Variation of glutathione levels in Finnsheep.

Blood glutathione was measured in Finnsheep. Inheritance data show that the two types of GSH concentrations were under independent genetic control. GSH levels were found to be associated with potassium levels and reproduction in Finnsheep.

Urinary polyamine excretion during the menstrual cycle.

Urinary polyamines were measured by a fluorometric thin-layer chromatographic technique in samples collected daily throughout a single menstrual cycle by each of 13 healthy women. Polyamine excretion fluctuated considerably, but excretion of putrescine, spermidine, and spermine combined was consistently greatest during menstruation, sometimes extending into the early follicular phase of the cycle. Enhanced excretion of polyamines was also noticed in many individuals at the approximate time of ovulation.
