This study was conducted to evaluate the effect of whole egg supplementation on the blood lipid profiles and cholesterol levels of C57BL/6 mice. Sixty-six mice were divided into two groups: normal-diet supplemented and high-cholesterol diet supplemented. Lyophilized whole egg powder was mixed with the two diets at 2 and 10%: normal diet only, normal diet with 2 and 10% whole egg powder, high cholesterol diet only, high cholesterol diet with 2 and 10% whole egg powder. The mixed diets were fed for 5 wk and feeding condition (body weight change, feed intake, and feed efficiency ratio (FER)), blood lipid profiles (total cholesterol (TC), triglyceride (TG), high density lipoprotein-cholesterol (HDL-C), low density lipoprotein cholesterol, hepatic and fecal lipids (TG, TC)), and fecal bile acids were determined. No significant differences were found in body weight gain or FER after whole egg supplementation in both the normal and high-cholesterol diet fed groups. In the normal-diet fed mice, HDL-C increased significantly in the 2 and 10% whole-egg powder groups. In the high-cholesterol diet fed mice, administering 10% egg powder increased the atherogenic index compared to the control. Furthermore, administration of whole egg powder increased fecal bile acids dose dependently (p<0.05). These results indicate that administering 2% hen whole egg powder did not affect blood lipid profiles and was more beneficial for health by increasing HDL-C and aiding in the excretion of cholesterol by fecal bile acids than those in the control.

This experiment was conducted to investigate the effects of drinking of Rhus tree-extract on laying performance and egg quality in hens. Four hundred eighty, 55-wk-old ISA brown, laying hens were divided into six groups, control, Rhus tree-extract 500 ppm, 1,000 ppm, 2,000 ppm, 3,000 ppm and 5,000 ppm. The hens were fed a supplemented drink containing Rhus tree-extract for 12 weeks. Egg production and egg mass increased by drinking Rhus tree-extract (p<0.05) and the feed conversion ratio also improved in Rhus tree-extract groups. Cecal numbers of Lactobacillus spp., E. coli and Salmonella were not different in treatments. Availability of protein and ash improved in the Rhus extract groups. The eggshell breaking strength and egg shell thickness were significantly increased in Rhus tree-extract 3,000 ppm and Rhus tree-extract 2,000 ppm groups compared to the other groups. Also, egg yolk color and Haugh unit were significantly improved by the dietary Rhus tree-extract (p<0.05).

This study was compared the effect of shelf-life and DHA accumulation in chicken meat from broilers fed experimental diets for two weeks($21{\sim}35$ days) of growers. Two hundred-ten male Ross broilers, 1 day of age, were randomly allocated to seven treatment groups. Experimental diets were assigned to each of the seven groups: control diet containing tallow, T1 with 1.00% fish oil, T2 with 2.00% fish oil, T3 with 2.00% fish oil, 200 ppm vitamin E and 200 ppm vitamin C, T4 with 2.00% fish oil and 200 ppm vitamin C, T5 with 2.00% fish oil and 200 ppm vitamin E, and T6 with 3.00% fish oil. The levels of DHA in chicken meat was the highest in T6, and T1 in breast muscle and thigh muscle with skin was higher than that of $T2{\sim}T5,\;T2{\sim}T5$ in raw chicken meat and wing with skin was about two-fold higher than that of T1. The contents of DHA in chicken meat according to storage days were significantly reduced to 42.30%, 49.38% and 48.51% in T1, T2 and T6, respectively, and this decrease was higher than that of T3, T4 and T5 (p<0.05). Particularly, the rate of reduction of DHA was the lowest in the T3 and T5, which were the lowest in TBARS(thiobarbituric acid reactive substances). TBARS increased in the order of T6, T2 and T1, but reduced in the order of T3, T5 and T4 according to storage days, and there was a significant difference among the treatment groups (p<0.05).

The present study was made in order to clarify the anti-emetic effect by needle-acupuncture (AP), injection-AP and moxibustion in xylazine - induced vomiting of dogs. Twelve mongrel dogs (4 months to 5 year old, 2 to 4 kg of body weight), eleven mongrel dogs (4 months to 5 years old, 2 to 10 kg of body weight) and twelve mongrel dogs (4 months to 1 year old, 2 to 4 kg of body weight) were used for clarification of anti-emetic effect by needle-AP, injection-AP and moxibustion, respectively. The experimental animals were devided into control(6 heads), BL-21(6 heads), CV-12(6 heads) and BL-21+CV-12(6 heads) groups using total 6 dogs with vomiting selected in preliminary experiment, respectively in needle-AP treatment. In addition, the experimental dogs were divided into control (11 heads), BL-21 (6 heads) and CV-12(6 heads) groups using 11 dogs, respectively in injection-AP treatment. In moxibustion treatment the experimental dogs were divided into control (6 heads), BL-21(6 heads) and CV-12(6 heads) groups using 6 dogs, respectively. Five days after the experiment of one group was finished, the other group was examined in each experiment. Acupuncture needle was maintained for 20 minutes in needle-AP treatment. Metoclopramide was used in injection-AP treatment. Commercial moxa was used in moxibustion treatment. Vomiting was induced by intramuscular injection with $2{\%}$ xylazine 20 minutes after treatments of needle-AP, injection-AP and moxibustion, respectively. The vomiting rates of BL-21($33.3{\%}$), CV-12($50{\%}$) and BL-21+CV-12($33.3{\%}$) were lower than that of control($66.7{\%}$) and vomiting times of experimental groups were similar to that of control in needle-AP treatment. The vomiting rates of BL-21 ($0{\%}$) and CV-12($16.4{\%}$) were lower than that of control($66.7{\%}$) and the vomiting time of CV-12 group was similar to that of control group in injection-AP treatment. The vomiting rates of BL-21($33.3{\%}$) and CV-12($33.3{\%}$) were lower than that of control ($66.7{\%}$) and vomiting times of experimental group were similar to that of control group in moxibustion treatment. In conclusion, it was considered that needle-AP, metoclopramide injection-AP and moxibustion at BL-21 and CV-12 were effective for anti-emesis in xylazine induced vomiting of dogs and metoclopramide injection-AP was the most effective method for anti-emesis among them.

Two cases of canine intervertebral disc disease (IVDD) were treated twice a week with injection-acupuncture (injection-AP) using 0.1 ml/acupoint. In case 1, a paralysed dog with cervical intervertebral disc disease (C3-C4), was submitted to injection-AP with dexamethasone (1 mg/ml) at session 1-2 and thiamine (25 mg/ml) at session 3-5. Injected acupoints included GV-16, GB-20, BL-10, LU-7, LI-4 and SI-6. The acupoints GV-6, GV-20 and SP-6 were added at session 2-5. Trigger point (TP) therapy with 0.2 ml of 2% lidocaine was used in session 3-5 at TP in the infraspinatus and triceps muscles. Treatment was stopped when paralysis disappeared after 5 injection-AP treatments; there were no recurrent symptoms in the follow-up period of 5 months. In case 2, an ataxic dog with lumbar IVDD (L1-L2), was submitted to injection-AP with dexamethasone at session 1 and 2 and thiamine at session 3-4. Injected acupoints included GV-6 as the main point, ST-36, GB-30, ST-40, GB-34, ST-41 and BL-40. TP therapy with 0.2 ml of 2% lidocaine was used at TP in the ileocostorum lumborum and quadriceps muscles. Treatment was stopped when ataxia disappeared after 4 treatments; there were no recurrent symptoms In the fallow-up period of 5 months. Injection-AP using dexamethasone and thiamine, combined with TP therapy using lidocaine, effectively alleviate the symptoms of canine cervical and lumbar IVDD.

The present study was performed to elucidate the recovery effect of needle-acupuncture (needle-AP) and moxibustion treatments at Gan Shu (BL18) on $CCl_4$ induced hepatic injury in dogs, Total 9 clinically healthy experimental dogs (1 to 2 years old, 2.3-5.3kg body weight) were divided into control (3 dogs), needle-AP (3 dogs) and moxibustion (3 dogs) groups, respectively. Hepatic iniw was induced by intraperitoneal injection with $CCl_4$ (olive oil : $CCl_4=1:1,\;1ml/kg$, once/day). As far the treatments in each group, control group was not treated at all after induction of the hepatic injury till the end of experiment. Needle-Af group was treated by AP at BL18 (once/day, 20 minutes) from the next day of induction of the hepatic injury for 11 days. Moxibustion group was also treated with commercial moxa at BL18 (once/day, 20minutes) for 11days. The changes of the serum alanine transaminase(ALT), aspartate transaminase(AST) and gamma glutamyl transpeptidase (GGT) activities were investigated on pre, 0, 1, 3, 5, 7 and 11 days after hepatic injury, respectively. Histopathological changes were also investigated in the liver tissues on day 11 in experimental and control groups. The results obtained in the present study were as follows. In needle-AP group, they showed significant lower values on the 1st (p<0.05) and $3^{rd} day (p <0.05)$ in serum ALT activities, and the $11^{th}$ day in serum GGT activities, compared with those of control group, respectively. However, the significances were not detected in serum AST activities of needle-AP group by comparison with those of control group. In moxibustion group, they showed significant low values on the $1^{st}(p<0.05)$, 3rd day (p<0.05) and $5^{th}$ day (p<0.05) in serum ALT activities, compared with those of control group, respectively. However, significances were not detected in serum GGT and AST activities of moxibustion group by comparison with those of control group. Among the experimental groups, the significant low values were found on $1^{st}\;and\;3^{rd}$ day in serum ALT activities (p<0.05), and $3^{rd}\;and\;5^{th}$ day in serum GGT activities (p<0.05) in needle-AP group, compared by those of moxibustion group, respectively. In addition, the marked recovery findings of histopathological changes in experimental groups were found, compared by those of control group: mild vacuolar degeneration and necrosis findings in needle-AP group, and moderate vacuolar degeneration and necrotic findings in moxibustion group were found, in contrast to severe changes such as accumulation of bile juice, vacuolar degeneration and necrotic findings observed in control group. In conclusion, needle-AP and moxibustion treatments at BL-18 were effective for the recovery for $CCl_4$ induced hepatic injury and needle-AP was more effective than that of moxibustion in dogs.

The purpose of this study was to evaluate the effect of estrogen on the periodontium and alveolar bone tissue response during experimental tooth movement in ovariectomized rats. Eighty female rats, 250gm in body weight, were classified into four groups ; sham operated group(NN), ovariectomized group(ON), ovariectomized & estrogen injected group(OE), sham operated & estrogen injected group(NE). flats were ovariectomized before 3 weeks to begin the experiment, which resulted in estrogen-deficient osteoporosis. In OE group & NE group, estrogen was injected $50{\mu}g/kg\;B.W.$ every other days. The left maxillary 1st molar was moved mesially with 60g force. Each foot rats were sacrificed after 1, 3, 7, 15 days from application of orthodontic appliance and alter additional 7 days from removal of orthodontic appliance. Histological findings on mesial roots of upper 1st molar in pressure and tension side are observed. The results were summarized as follows ; 1. In pressure side of alveolar bone, the number of osteoclasts and Howship's lacuna of ON group was significantly more than that of NN group from 1 day to 15 days(P<0.05). Especially the number of Howship's lacuna of ON group was significantly more than that of OE group during all experimental period(P<0.05). 2. In tension side of alveolar tune, the number of osteoclasts of ON group was significantly increased from 1 day to 3 days and decreased after 7 days. But the number of osteoclast of ON group was significantly mote than that of NN group during all experimental period(P<0.05). Also the number of Howship's lacuna of all groups was abruptly increased at 1 day, but slowly decreased till experimental 15 days. And the number of Howship's lacuna of of group was significantly more than that of NN group from 0 hr to 7 days(P<0.05). 3. The speed of tooth movement of OE group & NE group was similar to that of NN group(P>0.05). The amount of tooth movement of ON group between 7 days and 15 days was significantly greater than those of other groups(P<0.05). 4. The degree of relapse of ON group after 7 days from removal of orthodontic appliance was similar to those of other groups(P>0.05).

Objective : This study is aimed to examine the degree of independence in stroke patients residing in a community based on their self-efficacy and Instrumental Activities of Daily Living and also correlation between community-residing stroke patients and their guardians by figuring out the life quality of their guardians. Methods : For total two weeks between May 12th and 23rd, 2014, this researcher collected data by using a survey (K-IADL, a scale to measure self-efficacy, WHOQOL-BREF) targeting 138 stroke patients who received over 24 points in MMSE-K among the outpatients of three hospitals located in Busan Metropolitan City and two hospitals located in Geoje-si, Gyeongsangnam-do, and total 125 sheets were finally used for analysis. Results : Among the 125 patients, 70 were males, and 55 were females, and their average age was 58.72 (16 to 82). The subjects' general self-efficacy (p<0.01) and detailed self-efficacy (p<0.01) indicated significant correlation with their guardian's life quality, and there was no significant correlation found between their Instrumental Activities of Daily Living and their guardian's life quality. Conclusion : Their general self-efficacy and detailed self-efficacy indicated correlation with their guardian's life quality, and among their general characteristics, the factor of their financial situation indicated correlation with their guardian's life quality. In conclusion, when stroke patients' self-efficacy is higher, their guardian's life quality increases, too, and if their financial situation is more favorable, their guardian's life quality gets higher. However, stroke patients' Instrumental Activities of Daily Living did not indicate correlation with their guardian's life quality. When looking at the chronic trend of outpatients, therapeutical plan must be established about the self-efficient recovery for the development of those who are not satisfied.
