ABSTRACT
The methanol stem bark extract of Neocarya macrophylla was screened for its analgesic activity using acetic acid-induced writhing in mice and formalin-induced pain in rats. The results of the study showed that the extract (60mg/kg, i.p.) decreased writhing response with 63.9% inhibition. The methanol extract also exhibited significant analgesic effect (P<0.05) in the formalin test which is in the same order of magnitude as that observed after administration of pentazocine (10mg/kg, i.p.) the standard drug. The intraperitoneal median lethal dose (LD50) of the methanol extract of N. macrophylla was found to be 283mg/kg in mice suggesting the plant is fairly toxic. The results of the study have shown that the methanol extract of N. macrophylla possesses analgesic activity which rationalizes the traditional use of the plant in the management of pain.
ABSTRACT
Background: Chronic myeloid leukaemia (CML); with a median age of 40 years; is one of the commonest haematological malignancies in Nigeria. Cytoreductive agents; which were hitherto the mainstay of treatment; neither induce cytogenetic nor haematologic remission. Alpha-interferon (a-IFN); an endogenous glycoprotein with cytotoxic and natural killer cell enhancer effects has been found to induce haematologic and cytogenetic remission in patients with CML; but neuro- psychiatric complications of a -interferon (a-IFN) usage were not reported in Nigeria. Objective: To report a case of deliberate self-harm in University Lecturer as a side effect of a-IFN in the treatment of CML. Method: Clinical and laboratory follow up of a patient receiving a-IFN in the management of CML from the time of diagnosis of CML to the point of loss of contact. Result: Severe depression is a complication that may adversely influence the clinical outcome of a-IFN usage Conclusions/Recommendations: Although interferon related depression is uncommon; it is suggested that pre-therapy interferon assays and neuro-psychiatric assessment are carried out in prospective users of a-IFN
