RESUMO
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.
RESUMO
OBJECTIVE: To evaluate the methanol leaf extract of Diaphanathe bidens (D. bidens) (AFZEL. EX SW) SCHLTR for antihyperglycemic activity in order to confirm it antidiabetic potential. METHODS: D. bidens was extracted by cold maceration for 48 h and concentrated in vacuo to yield D. bidens extract (DBE). Hyperglycemia was induced by intraperitoneal administration of streptozotocin (75 mg/kg). Oral glucose tolerance test was done with 2 g/kg glucose load in normal rats. DBE (150, 300 and 600 mg/kg) was administered orally, while tolbutamide (100 mg/kg, p.o.) was used as the standard reference drug. Blood glucose levels determined using ACCUCHEK glucose auto-analyzer. The acute toxicity and phytochemical studies were also carried out. RESULTS: DBE (600 mg/kg) and tolbutamide (100 mg/kg) significantly (P<0.05, 0.005) reduced blood glucose levels of rats between 120 and 480 min post administration in normal rats. In the streptozotocin- induced hyperglycemic rats, DBE (150, 300, 600 mg/kg) caused significant (P<0.001) dose- and time- dependent reduction in the blood glucose levels by 1.7%, 22.8% and 43.4%, respectively at 480 min compared to the negative control group. DBE (600 mg/kg) reduced the blood glucose level of rats by 1.2% in the oral glucose tolerance test when compared with the normal saline treated group. The acute toxicity test showed that DBE was safe at the doses used and the phytochemical screening revealed the presence of saponins, steroids, tannins and terpernoids. CONCLUSIONS: D. bidens extract possess antihyperglycemic activity which may be mediated through pancreatic and extra-pancreatic pathways, thereby justifying it folkloric use.
