Topical corticosteroids used in various dermatological diseases are available in different potencies and different formulations. The reservoir effect of different potency corticosteroids in the stratum corneum will help the clinicians to choose an appropriate topical steroid to maximize their efficacy and safety as therapeutic agents. ⋯ It is concluded that the duration of reservoir depends on the potency of topical steroids. Higher the potency more is the duration of reservoir in stratum corneum and vice versa.

Randomized Controlled Trial
A simple cold pressure technique for the evaluation of analgesic drugs in healthy subjects.
An experimental pain model which is sensitive and reproducible would be a useful pharmacological tool both for existing and new drugs. The aim of the present study was to establish a simple and reliable method of producing experimental pain which can be used for screening of analgesic agents. ⋯ The newly developed pain model offers a stable and sensitive method for the early assessment of analgesic activity.

Acute paracetamol poisoning is an emerging problem in Sri Lanka. Management guidelines recommend ingested dose and serum paracetamol concentrations to assess the risk. Our aim was to determine the usefulness of the patient's history of an ingested dose of >150 mg/kg and paracetamol concentration obtained by a simple colorimetric method to assess risk in patients with acute paracetamol poisoning. ⋯ History of dose ingested alone greatly over-estimated the number of patients who need antidotes and it was a poor predictor of risk. Paracetamol concentrations by colorimetry are rapid and inexpensive. The use of these would greatly improve the assessment of risk and greatly reduce unnecessary expenditure on antidotes.

Shorea robusta (Sal), an important traditional Indian medicinal plant used in various ailments and rituals and the indigenous use of the resin of this plant as a medicament for treatment of various inflammatory conditions is well documented in literature. In the present study, ethanolic extract of S. robusta resin (SRE) was evaluated for its analgesic activity by making use of different central and peripheral pain models. ⋯ The results of the present study demonstrate marked antinociceptive effects of SRE.
