Pituitary function tests in Sheehan's syndome.

Fourteen patients with a typical history of Sheehan's syndrome underwent pituitary function tests with simultaneous injections of 100 micrograms LH-RH, 200 micrograms TRH and 0.05--0.1 units of soluble insulin per kg body weight. Serum prolactin levels remained unchanged in all of eleven subjects given TRH. GH levels did not rise after hypoglycaemia in five subjects. In contrast serum LH and FSH rose significantly in twelve out of fourteen subjects given LHRH and serum TSH rose significantly in five out of seven subjects given TRH. It is concluded that pituitary function is relatively preserved for LH and FSH but not for prolactin and GH in Sheehan's syndrome. It is further suggested that absence of a rise in prolactin following TRH stimulation may provide the most sensitive test of pituitary hypofunction in postpartum haemorrhage.

The effects of prolonged consumption of wholemeal bread upon metabolism of calcium, magnesium, zinc and phosphorus of two young American adults.

The ability to adapt to a large daily intake of unleavened bread made from wheaten wholemeals of high extraction rate was examined in two young Americans who had not previously consumed fiber, phytate-, and phosphate-rich bread of this type. Adaptation was evaluated by comparing balances of zinc, calcium, magnesium, and phosphorus for a 12 day period after ten days of bread consumption with those during a similar period after 50 days and also by observing changes in blood composition during this period of bread consumption. Significantly negative balances of zinc, magnesium and phosphorus were observed in the initial period. However, all had become positive or nearly so after 50 days. By contrast, calcium balances which were also negative during the initial period remained negative at the end of the study. Plasma calcium and zinc concentrations had declined to low normal or subnormal values at this time. The failure to overcome the disturbing effects of consumption of wholemeal bread upon calcium metabolism occurred despite daily exposure to sunshine for many hours under conditions favorable for Vitamin D biosynthesis.
