  • This study was investigated the effects of exercise and supplementation of L-carnitine and antioxidants on hepatic mitochondrial function, especially oxidative phosphorylation (OXPHOS). Isolated hepatic mitochondria from 4 rat groups were functionally tested by an analysis of respiration and the coupling of this process to ATP synthesis in the presence of ADP. Four groups were non-trained, non-supplemented group (NTNS), non-trained, supplemented group (NTS), long term-trained, non-supplemented group (LTNS) , and long term-trained, supplemented group (LTS). The trained rats run on a treadmill (grade 10°,20 m/min) for 60min/day for 8 weeks. The supplemented rats were treated with L-carnitine (0.5% diet), vitamin E(0.5mg/g BW), vitamin C (0.5mg/g BW) and melatonin (1 $\mu$ g/g BW) for 8 weeks. There were exercise effects on improving mitochondrial OXPHOS. Within non-supplemented groups, exercised rats resulted in a significant decrease in state 4 oxygen consumption, which increased the respiratory control (RC) ratio and ADP : O (P/O) ratio. There were supplementation effects on improving mitochondrial OXPHOS, too. Within non-exercised rats, supplemented rats resulted in a significant decrease in state 4 oxygon consumption. which increased the RC ratio and P/O ratio. There were additive effects of exercise and supplementation on OXPHOS. Within supplemented rats, exercise resulted in an increase in RC ratio. Significant effects of exercise-supplement interaction on improving OXPHOS were identified. It suggests that exercise and supplementation of L-carnitine and antioxidants might improve more efficiently the impaired OXPHOS efficiency in mitochondrial dysfunction that recognized as is an important cause of degenerative diseases.

  • A 10 months old, male Poongsan dog was referred with a history of right forelimb lameness due to hit by a car a few hours before presentation. On the physical examination, the dog showed pale mucous membrane, respiration distress, and skin abrasions. The main laboratory finding was leukocytosis, while hematocrit was normal. Abdominal radiography revealed the loss of abdominal serosal detail, which was diagnosed as peritoneal hemorrhage on ultrasonography (US) and aspiration. On computed tomography (CT), hepatic and splenic injuries were seen characterized by the discontinuity of the capsule with irregular margin and lower density lesions than parenchyma. No contrast enhancing area were shown in the laceration lesion. The accessory spleen was incidentally found by US and CT. In this case, acute intra-abdominal hemorrhage from splenic and hepatic laceration was diagnosed using CT.

  • Diagostic imaging can help in management of toxicologic emergencies. We report a patient who presented to the emergency department with coma and suppressed respiration after ingestion of unknown substance. We documented chloroform with radiopaque material in bowel on abdominal radiograph. We used activated charcoal and laxative to decontaminate bowel. Hepatotoxicity occurred on 3rd admission day and elevation of liver enzyme reached peak level on 5th admission day. The patient received hemoperfusion, N-acetylsystein and supportive cares. The patient was improved from hepatic dysfunction and discharged without complication on 11th admission day. Radiograph in toxicology may confirm a diagnosis and assist in therapeutic intervention.

  • To investigate effects of ethanol and dietary fat on growth and bichemical indices of liver tissue and blood in rats 40 male rats of Sprague-Dawley wtrain weighing about 160g were divided into 5 groups (low-fat diet group ethanol-administered low-fat diet group high-fat diet group ethanol-administered high-fat diet group and commercial diet group) and fed expe-rimental diets for 8 weeks. Ethanol-administered groups consumed ethanol corresponding to 22 cal% which was considered as moderate drinking. Neither the ethanol intake nor the dietary fat level affected calorie intake. Nonetheless the low-fat diet group with ethanol had the lowest growth rate and 2-fold increase in the concentration of plasma triglyceride. There was no effect of ethanol and dietary fat level on contents of protein lipid and lipid composition of liver tissue. The level of lipid peroxide of liver tissue tended to be increased by ethanol intake but the increase was statistically insignificatnt. The low-fat ethanol group had lowered hepatic mitochondrial respiration rate and deformed structure of mitochondria of hepatocytes.

  • Copper sulfate is a copper compound used widely in the chemical and agriculture industries. Most intoxication occurs in developing countries of Southeast Asia particularly India, but rarely occurs in Western countries. The early symptoms of intoxication are nausea, vomiting, diarrhea, and abdominal cramps, and the most distinguishable clue is bluish vomiting. The clinical signs of copper sulfate intoxication can vary according to the amount ingested. A 75-year old man came to our emergency room because he had taken approximately 250 ml copper sulfate per oral. His Glasgow Coma Scale (GCS) score was 14 and vital signs were blood pressure 173/111 mmHg, pulse rate 24 bpm, respiration rate 24 bpm, and body temperature $36.1^{\circ}$ .... Arterial blood gas analysis (ABGa) showed mild hypoxemia and just improved after 2 L/min oxygen supply via nasal cannula. Other laboratory tests and chest CT scan showed no clinical significance. Three hours later, the patient's mental status showed sudden deterioration (GCS 11), and ABGa showed hypercarbia. He was arrested and his spontaneous circulation returned after 8 minutes CPR. However, 22 minutes later, he was arrested again and returned after 3 minutes CPR. The family did not want additional resuscitation, so that he died 5 hours after ED visit. In my knowledge, early deaths are the consequence of shock, while late mortality is related to renal and hepatic failure. However, as this case shows, consideration of early definite airway preservation is reasonable in a case of supposed copper sulfate intoxication, because the patients can show rapid deterioration even when serious clinical manifestation are not presented initially.

  • [here are so many reports that pulsatile blood flow provides physiologic organ perfusions during cardiopulmonary bypass. So, we compared the recent 30 cases undergoing cardiac surgery by Cobe-Stckert pulsatile roller pump with another 30 cases by Polystan nonpulsatile roller pump. Pulsatile flow was applied during aortic-cross clamping period when synchronized to internal EKG simulator, and perfusion mode was changed to continuous nonpulsatile flow after declamping of aorta. Age, sex, weight, and disease entities were comparable and operative techniques were similar between two groups. 1. There were no differences in average ACC time, ECC time, and Operation time. 2. Postoperative artificial respiration time was 6hrs 30mins in nonpulsatile group and 4hrs 48mins in pulsatile group, and detubation time after ventilator weaning was 2hrs 44mins in nonpulsatile group and 1hrs 43mins in pulsatile group. 3. Average pulse pressure was 8mmHg in nonpulsatile group and 55mmHg in pulsatile group, and a mean arterial pressure was 66.0mmHg in nonpulsatile group and 60.7mmHg in pulsatile group. 4. Mean urine-output during ACC;ECC period was 9.717.3;9.913.2ml/kg/hr in nonpulsatile group and 14.215.0;15.817.5 in pulsatile group [p<0, 05], and thereafter progressive decrease of differences in urine output between two groups until POD 2, and lesser amounts of diuretics was needed in pulsatile group during same postoperative period. Serum BUN/Cr level showed no specific difference and urine concentration power was well preserved in both groups. 5. Plasma proteins and other Enzymes showed no differences between two groups, but serum GOT/GPT level was higher in nonpulsatile group till POD 2. 6. Serum Electrolytes showed no differences between two groups. 7. WBC, RBC, Platelet counts, Hgb and Hct were not different and Coagulogram was well preserved in both groups. 8. Plasma free Hgb level was 7.09mg% in pulsatile group compared with 3.48mg% in pulsatile group on POD 1 but was normalized on POD 2. Gross hemoglobinuria after ECC was noted in 6 cases [20%] of pulsatile group and 4 cases [13%] of nonpulsatile group. 9. In both groups, most patients were included in NYHA class III to IV [28 cases;93% in nonpulsatile group, 22 cases;73% in pulsatile group] preoperatively, and well improved to class I to 11[22 cases; 73% in nonpulsatile group, 30 cases; 100% in pulsatile group] postoperatively. There were 7 operative mortalities in nonpulsatile group only, which were 5 cases of TOF with hepatic failure, 1 case of multiple VSDs with low out-put syndrome, and 1 case of mitral valvular heart disease with cardiomyopathy. We concluded that the new, commercially available Cobe-Stckert pulsatile roller pump device was safe, simple, and reliable.
