In the dephosphorylation of ATP’ by adult rat liver homogenates, a major role is played by a magnesium-stimulated ATPase localized in the isolated mitochondrial fraction (1). However, in liver tumors, as in other tumors tested, ATP dephosphorylation is catalyzed mostly by an apyrase, stimulated equally by calcium and magnesium ions and localized in the isolated microsome fraction (2, 3). It see...

Objectives: The natural origin of medicinal plants does not guaranteed their safety, as there are no sufficient studies on the safety, efficacy and toxicity to support their beneficial claims. Hence, this study aimed at investigating the oral acute toxicity of Adansonia digitata L. fruit shell extract on mice. Methods: Maceration method was employed for the extraction of Adansonia digitata fru...

BACKGROUND Liver/kidney microsomal antibody type 1 (LKM1) and liver cytosol antibody type 1 (LC1) are the serological markers of type 2 autoimmune hepatitis (AIH). AIMS Since LKM1 and LC1 react against two distinct liver specific autoantigens (cytochrome P450IID6 (CYP2D6) and a 58 kDa cytosolic polypeptide respectively), the aim was to see whether LKM1 and LC1 concentrations correlate with li...

The site of biosynthesis and intracellular deposition of dolichol in rat liver has been studied in vitro and in vivo. In vitro experiments using labeled isopentenylpyrophosphate indicated that dolichol was synthesized in the microsome fraction, and that this process required supplementation with the cytosol fraction, When labeled farnesylpyrophosphate and unlabeled isopentenylpyrophosphate were...

Claudin-4 (CLDN-4), a tight-junction protein, is overexpressed in various malignant tumors, including gastric, colorectal, pancreatic, and breast cancers. However, CLDN-4 is also expressed in normal tissues, including the liver, pancreas, kidney, and small intestine. Whether CLDN-4 is an effective and safe target for cancer therapy has been unclear owing to the lack of a binder with both CLDN-4...

1. Homologous vaccine was injected into abdominal organs of rabbits after different intervals following sensitization by a single or by repeated intracutaneous injections of heat-killed pneumococci Type I or of formalin-killed hemolytic streptococci (Strain AB(13)). 2. Local inflammation with or without necrosis was observed in the liver and in the spleen of most of the rabbits. Injections into...

Breast cancer radioimmunoscintigraphy targeting HER2/neu expression is a growing fieldof work in nuclear medicine research. In this study, trastuzumab was successively labeledwith [67Ga] GaCl3 after conjugation with DOTA-NHS-ester.The conjugates were purified by molecular filtration, the average number ofDOTA conjugated per mAb was calculated and total concentration was determined byspectrophot...

introduction to define the clinical features, biochemical and histological findings and outcome of three forms of autoimmune hepatitis.   materials and methods in a cross sectional study between november 2001 to january 2008 in tehran and mashhad university of medical sciences, 61 children who diagnosed as aih (40 girls and 21 boys) have been analyzed for their clinical, serological, and histol...

Introduction: Diabetes mellitus, as a chronic metabolic disease, is associated with a wide range of kidney and liver disorders. The goal of this study was to indicate the effects of selenium nanoparticles on the function of kidney and liver enzymes in stereptozocin induced diabetic rats. Methods: In this study, 35 male wistar rats were divided into five groups (n=7): control, diabetic control a...
