Overdose of paracetamol (PCM) will cause liver injury through free radical activity. Morinda citrifolia extract was found to reduce the oxidative stress in many pathological conditions. Hence, the aim of this study was to evaluate the therapeutic potential of polysaccharide rich fraction (PS) of M.citrifolia as hepatoprotective agent based on the assessment of liver function test, oxidative stress and liver morphology changes. Male adult Sprague-Dawley rats were divided randomly into six groups of control, PS. M.citrifolia 400mg/kg (PS400), PCM, PS.M.citrifolia (200mg/kg)+PCM (PS200+PCM), PS.M.citrifolia (400mg/kg)+PCM (PS400+PCM) and silymarin+PCM. Supplementation was given for seven consecutive days of forced oral and one hour after the last supplementation, induction of liver injury was done by given single dose of PCM (2g/kg) orally. Following 48 hours, all rats were sacrificed, plasma and liver sample were taken immediately. Research findings showed levels of alanin aminotransaminase (ALT), aspartate aminotransferase (AST), and total bilirubin in plasma was significantly (p<0.05) lower in PS200+PCM and PS400+PCM compared with PCM group. Meanwhile, total protein and γ-glutamyl transferase (GGT) of plasma in PS200+PCM and PS400+PCM group showed no significant difference (p<0.05) compared with PCM group. Pretreatment of PS.M.citrifolia also significantly (p<0.05) increased glutathione (GSH) level, malondialdehyde (MDA) and protein carbonyl concentration and activity of catalase (CAT) and superoxide dismutase (SOD) in hepatic tissue compared with PCM group. Histological observation showed both PS.M.citrifolia treated groups prevent disruption of normal liver cells architecture induced by PCM.These data suggest that polysaccharide rich fraction M.citrifolia has the therapeutic potential as hepatoprotective agent against PCM induce liver injury.

"It is important that students and researchers from all over the world can have easy access to relevant, high-standard and timely scientific information. This is exactly what Open Access Journals provide and this is the reason why I support this endeavor."

Jacques Descotes
(Centre Antipoison-Centre de Pharmacovigilance, France)

"Publishing research articles is the key for future scientific progress. Open Access publishing is therefore of utmost importance for wider dissemination of information, and will help serving the best interest of the scientific community."

Patrice Talaga
(UCB S.A., Belgium)

"Open access journals are a novel concept in the medical literature. They offer accessible information to a wide variety of individuals, including physicians, medical students, clinical investigators, and the general public. They are an outstanding source of medical and scientific information."

Jeffrey M. Weinberg
(St. Luke's-Roosevelt Hospital Center, USA)

"Open access journals are extremely useful for graduate students, investigators and all other interested persons to read important scientific articles and subscribe scientific journals. Indeed, the research articles span a wide range of area and of high quality. This is specially a must for researchers belonging to institutions with limited library facility and funding to subscribe scientific journals."

Debomoy K. Lahiri
(Indiana University School of Medicine, USA)

"Open access journals represent a major break-through in publishing. They provide easy access to the latest research on a wide variety of issues. Relevant and timely articles are made available in a fraction of the time taken by more conventional publishers. Articles are of uniformly high quality and written by the world's leading authorities."

Robert Looney
(Naval Postgraduate School, USA)

"Open access journals have transformed the way scientific data is published and disseminated: particularly, whilst ensuring a high quality standard and transparency in the editorial process, they have increased the access to the scientific literature by those researchers that have limited library support or that are working on small budgets."

Richard Reithinger
(Westat, USA)

"Not only do open access journals greatly improve the access to high quality information for scientists in the developing world, it also provides extra exposure for our papers."

J. Ferwerda
(University of Oxford, UK)

"Open Access 'Chemistry' Journals allow the dissemination of knowledge at your finger tips without paying for the scientific content."

Sean L. Kitson
(Almac Sciences, Northern Ireland)

"In principle, all scientific journals should have open access, as should be science itself. Open access journals are very helpful for students, researchers and the general public including people from institutions which do not have library or cannot afford to subscribe scientific journals. The articles are high standard and cover a wide area."

Hubert Wolterbeek
(Delft University of Technology, The Netherlands)

"The widest possible diffusion of information is critical for the advancement of science. In this perspective, open access journals are instrumental in fostering researches and achievements."

Alessandro Laviano
(Sapienza - University of Rome, Italy)

"Open access journals are very useful for all scientists as they can have quick information in the different fields of science."

Philippe Hernigou
(Paris University, France)

"There are many scientists who can not afford the rather expensive subscriptions to scientific journals. Open access journals offer a good alternative for free access to good quality scientific information."

Fidel Toldrá
(Instituto de Agroquimica y Tecnologia de Alimentos, Spain)

"Open access journals have become a fundamental tool for students, researchers, patients and the general public. Many people from institutions which do not have library or cannot afford to subscribe scientific journals benefit of them on a daily basis. The articles are among the best and cover most scientific areas."

M. Bendandi
(University Clinic of Navarre, Spain)

"These journals provide researchers with a platform for rapid, open access scientific communication. The articles are of high quality and broad scope."

Peter Chiba
(University of Vienna, Austria)

"Open access journals are probably one of the most important contributions to promote and diffuse science worldwide."

Jaime Sampaio
(University of Trás-os-Montes e Alto Douro, Portugal)

"Open access journals make up a new and rather revolutionary way to scientific publication. This option opens several quite interesting possibilities to disseminate openly and freely new knowledge and even to facilitate interpersonal communication among scientists."

Eduardo A. Castro
(INIFTA, Argentina)

"Open access journals are freely available online throughout the world, for you to read, download, copy, distribute, and use. The articles published in the open access journals are high quality and cover a wide range of fields."

Kenji Hashimoto
(Chiba University, Japan)

"Open Access journals offer an innovative and efficient way of publication for academics and professionals in a wide range of disciplines. The papers published are of high quality after rigorous peer review and they are Indexed in: major international databases. I read Open Access journals to keep abreast of the recent development in my field of study."

Daniel Shek
