In order to elucidate the importance of food-borne chemical contamination in fish, cytological and ultrastructural alterations in hepatocytes and enterocytes of common carp Cyprinus carpio L. exposed for 5 wk to 0.5 microgram endosulfan (6,7,8,9,10,10-hexachloro-1,5,5a,6,9a-hexahydro-6,9-methano-2,4,3-benzo- dioxyanthiepin-3-oxide) kg-1 food dry weight, equivalent to an ultra-low dosis of 15 ng...

Individuals, typically, are exposed to mixtures of environmental xenobiotics affecting multiple organs and acting through different xenosensors and pathways in species and cell-type specific manners. 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) and α-endosulfan are Persistent Organic Pollutants (POPs) and endocrine disruptors which act through different xenosensors and accumulate in the liver. Ou...

Humans are usually exposed to several pesticides simultaneously; consequently, combined actions between pesticides themselves or between pesticides and other chemicals need to be addressed in the risk assessment. Many pesticides are efficient activators of pregnane X receptor (PXR) and/or constitutive androstane receptor (CAR), two major nuclear receptors that are also activated by other substr...

In an agricultural country like India, pesticides are a major aquatic chemical pollutant. The broad class of and biological agents that damage or kill pests. There mainly three groups synthetic organic pesticides-organochlorines, organophosphates carbamates. Fishes the vulnerable biotic components as they sequester effects to higher organisms including man through food chain. this paper attempt...

Altered immune responses have been observed following occupational, inadvertent, or therapeutic exposure to xenobiotics. Many pesticides are known to cause immunotoxicity. Exposure to mixtures of pesticides, either concurrently or sequentially, may result in potentiating this effect partly because one can effect the metabolism of the other. The objective of this study was to determine the effec...
