Summary The purpose of this study was to investigate the galactose single point (GSP) method, a residual liver function test recently recommended by the US Food and Drug Administration, which can be a useful tool for rat liver function measurement. Rats were treated either with carbon tetrachloride (CCl4) alone (1 mL/kg, intraperitoneally [i.p.]) for one day or with isoniazid (INH) alone (150 mg/kg, i.p.) or (in order to ameliorate the effects of INH) with a combination of INH and bis- p-nitrophenyl phosphate (BNPP) (25 mg/kg, i.p.) for 21 days. Hepatotoxicity was assayed by plasma aspartate aminotransferase (AST) and alanine aminotransferase (ALT) activities and scores of histological activity index-necroinflammation (HAI-NI) of the respective liver specimens. The GSP method in rats was defined by the galactose blood level after 60 min. Significant differences in GSP values were observed between controls and the CCl4-treated rats. After 21 days of treatment, no significant changes in AST and ALT values were observed among the control, INH and INH-BNPP groups. There were significant differences in average GSP values for controls ( P < 0.001) and INH-BNPP ( P < 0.001) compared with INH alone. Highly significant correlations ( P < 0.001) were obtained between GSP and scores of HAI-NI for all the groups. GSP was concluded to be a more sensitive biomarker of INH-induced hepatotoxicity than AST or ALT in the rats. The GSP method has been proved to be a simple and useful tool for the quantitative determination of liver function in rats, which can possibly be extended to other animals.

SummaryPlasma urokinase antigen levels were studied in 78 patients suffering from liver diseases. Blood was drawn before any specific medication was initiated. Impairment of liver function was comparable in all patients. In both groups of cirrhotic liver disease (alcoholic and non-alcoholic), normal levels of plasma urokinase antigen were found as compared to age-matched control groups. In both groups of patients with hepatomas (with or without a history of liver cirrhosis), however, significantly increased plasma urokinase antigen levels could be determined. These data indicate that an increase in plasma urokinase antigen might rather relate to malignant growth in liver disease than to impaired liver function.

Purpose: Liver failure is a major cause of early mortality followinghepatectomy. The future-remnant liver function is an important factor whenassessing the risk for postoperative liver impairment. Several techniques havebeen established for this evaluation, including the ICG test. Aim of the study isto evaluate the ICG clearance in patients scheduled for liver resectionregarding perioperative and postoperative risk factors.Methods: Thirty-one patients, scheduled for liver resection, underwent theICG test. Peri-operative and postoperative variables were recorded andanalyzed using non-parametric tests.Results: Procedures extended from wedge excisions to extendedhepatectomies. Major complications included 1 case of a non-ST elevationmyocardial infarct, 1 case of inferior vena cava thrombosis, 2 cases of liverinsufficiency and 1 case of renal failure. Two patients died due to myocardialinfarction and postoperative liver failure respectively. PDR was foundpositively correlated with total blood loss, transfusion and operation duration.Conclusions: The role of residual liver function and particularly the hepaticreserve assessment on liver surgery may be of most benefit in the routinestratification of risk, enabling surgical procedures to be performed with safety.In this study, the ICG clearance markers were found significantly correlated with perioperative risk factors in histologically „normal‟ liver parenchyma.Interpretation of ICG clearance results may appraise in these patients aninadequate hepatic reserve in the remaining parenchyma postoperatively.Thus, in addition to CT volumetry, functional assessment of the hepaticreserve with ICG may persuade the preoperative planning and preventpostoperative liver failure.

Background. Although liver retraction using n-butyl-2-cyanoacrylate (NBCA) glue has been applied to laparoscopic upper abdominal surgery in noncirrhotic patients, there is still no consensus on its safety and feasibility for cirrhotic patients. In this study, we aimed to investigate the safety and effectiveness of liver retraction using NBCA glue during laparoscopic splenectomy and azygoportal disconnection (LSD) for gastroesophageal varices and hypersplenism secondary to liver cirrhosis and portal hypertension. Methods. Thirty-nine gastroesophageal varices and hypersplenism secondary to liver cirrhosis and portal hypertension patients were included in our study. We performed LSD in the presence of NBCA glue (n = 22, NBCA group) and absence of NBCA glue (n = 17, n-NBCA group), respectively. The operation time, blood loss, postoperative hospitalization, and liver function were compared between the two groups. Results. There was no mortality during the operation. One patient in non-NBCA group received open surgery due to parenchyma hemorrhage. Postoperative pleural effusion occurred in 2 cases of the NBCA group and 1 of the non-NBCA group. One showed left subphrenic abscess in the non-NBCA group. No postoperative bleeding occurred after 9-30 months of follow-up. The time of operation in NBCA group was significantly shorter than those in n-NBCA group (198.86±17.86 versus 217.81±20.25min, P<0.01). Blood loss in NBCA group was significantly lower than non-NBCA group (159.09±56.98 versus 212.50±88.51 ml, P<0.05). The levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were increased on day 1 after LSD and decreased to normal level on day 7 after LSD in both groups. There was no significant difference in postoperative hospitalization and liver function between the two groups. Conclusion. Liver retraction using NBCA glue during LSD for gastroesophageal varices and hypersplenism secondary to liver cirrhosis and portal hypertension is safe, effective, and feasible.

AbstractLiver function is a most important prognostic factor in patients with liver cirrhosis. Also, portal hypertension is a fatal complication of liver cirrhosis and variceal treatment is indispensable. However, changes of liver functions after endoscopic variceal treatments are unknown. The aim of this study was to evaluate prognosis and liver functions after endoscopic injection sclerotherapy (EIS) and endoscopic variceal ligation (EVL). A total of liver cirrhotic 103 patients who underwent prophylactic EIS and EVL were enrolled. Overall survival rate was higher in EIS group than EVL group (p = 0.03). Multivariate analysis showed that EIS was a negative factor for death (HR: 0.46, 95% confidence interval: 0.24–0.88, p = 0.02). Liver functions were assessed by blood test taken at before and 3 months after treatment. In EIS group, albumin and prothrombin time improved (p < 0.01), leading to improvement of Child–Pugh score, ALBI score and MELD score (p < 0.05). However, these did not improve in EVL group. EIS was a significant factor related to the elevated value of albumin after treatment in linear regression analysis (estimated regression coefficient: 0.17, 95% confidence interval: 0.05–0.29, p = 0.005). These results revealed that EIS could improve liver functions and prognosis.

Height Distribution

We study the limiting distribution of the height in a generalized trie in which external nodes are capable to store up to $b$ items (the so called $b$-tries). We assume that such a tree is built from $n$ random strings (items) generated by an unbiased memoryless source. In this paper, we discuss the case when $b$ and $n$ are both large. We shall identify five regions of the height distribution that should be compared to three regions obtained for fixed $b$. We prove that for most $n$, the limiting distribution is concentrated at the single point $k_1=\lfloor \log_2 (n/b)\rfloor +1$ as $n,b\to \infty$. We observe that this is quite different than the height distribution for fixed $b$, in which case the limiting distribution is of an extreme value type concentrated around $(1+1/b)\log_2 n$. We derive our results by analytic methods, namely generating functions and the saddle point method. We also present some numerical verification of our results.
