To apply the serum xanthine oxidase (XO) determining for the index of the toluene intoxication, the serum XO activity was compared with the other parameters, the activities of serum alanine aminotransferase(ALT), aspartate aminotransferase(AST), 5'-nucleotidase(5'-NT), alkaline phosphatase(ALP), guanase(GDA) and $\gamma$-gIutamyl transpeptidase(T-GTP). Concomitantly, the cause of increased level of serum XO was clarified in the present experimental conditions. Although the other serum enzyme activities, ALT, AST, 5'-NT, ALP, GDA and $\gamma$-GTP were respectively not found to be different between control group and toluene-treated group, the serum XO activity in toluene-treated group showed the higher levels than that in the control group. These suggested that the determination of serum XO activity could be used for monitoring the intoxication of toluene. On the other hand, the activities of XO both in the serum and liver were higher in toluene-treated or benzaldehyde-treated rats than those in each control group. In the pooled liver XO from each group, toluene-treated or benzaldehyde-treated group showed the higher $V_{max}$ value than the control group, whereas no changes were observed in liver XO activities between the control liver specimen and that preincubated with bertzaldehyde in vitro. The present results indicate that the increased level of XO in toluene-treated rats is due to the result of enzyme protein induction in liver cell by the benzaldehyde metabolized from toluene. All the more, the benzaldehyde may be acted as a substrate for XO, since the benzaldehyde induced the increased activity of both liver and serum XO, and no changes were found in purine catabolite, uric acid in serum or urine and liver purine catabolizing enzymes, adenosine deaminase, GDA, uricuse except XO in toluene-treated rats.

Hyaluronic acid (HA) is an almost essential component of extracellular matrices. Early in embryogenesis mesenchymal cells migrate, proliferate and differentiate, in part, because of the influence of HA. Since the features of embryogenesis are revisited during wound repair, including bone fracture repair, this study was initiated to evaluate whether HA has an effect on calcification and bone formation in an in vitro system of osteogenesis. Mouse calvaria Pre-osteoblast (MC3T3-E1) cells were cultured in ${\alpha}-MEM$ medium with microorganism-derivative hyaluronic acid that was produced by Strep. zooepidemicus which of molecular weight was 3 million units. The dosages were categorized in each 0.5, 1.0 and 2.0 mg/ml concentration experimental groups. After 2 and 4 days cultures in expeirmental and control groups, the tendency of cell proliferation, MTT assay, protein synthesis ability, collagen synthesis and alkaline phosphatase activity were analysed and bone nodule formation capacity were measured with Alizarin Red S stain after 29 days cultures. The cell proliferation was increased in time, especially the group of 0.5 and 1.0 mg/ml concentration of HA were showed prominent cell proliferation. After 2 and 4 days culture, experimental groups in general were greater cell activity in MTT assay. The protein synthesis was increased in all experimental groups compared to control group, especially most prominent in 1.0 mg/ml concentration group. The collagen synthesis capacity were increased in HA experimental groups, especially prominent in 1.0 mg/ml group and the activity of alkaline phosphatase were increased, especially also prominent in 1.0 mg/ml group, compared to control group. Above these, the activity of mouse carvarial pre-osteoblast cells was showed greater bone osteogenesis activity in all applied HA experimental group, especially group of 1.0 mg/ml concentration of HA.

In order to investigate the effect of autoxidized oil on the enzyme activity in the mouse liver, we administered the fixed dosage of autoxidized methyl linoleate (AOML) to mice once per day for 20 days by using stomach tube and investigated the enzyme activity with the histochemical staining method and biochemical analysis. The following results were obtained: The POV, COV and TBA value in the liver of AOML group were significantly increased than those of normal group. The phospholipid, triglyceride and total cholesterol in the liver of AOML group were slightly increased than those of normal group. The activities of acid phosphatase and alkaline phosphatase in the liver of AOML group were increased than those of normal group but ATPase activity was decreased in the AOML group. The decrease of RNA, accumulation of fat and damage of liver cells were observed as the morphological changes in the liver of AOML group. From the results obtained we conclude that the autoxidized methyl linoleate influenced upon the various enzyme activity and the morphological changes in the mouse liver.

Purpose : This study aimed to investigate the effect of trunk postural stability maintained wearing a spiral elastic band on the upper extremity function of patients with stroke who undertook a functional activity program and to provide fundamental data useful for the application of therapeutic interventions in the clinical environment of occupational therapy. Methods : The research subjects included 16 patients with stroke who were evenly divided into an experimental group and a control group. The eight-week intervention consisted of a functional activity program aimed at improving the function of the affected-side upper extremity. The experimental group performed the functional activity program while maintaining a stable trunk posture by wearing a spiral elastic band. The control group followed the program without wearing the band. Upper extremity function was assessed before and after the intervention using a manual function test (MFT) and a motor activity log (MAL), and the effectiveness on the upper extremity function of the affected side was confirmed. Results : First, in the within-group comparison of the upper extremity function scores before and after the intervention, the experimental group showed a statistically significant difference in the MFT and MAL assessment(p<.05). The control group showed a statistically significant difference in the MAL assessment(p<.05). Second, in the between-group comparison of the change in scores after the intervention, a statistically significant difference was observed between the two groups in all assessments(p<.05). Conclusion : This study confirmed the positive effect on upper extremity function of trunk stabilization posture using a spiral elastic band. The results could be useful when implementing a task-oriented training program in the clinical environment of occupational therapy in the future, as application of the training while maintaining trunk postural stability by wearing a spiral elastic band could be more effective for improving the upper extremity function of patients with stroke.
Purpose: The purpose of this study was to compare the metabolic syndrome (MS) risk factors, physical activity, and diet habits, between the fifties and sixties in postmenopausal women. Methods: Two hundred and thirty subjects were recruited from the volunteers of a tertiary care hospital located in an urban city of South Korea. MS was defined by the criteria of the American Heart Association, the National Heart, Lung, and Blood Institute, and the International Diabetes Federation, and obesity was determined by waist circumference ${\geq}85cm$. Results: During fifty and sixty years of age, the prevalence of MS was 19.7% and 30.6%, respectively. The waist circumference, triglyceride, blood pressure, and fasting serum glucose levels were significantly higher in the MS group than in the non-MS group during their fifties and sixties. For participants in their sixties, the pulse pressure and fasting serum glucose levels were significantly higher in the MS group than in the non-MS group. Physical activity was significantly lower in the MS group than in the non-MS group in their sixties. Conclusion: These results show that nurses should focus on increased physical activity for patients their sixties, especially MS patients for the improvement of MS risk factors.

The purpose of this study is to provide fundamental clinical data for the treatment plan and rehabilitation of patients with cervical hypolordosis by comparing the cervical headache and muscle activity after cervical stretching exercise and cervical traction, which are generally applied to patients with cervical hypolordosis. The research subjects included 20 patients without gender division who were diagnosed with cervical hypolordosis. After applying cervical stretching exercise and cervical traction for six weeks, cervical headache and the activity of the muscles around the cervical vertebra(upper trapezius muscle, sternocleidomastoid muscle, splenius capitis muscle, and anterior temporal muscle) were investigated and the following results were obtained. In a comparison of the within group intervention effects of the two groups, cervical pain statistically significantly decreased in the cervical stretching exercise group. According to the results of analyzing the change of muscle tension in the upper trapezius muscle, both the cervical traction group and showed a statistically significant within group difference in the left and right side. According to the results of analyzing the change in the muscle tension of the splenius capitis muscle, both groups showed a statistically significant within group difference in the left and right side. In a between-group comparison, a statistically significant difference in the right side was observed. These results confirm that cervical vertebra traction and cervical stretching exercise decrease the cervical headache and muscle activity of the upper trapezius muscle and the splenius capitis muscle among patients with cervical hypolordosis.
The antioxidant activity and quality characteristics of bread made from waxy black rice flour(WBRF) and green tea powder were investigated. The bread was manufactured with 1% of green tea powder and 10, 20, 30 or 40% of WBRF(w/w). The group of 40% of WBRF and green tea powder significantly showed the highest bread weight and volume. Lightness(L value) and yellowness(b value) decreased, but redness(a value) increased with increasing WBRF contents in mixture. Hardness, gumminess and chewiness were the lowest in the control group, but springiness was the lowest in the group of 40% of WBRF and 1% of green tea powder. The sensory scores of appearance, external and crumb color, grainy in the group of 40% of WBRF and 1% of green tea powder were the significantly lowest. Overall acceptabilities of the groups of 10% and 30% of WBRF with 1% of green tea powder were not significantly different from the control group. The group of 40% of WBRF and 1% of green tea powder showed the highest DPPH radical scavenging effect and TEAC content. Thus, if the mixture of green tea powder and WBRF would be used, it might be proper to use 1% of green tea powder and 10% of WBRF mixture considering the quality and antioxidant activity of bread.
Purpose: This paper proposes proper and effective neck exercises by comparing the deep and superficial cervical flexor muscle activities and thickness according to the pressure level during cranio-cervical flexion exercises between a normal posture group and forward head posture group. Methods: A total of 20 subjects (8 males and 12 females) without neck pain and disabilities were selected. The subjects' craniovertebral angles were measured; they were divided into a normal posture and a forward head posture group. During cranio-cervical flexion exercises, the thickness of the deep cervical flexor neck muscle and the activity of the surface neck muscles were measured using ultrasound and EMG. Results: The results showed that the thickening of the deep cervical flexor was increased significantly to 28 and 30 mmHg in the forward head posture group. The sternocleidomastoid muscle activity increased significantly to 24, 26, 28, and 30 mmHg in the forward head posture group. The anterior scalene muscle activity increased significantly to 26, 28, and 30mmHg in the forward head posture group. A significant difference of 26, 28, and 30 mmHg in the sternocleidomastoid and anterior scalene muscles was observed between two groups. Conclusion: To prevent a forward head posture and maintain proper cervical curve alignment, the use of the superficial cervical flexor muscles must be minimized. In addition, to perform a cranio-cervical flexion exercises to effectively activate the deep cervical flexor muscles, 28 and 30 mmHg for normal posture adults and 28 mmHg for adults with forward head postures are recommended.
Background: The purpose of this study was to find out how the lumbar instability during clam exercise causes changes in pelvic rotation and hip joint abductor muscle activity. Design: Case-control study. Methods: Twenty male participated in this study. The amount of pelvic rotation was measured using myomotion during the clam exercise in a normal group and a group of patients with low lumbar instability, and the muscle activity of the muscle gluteus medius and the tensor fasciae latae using an EMG device. Results: The amount of pelvic rotation that occurred during the clam exercise was statistically significantly greater in the lumbar instability group than in the normal group (p<.05), and the ratio of muscle activity of the muscle gluteus medius/the tensor fasciae latae was statistically significantly higher in the normal group than in the lumbar instability group (p<.05). Conclusion: In order to stabilize the lumbo-pelvic and strengthen the strength of the hip joints, it is believed that it is necessary to apply exercise while controlling the lumbo-pelvic movement during clam exercises, and various studies will be needed.
