[The effect of fominoben and oxyethyltheophylline in combination on pulmonary function and pulmonary hemodynamics in chronic-obstructive diseases of the airways (author's transl)].

Mechanics of breathing, gas exchange and pulmonary hemodynamics were investigated in 10 patients with chronic-obstructive lung diseases before and after treatment with oral doses of 160 mg 3'-chloro-2'-(N-methyl-N-[(morpholino-carbonyl)methyl]-aminomethyl)benzanilide hydrochloride (fominoben, Noleptan) and 300 mg oxyethyltheophylline given three times daily. The data of lung function showed a slight decrease of airway obstruction during the treatment. Hyperinflation of the lung, restriction, gas exchange were not significantly changed on the average. The main effect was an improvement of pulmonary hemodynamics: the pathologically increased mean pressures in the pulmonary artery were normalized after treatment.

Changes of the CO-diffusing components of the lung in patients with coronary artery disease (author's transl).

In 32 patients with angiographically proved CAD the diffusion parameters of the lung (intracapillary pulmonary blood volume, Vc, and diffusion capacity of the alveolo-capillary membrane, Dm, respectively the reciprocal value membrane resistance) were measured. As reference the pre-a-LVDP was used, as it represents more adequately than the LVEDP the pressure acting on the alveolo-capillary membrane. There was a significant positive correlation between the Vc and the pre-a-LVDP as well as a highly significant positive correlation between the diffusion resistance of the alveolo-capillary membrane and the pre-a-LVDP. This corresponds to a pulmonary congestion with an increase of Vc and an interstitial edema with an increase of the diffusion resistance of the alveolo-capillary membrane. The Dco may be unchanged in spite of a marked increase of LVDP, since the decrease of the membrane component is accompanied by an increase of the blood component of diffusion. Only the differentiation of the CO-transfer in its components Vc and Dm gives an information about changes of the hemodynamics in CAD.
