CONTEXT Mobile water within the bone marrow is a physiological phenomenon that is identifiable on magnetic resonance (MR) imaging, and signal changes can result from blood pooling, reactive hyperemia, edema, and microfracture. When these MR lesions are associated with an acute traumatic event, the findings are referred to as bone bruises and so represent a unique manifestation of injury. This r...

An alternative theory is proposed to explain the brain edema and hemorrhage that may occur after resection of high-flow intracerebral arteriovenous malformations (AVM's). This theory, termed "occlusive hyperemia," is based on a retrospective analysis of operative dictations along with postoperative imaging studies (191 angiograms and 273 computerized tomography scans) in 295 cases of intracereb...

background: besides of transmitting several diseases to animals, and tick paralysis, ornithodoros lahorensis induce skin lesions. this experiment was done to determine histopathological features of adult o. lahorensis bite on rat. methods: in this investigation adult male rats were infested with o. lahorensis ticks. animals were divided into two groups and euthanized two days and two weeks afte...

The mounting gradient of permeability along the small vessels of the corium is essentially unaltered by active hyperemia produced by heat, cold, or light. Only when the vascular walls are so damaged that rapid leakage ensues, as shown by the development of edema, does the permeability of the capillary web as a whole approximate that of the venules. It is plain that the normal gradient of vascul...

Objective- The current study was conducted to evaluate changes in the urinary bladder structure and leukocyte profile as an important index of the systemic inflammation response for two different types of spinal cord injury (SCI) in a rat model. Design- Experimental Study.Animals- Forty adult healthy female Sprague-Dawley rats.<br /...

Acetaminophen (APAP) poisoning is the most common drug intoxication, which often leads to acute liver failure (ALF). In this study, the effects of different doses of APAP on aminotransferases (AST and ALT) and liver pathological lesions were assessed in young rats. 32 male albino Wistar rats were randomly selected and divided into eight groups. In case groups, three groups after one hour, and 3...

S CHMITT AND MEYERS' SHOWED IN 1957 that the acute pulmonary edema that follows vagal section is associated with a marked decrease in sympathetic inflow to the lung. It has long been known, on the other hand, that certain forms of acute pulmonary edema are associated with a marked increase in the organism's total level of sympathetic activity.2 Pursuing this dichot-omy as a possible taxonomic p...

Canaliculitis is an uncommon condition of the lacrimal canaliculi. The presentation usually unilateral and runs with epiphora, hyperemia, edema, pain, discharge secretion by point. diagnosis clinical since its findings are quite typical. Surgical treatment canaliculotomy has been described as most effective. should be considered in recurrent cases conjunctivitis ophthalmologist aware signs for ...

Background: Systemic lupus erythematosus (SLE) is an autoimmune disease in which cutaneous lesions occur in 72%-85% of patients. Objective: This study was conducted to determine the pattern and incidence of skin lesions in SLE patients in Ahwaz. Patients and Methods: Thirty patients with SLE fulfilling the clinical and laboratory criteria of the American Rheumatism Association who were admitted...

In the present study, a sequential observation of the gastric lesions or ulcers in rats weighing from 100 g was made with an endoscope. It was found that bleeding, edema, hyperemia, fur of ulcer and convergences of the mucosal folds in the stomach could be observed in rats with a SES-1717S (phi = 1.7 mm) or SES-2217S (phi = 2.2 mm) endoscope. Furthermore, we have devised a method which we named...
