Toxicity

Paraquat dichloride, a herbicide used for weed and grass control, is extremely toxic to humans and animals. The data indicate that betamethasone exacerbates the toxic effects of paraquat.

Dosage Studied

Paraquat is a pro-oxidant molecule aiming at increasing oxidative stress. The rate of adsorption has been investigated under the controlled process parameters. Intraperitoneal administration of paraquat to mice produced a linear dose-response increase (20 to 50 mg/kg of body weight) in serum angiotensi.

" The pathology in the lung can be divided into two distinct phases: (1) a destruction phase lasting a few days with damage to the type I and type II alveolar epithelial cells, oedema and haemorrhage (most of the rats which die after dosing with paraquat do so during this phase); (2) a reparative phase with regeneration of the epithelium and, in areas of severe damage, a characteristic proliferation of fibroblasts."( The pathology and biochemistry of paraquat.
