Ethnobotanical surveys of Cerrado native plants show that leaves of Celtis iguanaea (Jacq.) Sargent (Cannabaceae), popularly known in Brazil as "esporão de galo", are used in folk medicine for body pain, asthma, cramps, poor digestion, urinary infection, kidney dysfunctions, as well as a stimulant and diuretic. This work aimed at evaluating possible C. iguanaea aqueous leaf extract (CALE) cytot...

Effects of some selective serotonergic (5-HT) antagonists on methamphetamine-induced anorexia were investigated in male mice. The least possible dose of methamphetamine alone that caused significant anorectic activity was 11 micromolkg(-1), i.p. (2 mgkg(-1)). Various doses of some selective serotonergic receptor antagonists were administered half an hour before the above mentioned dose of metha...

Cognisant of the negative debate and public sentiment about the land application of treated sewage sludges ('biosolids'), it is important to characterise such wastes beyond current regulated parameters. Concerns may be warranted, as many priority metal pollutants may be present in biosolids. This study represents the first time that extensive use was made of a handheld X-ray fluorescence (XRF) ...

This study was undertaken to investigate the leaf part of the plant for analgesic and anti-inflammatory. The ethanol extract of Ficus iteophylla leaves (100, 200, and 400 mg kg(-1), i.p) was evaluated for analgesic and anti-inflammatory activities. The analgesic effect was studied using acetic acid-induced abdominal constriction and hot plate test in mice, while the anti-inflammatory effect was...

Skin and ocular inflammation can co-exist in several inflammatory conditions such as rheumatoid arthritis, sarcoidosis, Wegener’s granulomatosis and polyarteritis nodosa. We report a case of non-diabetic necrobiosis lipoidica in whom periods of skin inflammation were associated with exacerbations of ocular inflammation in the form of intermediate uveitis and retinal vasculitis over 20 years. In...

To the Editor-In their article on the pharmacodynamics of rapacuro nium, Wright et at.’ stated that after a I.5-mg/kg dose, the drug’s time course of action (at the adductor pollicis) is similar to what they observed in a previous study after 1.0 mgkg of succinylcholine.2 I think this statement is somewhat misleading. Although the onset profiles of both drugs do indeed seem equivalent, the same...

To investigate the possible long-term consequences of gestational exposure to cannabinoids on cognitive functions, pregnant rats were administered with the CB1 receptor agonist WIN 55,212-2 (WIN), at a dose (0.5 mgkg) that causes neither malformations nor overt signs of toxicity. Prenatal WIN exposure induced a disruption of memory retention in 40- and 80-day-old offspring subjected to a passiv...

A study was conducted in the alluvial soils located in Oko-anala in Delta State, Nigeria. These alluvial soils are primarily used for intensive vegetable production for commercial purposes. The total land area of about 3.34 Square kilometer was divided into three consociations and composite soil samples collected from pre-determined depths of 0-15 and 16-30cm. The samples were routinely prepare...
