Endocrine disrupting chemicals (EDC) are released into environment from different sources. They are mainly used in packaging industries, pesticides and food constituents. Clinical evidence, experimental models, and epidemiological studies suggest that EDC have major risks for human by targeting different organs and systems in the body. Multiple mechanisms(More)
OBJECTIVE Benzene, as a volatile organic compound, is known as one of the main air pollutants in the environment. The aim of this review is to summarize all available evidences on non-cancerous health effects of benzene providing an overview of possible association of exposure to benzene with human chronic diseases, specially, in those regions of the world(More)
Xylene is a cyclic hydrocarbon, and an environmental pollutant. It is also used in dyes, paints, polishes, medical technology and different industries as a solvent. Xylene easily vaporizes and divides by sunlight into other harmless chemicals. The aim of the present review is to collect the evidence of the xylene toxicity, related to non-cancerous health(More)
Benzene (C6H6) is an organic compound used in petrochemicals and numerous other industries. It is abundantly released to our environment as a chemical pollutant causing widespread human exposure. This study mainly focused on benzene induced toxicity on rat pancreatic islets with respect to oxidative damage, insulin secretion and glucokinase (GK) activity.(More)
This review is undertaken to address the possible role of arsenic and pesticides in the prevalence of diabetes in Pakistan and to highlight a resourceful targeted research in this area. A bibliographic search of scientific databases was conducted with key words of "epidemics of diabetes in Pakistan", "diabetes in Asia", "diabetes mellitus and environmental(More)
The intention of this article is to call the reader's attention to the underestimated, yet very serious issue of chronic exposure to elemental mercury from dental amalgams. Dental amalgam is an alloy used for tooth fillings that contains about 50 % of elemental mercury and has been used in hundreds of millions of patients for the last 160 years throughout(More)
INTRODUCTION Pesticides are among the most important chemicals used in agriculture sector. However, their extensive use has polluted the environment and increased human vulnerability to various chronic diseases. Pesticide exposure causes genetic and epigenetic modifications, endocrine disruption, mitochondrial dysfunction and oxidative stress. Areas(More)
Lead (Pb) is a toxic heavy metal known to be associated with pathology of various human chronic diseases. This study has focused on the effect of lead on glucose homeostasis with regard to metabolic function of pancreas and liver. Islets of Langerhans were isolated from the pancreas of rats and exposed to lead for 24h, then insulin release along with(More)
The immune system is an integrated organization, comprising of specific organs, cells and molecules playing a crucial role in the maintenance of health. The purpose of this paper is to give a mechanistic overview of toxic effects of various chemicals and pharmacological agents, and their interaction with the various components of the immune system that(More)
Benzene (C6H6) is one of the most commonly used industrial chemicals causing environmental pollution. This study aimed to examine the effect of benzene and its metabolite hydroquinone on glucose regulating organs, liver and pancreas, and to reveal the involved toxic mechanisms, in rats. In the in vivo part, benzene was dissolved in corn oil and administered(More)
