisting neurons compared to the control group. Compared to the control group, fasting mice express is not increase level of NPY-immunoreactivity, while anorexia mutant mice tended to have a decreased level.

Purpose: The purpose of this study was to assess influences of psychological factors on sleep disturbances in young adults through the revised version of the Minnesota Multiphasic Personality Inventory (MMPI-2). Methods: Two hundred and ninety nine college students in Gyeonggi-do completed the MMPI-2 and a questionnaire related to sleep disturbances and collected data were analyzed by logistic regression. Results: The odds of tooth grinding increased significantly with the increase of T-score of hysteria (Hy) scale. The increase of T-score of hypomania (Ma) and social introversion (Si) scale significantly contributed to the risk of insomnia. The occurrence of insomnia increased significantly as T-score of somatic complaints (RC1) and psychoticism (PSYC) scale increased. The odds of tooth grinding increased significantly as T-score of anxiety (ANX) and family problems (FAM) scale increased. The occurrence of insomnia decreased significantly with the increase of T-score of type A behavior (TPA) scale. The increase of T-score of dominance (Do) scale significantly contributed to the risk of tooth clenching. The odds of tooth grinding decreased significantly as T-score of MacAndrew alcoholism-revised (MAC-R) scale increased, whereas it increased significantly as T-score of addiction potential scale (APS) increased. No scale of MMPI-2 significantly affected the occurrence of snoring. Conclusions: T-scores of Hy, ANX, FAM, Do, MAC-R, and APS scales on MMPI-2 affected the risk of bruxism. T-scores of Ma, Si, RC1, PSYC, and TPA scales on MMPI-2 influenced the occurrence of insomnia. The psychometric instrument such as MMPI-2 is helpful in understanding and managing bruxism and insomnia.

The present study was conducted to identify the mechanism about the regulation of appetite by examining the expression patterns of vasoactive intestinal peptide in the hypothalamus of either fasted for 24 hours or anorexia mutant mouse. In order to investigate expression pattern of the vasoactive intestinal peptide, immunohisto-chemistry was employed along with reverse transcription polymerase chain reaction (RT-PCR) and dot blotting. Immunohistochemistry has shown that level of expression of vasoactive intestinal peptide and appetite-suppessing neuropeptide, was lower in the suprachiasmatic nucleus (SCN) and higher in the paraventricular nucleus (PVN) of the anorexia mutant group than in the comparable regions in the control group. This pattern was repeated in the fasting group, which also showed lower and higher levels of vasoactive intestinal peptide expression in the SCN and PVN respectively, In contrast, the vasoactive intestinal peptide mRNA level in the entire hypothalamus via RT-PCR and dot blotting was similar in the fasting and control groups, while it was significantly increased in the anorexia mutant group.

The mentophysical disease causes diseases in digestive, respiratory, circulating systems, including chronic pain, through combined reactions from different individual characteristics, mental stress and temperamental factors. The most common symptom related to orofacial area is pain and the contributive factors include biological, behavioral, environmental, social, emotional, recognitive factors. These factors affect the course of the symptom according to individual's character and human nature. In pain, sleep acts as a contributive factor, and pain could bring about sleep disturbance and vice versa. Deterioration of sleep quality would act as a factor that aggravates mental stress. Therefore, relatively accurate and simple mental examinations and sleep quality test should be carried out for the patients with symptoms related to orofacial area. This study evaluated the mental state in relation to the sleep quality which could affect orofacial pain. The number of poor sleeper was 18 in male subjects, and 1 in female subjects and PSQI global index was higher in male($6.11{\pm}2.38$) than female($4.67{\pm}2.18$). SCL-90-R index showed no sex difference. Poor sleeper showed significantly high value in SOM, O-C, I-S, ANX, PHOB, PSY, GSI, PST. When SCL-90-R T scores were compared according to sleep quality, higher the subjective sleep quality score, O-C and I-S showed significant increase. As sleep disturbances score increased, PAR, PSY, PST showed statistically significant increase. In comparison of SCL-90-R T score according to daytime dysfunction, statistically significant increase in DEP, ANX, HOS, PHOB, PAR, GSI was observed. Therefore, the quality of sleep and psychological status have a high correlation. This is likely to influence chronic pain in the orofacial field. As a result, clinicians treating orofacial pain should evaluate the sleep quality and psychological status of the patient. Further studies of larger sample sizes including various age, occupation, and pain groups are necessary in order to apply the results to clinical practice.

The present study was conducted to investigate gene expression profile of mouse ovaries during the primordial-primary follicle transition. We isolated total RNA from mouse ovaries at day1(contains only primordial follicles) and day5(contains both primordial and primary follicles) and synthesized cDNA using annealing control primers(ACP, Seegene, Inc., Seoul, Korea). Using 80 different ACPs for PCR, we cloned, sequenced, and analyzed identities of 41 differentially expressed genes(DEGs). According to BLAST analysis, sequences of 33 clones significantly matched database entries, 4 clones were novel, and 4 clones were ESTs. We selected 8 DEGs with interesting functions, Anx11 and Pepp2-Pending highly expressed in day1 ovary, while Apg3/Autlp-like, BPOZ, Ches1, Kcmf1, NHE3, Nid2, Ninj1, SENP3, Suil-rsl, and TIAP/m-survivin highly expressed in days ovary, and confirmed their different expression between day1 ovaries and days ovaries using semi-quantitative RT-PCR. There was no false positive result. Using in situ hybridization, we found that almost all of genes studied were expressed in the oocyte from primordial follicle stage but expression decreased from primary follicle stage. Meanwhile their expression was increased in cuboidal granulosa cells. Different expression of BPOZ and TIAP/m-survivin between primordial and primary follicles was confirmed by using laser capture microdissection followed by real-time PCR BPOZ and TIAP/m-survivin expressed 4.5 and 3.4 fold higher in primary than primordial follicles, respectively. List of genes obtained from the present study will provide insights for the study of mechanism regulating primordial-primary follicle transition.

This study was intended to verify that the Revised PAI-A scale reflected the internalization and externalization classification of adolescence problem behavior. For this purpose, exploratory factor analysis and confirmatory factor analysis were conducted using PAI-A restandardization data. In addition, 31 Revised PAI-A sub-scales and SUI scale were used to identify the detailed factor structures. As a result of the analysis, the classification of internalization and externalization factors was similar to that of previous studies. In detail, the sub-scales of ANX·DEP and SUI were classified into internalization, the sub-scales of ANT and AGG were classified into externalization. It is noteworthy that each sub-scale of PAI-A was separated into internalization or externalization. For example, BOR-A, BOR-I, and BOR-N were loaded into internalization, but BOR-S into externalization. Next, in order to confirm whether the structure of the derived internalization and externalization factors can be applied to new samples, 350 samples were randomly extracted and confirmatory factor analysis was conducted, but exclusive of the samples used for exploratory factor analysis. As a result of confirmatory factor analysis, the appropriate indices of internalization and externalization classification was close to the good level. Therefore, the Revised PAI-A scales have theoretical relevance to internalization and externalization classification of problem behaviors. Based on the results of this study, it is expected that it can be used helpfully in the school settings in the future. Finally, the significance and limitations of this study were discussed.
