This study investigated the effect of Jerusalem artichoke (Helianthus tuberosus L.) extract on Blood Glucose and Lipid Metabolism in Streptozotocin (70 mg/kg B.W., i.p.)-induced Diabetic Rats. Sprague-Dawley male rats (200~220 g) were divided into normal control group (NC), diabetic control group (DC) and Jerusalem artichoke treated diabetic group (DJ). Diabetes was induced by single intraperitoneal injection of streptozotocin as a dose of 70 mg/kg body weight. Food (p<0.001) and water (p<0.05) intakes were higher in diabetic groups than the normal group. Body weight gain and food efficiency ratio were significantly lower in diabetic groups than normal group (p<0.01). However, they were higher in the DJ group than in the DC group. The serum levels of AST and ALT were significantly lower in the DJ group than in the DC group (p<0.05). The serum level of HDL-C was significantly higher in the DJ group than in the DC group (p<0.001). The serum levels of Triglyceride (p<0.05), LDL-C (p<0.001), and glucose (p<0.001) were significantly lower in the DJ group than in the DC group. At 3 and 4 weeks after the experiment, blood glucose level in the DJ group was significantly lower than the DC group (p<0.05). In conclusion, these results indicated that Jerusalem artichoke can prevent or retard the development of diabetic complications via its beneficial effects for alleviating the hyperglycemia and improved lipid metabolism.

A teratogenic study of dimethyl dimethoxy biphenylate derivative (DDB-S) was carried out on Sprague-Dawley rats. DDB-S dissolved in saline was administered to male and female rats by intravenously injection at daily doses of 50 mg/kg, 75 mg/kg, and 100 mg/kg. A half of dams were sacrificed at 20th day of gestation to scrutinize the pregnant performances and fetal development. And the remaining dams were allowed to deliver. The growth, reflex, behaviour and reproductive function of F1 offsprings were examined. There was no treatment-related difference in body weight, food consumption and necropsy findings of dams. No gross, skeletal and visceral abnormalities was observed in F1 fetuses from dams treated with DDB-S. F1 offsprings did not show any treatment-related difference in growth, reflex, behaviour and reproductive performance. At caesarean section of F1 dams, no growth retardation and gross abnormality was observed in F2 fetuses. In conclusion, DDB-S did not show any potential teratogenic effect in rats.

Changes in nitrite content, TBARS content and color of meat products during storage were examined as part of studies addressing the reduction of residual nitrite and to ensure the safety of meat products. All 4 kinds of domestic meat product tested, Vienna sausage, bacon, smoked-ham and Dduggalbi, manufactured by C and L domestic companies had very low contents of residual nitrite, for below the legal tolerance limit of 70 ppm, and the residual nitrite decreased with storage. The reduction in nitrite content differed with each product, showing the greatest reduction in Vienna sausage and the least reduction in bacon when stored at $4^{\circ}C$. On the other hand, when stored at $-20^{\circ}C$, the nitrite content of bacon decreased more rapidly than the other meat products. The results of this study show that the nitrite content of meat products decreases during storage, and that the rate of decrease is quite dependent on the storage temperature. In addition, the nitrite contents of most domestic meat products are very low compared to the legal limits, thus the health risks of nitrite in meat products might not be of great concern. More research on the reduction of residual nitrite and on the development of alternatives to nitrite is necessary.

The purpose of this study was to suggest a systematic and scientific method for measurement of children's growth development, in which the accuracy of existing diagnosis method has not been concretely examined yet. The most popular method for diagnosis of children's growth is to analyze the opening degree of growth plate in each joint by X-ray image. However, X-ray method has some disadvantages; it is impossible to measure the diagnosis of growth periodically and repeatedly due to the radiation problem. Hence, this study introduced a profile analysis and the algorithm of analyzing the image of growth plate with the BUA(Broadband Ultrasound Attenuation) of calcaneus, to verify the possibility of alternative ultrasonic method harmless to human body. We obtained the images of growth plate in proximal tibiae, phalanges, and calcanei of 269 children (7∼16 years old) with X-ray. And the image of growth plate in calcanei was also obtained front those children with ultrasound. The results showed that the time of the opening degree of growth plate in each joint was almost consistent between X-ray and ultrasonic images. Also, the images of growth plate measured by X-ray and ultrasound showed the high correlation. Therefore, it is expected that the algorithm of ultrasonic profile analysis introduced in this study can replace the existing X-ray method to measure the growth plate correctly.

Objective: The purpose of this study is to conduct a preliminary research for the development of a Performance-Based Cognitive Function Test (PCFT) to screen the elderly for cognitive function impairment, and examine the reliability and validity of the test. Methods: A draft version of the Performance-Based Cognitive Function Test (PCFT) was developed and utilized in nine healthy elderly individuals. In order to verify its reliability, we analyzed the internal consistency of the PCFT. In order to verify the concurrent validity of the PCFT, this study analyzed the correlation between motor-cognitive dual task assessments and the Korean version of the Mini-Mental State Examination (MMSE-K). Results: The internal consistency of the PCFT for motor and cognitive tasks was 0.871 and 0.959 (Cronbach's ${\alpha}$), respectively. Concurrent validity of the PCFT, which was performed through motor-cognitive dual task assessments, ranged from 0.755 to 0.964 (Spearman's rho statistic, p < 0.05). In addition, correlation between the cognitive assessment tool and the MMSE-K ranged from 0.849 to 0.943 (p < 0.01). Conclusion: This study verified, and established the reliability and validity of the PCFT. Further studies are required to examine other psychometric properties in a modified PCFT, for screening cognitive function impairments in the elderly.

We investigated the anti-obesity effect of Gelidium elegans extract (GE) on 3T3-L1 preadipocytes and a high-fat-diet (HFD)-induced mouse model. The results of the present study demonstrated that GE prevents weight gain induced by a high-fat diet (HFD) by modulating the adenosine monophosphate-activated protein kinase (AMPK)-PR domain-containing 16 (PRDM16)-uncoupling protein-1 (UCP-1) pathway in a mice model. Moreover, in vitro results show that GE suppressed adipocyte differentiation by modulating adipogenic regulators, stimulated lipolysis by activating ATGL, and inhibited adipogenesis by downregulating various enzymes associated with triglyceride synthesis. GE was also found to upregulate AMPK phosphorylation as well as the expression of UCP1 and PRDM16 proteins, leading to measurable changes in the beige-like phenotype differentiation of 3T3-L1 cells. Taken together, these findings suggest the role of GE as a functional food ingredient extracted from Gelidium elegans to increase energy expenditure and anti-obesity efficacy.
