This study was designed to investigates the effects of Korean pueraris radix water extract in Cd(cadmium) administered rats. Forty male Sprague-Dawley rats weighing $100{\pm}10g$ were used for this experiment and divided into following 4 groups; control group, 3% pueraria radix in water extract group, 50 ppm Cd group, 50ppm Cd group with 3% pueraria radix in water extract group. The Cd administered rats were given 50 ppm of $CdCl_2\;{\cdot}\;2H_2O$ disolved in the distilled water. The Cd content in the rats tissue of Cd administered group was lower than in the rats tissue of Cd group with 3% pueraria radix in water extract group. Plasma levels of renin activity was increased by Cd administration group, compared with 3% pueraria radix in water extract group and Cd administred group. Glutamate oxaloacetate transaminase(GOT) and Glutamate pyruvate transaminase(GPT) were increased in Cd-administered group and lower in the 3% extracts of pueraria radix in water extract group. Lactate dehydrogenase(LDHase) was lower in the 3% extracts of pueraria radix-Cd group than in the Cd group. This results suggested that pueraria radix in water extract group, has a lowering effects on the accumulation of Cd and it is belived that the pueraria radix in water extract group has some protective effects to Cd administered in rats, but the mechanism of these effects was obscure.

TMR (total mixed ration) feed was developed by adding mugwort (Artemisia capillaris Thunb.) and was fed to Hanwoo cattle. We investigated the effects of feeding mugwort on the physicochemical properties and sensory scores of the Hanwoo beef, as well as the feasibility of producing beef with high quality and function. Samples included Hanwoo loin fed with fattening cattle TMR feed with (treatment) or without mugwort (control). The content of total catechin in Hanwoo loin fed with the treatment and control was 0.516 and 0.307 mg/kg, respectively, while the content of epicatechin was 0.116 and 0.087 mg/kg, respectively, both of which were significant increase from feeding TMR with mugwort (p<0.05). There was no significant difference between the control and treatment in terms of $b^*$ value, VBN content, EDA, total bacterial numbers, freezing loss, thawing loss, cooking loss, hardness, cohesiveness, gumminess, chewiness, shear force, or sensory score of boiled meat. $L^*$, $a^*$ and pH value for the treatment were significantly higher than the control (p<0.05). TBARS and springiness for the control were significantly higher than the treatment (p<0.05). The aroma of the raw meat and the taste, tenderness, juiciness, and palatability of the roasted meat for the treatment were significantly superior to the control (p<0.05). These results suggest that giving feed containing mugwort inhibits lipid oxidation, increases water holding capacity, and improve sensory scores.

Korea paid attention to the work injury insurance in the early economic development stage as other developed countries did. Thus "The industrial Accident Compensation Insurance Law" was legislated in 1963 and it is now expanded to apply to the workplace with five or more employees. Beside the low coverage of the number of employees, the scope of benefits are the problem of work injury insurance. The work injury insurance's main benefits are for the loss of income and the medical cost caused by occupational accidents. On the other hand, the investment on the prevention accident and the medical, social and employment rehabilitation is very low, even though the occupational accident pension is higher than that in other OECD countries. Practically lay-off benefits and survivor' benefit for some special workers are paid more than they need, therefore they want to remain under the benefit condition and the medical care days are longer. This paper indicates the problems of work injury insurance and suggest how to improve the functions of it.

This study was designed to investigate the effect of flower of Pueraria lobata on liped peroxidation and activities of alcohol metabolic enzymes in alcohol-treated rats. Male Spra gue-Dawley rats were given 25% ethanol (Alcohol), 25% ethanol and 5 mg tectorigenin/kg B.W.(Alc.-Tec), 25% ethanol and 5mg kaikasaponin III/kg B.W. (Alc-Kai). The contents of serum total lipid, triglyceride and phospholipid were increased by ethanol treatment and were lower in the Alc.-Tec and Alc.-Kai group than in the Alcohol group. Decreased serum HDL-cholesterol by alcohol treatment was recovered by tectorigenin and kaikasaponin III. Microsomal cytochrome P-450, aniline hydroxylase and aminopyrine N-demethylase activities were increased by ethanol and were lower in the Alc. Tec and Alc.-Kai group than in the Alcohol group. Activity of hepatic alcohol dehydrogenase was increased by ethanol and was higher in the Alc.-Tec and Alc.-Kai group than in the Alcohol group. Microsomal ethanol oxidizing system activity was higher in Alc.-Tec group than in the other group. No significant difference was found in catalase activity among treatment groups. These data indicate that tectorigenin and kaikasaponin III were effected alcohol metabolic enzyme system and the liver damage associated with chronic ethanol consumption.

This study was carried out to investigate the feeding effect of by-products such as ginseng loaves(GL) and stem (GS) which had about 8% of crude saponin on pork carcass and meat quality characteristics when they were fed for 40 days. The ginseng leaves and stem were added in feed and the pigs were slaughtered at 10, 20, 30 and 40 days. The chilled carcass weight and trimmed fat contents were higher(86.50 kg) in the pork fed for 40 days. The yields of fore legs were higher in pork fed for 10 days(P<0.05) and there was no different in the yields of the other portion cuts such as shoulder, rib, loin, belly, hind legs and tenderlons. The incidence of percentages for grade A and B decreased as the feeding periods increased up to 40 days. The backfat thickness was lowest in carcasses from pigs fed up to 20 days(P<0.05). The L values were highest in pork fed up to 30 days(50.22) and lowest(46.91) for pork fed 10 days. The incidence of PSE pork was low in pork fed for 20 days when compared to other feeding days. Cooking loss was lowest and water holding capacity(WHC) was highest in pork fed GL and GS stem, respectively. However, the analysis for accumulation contents of saponin and functionality in pork fed GL and GS is needed in the future research.

The present study was conducted to investigate the effect of dietary supplementation of sea tangle extracts on the excretion of neutral steroids and bile acid in diabetic rats. Sprague-Dawley rats were fed on AIN-76 based experimental diets containing methanol extracts (2%, w/w) or water extracts (4%, w/w) of sea tangle for 4 weeks. And then they were induced to be diabetic by receiving streptozotocin (45 mg/kg BW) intramuscularly. The dried fecal weight was increased significantly in water extracts group compared with control group. The fecal content of cholesterol was higher in extracts groups of sea tangle than in control group. But there was no significant difference in fecal excretion of cholesterol between methanol and water extracts groups. The fecal excretion of coprostanol was increased significantly in water extracts group compared with the control group. The fecal excretion of bile acid was increased significantly in sea tangle extracts groups compared to the control group. These data suggest that dietary supplementation of sea tangle extracts might reduce the incidence of atherosclerosis through increasing the excretion of neutral steroids.
