  • This study was performed to investigate the growth rate, hematological and serological changes of the rats when they were fed with the high fat diets supplemented with or without the tannic acid for five weeks. Thirty-two Sprague-Dawley male rats(235.7\pm10.7g\;of\;body\;weight)$ were randomly divided into four groups, control group and three treatment groups(T1, T2 and T3). Rats in control group were fed with the high fat diet containing $15\%\;lard,\;1\%$ cholesterol and $0.5\%$ sodium cholate(wt/wt) which was modified from the formula of American Institute of Nutrition (AIN)-76 diet and rats in treatment groups were fed with above diet supplemented with $0.25\%(T1),\;0.5\%(T2)$ or $0.75\%(T3)$ of tannic acid(wt/wt), respectively. The supplementation of tannic acid(TA) did not affect the final body weight, gain of body weight and feed intake of rats in both control and treatment groups. The numbers of red blood cells, hemoglobin concentrations and hematocrit values in blood of rats showed no significant differences between control group and treatment groups. The glucose concentration and albumin/globulin(A/G) ratio of rats in treatment groups were slightly lower than that of control group without significance. The values of total protein, albumin and globulin showed no significant differences between control group and treatment groups. The values of total cholesterol, low density lipoprotein­cholesterol and atherogenic index in sera of rats in treatment groups were much lower than that of control group without significance. The values of triglycerides in sera of rats in T3 group were significantly lower than that of control group (p<0.05). The values of AST and ALT in sera of rats in T3 group were significantly lower than that of control group (p<0.05). Thus supplementation of tannic acid to high fat diet could be effective to reduce the serum lipid levels such as total cholesterol, high density lipoprotein-cholesterol and triglycerides which were regarded as to cause the cardiovascular diseases.

  • 동면 상태에서 혈액성분의 생화학적 변화치를 조사하고자 전남 각지에 서식 또는 광주직할시 근교에서 양식하고 있는 뱀장어, 개구리, 살모사 그리고 다람쥐를 활동기(7월∼8월), 잠입기(10월∼11월), 동진기(12월∼1월) 및 각려기(3월∼4월)에 채집하였다. 이들 동물들의 혈청에서 Total protein, Albumin, Globulin, A/G ratio, Glucose, Calcium, Urea함유량을 조사하여 얻은 성적을 비교 검토하여 다음과 같은 결론을 얻었다. 1 . Total protein의 변화는 각 동물사이에서 상당한 차이를 보이되 잠입기에 다소 증가하였다. 특히 다람쥐에서 Total protein 함유량이 다른 동물들 보다 많았다. Albumin함유량은 잠입기에 상승하였고 동면기에는 약간의 감소를 보이다가 각성기에는 현저한 감소를 보였다. gloulin함유량은 잠입기에 상당히 상승하고 동면기에 약간의 감소를 나타내었으며 각성기 인 봄철에는 많은 증가 현상을 보였다. 2. 혈청 Urea의 함유량은 동면의 각과정에 따라 상당한 차이가 있었다. 즉 잠입기에 약간 상승하고 동면기에는 저하를 보였으며 각성기에는 전 실험동물에서 검출되지 않았다. 3. 혈당의 변화는 잠입기에 대체로 저하하고 동면기에는 심한 저혈당 수준에 이르렀다. 각성기인 봄철에는 다람쥐를 제외하고는 동면기의 혈희량과 유사하였다. 4. 혈청 Calcium함유량의 변화는 활동기에 비하여 잠입기에는 상당한 증가현상을 보였으나동면기에는 전 실험동물이 거의 같은 수준으로 감소를 보이며 각성기에 까지 감소하였다. In order to the biochemical change of the serological components of hibernating animals, eels(hnguillo joponica Temminck et Schlegel), frogs (Rana nigromacurata Hallowell), snakes (Agkistro-don holds breuicaudus Stejneserl, squirrels (Tamias striatus Linnaeus) which were collected around Gwangiu city and the Chunnam area were observed in accordance with the phases of hibernation. The author described the hibernating cycle as active (June-July), prehibematins(October-Novemberl, hibernating (December-January) and posthibemating phase (March-Aprill. The values of total protein, albumin, globulin, hJG ratlo, calcium, glucose and urea were chiefly investigated in their serum. The results are as following: Total protein was shown to be consider-able in eels, frogs, snakes, squirrels and increased in prehibemation. Especially, the mean value was high in sqirrels. Albumin values was increased during prehibemation. But a little decrease was shown during hibernating and an outstanding decrease during posthibemation. The globulin value increased considerably during prehlbemation but decreased a little during hibernation phase. Changes of urea were shown to be considerable according to the stage of each hibem3-tion. A little increase was shown during prehibemation and decrease during hibernating stage. but urea was not found in posthibemation in any experimental animals. The glucose value was generally decreased during prehibematlon. An extremely little increase in glucose was shown during hibernation (hypoglycemia). All hibernating values except those for squirrels in spring posthibemating phase were at almost the same level. The calcium value was shown to be considerable during prehibemation in comparison with active phase. The same level of decrease was represented in all kinds of animals and continued at the stage of posthibemation.

  • Objectives The purpose of this study is to find out the effect of various concentrations of Hwangnyeonhaedok-tang (HTT) pharmacopuncture on ST25 (天樞) in rats with dextran sulfate sodium (DSS)-induced colitis.Methods Colitis was experimentally induced by feeding rats with water mixed with 5% (w/v) DSS for 20 days. The rats were divided into 5 groups: the normal group (Nor, n=5), the control group - colitis induced rats with no treatment (Con, n=5), the acupuncture group - colitis induced rats with acupuncture applied on ST25 (Acu, n=5), the pharmacopuncture group 1 - colitis induced rats with 0.729 mg/250 g/40 μl of pharmacopuncture applied on ST25 (PA-1, n=5), the pharmacopuncture group 2 - colitis induced rats with 3.645 mg/250 g/40 μl of pharmacopuncture applied on ST25 (PA-2, n=5). The changes in weight, excrement concentration and hemafecia were observed 5 times every 2 days. The colon lengths were measured from appendix to the end of colon after the experiment. Hematological and serological exams were conducted the day after the last treatment by cardiac puncturing anesthetized rats.Results ST25 is the abdominal front point (募穴) of large intestine meridian and is known to have effect in colitis. Various concentrations of HTT pharmacopuncture (HTTP) applied on ST25, in rats with DSS-induced colitis inhibited decrease in colon lengths and body weight in both PA-1 and PA-2 groups. Hematological and serological exam results also showed that HTTP has significant effect on colitis in both PA-1 and PA-2 groups.Conclusions Colon lengths were significantly increased in the acupuncture group, PA-1 group and PA-2 group, compared to the control group. The body weight was significantly increased (p<0.05) in PA-2 group after the first treatment, compared to the control group. TNF-α, IL-6, AST were significantly decreased in PA-1 and PA-2 groups, compared to the control group.

  • 아니사키스중에서 조직병리학적 병변과 혈청학적 반응의 시간 경과에 따른 변동 양상을 관찰하고자 이 실험을 실시하였다. 조기 와 아나고 내 잔에서 구한 멸룬연상 type I 유충을 체중 3kg 내외의 집토끼에 30마리씩 경구 투여하고, 감염 전과 감염 후 3, 13, 20, 30, 60, 90, 150일에 채 늴하여 혈청을 냉동 보관 하였다. 동시에 13, 20, 30, 60, 90, 150일에 1~3마리 씩 도살하여 위부터 하행결장까지 육안으로 검사하여 아니사키스 충체의 유무를 조사하고, 충체가 감염된 부위를 선택하여 조직학적으로 관찰하였다. 또한 냉동 보관한 혈청을 이용한 micro-ELISA를 시행하여 항체가의 변동을 관찰하였다. 그 결과를 요약하면 다음과 같다. 1. 육안 검사에서 아니사키스 유충은 위에서 57.7%가 검출되고, 그 이외에 대망(mentum), 잗, 장간막, 복막등에서도 검출되 었다. 감염기 간에 따른 충체의 검출율이나 검출부위의 차이는 인정 할 수 없었다. 전체 충체검출율은 18.6%이고 살아서 움직이는 충체는 하나도 없었다. 2. 조직병리학적으로 관찰한 바, 감염 후 13일에는 대부분의 충체가 내부구조를 온전하게 유지하고 있으면서, 충체 주위에는 농양이 형성되어 있어 감염된 위장관벽이 2~3배 두꺼워져 있었다. 충체 주변에 섬유성 삼출액이 염증세포와 혼합되어 있고 그 주위를 조직세포(histiocytes)가 층을 이루며 둘러싸고 다시 주위의 병소 대부분을 수많은 염증세포(중성구, 호산구, 림프구등)와 섬유아세포가 차지하고 있었다. 감염 후 20일과 30일에는 삼출액이 차츰 줄고, 섬유소가 증식하는 육아조직으로 전환되었다. 충체는 20일 관찰된 것부터 괴사에 빠지고, 30일에는 조직구가 직접 충체를 둘러싸며 숙주세포가 충체를 침윤하는 것이 뚜렷이 관찰되었다. 또 30일부터 칼슘이 침착된 충체가 관찰되었다. 감염 후 90일과 150일에는 칼슘화된 충체만이 관찰되며 충체주위는 섬유조직으로 대체되고 소수의 염증세포 만이 모여 있었다. 3. ELISA를 이용하여 혈청내 Is G항체가의 측정결과 감염 후 기간에 따른 카 군별 흡광도(O.D.)의 평균(${\pm}표준편차$)치가 대조군 0.165(${\pm}0.144$), 3일 0.257(${\pm}0.194$), 13일 0.448(${\pm}0.257$), 20일 0.662(${\pm}0.311$), 30일 1.113(${\pm}0.336$), 60일 0.993(${\pm}0.331$), 90일 0.740(${\pm}0.185$), 150일에 0.376이 었다. 이상의 결과로 미루어 토끼에 감염된 아니사키스는 감염 1주 경에 죽고, 2주 정도 까지는 형태학적 구조를 유지하지만, 20일 이후에는 괴사되며, 30일 이후에는 숙주 세포에 의하여 파괴 흡수되거나 석회화되는 과정을 겪고, 90일 이후에는 석회화된 것 이외에는 거의 흡수되어 관찰되지 않는다고 할 수 있겠다. 충체가 감염된 후 죽어서 흡수되기 시작하는 30일 정도의 기간동안 집중적으로 충체의 항원이 방출되어 항체가가 위와 같은 변화양상을 보인다고 판단된다. 감염 150일에는 항체가가 뚜렷하게 감소한 상태이므로 감염 후 20~90일에는 ELISA가 유용한 혈청학적 진단법이 될 수 있을 것으로 보인다. 실제로 진단에 적용하기 위해서는 교차 반응등에 관하여 더 연구가 진행되어야 할 것이다.

  • 목 적 : 상기도 감염의 원인균 중 하나인 A군 연쇄구균에 대한 EM 내성율이 1998년 41.3%였고 이들의 T-혈청형은 T12, T4, T28로 구분된 균주가 EM에 내성을 보이는 경우가 많았다. 매우 높은 비율의 EM 내성 A군 연쇄구균의 비율이 2년 후 어떤 변화를 보이는가를 역학적 동태를 감시할 수 있는 T-단백질 혈청형과 항균제 감수성 검사를 시행하여 상기도 감염의 치료실패율을 감소시키고, 선별적 항균제 사용을 권유하고자 한다. 방 법 : 2000년 1월부터 2000년 12월까지 서울 및 경남지역에서 급성 인두편도염 및 성홍열 증상을 주소로 외래를 방문한 환자들로부터 경부배양검사를 시행하여 얻어진 162례의 A군 연쇄구균 균주를 대상으로 T단백 혈청학 검사와 항균제 감수성 검사를 시행하였다. 결 과 : 전체 162균주 중 가장 흔하게 분리된 균주는 T12(27.15%)였으며, 그 다음으로는 T1(25.16%), T4(12.58%) 순서로 분리되었다. 전체 162균주 중 성홍열로 진단된 환아에게서 배양된 균주는 25례로, 이번 조사에서는 경남지역에 국한된 결과이지만 T형 분류는 T12, T1, T4의 순서로 분리되었다. 항생제 감수성 검사에서는 Tetracyclin에 내성을 보이는 균주는 25주로(15.4%) 이중 T12균주가 14주로(56%) 내성균주 중 가장 많은 분포를 보였으며, EM에 내성을 보이는 균주는 23주로(14.2%) 이중 T12균주가 11균주로 가장 높은 내성율을 보이는 균주로 조사되었다. Penicillin, Cefprozil, Vancomycin, Ceftriaxone, Chloramphenicol의 항생제에는 내성을 보이는 균주가 동정되지 않았다. 결 론 : 균이 배양된 지역적 장소가 동일하지는 않지만, 90년대 비교적 낮은 분포를 보였던 T12균주가 98년경부터 증가하는 양상을 보이더니 금번 조사에서도 가장 많이 분리되는 균주로 보고되었고, 또한 T12, T4균주는 항생제에 내성을 보이는 균주로 향후 분자 역학적인 검사로 이 세균의 역학적 토대 및 질병 발생과의 관계를 확인할 필요가 있을 것으로 사료되며, 항생제 선택에 있어서도 상기 내성균주에 대한 고려가 있어야 하겠다. 서울 전체지역과 경남지역의 혈청학 분포가 동일하므로 아마도 우리나라 전지역에서 배양되는 균주도 동일할 것으로 추측할 수도 있을 것이다.

  • A series of studies were carried out to investigate the supplemental effects of dietary garlic extracts (GE) on whole body amino acids, whole body and muscle free amino acids, fatty acid composition and blood plasma changes in 6 month old juvenile sterlet sturgeon (Acipenser ruthenus). In the first experiment, fish with an average body weight of 59.6 g were randomly allotted to each of 10 tanks (two groups of five replicates, 20 fish/tank) and fed diets with (0.5%) or without (control) GE respectively, at the level of 2% of fish body weight per day for 5 wks. Whole body amino acid composition between the GE and control groups were not different (p>0.05). Among free amino acids in muscle, L-glutamic acid, L-alanine, L-valine, L-leucine and L-phenylalanine were significantly (p<0.05) higher in GE than in control. However, total whole body free amino acids were significantly lower in GE than in control (p<0.05). GE group showed higher EPA (C22:6n3) and DHA (C22:5n3) in their whole body than the other group (p<0.05). In the second experiment, the effects of dietary garlic extracts on blood plasma changes were investigated using 6 month old juvenile sterlet sturgeon averaging 56.5 g. Fish were randomly allotted to each of 2 tanks (300 fish/tank) and fed diets with (0.5%) or without (control) GE respectively, at the rate of 2% of body weight per day for 23 d. At the end of the feeding trial, blood was taken from the tail vein (n = 5, per group) at 1, 12, and 24 h after feeding, respectively. Blood plasma glucose, insulin and the other serological characteristics were also measured to assess postprandial status of the fish. Plasma glucose concentrations (mg/dl) between two groups (GE vs control) were significantly (p< 0.05) different at 1 (50.8 vs 62.4) and 24 h (57.6 vs 73.6) after feeding, respectively, while no significant difference (p>0.05) were noticed at 12 h (74.6 vs 73.0). Plasma insulin concentrations (${\mu}IU$/ml) between the two groups were significantly (p<0.05) different at 1 (10.56 vs 5.06) and 24 h (32.56 vs 2.96) after feeding. The present results suggested that dietary garlic extracts could increase dietary glucose utilization through the insulin secretion, which result in improved fish body quality and feed utilization by juvenile sterlet sturgeon.

  • Fascioliasis is a foodborne zoonotic parasitic disease. We report 4 cases occurring in the same family, in whom diagnosis of acute fascioliasis was established after series of tests. One case was hospitalized with fever, eosinophilia, and hepatic lesions. MRI showed hypodense changes in both liver lobes. The remaining 3 cases presented with the symptom of stomachache only. Stool analysis was positive for Fasciola eggs in 2 adult patients. The immunological test and molecular identification of eggs were confirmed at the National Institute of Parasitic Diseases, Chinese Center for Disease Control and Prevention, Shanghai, China. The results of serological detection were positive in all the 4 patients. DNA sequencing of PCR products of the eggs demonstrated 100% homology with ITS and cox1 of Fasciola hepatica. The conditions of the patients were not improved by broad-spectrum anti-parasitic drugs until administration of triclabendazole.

  • Objectives: The present study was conducted to examine whether Haedoksamul-tang (HS), a traditional oriental herbal medicine, have beneficail effects on anti-inflammation and dyslipidemia in lipopolysaccharide (LPS)-induced ICR mouse. Methods: Twenty four 8-week old male ICR mouse were divided into four groups: normal untreated; LPS treatment only; HS 10 mg/kg plus LPS treatment; and HS 30 mg/kg plus LPS treatment. HS was orally administered per day for 2days. Twenty-four hours after LPS injection (10 mg/kg/day, i.p.), all the mice were sacrificed, and serological changes were evaluated. The levels of nuclear factor-${\kappa}B$ (NF-${\kappa}B$), sterol regulatory element-binding transcription protein 1 (SREBP-1) activity and cyclooxygenase-2 (COX-2), inducible nitric oxide synthase (iNOS), tumor necrosis factor a (TNF-a), monocyte chemotactic protein 1 (MCP-1), acetyl-CoA carboxylase a (ACCa) expression were analyzed in Western blot analysis. Results: HS inhibited oxidative stress in the liver of LPS-induced ICR mice. The LPS-induced ICR mice exhibited the increase of NF-${\kappa}B$ activity and COX-2, iNOS, TNF-a, MCP-1 expressions in the liver, while HS treatment significantly inhibited them. Moreover, The administration of HS significantly decreased the elevated serum triglyceride and down-regulated the levels of SREBP-1, ACCa in the liver of LPS-induced ICR mice. Conclusions: In conclusion, HS could have hepato-protective effects against the oxidative stress-related inflammation and abnormal lipid metabolism.

  • Objectives : Hoechunyanggyeok-san (HYS) is a traditional herbal medicine, which has been clinically used for treating febrile and inflammatory diseases. HYS has been reported to be a useful treatment for diabetes, atherosclerosis and hyperlipidemia in the type 1 diabetic model. However, the mechanism of the effects of HYS against hyperglycemia and hyperlipidemia is poorly understood. In the present study, we investigated the underlying mechanism of ameliorative effect of HYS on hyperglycemia and hyperlipidemia in vivo. Methods : HYS (10, 50 mg/kg/day, p.o.) was administered every day for 2 weeks to db/db mice and its effect was compared with vehicle-treated db/db mice. To confirm serum glucose and triglyceride (TG) changes, serological testing was performed. The levels of sterol regulatory element-binding protein-1 (SREBP-1) activity and Sirtuin1 (SIRT1), AMP-activated protein kinase (AMPK), and acetyl-CoA carboxylase ${\alpha}$ ($ACC{\alpha}$) expression were analyzed by western blot analysis. Results : The administration of HYS significantly decreased the elevated serum glucose and TG in db/db mice. HYS administration increased the levels of SIRT1 and AMPK expression compared with the vehicle-treated group. Moreover, HYS treatment significantly inhibited SREBP-1 activity and $ACC{\alpha}$ expression in the liver, while the vehicle-treated group exhibited their increase. Conclusions : In conclusion, HYS is suggested to have an improvement effect on hyperglycemia and hyperlipidemia by activating the SIRT1/AMPK signaling pathway and inhibiting SREBP-1.
