This study was carried out to investigate the optimum rate of substrate composition in bottle cultivation of Grifola frondosa and had three rates of substrate composition of 67:11:22(T1), 68:15:17(T2) and 74:14:12(T3) as mixing rate of weight of dried oak sawdust, dried corn husk and dried bean-curd refuse. The rate of primordia formation of T3 was 65.8% which was lowest among all treatments. Contraction rate of disease of T1 was 9.8% which was highest among all treatments. Harvesting rate of T2 was 70.5% which was highest among all treatments. Fruit body weights per bottle of T1 and T2 were 85.5 g, 83.3 g respectively and there was not significant difference between those. Yield per 10,000 bottles of T2 was 587 kg and was 7%, 28% higher than those of T1 and T3, respectively. As a result, the rate of substrate composition of 68:15:17(T2) as mixing rate of weight of dried oak sawdust, dried corn husk and dried bean-curd refuse was appeared as optimum rate of substrate composition in bottle cultivation of Grifola frondosa..

This study investigated the effect of belly fat on the plasma lipid concentrations in rats. The results were obtained from the rats that had been fed the experimental purified diets containing 5％ corn oil (C) as the control, 5％ commercial lard (Tl), 5％ belly fat (T2), 10％ belly fat(T3), and those given diet(T4) by feeding either C or T3 alternately every 3 days for 30 days. The food intake and food efficiency were not show any significant difference among the treatments. The body weight gain tended to significantly increased when the feeding of added-belly fat in diets (p＜0.05). The plasma triacylglycerides of T3 was higher than the other treatments, and significantly elevated as the number of feeding days of the diets with the belly fat passed when compared to diet C (p＜0.05). The plasma total cholesterol of T3 showed the highest levels in the treatment groups, and was high in the order of T1, T2, T4, and there was a significant difference between the rats given the diet with belly fat and C (p＜0.05). The plasma HDL-C of T2 and T3 was showed the lowest levels in the treatment groups. The plasma HDL-C of T1, T2, T3 and T4 groups were significantly decreased as the number of feeding days of the diets with the belly fat increased when compared to diet C (p＜0.05). The plasma LDL-C and Al of T3 showed the highest levels in the treatment groups, and the levels were in order of T1, T2, T4. There was a significant difference between the groups of rats given the belly fat and C (p＜0.05). The bleeding times significantly decreased as the number of feeding days of the belly fat diets increased, and T3 showed the lowest levels, there was a significant difference among the treatment groups (p＜0.05). The whole blood clotting times of T3 showed the lowest values, and significantly decreased according to the number of days of the rats were fed the belly fat diet (p＜0.05). These results showed that frequent consumption and high intake of pork belly can elevate the plasma triacylglyceride and cholesterol levels, and also accelerate red thrombus formation because belly fat contains high levels of saturated fatty acids and cholesterol.

This study was carried out to investigate the effects of dandelion leaf, root and whole part extracts on the physicochemical characteristics of pork patties stored at $4^{\circ}C$ for 10 days. Four types of pork patties were evaluated: ice-water-added (T0), dandelion leaf extract (T1), dandelion root extract (T2) and dandelion whole part extract (T3). The pH decreased significantly during storage, but increased after 10 days of storage. The pH was highest in T0 during storage. The L value of T0 increased whereas T1, T2 and T3 did not significantly changed during storage. The a value decreased with a longer storage period, and the a values for T1, T2 and T3 were higher than that of T0 during storage. The b value did not change significantly during storage. The TBARS increased with a longer storage period, and the values for T0, T1, T2 and T3 were 0.87, 0.29, 0.47 and 0.31 mg MA/kg, respectively, after 10 days of storage. The VBN content value of T0 increased, but those of T1, T2 and T3 did not significantly change during storage. The water holding capacity of T0 decreased, but those of T1, T2 and T3 did not significantly change during storage. Cooking loss increased during storage and that of T0 was higher than those of T1, T2 and T3. Hardness and chewiness decreased while springiness and cohesiveness increased during storage.

The 36km-long Daebo-Campo coast has a well-developed marine terraces divided to six steps by elevation of paleoshoreline : 0.5 m(T1), 10 m(T2), 30 m(T3), 40 m(T4), 60 m(T5) and 75 m(T6). The 2$^{nd}$ and 3$^{nd}$ platforms in Daebo to Guryongpo are wider and more distinctive than those of Guryongpo to Gampo. The 3$^{nd}$ terrace of 30 m high is subdivided to two flights as lower(T3b) and upper(T3a) by old sea cliff. Platform age is unclear because of coral fossil free. However, the terrace age could be determined with convergent OSL ages from beach sediments on 2$^{nd}$ step(T2). OSL ages of the terrace of 10 m high range in 60-70 ka. It reveals that the 2$^{nd}$ -step platform correlates to Oxygen Isotope Time scale, substage 5a(ca. 80 ka), and that uplift rate is ca. 0.19 m/ka for 2$^{nd}$ terrace at Daebo-Campo coast. If considering equivalent uplift rate for all terraces since the Late Pleistocene, the 3$^{rd}$ and 4$^{th}$ terraces would be 5e substage and 7 stage. The 30 m-high terrace provides a good indicator for uplift at Daebo-Gampo coast since 125,000 yrs(MIS 5e). It suggests that the local neotectonic deformation might cause an optional uplift rate of ca. 0.19 m/ka along the SE coast of Korea.

This study was performed to elucidate the biochemical mechanism of metabolism on reducing blood lipid, by oral administration of egg yolk in rats. A total of 36 Sprague Dawley male rats were randomized into four treatment groups, according to a randomized block design. Each group was further divided into three repeat cages, with each repeat cage comprising of 3 rats. The animals were orally administered with egg yolk once a day, while feeding the same purified pellet diet for 6 weeks. The four treatment groups were: C(control, saline 1.0 g), T1(pork belly oil 1.0 g), T2(egg yolk 1.0 g), T3(pork belly oil 1.0 g and egg yolk 1.0 g alternating every week). The measured parameters in each group are listed as follows in the order of highest to the lowest: daily average gain of body weight(T1>T3>T2>C); blood triglyceride and total cholesterol(T1>C>T3>T2) HDL-C (T2>C>T3>T1); and LDL-C (T1>T3>C>T2). AST and ALT, which are the index of liver function, were the highest in T1 but was lowest in T2. The weights of the liver, spleen, and kidney, except for the abdominal fat, showed no significant difference. The weight of abdominal fat was the highest in T1, but there were no significant difference among C, T2, and T3. The HMG-CoA reductase activity was the highest in T1 followed by T3, C but T2 was lowest. The daily fecal excretions of the total sterol, neutral sterol and acid sterol was highest in T2 but lowest in T1. The results of this study show that the egg consumption reduces the blood lipid through facilitation of fecal excretions of sterols and inhibition of enzyme activity in cholesterol biosynthesis, in the liver of animal and human.

This study was carried out to investigate the effect of grape peel on the physicochemical properties of ground pork stored at 4℃ for 10 d. Four types of ground pork were evaluated: T0 without grape peel, T1 with 0.3% grape peel, T2 with 0.7% grape peel, and T3 with 1.0% grape peel. The pH increased during storage, with that of T3 the lowest (p<0.05). The L-value and a-value decreased during storage, and the a-values of T2 and T3 were significantly higher than those of T0 and T1 (p<0.05). The b-values of T0 and T1 increased with a longer storage period (p<0.05), but those of T2 and T3 were not significantly changed. The TBARS (2-thiobarbituric acid reactive substances) content increased with a longer storage period, and the TBARS content of both T2 and T3 was significantly lower than that of T0 and T1 (p<0.05). DPPH (1,1-diphenyl-2-picrylhydrazyl) free radical scavenging activity declined with a longer storage period, and the activity of T2 and T3 was significantly higher than that of T0 and T1 (p<0.05). The VBN content of T0 and T1 also increased with a longer storage period (p<0.05), but the VBN content of T2 and T3 was not significantly changed. After storage for 4 d, the water-holding capacity declined and cooking loss and hardness increased (p<0.05), and these parameters were not significantly different among any samples. Chewiness increased with a longer storage period (p<0.05). The results suggest that the addition of grape peel to ground pork can enhance its functionality.

Recently changes in thyroid physiology during acute and chronic medical illness were demonstrated. The serum $fT_3,\;rT_3,\;T_4,\;T_3,\;fT_4$, and TSH concentration were measured by radioimmunoassay method in 49 patients with critical illness and 10 normal subjects to assess the change of thyroid function in critical illness. The results were as follows; 1) The mean serum $fT_3$ concentration was $6.68{\pm}1.05pmol/ml$ in normal subjects while in patients with critical illness the serum $fT_3$ concentration was significantly lowered to $1.55{\pm}1.15pmol/ml$(p<0.001). 2) The mean serum $rT_3$ concentration was $0.22{\pm}0.44ng/ml$ in normal subjects and $0.42{\pm}0.37ng/ml$ in patient with critical illness. There was increment in critically ill patients as compared to normal subjects but no statistically significant difference(p>0.05). 3) The mean serum $T_3$ concentration was $1.24{\pm}0.25ng/ml$ in normal subjects and $0.56{\pm}0.56ng/ml$ in patients with criticial illness and there was significant difference in each other(p<0.005). 4) The mean serum $T_4,\;fT_4$, and TSH concentrations were $7.80{\pm}1.02{\mu}g/dl,\;1.26{\pm}0.39ng/dl,\;1.87{\pm}0.45{\mu}U/ml$ in normal subjects respectively and $6.02{\pm}3.06{\mu}g/dl,\;1.46{\pm}0.80ng/dl,\;1.74{\pm}0.79{\mu}U/ml$ in patients with critical illness and there was no significant difference between critically ill patients and normal subjects. 5) The ratio of mean serum concentration of $fT_3$ and $rT_3(fT_3/rT_3)$, $30.42{\pm}5.58$ in normal subjects was significantly higher(p<0.005) than the coresponding patients with critical illness. 6) The mean serum $fT_3$ concentration in expired cases(n=12) during admission was significant difference between expired and survived cases(p<0.005). The mean serum $rT_3$ centration was $0.67{\pm}0.58ng/ml$ in expired cases and $0.34{\pm}0.22ng/ml$ in survived cases with significant difference(p<0.005). Half of the cases who showed less than $3{\mu}g/dl$ of serum $T_4$ level were expired.

A nitrogen (N) balance trial was conducted to examine the effect of N deprivation on subsequent N retention, blood urea nitrogen (BUN) and IGF-I levels and the ratio of IGF binding protein (IGFBP)-3 to IGFBP-l and -2. Pigs in treatment (T) 1 were given diet A (2.39% N) and those in T2 and T3 were given diet B (1.31% N) and excreta were collected (period 1 (P1)). Pigs in T1 continued to receive diet A while diets for T2 and T3 were changed to diets A and C (2.74% N), respectively. The excreta were collected for two more periods (P2 and P3). During P1, pigs in T2 and T3 retained 50% less N (p<0.001) than those in T1. However, pigs provided T2 (p<0.01) and T3 (p<0.05) retained more N than those assigned to T1 during P2. Pigs in T3 tended to retain more (p=0.10) N than those receiving T2 for the same period. The BUN values were lower (p<0.05) for pigs assigned to T2 and T3 than T1 during P1 and P2. Both IGF-I and IGFBP ratios of pigs assigned to T1 were higher (p<0.05) than those given T2 and T3 during P1 but no differences were found during P2 and P3.

The purpose of this study was to compare the detection rate of brain metastasis according to size of nodule between 1.5T and 3.0T MRI 대상 및 방법： We reviewed 44 patients with primary tumors and clinical symptoms suggesting brain metastasis. After administration of double dose gadolinium-DTPA, MR imaging was performed with 3D SPGR sequence by 3.0T MRI and then with T1 SE sequence by 1.5T MRI. Consequently, comparison was done in 1.5T T1 SE sequence and 3.0T 3D SPGR sequence. With use of the signal intensity (SI) measurements in the metastatic nodules and adjacent tissue, metastatic nodule-to-adjacent tissue SI ratio were calculated. In each patient, the number of metastatic lesions detected in 1.5T and 3.0T, and their size were assessed qualitatively by three blinded readers.
