Synthesis rates of albumin and fibrinogen were determined in six patients with acute virus hepatitis and in nine control patients using the 14C carbonate method of McFarlane. Five patients were restudied several weeks after complete recovery. The following results were obtained. (1) The mean albumin and fibrinogen synthesis rates in the control group were 238.8 and 23.5 mg/kg/day, respectively. (2) In two patients with mild courses of hepatitis and in one patient studied during the early phase of a rapid and fatal course the albumin synthesis rate during the acute disease did not differ from controls whereas fibrinogen synthesis rate was slightly increased. (3) Three patients with severe hepatitis showed a definite decrease in albumin and fibrinogen synthesis rates, the lowest value being 76 mg/kg/day for albumin and 6.3 mg/kg/day for fibrinogen. (4) The decrease in plasma protein synthesis correlated neither with serum transaminase or bilirubin levels nor with plasma albumin or fibrinogen concentrations during the acute phase. (5) The two patients with the lowest albumin and fibrinogen synthesis rates also showed a definite decrease of the prothrombin index during the acute phase. Both patients presented very prolonged courses of the disease. (6) In all patients studied twice, plasma protein synthesis rates were normal after recovery.

Sera from patients with halothane hepatitis contain immunoglobulin G (IgG) antibodies to trifluoroacetylated liver microsomal proteins of 100, 76, 59, 57 and 54 kDa, which are produced as a consequence of metabolism of halothane to trifluoroacetyl halide by cytochrome(s) P450. In the present study, the membrane topographies of the various antigens in rat liver microsomal fractions were investigated. Liver microsomal fractions from rats treated with halothane in vivo, and rat liver microsomal fractions which had been incubated with halothane in vitro, were used as the source of trifluoroacetyl antigens. The antigens were detected by immunoblotting. Whereas the 100, 76, 59 and 57 kDa antigens were solubilized from the microsomal membrane by either 0.1 M sodium carbonate or 0.1% (w/v) sodium deoxycholate, the 54 kDa antigen was not solubilized by 0.1% (w/v) sodium deoxycholate. In intact microsomal fractions, the 100, 76, 59 and 57 kDa antigens were not degraded appreciably by trypsin unless detergent was added to permeabilize the microsomal membrane. These results indicate that the 54 kDa antigen is an integral membrane protein, whereas the 100, 76, 59 and 57 kDa antigens are peripheral membrane proteins situated within the lumen of microsomal vesicles, and hence presumably located within the lumen of the endoplasmic reticulum in vivo.

A decrease in sodium, potassium and anion (HCO3)-activated erythrocyte ATPases is noted in patients with acute viral hepatitides A and B, chronic persisting hepatitis, liver cirrhosis, chronic cholecystitis and in HBs-antigen carriers, the reduction of HCO8-ATPase being more noticeable. A degree of expression of the above changes depends on the severity of a pathological process in the liver. The most serious changes are noted in liver cirrhosis. In this disease calcium ATPase activity is also on a decrease. Erythrocyte ATPase activity is lowered in chronic cholecystitis to a lesser degree. In patients with chronic persisting hepatitis and liver cirrhosis erythrocyte ATPase activity slightly increases, however it remains significantly lowered as compared to the control level. The determination of erythrocyte ATPase activity can be used for assessment of the status of patients with acute and chronic liver diseases.

A 28-year-old man ingested methylene dianilene in potassium carbonate and gamma-butyrolactone. He developed toxic optic neuritis, with severe visual dysfunction (not previously reported in humans), prolonged toxic hepatitis, with disturbed liver-function tests 18 months after the incident, and other more transient effects. The course of his illness is described and the literature on methylene dianilene toxicity is reviewed.

A serum from a patient with HBV hepatitis was found to contain autoantibodies reacting with various mammalian cells. Immunofluorescence staining of cultured cells with the autoantibodies revealed that the antigen was localized at perinuclear regions, where the Golgi markers alpha-mannosidase II and beta-COP were colocalized. The autoantigen disappeared from the perinuclear regions upon incubation with the fungal metabolite brefeldin A, and the immunostainable structures were fragmented into vesicles by treatment with nocodazole. These results strongly indicate that the antigen is localized at the Golgi complex. Immunoblots of cell lysates showed that the autoantibodies recognized a single protein with a molecular mass of 230 kDa in a variety of cell lines, indicating that the 230-kDa antigen is a conserved protein among mammalian species. We designated this protein GCP230 (Golgi complex-associated protein with a molecular mass of 230 kDa). when a postnuclear fraction was prepared and centrifuged, GCP230 was recovered in both cytosol and membrane fractions. Peripheral interaction of GCP230 with membranes was confirmed by phase separation in Triton X-114 solution and by extraction with sodium carbonate. Taken together, these results indicate that GCP230 is a peripheral membrane protein of the Golgi derived from the cytosol, although its function is not known at present.

A course of silicic sapropel applications compared to calcareous sapropel induced a reversible fall of total lipid concentration in blood serum of intact rats. Sapropels of different kinds and of the same kind but obtained from different depths of the same deposit varied by their ability to correct hepatic function in rats with toxic hepatitis. The highest benefit was registered in application of carbonate sapropels taken from the depth of 1.5-2.5 m.

Ions hydrogene concentration in fluids and tissues is one of the strict regulated physiological organism variables. Most common man and animal diseases are accompanied with compensated acid-base balance shift development. But diagnosis of metabolic acidosis and alkalosis with blood indices (pH, pCO2, HCO3) doesn't reflect true tissue condition that is connected not only with respiratory and excretion system functioning but with hypercompensation of metabolic processes. Excess organic acid formation in case of metabolic alkalosis formation in tissues directed to support pH leads to acidification, what brings an essential mistake in pathogenesis understanding of such diseases as cardiomyopathy, ischemic cardiac disease, myocardial infarction, hepatitis, collagenosis, caries, peptic ulcer, macula dystrophy, atherosclerosis, virus diseases, radiation damages. Ignorance primary tissue damages doesn't allow to conduct necessary preventive measures and to cure disease. It is suggested to assess development of metabolic acidosis and alkalosis by compensated changes of regulation acid-base homeostasis system, which is the basis of all future damages and development of different diseases against this background.

A 29-year-old male patient with acute hepatitis B developed agranulocytosis about 2 months after the clinical onset of the hepatitis. Bone marrow examination showed hypercellularity and maturation arrest of myeloid leukogenesis at the stage of metamyelocyte. Anti-neutrophil antibody was negative. Since the patient did not show spontaneous recovery for 2 months, the patient received granulocyte-colony stimulating factor, but the therapy was a very short course because he had an elevation of temperature and nausea. Sixty-eight days after admission, he was started on lithium carbonate at a dose of 600 mg per day. About 3 weeks later, peripheral granulocyte counts had recovered to normal level.

Autoimmune liver diseases (AILDs) are a group of liver disorders composed of autoimmune hepatitis (AIH), primary biliary cholangitis (PBC), and primary sclerosing cholangitis (PSC) characterized by chronic hepatic and biliary inflammation. Although several genetic factors, such as HLA alleles, TNFA, and CTLA-4, have been reported in the pathogenesis of AILDs, many details remain unknown. In recent years, microRNAs (miRNAs) have emerged as crucial components in the diagnosis and therapeutic applications of various autoimmune diseases, including systemic lupus erythematosus (SLE), glomerulonephritis, and AILDs. MiRNAs comprise a class of small, noncoding molecules of 19--25 nucleotides that modulate multiple genes by suppressing or degrading target mRNAs. Altered miRNA profiles have been identified in serum, immune cells, and live tissues from AILD patients. Elevated serum miR-21 and miR-122 levels in AIH patients as well as decreased miR-200c levels in PSC patients indicate their diagnostic utility. Highly expressed miR-122 and miR-378f as well as downregulated miR-4311 and miR-4714-3p in serum samples from refractory PBC patients suggest their potential to evaluate treatment efficacy. Moreover, miRNAs have been reported to participate in AILD development. Increased miR-506 levels may impair bile secretion in PBC by inhibiting Cl-/HCO3-anion exchanger 2 (AE2) and type III inositol 1,4,5-trisphosphate receptor-3 (InsP3R3). Additionally, different miRNA mimics or antagonists, such as atagomiR-155 and miR-223 mimics, have been widely applied in experimental AILD murine models with great efficacy. Here, we provide an overview of miRNAs in AILDs, aiming to summarize their potential roles in diagnosis and therapeutic interventions, and we discuss the challenges and future applications of miRNAs in clinical practice.
