SIR,-We read with interest the leading article by Dr John Rees on the treatment of pulmonary hypertension in patients with chronic bronchitis and emphysema (24 November, p 1398). An appreciable, but unknown, number of patients with hypoxia also develop polycythaemia, and in these cases reducing packed cell volume may help to ameliorate pulmonary hypertension. Blood viscosity rises -exponentiall...

background: it is not clear whether the use of volumetric peristaltic infusion pumps, affect the quality of the erythrocytes during packed cell transfusion or not. in the present study in vitro quality of red blood cells was assessed after using this type of infusion pumps in a prospective study. materials and methods: in this study 60 units of packed red cells were examined before and after pa...

This study was done to determine whether high or low dose of anti-snake venom (ASV) is better in coagulopathy in victims of envenoming by vipers. This retrospective study was conducted on the 154 patients (Mean age ± SD, Range) of viper snake bites who were referred to the emergency ward of Razi Hospital, Ahvaz, Iran over 2 years period (2004 - 2006). According to the treatment dosage the patie...

BACKGROUND Sickle cell disease is a genetic disorder of hemoglobin causing myriad of pathology including anemia. The purpose of this study was to evaluate the baseline values of steady state hemoglobin and packed cell volume as a guide to managing the early recognition of hemolytic crises in sickle cell anemia. METHODS A cross-sectional study was conducted among the sickle cell patients atten...

The aim of the present study is to evaluate the antitumor effect and antioxidant role of Mucuna pruriens (Family: Fabaceae) against EAC bearing Swiss albino mice. The effect of methanol extract of Mucuna pruriens (MEMP) on tumor growth and hosts survival time was studied by the following parameters: tu-mor volume, packed cell volume, viable and non-viable cell count and life span of the host. M...

Packed open-cell foams are proposed as an alternative to standard packed bed configuration commonly adopted for the adsorption columns of a temperature swing process. In this contribution, heat transfer in column with foam is investigated by experimental and modeling analysis, comparison bed. The introduction allows more rapid transitions substantial reduction gradients within impact enhancemen...

Objective: Based on the potential clinical and management significance of selected hematological serum biochemistry parameters, study aimed to establish reference ranges for juvenile Heterotis niloticus  (African bonytongue fish) a fish with significant aquaculture in Africa. Design procedure: Hematology biochemical were determined blood samples obtained from 243 healthy sampled three location...

Kinetochores are multi-protein megadalton assemblies that are required for attachment of microtubules to centromeres and, in turn, the segregation of chromosomes in mitosis. Kinetochore assembly is a cell cycle regulated multi-step process. The initial step occurs during interphase and involves loading of the 15-subunit constitutive centromere associated complex (CCAN), which contains a 5-subun...

BACKGROUND The technique of deep hypothermic circulatory arrest (DHCA) for cardiothoracic surgery is associated with increased risk for perioperative blood loss and renal dysfunction. Although aprotinin, a serine protease inhibitor, reduces blood loss in patients undergoing cardiopulmonary bypass, its use has been limited in the setting of DHCA because of concerns regarding aprotinin-induced re...

PURPOSE To investigate the structural remodeling in gap junctions associated with cholesterol redistribution during fiber cell maturation in the adult chicken lens. We also evaluated the hypothesis that the cleavage of the COOH-terminus of chick Cx50 (formerly Cx45.6) during fiber cell maturation would affect the gap junction remodeling. METHODS Freeze-fracture TEM and filipin cytochemistry w...
