Prostaglandins and the pulmonary circulation

Prostaglandins, 1973
Abstract Prostaglandins (PG) E 1 , E 2 , F 2 α , and A 1 were infused into 15 normal mongrel dogs at doses varying from .04 – 6.0 μg/kg/min. Pressures were recorded from the pulmonary artery, left atrium and femoral artery; pulmonary blood volume and cardiac output were determined using sequential indicator dilution curves from injections into the ...

Pulmonary circulation in the reindeer

Basic Research in Cardiology, 1978
Right heart catheterizations were performed in 56 sessions on 25 reindeer with determinations of blood pressure and oxygen saturation. Cardiac output was calculated from cineangiocardiograms. When the animals were placed in prone position, heart rate was about 50/min, mixed venous blood oxygen saturation 68 to 72%, right ventricular systolic pressure ...

Pulmonary Circulation in Hypoxia

International Journal of Sports Medicine, 1992
Hypoxia constricts the pulmonary vessels. An increase in pulmonary vascular resistance is seen in normal subjects during hypoxic breathing at sea level, in acclimatized lowlanders and in high altitude natives. Hypoxic pulmonary hypertension in all these circumstances is most generally moderate, except in high altitude natives at exercise.

Superoxide in the pulmonary circulation

Pharmacology & Therapeutics, 1999
Superoxide formation in pulmonary tissue is modulated by cytokines, PO2, shear force, and disease states, and can be stimulated by drugs. Superoxide has diverse actions on pulmonary cells, including smooth muscle contraction, interaction with redox enzymes, cell proliferation, and gene transcription.

Pulmonary circulation in embolic pulmonary edema

Bulletin of Experimental Biology and Medicine, 1989
The ultrasonic method was used in acute experiments on cats with open chest under artificial lung ventilation to obtain blood flow in low-lobar pulmonary artery and vein, the blood pressure in pulmonary artery, as well as the left atrial pressure in fat (olive oil) and mechanical (Lycopodium spores) pulmonary embolism.

Pulmonary Circulation at High Altitude

Respiration, 2009
Hypoxia constricts the pulmonary vessels. An increase in pulmonary vascular resistance is seen in normal subjects during hypoxic breathing at sea level, in acclimatized lowlanders and in high-altitude natives. Hypoxic pulmonary hypertension in all these circumstances is most generally moderate, except in high-altitude natives at exercise.
