Keloid treatment: is there a role for acellular human dermis (Alloderm)?

BACKGROUND: Keloid management is faced with high recurrence rates. Keloid fibroblasts lack the normal negative feedback mechanism resulting in an exuberant scar formation. Alloderm doesn't undergo the same proliferative process as keloidal scar…

Anti-edema action of thyroid hormone in MCAO model of ischemic brain stroke: Possible association with AQP4 modulation.

The use of neuroprotective strategies to mitigate the fatal consequences of ischemic brain stroke is a focus of robust research activity. We have previously demonstrated that thyroid hormone (T3; 3,3',5-triiodo-l-thyronine) possesses neuroprotective…

Functional outcome after anal sphincter injury and treatment with mesenchymal stem cells.

This research demonstrates the regenerative effects of mesenchymal stem cells (MSCs) on the injured anal sphincter by comparing anal sphincter pressures following intramuscular and serial intravascular MSC infusion in a rat model of anal sphincter…

CONTINUOUS-INFUSION OF PYRIDOSTIGMINE IN THE MANAGEMENT OF MYASTHENIC CRISIS

Secure cranial-mount intrathecal cannulation - a spinal administration technique in the rat.

In order to identify an acute spinally mediated pharmacological effect of a bioactive substance, without incurring untoward supraspinal effects, it is necessary to administer the agent locally onto the spinal cord. The procedure delineated herein…

Scopolamine-physostigmine combination does not substitute for nicotine.

1. Male Sprague-Dawley rats were trained to discriminate 0.4 mg/kg nicotine subcutaneously administered from its saline vehicle in a food-motivated operant discrimination task. Once trained, the discriminative performance was observed to be…

Temporal differences in behavioral effect of fenfluramine and norfenfluramine.

Ten male rats were trained to discriminate the anorectic drug d,l-fenfluramine (2.0 mg/kg intraperitoneally administered) from its vehicle using a food-reinforced (fixed-ratio 10 schedule) two-lever operant task. Once learned, the fenfluramine…

Conditioned place aversion produced by dopamine release inhibition.

CGS 10746B, a dopamine release inhibitor with properties similar to the atypical antipsychotic clozapine, was assessed as to its behavioral properties using spontaneous locomotor activity and the conditioned place preference test. Rats conditioned…

Dopaminergic mediation of the stimulant generalization of nicotine.

1. Experiments were conducted to investigate if the psychostimulant cathinone, like d-amphetamine, would produce generalization of the discriminative stimulus effects of nicotine. 2. Rats were trained to discriminate either 0.8 mg/kg cathinone from…

Direct microinjection of cathinone into the rat brain produces discriminative stimuli.

Rats were trained to discriminate IP administration of 800 micrograms/kg cathinone using a food-motivated, two-lever discrimination procedure. Following training, 800 micrograms/kg cathinone discrimination was produced (generalized) by lower…

Pharmacokinetics of imipenem in serum and skin window fluid in healthy adults after intramuscular or intravenous administration.

The pharmacokinetic profiles of imipenem after intramuscular (i.m.) and intravenous injections were examined in adult volunteers. Levels of imipenem in serum after i.m. injection of a microcrystalline suspension of imipenem-cilastatin (500 mg each)…
