BACKGROUND: The purpose of this study was to investigate whether the hepatic dysfunction associated with obstructive jaundice can be measured from changes in expiratory 13CO2 levels after intravenous administration of l-[1-(13)C]phenylalanine, using a rat model of obstructive jaundice. MATERIALS AND METHODS: Under pentobarbital anesthesia, bile duct ligation (BDL) was performed (n=12). In the control group, simple laparotomy was performed (n=12). On postoperative day 7, 20 mg/kg l-[1-(13)C]phenylalanine was administered via the femoral vein. Phenylalanine breath test (PBT) was performed for 30 min. We compared single point of 13CO2 level (SPT: T: min) and sum of 13CO2 output (ST) values between BDL and control rats. We examined the correlation of SPT or ST with phenylalanine hydroxylase activity (PHA) and blood chemical parameters. RESULTS: Both SPT and ST values decreased in BDL compared to control 3 min after the start of PBT (SP10; 103+/-12 (per thousand) versus 84+/-16 (per thousand) P=0.025). PHA/g liver in BDL was significantly decreased compared to control (40.81+/-4.80 (U) versus 28.93+/-9.60 (U) P=0.008). PHA/g liver was correlated with SPT with correlation coefficient of more than 0.715, 10 min after the start of PBT, and the maximum correlation was at SP20 (r=0.801). Blood chemical parameters were correlated with S15 (total bilirubin, r=-0.717; alkaline phosphatase, r=-0.841; gamma-glutamyl transpeptidase, r=-0.759; alanine aminotransferase, r=-0.776; albumin, r=0.819). CONCLUSIONS: In the breath test with intravenously l-[1-(13)C]phenylalanine, hepatic dysfunction associated with obstructive jaundice could be measured in a short period.  相似文献

The effects of OKY-046, a thromboxane A2 synthetase inhibitor, on hepatic dysfunction produced by liver cell ischemia were studied in an experimental model of rats with obstructive jaundice. The experiments were performed 7 days after the rats underwent bile duct ligation. Warm total ischemia of the liver was induced by Pringle's method over a 20-min period and the animals were divided into two groups according to whether or not OKY-046 was administered. The reperfusion time was 30 min in each group. OKY-046 was administered via the femoral vein at a rate of 100 g/kg per min from 15 min before the blockade to the end of the experiment. The level of ATP in the liver tissue of the OKY-046 group was elevated slightly, but not significantly, compared to that of the control group. The ratio TXB2/6-keto PGF1 in the liver tissue was lower in the OKY-046 group than in the control group, and significant differences were found between the two groups in the water content of the liver and the mitochondrial score as examined by transmission electron microscopy. Thus, it was observed that an improvement in the balance of TXA2 and PGI2 associated with OKY-046 administration protected the cellular structure of the mitochondria in the rat liver.  相似文献

Factors related to the prognosis of patients with hyperbilirubinemia were investigated in 16 highly jaundiced patients. Patients who died within 3 weeks showed a deterioration of the hepatic energy status, measured by the arterial ketone body ratio, but patients who did not die within 3 weeks after the measurement of the ketone body ratio had a ratio within the normal range, despite high total bilirubin levels (18 mg/0.1 L). C3, C4 and CH50 in the former were also significantly lower than those in the latter. However, endotoxin and high fever occurred to the same extent, in the both groups. Thus, hepatic energy balance is the most pertinent factor related to prognosis, and is concerned with both the hepatocyte and reticuloendothelial systems. On the other hand, infection or endotoxin, when the energy balance is disturbed, becomes an aggravating but not a fundamental factor.  相似文献

Intrabiliary rupture is the most frequently seen complication of the hepatic hydatid cysts. Obstructive jaundice can be seen as a complication of the intrabiliary ruptured hepatic hydatid cysts due to the migrated cystic content into bile ducts. In this study, we present two rare complications seen in a patient who has intrabiliary ruptured hepatic hydatid cyst. Obstructive jaundice and secondary gallbladder hydatidosis depending on to the intrabiliary ruptured hepatic hydatid cyst in a 58-year-old man patient were diagnosed and treated. A large choledochal nonfragmanted germinative membran was found in the choledochus as the reason of biliary obstruction. Hepatic hydatid cyst is a world-wide disease. Intrabiliary rupture must be kept in mind in the patients who has hepatic hydatid cyst and biliary tract problems.  相似文献

We studied whether the maximal excretion rate of indocyanine green (ICG Bmax) and the 2-h ICG excretion rate in the bile could be used to estimate the separate functions of the left and right liver in 20 patients with biliary obstruction at the hepatic hilus. ICG Bmax was measured after biliary decompression. An operative procedure that preserved the side of the liver with a positive ICG Bmax value was selected. Eighteen patients tolerated extensive hepatic resection, such as right trisegmentectomy, extended right lobectomy, extended left lobectomy, or left lobectomy. However, prolonged jaundice was observed postoperatively in five of the six patients with 2-h excretion rates of less than 25% and who had undergone extended right lobectomy. One patient on whom extended right lobectomy had been performed died because of postoperative hepatic failure. His ICG Bmax value was +0.6 and his 2-h excretion rate was very low (3%). ICG Bmax and the 2-h excretion rate in the bile reflected well the degree of separate hepatic dysfunction in patients with biliary obstruction at the hepatic confluence. If ICG Bmax value is more than +1.0, resection of more than two segments, such as trisegmentectomy or extended hepatic lobectomy, may be tolerated, and if the ICG Bmax value is positive, hepatic lobectomy may be tolerated. ICG Bmax and 2-h excretion rate in bile are useful indicators of hepatic functional reserve of the separate lobes of the liver in patients with biliary obstruction at the hepatic hilus.  相似文献

BACKGROUND: Hyperbilirubinemia occurs as a sign of hepatic failure after hepatectomy. The pathogenesis of this event has not been elucidated. In cases complicated with postoperative infection, hyperbilirubinemia is prolonged and the composition of bilirubin subfractions in bile changes markedly. A reduction in the proportion of bilirubin diglucuronide (BDG) is especially notable. This study was aimed at clarifying the relationship between infection and biliary bilirubin subfractions, with a view to shedding light on the mechanisms of change. MATERIALS AND METHODS: Rats underwent either laparotomy or partial hepatectomy (Hx). Daily intraperitoneal injections of lipopolysaccharide (LPS) or natural saline were administered for 3 days following surgery. Total serum bilirubin levels and proportions of BDG and bilirubin in bile were measured until Day 5 after the operation. Hepatic levels of UDP-glucuronic acid (UDP-GA), UDP-glucose, NAD(+), and total adenine nucleotides (TAN) and activities of UDP-glucuronyltransferase (UDP-GT) and UDP-glucose dehydrogenase were measured on Day 4. RESULTS: In hepatectomized rats treated with LPS (Hx-LPS), total serum bilirubin levels were elevated, biliary bilirubin levels were decreased, and the proportion of biliary BDG was decreased on Day 4. Hepatic levels of UDP-GA, NAD(+), and TAN and activities of UDP-GT in Hx-LPS were reduced. In all groups tested, a significant linear correlation between BDG and UDP-GA and between UDP-GA and NAD(+) was found. CONCLUSIONS: The reduction of UDP-GA might be effected by reduced hepatic levels of NAD(+) in endotoxemia following hepatectomy. It is therefore suggested that alterations in biliary bilirubin subfractions might accurately reflect the energy state of the remnant liver following hepatectomy.  相似文献

Seven spontaneously hypertensive rats (SHRs) and eight Wistar-St rats were used to assess the influence of hemorrhage on myocardial and hepatic energy metabolism. They received 2% halothane and pancuronium, 0.3mg·kg–1, during preparation. After discontinuation of halothane, blood (2ml·100g body weight–1) was gradually withdrawn over a 5min period from a femoral artery. Thirty min after induction of hemorrhage, the heart and liver were removed and myocardial and hepatic metabolites (ATP, lactate, pyruvate and glycogen) were measured by the enzymatic methods. Acidosis and decreased hematocrit were noted in the both groups after hemorrhage. Mean arterial pressure (MAP) in SHR was significantly higher than that in Wistar rat before hemorrhage. However, there were no significant differences in MAP and heart rate between the two groups after hemorrhage. Although there were no significant differences in cardiac metabolites, a significant decrease of hepatic ATP and an increase of hepatic lactate/pyruvate ratio were found in SHR when compared with Wistar rat. These results suggest that human hypertensive disease may run a high risk in connection with acute hemorrhage.(Kashimoto S, Nonaka A, Nakamura T, et al: Cardiac and hepatic metabolism in spontaneously hypertensive rats following acute blood loss.

Cyclosporine (CyA) is eliminated from the body via biliary excretion at a rate directly proportional to bile production and the functional status of the liver. Previous reports demonstrated that disturbances in the hepatic excretory function with a rise in the plasma bilirubin level are positively correlated with high blood concentrations of CyA and CyA plus metabolites (CyA + M). Less information is available about the blood concentrations of the CyA parental substance or CyA metabolites in the case of liver dysfunction when there was no elevation of serum bilirubin content. To answer this question, we compared the pharmacokinetic profile of CyA in a cholestatic and in a ischemic model in pigs. Our results show that in pigs receiving a single dose of CyA after liver ischemia, the blood concentrations of CyA and CyA + M are significantly increased independently of the serum bilirubin concentration, probably through a slow down of CyA metabolism by impairment of cytochrome P450 III A.  相似文献

BACKGROUNDGiant simple hepatic cysts causing intrahepatic duct dilatation and obstructive jaundice are uncommon. A variety of measures with different clinical efficacies and invasiveness have been developed. Nonsurgical management, such as percutaneous aspiration and sclerotherapy, is often applied. CASE SUMMARYThe case is a 39-year-old female with a 5-mo history of cutaneous and scleral icterus, loss of appetite, and dark urine. Lab tests showed jaundice and liver function abnormalities. Imaging revealed a giant simple hepatic cyst obstructing the intrahepatic bile ducts. A combination of percutaneous catheter aspiration and lauromacrogol sclerotherapy was successfully performed and the effects were satisfactory with the size of cyst decreasing from 13.7 cm × 13.1 cm to 3.0 cm × 3.0 cm. Further literature review presented the challenges of managing giant simple hepatic cysts that cause obstructive jaundice and compared the safety and efficacy of a combination of percutaneous aspiration and lauromacrogol sclerotherapy with other management strategies.CONCLUSIONGiant simple hepatic cysts can cause obstructive jaundice, and a combination of percutaneous catheter aspiration and sclerotherapy with lauromacrogol are suggested to treat such cases.  相似文献

To clarify the mechanism of metabolic derangement by massive blood transfusion to the damaged liver, the changes in the hepatic mitochondrial redox state, as reflected in arterial ketone body ratio (acetoacetate/3-hydroxybutyrate), were studied in jaundiced rabbits by infusion of massive citrate-phosphate-dextrose (CPD) solution. The jaundiced rabbits received common bile duct ligation (BDL group), and the sham group had a simple exploration of the bile duct. CPD solution was infused for 3 h at a rate of 9 ml/kg/h in each group. As metabolic parameters, blood gas, pyruvate, lactate, citrate and ketone body ratio were analyzed in the arterial blood. During the course, arterial ketone body ratio decreased significantly (p less than 0.01) in the BDL group with severe metabolic acidosis, while it was maintained at high value in the sham group with metabolic alkalosis. Organic acids were more highly accumulated in the BDL group than in the sham group. These results suggested a hepatodepressant effect of massive blood transfusion, especially in the damaged liver.  相似文献

Prognosis of the posttraumatic vegetative state   总被引:8,自引:0,他引:8  
Summary Of 1373 patients who, following severe brain injury had been comatose for over 6 hours, 140 (10%) were in a vegetative state one month later. Fifty-nine regained consciousness but none of those aged over 40 became independent during the first year. Of those still in a vegetative state after 3 months, none became independent irrespective of age. Of all patients comatose for over 6 hours after severe brain injury, only 1% was in a vegetative state after one year.Certain scores for features such as age, pupillary reactions, eyeopening and eye movements indicate either a favourable prognosis, a fatal outcome or irreversible coma. It is only in some 10% of all patients in coma or in a vegetative state during the first two weeks after the accident that it is possible to predict with a high degree of probability (p > 0.95), an unfavourable outcome (death or irreversible coma) within one year. At no time after the onset of coma is it possible to predict or distinguish, with a fair degree of probability (e.g. p > 0.80), those patients who will remain in a vegetative state from those who will die.  相似文献
