ABSTRACT Plants continue to be a major source of medicines as they have been throughout human history. A 2008 report from the Botanic Gardens Conservation International (representing botanic gardens in 120 countries) revealed that 5 billion people still use medicinal plants to partly cater for their health care needs. According to the World Health Organization, medicinal plants would be the best source of a variety of drugs (Toroglu, 2011). The fact that plants synthesize a wide variety of ch...
ABSTRACT Asthma is currently a worldwide problem, with increasing prevalence in both ?r children and adults; a prevalence rate of 5 - 10% has been reported for Nigeria. The pathophysiological features of the disease are bronchoconstriction, airway hyperresponsiveness and chronic inflammation. Drugs used in the management include bronchodilators which are short-term relievers and anti-inflammatory drugs which are long-term controllers. Despite the availability of oral and inhaled medications, ...
The aqueous root extract of Dalbergia saxatilis (DS) was used to study the pharmacological and toxicity profile of the plant, to ascertain the various medicinal uses and lack of toxicity claims by Traditional Medicine Practitioners. The 24h (up 14 days) acute toxicity and 90-day (plus 14 day reversibility) synchronic toxicity studies were explored to evaluate the toxicity potentials, and as basis for dose selection in the pharmacological studies. DS (50-200 mg/kg) was used to study the centra...
ABSTRACT Febrile illnesses occur frequently among HIV positive patients and these are often treated presumptively as malaria in endemic areas. Parasite-based diagnosis of malaria will eliminate unnecessary treatment, reduce drug–drug interactions and the chances for the emergence of drug resistant Plasmodium. We evaluated finger prick blood samples from 387 people living with HIV (PLWHIV) and suspected of having malaria by expert microscopy and Paracheck-Pf TM – a histidine-rich protein-I...

Erythrocyte sodium, potassium and water content have been determined in 908 Nigfferians so as to: 1. establish normal va! 2. compare values ^ values in other blacks. 3. compare va itSe> in Nigerians with those of caucasians. Red cell s^Üfum, potassium and water were also deterrrrined in 7 caucasians who had been resident i N n igeria for...
ABSTRACT The effect of PGE^, P5P?a and PGI0 on tilu lion induced by different mechanisms was studied in the isolated rat mesenteric arteiy as described by McGregor (1965) Vasoconstriction was induced by mechanisms involving dii modes of calcium utilization viz: (i) Pharmaccnechanical pathway by low doses of the adrenergic neurotransm.itter, noradrenaline acting at - receptor; (ii) electromechanical pathway by 1.1 b potassium-and” (iip.) agents which facilitate Ca influx e.g. A23187. ! The p...
ABSTRACT Background: Postpartum depression (PPD) is a mood disorder that affects 10 - 20 % of women after child birth. It has been observed that gestational iron deficiency which affects mostly mothers and their infants causes a deficit in behavioural, cognitive and affective functions precipitating depressive symptoms in both mothers and their infants during the postpartum period. The present work examined the role of iron in depression during the postpartum period in animal models. Method: ...
ABSTRACT Background: Current conventional antidepressant drugs have delayed onset of action, significant adverse effects, are costly and about 30-40% of patients are non-responsive, underscoring the need for alternative therapies for depression. Presently, no known scientific evidence exists to support the efficacy of Trichilia monadelpha in depression treatment, though used in Ghana in managing psychosis, epilepsy and mood disorders. Aim: This study investigated the antidepressant effect of ...
ABSTRACT Background: Synedrella nodiflora is a common weed in Ghana that is boiled to treat epilepsy and threatened abortion. The ethanolic whole plant extract has been demonstrated to have antiinflammatory, antioxidant, hypoglycemic, anticonvulsant, sedative, antidepressant and antipsychotic effects in murine models. The study presents the anti-oxidant and antihyperglycaemic effects of the ethanolic extract of the whole plant extract of Synedrella nodiflora (SNE) on a diabetic rat model. Met...
ABSTRACT Background: A major constraint in the management of People Living with Human Immunodeficiency Virus, with highly active antiretroviral therapy is the high incidence of adverse drug reaction among patients. Nevirapine, a non-nucleoside reverse transcriptase inhibitor is among the first-line antiretroviral therapy used in Ghana for the management of Human immunodeficiency virus-1 patients. Despite its usefulness, hypersensitivity reaction is a common complication that accounts for p...
ABSTRACT Background: Capparis erythrocarpos is a medicinal plant that is used extensively in folklore medicine in Ghana to manage various inflammatory conditions. Previous pharmacological study showed that an ethanolic extract of the roots of Capparis erythrocarpos may have antiinflammatory activity. However, no attempt has been made to investigate the basis of the effect(s), if any, of the aqueous extract on the inflammatory processes or ascertain its safety. Aim: The aim of this study was ...
