TASK DEFINITION: Indicate the presence of numerical data in the abstract (whether numerical data plays a key role in medical records), solely using the information from the abstract.
PROBLEM: Abstract: In chronically catheterized rats hepatic glycogen was increased by fructose (approximately 10 g/kg) gavage (FF rats) or lowered by overnight food restriction (FR rats). [3-3H]- and [U-14C]glucose were infused before, during, and after treadmill running. During exercise the increase in glucose production (Ra) was always directly related to work intensity and faster than the increase in glucose disappearance, resulting in increased plasma glucose levels. At identical work-loads the increase in Ra and plasma glucose as well as liver glycogen breakdown were higher in FF and control (C) rats than in FR rats. Breakdown of muscle glycogen was less in FF than in C rats. Incorporation of [14C]glucose in glycogen at rest and mobilization of label during exercise partly explained that 14C estimates of carbohydrate metabolism disagreed with chemical measurements. In some muscles glycogen depletion was not accompanied by loss of 14C and 3H, indicating futile cycling of glucose. In FR rats a postexercise increase in liver glycogen was seen with 14C/3H similar to that of plasma glucose, indicating direct synthesis from glucose. In conclusion, in exercising rats the increase in glucose production is subjected to feedforward regulation and depends on the liver glycogen concentration. Endogenous glucose may be incorporated in glycogen in working muscle and may be used directly for liver glycogen synthesis rather than after conversion to trioses. Fructose ingestion may diminish muscular glycogen breakdown. The [14C]glucose infusion technique for determination of muscular glycogenolysis is of doubtful value in rats.

PROBLEM: Abstract: Use of the colposcope for vulvar and vaginal examination in four cases of long-standing vulvodynia led to the identification of lesions with an unusual appearance. In the vulvar vestibule, epithelial projections resembling cactus, camel humps or stony colonial pavement were observed. In the vagina, the lesions looked more like cerebral folds. Biopsies of these lesions showed histopathologic changes diagnostic of human papillomavirus infection, scored according to Reid's criteria. In one case, capsid antigen was detected with the peroxidase technique in the nuclei of the superficial cells. Past history and positive findings in the sexual partners of some of the patients suggested long-standing herpesvirus activity in the lower genital tract. In some cases of recalcitrant vulvodynia, colposcopic examination of the vulva and vagina may lead to a viral explanation for symptoms previously considered psychosomatic in origin.

PROBLEM: Abstract: To determine if constituents of cotton plants might play a role in byssinosis by injuring pulmonary epithelium, we added extracts of cotton dust, green bract, and field-dried bract to human A549 and rat type II pneumocytes. Injury was measured as pneumocyte lysis and detachment, and inhibition of protein synthesis. Extracts of cotton dust and field-dried bract produced significant dose- and time-dependent lysis and detachment of both target cells, while green bract extract was less damaging. Extracts treated with polyvinylpolypyrrolidone to remove tannins produced significantly less injury. In contrast, purified 5,7,3',4'-tetrahydroxy-flavan 3,4-diol (THF), a tannin in cotton dust and bract, caused substantial cell damage. Field-dried bract extract and THF also produced dose-dependent inhibition of pneumocyte protein synthesis. Endotoxin levels did not correlate with observed injury. THF added to rat tracheal explants caused epithelial disruption and desquamation, whereas endotoxin did not. Instillation of cotton dust and field-dried bract extract in rat lungs produced disruption of bronchial epithelium and smooth muscle constriction, while polyvinylpolypyrrolidone-treated cotton dust extract produced no injury. These findings suggest that extracts of cotton plants are toxic to alveolar, tracheal, and bronchial epithelium and that THF or other tannins may be the responsible agents.
