Histological changes in the thyroid and the liver of broiler chicks and laying hens fed Canadian rapeseed meal(RSM) were observed and following conclusions were made. 1. Grossly, no pathological changes were noticed in the thyroid of broiler chicks and laying hens. In broiler chicks. the liver was slightly paler in color in 12% rapeseed meal fed group. The liver of laying hens fed rapeseed meal for 24 weeks was slightly paler in color both in. 9% and 12% group, and the discoloration was also noticed in 6% group fed for 36 weeks. 2. No histological changes were observed in the thyroid of broiler chicks and laying hens fed rapeseed meal up to 12%. 3. Fatty changes in the liver of broiler chickes fed high level of rapeseed meal were milder in the group substituted for fish meal compared with the group substituted for soybean meal. 4. Fatty liver syndrom of laying hens were more severe in the group fed rapeseed meal for prolonged duration. It should be noted that 12layer were dead due mainly to the liver hemorrhage associated with fatty liver syndrome. It appears that the goitrogenous compound in Canadian rapeseed meal has nearly all eliminated through RSM breeding effort. However, a very little amount of certain compound that disturbs normal fat metabolism in the liver occurs in the rapeseed meal.

Weld overlay is one of the residual stress mitigation method which arrest crack. An overlay weld sued in this manner is termed a preemptive weld overlay(PWOL). PWOL was good for distribution of residual stress of dissimilar metal weld(DMW) by previous research. Because range of overlay welding is wide relatively, residual stress distribution on PWR is affected by welding sequence. In order to examine the effect of welding sequence, PWOL was applied to a specific DMW of KORI nuclear power plant by finite element analysis method. As a result, the welding direction that from nozzle to pipe is better good for residual stress distribution on PWR.

The current study was undertaken to determine the effects of lactic acid bacteria isolated from human intestine on serum and liver cholesterol concentrations and lipoprotein lipase(LPL) activity of adipose tissue in male Sprague-Dawley rats fed high-cholesterol and high-fat diets. The experiment was conducted for 4 weeks with 48 rats(divided into six groups) fed diets containing 0.5% cholesterol and 10% beef tallow except negative control group. The lactic acid bacteria groups(Lactobacillus CYL-5, Streptococcus CYS-8, Bifidobacterium CYB-11 and 3 Strains Mixed) were orally administered with 0.2㎖ lactic acid bacterial culture(10^8-10^9 cfu/㎖) per day. The positive control group received the same diets as the lactic acid bacteria administered groups, but with no lactic acid administration. The regular commercial diet was supplied for the negative control group. Serum total cholesterol and LDL-cholesterol concentrations were significantly(p$lt; 0.05) reduced by administration of Lactobacillus CYL-5 and 3 Strains Mixed. However, there were no significant differences in serum triglyceride and HDL-cholesterol concentrations among the groups. Administering lactic acid bacteria to the rats significantly(p$lt;0.05) also reduced their liver total cholesterol wncentration compared to the positive control rats. Liver triglyceride concentration in Streptococcus CYS-8, Bifidobacterium CYB-11 and 3 Strains Mixed groups were significantly(p$lt; 0.05) lower than that of positive control group. The total lipid concentration in liver was significantly(p$lt; 0.05) lower in 3 Strains Mixed group than in positive control group. LPL activities of epididymal fat pads and mesenteric fat pads in lactic acid bacteria administered groups were lower than that of the control(p $lt; 0.05). LPL activity of mesenteric fat pads were lower than the activity of epididymal fat pads(p$lt;0.05). These results suggest that lactic acid bacteria isolated from human intestine acts as a hypocholesterolemic agent in rats.
