[Thyroxine (T4) levels in workers exposed to lead].

Thirty men occupationally exposed to lead have been examined. The selection of subjects was based on increased lead poisoning indices as well as on the data proving there had been no thyroid disease incidence noted prior to the lead poisoning. Each of the subjects underwent determination of T4 concentration simultaneously with the measurement of three basic indicators of lead poisoning: ALA in urine and ZPP and Pb in blood.

Bioavailability of trithiozine (TR) in man and its relation to gastric secretion and gastrin plasma level.

Pharmacokinetics and gastric secretion suppressing properties of a new drug, trithiozine (TR), were studied in man. Its availability, if taken orally, is prompt and very good; its blood plasma level lasts for over 5 hr. In basal conditions volume of gastric juice is suppressed by TR as it is by propantheline bromide (PPB).
