In clinical practice, Total Parenteral Nutrition (TPN) is standard of care for patients of gastrointestinal tract disorders. TPN therapy is associated with a number of adverse effects like hepatobiliary dysfunction, dyslipidemia, and oxidative stress. Different vegetable oils are used by every individual daily in routine life.


This study assessed the magnitude of TPN-associated adverse effects in animals fed on different vegetable oils.


Healthy adult rabbits of local strain were divided into 5 groups (n= 8). The study was divided into 2 phases. Phase I: oil feeding; the first set of rabbits served as control and fed on a normal rabbit diet. Four sets of rabbits were treated for 16 weeks with 1 ml/kg/day of single time heated olive (STH-OO), canola (STH-CO), sunflower oils (STH-SO) or a mixture of these oils (STH-MVO). In phase II: TPN was given to each group, including the control group, for 2 weeks. Before and after TPN therapy, body and liver weights were measured. Plasma lipid profile [triglycerides, total cholesterol, high-density lipoproteins, low-density lipoproteins, very-low-density lipoproteins], liver function marker [total-protein, albumin, total and direct bilirubin, serum glutamic pyruvic transaminase, serum glutamic-oxaloacetic transaminase, gamma-glutamyl transferase, and alkaline phosphatase], oxidative stress and tissue damage parameters [malondialdehyde, C-reactive protein, lactate dehydrogenase, and creatine phosphokinase] of all the groups weremeasured at the end of TPN therapy.


Significantly (p <0.05) elevated hepatic enzymes, oxidative stress and tissue damage markers along with dyslipidemia were observed in STH-MVO and STH-SO fed groups, in comparison to control. In STH-OO and STH-CO groups, all these parameters were insignificantly different than control after 2 weeks of TPN therapy. The higher plasma levels of, High-Density Lipoproteins (HDL), total protein and albumin and reduced Malondialdehyde (MDA) levels, were observed in STH-OO and STH-CO groups than the control.


This study recommends that high monounsaturated fatty acids containing oils like olive and canola oils, are found to have strong resistance against the hepatic injury and lipid peroxidation. The study also recommends taking the history of oil use by an individual before the initiation of therapeutic agents with known side effects of hepatic toxicity and dyslipidemia.

Keywords: Total Parenteral Nutrition (TPN), Hepatobiliary disorders, Poly Unsaturated Fatty Acids (PUFA), Monounsaturated Fatty Acids (MUFA), High-Density Lipoproteins (HDL), Malondialdehyde (MDA) levels.

"Open access will revolutionize 21st century knowledge work and accelerate the diffusion of ideas and evidence that support just in time learning and the evolution of thinking in a number of disciplines."

Daniel Pesut
(Indiana University School of Nursing, USA)

"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
