Objective: In this study, the effects of saffron stigma against subacute diazinon (DZN) toxicity on enzymes levels, biochemical, hematological, histopathological and genotoxicity indices were studied in rats. Methods: Vitamin E (200 IU/kg) and the aqueous extract of saffron (50, 100 and 200 mg/kg) were injected intraperitoneally three times per week alone or with DZN (20 mg/kg/day, orally) for 4 weeks. The hematological and biochemical parameters were evaluated at the end of 4 weeks. Results: Reticulocytes counts, alkaline phosphatase (ALP), aspartate aminotransferase (AST), alanine aminotransferase (ALT), lactate dehydrogenase (LDH), creatine phosphokinase, CPK-MB, gama glutamyl transferase (GGT), uric acid and micronucleus indices were increased significantly but total protein and RBC cholinesterase activity were decreased in the DZN-treated group. Saffron prevented the effect of DZN on GGT (50 mg/kg), LDH, CPK and CPK-MB (100 and 200 mg/kg) levels. An increased uric acid and reduced protein levels by DZN were prevented by vitamin E and some doses of saffron. A significant reduction was observed in platelets, RBC, hemoglobin and hematocrit indices in the DZN group. Saffron and vitamin E prevented this reduction. Vitamin E and saffron did not reduce the effect of DZN on RBC cholinesterase activity. The extract and vitamin E could not prevent DZN genotoxicity in the micronucleus assay. Other biochemical parameters and pathological evaluation did not show any abnormality in tissues of all groups. Conclusion: This study shows that vitamin E and saffron reduce DZN induced hematological and biochemical toxicity. However, they do not prevent the genotoxicity induced by DZN.

본 실험은 식이중에 첨가된 coenzyme Q10이 adriamycin (ADR)을 투여한 흰쥐의 심근 미세 구조에 미치는 영향을 규명하기 위하여 실시되었다. 실험군은 모두 ADR 2수준(1.0mg/kg B.W./week, 2.0mg/kg B.W./week)과 coenzyme Q10 3수준(무첨가군, 0.1g / kg diet 및 0.5g / kg diet)에 의한 6개의 실험군과 basal diet만을 공급하는 대조군을 설정하였다. 체중증가량은 ADR의 투여수준이 높을수록 유의적으로 감소되었으며 식이효율에 있어서는 고수준의 ADR 투여시에만 대조군에 비하여 감소되었다. 그러나 coenzyme Q10에 의한 회복효과는 나타나지 않았다. 혈장내 CPK 활성도는 ADR투여로 약간 증가되었으나 유의적인 차이는 없었으며 coenzyme Q10 급여에 대한 영향은 나타나지 않았다. 전자현미경을 통해 심장조직의 형태적변화를 살펴본 결과 ADR투여로 인해 심근세포내 미세구조의 변성을 관찰할 수 있었고 특히 mitochondria 의 변형, myofibil을 비롯한 세포 소기관의 소실 및 파괴로 빈 공간이 형성되어 있었으나 coenzyme Q10 급여군에서는 그 정도가 약화되었다. 고수준의 ADR 투여는 mitochondria 의 volume density와 surface density를 크게 감소시켰지만 고수준의 coenzyme Q10 급여에 의해 이러한 감소가 조절되었다.

The objective was to devise an animal model of myocardial infarction (MI) against which cardioprotective drugs might be tested. We describe the effects of nimesulide, a COX experience with development and validation of such a model. The rabbit was chosen in preference to rodents because its heart and cardiac circulation more closely resemble those of human. Thus, the cardiovascular system of anaesthetized male rabbits, 1 to 1.5 kg (n=11), was stressed by a single bolus intravenous injection of isoprenaline (ISP), 65 mg/kg. The effects of the injection were followed for sixteen days and were evaluated in four ways: 1) measurements of creatinine kinase isozyme and troponin-I (TPI) in serum 2) Electrocardiographic (ECG) changes (ST elevation and Q wave development) 3) Cardiac histopathology observed in tissue sections of the isolated of the heart. The histopathological analysis showed that rabbit heart on 2nd day after ISP injection showed changes of coagulation necrosis. Day 4 total coagulation with the loss of nuclear and striation associated with heavy interstitial infiltrate of neutrophils was found. Day 8 after infarction showed collagen deposition with capillary channels in between the remaining islands of myocytes in the infarcted area. On the 16th day scarring was complete. Coronary perfusion rates (CPR) and heart rate (HR) of the infarcted and nimesulide (a COX-2 inhibitor) treated rabbits displayed significant improvement (n=11) on each corresponding day after infarction as compared to the infarcted and saline treated rabbits (P<0.05). All four indices revealed similarities with effects commonly associated with MI in humans.

Objectives: This study examined the effects of salvianolic acid B (SAB) on exhaustive exercise-induced cardiac muscle damage to rats. Methods: The study was carried out with 12-week-old young adult male Sprague-Dawley rats. Thirty-six rats were divided into 3 groups; normal (n=12), exhaustive exercise group (ExS, n=12) and exhaustive exercise with SAB (ExS+SAB, n=12). Five days before exhaustive exercise, SAB were medicated for 5 days in ExS+SAB group. Rats in ExS and ExS+SAB group were forced to swim for 150 minutes and then they were sacrificed, while rats in normal group were sacrificed at rest. After that, blood was collected and cardiac muscle tissue damage indices were analyzed. Results: Serum aspartate transaminase activity and lactate dehydrogenase activity were significantly lower in ExS+SAB group than in ExS group. Serum creatine phosphokinase activity of ExS+SAB was significantly lower than ExS group. However, the content of serum creatinine had no difference between ExS and ExS+SAB group. In the H&E stained left ventricle myocardium, ExS group showed signs of myocardial damage such as sporadic fragmentation of myocardial fibers, interstitial edema, cytoplasmic eosinophilia and neutrophils infiltration. However, ExS+SAB group alleviated the severity of the signs of myocardial damage. In the myocardial dihydroethidium staining, optical density was remarkably decreased in ExS+SAB group compared to ExS group. Furthermore, the up-regulation of Bax/Bcl-2 ratio was observed in ExS+SAB group compared with ExS group. Conclusions: The above results suggest that SAB may protect cardiac muscle damage via antioxidant activity and prevention of apoptosis.

Objective: Chicken essence and branched chain amino acid (BCAA) supplementation has been recognized to significantly relieve fatigue. To obtain chicken essence with high amounts of BCAA, spent hens herein was used to prepare dripped chicken essence (SCE) and compared with commercial dripped chicken essence (CCE) for in vivo anti-fatigue effect. Methods: To determine the effect on anti-fatigue by dripped chicken essence, the exhaustive swimming was performed. Thirty-two 7-week ICR mice were divided into four groups, which included the control group (CG), CCE, SCE-1X and SCE-2X. The mice were given daily oral administration (0.012 mL/g body weight/d). The fatigue index analysis was conducted weekly. Results: The results showed that SCE had a higher BCAA level as expected, and mice treated with dripped chicken essence (CCE and SCE) could significantly improve exercise performance. The lower blood lactate level, blood urea nitrogen level and creatine phosphokinase activity were found in the supplement of SCE group compared with the CCE group, which suggested that the SCE possessed strong anti-fatigue ability. This could possibly be due to the higher content of BCAA. Conclusion: In this study, SCE promoted recovery from physical fatigue in mice and elevated endurance ability. Among them, the double dose (SCE-2X) showed the strongest anti-fatigue ability. Taken together, spent chickens could be a good source of chicken essence to improve the effect of anti-fatigue.

Background: Hypothermia is a crucial environmental factor that elevates the risk of cardiovascular disease, but the underlying effect is unclear. Objectives: This study examined the role of cold stress (CS) in cardiac injury and its underlying mechanisms. Methods: In this study, a chronic CS-induced myocardial injury model was used; mice were subjected to chronic CS (4℃) for three hours per day for three weeks. Results: CS could result in myocardial injury by inducing the levels of heat shock proteins 70 (HSP70), enhancing the generation of creatine phosphokinase-isoenzyme (CKMB) and malondialdehyde (MDA), increasing the contents of tumor necrosis factor-α (TNF-α), high mobility group box 1 (HMGB1) interleukin1b (IL-1β), IL-18, IL-6, and triggering the depletion of superoxide dismutase (SOD), catalase (CAT), and glutathione (GSH). Multiple signaling pathways were activated by cold exposure, including pyroptosis-associated NOD-like receptor 3 (NLRP3)-regulated caspase-1-dependent/Gasdermin D (GSDMD), inflammation-related toll-like receptor 4 (TLR4)/myeloid differentiation factor 88 (MyD88)-mediated nuclear factor kappa B (NF-κB), and mitogen-activated protein kinase (MAPK), as well as oxidative stressinvolved thioredoxin-1/thioredoxin-interacting protein (Txnip) signaling pathways, which play a pivotal role in myocardial injury resulting from hypothermia. Conclusions: These findings provide new insights into the increased risk of cardiovascular disease at extremely low temperatures.

저산소 심근의 산소 재공급시에 보이는 심근 손상(oxygen paradox) 기전을 규명하고, 이의 예방법을 찾기 위한 연구의 일환으로 유독성 산소 대사물인 산소 라디칼의 관련성과 지질과산화활성화 및 항산화제의 심근 보호 효과를 검토하였다. 흰쥐 적출 심장을 Langendorff 심장관류법 으로 산소 및 glucose 공급을 중단한 cardioplegic 용액으로 관류 ($37^{\circ}C$, 90분)하여 저산소 상태를 만든 후, 계속해서 산소재공급 관류(20분)를 시행하여 저산소-산소 재공급 심근 손상을 유도 하였다. 심근 손상의 지표로 creatine phosphokinase(CPK), lactic dehydrogenase(LDH)의 관상관류액으로의 유출을, 그리고 지질과산화 척도로는malondialdehyde(MDA) 생성을 측정하였으며, 이에 대한 산소 라디칼 제거물질과 항산화제 ${\alpha}-tocopherol$ 및 butylated hydroxytoluene(BHT)의 효과를 검토하여 다음과 같은 성적을 얻었다. 1. 세포질 효소인 CPK 및 LDH의 유출과 지질과산화산물의 하나인 MDA의 생성은 산소 재공급과 더불어 급격히 증가하였다. 2. 산소 재공급시 세포질 효소의 유출과 MDA 생성은 높은 상관관계를 보였다. 3. Superoxide anion$(O_2)$의 제거 호소인 superoxide dismutase (10,000U), $H_2O_2$ 제거 효소인 catalase (25,000 U) 그리고 hydroxyl radical (OH) 제 거 물질인 dimethylsufoxide(10%)는 세포질 효소의 유출 증가와 MDA 생성 증가를 현저히 억제하였다. 4. 생리적 항산화물질인 ${\alpha}-tocopherol$.of (4.5 uM)과 합성 항산화제인 butylated hydroxytoluene(2 uM)은 산소 공급에 따른 MDA 생성 증가와 세포질 효소의 유출 증가를 용량의존적으로 억제하였다. 5. 항산화제들의 심근 보호 효과는 산소 재공급시 투여할 때보다는 저산소 관류시부터 투여한 경우에 더욱 현저하였다. 이상의 결과에서 저산소 심근의 산소 재공급은 유독성 산소 대사물인 산소 라디칼의 생성을 증가시키며, 그에 따른 지질성분의 과산화가 심근 손상을 일으키는데 관여할 것으로 여겨졌으며, 저산소-산소 재공급 심근 손상은 지질과산화 반응을 억제하는 항산화제에 의하여 방지될 것으로 사료되었다.

Streptozotocin(STZ 55 mg/kg BW., I.P. injection)으로 유발된 당뇨성 Sprague Dawley계 수컷 흰쥐에 있어서, 삼백초 생리활성물질 추출액(3.5 g% extract)의 섭취에 의한 혈당, 전해질, 혈청 지질개선효과 및 당질대사 이상 등에 관여하는 효소의 활성 변동을 생리생화학적 측면에서 검토하기 위하여 본 실험을 수행하였다. 기본식이만을 급여한 대조군인 Normal군을 비롯한 STZ 당뇨 유발군(NSW군), 당뇨 유발에 삼백초 잎 추출액을 섭취시킨 군(NSSL군) 및 당뇨 유발에 삼백초 뿌리 추출액을 섭취시킨 군(NSSR군)을 5주간 실험 사육하였다. 혈당 농도는 당뇨 유발군에 삼백초 추출액을 급여하므로서 유의적으로 저하됨을 관찰할 수가 있었다. 또한 혈청 총 콜레스테롤, 동맥경화지수, LDL, LDL- 콜레스테롤, 유리 콜레스테롤, 콜레스테롤 에스테르 비, 중성지방 및 인지질 농도 등은 삼백초 추출액을 섭취시킨 군(NSSL군, NSSR군)에서 농도가 유의성 있게 감소되는 것으로 나타났다. 한편, HDL-콜레스테롤 및 총 콜레스테롤에 대한 HDL-콜레스테롤 비 등은 삼백초 추출액 섭취(NSSL군, NSSR군)에 의해서 유의성 있게 증가 되는 것으로 나타났다. 혈청 중의 전해질(Na, K, Cl) 및 creatinine 농도는 STZ으로 당뇨 유발군에 삼백초 추출액을 섭취시킴으로서 유의성 있는 농도 저하 효과를 보였다. 또한, 혈청 중 aminotransferase(AST, ALT), creatine phosphokinase(CPK), lactate dehydrogenase(LDH) 및 alkaline phosphatase(ALP)의 활성은 STZ으로 당뇨 유발 시킨 후 삼백초 추출액을 섭취시킴으로서 저하되는 것으로 나타났다. 한편, 삼백초 잎(NSSL군)과 뿌리(NSSR군) 추출액 섭취에 따른 혈당, 각 종 지질 성분 및 효소 활성치의 두 군 간의 비교는 삼백초 잎이 뿌리 추출액에 비하여 다소 효과적인 차이를 보였으나 유의성 있는 변화는 보이지 않았다. 이상과 같은 결과들을 미루어 볼 때, 삼백초 중의 생리활성물질이 STZ으로 유발된 당뇨성 흰쥐의 혈당 조절 기능이상 및 혈청 지질대사 이상 등에서 오는 각종 질환의 예방 및 개선 작용에 효과가 있을 것으로 생각된다.
