Müllerian aplasia associated with maternal deficiency of galactose-1-phosphate uridyl transferase.

The activity and electrophoretic pattern of galactose-1-phosphate uridyl transferase (transferase), a key enzyme in galactose metabolism, were analyzed in four patients with Müllerian aplasia (Rokitansky-Küster-Hauser syndrome) and their mothers. Mothers of two of the patients had genetic variations of their transferase enzymes with activities below the normal range. Affected daughters from these two mothers also had genetic variations of the transferase enzyme. In one of the patients whose Müllerian aplasia had been diagnosed 15 years previously, premature ovarian failure developed. These case reports suggest a possible association between errors of galactose metabolism, Müllerian aplasia, and premature menopause--an association that is supported by a rodent model in which female offspring of mothers fed a high-galactose diet were born with reduced oocyte numbers and delayed vaginal opening.

May-Hegglin anomaly in pregnancy. A case report.

The May-Hegglin anomaly is a rare autosomal dominant platelet disorder that can be associated with significant bleeding. We treated a patient for pregnancy complicated by the May-Hegglin anomaly and a complete placenta previa.

Monocyte chemotaxis mediated by formyl-methionyl-leucyl-phenylalanine conjugated with monoclonal antibodies against human ovarian carcinoma.

Availability of a chemically defined chemoattractant (fMLP) and of appropriate monoclonal antibodies may permit local manipulation of the inflammatory response to human tumors. fMLP has been conjugated with two monoclonal antibodies (OC125 and OC133) which react with human ovarian carcinomas. Conjugates retained the ability to bind to a human ovarian carcinoma line (OVCA433) judged by indirect immunofluorescence and by radioimmunoassay. The fMLP conjugate was maximally chemotactic for human blood monocytes and human peritoneal macrophages at protein concentrations of 300-900 micrograms/ml. Conjugates stimulated chemotaxis rather than chemokinesis. After incubation with an fMLP-antibody conjugate, antigen positive OVCA433 cells released chemotactic activity and attracted monocytes in vitro, whereas an antigen-negative ovarian cell line failed to do so. As monocytes can be important effectors of antibody dependent cell mediated cytoxicity, fMLP conjugates might increase monocyte concentrations at tumor sites and potentiate serotherapy for certain human neoplasms.

The effects of hormone replacement therapy on antithrombin III and protein C levels in menopausal women.

OBJECTIVE: To determine if menopausal women taking estrogen with and without progestin are at increased risk for thrombotic disease as evidenced by decreased levels of antithrombin III and protein C. DESIGN: A case controlled study. SETTING: General community in southeastern New Hampshire. PARTICIPANTS: One hundred seventy-one healthy women aged 38 to 65 years. Women were defined as premenopausal if follicle stimulating hormone levels were < 40 mIU/ml and menopausal if follicle stimulating hormone levels were > 40 mIU/ml. Menopausal women were subdivided according to hormone replacement therapy status; women not taking estrogen or progestin, and women taking estrogen with and without progestin for at least 1 year. MAIN OUTCOME MEASURES: Significant differences in antithrombin III and protein C levels. RESULTS: Premenopausal women had significantly less antithrombin III than menopausal women not taking hormone replacement therapy. Premenopausal women had significantly less protein C than menopausal women taking estrogen for at least 1 year with and without progestin. CONCLUSION: Estrogen taken for at least 1 year with and without progestin by menopausal women will not increase the risk of thrombotic disease by lowering the levels of antithrombin III or protein C. On the contrary, estrogen is associated with an increase in circulating levels of protein C in menopausal women, and could create a protective effect not seen in premenopausal women or menopausal women not taking estrogen therapy.

Expression of Na(+)-H+ exchanger isoforms NHE1 and NHE3 in kidney and blood cells of rabbit and rat.

Increased peripheral blood cell Na-H exchange (NHE) and erythrocyte Na-Li countertransport activity have been reported in hypertension and diabetic nephropathy and correlated with increased activity of the renal brush border Na-H exchanger. A relationship between cation exchange activities of blood cells and renal brush border membranes might exist if both were mediated by the same NHE isoform. We generated isoform-specific antibodies to compare the expression of NHE1 and NHE3 in peripheral blood cell membranes and renal cortical membrane vesicles. An NHE1-specific monoclonal antibody reacted with a 199- to 110-kD protein in basolateral membrane fractions isolated from rabbit and rat kidney. NHE1 protein expression was also detected in erythrocytes, platelets, and lymphocytes isolated from rabbit and rat. Two polyclonal antisera generated against nonoverlapping portions of NHE3 reacted with proteins of 82 and 85 kD in brush border membrane fractions isolated from rabbit and rat kidney, respectively, but failed to detect NHE3 expression in blood cells. These data do not support the hypothesis that Na-H exchanger of Na-Li countertransport in blood cells takes place via the renal brush border membrane NHE isoform, namely NHE3.
