Aqueous Extract and Its Fraction Prevents Blood Coagulation by Specifically Inhibiting the Intrinsic Coagulation Pathway: An in vitro Study.

Background: Currently, cardiovascular disorders are the primary cause of mortality in the world and constitute a serious medical problem. Blood coagulation is an essential process to prevent excessive blood loss through injured blood vessels; however, abnormal blood clotting in the blood vessels can result in fatal cardiovascular disorders. This study investigated the in vitro anticoagulant activity of crude extract and its fractions and their erythrocyte membrane stabilizing activity.

Biliary Strictures Are Associated With Both Early and Late Hepatic Artery Stenosis.

Background: Hepatic artery stenosis (HAS) following liver transplantation results in hypoperfusion and ischemic damage to the biliary tree. This study aimed to investigate how vascular intervention, liver function test derangement, and time point of HAS onset influence biliary complications.

Methods: A single-center retrospective study of adult patients that underwent primary liver transplantation.

Seroprevalence of transfusion-transmissible infections among blood donors at National Blood Transfusion Service, Eritrea: a seven-year retrospective study.

Background: Blood transfusion is associated with several risks particularly exposure to blood transfusion-transmissible infections (TTI), including: Hepatitis B virus (HBV), Hepatitis C virus (HCV), Human immunodeficiency virus (HIV) and Syphilis, among others. The threat posed by these blood-borne pathogens is disproportionately high in Sub-Saharan Africa (SSA). This fact underscores the need for continuous surveillance of TTIs in the region.

Establishment of hematological reference intervals for healthy adults in Asmara.

Objectives: Clinical laboratory reference intervals used in a specific area should be derived from the local population as they are influenced by many factors. The purpose of this quantitative cross sectional study was to establish hematological reference intervals for healthy adults in Asmara and to determine whether the currently used reference interval do represent the adult population in the city. In addition, the established reference intervals were compared to findings from similar studies conducted in selected countries in Africa.

Histopathologic features of oral submucous fibrosis: a study of 35 biopsy specimens.

Objectives: This study was carried out principally to confirm the diagnosis of Oral Submucous Fibrosis, to provide a more detailed description of the Histopathological changes occurring in OSMF and to look for and record any new finding which might be detected. For this reason only previously untreated cases were selected for biopsy.

Setting: Patients reporting at Liaquat University Hospital, Dental Out Patient Department, Hyderabad, Sindh, Pakistan.

Emphysematous gastritis: a case report and a review of literature.

Introduction: Gas is rarely found within the viscera outside the lumen of the gastrointestinal tract. Emphysematous gastritis is a rare form of infection of the stomach wall by gas producing organisms.

Clinical Picture: A 45-year-old Chinese lady underwent hepatectomy for hepatocellular carcinoma.
