title: The effect of endotoxin and radio-detoxified endotoxin on the serum T4 level of rats and response of their thyroid gland to exogenous TSH.
abstract: We have demonstrated that, while the shock-inducing dose of parent (toxic) endotoxin significantly decreases the serum T4 level of rats and inhibits the T4 response given to exogenous thyroid stimulating hormone (TSH), the radio-detoxified (60Co-gamma, 150 kGy) endotoxin preparation does not inhibit the response to exogenous TSH and decreases serum T4 level to a lesser extent than untreated endotoxin.
