Anti-anaemic effect of ethanol leaf extract of Cnidosculus aconitifolius on cyclophosphomide-induced anaemia in rats.

BACKGROUND: The folkloric claim that Cnidoscolus aconitifolius (Chaya) could ameliorate anaemia requires scientific revalidation in anaemic models. OBJECTIVE: The aim of this study is to investigate the anti-anaemic effect of Cnidoscolus aconitifolius on cyclophosphamide-induced anaemia in rats. METHODS: The leaves of Cnidoscolus aconitifolius were collected, dried and extracted with ethanol. Twenty five Wistar Albino rats weighing 120-180 kg were used. Anaemia was induced in groups 2, 3, 4 and 5 with a single injection of cyclophosphamide, while group 1 served as a negative control without anemia and was treated with 0.5 mL of normal saline, Group 2 rats were treated with 100 mg/kg body weight of Cnidoscolus aconitifolius. Group 3 rats were treated with 500 mg/kg body weight of Cnidoscolus aconitifolius. Group 4 served as the positive control rats and was treated with 0.5 mL of normal saline. Group 5 which served as the standard control rats and were treated with 5 mg/kg body weight of standard drug Chemiron. The treated lasted for two weeks during which blood samples were collected from each rat for haematological analysis. RESULTS: The result shows that hematological parameters were elevated in groups 2, 3 and 5 rats treated with 100 mg/kg and 500 mg/kg body weight of ethanol extract of Cnidoscolus aconitifolius and chemiron respectively. CONCLUSIONS: Ethanol leaf extract of Cnidoscolus aconitifolius at a graded dose of 500 mg/kg body weight had higher ameliorative effect on the haematological parameters of cyclophosphamide-induced anemia in rats.

Hematological prediction study of peritonitis following laparotomy in goats.

Surgical trauma to the abdominal wall and peritoneum during celiotomy is expected to cause postoperative inflammation. However, complications after abdominal surgery are hardly detected in the early stage. Hematological analysis of blood has been considered beneficial in disease diagnosis and prognosis. This study aimed to evaluate the hematological parameters predicting peritonitis in goats and to determine the post-surgery day that hematology is significant. Six apparently healthy West African Dwarf goats were included in this study. After 2 weeks of acclimatization, blood samples were obtained daily for 3 days for hematological analyses, which served as the baseline data. The right flanks of the animals were aseptically prepared routinely for exploratory laparotomy. Restraint and anesthesia were achieved using xylazine and lignocaine using an inverted "L" block technique. Laparotomy was performed, and the incision was left for 20 min and then closed routinely. Blood samples were collected for hemogram 24 hr postoperatively and daily for 7 days. Based on the post-surgery hematology results, relative neutrophil (P=0.015) and lymphocyte (P=0.006) counts significantly increased and decreased on day 5 respectively. Significant differences were also observed for red blood cell count, hemoglobin concentration, and packed cell volume on days 5, 6, and 7 respectively. It could therefore be concluded that the diagnostic result for hematology post-laparotomy can be obtained on the fifth and sixth day.
