Pharmacokinetics of 5-methyltetrahydrofolate.

The pharmacokinetic behavior of the reduced folate coenzyme, 5-methyltetrahydrofolate, was studied in the rat. Following oral administration the coenzyme was well absorbed from the intestinal tract and was bound to serum proteins. Plasma disappearance occurred in two exponential phases with a t1/2 alpha of 23.5 min and t1/2 beta of 8.5 hr. 5-Methyltetrahydrofolate appeared to be readily taken up by the tissues and was excreted in the urine primarily in the initial 4-8 hr. with minimal degradation in the process.

Pancreatic carcinoma. Survival following detection by ultrasonic scanning.

The survival of 28 patients with pancreatic cancer was studied following initial detection of this malignant neoplasm by ultrasonic scanning. By ultrasound examination, 24 patients had an abnormality, and 21 had a demonstrable mass. Twenty-seven patients are now deceased, and the overall survival ranged from eight days to 24 months (mean, 6.1 months). The results of this study indicate that diagnosis by ultrasonic scanning had no effect on the survival of patients with pancreatic carcinoma.

Intestinal function and morphology in strongyloidiasis.

Divergent available information on the capability of Strongyloides stercoralis to cause malabsorption prompted a long-term observation in which the nutritional state of the subjects was carefully defined. In spite of moderate to severe symptoms, well nourished patients, even with segmental jejunitis, did not show malabsorption. All patients presenting this parasitic infection with concomitant malnutrition showed absorptive defects. Abnormal absorption persisted in spite of parasitic cure when malnutrition was not immediately corrected, and disappeared with correction of the malnutrition even if parasitic infection was allowed to continue. The present experience indicates that the malabsorption syndrome seen in some cases of S. stercoralis infection is secondary to the concomitant malnutrition and not to the parasite per se.
