Gonadal dosimetry and spermatogenic activity was monitored in patients given radiation therapy (RT) after unilateral orchiectomy for seminoma. The RT given was, with minor variations, 3200 rad in 16 fractions in four weeks to the para-aortic and ipsilateral pelvic inguinal lymphatics in order to include the orchiectomy scar. The incidental amount of(More)
Blood concentrations of thiamin, biotin, nicotinates, pantothenates, folates, riboflavin, vitamins A, B6, B12, C, E, beta-carotene and choline were analyzed in healthy animals (23 horses, 25 dogs, and 29 cats). B-Complex vitamins and choline also were analyzed in the liver of the dogs and cats. Vitamin concentrations in the blood and livers of dogs were(More)
Vitamins B12, B6, biotin, folate, thiamine, riboflavin, pantothenate, and nicotinate were determined in maternal and fetal blood and placental tissue of normovitaminemic and hypovitaminemic mothers who disclaimed supplemental vitamin intake during pregnancy. No biotin or pantothenate deficits were observed in the gravidas. Hypovitaminemic mothers(More)
Removable Iridium-192 implants provided a dose of 10 Gy/day or 41.5 cGy/hr at 0.5 cm from the center of 1.0 cm diameter tumors. The total radiation (x) alone was 20, 40 or 60 Gy, representing 2, 4, or 6 days of continuous radiation. The doses used for the combined treatments at elevated temperatures were 10, 20 or 30 Gy. The local tumor hyperthermia (LTH)(More)
The 11 patients in this study who received incidental gonadal irradiation from clinical therapy all became aspermic within 8-34 weeks following treatment. The estimated gonadal dose was 118-228 rads. Five of these patients have shown recovery of spermatogenesis; 3 of these have reached fertilizable concentrations. Recovery of semen sperm was noted at 44-77(More)
Vitamins B6 and B12, biotin, folates, riboflavin, nicotinate, pantothenate, biopterin, and vitamin C (l-ascorbate) were assayed in Poteriochromonas stipitata, Euglena gracilis, and Tetrahymena thermophila cells grown in defined media and in spent culture supernatants. P. stipitata and E. gracilis synthesized, stored and excreted folates (mainly as(More)
