        Herget J, Kuncova M, Havrankova J, Palecek F.

        In male rats, pulmonary hypertension was found 9, 17 to 18, and 30 wk

        after an intrapulmonary injection of 50 mg quartz dust suspended in

        saline. Pulmonary arterial blood pressure increased progressively with

        time, and in the oldest group, the weight of the right heart ventricle

        was increased.
