Shifa Hospital,DHA, Phase 2, Karachi, Pakistan.AbstractPurpose: To evaluate the effect of Cedrus deodara (Pinaceae) root oil, used traditionally for thetreatment of various ailments, on the histopathology of the liver and kidney of Wistar albino rats.Methods: The oil was extracted from the plant root by dry destructive distillation method andadministered orally at doses of 0.5 ml and 2.5 ml per rat. Each animal group was comprised of 30 rats.Treated and untreated group of rats were sacrificed and organs (liver and kidney) were taken out fortissue processing and staining with haematoxylin and eosin according to the method of Bancroft andStevens. Microscopic examination was then carried out to observe any pathological changes in theanimals.Results: The root oil produced atrophic changes and haemolysis in the glomerular region as well asshrinkage and shedding of glomerular epithelium in the kidney tissues. Marked dilation of the centralvein and congested blood vessels in the rat liver at both doses tested was also seen.Conclusion: The root oil of C. deodara (Pinaceae), at the doses administered, produced some adverseeffects on the tissues tested but these effects were not lethal. Some toxic changes in the tissues of liverand kidney were also found.Keywords: Histopathology, Cedrus deodara root oil, Liver, Kidney, Albino rats.Received: 15 October 2009 Revised accepted: 25 February 2010*Corresponding author: E-mail:; Tel: +9221-4410434; Fax: +9221-4410439 Trop J Pharm Res, April 2010; 9 (2): 127
  2. 2. Parveen et alINTRODUCTION accumulation of polycyclic aromatic hydrocarbons (PAHs) in two kinds of pineCedrus deodara (Deodar - Pinaceae) is found (Cedrus deodara and Pinus thunbergii)in the hilly areas of North Western Frontier needles [10].Province (N.W.F.P.) of Pakistan and also inthe Western Himalaya and the Mediterranean Considerable work has been done on theregion. It is a tall evergreen tree with chemistry of stem bark in Pakistan and Indiaspreading horizontal branches having circular to analyse stem bark extract or oil [11-14] butleaves. In the Indus-Unic system (previously to the best of our knowledge, no scientificUnani or Greek system), the plant’s extracts, studies have been reported in the literatureoils, etc, have been used in Eastern medicine on the analysis of Cedrus deodara root oilfor a long time in the treatment of patients for and its pathological effects on animal tissues.various ailments. For example, the wood Therefore, the objective of this study was toextract is carminative, diaphoretic and investigate the effect of Cedrus deodara rootantipyretic, and has also been used to treat oil on the liver and kidney tissues of albinoflatulence, pulmonary and urinary disorders, rats (Wistar Strain) at low and high doserheumatism, piles and kidney stones. In levels.addition, the bark extract is astringent andalso useful for treating fever, diarrheoa and EXPERIMENTALdysentery [1].
