ABSTRACT
Abstract This study aims to investigate the effects of orally administered graded doses of hydro-methanol stem extract from Anacardium occidentale (MSEAO) on the haematology and serum biochemistry of chickens. Forty, 8-weeks old cockerel chickens were randomly assigned into four groups (groups 1, 2, 3 and 4) of ten birds each. Groups 1, 2 and 3 received 3000, 1500 and 500 mg/kg body weight of MSEAO, respectively, while chickens in control group (group 4) were given drinking water placebo. Blood samples were collected from all chickens on day 0- and 48-hours post-treatment. Haematology and serum biochemistry were evaluated following standard procedures. The results showed that most of the haematological parameters in the treated groups did not differ significantly as compared to the control group. The serum biochemistry results showed that the serum alanine aminotransferase (ALT) activity ingroups 1 and 2 were significantly (P < 0.05) lower than that ingroups 3 and 4. Serum uric acid levels ingroups 1 and 2 chickens were significantly (P < 0.05) lower than that in the control group, while the creatinine levels of chickens in the treated groups were significantly (P < 0.05) lower than that of chickens in the control group. It was concluded that MSEAO, as used in the study, led to significant changes in heterophil counts, serum ALT and ALP activities, uric acid, creatinine, and calcium levels.
Resumen El objetivo de este estudio es investigar los efectos de dosis graduales de extracto de hidro-metanol del tallo de Anacardium occidentale (MSEAO) administradas por vía oral sobre la hematología y bioquímica del suero de polluelos. Cuarenta pollos de 8 semanas de edad fueron asignados al azar en cuatro grupos (1, 2, 3 y 4) de diez pollos cada grupo. Los grupos 1, 2 y 3 recibieron 3000, 1500 y 500 mg/kg de peso corporal de MSEAO, respectivamente, mientras que a los pollos del grupo de control [grupo 4] se les dio agua de beber como placebo. Se tomaron muestras de sangre de todos los pollos a las 0 y 48 horas después del tratamiento. Se evaluó la hematología y la bioquímica del suero siguiendo procedimientos estándares. Los resultados mostraron que la mayoría de parámetros hematológicos en los grupos tratados no difirieron significativamente con respecto al grupo de control. Los resultados de la bioquímica del suero mostraron que la actividad de la alanina aminotransferasa en el suero (ALT) en los grupos 1 y 2 fue significativamente inferior (P < 0.05) a la de los grupos 3 y 4. Los niveles de ácido úrico en el suero en los pollos de los grupos 1 y 2 fueron significativamente inferiores (P < 0.05) a los del grupo de control, mientras que los niveles de creatinina de los pollos en los grupos de tratamiento fueron significativamente inferiores (P< 0.05) a los de los pollos del grupo de control. Se concluyó que el MSEAO, como se usó en este estudio, produjo cambios significativos en los conteos de heterófilos, en las actividades de ALT y ALP del suero y en los niveles de ácido úrico, creatinina y calcio.
ABSTRACT
@#Introduction: Root canal treatment often fails because of bacteria that grow back after obturation, such as Enterococcus faecalis (E. faecalis). The previous study has found the percentage of root canal treatment failure as much as 32-70%. It was because the facultative anaerobic bacteria are able to penetrate into the dentinal tubules and found to be resistant. Ambonese banana stem is one of the herbal plants in Indonesia that has been widely used, including the sap on the stem. Active substances in the sap of Ambonese banana stems such as flavonoids, saponins, and tannins have antimicrobial efficacy. The purpose of this study is to prove the antibacterial activity of Ambonese banana stems extract on E. faecalis and analyzing bacterial viability through a fluorescent microscope. Methods: The sample of this study was E. faecalis (ATCC 29212) which bred on BHIB media, then serially carried out dilution with Ambonese banana stem extract with a composition of 100%, 50%, 25%, 12.5%, 6.25%, 3.125 %, 1,563%. and 0.781%. Cultured in the Agar Mueller-Hinton medium and then calculate the number of bacterial colonies. This examination was continued using a fluorescent microscope for determining the viability of bacteria. Results: We obtained MIC at a concentration of 1.563% and MBC at a concentration of 3.125%. The ability of Ambonese banana stem extracts to kill E. faecalis in MIC was 92.22%, while in MBC it was 100%. Conclusion: Ambonese banana stem extract effectively inhibited the growth of E. faecalis bacteria.
ABSTRACT
The present work was attempted to study the Antibacterial activity and phytochemical analysis of Mangrove plant Avicennia alba. Leaf and stem extracts of A. alba were prepared in Hexane, Benzene, Chloroform, Ethyl acetate, Acetone and Methanol solvents. The resulted extracts of the plant were screened for antibacterial activity against Micrococcus luteus MTCC 106, Arthrobacter protophormiae MTCC 2682, Rhodococcus rhodochrous MTCC 265, Alcaligens faecalis MTCC 126, Proteus- mirabilis MTCC 425, Enterobacter aerogenes MTCC 10208, Proteus vulgaris MTCC 426, Bacillus megaterium MTCC 428, Enterococcus faecalis MTCC 439, Streptococcus mutans- MTCC 497, Salmonella enterica MTCC 3858, Staphylococcus aureus MTCC 737, Pseudomonas aeruginosa MTCC 1688 and Bacillus subtilis MTCC 441. The extracts were also screened for phytochemicals like Carbohydrates, Tannins, Steroids, Terpenoids, Saponins, Flavanoids, Alkaloids and Soluble starch. Of the six solvent extracts of A. alba, ethyl acetate and acetone extracts of leaf and stem, with few exceptions, showed relatively high antibacterial activity. Benzene and chloroform extracts of A. alba showed a larger zone of inhibition against Salmonella enterica than other bacteria. A. alba leaf and stem extracts of different solvents showed good antibacterial activity against Gram negative bacteria than the Gram positive bacteria tested. Most of the solvent extracts of leaf and stem are effective on many bacteria tested than the positive control. The acetone and methanol extracts of leaf and stem showed maximum positive results towards the phytochemical constituents.
