Objectives : The purpose of this investigation is to evaluate and compare the effects of Sunghyangjunggi-san (SH) and Gwackhyangjunggi-san (GH) extracts on reperfusion following the MCA occlusion in rats. Methods : To evaluate the effect of Sunghyangjunggi-san (SH) and Gwackhyangjunggi-san (GH) extracts on reperfusion following the MCA occlusion, the volume of cerebral infarction and edema were measured and the change of the CA1 pyramidal neurons in the hippocampus were investigated by light microscopy. Results : 1. The infarction volume of the control group was 23.6%, that of the GH group was 23.7%, and that of the SH group was 18.5%. 2. The brain edema volume of the control group increased by 16% compared with that of the normal group, that of the GH group increased by 14%, and that of the SH group increased by 9%. 3. The number of surviving pyramidal neurons in the CAI area of the hippocampus was investigated under light microscopy. In the control group, few surviving pyramidal neurons excisted (mean 6.4) and similarly in the GH group (mean 8.5), but in the SH group, the number of surviving pyramidal neurons was significantly higher, to the mean 18.4. Conclusions : According to the above results, in regard to the damage of neurons following cerebral ischemia, the GH group has little effect of the protection of neurons compared to the control group, but the SH group has a remarkable effect.

The research was designed to study the effect of different fat sources and levels on Body lipid metabolizm and immune responses in Sprague-Dawely strain male rats. These effect of different fat sources compared with sesame Oil, Perilla oil and Beet tallow. Fat sources were divided into 3 groups respectively 7%, 15%, 30% fat level on diet weight basis. The experimental period was 54days. 1) The body weight gain was significantly low in NF group. In Sesame oil group and perilla oil group, low fat level groups were higher than medium, high fat level groups. But in Beef tallow group, high fat level groups were higher than low and Medium groups. 2) The weight of liver, kidney and epididymal fat ped tend to increse with increasing body weight. 3) The contents of triglyceride and total lipid in serum were significantly different with dietary fat sources and Perilla oil group was the lowest. 4) The contents of triglyceride and total lipid in liver were significantly different with dietary fat levels and high fat level group was higher than low fat level group. 5) Perilla oil group, compared with Beef tallow group, showed the higher excretion of cholesterol through feces and the higher deposit of cholesterol in liver. Therefore serum cholesterol level of Perilla oil group was lower than that of Beef tallow group. But eventhough Sesame oil is vegetable oil, Sesame oil did not showed an effect like Perllia oil on serum cholesterol level. 6) Weight of thymus decreased with fat levels particularly in vegetale oil. And it had on effect on mitogen response, mitogen response decreased with fat level in vegetable oil. But in Beef tallow, there was no difference in fat level.

The authors screened the pharmacological effects of 50% ethanol extracts of Yacon on spermatogenesis in rats. Numbers of sperm in animals treated with 25, 50, or 100 mg/kg/day for 6 weeks of Yacon tuber extracts (YTE) were approximately 1.51, 1.61 and 1.78 times higher, respectively, than in the untreated control group. Moreover, the spermatogenic effect of Yacon leaf extract was found to be $1.03{\sim}1.38$ times higher than that of YTE. The ameliorative effect of Yacon tuber extracts on 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) induced toxicities in the rat were also investigated. Rats were assigned to three groups (6 rats/group), a control group, a TCDD exposed group, and a group treated with Yacon tuber extract (YTE) after TCDD exposure (TCDD/YTE group). 40 ${\mu}g/kg$ of TCDD was injected i.p., and 200 mg/kg/day of YTE was also administered for 4 weeks by oral gavage. The TCDD/YTE group showed a significant increase in sperm number as compared with the TCDD exposed group. In conclusion, TCDD induced testicular toxicity was significantly ameliorated by YTE. The results of the present study suggest that Yacon extract is a possible therapeutic for the treatment of spermatogenic disorder.

In order to investigate the preventive and therapeutic of royal jelly on diabetes, the levels of blood glucose and serum lipids as well as the number of blood cells were determined in streptozotocin(STZ) diabetic rats. Rats were divided into seven groups. The RJ group was administered royal jelly and the STZ group was treated with streptozotocin to induce diabetes. To determine the preventive effect, diabetes was induced after administration of royal jelly for 2 weeks in group RS1/RS2. In group SR1/SR2 diabetic rats were administered royal jelly for 2 weeks to investigate the therapeutic effect. After 3 weeks, the body weight was reduced in STZ and SR1 groups and food intake was increased in the STZ, RS1 and SR1 groups. The blood glucose level was similar to the control group in the RJ, RS1 and RS2 groups and there was no effect in the other groups. The total lipid and triglyceride level were lower in the SR1 group as compared to STZ, and the total cholesterol level was higher in the STZ group. The index of atherogenesis was lower in the RJ and SR1 groups compared to the normal group. The number of red blood cells and hemoglobin was higher in the RJ and SR1 groups and the number of white blood cells was higher in the RJ and SR2 groups.

In order to compare and examine the effect the effect of Kuibitang, Kamiondarmtang and Kuibiondarmtang against stress, I induced immobilization stress by binding rats for 200mins under a little anesthetized with ether. I classified as normal group, control group which administrated 0.9% NaCl solution, sample A group which administrated Kuibitang, sample B group which administrated Kamiondarmtang and sample C group which administrated Kuibiondarmtang. I got some conclusions by measuring amounts of norepinephrine, epinephrine, triiodothyronine($T_3$) and thyroxine($T_4$) in 1, 3 and 5 days, respectively. 1. Norepinephrine showed high meaningful decrease after 1. 3 and 5 days in sample A group. It showed little decrease in sample B group. It showed a little meaningful decrease after 1 day and high meaningful decrease after 3 and 5 days in sample C group. 2. Epinephrine showed high meaningful decrease after 3 and 5 days in sample A group. It showed little decrease in sample B group. It showed a little meaningful decrease after 3 days and high meaningful decrese after 5 days in sample C group. 3. Triiodothyronine($T_3$) inclined to approach normal value in sample A, B, C group in comparision wit control group but didn't have high meaning. 4. Thyroxine($T_4$) inclined to approach normal va1ue in sample A, B, C group in comparision with contrl group but didn't have high meaning. As I consider the effect of experiments, I think that Kuibitang and Kuibiondarmtang have some effects against stress and it is right to apply to the treatment of stress.

Two trials were carried out during two different grazing seasons to evaluate effect of grass silage supplementation, when amount of pasture is limited on dry matter intake (DMI), milk production, and gross energetic efficiency (GEE) of grazed lactating cows on a high forage-based diet. Fifty-one Holstein cows were randomly assigned to one of two dietary treatments: high pasture group or high silage group. In the spring flush, pasture and silage DMI, milk yield, milk fat percentage, and GEE were not different between the dietary groups. After the spring flush, pasture and silage DMI were higher for the high silage group than for the high pasture group. After the spring flush, although these were the higher total DMI of the high silage group than the high pasture group, milk yield was significantly (p<0.05) higher for the high pasture group than the high silage group. Milk fat percentage tended to be higher for the high silage group than the high pasture group. The GEE was significantly (p<0.05) higher for the high pasture group than the high silage group during after the spring flush. This study indicated that supplementation of grass silage, especially after the spring flush, can have a significant effect of increasing of forage intake and maintenance of the milk fat percentage; but not increase milk yield and GEE.
