Estriol-3-sulfate (E3-3S) was assayed in 92 specimens of human breast cyst fluid (BCF) obtained by needle aspiration from women with fibrocystic disease. The concentrations of K+ and Na+ were determined in the same samples. The median concentration of E3-3S in the fluids from premenopausal women under 51 years of age (69 cases) was 4.4 ng/mL. Based on the K+ levels the samples were divided into two groups, above 50 mM (Type I) and below 50 mM (Type II). Correlations were made between the concentrations of the estrogen conjugate and the univalent ions. In the premenopausal women, Type I cysts were associated with above median E3-3S and Type II cysts with below median E3-3S (P less than 0.01). A K+/Na+ ratio of more than one was also related to elevated E3-3S (P less than 0.025). The BCF obtained from postmenopausal women and women older than 50 years tended to be low in E3-3S (median 1.64 ng/mL) and high in K+ but there were too few cases to permit statistical comparisons to be made. Since fibrocystic disease constitutes a risk factor for the development of breast cancer, it will be of interest to determine retrospectively whether any of the above subsets of BCF may be useful in identifying a patient at such risk.

Quantification of the sulfates of 16 alpha-hydroxy androgens that are possible precursors of estriol-3-sulfate in human breast cyst fluid.

The concentration of 16 alpha-hydroxydehydroepiandrosterone-3-sulfate (16 alpha-OHDHAS) was determined in 29 samples of human breast cyst fluid (BCF) and in 15 of these, androst-5-ene-3 beta,16 alpha,17 beta-triol-3-sulfate (A-TriolS) was also assayed. The median value of both was about 100 ng/mL and the ranges were from 1.4 to about 1800 ng/mL. There was a significant association in the values for the two sulfates (p less than 0.05). These concentrations are consistent with a role for 16 alpha-hydroxy androgens as possible precursors for estriol-3-sulfate. The latter is highly elevated relative to other body fluids in BCF. The androgens also correlated directly with the concentrations of K+, an indicator of apocrine proliferation of breast cysts.

Fibrinogen and albumin deficiencies associated with packed red blood cell transfusions.

Fibrinogen content was determined for each of 50 units of citrate-dextrose-phosphate (CPD)-preserved whole blood, packed red blood cells reconstituted with 250 ml. of saline, and packed red cells reconstituted with 250 ml. of purified plasma protein fraction (PPF). The total protein and albumin were measured, by electrophoresis, on each of 10 units of the three varieties of blood. The fibrinogen content of the two types of reconstituted cells was significantly lower than that of whole blood. Although the total protein/albumin content of whole blood and PPF-reconstituted red cells was similar, saline-reconstituted cells were markedly deficient in both total protein and albumin. Low fibrinogen and platelet levels subsequent to transfusion with reconstituted packed red cells can lead to an erroneous diagnosis of disseminated intravascular coagulation. Administration of large quantities of saline-reconstituted packed cells could be an etiologic factor in postoperative interstitial pulmonary edema.
