Batroxobin-induced clots exhibit delayed and reduced platelet contractile force in some patients with clotting factor deficiencies.

Thrombin causes platelet activation via multiple pathways, and deficient thrombin generation reduces platelet contractile force (PCF) during clot retraction. We hypothesized that PCF in blood samples from clotting factor-deficient patients would be diminished due to delayed or deficient thrombin generation. Blood samples from patients with fibrinogen, and factor V, VII, VIII, IX, X, XI and XIII deficiencies were compared to samples from normal controls.

Surgical therapy and radiotherapy for carcinoma of the esophagus. Treatment results in 195 patients.

Between 1963 and 1986, 195 patients with carcinoma of the esophagus were seen in the Department of Radiation Oncology at the University of Southern California School of Medicine. Of these 195 patients, 137 had unresectable or inoperable tumors and received radiotherapy. A combination of radiotherapy and surgical therapy was used in 46 patients, 9 patients were treated with surgery alone, and three with chemotherapy alone.

Follicular fluid inhibin activity and steroid levels in ovarian tissue obtained at autopsy from human infants from 18 to 200 days of age.

The ovaries of 25 human infants from 18 to 200 days of age were obtained at autopsy, and their follicular fluid was subjected to measurement of inhibin activity, estrogen, progesterone, androstenedione, and testosterone. Significant inhibin activity was present in all samples of follicular fluid (charcoal-treated) (138 +/- 19 U/10 microliter follicular fluid; 10,545 +/- 2758 U/ovary). There was a tendency for greater inhibin activity, follicular volume, and estrogen in infants from 18 to 59 days than in older infants.
