Objectives : The purpose of the current study was to evaluate subject quality of life in depressed parents of boys with Duchenne/Becker muscular dystrophy (DMB/ BMD). In addition, a specific relationship between subject quality of life and the severity of depressive symptom was explored. Methods : The participants were 15 depressed parents who had moderate to severe depressive symptoms and 35 nondepressed parents of boys with DMD/BMD. All participants completed the World Health Organization Quality Of Life Scale, Brief Version and the Beck Depression Inventory. Other instruments included the Family Relationship Scale and the Child Behavior Checklist. Results : Among various model predictors, only higher score on the Beck Depression Inventory predicted lower scores on all domains of the World Health Organization Quality Of Life Scale, Brief Version. In addition, depressed parents had significantly lower scores on all domains of the World Health Organization Quality Of Life Scale, Brief Version including physical health, psychological health, social relationships, and environment, relative to non-depressed parents. Conclusion : Findings of the current study suggest that all domains of subjective quality of life may be influenced by depressive symptoms in parents of boys with DMD/BMD.

The present investigation was initially undertaken to see if there exists $Na^+-K^+$ activated ATPase in the microsome fraction of the kidney. Having confirmed the presence of such an enzyme, further attempts have been made to characterize its nature and the following conclusions were obtained: (1) The ATPase activity was greatest at the $Na^+$ concentration of 100 mM as well as at $K^+$ concentration of 10 mM. Moreover, the ATPase activity was found to be depressed by $Ca^{++}$ in the presence of $Mg^{++}$. (2) While the ATPase activity was depressed by Ouabain, the magnitude of inhibition was greater in the Na medium than in the K medium. (3) NaCN augmented the ATPase activity whereas NaF and IAA depressed it. On the other hand, DNP had little influence on the ATPase activity. (4) Diamox, vasopressin and aldosterone had no effect while $HgCl_2$ markedly depressed the ATPase activity These findings indicate that the nature of ATPase isolated from the microsome fraction of the rabbit kidney is quite similar to that from other organs such as the heart and the muscle, although there are certain features specific to the type of organs.

Lidocaine의 심근수축력 억제 작용에 관한 기전연구 일환으로 lidocaine에 의해 수축력이 감소된 흰쥐 적출심방에 대한 fructose의 효과를 검토하였다. Fructose는 기질제거에 의해 감소된 적출심방의 수축력을 현저히 증가시켰으며, 30mM에서 최대 증가효과를 나타냈다. Krebs-Ringer glucose용액에 현수한 적출심방의 수축력은 0.1mM lidocaine에 의해 약 50%의 감소를 나타냈으며, 30mM fructose의 투여는 이 감소된 수축력을 현저히 증가 시켰다. Lidocaine 억제심방에 대한 fructose의 실험 성적은 pyruvate나 acetate에서 얻은 실험성적과 유사하였다. 그러나 같은 농도의 fructose는 저 calcium(1/2)농도의 Krebs-Ringer glucose medium에서 감소(약 50% 감소)된 적출심방의 수축력을 증가시키지 못하였다. 이상의 결과에서 lidocaine은 심근내 포도당 대사를 해당과정에서 억제한다는 가능성을 재확인하고 있으며, 나아가서 lidocaine은 해당과정의 phosphofructokinase step 이전의 초기단계에서 억제하고 있을 가능성을 시사하고 있다.

Objective : Existing depression rating scales do not fully reflect depressed patients' perspective of remission, which goes beyond symptom resolution. The Remission from Depression Questionnaire (RDQ) captures a broader array of domains, and the present study examines the reliability and validity of the Korean Version of the RDQ (K-RDQ). Methods : The test-retest reliability of the K-RDQ was studied in 60 depressed patients and 30 normal subjects working at a university hospital. Subjects were evaluated at baseline and again 1-2 weeks later. The validity of the K-RDQ was studied in 200 depressed patients who were rated on the 17-item HDRS and the CGI-S ; each patient also completed the QIDS-SR, STAI-S, GHQ/QL-12, and SDS. Results : The K-RDQ demonstrated excellent internal consistency, with a Cronbach's ${\alpha}$ of 0.965 for the total scale and above 0.80 for each of the 7 subscales. The test-retest reliability of the total scale was 0.951. Mean K-RDQ scores ($45.79{\pm}18.65$) of the depressed patients were significantly higher than those ($15.87{\pm}10.60$) of the mentally healthy subjects (t=12.8, p<0.001). Five factors from the K-RDQ were extracted by principal axis factoring with equimax rotation. Conclusion : These results indicate that the K-RDQ is a reliable and valid measure that evaluates multiple domains that depressed patients consider important in determining remission. Thus, the K-RDQ maybe considered an appropriate tool for use in the clinical setting.

In this study, the influence of impurity element Ca, P on solidification behavior and morphology of eutectic silicon was examined by observation of microstructure and by DSC analysis. In the case of 1.3 ppm P, eutectic Si was fine and fibrous when the added amount of Ca was 500 ppm, However, the modification of eutectic Si was depressed by formation of polygonal Ca-Si compounds when the addition amount of Ca was greater than 1000 ppm. The addition of Ca 500 ppm depressed the primary and eutectic temperature. The primary and eutectic temperature were depressed with Ca 500 ppm but rather ascended when the addition amount of Ca was more than 1000 ppm. When the content of P was 17.5 ppm, eutectic Si had modified morphology with Ca addition. DAS was increased, the primary temperature was ascended and eutectic temperature was depressed with Ca added. Eutectic Si appeared as coarse flake phase and DAS was decreased with the increase of P content. The existence of P in the melt depressed the primary temperature and ascended eutectic temperature.

This research was designed to analyze the relationship among depression level, body cathexis, and clothing behavioral attributes of middle-aged women. Respondents for questionnaire were middle-aged women aged from 40 to 59. A total of 197 responses were analyzed by SPSS 21.0 through t-test, and factor analysis with Varimax rotation. The results were as following. As older, the portion of depressed group increased. Higher in depression level, her body cathexis decreased, meaning those two valuables have negative relationship. Six clothing behavioral factors were extruded: style pursuit, body shaping, showing-off, comfort pursuit, recreativeness, and consciousness of others factor, which covers both physical and psychological aspects of middle-aged women. The difference between 40's and 50's was significant in depression level, however, not significant in body cathexis and clothing behavioral attributes. Except for weight, body cathexis satisfaction level of 'depressed group' were significantly lower than 'not-depressed group', meaning that psychological factor give a significant effect on body cathexis. 'Not-depressed group' tend to choose her own style and 'depressed group' more likely to be conscious of others and conform to the affiliation group. This finding implies that design and coordination of garments for middle-aged women could be recommended according to the depression level to improve the quality of life.

Purpose: Contrary to the human study, it has rarely investigated metabolic alterations in the dorsolateral prefrontal cortex (DLPFC) of depressed rats versus age and sex-matched controls using proton magnetic resonance spectroscopy (MRS). Thus, the purpose of this research was to verify the feasibility of metabolic differences between the normal rat and the depression model rat. Materials and Methods: A homogeneous group of 20 SD male rats was used for MRI and in vivo 1H MRS. To induce a depressed status in SD rats, we performed the forced swimming test (FST). Using image-guide, water suppressed in vivo 1H MRS with 4.7 T MRI/MRS system, NAA/Cr and Cho/Cr ratios were mainly measured between depressed rats and normal subjects. Results: In depressed rats, increased Cho/Cr ratio was measured versus control subjects. However, no significant group effect for NAA/Cr was observed between case-control pairs. Discussion and Conclusions: The present 1H MRS study shows significant brain metabolic alterations of dorsolateral prefrontal cortex with experimental depressed status of SD rat induced by FST compared to normal subjects. This result provides new evidence that in vivo 1 H MRS may be a useful modality for detecting localized functional neurochemical markers alterations in left DLPFC in SD rats.

Background: Muscle mass and muscle function are related to depressed mood in studies of adults. Like adults, Korean students are highly likely to suffer from decreased muscle mass due to social conditions. In this study, we evaluated the muscle mass status of Korean adolescents and assess the effect of muscle on depressive mood. Methods: A total of 1,233 adolescent boys and girls participants from the Korea National Health and Nutrition Examination Survey were enrolled in our study. Participants underwent dual-energy X-ray absorptiometry for assessment of appendicular muscle mass and completed questionnaires regarding depressed mood, stress, suicidal ideations, and attempts. Results: There was no difference in depressive mood according to muscle mass among boys (P = 0.634); girls with decreased muscle mass had a greater tendency for depressed mood compared to girls with optimal muscle mass (P = 0.023). After adjusting for age, waist circumference-to-height ratio, smoking status, alcohol consumption, frequency of physical activity, self-reported obesity, weight-loss efforts, and monthly household income, girls with low muscle mass (LMM) were 2.60 times more at risk of developing depression than girls with normal muscle mass (95% confidence interval [CI], 1.05-6.49; P = 0.040). This trend was similar for girls with LMM with obesity (95% CI, 1.00-11.97; P = 0.049). Conclusion: Adolescent girls who have insufficient muscle mass are more likely to report depressed mood than girls who have ideal muscle mass. Interventions for maintaining proper muscle mass are required.

Purpose: This study explored the experiences of pregnant women with depressed mood participating in a group cognitive behavioral therapy (CBT) program using video communication, based on Beck's cognitive theory. Methods: The participants were six pregnant women out of 13 women who had participated in an 8-session group CBT program using video communication for women with depressed mood (Edinburgh Postnatal Depression score of ≥9). Data were collected from February 20 through March 25, 2021. In-depth individual interviews were conducted through a video conferencing platform at 1 month post-baseline. Thematic analysis was done. Results: Three themes, 10 subthemes, and 38 concepts were derived from experiences of participating in the 4-week group CBT program (twice a week). The first theme, entitled "continuing realization" had subthemes of "a negative and instable self," "a selfish judgment that excludes others," and "a strong belief in self-control." The second theme, entitled "attempt to change for restoration" had subthemes of "shift to rational thinking," "freedom from suppressed beliefs," "tolerance of other people," and "courage for self-expression." The third theme, entitled "departure for a positive life," had subthemes of "emotional healing," "faith in oneself," and "reestablishing the criteria for happiness." Conclusion: Pregnant women with depressed mood expressed that continuing realizations and attempts to change supported their transition toward a positive direction of healing. Thus, they were able to change their distorted thinking into rational thinking through CBT using video communication. These findings support the use of group CBT using video communication with pregnant women who have depressed mood.

Subjects were 134 institutionalized children(86 boys, 48 girls) and 218 non-institutionalized children(115 boys, 103 girls). Findings were that (1) institutionalized children showed lower internal locus of control than non-institutionalized children. (2) Institutionalized children with internal locus of control showed active coping behavior. Non-institutionalized children with internal locus of control showed active and social support seeking coping behavior, and non-institutional children with external locus of control showed aggressive coping behavior. (3) Regression analysis models showed that institutionalized girls were more depressed than boys; depressed institutionalized children were oriented to external locus of control and passive coping behavior. Depressed non-institutionalized children were oriented to external locus of control and passive, evasive coping behavior and showed lower active and social support seeking behavior.
