Input: Consider Input: Abstract: During a 5-year period, 15 cases of primary gastrointestinal lymphoma, corresponding to 14% of the non-Hodgkin's lymphomas, were diagnosed in a population of 200,000. Most patients had a short duration of symptoms--less than 3 months--and a clinical picture dominated by abdominal pain. All patients were laparotomized and six patients presented with an acute abdomen and were subjected to emergency operations. In seven cases, gastrointestinal malignancy was not suspected preoperatively. The patients were treated with a combination of surgery, cytostatic therapy, and/or radiotherapy. Cases with localized disease had a favorable prognosis, seven of nine patients being alive 31 to 70 months after diagnosis. A statistically significant difference in median survival was also noted between patients with lymphomas of low-grade and high-grade malignancy (70+ vs. 10.5 months).

Input: Consider Input: Abstract: We correlated the level of vitiligo antibodies to the extent of depigmentation in thirty-two patients with vitiligo. Vitiligo antibodies were assayed by protein A-sepharose immunoprecipitation method. Antibodies were present in four of eight (50%) patients with minimal vitiligo (less than 2% body surface involved), in nine of ten (90%) patients with moderate vitiligo (2 to 5% surface involved), and in thirteen of fourteen (93%) patients with more extensive disease (greater than 5% surface involved). The level of vitiligo antibodies in the three groups expressed as a binding index was 2.9% +/- 2.03, 5.6% +/- 2.92, and 8.0% +/- 3.03 SD, respectively. These results suggest that there is a relation between the incidence and level of vitiligo antibodies and the extent of depigmentation in vitiligo.

Input: Consider Input: Abstract: Primary monolayer cultures of human fetal adrenal cells maintained in either lipoprotein-depleted or lipoprotein-supplemented media responded chronically to ACTH treatment with similarly increased steroid secretion. The principal steroid secreted into each medium was dehydroepiandrosterone sulfate. The presence of human low density lipoprotein (hLDL) in the medium enhanced the secretion of nonsulfoconjugated steroids, especially dehydroepiandrosterone. The secretion rate of 11 beta-hydroxyandrostenedione was similar to that of cortisol. In the absence of hLDL, ACTH increased cholesterologenesis to maintain the high rates of steroid secretion. After ACTH treatment, increased accumulation of 3-hydroxy-3-methylglutaryl coenzyme A reductase, a rate-determining enzyme of cholesterol biosynthesis, was found. Immunoblot analysis demonstrated that this enzyme was a 97K protein in human fetal adrenal cells. Interestingly, the content of this enzyme in cells treated with ACTH in lipoprotein-depleted medium was similar to that in adrenal fetal zone tissue. This finding suggests that cholesterologenesis de novo in addition to plasma LDL is important as a source of steroid precursor in vivo in the human fetal adrenal gland.
