  • Effects of squalene on cellular and non-specific immune responses and antitumor activity in mice were investigated. Cellular and non-specific immunological assay parameters adopted in the present study were delayed-type hypersensitivity reaction and resette forming cells (RFC) for cellular immunity, activities of natural killer (NK) cells and phagocyte for non-specific immunity. Squalene resulted in marked increases of cellular and non-specific immune functions and enhancement of host resistance to tumor challenge in dose-dependent manner.

  • Background: The immunomodulatory effects of Korean mistletoe (Viscum album Coloratum) on the innate immune responses of eel (Anguilla japonica) were studied. Methods: Mistletoe, Freund’s complete adjuvant (FCA), or phosphate-buffered saline (PBS) as a control was injected into eel peritoneal cavities. Results: Nitroblue tetrazolium (NBT)-positive cells in the head kidney of eel were significantly augmented by the second day post-injection of mistletoe. Reactive oxygen intermediates (ROI) were more produced in mistletoe-injected fish kidney leucocytes than in FCA-injected ones. The level of lysozyme activity in the serum of fish 2 days after injection with mistletoe was also significantly higher than that in the serum of the control fish. The optimal concentration of mistletoe in inducing the highest serum lysozyme activity was revealed to 500${\mu}$g/200 g of fish. In phagocytic activity assay, mistletoe-sensitized eel kidney phagocytes captured more zymosan than did the control fish. Conclusion: Korean mistletoe appeared to be a good activator of the non-specific immune responses of eel.

  • Effects of quercetin on the specific and non-specific immune responses were studied in vivo. Quercetin at a dose of 2.5, 5, 10, 20 and 40 mg/kg were orally administered to ICR male mice once daily for 28 consecutive days. Cyclophosphamide was injected intraperitoneally to ICR mice with a single dose of 5 mg/kg 2 days before secondary immunization. Mice were sensitized and challenged with sheep red blood cells (S-RBC). Immune responses were evaluated by humoral and cellular immune reponses and non-specific immune response. The results of this study were summarized as followings; 1. Quercetin significantly decreased the body weight, and introduced the atrophy of liver, spleen and thymus gland dose-dependently, but increased the numbers of white blood cell. 2. Querectin significantly depressed the hemagglutination titer, Arthus reaction and hemolytic plaque forming cell. 3. Quercetin significantly depressed the delayed type hypersensitivity and rosette forming cell. 4. Quercetin at a dose of 2.5, 5 and 40 mg/kg significantly depressed phagocytic activity. 5. Quercetin at a dose of 10 and 20 mg/kg significantly increased natural killer cell activity.

  • This study was performed to determine the effect of maternal protein intake on 1) the concentration of immune substances in milk 2) degree of passive immunity to pups via lactation, and 3) specific antibody production to a specific antigen, $\beta$-lactoglobulin(BLG). 4) the effect of passive immunity that pups received from mother during lactation on the production of antibodies when the pups were challenged to the same antigen. Part of the female rats were immunized with BLG before and during pregnancy. The pregnant rats were placed into either 25% or 10% isolated soy protein diet throughout gestation and lactation. After weaning, pups from each group continued to be fed the same diet. At 18 weeks of age, all the pups were challenged with BLG. Total IgA and IgG, lysozyme, BLG-specific IgA and IgG were measured in dam's serum, dam's milk, and pup's serum. Total IgG, and lysozyme in dam's serum and milk were higher in high protein group. Total IgA and IgG in pup's serum remained higher in high protein group from 5 to 18 weeks of age. BLG-specific antibodies were found in the milk and serum of immunized dams, and in serum of pups born to immunized dams but not in the non-immunized group. BLG-specific IgA and IgG were again higher in high protein group and declined with time. The concentration decreased faster in the low proetein group than in the high protein groups. After immunization the pups with LBG, serum BLG-specific antibodies were not differ between rats born to immunized dams and those born to non-immunized dams. Therefore passive immunity rats received via milk as a pup had no effect on the BLG-specific antibody production later in life. This study shows the importance of protein status of mother and strongly support to the endorsement of breast feeding.

  • The purpose of this research was to investigate the effects of Seungyangikkitang (SIT) on the immune cells in BALB/c mice. SIT (500mg/kg) was administerd p.o. once a day for 7 days. SIT enhanced the proliferation of thymocytes, but decreased the proliferation of splenocytes. SIT enhanced the subpopulation of cytotoxic T cells in thymocytes and helper T cells in splenocytes, but did not affect the subpopulation of B220/Thy1 cells. SIT enhanced the production of γ-interferon and interleukin-2 in thymocytes, splenocytes and serum, but did not affect the production of interleukin-4. SIT suppressed the production of nitric oxide, but enhanced the lucigenin chemiluminescence and the engulfment of FITC-conjugated E. coli particles in peritoneal macrophages. These results suggest that SIT has a potent activity on the specific immunity via the cytokine secretion of Th1 cells and the non-specific immunity via the phagocytic activity of macrophages in vivo.

  • This study investigated the effects of dietary supplementation with Sargassum horneri celluclast hydrolysate (SHCH) on the growth performance, feed utilization, non-specific immunity and antioxidant capacity of the Pacific white shrimp Penaeus vannamei. Six diets were prepared by SHCH supplemention levels of 0, 5, 10, 20, 40 and 80 g/kg (designated as Con, S5, S10, S20, S40 and S80, respectively). A total of 540 shrimp were randomly distributed in triplicate across 18 tanks and fed one of the diets for five weeks. Weight gain did not differ significantly among the groups except for S80. The feed conversion ratio was significantly lower in S10 than in S80. Phenoloxidase and nitro-blue tetrazolium activities were significantly higher in S5 than in Con. The prophenoloxidase gene was significantly upregulated in S10 compared to that in Con. The gene expression of crustin, glutathione peroxidase, lipopolysaccharide and β-1,3-glucan-binding protein were significantly upregulated in S5 compared to Con. The superoxide dismutase gene was significantly upregulated in S20 and S80 compared to Con. Supplementing shrimp diets with up to 8% of SHCH did not impair non-specific immunity or antioxidant capacity. However, based on growth results, supplementation up to 4% was considered appropriate.

  • Effects of Korean mistletoe, Viscum album coloratum on the non-specific immune responses of Japanese flounder, Paralichthys olivaceus were examined. Flounder were inoculated with mistletoe, Freunds complete adjuvant (FCA), or phosphate-buffered saline (PBS) as a control into their peritoneal cavities. Reactive oxygen intermediate (ROI) products were more enhanced in mistletoe-injected fish kidney phagocytes than in FCA-injected ones. The level of lysozyme activity detected in the serum of fish 4 d after injection with mistletoe was also significantly higher than that found in the serum of the control fish. The appropriate concentration of mistletoe in eliciting the highest level of serum lysozyme activity was 500 $\mu$m/300 g of fish. In phagocytic activity assays, mistletoe-sen-sitized flounder kidney phagocytes captured more yeasts than those of the control fish. Korean mistletoe appeared to be a good activator of the non-specific immune responses of Japanese flounder.

  • 흰다리새우는 광범위한 염도(1-40 psu)에서 생존 가능하다. 하지만 염도의 변화, 특히 낮은 염도(1-5 psu)는 생존율, 비특이적 면역능 및 항병능과 같은 다양한 생리적 변화에 영향을 미칠 수 있다. 본 연구에서는 73일 동안 경구 투여 및 사육수 첨가를 동시에 수행한 뒤 성장, 비특이적 면역 및 질병 저항성을 측정하였다. 사육수의 염도는 주기적으로 소금을 첨가하여 3 psu를 유지하였다. 그 결과 73일간 사육 후 생존율이 크게 증가하였으며 (5.6 vs. 15.4%), reactive oxygen species (ROS) 생산과 phenol oxidase (PO) 활성의 유의성있는 증가가 확인되었다. 대조적으로 superoxide dismutase (SOD) 활성은 영향을 받지 않았다. 새우에서 Vibrio alginolyticus의 인위 감염 시험의 결과, 프로바이오틱스 처치구에서 약간의 폐사 감소가 관찰되었다(100 vs. 79%). 결과적으로 저염도(3 psu)에서 양식된 흰다리새우의 생산은 저염도에서 생존가능한 프로바이오틱스에 의해 증가 될 수 있을 것이다.

  • Shrimp has efficient non-specific defense mechanisms based on activities of the hemocytes against pathogens. Up to now, it has been known that one of the non-specific immune reactions is related to mutual association among types of hemocyte, granular cell, semi-granular cell, and hyaline cell. In this study, we tried to know the effectiveness of feed-additives such as 5-aminolevulinic acid(ALA), chitosan, and hot-water extract of herb on immunity of shrimp (Penaeus chinensis) by hemocytic observation and SDS-PAGE analysis. Finally, we suggest a principle of the examination system for effects of various feed-additives.

  • 알코올 중독자의 폐렴관리와 같은 건강관리에 필요한 비특이 면역력, 면역기능을 측정하기 위하여 알코올 중독 의존형으로 입원한 신,구환자군에 대하여 다음과 같은 결과를 얻었다. 대조군에 대한 알코올 중독증은 MCV, 혈당, $\gamma$GTP를 이용한 생물학적 측정 결과에 의하여 확인하였으며, 기타 측정 항목은 대조군과 유사한 결과를 나타내었다. 림프구 아형 분석 결과 대조군은 한국인 참고치와 매우 유사하였으며, 실험군 CD4+를 제외한 CD3+, CD8+, CD19+이 감소되었고, CD4+/CD8+비율은 통계적으로 유의하게 증가되어 있음을 알 수 있었다. 따라서 실험군의 면역기능과 림프구 증식능은 대조군에 비하여 현저하게 저하되었으며, 탐식세포 탐식능 및 유주능도 대조군에 비하여 현저하게 감소되었다. 탐식세포의 유주능과 CD4+의 증가, CD4+/CD8+비율의 증가와 PHA에 의한 림프구 증식능의 감소 및 CD3+, CD19+ 감소등은 상호관련성을 가지고 일치된 결과를 보여 대조군에 비하여 현저하게 저하된 탐식세포의 탐식기능과 함께 알코올 중독자의 비특이 면역계, 면역기능이 현저하게 저하되어 있음을 알 수 있었다. 그러나 알코올 중독 의존형으로 입원한 신,구환자간의 비교 분석 결과 총단백질, 혈색소, 림프구 증식능, 탐식세포 탐식능, 유주능에서 신환자군에 비하여 구환자군이 대조군에 다소 근접되어가는 결과로부터 치료에 따라 숙주의 세포성, 체액성 면역기능이 회복되어가고 있음을 알 수 있었다. 또한 결과 알코올중독자의 비특이적 면역능의 측정을 위한 탐식세포 탐식능, 유주능은 숙주, 미생물측의 활성화 자극인자가 모두 포함된 phagocytic plaque film법에 의하여 측정함이 의의 있는 평가를 할 수 있을 것으로 보며, CD4+/CD8+ 림프구 아형 비율을 이용한 면역기능의 측정은 알코올 중독자의 건강 관리를 위한 면역력 측정에 유용한 방법이라고 생각된다사이에서는 차이를 인정할 수 없었다. 그러나 25개월 운동군은 대조군에 비하여 유의한 차이로 감소하였다. 연령증가에 따른 사립체 내막 표면밀도와 사립체수는 대조군과 운동군 사이에는 유의한 변화는 없었다. 본 연구의 성적을 검토한 결과 젊은층(3개월군)과 중령층(10개월군)의 횐 쥐에서는 반복된 지구력운동이 심장에 미치는 역효과를 인정할 수 없었으며 젊은 층의 횐 쥐에서는 오히려 심장기능 강화를 보이는 경향이 나타났으며, 노화층(20개월군)에서 운동군에서는 스트레스로 작용하여 심장기능의 저하를 초래하였다고 생각된다.서 낭송된다. 그러나 이 연구의 기본은 시인과 독자의 율형(Metrical Pattern)에 대한 의식과 의도(intention)가 전제된다. 이것은 이 연구의 문제임과 동시에 장점이다. 시율의 분석은 보는 율형이 아니라 읽고 낭송하는 율형으로 분석되어야 함을 보여 준 것이 이 연구의 기여이다.ight reduction but the rapid weight gain was noticed right after the diets ceased.나 인과 질소 평형에는 큰 영향을 미치지 않았다.더덕은 20(種)이었다. 9.
