A single subcutaneous injection of 3.3'-methyliminobis-(N-methylpropylamine) caused edema and necrosis in the hypothalamus and medulla oblongata of rats, mice, and gerbils. Most other aliphatic triamines were ineffective. The lesions were very similar in character and distribution to those caused by
The administration of an aliphatic triamine, 3,3'-methylimino-bis-(N-methylpropylamine), was used to produce non-necrotizing lesions in the hypothalamus and medulla oblongata of rats. The distribution of the lesions in the hypothalamus was similar to that produced by goldthioglucose, and consisted
Intratracheal administration of lipopolysaccharide (LPS) in animals is a commonly used model of acute lung injury, characterized by increased alveolar-capillary membrane permeability causing protein-rich edema, inflammation, deterioration of lung mechanical function and impaired gas exchange.
To evaluate the incidence, quantity, and presentation of intra- and extraosseous edema accompanying benign and malignant primary bone lesions, the magnetic resonance (MR) studies of 63 consecutive patients with histologically proven primary bone tumors were reviewed. MR scans were assessed for the
Tyramine induces coma in phenelzine-treated dogs. Development of coma in these animals is associated with brain edema, abnormal brain scans of Tc-99m-diethylene-triamine-penta-acetic acid (Tc-99m-DTPA), and elevated levels of CSF catecholamines. We found that the intravenous administration of 6-7
By optimizing the inversion time of a 3D inversion-recovery turbo spin-echo sequence at 3T, we obtained separate images of endolymphatic and perilymphatic space 24 hours after intratympanic administration of gadolinium contrast material. In patients with Ménière disease, endolymphatic hydrops were
BACKGROUND
To evaluate whether the Modification of Diet in Renal Disease (MDRD) equations could be applied accurately to Chinese patients with chronic kidney disease (CKD), glomerular filtration rates (GFRs) estimated by using MDRD equation 7 (7GFR), the abbreviated MDRD equation (aGFR), and the
Gadolinium 1,4,7,10-tetraazacyclododecane-N,N',N",N"'-tetraacetic acid (Gd-DOTA) is the first of a new class of macrocyclic paramagnetic magnetic resonance (MR) contrast agents (gadolinium cryptelates) to be used in clinical practice. Gadolinium-DOTA possesses relaxation properties similar to those
BACKGROUND
The patient population receiving long-term oxygen therapy has increased with the rising morbidity of COPD. Although high-dose oxygen induces pulmonary edema and interstitial fibrosis, potential lung injury caused by long-term exposure to low-dose oxygen has not been fully analyzed. This
Postoperative magnetic resonance imaging findings related to the vestibulocochlear and facial nerves within the internal auditory canal were analyzed in acoustic neurinomas. T1- and proton-weighted magnetic resonance images showed that the vestibulocochlear nerves distal to the internal auditory
A 2-year-old boy with severe head trauma was diagnosed brain dead according to the 2011 Pediatric Guidelines. Computed tomographic (CT) scan showed massive cerebral edema with herniation. Intracranial pressures were extremely high, with cerebral perfusion pressures around 0 for several hours. An
The case of a twenty-year-old male with orbital chondrosarcoma is reported. He visited National Defense Medical College Hospital because of reduced vision in the right eye since two months previously. His corrected visual acuity was 8/20 in the right eye and 20/20 in the left eye. Fifteen degrees
BACKGROUND
Cardiac involvement is an important prognostic factor in patients with sarcoidosis. In this study, we evaluated the usefulness of gadolinium-DTPA (diethylene triamine pentaacetic acid)-enhanced magnetic resonance imaging (Gd-MRI) for diagnosing cardiac sarcoidosis and evaluating the
We performed a preliminary study to assess the usefulness of Vitamin A binding protein (VABP) as a gamma-camera marker for capillary endothelial permeability. We used a guinea pig model of endotoxin (LPS) induced acute lung injury. We calculated the concentration ratio of either 125I-albumin or
Local drug delivery techniques, such as convention-enhanced delivery (CED), are promising novel strategies for delivering therapeutic agents otherwise limited by systemic toxicity and blood-brain-barrier restrictions. CED uses positive pressure to deliver infusate homogeneously into interstitial
