A review of the literature reveals two primary issues: (1) a weak, but not causal, association of hygienic use of cosmetic talc and ovarian cancer; (2) lung changes in animals exposed to talc aerosol concentrations that resulted in lung overload. The

When neutron-activated talc was suspended in bovine serum, 0·5% of the 60 Co and 3·1% of the 46 Sc occurring in the sample was found in the supernatant of the centrifuged and filtered suspension. A maximum of about 0·5% of each radionuclide can be

Four-month-old female albino rats received a single 15 to 20 minute “nose-only” exposure to 239 PuO 2 dust (CMD 0.3μm). The animals were then randomly divided into experimental and control groups of 10, 12 and 18 rats each for three exploratory

Summary To determine talc absorption in the gastro-intestinal tract of hamsters, talc was neutron-activated and suspended in physiological saline and 1-ml aliquots of this suspension were administered by gastric intubation to six 10-wk-old Syrian gol

Groups of 50 male and 50 female Syrian golden hamsters were exposed to talc aerosol for 3, 30 or 150min/day, 5 days/wk for 30 days, or for 30 or 150min/day either until they died naturally or for a maximum of 300 days. The mean concentration of the

To determine pulmonary deposition, translocation and clearance of inhaled talc, 10-wk-old hamsters received a single 2-hr nose-only exposure to neutron-activated talc. Over a period of 4 months, the hamsters were killed in groups of four. Lungs, live

To investigate whether particles deposited in the vagina translocate to the oviducts, 0.3 ml of a 4% bone black suspension was deposited in the posterior vaginal fornix of each of five cynomolgus monkeys (Macaca fascicularis) during their mid-menstru

The objective of this study was to investigate whether multiple vaginal depositions of neutron-activated talc in the cynomolgus monkey result in the translocation of this material to the uterus and beyond. Within a 45-day period, six monkeys received
