Vascular endothelial growth factor (VEGF) is stated to be a possible promoter of the development and the severity of ovarian hyperstimulation syndrome (OHSS). The secretion of VEGF in granulosa cells seems to be human chorionic gonadotrophin (HCG) dependent. In this prospective study, the data of 10 patients suffering from severe OHSS with ascites and pleural effusions (haematocrit, fluid balan...

The majority of patients with sickle-cell anaemia live in the underdeveloped nations where endemic parasitic diseases are prevalent and this may exacerbate the severity of steady-state anaemia in infected patients. We studied the impact of intestinal parasites on haematological parameters of sickle-cell anaemia patients aged 18-35 years in Kano, Nigeria. Of 100 patients studied, 27 were found t...

Platelet aggregation was studied in citrated whole blood by an electrical impedance method. Blood samples from normal volunteers were studied with the aim of finding a suitable method for the routine study of samples from patients. An erratic tracing and low maximum aggregation were seen in samples with a high normal haematocrit. Optimal aggregation was seen when blood was diluted to a haematoc...

The physiological effects of acute stress (induced by an intraperitoneal injection) on the haematocrit, haemoglobin, serum cortisol and glucose, haemagglutinins and lysozyme were investigated in juvenile sea bass Dicentrarchus labrax. A total of 40 fish were subjected to an intraperitoneal injection. Eight fish were sampled at 0, 2, 4, 24 and 48 h after acute stress and compared to unstressed f...

The aim of this study was to investigate the relation between erythrocyte parameters of piglets and their mortality during parturition. Erythrocyte count, haematocrit volume, blood haemoglobin concentration, mean cell volume (MCV), mean cell haemoglobin (MCH) and mean cell haemoglobin concentration (MCHC) were determined in 80 live-born and 109 stillborn piglets. In both live-born and stillborn...

BACKGROUND Iron-deficiency anemia during pregnancy is still common in developed countries. The aim of this study was to evaluate the influence of maternal anemia on the infant's iron status at 9 months of age in Moncton, NB. METHODS Mothers giving birth between April 1998 and February 1999 were selected from medical records. A letter was sent to invite them to participate. In total, 75 mother...

Juveniles of L. rohita were exposed to sublethal levels of nitrite (0.02, 0.1 and 0.4 mg/l) for 2, 24, 48 and 96 hr. The time of exposure at individual concentrations of nitrite did not show any significant difference in haemoglobin, cortisol, chloride and lactic acid. Haematocrit showed significant reduction with increasing concentration of nitrite irrespective of duration of exposure. Fishes ...

In vivo experiments were carried out to determine the effect of forced activity on circulating catecholamine levels, haematocrit, and the pH and water content of erythrocytes in the toad, Bufo marinus. In addition, the effect of the beta-adrenergic agonist isoproterenol on erythrocyte pH and water content was examined in vitro. Forced activity caused a significant decrease in both whole blood a...
