from the right side of the rat were used to determine the radioactivity contained within the mammary teat, fat pad, and vascular areas, while those from the left side were separated into parenchymal cell and fat cell fractions. The intracellular lipid of the parenchymal cells was extracted and quantitated. Although the pattern of carcinogen uptake and clearance by the parenchymal cell intracell...

Magnetic resonance imaging (MRI) plays an important role in the assessment of chronic pancreatitis. By standard MRI techniques, decreased parenchymal signal on T1-weighted fat-suppressed images and delayed gradual enhancement on serial contrast enhanced images represent fibrotic changes caused by chronic inflammation. Magnetic resonance cholangiopancreaticography (MRCP) can reveal ductal change...

conclusions ferric chloride is an effective haemostatic agent in controlling liver parenchymal tissue hemorrhage in an animal model. results the hemostasis time of ferric chloride concentration groups was significantly less than that of the control group (p value < 0.001). the pathologic examination showed the highest frequency of low grade inflammation based on the defined pathological grading...

Seventy nine pancreatic specimens were obtained from patients treated with pancreatic resection for acute necrotising pancreatitis. The necrotising process had started in the periphery of the gland, so that eight of seventy nine cases contained peripancreatic (mainly fat) necrosis only without any parenchymal necrosis. Peripheral parenchymal necrosis was characterised by a severe inflammatory r...

BACKGROUND AND PURPOSE Quantitative MR imaging allows segmentation of different tissue types and automatic calculation of intracranial volume, CSF volume, and brain parenchymal fraction. Brain parenchymal fraction is calculated as (intracranial volume - CSF volume) / intracranial volume. The purpose of this study was to evaluate whether the automatic calculation of intracranial CSF volume or br...

The course of radiation-induced sialadenitis in 58 cases in the salivary gland registry (Institute for Pathology of the University of Hamburg 1965-1987) was subjected to pathohistological and immunohistochemical analysis. The pathohistological changes may be classified by severity into 3 stages. Stage I is characterized by mild inflammatory interstitial changes and moderate atrophy of individua...

 Abstract Background: Screening for patients at risk of renal scarring is a challenge in children with acute pyelonephritis (APN). Diuretic Tc-99m mercaptoacetyltriglycine (MAG3) scintigraphy with zero time injection of furosemide (MAG3-F0) was observed to display focal parenchymal disorders. The advantages of MAG3 include: lower radiation dose and short duration of the test. The aim of this st...

OBJECTIVES To detect and localize MRI signal changes prior to the parenchymal contrast enhancement that classically defines the radiologic onset of the developing white matter lesion in multiple sclerosis (MS). METHODS We reviewed 308 high-resolution (≤1 mm(3) voxels) MRI scans at 3T and 7T in 29 patients with active MS. The presence of pre-parenchymal enhancement abnormalities before the app...
