ABSTRACT
Introduction:Cutaneous adverse drug reactions are one of the most common adverse drug reactions. Publicationson clinical correlation between cutaneous presentations and causative agents are limited among thelocal population. This study aims to determine the clinical presentations of cutaneous adverse drugreactions and the causative drugs in the local population.Methods:A retrospective, cross sectional study was conducted from the pharmacy cutaneous adverse drugreaction database from January 2014 to December 2016 in Tawau, Keningau & Queen Elizabeth (KotaKinabalu) Hospitals.Results:A total of 859 cases of cutaneous adverse drug reactions were identified. Out of these, 53.3% (n=458)were females and 46.7% (n=401) were males. The mean age was 36 years old. Majority of patients were20-29 years old (16.6%) followed by 50-59 years old (15.1%). Most of the cases were reported amongthe Chinese community (16.4%), followed by the Malay (15.9%), Dusun (14.7%) and Bajau (14.0%)populations. The most common cutaneous manifestations were urticaria and or angioedema (49%, n=421) and maculopapular rash (39.6%, n=340). Severe cutaneous adverse reactions (SCAR) constituted2.8% in total. The major causative agent was antibiotic which accounted for 55.1% (n=473), followedby nonsteroidal anti-inflammatory drugs (NSAIDs), 28.1% (n=241) and analgesics, 10.8% (n=93).Conclusion:The types of cutaneous manifestations and causative drugs in Sabah are similar to those reported inother states of the country and abroad. This study provides evidence of local cutaneous adverse drugreaction characteristics in different ethnic group.
ABSTRACT
To assess the antibacterial activities of Coccinia grandis leaf extract on selective bacterial strains under in-vitro conditions. The antibacterial activity was tested against five bacterial strains by agar well diffusion method. The crude extract showed a broad spectrum of antibacterial activity by inhibiting both the gram positive and gram negative groups. The antibacterial activity of C.grandis leaf extract using solvents such as acetone, ethanol, methanol, aqueous and hexane was evaluated against five bacterial sp. Ethanol leaf extract of C.grandis showed high antibacterial activity against S.aureus, B.cereus, E.coli, K.pneumoniae and S.pyogens. Minimal inhibitory concentration of the leaf extract against each test organism was also studied by observing their growth on Mueller Hinton Agar containing the extract at various incremental levels, equivalent to 31.25μg/ml to 1000μg/ml of the extract. The highest activity was observed in ethanol extracts against S.aureus, E.coli, and K.pneumoniae with an inhibitory concentration below 31.5μg/ml. The significance of the study was conducted to investigate the invitro antibacterial activity of folklore medicinal plant and to evaluate scientific base of their applications.
ABSTRACT
To investigate the protective effect of the leaf extract of Andrographis paniculata (Ap) against ethanol induced liver toxicity in male albino rats. The liver toxicity was induced by the administration of ethanol to the animals at the optimum dosage of 7.9g/kg body wt., orally for 45 days. After induction of liver toxicity the aqueous plant extract of A.p was administered to the animal 250 mg/kg body wt., for 45 days. The liver toxicity and protective effect of the plant extract was assessed by the estimation of liver marker enzymes, antioxidant enzymes and liver histopathological studies. The ethanol induced animals the liver marker enzymes like ALT, AST, ALP and Bilirubin were significantly elevated (P<0.001) when compared to the normal animals. After administration of aqueous extract of A.p the elevated levels of marker enzymes were significantly decreased (P<0.001). The antioxidant enzymes were decreased significantly in ethanol induced animals after administration of plant extract the decreased levels were increased significantly (P<0.001). The aqueous leaf extract of A.paniculata could protect the liver against ethanol induced liver toxicity by possibly reducing the rate of lipid peroxidation and increasing the antioxidant defense mechanism in rats.
