Cardiovascular surgery in patients with congenital plasma coagulopathies.

From 1978 to 1986, fifteen cardiovascular operations were performed on 13 patients with known congenital bleeding disorders. The patients (10 men and 3 women) had a mean age of 51.1 +/- 3.

Clinical experience in 1040 patients with double-velour knitted Dacron vascular prostheses: With particular reference to dilatation and aneurysm formation.

Recent reports of dilatation and aneurysm formation in Dacron fabric grafts have prompted us to review our experience with 1040 patients who received Meadox-Cooley double-velour knitted grafts over a 47-month period. Bifurcation grafts were used in 398 patients with aorto-femoral occlusive disease and in 203 patients with aortoiliac occlusive disease. Straight tube grafts were implanted in 310 patients with abdominal aortic aneurysms.

COMBINED CORRECTION OF TETRALOGY OF FALLOT AND CORONARY ARTERY OCCLUSIVE DISEASE: CASE REPORT.

A 49-year-old patient with known tetralogy of Fallot for which an aortopulmonary anastomosis (Pott's shunt) had been performed 23 years previously, underwent simultaneous myocardial revascularization for severe coronary occlusive disease and total correction of his congenital anomaly. The operation and postoperative course were uneventful, and he made a full recovery.

Comparative bioavailability of elemental iron powders for repair of iron deficiency anemia in rats. Studies of efficacy and toxicity of carbonyl iron.

The rate of hemoglobin repletion in iron-deficient rats was used to measure the bioavailability of several elemental iron powders added to an iron-free nutritionally balanced chow. We used ferrous sulfate as a standard, highly bioavailable control. Of the several powders, carbonyl iron demonstrated the highest bioavailability.

Fatty acid composition of adipose cells in red and yellow marrow: A possible determinant of haematopoietic potential.

The fatty acid composition of whole bone marrow and that of isolated, disaggregated adipose cells from red and yellow marrow was examined by gas chromatography. Consistent and significant shifts from myristic and palmatic acids (in red marrow) to their respective monounsaturated derivatives myristoleic and palmitoleic acids (in yellow marrow) were found. These differences in the fatty acids correlate with histochemical studies and lend further support to the concept that the composition of lipid in the adipose cells of bone marrow may determine their relative stability in relation to haematopoietic requirements.
