It has become increasingly apparent in recent years that certain structural alterations of corticosteroids cause an increased biological potency of the resultant steroid (2). A number of chemical and microbiological alteration products of hydrocortisone exhibit enhanced anti-inflammatory potency coupled with unchanged or depressed mineralocorticoid activity (2, 3). As a result, steroids bearing...

Objective- To determine the effects of the Hydrocortisone on in vitro growth of fibrobla sts isolatedfrom the distal  aspects of the horses limbs.Design- Experimental in vitro study.Animals- A total of 4 Caspian miniature and 4 mixed thoroughbred horses. Procedures- Under generalanesthesia and aseptic condition, a full thickness of skin incision was created on the lateral aspects of themetacarp...

Introduction: Phonophoresis is the use of ultrasound to enhancing cellular drug delivery through the skin. In this study the effect of clobethasole and hydrocortisone ointments phonophoresis on pain, knee osteoarthritis and some other symptoms was studied. Methods: An experimental single blind randomized clinical trial (RCT) was used. An available sampling technique was used for selection o...

CONTEXT The role of stress-dose hydrocortisone in the management of trauma patients is currently unknown. OBJECTIVE To test the efficacy of hydrocortisone therapy in trauma patients. DESIGN, SETTING, AND PATIENTS Multicenter, randomized, double-blind, placebo-controlled HYPOLYTE (Hydrocortisone Polytraumatise) study. From November 2006 to August 2009, 150 patients with severe trauma were in...

This study evaluated the in vitro potential of cocoa pod husk (CPH) pectin as a carrier for chronodelivery of hydrocortisone intended for adrenal insufficiency. FTIR studies found no drug-CPH pectin interactions, and chemometric analysis showed that pure hydrocortisone bears closer similarity to hydrocortisone in hot water soluble pectin (HWSP) than hydrocortisone in citric acid soluble pectin ...

Glucocorticoid replacement therapy needs to be tailored to individual patient's requirements in order to avoid risk of over or under medication. We measured bone mineral density (BMD) of lumbar spine using dual X-ray absorptiometory in 10 patients with Addison's disease and 5 patients with isolated ACTH deficiency receiving glucocorticoid replacement therapy. We also examined the effect of gluc...

The objective of this study was to establish optimal conditions for the primary culture of pig preadipocytes. We cultured pig preadipocytes for 10 d and studied the effects of insulin, hydrocortisone, and triiodothyronine (T3) added to serum-free basal medium on differentiation and gene expression of lipoprotein lipase an early marker, and adipsin, a late marker of preadipocyte differentiation....

The effects of hydrocortisone, corticosterone, and pituitary adrenocorticotropin on antibody production were studied immunochemically in rabbits. Hydrocortisone in doses as low as 2.5 mg. per day (approximately 1.0 mg. per kg. per day) markedly depressed antibody production whereas corticosterone in doses four times as large exerted no significant effect. Corticotropin in doses of 15 units dail...

INTRODUCTION Low-dose hydrocortisone treatment is widely accepted therapy for the treatment of vasopressor-dependent septic shock. The question of whether corticosteroids should be given to septic shock patients by continuous or by bolus infusion is still unanswered. Hydrocortisone induces hyperglycemia and it is possible that continuous hydrocortisone infusion would reduce the fluctuations in ...

In the pulmonary vasculature, cGMP levels are regulated by soluble guanylate cyclase (sGC) and phosphodiesterase 5 (PDE5). We previously reported that lambs with persistent pulmonary hypertension of the newborn (PPHN) demonstrate increased reactive oxygen species (ROS) and altered sGC and PDE5 activity, with resultant decreased cGMP. The objective of this study was to evaluate the effects of hy...
