The effect of chronic feeding (3-4 wk) of the hydrophobic surfactant, Pluronic L-81, on the lymphatic transport of triglyceride and cholesterol was studied in rats with thoracic duct fistula. A lipid emulsion containing [3H]triolein (13.3 mM), [14C]cholesterol (2.6 mM), phosphatidylcholine (2.9 mM), sodium taurocholate (19 mM), with 0.17 mg/ml(More)
Lymph fistula rats were used to determine the acute effects of the hydrophobic surfactant, Pluronic L-81, on lipid transport by the small bowel. Animals were infused intraduodenally with a lipid emulsion containing [3H]triolein and Pluronic L-81, and the rate of intestinal transport of absorbed lipid into lymph was studied using liquid scintillation(More)
Digestion of triglyceride in the intestine results in the production of 2-monoglyceride and fatty acid. Phosphatidylcholine is hydrolyzed in the lumen to form lysophosphatidylcholine before its absorption. These digestion products are absorbed by the enterocytes through simple diffusion. In contrast, cholesterol absorption seems specific and is energy(More)
The cherry-red spot in the fundus as a sign of what is now known as Tay-Sachs disease was first described by Tay in 1881 (1). The first clinical and pathological description of the condition was reported by Sachs in 1887 (2). The similarity between the morphologic and retinal changes in this condition and Niemann-Pick disease led Pick and Bielschowsky (3)(More)
The patient-physician relationship has undergone major and increasingly rapid changes in the past 40 years. It has moved from a relationship based on physician paternalism, through one of patient autonomy, to one where the patient and the physician's authority and control over the patient's care are facing significant threats from outside sources.

In order to evaluate the source and course of gastrointestinal bleeding in patients with established renal insufficiency, we reviewed data on 40 patients with renal failure and gastrointestinal bleeding seen over 2 yr. A randomly selected control group of 39 patients without renal failure was used for comparison. Medical records of our University Hospital(More)
