Liver and serum xanthine oxidase(XOD) activity were determined in rats treated with DL-ethionine. Concomitantly, the enzyme activity was compared with that of rats treated with CCl$_{4}$, actinomycin D and those fed a protein depleted diet. The activity of XOD in liver was inhibited by injection of ethionine to the rats. But, there were no differences in activity of serum XOD between control group and ethionine-treated rats. And the pattern of changes in enzyme activity of serum and liver in ethionine-treated rats, was similar with actinomycin D treated rats or those fed a protein depleted diet. On the other hand, the activity of XOD was rather elevated both in serum and liver by injection of CCl$_{4}$ to rats.

The effect of hepatic injury produced by CCL, was studied on rats receiving a low protein-high carbohydrate (7% casein), standard protein (20% casein) and a high protein diet (30% casein). The rats fed low protein diet are resistant to CCl$_4$ in its effects on the liver as judged by histology, serum enzymes(guanase, ALT) and the content of hepatic protein. On the other hand, the pretreatment of hydrocortisone before injection of CCl$_4$ to the rats fed a standard diet, slightly decreased both serum ALT and guanase activities. In the pretreatment of actinomycin D, the liver and serum guanase activities were significantly decreased. It indicates that the cause of increasing serum guanase is based on the alteration of membrane permeability and the result of accelerated enzyme synthesis in liver cells of CCl$_4$ intoxicated rats.

Background: Gastrointestinal tract cancers are among the most common cancers in Iran and comprise approximately 38% of all the reported cases of cancer. This study aimed to describe the epidemiology and to investigate spatial clustering of common cancers of the gastrointestinal tract across the counties of Iran using full Bayesian smoothing and Moran I Index statistics. Materials and Methods: The data of the national registry cancer were used in this study. Besides, indirect standardized rates were calculated for 371 counties of Iranand smoothed using Winbug 1.4 software with a full Bayesian method. Global Moran I and local Moran I were also used to investigate clustering. Results: According to the results, 75,644 new cases of cancer were nationally registered in Iran among which 18,019 cases (23.8%) were esophagus, gastric, colorectal, and liver cancers. The results of Global Moran's I test were 0.60 (P=0.001), 0.47 (P=0.001), 0.29 (P=0.001), and 0.40 (P=0.001) for esophagus, gastric, colorectal, and liver cancers, respectively. This shows clustering of the four studied cancers in Iran at the national level. Conclusions: High level clustering of the cases was seen in northern, northwestern, western, and northeastern areas for esophagus, gastric, and colorectal cancers. Considering liver cancer, high clustering was observed in some counties in central, northeastern, and southern areas.

The purpose of this study was to evaluate alcohol consumption and nutritional status in patients with alcoholic liver disease. The subjects were 80 patients with alcoholic liver cirrhosis and 12 patients with alcoholic fatty liver. Also 57 alcoholics without liver disease, 32 patients with viral liver cirrhosis and 194 normal men were included as control groups. Data on anthropometric index, socioeconomic status, alcohol consumption, dietary habits and dietary intakes were collected by individual interview. Alcoholic liver disease group had significantly lower triceps skinfold thickness and mid-uppr-arm circumferences than other groups. Socioeconomic status of alcholoci subjects was middle class or lower than that. The amount, duration and frequency of alcohol consumption were significantly higher and the quality of side dishes consumed with alcoholic beverage was significantly poorer in patients with alcoholic liver cirrhosis than others. Patients with alchololic liver disease ingested approximately 40% of daily caloric intake as alcohol and all alcoholic subjects had lower average intakes of protein, carbohydrates, fat, vitamins and minerals as compared with Korean adult average intakes. The results suggest that alcohol and poor dietary intake could cause malnutrition and might be two of the important risk factors to develop alcoholic liver disease in alcoholics. But other factors like genetic and immunological factors should be also considered in elucidating the causes of alcoholic liver disease. An extensive nutritional education should be emphasized for alcohol consuming population to prevent development of alcoholic liver disease.

Liver transplantation is widely accepted as an effective therapeutic modality for a variety of irreversible acute and chronic liver diseases for which no satisfactory therapy is available. Following the first unsuccessful efforts at human liver transplantation in 1963, development of the procedure evolved at first slowly and steadily for 20 years and then rapidly over the past two decades. The growth of liver transplantation was facilitated by the conclusion of the national institutes of health consensus development conference in 1983 that liver transplantation is not an experimental procedure but an effective therapy that deserves broader application. The number of liver transplantations increased 2.4-fold(from 1.713 to 4.058) from 1988 to 1996. but the number of patients on the UNOS(united network of organ sharing) liver list increased 12.1-fold(from 616 to 7,467); as would be expected, the number of deaths of listed patients increased 4.9-fold(from 195 to 954), The current supply of donor livers is insufficient to meet this need, and organ donation has been stagnant or increased by only a few percent in recent years. These facts underscore the importance of the appropriate selection of candidates for liver transplantation and the development of operative procedures, such as living donor liver transplant, split liver transplant and auxiliary partial liver transplant.

Chronic liver diseases, including cancer, are characterized by inflammation and elevated serum ferritin (SF). However, the causal-relationship remains unclear. This study used primary rat hepatic stellate cells (HSC) as a model to investigate effects of physiological SF concentrations (10, 100 and 1000 pM) because HSCs play a central role in the development and progression of liver fibrosis. Physiological concentrations of SF, either horse SF or human serum, induced pro-inflammatory cytokine $IL1{\beta}$, IL6 and $TNF{\alpha}$ secretion in rat activated HSCs (all p<0.05). By contrast, treatment did not alter activation marker ${\alpha}SMA$ expression. The presence of SF markedly enhanced expression of Grp78 mRNA (p<0.01). Furthermore, transient knock down of Grp78 by endotoxin EGF-SubA abolished SF-induced $IL1{\beta}$ and $TNF{\alpha}$ secretion in activated HSCs (all p<0.05). In conclusion, our results showed that at physiological concentrations SF functions as a pro-inflammatory mediator in primary rat HSCs. We also provide a molecular basis for the action of SF and identified Grp78-associated ER stress pathways as a novel potential therapeutic target for resolution of fibrosis and possible prevention of liver cancer.

GATA-binding protein-3 (GATA-3) and T-box expressed in T-cells (T-bet) are now considered as master transcription factors involving Th cell differentiation, but the roles of these factors are still uncertain in vivo. This study was conducted to investigate the expression of these transcription factors in the liver damage induced by carbon tetrachloride ($CCl_4$) in rats. In this study, liver damage were induced with Scutellaria baicalensis Georgi water extracts (SBW) and followed for 4 weeks. The expression of GATA-3 and T-bet protein in liver damage induced by $CCl_4$ and the serum levels of immunoglobulin A (IgA), IgE were studied after 4 weeks of treatment. We found that effect of SBW on IFN-$\gamma$, STAT1, pSTAT1 and T-bet was decreased in vivo. Several genes were demonstrated to be IL-4 inducible prior to the discovery of STAT6. $CCl_4$+SBW group was significantly lower than $CCl_4$ group in IL-4, STAT6, pSTAT6 and GATA-3. Our data indicate that cytokine protein production were increased in $CCl_4$ group and $CCl_4$+SBW group. From these results, water extracts obtained from Scutellaria baicalensis Georgi may have an immunoregulatory effect in the liver induced by $CCl_4$ of rats.
