Magnesium Causes Nitric Oxide Independent Coronary Artery Vasodilation in Humans Heart: First Published As 10.1136/Hrt.86.2.212 on 1 August 2001
212 Heart 2001;86:212–216 Magnesium causes nitric oxide independent coronary artery vasodilation in humans Heart: first published as 10.1136/hrt.86.2.212 on 1 August 2001. Downloaded from H Teragawa, M Kato, T Yamagata, H Matsuura, G Kajiyama Abstract Objective—To determine how magnesium aVects human coronary arteries and whether endothe- lium derived nitric oxide (EDNO) is involved in the coronary arterial response to magnesium. Design—Quantitative coronary angiography and Doppler flow velocity measurements were used to determine the eVects of the nitric oxide synthase inhibitor NG-monomethyl-L-arginine (L-NMMA) on magnesium induced dilation of the epicardial and resistance coronary arteries. Setting—Hiroshima University Hospital a tertiary cardiology centre. Patients—17 patients with angiographically normal coronary arteries. Interventions—Magnesium sulfate (MgSO4) (0.02 mmol/min and 0.2 mmol/min) was infused for two minutes into the left coronary ostium before and after intracoronary infusion of L-NMMA. Main outcome measures—Diameter of the proximal and distal segments of the epicardial cor- onary arteries and coronary blood flow. Results—At a dose of 0.02 mmol/min, MgSO4 did not aVect the coronary arteries. At a dose of 0.2 mmol/min, MgSO4 caused coronary artery dilation (mean (SEM) proximal diameter 3.00 (0.09) to 3.11 (0.09) mm; distal 1.64 (0.06) to 1.77 (0.07) mm) and increased coronary blood flow (79.3 (7.5) to 101.4 (9.9) ml/min, p < 0.001 v baseline for all). MgSO4 increased the changes in these parameters after the infusion of L-NMMA (p < 0.001 v baseline). -

This Fact Sheet Provides Information to Patients with Eczema and Their Carers. About Topical Corticosteroids How to Apply Topic
This fact sheet provides information to patients with eczema and their carers. About topical corticosteroids You or your child’s doctor has prescribed a topical corticosteroid for the treatment of eczema. For treating eczema, corticosteroids are usually prepared in a cream or ointment and are applied topically (directly onto the skin). Topical corticosteroids work by reducing inflammation and helping to control an over-reactive response of the immune system at the site of eczema. They also tighten blood vessels, making less blood flow to the surface of the skin. Together, these effects help to manage the symptoms of eczema. There is a range of steroids that can be used to treat eczema, each with different strengths (potencies). On the next page, the potencies of some common steroids are shown, as well as the concentration that they are usually used in cream or ointment preparations. Using a moisturiser along with a steroid cream does not reduce the effect of the steroid. There are many misconceptions about the side effects of topical corticosteroids. However these treatments are very safe and patients are encouraged to follow the treatment regimen as advised by their doctor. How to apply topical corticosteroids How often should I apply? How much should I apply? Apply 1–2 times each day to the affected area Enough cream should be used so that the of skin according to your doctor’s instructions. entire affected area is covered. The cream can then be rubbed or massaged into the Once the steroid cream has been applied, inflamed skin. moisturisers can be used straight away if needed. -

Dilantin (Phenytoin Sodium) Extended Oral Capsule Three Times Daily and the Dosage Then Adjusted to Suit Individual Requirements
Dilantin® (Phenytoin Sodium) 100 mg Extended Oral Capsule DESCRIPTION Phenytoin sodium is an antiepileptic drug. Phenytoin sodium is related to the barbiturates in chemical structure, but has a five-membered ring. The chemical name is sodium 5,5-diphenyl-2, 4-imidazolidinedione, having the following structural formula: Each Dilantin— 100 mg Extended Oral Capsule—contains 100 mg phenytoin sodium. Also contains lactose monohydrate, NF; confectioner’s sugar, NF; talc, USP; and magnesium stearate, NF. The capsule body contains titanium dioxide, USP and gelatin, NF. The capsule cap contains FD&C red No. 28; FD&C yellow No. 6; and gelatin NF. Product in vivo performance is characterized by a slow and extended rate of absorption with peak blood concentrations expected in 4 to 12 hours as contrasted to Prompt Phenytoin Sodium Capsules, USP with a rapid rate of absorption with peak blood concentration expected in 1½ to 3 hours. CLINICAL PHARMACOLOGY Phenytoin is an antiepileptic drug which can be used in the treatment of epilepsy. The primary site of action appears to be the motor cortex where spread of seizure activity is inhibited. Possibly by promoting sodium efflux from neurons, phenytoin tends to stabilize the threshold against hyperexcitability caused by excessive stimulation or environmental changes capable of reducing membrane sodium gradient. This includes the reduction of posttetanic potentiation at synapses. Loss of posttetanic potentiation prevents cortical seizure foci from detonating adjacent cortical areas. Phenytoin reduces the maximal activity of brain stem centers responsible for the tonic phase of tonic-clonic (grand mal) seizures. The plasma half-life in man after oral administration of phenytoin averages 22 hours, with a range of 7 to 42 hours. -

Prednisolone Versus Dexamethasone for Croup: a Randomized Controlled Trial Colin M
Prednisolone Versus Dexamethasone for Croup: a Randomized Controlled Trial Colin M. Parker, MBChB, DCH, MRCPCH, FACEM,a,b Matthew N. Cooper, BCA, BSc, PhDc OBJECTIVES: The use of either prednisolone or low-dose dexamethasone in the treatment of abstract childhood croup lacks a rigorous evidence base despite widespread use. In this study, we compare dexamethasone at 0.6 mg/kg with both low-dose dexamethasone at 0.15 mg/kg and prednisolone at 1 mg/kg. METHODS: Prospective, double-blind, noninferiority randomized controlled trial based in 1 tertiary pediatric emergency department and 1 urban district emergency department in Perth, Western Australia. Inclusions were age .6 months, maximum weight 20 kg, contactable by telephone, and English-speaking caregivers. Exclusion criteria were known prednisolone or dexamethasone allergy, immunosuppressive disease or treatment, steroid therapy or enrollment in the study within the previous 14 days, and a high clinical suspicion of an alternative diagnosis. A total of 1252 participants were enrolled and randomly assigned to receive dexamethasone (0.6 mg/kg; n = 410), low-dose dexamethasone (0.15 mg/kg; n = 410), or prednisolone (1 mg/kg; n = 411). Primary outcome measures included Westley Croup Score 1-hour after treatment and unscheduled medical re-attendance during the 7 days after treatment. RESULTS: Mean Westley Croup Score at baseline was 1.4 for dexamethasone, 1.5 for low-dose dexamethasone, and 1.5 for prednisolone. Adjusted difference in scores at 1 hour, compared with dexamethasone, was 0.03 (95% confidence interval 20.09 to 0.15) for low-dose dexamethasone and 0.05 (95% confidence interval 20.07 to 0.17) for prednisolone. -

Several programs exist to control their numbers through lethal removal, using tools such as baiting with toxins. Adult male cats are especially difficult to control. We hypothesized that one way to capture these male cats is to lure them using female cats. As female cats are seasonal breeders, a method is needed to artificially induce reproductive (estrous) behavior so that they could be used for this purpose year-round (i.e., regardless of season).
