It is generally accepted that the spleen contraction is a consequence of humoral stimulation but recent data suggest a role of neural mechanisms. This study tested the hypothesis that the reduction in spleen size in response to low dose epinephrine infusion is a consequence of neurally mediated unloading of baroreceptors. Continuous ultrasonic measurements of spleen volume in response to intrav...

By EFSTRATIOS S. KURTIDES, WALTER A. RAMBACH AND HOWARD L. ALT T HE INCORPORATION of tritiated thymidine by the rat spleen is an accurate and reliable index of erythropoiesis under certain well-defined experimental conditions.1 Since tritiated thymidine uptake by various tissues reflects DNA synthesis, and therefore proliferative activity, changes in the latter will be reflected by parallel cha...

PURPOSE: To clarify whether hepatic parenchymal enhancement in the hepatobiliary phase of gadolinium ethoxybenzyl diethylenetriaminepentaacetic acid (Gd-EOB-DTPA) enhanced MR imaging decreases according to the advance of the morphological severity of cirrhosis. METHODS AND MATERIALS: A total of 43 patients with cirrhosis underwent Gd-EOB-DTPA enhanced MR imaging. Contrast-enhanced images were o...

The leucocyte migration responses of patients with malignant lymphoma to an unidentified factor in Hodgkin's spleen tissue were serially studied and related to clinical progress. Initial sensitisation responses did not correlate with presenting histological or clinical status or with subsequent clinical progress. Enhancement of responses after treatment, however, was associated with good clinic...

Splenic metastasis is generally not a common clinical event. However, metastasis to the spleen from adrenal pheochromocytoma is extremely rare and has not been reported in literature. This report presents a case of a 58 year-old male patient who developed spleen-only metastases in July 2007. The patient had a previous history of left epinephroectomy for adrenal pheochromocytoma in January 2003....

Young and adult Wistar rats were submitted to total splenectomy and compared to animals not submitted to any surgical manipulation in order to evaluate the phagocytic function of spleen. The animals were infected with Escherichia coli labeled with technetium-99m and killed 20 minutes later. Liver, lung, spleen and a blood clot sample were taken. No significant differences were found in the perc...

a purification procedure of pertussis toxin (pt) from submerged culture of bordetella pertussis (b.pertussis) strain 134 using adsorption and affinity chromatography was discussed. the yield of the resulting pt was approximately 37.5mg/l of concentrated culture supernatant. the polypeptide pattern of the purified pt was investigated by sds-page and showed five bands between 11 to 26 kda using l...

diazinon is a moderately persistent organ phosphorus pesticide largely used in agriculture. thepurpose of this study was to evaluate the histopathological damages induced by diazinon in gills, kidney,spleen, and intestine tissues of rainbow trout, oncorhynchus mykiss. the fishes were exposed to sub-lethalconcentrations of diazinon (0.1 and 0.2 mg/l) for a period of 28 days. tissues analyzed by ...
