The diagnosis of dilated cardiomyopathy associated with pheochromocytoma was made in a 24 year old male on the basis of symptoms and signs, measurements of metabolites of catecholamine,echocardiography and radionuclide ventriculography were preformed and demonstrated. The presence of a tumor on both adrenal glands without definite distant metastasis was demonstrated by abdominal ultrasonography, CT scanning and 131I-MIBC scintigraphy. Surgical removal was performed after proper preoperative preparation with a-adrenergic blocker. During the surgery, neither significant arrhythmia nor severe change of blood pressure was observed. After surgery, cardiac function of the patient improved slowly and progressively.

PURPOSE: To determine the hepatic and vascular enhancement profiles with nonionic dimeric, iodixanol, contrast agent in the rabbit and to compare them with nonionic monomeric, ioversol, contrast agent. MATERIALS AND METHODS: Seven rabbits initially underwent hepatic dynamic CT scan with either iodixanol or ioversol, followed by repeated CT scan with other unused contrast agent with one week interval between scans. Pre and post contrast attenuation values of hepatic parenchyma, aorta and portal vein were measured sequentially. The mean enhancement of the hepatic parenchyma, aorta and portal vein were compared between two agents. The mean peak enhancement and peak enhancement time of the liver, aorta, and portal vein were also compared. RESULTS: The attenuation values of ioversol showed a greater mean hepatic enhancement than iodixanol from 18 seconds to 39 seconds after injection (from late arterial phase to early portal venous phase) with a statistical significance (p<0.05). The mean peak enhancement of hepatic parenchyma, aorta and portal vein was also greater using ioversol than iodixanol, but the mean peak enhancement times of ioversol and iodixanol were nearly identical. CONCLUSION: Ioversol may have the greater effects than iodixanol on hepatic tumor conspicuity, especially from late arterial phase to early portal veneous phase.

Alcohol abuse and its medical and social consequences are a major health problem in many areas of the world. Korean red ginseng (KRG) has been traditionally used for the treatment of liver disease. This study was conducted to evaluate the hepatoprotective effects of KRG against hepatotoxicity in Sprague-Dawley rats treated with ethanol (EtOH). Administration of EtOH for 20 days induced significant changes in serum biochemical parameters (aspartate aminotransferase, alanine transaminase, and glucose) accompanied by histological changes in the liver tissue. Treatment with KRG prior to administration of EtOH inhibited the EtOH-induced biochemical and histological changes of the liver. In perfused rat livers, administration of EtOH caused an increase in lactate dehydrogenase (LDH) release into the perfusate and activated the pro-apoptotic Bax protein but inhibited the anti-apoptotic Bcl-2 protein. Pretreatment with KRG prior to administration of EtOH decreased the EtOH-induced LDH release and inhibition of Bcl-2 protein. These results suggest that KRG exerts anti-apoptotic effects and alleviated EtOH-induced liver injury in rats.

Objective: To investigate the protective effects of Nigella sativa seed extract (NSSE) against acetaminophen (APAP)-induced hepatotoxicity in TIB-73 cells and rats. Methods: Toxicity in TIB-73 cells was induced with 10 μmol/L APAP and the protective effects of NSSE were evaluated at 25, 50, 75, 100 μg/mL. For in vivo examination, a total of 30 rats were equally divided into five experimental groups; normal control (vehicle), APAP (800 mg/kg body weight single IP injection) as a hepatotoxic control, and three APAP and NS pretreated (2 weeks) groups (APAP + NSSE 100 mg; APAP + NSSE 300 mg and APAP + NSSE 900 mg/kg). Results: TIB-73 cell viability was drastically decreased by (49.0 ± 1.9)% after the 10 μmol/LAPAP treatment, which also increased reactive oxygen species production. Co-treatment with NSSE at 25, 50, 75, and 100 μg/mL significantly improved cell viability and suppressed reactive oxygen species generation. In vivo, the APAP induced alterations in blood lactate levels, pH, anionic gap, and ion levels (HCO
