Jicang Wang, Huali Zhu, Xuezhong Liu, Zongping Liu, 대한수의학회 Journal of Veterinary Science 9 Pages

Cadmium (Cd) is a well-known hepatotoxic environmental pollutant. We used rat hepatocytes as a model to study oxidative damage induced by Cd, effects on the antioxidant systems, and the role of N-acetylcysteine (NAC) in protecting cells against Cd toxicity. Hepatocytes were incubated for 12 and 24 h with Cd (2.5, 5, 10 μM). Results showed that Cd can induce cytotoxicity: 10 μM resulted in 36.2% mortality after 12 h and 47.8% after 24 h. Lactate dehydrogenase, aspartate... -

Toxic effects of ozone, 4-(N-methyl-N-nitrosamino)-1-(3- pyridyl)-1-butanone (NNK), and/or dibutyl phthalate (DBP) were examined through NF-kB, AP-1, Nrf2, and osteopontin (OPN) in lungs and livers of B6C3F1 mice. Electrophoretic mobility shift assay (EMSA) indicated that mice treated with combination of toxicants induced high NF-kB activities. Expression levels of p105, p65, and p50 proteins increased in all treated mice, whereas IkB activity was inhibited in NNK-, DBP-, and combination-treated... -
Ethanol Prevents from Acetaminophen Inducible Hepatic Necrosis by Inhibiting its Metabolic Activation in Mice
Sun-MeeLee, Tai-SoonCho, Young-NamCha 대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 9 Pages
대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 1998, Vol.2 No.2 15 261-269 (9 pages)
Concomitant administration of a single acute dose of ethanol (4 g/kg) protected mice from the hepatocellular injury observed upon administration of a large dose of acetaminophen (400 mg/kg). This was evidenced by the normal histological appearances of liver sections and by the lowered serum aminotransferase activities in mice treated with ethanol and acetaminophen together. In the mice treated with acetaminophen alone, along with the hepatic necrosis, the hepatic microsomal aminopyrine... -

이상일(Sang-Il Lee), 윤종국(Chong-Guk Yoon), 허근(Keun Huh) 대한약리학회 대한약리학잡지 8 Pages
대한약리학회 대한약리학잡지 1990, 제 26권 제 2호 11 185-192 (8 pages)
Diallyl disulfide의 간손상 예방효과를 검토할 목적으로 mouse에 bromobenzene을 투여해 간 손상의 model을 만든 다음 실험을 행하였을 때, diallyl disulfide를 전처치한 실험군이 대조군에 비하여 간손상의 정도가 경미하게 나타났다. 한편 diallyl disulfide의 간손상예방 효과 기전을 구명할 목적으로 bromobenzene의 활성화 및 해독 관련 효소들의 활성을 검토하였을때 활성화 효소인 aniline hydroxylase와 해독 효소의 일종인 epoxide hydrolase의 활성은 diallyl disulfide 전처치에 의해 변동이 없었으나, 나머지 해독 효소인... -

생쥐 간세포(肝細胞)의 미세구조(微細構造)에 미치는 메틸수은(水銀)의 독성적(毒性的) 영향(影響)과 이에 대한 홍삼(紅蔘) 추출물(抽出物)의 해독효과를 전자현미경적(電子顯微鏡的)으로 연구하였다. 대조군(對照群)의 간세포(肝細胞)에 비하여 메틸수은(水銀)만을 투여(投與)한 군(群)에서는 핵(核)의 일부가 붕괴(崩壞)되고, mitochondria의 팽대(膨大), cristae의 수축(收縮) 내지 손실(損失) 및 다수의 대형 강포(腔胞)의 출현(出現)이 일어나고 glycogen의 양(量)이 감소되었다. 메틸수은(水銀)과 홍삼(紅蔘) 추출물(抽出物)을... -

Secondary Fish-Odor Syndrome Can be Acquired by Nitric Oxide-mediated Impairment of Flavin-containing Monooxygenase in Hepatitis B Virus-Infected Patients

대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 2004, Vol.8 No.4 7 213-218 (6 pages)
Primary fish-odor syndrome (FOS) is a genetic disorder caused by defective flavin-containing monooxygenase 3 gene (FMO3) with deficient N-oxidation of trimethylamine (TMA), causing trimethylaminuria (TMAU). By contrast, secondary FOS can be acquired by decreased FMO activities in patients with chronic liver diseases, but the underlying mechanisms are unknown. In the present study, we examined plasma NOx concentrations and viral DNA contents as well as in vivo FMO activities and their... -

Our earlier studies found a significant correlation between the activities of ranitidine N-oxidation catalyzed by hepatic flavin-containing monooxygenase (FMO) and the presence of mutations in exon 4 (E158K) and exon 7 (E308G) of the FMO3 gene in Korean volunteers. However, caffeine N-1 demethylation (which is also partially catalyzed by FMO) was not significantly correlated with these FMO3 mutations. In this study, we examined another common mutation (V257M) in exon 6 of FMO3 gene. The V257M... -

on cyclosporine-induced kidney mitochondrial damage. Damaging effect of 50 μM cyclosporine plus 20 μM Fe2 on mitochondrial lipids and proteins of rat kidney and hyaluronic acid was greater than the summation of oxidizing action of each compound alone, except sulfhydryl oxidation. Cyclosporine and 100 μM ascorbate showed an enhanced damaging effect on lipids but not on proteins. The peroxidative action of cyclosporine on lipids was enhanced with increasing concentrations of Fe2.... -

대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 1997, Vol.1 No.5 15 591-595 (5 pages)
An ex vivo assay determining the flavin-containing monooxygenase (FMO) activity in perfused rat liver has been developed by assessing the rate of thiobenzamide S-oxide (TBSO) formation from the infused thiobenzamide (TB). The hepatotoxicity by TB or TBSO was not a critical factor for maintaining the FMO activity for up to 50 min. The FMO activity expressed in nmoles TBSO produced/g liver/min was the same for the recycling and non-recycling perfusion. This implies that reduction of the oxidized... -
