THE mucociliary transport mechanism is responsible for the clearance of inhaled particulate matter from the upper and lower respiratory tract. Dysfunction of this mechanism may result from defective cilia or from abnormal mucous secretion. A deficiency of ...

STUDIES directed at preservation of ischemic myocardium have focused almost exclusively on limiting tissue necrosis. Animal studies suggest that this approach will benefit only the group of patients in whom intervention is instituted within hours of the ...

EVIDENCE for a genetic role in the pathogenesis of duodenal ulcer includes an increased frequency of the disease in first-degree relatives of patients,¹ a greater concordance for duodenal ulcer in monozygotic than in dizygotic twins,² and an increased ...

THERE is mounting evidence of a disintegration of public support for medical education, or at least for the mechanisms of institutional support currently provided by the federal government. The prevailing consensus of the 1960's and early 1970's — of a "...

MODERN radiologic technics of urography often detect asymptomatic renal masses. Even though occult renal masses are now found more frequently, there is no generally agreed upon protocol for distinguishing benign lesions, such as simple cysts, from renal ...

HYPOSPADIAS is a common anomaly of the urogenital system. The prevalence rate reported by various birth-defect monitoring programs shows a rather wide variation, ranging from about five per 10,000 to about 30 per 10,000 births. During recent years ...

MODERATE gastric hypersecretion is not uncommon after massive small-bowel resection,¹ though it may be temporary.² We speculated that, in patients with the short-bowel syndrome, increased duodenal acid and volume loads might impair digestion and ...

GASTRIC acid hypersecretion after massive small-bowel resection is transient, and its magnitude is proportional to the length of intestine removed.^{1 2 3 4} Peptic ulceration with hemorrhage and perforation, malabsorption due to inactivation of pancreatic ...

It has long been suspected that genetic factors play an important part in duodenal-ulcer disease because the incidence is increased among first-degree relatives.¹ However, until now, no strong genetic marker for the disease had been identified. It has ...

Large-scale support of biomedical research in schools of medicine began in the post-World War II era. The vast benefits in scientific discovery are well known. It is probably also fair to say that most medical faculties believe that the net effect of ...

To the Editor: A simple, unidirectional, leukocyte migration-inhibition assay has been described¹ that can test the serum of patients with cancer for substances with lymphokine-like activity. This technic employs non-separated peripheral leukocytes from ...
