An animal which is placed in a new environment displays a complex behavioral pattern consisting of locomotion, grooming and rearing. This behavioral pattern is influenced by endogenous and exogenous stimuli, such as hormonal secretion, level of neurohumoral transmitters, drugs and light. It is widely known that the most tranquilizers depressed spontaneous motor activity although their mechanisms of action were different, while antidepressants stimulated except imipramine which showed various action. Until the present time, the hole-board apparatus, which gives rather subjective data, has been used extensively to study the effects of drugs on general activity and exploratory behavior in mice. Recently a new apparatus for mobility measurements, called a 'Selective Activity Meter' has been introduced. This instrument supposedly produces more objective data on activity and behavior. The purpose of the present experiment was to study the influence of psychotropics on motor activity using the Selective Activity Meter. In the experiment, various psychotropic agents such as major tranquilizers(chlorpromazine, haloperidol); minor tranquilizers(meprobamate, diazepam); and antidepressants(amphetamine, imipramine) were used. In each experiment, the drug was administered to five mice and their activity was recorded. Each experiment was run five or more times and the results are based on the mean of each trial. The results are summarized as follows: 1. The group of mice treated with chlorpromazine showed markedly inhibited motor activity in comparison with controls and the inhibitory action of chlorpromazine was shown to be more intense than any of the other drugs used in the test. Haloperidol administration yielded similar results until 60 minutes, but mice showed less inhibition of motor activity than with chlorpromazine after 90 minutes. 2. In the group treated with diazepam, there was strong inhibition of motor activity until 30 minutes, but after 60 minutes the mice showed less inhibition than with chlorpromazine. In the meprobamate group, motor activity was inhibited in a manner similar to that of other tranquilizers, but the inhibition was less than that of diazepam. 3. In the group treated with imipramine, the inhibition developed gradually after ten minutes. 4. The effects of amphetamine did not appear until 30 minutes after administration, but then there was a significant increase in the motor activity.

Purpose : The number of young patients with diabetes is on the rise, and they face challenges in managing their blood sugar levels. This study aimed to investigate the effect of physical activity on blood sugar control in young and middle-aged patients with diabetes aged 19-64 years using data from the 8th Korea National Health and Nutrition Examination Survey (2019-2021). Methods : Blood sugar control in patients with diabetes was determined based on FBG 110 mg/㎗, and physical activity was measured using physical activity categories that considered the sum of walking, moderate intensity, and high intensity. Statistical analysis was conducted using SAS 9.4, and the Rao-Scott chi-square test was conducted to determine differences in blood sugar control based on the sociodemographic characteristics and physical activity of patients with diabetes. Complex-sample multiple logistic regression analysis was conducted to assess the effect of physical activity on blood sugar control. Results : There were statistically significant differences in blood sugar control between young and middle-aged patients with diabetes, depending on sex, age, marital status, obesity, and amount of physical activity. As a result of the complex sample simple logistic regression analysis without adjusting for variables, the non-physical activity group was found to have a higher risk of blood sugar dysregulation than the health-promoting physical activity group (OR: 2.80). Complex-sample multiple logistic regression analysis with control variables showed that the non-physical activity group had a higher risk of blood sugar dysregulation than the health-promoting physical activity group (OR: 3.70). Conclusion : Multifaceted efforts are needed to develop health intervention programs that can increase physical activity, diabetes awareness, and treatment rates, including controlling blood sugar levels and preventing complications in young and middle-aged patients with diabetes.
Objectives : The purpose of this study was to observe the anti-oxidative effects of electroacupuncture at Pungyung($ST_{40}$) in rats.

Results : 1. Liver index was decreased in the $ST_{40}-EA$ group compared with the holder group and the control group. 2. LDL-cholesterol was significantly decreased in the $ST_{40}-EA$ group compared with the group. 3. SOD activity was significantly increased in the $ST_{40}-EA$ group and $ST_{40}-NR$ group compared with the control group. Glutathione activity was significantly increased in the $ST_{40}-EA$ group compared with the control group, the holder group, and the Sham-EA group. Catalase activity was significantly increased in the $ST_{40}-EA$ group compared with the control group and the holder group. Conclusions : These results suggest that electroacupuncture at $ST_{40}$ has an antioxidant effect in rats.
Purpose: In this study rest-activity rhythm, sleep pattern and quality of life of patients with restless legs syndrome were compared with those of a normal group. Methods: The participants in this study were 36 patients with restless legs syndrome diagnosed by a neurologist and 36 participants in the normal group. An actigraph, sleep diary, Pittsburgh Sleep Quality Index and Insomnia Severity Index scale were used as measurement tools for the study. Chi-square test, Lamda test, t-test and Kendall's correlation with SPSS 12.0 program were used to analyze the data. Results: Patients with restless legs syndrome had a higher rest-activity rhythm curve of Least 5 hr's activity(L5) and Most 10 hr's activity(M10) than those of normal group and sleep problems included decreased sleep efficiency and increased sleep latency, wake time and number of awakenings. The scores for the subscales of quality of life in patients with restless legs syndrome were lower than the normal group for general health, physical functioning, role limitations due to emotional problems, role limitation due to physical problems, social functioning, bodily pain, vitality and mental health. Conclusion: The results suggest that further studies are needed to identify rest-activity rhythm according to symptom severity and to develop nursing interventions which consider rest-activity rhythm.

501 preschool children from 4 to 6 years were examined for their salivary reductase activity and caries experience by Resazurin Disc Test and dental examination respectively. We asked the parents about their children's oral hygiene habits, between-meal eating habits, and physical exercise habits by the questionnaire. Toothbrushing frequency had negative relation to salivary reductase activity and caries experience. Caries experience was low when parents did toothbrushing for children, when teeth were brushed at bedtime, and when fluoride toothpastes were used. Salivary reductase activity and caries experience were high in bread & cookies group, chocolates & candies group, milk & soft drink group, and fruits & vegetables group in order. Caries experience was high in case of irregular between-meal eating. Sweet food eating frequency had positive relation to caries experience. Caries activity was low in case of eating homemade non-sweet between-meals. Salivary reductase activity and caries experience were low when gum-chewing frequency was high. Salivary reductase activity and caries experience were high when the amount of physical exercise was low.

This study was performed to evaluate the effect of iron supplementation on iron-deficiency-related indices, oxidative stress and antioxidative enzyme activity in female marathoners. Fourteen teenage female marathoners participated in the study. Subjects were divided into two groups: mild anemic and control, depending on their hemoglobin (Hb) level. The mild anemic group had significantly lower RBC count and hematocrit (Hct) and Hb levels compared to the control group. The mild anemic group (〈12.5g Hb/dI, n=7) was given iron supplements (60mg Fe/day) for four weeks during the summer training period. RBC count, Hct and Hb levels showed an increasing tendency through iron supplementation, and significant differences in these variables between the anemic and control groups disappeared in the post-period. There was no difference in plasma malondialdehyde (MDA) between the anemic and control groups. However, catalase (CAT) and glutathione peroxidase (GPx) activity were significantly higher in the anemic group. The significant difference in enzyme activity between the groups disappeared in the post-period. In addition, superoxide dismutase activity significantly decreased after iron supplementation. In conclusion, antioxidative enzyme activity was up-regulated in an anemic condition and mild iron supplementation decreased the antioxidant enzyme activity of female marathoners while improving their anemic condition.
Purpose: The purpose of this study was to investigate the effect of a kettlebell complex program according to the support surface on the lower extremity muscle activity and balance of baseball players. Methods: The participants were divided into two groups; unstable support surface group 1 (11 people) performed the kettlebell complex program on an unstable support surface, and stable support surface group 2 (10 people) performed the kettlebell complex program on a stable support surface. Muscle activity was measured by surface electromyography. Dynamic balance was measured with a balance-measuring equipment. A paired t-test was used to compare groups before and after the experiment. An independent t-test was performed to determine the difference in the degree of change between the two groups before and after the experiment. Results: The intragroup comparison between stable support surface group 1 and 2 showed significant differences in muscle activity and sense of balance. In the comparison between the groups, the difference in muscle activity in unstable support surface group1 was significant in the biceps femoris and rectus femoris muscles, and significant differences were also found in the sense of balance. Conclusion: These results suggest that a kettlebell exercise on an unstable support surface is more effective in improving muscle activity and sense of balance than a kettlebell exercise on a stable support surface.
This study aimed at examining an effect of peer counselor's mentor activity on rejected children's peer relationship in elementary school. To achieve this goal, the following hypothesis was made. Hypothesis I : Peer counselor's mentor activity will improve rejected children's peer relationship. I -1 : Peer counselor's mentor activity will improve rejected children's trust to peer. I -2 : Peer counselor's mentor activity will improve rejected children's respect to peer. To test the hypothesis, after sociometry papers 19 fifth-graders for rejected children groups were selected from four classes at H elementary school in Busan according to Coie & Dodge's(1988) five classified system that is modified to Korean situation by Ahn ie-hwan(2006). Ten rejected students from two classes were labeled as a peer group with a peer counselor and nine rejected students who had similar characteristics from two classes were labeled as an non-peer group without a peer counselor. The peer counselors were decided by obtaining affirmative mentions of rejected students group. Peer counselors participated in the training of peer counselor's skill program and then they had a person to person mentor activity with the rejected children's group that they belonging to. The training consisting of a total of four sessions, 3 times a week, was provided to peer counselors eleven times after school. The peer counselors given the peer counselling training did person to person mentor activity with the peer group's rejected children for a month. The mentor activity, three times a week, following during training was reinforced after school. For peer counselor training, the elementary school children's peer counseling program developed by Lee Sang-hi, Roh Seong-deok and Lee Ji-eun(2001) was used. Hong Ok-soon's(1984) peer relationship test, Moreno's(1934) sociometry tool were used to verify an effect of the peer counselor's mentor activity. For the data analysis, quantitative analysis with sociometry tool and qualitative analysis with social status and social type change were used. To know the difference in pre test and post test peer relationship between experimental group and control group, in quantitative analysis, ANCOVA result was used and qualitative analysis, social status and social type was used. The finding was as followings. First, after peer counselor's mentor activity, there was a significant improvement in rejected children's trust and respect to peer and the whole relationship from the pretest to the post test. Second, peer counselor's mentor activity gave rise to affirmative changes on rejected children's social status and social type. This study concluded that peer counselor's mentor activity would help rejected children's peer relationship to change affirmatively and improve.
The effects of brisk walking & muscle strengthening exercise on pain, fatigue, physical function & disease activity were examined in 28 patients with rheumatoid arthritis. Research design was a quasi-experimental study of non-equivalent control group pretest-posttest design. 14 for the experimental group and 14 for the control group were selected from the out patients on rheumatoid arthritis clinic of Dong-A University Hospital. The experimental group underwent 16 weeks of brisk walking and muscle strengthening exercise using Thera-Band. Pain, fatigue, physical function & disease activity was measured before and after 16 weeks of exercise. At baseline test, Fatigue & physical function score between groups were significantly different. So differences with in experimental group(baseline versus follow up) were compared with differences within the control group by Mann-Whitney test. There were significant differences between groups in the difference score on pain (U=6.50 p<.001) and fatigue (U=26.5 p<.01). For the experimental group, the score on the pain & fatigue was significantly decreased but no changed for the control group. Also there was a significant differences between groups in the difference score of the physical function (U=22.5 p<.001). For the experimental group, the score of the physical function has been significantly in creased. However, for the control group, it has been no changed. But there were no significant differences between groups in the ESR (erythrocyte sedimentation rate) and the CRP (C-reactive protein)level. In summary, brisk walking & muscle strengthening exercise led to significant improvements in pain, fatigue, and physical function without exacerbating disease activity in patients with rheumatoid arthritis.
This study was performed to investigate the modifying effect of the general (GPA) and the fermented pilose antler (FPA) on experimental hepatocarcinogenesis and Natural Killer cell activity in rats. Specific pathogen free, 5-week male Sprague-Dawley rats were divided into four groups. To induce hepatocarcinogenesis, diethylnitrosamine (DEN, 200 mg/kg, i.p.) was used as a tumor initiator and was given in a single dose at experimental onset. All rats were given a partial hepatectomy (PH) at 3 weeks after experimental onset. Sodium phenobarbital (PB, 0.05% in diet), GPA (0.075% in diet) and FPA (0. 075% in diet) were given from 2 to 8 weeks. Group I of the initiation control group was only given DEN. As initiation-promotion group, Group II was given DEN and then PB. Group III and IV were given DEN-PB-GPA and DEN-PB-FPA, respectively. In hematological analysis, as compared with Group I. the number of white blood cells were significantly increased in the GPA (p<0.01) and the FPA treated group (p<0.05), respectively. Natural killer (NK) cell activity by flow cytometer (FCM) analysis was higher in group of treated with the GPA (35%) than that of the FPA (27.5%), but not significant. Result of the immunohistochemical staining of the glutathione S-transferase placental form (GST-p) indicated that the number of and area of the pre-neoplastic lesions was not significantly changed in Group III and IV compared Group II, respectively. In conclusion, the GPA and the FPA treatment significantly increased the number od WBC in peripheral blood, but the enhancing NK activity and the modifying effect on the experimental hepatocarcinogenesis were not observed.
