    Abstract:
    CONTEXT: Costus afer Ker Gawl. (Costaceae) is an ethnomedical plant used as therapy against inflammatory disorders. OBJECTIVE: The objective of this study was to evaluate the hematological and lipid profile analysis of hexane fraction of C. afer leaves (CAHLF) in arthritic rats. MATERIALS AND METHODS: Male albino rats were randomly distributed into seven groups of six rats each. Rats were induced with arthritis using formaldehyde and Complete Freund's Adjuvant (CFA) for 7 and 21 d, respectively. The animals were administered orally with 50, 100, and 250 mg/kg CAHLF, 10 mg/kg diclofenac and prednisolone, 0.9% NaCl (control), and 0.9% NaCl (normal). At the end of treatment periods, blood samples were withdrawn and subjected to hematological and biochemical analysis using auto-analyzer and spectrophotometric methods. RESULTS: Hematological analysis revealed that in formaldehyde- and CFA-induced arthritic rat models, 250 mg/kg CAHLF-treated groups had significantly reduced (p < 0.05) hematocrit counts (HC) (30.98 ± 1.59% and 33.55 ± 1.10%), white blood cell counts (WBC) (5.50 ± 0.35 and 4.15 ± 0.82 × 10(9)/L), and platelet counts (PC) (401.50 ± 48.94 and 246.33 ± 5.54 × 10(9)/L) compared with control HC (46.90 ± 1.92 and 41.88 ± 2.19%), WBC (11.09 ± 0.26 and 7.37 ± 0.34 × 10(9)/L), and PC (783.67 ± 59.51 and 593.83 ± 36.3 × 10(9)/L). Furthermore, blood analysis showed that CAHLF-treated groups had reduced total cholesterol, low-density lipoprotein cholesterol, and triglycerides while they had an elevated high-density lipoprotein compared with the control group. DISCUSSION AND CONCLUSION: Findings from this study indicated that CAHLF could possess immunomodulatory and hypolipidemic properties in arthritic rats. CAHLF could be considered as a source of biopharmaceutical agents in anti-arthritis drug discovery process.
