  • Cadmium (Cd) and tributyltin (TBT) are common contaminants of marine and freshwater ecosystems, and can induce the formation of reactive oxygen species (ROS). These ROS can, in turn, cause oxidative stress. In the present study, we investigated time-related effects of Cd (0.05 and 0.1 ppm) and TBT (5 and 10 ppb) treatment on antioxidant enzyme activity, i.e., the activity of superoxide dismutase (SOD) and catalase (CAT) in the gills and digestive glands of the ark shell, Scapharca broughtonii. In addition, hydrogen peroxide ($H_2O_2$) concentrations, lysozyme activity, and glutamate oxaloacetate transaminase (GOT) and glutamate pyruvate transaminase (GPT) levels were measured in the hemolymph. We found that Cd and TBT treatment significantly increased antioxidant enzyme mRNA expression and activity in the digestive glands and gills in a time-dependent manner. In response to the Cd and TBT treatments, antioxidant enzymes mRNA expression and activity increased up to day 5 in the digestive glands and then decreased by day 7. In the gills, antioxidant enzymes mRNA expression and activity increased up to day 3 and then decreased by day 5. Likewise, $H_2O_2$ concentrations significantly increased up to day 5 and then decreased by day 7. Finally, lysozyme activity decreased during the experimental period, whereas GOT and GPT levels were significantly increased in a time-dependent manner. These results suggest that antioxidant enzymes play an important role in decreasing ROS levels and oxidative stress in ark shells exposed to Cd and TBT.

  • Angelicae gigantis Radix aqua-acupuncture solution (AGRAS) and Angelicae gigantis Radix water-extracted solution (AGRWS) were prepared and tested for their organ toxicities and chemopreventive potentials. The organ-toxicity of AGRAS to male ICR mice was studied by the measurements of glutamic oxaloacetic transaminase (GOT), glutamic pyruvate transaminase (GPT), lactate dehydrogenase (LDH) and alkaline phosphatase (ALP-s) activities after injection of AGRAS for 7 days. The activities of GOT GPT and LDH were decreased, but the activity of ALP-s was not changed with AGRAS. When AGRAS was administered once daily for 10 days before the tumor implantation, AGRAS exerted antitumor activity by inhibiting the growth of Ehrich ascites tumor cells (EATC) in viva. The inductions of quinone reductase (QR), glutathione (GSH) and glutathione S-transferase (GST) and inhibition of polyamine metabolism were tested for the chemopreventive potentials of AGRAS and AGRWS. AGRAS was potent inducer of QR activity in murine hepatoma Hepalclc7 cells. In cultured rat Ac2F cells, AGRAS was also significantly induced QR activity GSH levels were increased about 1.3 fold with AGRAS. In addition the activity of GST was increased about 2.5 fold with AGRAS at the concentration of $0.1{\;}{\times}{\;}$. The effects of AGRAS and AGRWS were tested on the growth of Acanthamoeba castellanii. Proliferation of Acanthamoeba castellanii in a broth medium was inhibited by AGRAS and AGRWS at the concentration of $1{\;}{\times}{\;}and{\;}5{\;}{\times}{\;}$, respectively: These results suggest that AGRAS has chemopreventive potential by inducing QR activity increasing GSH and GST levels and inhibition of polyamine metabolism.

  • To investigate the effects of hot water soluble extract from Angelicae Gigantis Radix on lipid metabolism and antioxidant defense system in rats fed hypercholesterol diet, Sprague-Dawley male rats were fed either hypercholesterol diet with water or hot water soluble extract from Angelicae Gigantis Radix. Hypercholesterol diet contained 18 % beeftallow and 5 % cholesterol. After 4 weeks of experimental periods serum and liver obtained. The level of serum lipid and the activities of GOT and GPT was measured. The level of lipid and TBARS and the activity of GSH-Px was measured also. The results obtained were: 1) Food intake in the experimental group supplied hot water soluble extract from Angelicae Gigantis Radix was low significantly. 2) In the experimental group supplied hot water soluble extract from Angelicae Gigantis Radix of serum total lipid and total cholesterol was significantly low. 3) Serum GOT activity was significantly low in the experimental group supplied hotwater soluble extract from Angelicae Gigantis Radix. There was no difference of serum GPT activity between control and experimental group supplied hot water soluble extract from angelical Gigantis Radix. 4) There was no difference of lipid composition, TBARS level and GSH-px activity in liver between control and experimental group. The result of this study indicates that the hot water soluble extract from Angelicae Gigantis Radix was effective in decreasing the food intake of the experimental animals in the hypercholesterol diet and also effective in decreasing the levels of serum total lipid, total cholesterol and GOT activity. However it was not effective to change the level of lipid, TBARS and GSH-Px activity of liver.

  • In order to investigate the protective effects of Jiyusaenggan-Tang by F-I(Jiyusaenggan-Tang aspirated by distilled water), F-II(Non-polysaccharides in Jiyusaenggan-Tang) and F-III(Polysaccharides in Jiyusaenggan-Tang), experimental studies were performed in mice with liver injury induced by $CCI_4$, and d-galactosamine. The results were summarized as follows : 1. The increases of the serum GOT activities in mice induced by $CCI_4$ were inhibited significantly by the administration of highly concentrated FIII. The increases of the serum GPT, LDH, and ALP activities in mice induced by $CCI_4$ were inhibited significantly by the administration of highly concentrated FI and FIII. 2. The increases of the serum total-cholesterol and triglyceride activities in mice induced by $CCI_4$ were inhibited significantly by the administration of highly concentrated FI, FII and FIII. 3. On liver injury induced by the $CCI_4$, the activities of GOT, GPT, ALP, LDH were inhibited by highly concentrated FIII, F-I, F-II, and F-I, F-II, F-III on total cholesterol level and F-III, F-I, F-II on triglyceride level in order of their efficacies. And F-III is considered to be the most effective component. 4. The increases of the serum GOT, GPT activities in mice induced by d-galactosamine were inhibited significantly by the administration of FI and FIII. The increases of the serum LDH, ALP activities in mice induced by d-galactosamine were inhibited significantly by the administration of FI and FIII. 5. The increases of the serum Total-cholesterol, Triglyceride activities in mice induced by d-galactosamine were inhibited significantly by the administration of FI, FII and FIII. 6. The increases of the serum GOT, GPT activities in mice induced by d-galactosamine were inhibited significantly in F-III administrated group and then F-I in order of efficacies. FII does not showed significant effect, on inhibiting the activities of serum GOT and GPT levels. The activity of ALP was inhibited by F-III, F-I, F-II, LDH by F-III, F-I in order of efficacies, and F-II did not showed significant effect on LDH activity. The triglyceride level was decreased significantly by F-III, F-II, F-I and the total cholesterol level by F-II, F-I, F-III in order of their efficacies. Judging from the above results, it is considered that Jiyusaenggan-Tang has protective effect against liver injury, and that Polysaccharides in Jiyusaenggan-Tang is more effective.

  • 국내에서 선별 육종된 불로 구기자의 처리방법에 따른 간기능 보호효과를 측정하기 위하여 사염화탄소$(CCl_4)$ 투여로 급성 간독성을 유발시킨 흰쥐를 대상으로 연구하였다. 건조구기자 추출물(DFE), 볶은 구기자 추출물 (RFE), 그리고 생과즙(FFE)을 경구 투여한 결과 군간의 체중증가량은 차이를 나타내지 않았다. 한편, 체중 100 g 당 간 무게는 처리조건에 관계없이 구기자 추출물 및 생과즙 투여군이 유의적으로 낮은 간 무게를 나타내었다(p<0.01). 이것은 구기자 추출물과 생과즙 섭취가 $CCl_4$ 투여에 의한 지방간 형성 또는 간 독성에 의한 간 무게증가를 다소 완화하여준 효과를 나타내는 것으로 판단된다. 사염화탄소$(CCl_4)$ 투여에 의하여 흰쥐의 혈청 GPT 및 GOT 활성과 LDH 활성은 유의적으로 증가하였으나 볶은 구기자 추출물 투여군(RFEC)과 생과즙 투여군(FFJC) 모두 GPT, GOT 활성이 유의적으로 감소되었다. 혈중 총 콜레스테롤 함량은 구기자 추출물과 생과즙 투여군 모두 대조군(CON)과 비교하여 유의적인 증가를 나타내지 않았고 중성 지방함량은 대조군에 비해 유의적인 증가를 나타내었다(p<0.05). 간 조직의 MDA 함량과 GST, cytochrome P-450 활성 결과로 보아 구기자 추출물과 생과즙을 섭취 시 사염화탄소에 의한 독성을 완화시키는 것으로 나타났다. 따라서 이러한 모든 결과를 종합해 볼 때, 구기자 추출물과 생과즙은 $CCl_4$ 투여로 인한 지질 과산화, 지방변성, 간 세포 괴사 등을 억제 시키는 간 독성 보호 효과가 있는 것으로 생각된다.

  • 생균(Bacillus polyfermenticus, Bacillus mesentericus, Streptococcus faecalis, Bifidobacterium breve)과 소화 요소(protease, lipase)를 함유한 비스루트의 효과를 알아보기 위해 사료 내 1% 첨가하여 나일틸라피아 치어(19.0${\pm}$0.07g)에게 60일간 공급한 다음 성장률, 체조성 및 면역반응의 효과를 조사하였다. 60일간 사육한 결과 비스루트 첨가구와 대조구 사이에 유의적인 성장 차이를 보이지 않았지만(P>0.05), 보체의 용혈 능력은 비스루트 첨가구가 대조구에 비해 용혈능이 높은 것으로 조사되고 라이소자임의 용균 효과는 대조구와 비슷하였다. 식세포의 식작용 능력과 신장 마크로파지의 respiratory burst activity 는 비스루트 첨가구가 대조구에 비해 활성이 매우 높았다. 따라서 비스루트 사료 내 첨가가, 어류의 비특이적 면역 기능중에서 세포성 면역 기능을 활성화하는데 기여하였다. 병원성 세균 Edwardsiella tarda FSW 910410 균주로 공격 실험결과 비스루트 첨가구가 누적폐사율이 59%, 대조구가 80%로 조사되었고, 그 결과 비스루트 첨가구는 병원성 세균에 대한 저항력을 증가시켰다(P<0.05). Hematocrit, hemoglobin, total protein, glucose, GOT, GPT 와 같은 혈액 성분을 분석한 결과 비스루트 첨가구와 대조구 간의 유의차는 없었지만(P>0.05), glucose, GOT, GPT는 비스루트 첨가구가 대조구에 비해 낮게 나타났다. 이상의 결과로 비스루트는 나일틸라피아의 생리 기능에 문제를 야기시키지 않고, 비특이적 면역 기능 중 세포성 면역 기능을 증강시키는 효과가 있으며, 병원성 세균에 대한 저항력의 증강 효과도 높다. 따라서, 비스루트는 나일틸라피아의 사료 첨가물로서의 역할이 충분히 기대된다.
