Blockade of cervicothoracic sympathetic ganglion (stellate ganglion controls pain on face, head, neck, shoulder, upper limbs, and upper chest, including their viscera and sympathetically maintained pain. This procedure also increases blood flow to the above areas and relieves hyperreactivity of sympathetic nervous system. Clinically, repeated stellate ganglion blocks with local anesthetic agent may become difficult with complications such as accidental intravascular or subdural injection, recurrent laryngeal nerve or bracheal plexus paralysis, pneumothorax and edema on injection site. Therefore, at times long-term cervicothoracic ganglion block with neurolytics is necessitated but its applications are prohibited by the critical structures surrounding ganglion. There are also few reports of neurolytic stellate ganglion block. This study was performed to observe the complications, gross changes of surrounding structures, and microscopic findings of ganglion cells after neurolytic block and to certify the possibility of clinical use of neruolytic stellate ganglion block. The unilateral superior cervical sympathetic ganglion of rabbit was blocked with absolute ethyl alcohol 0.4 ml at the level of cricoid cartilage. Normal ganglion was used as a control and 5 animals were sacrificed at each intervals of 7, 15 and 50 days after block. The results were as follows; 1) All experimental animals showed no specific changes of behavior, motor function. No necrotic tissues were present in the block area during the observation period. There were some gross scar tissues along the fascia of muscles surrounding the needle injection site, but gross atrophy of muscles or injured major vessels were not found. 2) Microscopically, structures of normal ganglion of rabbit were very similar to those of humans. Seven days after absolute ethyl achohol injection there were marked edema of ganglion cells and nuclei with irregular nuclear membrane. Some of the ganglion cells lost their nuclei and showed degenerative changes. Fifteen days after block, cell edema were decreased and loss of the Nissl's body was prominant. The ganglion cell structures looked close to normal but the cytoplasm and nucleus were generally contracted 50 days after block. These results suggest absolute ethyl alcohol injection on cervical sympathetic ganglion with above method mainly blocks pre- and post-synaptic fibers and the long-term neurolytic blockade of this ganglion may be possible in rabbits.

Many Lactobacillus strains have been promoted as good probiotics for the prevention and treatment of diseases. We engineered recombinant Lactobacillus casei, producing biologically active canine granulocyte macrophage colony stimulating factor (cGM-CSF), and investigated its possibility as a good probiotic agent for dogs. Expression of the cGM-CSF protein in the recombinant Lactobacillus was confirmed by SDS-PAGE and Western blotting methods. For the in vivo study, 18 Beagle puppies of 7 weeks of age were divided into three groups; the control group was fed only on a regular diet and the two treatment groups were fed on a diet supplemented with either $1\times10^9$ colony forming units (CFU)/day of L. casei or L. casei expressing cGM-CSF protein for 7 weeks. Body weight was measured, and fecal and blood samples were collected from the dogs during the experiment for the measurement of hematology, fecal immunoglobulin (Ig)A and IgG, circulating IgA and IgG, and canine corona virus (CCV)-specific IgG. There were no differences in body weights among the groups, but monocyte counts in hematology and serum IgA were higher in the group receiving L. casei expressing cGM-CSF than in the other two groups. After the administration of CCV vaccine, CCV-specific IgG in serum increased more in the group supplemented with L. casei expressing cGM-CSF than the other two groups. This study shows that a dietary L. casei expressing cGM-CSF enhances specific immune functions at both the mucosal and systemic levels in puppies.

Rumen bypass fat is commonly added to increase energy intake in dairy cattle. The objective of this study is to examine the addition of rumen bypass fat during finishing period on performance and carcass characteristics in grain fed steers. This study was conducted as a completely randomized block design with 126 cross-bred steer calves (initial BW $471.5{\pm}7.5kg$) randomly assigned to pens with 9 steers/pen (n = 7 pens/treatment). Each pen was randomly assigned to one of two treatment groups; rumen bypass fat treatment (CCS, calcium soap of palm fatty acids) and control diet (CT, tallow). The diets were formulated to be isonitrogenous and isocaloric. Animals were fed twice daily at 110 % of the previous daily ad libitum intake. Blood from each sample was taken from the jugular vein. Muscle and adipose samples were collected from the longissimus dorsi regions. Feedlot performance and carcass characteristics were assessed. To examine adipogenic gene expression, quantitative real-time PCR was completed. Steers fed the CT had a greater level of performance for most of the parameters measured. The CT group had greater DMI (P < 0.05) and tended to have greater ADG (P < 0.10). Marbling score (P < 0.05) and quality grade (P < 0.05) were greater for steers fed the CT diet than those fed CCS. The longissimus muscle area tended to be greater (P < 0.10) in steers fed CT ($87.60cm^2$) than those fed CCS (84.88 cm2). The leptin mRNA expression was down-regulated (P < 0.05) in adipose tissue of steers fed a CCS when compared to those fed CT. These data suggest that calcium soap of palm fatty acids can be added to finishing diets without significant reduction in final body weight, although there may be modest reductions in marbling and quality scores.

Two experiments were conducted to investigate the feeding influence of wood vinegar and mixed with probiotics on performance and physiological related of broiler chicks for five weeks. Diets contained 21.5%, 3,100kcal/kg and 19.0% CP, 3,100kcal/kg ME for starting and finishing period, respectively. In Expt 1, Four levels of wood vinegar(0, 0.05, 0.10, 0.20%) were fed into two hundred forty chicks with four replicates. In Expt 2, 0, 0.1% wood vinegar(W), 0, 0.1% lactobacillus casei(L) and bacillus subtilis (B) were applied to 2${\times}$2${\times}$2 facotrial design for eight treatments with four replicates. Weight gain, feed intake, feed cholesterol were detected at five weeks old in each experiment. In Expt 1, Weight gain of chicks fed 0.1% wood vinegar(WV) was increased upto 1645.8g, but was not significantly different. However, chicks fed 0.2% WV showed the highest gain and siginificantly different compared to that of control (P＜0.05) for finishing period. Feed intake also showed similar tendency with weight gain. There were no statistical difference in feed conversion. Abdominal fat seemed to be decreased in WV supplemental groups, whereas ND antibody titer tended to increase in those treatments. In Expt 2, 0, 0.1% WV, lactobacillus, bacillus were combined with each other(W$\sub$0/L$\sub$0/B$\sub$0/, W$\sub$0/L$\sub$1/B$\sub$0/, W$\sub$0/L$\sub$0/B$\sub$1/, W$\sub$0/L$\sub$1/B$\sub$1/, W$\sub$1/L$\sub$0/B$\sub$0/, W$\sub$1/L$\sub$1/B$\sub$0/, W$\sub$1/L$\sub$1/ B$\sub$0/, W$\sub$1/L$\sub$0/B$\sub$1/, W$\sub$1/L$\sub$1/B$\sub$1). WV supplemental groups significantly improved feed conversion of all treatments(P＜0.05). There were no interaction in weight gain and feed intake. Total cholesterol was signficantly decreased in WV plus lactobacillus and ladtobacillus plus bacillus treatments. Liver to body ratio(%) of lactobacillus plus WV significantly decreased compared to that of other treatments. The results of these experiments showed that wood vinegar tended to improve the performance of broiler chicks, but was not effect in its combination with lactobacillus or bacillus treatments.

비태인이 산란계의 면역 반응에 어떠한 영향을 미치는지 알아보기 위하여 in vitro와 in vivo 시험을 시행하였다. 처리구당 18수씩 총 72수를 공시하였고, 비태인 0, 300, 600, 1,200 ppm 수준으로 산란계 사료에 첨가 급여하였다. 시험결과, in vitro 시험에서 비장 림프구 증식은 비태인 만을 처리하였을 때에는 증식 반응은 일어나지 않았으나 Con A와 PWM을 처리하였을 때 증식 반응은 현저하게 증가하였다. 또한 Con A만을 처리했을 때보다 Con A와 비태인을 동시에 처리했을 때 반응성이 현저하게 증가하였다. 그러나 PWM과 비태인을 동시에 처리했을 때는 PWM만을 처리했을 때와 비교해서 차이를 보이지 않았다. 사료에 비태인을 첨가 급여한 in vivo시험에서 Con A의 자극에 대한 비장 림프구 증식반응은 비태인의 첨가 수준에 따라 증가하는 경향을 보였으나 1,200 ppm 급여구에서는 대조구에 비하여 감소하는 경향을 보였다. 이러한 경향은 Con A와 함께 비태인(0.1 mM)을 처리했을 때도 동일하게 나타났다. PWM의 자극에 대한 반응은 Con A에 비하여 약하게 나타났으며 비태인 급여 수준에 따른 차이도 적게 나타났다. 비태인을 급여한 산란계 비장의 무게에서 처리구간에 통계적인 차이는 없었다. 비태인 첨가구는 대조구에 비하여 전체적으로 증가하는 경향을 보였고, 비태인 300 ppm 첨가구가 가장 높은 수치를 나타내었다. 비태인을 수준별로 급여하여 SRBC 항체가를 조사한 결과에서도 처리구간 유의적인 차이는 나타나지 않았다. 따라서 본 시험의 결과, 비태인의 처리는 in vivo 상에서 Con A로 비장 림프구의 증식을 유도한 경우 유의하게 비장 림프구의 증식을 증가시켰다.

Objective : The effects of Indium-Gallium-Aluminium-Phosphide(InGaAlP) laser transcutaneous irradiation on heart rate variability(HRV) in healthy adults are investigated with power spectrum analysis(PSA) of HRV. Methods : The control group consisted of 20 healthy volunteers (10 men, 10 women). The experiment was divided into 5 different periods, the pre-1st laser period(10 minutes), the 1st laser period(30 minutes), the post-1st laser period(5 minutes), the 2nd laser period( 30 minutes) and the post-2nd laser period(30 minutes). HRV was measured for 5 minutes at the pre-1 st laser period, the post-l st laser period and the post-2nd laser period. The laser period is the period in which InGaAlP laser transcutaneous Irradiation treatment occurs. Results : 1. SDNN of volunteers at post-1st laser period and post-2nd laser period significantly increased compared with that of the pre- 1 st laser period. 2, Ln(VLF) at post-I st laser period significantly increased compared with that of pre-1st laser period, while Ln(HF) at post-2nd laser period significantly decreased compared with those of pre- I st laser period and post-1st laser period, 3. Ln(TP) at post-1st laser period and post-2nd laser period significantly increased compared with that of pre-1st laser period, 4, LF/HF Ratio at post-2nd laser period significantly increased compared with those of pre-1st laser period and post-1st laser period. But the other variables did not significantly change. Conclusions : The results suggest that InGaAlp laser transcutaneous Irradiation in healthy adults is associated with the autonomic nervous systems. Further study is needed for investigating the effects of laser irradiation on autonomic nervous systems.

Objectives: The purpose of this study was to investigate the effects of Hyolbuchukeo-tang extracts on the hyperlipidemia rats induced by high fat diet. Methods and Materials: In vitro; The extracts prepared for Hyolbuchukeo-tang by hot water extraction (HH), fermentation(HF) and UMPM extraction(HU) method. The extracts were examined for levels of polyphenol compounds, antioxidant activities, and inhibitory potencies for HMG-CoA reductase. In vivo; Sprague-Dawley male rats of weighing $150{\pm}5g$ were randomly divided into six groups ; normal control diet(NC), and high fat diet(HC), high fat diet with treated lovastatin of 10mg/kg(PC), high fat diet with Hyolbuchukeo-tang extracts; HH, HF and HU treated extracts of 300mg/kg, respectively. Also, we compared the effects of the extracts of HH, HF and HU on rats fed high fat diet for four weeks. Results: 1. The content of polyphenol compounds and electron donating abilities(EDAs) was the HF higher than HH and HU. The superoxide dismutase(SOD)-like activities were proportionate in consistency and they appeared highly from all extracts. The HMG-CoA reductase inhibition activities was highest activities in the HU. 2. The activities of serum GOT and GPT were significantly lower in the HH and HF groups. The level of serum triglyceride was significantly decreased in the HF group. HH and HU groups were significantly decreased in the atherogenic index(AI). The total cholesterol concentration in liver was significantly decreased in the HF group, and HU showed more significantly decreased in the triglyceride than of the lovastatin. Also, photomicrographs of liver tissue showed higher fat accumulation in the HC group than in the HH, HF and HU groups. Conclusions: These result suggest that the hyper-lipidemia caused by a high fat diet was effectively inhibited the administration of HF and HU.

Knowledge of the prevalence of human Toxoplasma gondii infection is required in the Republic of Korea. In this study, we surveyed the seroprevalence of T. gondii infection and analyzed the risk factors associated with seropositivity among residents in 2 administrative districts; Seoul and the island of Jeju-do, which have contrasting epidemiologic characteristics. Sera and blood collected from 2,150 residents (1,114 in Seoul and 1,036 in Jeju-do) were checked for IgG antibody titers using ELISA and for the T. gondii B1 gene using PCR. In addition, participants completed a questionnaire that solicited information on gender, age, occupation, eating habits, history of contact with animals, and travel abroad. The T. gondii B1 gene was not detected in all residents examined. However, ELISA showed 8.0% (89 of 1,114 sera) positive for IgG antibodies against T. gondii in Seoul and 11.3% (117 of 1,036 sera) in Jeju-do. In both districts, the positive rates were higher in males than in females, and those 40-79 years of age showed higher rates than other ages. In Seoul, residents older than 70 years of age showed the highest positive rate, 14.9%, whereas in Jeju-do the highest prevalence, 15.6%, was in those in their sixties. The higher seropositive rate in Jeju-do than in Seoul may be related to eating habits and occupations. The present results and a review of related literature are indicative of an increased seroprevalence of T. gondii in Korea in recent years.

The purpose of this research was to investigate the effects of dried orange peel compound intaking and exercise training on the physique, body fat, and concentration bloodlipid in obese women. Ninety-seven volunteers(mean age 21.47 ${\pm}$ 1.47 yrs), all over 30% of body fat, agreed to Participate and were placed in 4 groups: dried orange peel compound intaking and exercise group(n=25), only exercise group(n=25), only dried orange peel compound intaking group(n=24), and control group(n=20). The subjects who joined this project were asked to take dried orange peel compound(2 times/day, 30 ml/time) or participate in exercise program(3 times/week, 70 min/day), depending on particular group for 12 weeks. They were tested on their height, weight, circumference of chest, abdomen, hip, and thigh, body fat%, total-cholesterol(TC), HDL-C, LDL-c, and triglyceride(TG) at the beginning and the end of the 12-weeks program. For data analysis, paired t-tests and ANCOVAs were used. The intaking of dried orange peel compound was influenced on weight, circumference of chest, abdomen, hip, and thigh, body fat%, HDL-C, LDL-C, and TG. The exercise participation had almost same effects on those dependent variables. Furthermore, the dried orange peel compound intaking along with exercise training was the most effective on those dependent variables among them. Therefore, these results indicate that dried orange peel compound intaking, like exercise, may be useful for controling weight, body fat, HDL-C, LDL-C, and TG.
