In vitro effects of thyroxine on the mechanical properties of erythrocytes.

In vitro effects of thyroxine on erythrocyte deformability and mechanical fragility were observed. Deformability of erythrocytes was improved in a dose dependent manner by thyroxine. Mechanical hemolysis was found to be lower if thyroxine was included in erythrocyte suspensions at concentrations close to the physiological levels (10(-9)M). These changes might be related to the alterations of intracellular calcium concentration, as in the erythrocyte suspensions containing 10(-9)M thyroxine, intracellular calcium concentration was found to be 30 times lower than the control suspensions which did not contain thyroxine. Thyroxine also reduced the mechanical hemolysis ratio in calcium loaded cells. These observations suggest that thyroxine might play some role in the regulation of the mechanical properties of erythrocytes which might be mediated via the effects on calcium metabolism.

A different approach to sleep problems of infancy: swaddling above the waist.

Daytime sleep and wake periods of ten swaddled infants were periodically recorded by their mothers. The babies were swaddled above the waist for the first four days of the second, third and fourth months of life. During the next four days of the same months, the same infants were monitored with no swaddling. Comparison of the two sleep situations (swaddled and unswaddled) demonstrated that the increase in the total daytime sleep was statistically significant when the baby was loosely swaddled above the waist.

Ectopic thoracic kidney.

A five-month-old female infant was hospitalized for bronchopneumonia. Ultrasonography and other studies demonstrated the presence of an ectopic thoracic kidney with normal anatomical structures.

Diluted yogurt (ayran) versus water in dissolving oral rehydration salts.

Seventy-six children with gastroenteritis were treated with oral rehydration salts dissolved in ayran (diluted yogurt), and eighty patients were treated with oral rehydration salts dissolved in water. The patients whose ages ranged between three and twelve months accepted both solutions equally. However, the acceptance of the ayran-based solution was significantly greater than WHO's salt solution in the patients whose ages ranged between one and four years. It is proposed that ayran be used to dissolve oral rehydration salts in the treatment of diarrhea since it is more palatable and easily acceptable by children.
