Mutagenicity testing of agent orange components and related chemicals.

Components of the herbicide Agent Orange--2,4-dichlorophenoxyacetic acid (2,4,-D) and 2,4,5-trichlorophenoxyacetic acid (2,4,5-T) and their esters, and the contaminant 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD)--and related chemicals were tested for mutagenicity using Salmonella typhimurium strains TA98, TA100, TA1535, and TA1537. No mutagenic activity was observed for any of the chemicals tested.

Phthalate ester testing in the National Toxicology Program's environmental mutagenesis test development program.

A number of phthalate esters and related chemicals were tested for mutagenicity in Salmonella typhimurium. The chemicals were tested blind in three laboratories by a preincubation modification of the Ames Salmonella/mammalian microsome test using S-9 prepared from Aroclor-induced rats and Syrian hamsters. All chemicals tested were judged to be nonmutagenic.

An evaluation of serum protein profiles in the long-term surveillance of prostatic cancer.

Longitudinal and vertical studies on prostatic cancer have confirmed that many forms of oestrogen therapy have a profound effect on the levels of several acute phase reactant proteins (APRP). This action overrides any response of the APRPs to a rising tumour load. However, serum C-Reactive protein and albumin levels appear to be independent of oestrogen control and their respective rise and fall is associated with tumour progression even when the patient is saturated with oestrogens.

Acute phase reactant proteins in the clinical management of carcinoma of the bladder.

The levels of a number of acute phase reactant proteins have been measured in 250 patients with carcinoma of the bladder in all stages. Three of them, acid glycoprotein, antichymotrypsin, and C-reactive protein, frequently gave abnormal results in advanced disease. The levels of these 3 proteins in patients who were clinically tumour-free were not distinguishable from those from an age-matched control group. The levels in patients with T1 and T2 bladder tumours were sometimes elevated. In advanced disease, figures were commonly above the normal range.
