PURPOSE The endothelins are potent vasoactive peptides. This study was performed to characterize the in vivo effects of the endothelin peptides on the retinal circulation in nondiabetic and diabetic rats. METHODS The video fluorescein angiography methodology was used to quantitate retinal hemodynamic responses to endothelin-1 (ET-1) and endothelin-3 (ET-3) in rats. A total of 99 rats were use...

Abstract Background Dexamethasone is a potent corticosteroid when comes to effectively preventing postoperative nausea and vomiting (PONV). However, some studies have documented its association with hyperglycemia. In our study, we compared the effect of single-dose dexamethasone (8 mg) on blood glucose concentrations among diabetics non-diabetic patients who received spinal anesthesia for elect...

background: results of various studies suggest that the hypertrophic and keloid scars are highly prevalent in the general population and are irritating both physically and mentally. objective: considering the variety of existing therapies, intense pulsed light (ipl) method along with corticosteroid injection was evaluated in treating these scars. materials and methods: 86 subjects were included...

BACKGROUND Intralesional injection of corticosteroids is an effective treatment for tumors of the head and neck. Complications are rare but include permanent loss of vision. We designed a study to investigate the mechanism for this complication. METHODS Three fellowship-trained pediatric ophthalmologists participated in the study in a nonmasked fashion. Four patients received 5 separate treat...

The activity of alanine-cr-ketoglutarate transaminase (n-alanine :2-oxoglutarate aminotransferase, EC 2.6.1.2) is increased markedly in the livers of diabetic or fasted rats (1). The induction of this enzyme also occurs when either intact or adrenalectomized rats are fed diets high in protein or given corticosteroid injections (24). The adaptive response of this enzyme in glucocorticoid-sensiti...

UNLABELLED There is conflicting evidence about the benefit of using corticosteroid in periarticular injections for pain relief after total knee arthroplasty (TKA). We carried out a double-blinded, randomised controlled trial to assess the efficacy of using corticosteroid in a periarticular injection to control pain after TKA. A total of 77 patients, 67 women and ten men, with a mean age of 74 y...

A 3-year-old boy was admitted to the emergency department with right lower limb pain, edema, and livedoid discoloration that occurred immediately after intramuscular injection of benzathine penicillin. The patient was diagnosed with Nicolau syndrome, a rare complication of intramuscular injection presumed to be related to the inadvertent intravascular injection. It was first reported following ...

OBJECTIVE To compare the effectiveness of ultrasound guided corticosteroid injection in the subacromial bursa with systemic corticosteroid injection in patients with rotator cuff disease. DESIGN Double blind randomised clinical trial. SETTING Outpatient clinic of a physical medicine and rehabilitation department in Oslo, Norway. Patients 106 patients with rotator cuff disease lasting at lea...

Objective(s) The aim of this study was to evaluate the effects of regular exercise in preventing diabetes complication in the hippocampus of streptozotocin (STZ)-induced diabetic rat. Materials and Methods A total of 48 male wistar rats were divided into four groups (control, control exercise, diabetic and diabetic exercise). Diabetes was induced by injection of single dose of STZ. Exercise ...
