Experimental septic arthritis was induced in the radiocarpal joint of 18 donkeys by intra-articular injection of Staphylococcus aureus (3-4X10(6) CFU). The inoculated animals were divided into three groups (6 donkeys in each group). The arthroscopic examination was carried out before induction of septic carpitis and 3 days (group I), 14 days (group II), and 28 days (group III) after induction o...

BACKGROUND We report necrotizing scleritis as a serious complication of a cosmetic eye whitening procedure that involves the use of intraoperative and postoperative topical mitomycin C. FINDINGS This is a single case report. A 59-year-old Caucasian male with a history of blepharitis status post uncomplicated LASIK refractive surgery reported chronic conjunctival hyperemia for 15 years prior t...

Background Background More than half of the cardiac stress tests require pharmacologic vasodilators for induction of hyperemia to assess myocardial perfusion, but carry the potential for side effects and are contraindicated in many patients considered for testing. We evaluated the feasibility of a non-invasive and safe stress-testing paradigm using a precisely targeted partial pressure of arter...

Background Adenosine has traditionally been utilized for coronary hyperemia during myocardial perfusion assessment in adults, however regadenoson has recently become more popular [1]. With improved survival of congenital heart disease (CHD), and increased diagnosis of acquired heart disease (AHD), there’s an increasing need for assessment of myocardial perfusion in pediatrics [2]. Only dipyrida...

UNLABELLED In this case report, we present a 70 year old female patient who had recieved Leech therapy (hirudotherapy) on her leg without informing referring physician. In dynamic bone scintigraphy there was increased perfusion and hyperemia in her left ankle and leg, also in late static images moderate increased uptake was seen in soft tissue region and at the fracture site of ankle. We learne...

This study was undertaken to determine whether the reactive hyperemia response following ischemia in spinal cord injured (SCI) individuals is different from that which occurs in able-bodied (AB) individuals. The reactive hyperemia response was produced by applying a pressure of 150 mmHg for 300 s, 600 s, and 900 s to the skin over the greater trochanter in 10 SCI and 10 AB subjects using a comp...

1. The S, R, and R(n) variants of the Shiga bacillus are equally toxic. 2. The effect of the toxin upon rabbits is the same, whether it is derived from filtrates of broth cultures (3 to 6 days old), or is obtained by autolysis of the killed bacteria, grown on agar surface. Rabbits show in both cases prostration, loss in weight, paralysis, and diarrhea. 3. When the toxin is heated to 80 degrees ...

Intraperitoneal injection of human chorionic gonadotropin in the rat induces a dose-dependent frequency of ovarian hyperemia. The occurrence of such hyperemia can be inhibited by pre-injection (3 hours) of antisera from rabbits immunized with gonadotropin extracts. It is demonstrated that the retained capacity of gonadotropin to induce hyperemia following antisera injections is greater when the...

The purpose of the study was to investigate the potential of magnetic resonance imaging (MRI) to assess transmural differences in myocardial perfusion. Contrast-enhanced MRI was performed at rest and during hyperemia in a dog model and in 22 patients with single-vessel coronary artery disease. From MR signal intensity-versus-time curves, three perfusion parameters were derived: maximum myocardi...

In the brain, neuronal activation triggers a local increase in cerebral blood flow, a response named functional hyperemia. The extent to which functional hyperemia faithfully reports brain activation, spatially or temporally, remains a matter of debate. Here, we used the olfactory bulb glomerulus as a neurovascular model and two-photon microscopy imaging to investigate the correlation between c...
