This study was undertaken to investigate the effect of dietary Fe levels on Cd accumulation in Cd poisoned rats. Forty male weaning Sprague Dawley rats weighing 80-90g were divided into 4 groups(LFe : low Fe, LFeCd : low Fe and Cd, AFe : adequate Fe, AFeCd : adequate Fe and Cd) according to Cd administration(Cd : 0 or 50ppm in drinking water) and Fe levels (Fe : 6 or 40ppm in diet) for 12 weeks. The food intake and weight gain of LFe and LFeCd were significantly lower than those of AFe and AFeCd(p<0.01, p<0.001). The water intake was not affected significantly by Cd and Fe, therefore Cd intake was no significant difference between groups. The Cd accumulation of kidney in LFeCd was significantly higher than those of AFeCd(p<0.001). But the Cd accumulations of brain, liver and spleen were not significantly different between Cd groups and without Cd groups. The serum Cd content and urinary Cd excretion of LFeCd was significantly higher than those of AFeCd(p<0.01, p<0.01). But the fecal Cd excretion of LFeCd was significantly lower than that of AFeCd(p<0.001). The Cd retention, Cd retention rate, and apparent Cd digestibility of LFeCd were significantly higher than those of AFeCd(p<0.001, p<0.001, p<0.001). It was concluded that adequate Fe supplementation have protective effects on the long term Cd poisoning in rats.

Echocardiography is one of the most useful diagnostic techniques for differentiating heart disease as well as mitral valve lesion. Forty client-owned small breed dogs (weight, 2.3-13.2 kg) aged between 8-17 years with myxomatous mitral valve degeneration (MMVD) were included in the present study. The diagnosis of MMVD in dogs was made based on the clinical signs, chest radiography data, and echocardiographic findings. Echocardiographic examinations were conducted in accordance with recommended standards for dogs. M-mode, Doppler, and 2D echocardiography were performed in left and right lateral recumbency. 2D echocardiography was used to measure LA and Ao diameter from 2D short axis at the level of the aortic valve. In the comparison of conventional echocardiography indices in dogs with different stages of heart failure with MMVD, significant differences were observed in E/A ratio (p=0.005), EDV (p<0.001), EDVI (p<0.001), E-peak velocity (p= 0.001), ESV (p=0.028), ESVI (p=0.004), LA (p<0.001), LA/Ao Ratio (p<0.001), LVIDd (p<0.001), LVIDd/Ao Ratio (p<0.001), LVIDs (p=0.036), LVIDs/Ao Ratio (p=0.002), and MR Velocity (p=0.026). In addition, distinct correlations were found in EDV (r=0.712), LA/Ao ration (r=0.830), LVIDd (r=0.724), and LVIDd/Ao ratio (r=0.759). This study found that known conventional echocardiographic indices, including EDV, LA/Ao ratio, LVIDd dimension, and LVIDd/Ao ratio correlated with the severity of MMVD in point of significant differences and distinct correlations.

The aim of this study was to effect of muscle activity on muscle architectural of medial gastrocnemius in chronic stroke patient based on ankle joint degree. The subjects of this study were 10 chronic stroke patients modified Ashworth scale(MAS) 2. Ultrasonographic and dynamometer was measured during resting and maximum voluntary isometric contraction(MVIC) on muscle thickness, pennation angle, fascicle length, MVIC. Result from analysis showed that muscle thickness was thinner in the paretic side than in the non-paretic side(p<.001) and the more plantarflexion increased, the thinner muscle thickness became. And at the time of resting rather than of MVIC significant(p<.001). Result from analysis showed that penneation angle was smaller in the paretic side than in the non-paretic side(p<.001) and the more plantarflexion increased, the larger pennation became. And at the time of resting rather than of MVIC significant(p<.001). Result from analysis showed that fascicle was shorter in the paretic side than in the non-paretic side(p<.001) and the more plantarflexion increased, the shorter fascicle length became. And at the time of resting rather than of MVIC significant(p<.001). The results of this study showed that effect of muscle activity on muscle architectural of medial gastrocnemius in chronic stroke patient based on ankle joint degree. Therefore, Ultrasonographic evaluation of chronic stroke patients according ankle joint degree and muscle activity in the clinical diagnosis and therapy is considered a very useful data.

The purpose of this study was to examine the impact of the oral health behavior and self-rated oral health of workers on their happiness indexes in an attempt to provide information on oral health planning geared toward industrial workers. The subjects in this study were 294 workers in North Gyeongsang Province. As a result of analyzing the relationship between their health behavior and happiness indexes, the workers who got regular health checkups had higher happiness indexes for both single items(p=0.002) and entire five items(0.012), and those who had their teeth cleaned over the past year had higher happiness indexes for both single items(p<0.001) and entire five items(p=0.003). As for a toothbrushing frequency, the respondents who brushed their teeth more frequently had higher happiness indexes for both single items(p<0.001) and entire five items(p=0.023), and those who had ever received oral health education had higher happiness indexes for both single items(p=0.041) and entire five items. The workers who kept their toothbrushes at work had higher happiness indexes for both single items(p=0.001) and entire five items, and the respondents who could afford to visit a dental clinic immediately in case of having a toothache had higher happiness indexes for both single items(p<0.001) and entire five items(p<0.001). The findings of the study suggest that the preparation of systematic oral health programs is required to boost the happiness indexes of industrial workers.
