title: Stimulating effect of unfractionated heparin and a low molecular weight heparin fragment on the DNA synthesis response of human thymocytes to mercuric chloride.
abstract: The effect of unfractionated heparin and a low molecular weight heparin fragment was tested on the DNA synthesis response of human thymocytes to mercuric chloride. In a concentration of 0.01-0.11 mg/ml, unfractionated heparin somewhat stimulated this response, while the heparin fragment at 11.1 mg/ml gave an evident stimulation of the response and a lower stimulation degree at 1.1 mg/ml.
