[A case of acute eosinophilic pneumonia induced by inhalation of acetylene].

Numai utilizatorii înregistrați pot traduce articole

A 17-year-old high school student, while carrying out soldering one morning, inhaled 100% acetylene, and experienced nausea and bilateral lower limb numbness several hours later. In the evening his symptoms worsened, dyspnea followed, and the patient was referred to our hospital the next day. On

Pulmonary tissue volume measured by acetylene rebreathing under artificial ventilation.

Numai utilizatorii înregistrați pot traduce articole

OBJECTIVE In order to evaluate the pulmonary congestive state of patients being mechanically ventilated, an acetylene rebreathing method was employed. Measurement of pulmonary tissue volume by the acetylene (C2H2) rebreathing method was performed in 15 patients under artificial ventilation including

Pulmonary parenchymal tissue volume measurements in graded degrees of pulmonary edema in dogs.

Numai utilizatorii înregistrați pot traduce articole

We investigated the accuracy and the sensitivity of a modification of the acetylene inhalation technique for the determination of lung tissue volume (Vt) during various grades of hemodynamic pulmonary edema in 23 dogs. After base-line acetylene measurements were obtained, intravascular driving force

Pulmonary tissue volume in dogs during pulmonary edema.

Pulmonary tissue volume (Vt) and pulmonary capillary blood flow (Qc) were measured in anesthetized dogs by analyzing end-expiratory concentrations of dimethyl ether (DME), acetylene (C2H2), and sulfur hexafluoride during a 30-s rebreathing maneuver. Vt was compared to the postmortem lung weight of

Efficient synthesis of the first betulonic acid-acetylene hybrids and their hepatoprotective and anti-inflammatory activity.

Numai utilizatorii înregistrați pot traduce articole

The Sonogashira reaction can be applied for the preparation of acetylenic derivatives of betulonic acid where the triterpenoid moiety can serve as either the halo- or the acetylenic component. This reaction opened access to the first derivatives of betulonic acid containing either the arylethynyl

Rebreathing lung tissue volume of sheep with normal and edematous lungs.

Numai utilizatorii înregistrați pot traduce articole

To determine the accuracy of measurements of lung tissue volume (Vlt) by rebreathing acetylene in normal and edematous lungs, we compared gravimetric values of total lung weight (Ql) and extravascular lung water (Qwl) with Vlt in anesthetized control sheep (C) and sheep with hydrostatic pulmonary

[Effect of diffusion limitation on gas exchange in the lung--analysis in oleic acid-induced lung injury].

Numai utilizatorii înregistrați pot traduce articole

To assess the effect of diffusion limitation on gas exchange in injured lungs with non-cardiogenic pulmonary edema, an experimental model of acute lung injury with alveolar flooding was produced in six mongrel dogs by intravenously injecting oleic acid at 0.06 ml/kg. The effect of diffusion

Measurement of pulmonary tissue volume and blood flow in persons with normal and edematous lungs.

Numai utilizatorii înregistrați pot traduce articole

We measured pulmonary tissue volume (Vt) and pulmonary capillary blood flow (Qc) by a rebreathing method using two soluble gases, acetylene (C2H2) and dimethyl ether (DME), in 32 normal subjects and 14 patients who had had pulmonary edema. In 18 of the normal subjects, studies were performed at

Pulmonary tissue volume, cardiac output, and diffusing capacity in sustained microgravity.

Numai utilizatorii înregistrați pot traduce articole

In microgravity (microG) humans have marked changes in body fluids, with a combination of an overall fluid loss and a redistribution of fluids in the cranial direction. We investigated whether interstitial pulmonary edema develops as a result of a headward fluid shift or whether pulmonary tissue

Factors affecting tissue volume measurements in normal and edematous dog lungs.

Numai utilizatorii înregistrați pot traduce articole

To characterize further some of the factors affecting lung tissue soluble-gas rebreathing volume (Vlt), we determined the solubility of acetylene in blood and lung tissue, the influence of the presence of pulmonary edema on tissue solubility, the effects of varying tidal volume (VT), and the tissue

Calcium carbide poisoning via food in childhood.

Numai utilizatorii înregistrați pot traduce articole

The fast ripening of fruits means they may contain various harmful properties. A commonly used agent in the ripening process is calcium carbide, a material most commonly used for welding purposes. Calcium carbide treatment of food is extremely hazardous because it contains traces of arsenic and

Design, synthesis, and biological evaluation of linear 1-(4-, 3- or 2-methylsulfonylphenyl)-2-phenylacetylenes: a novel class of cyclooxygenase-2 inhibitors.

Numai utilizatorii înregistrați pot traduce articole

A group of regioisomeric 1-(methylsulfonylphenyl)-2-phenylacetylenes possessing a COX-2 SO(2)Me pharmacophore at the para-, meta- or ortho-position of the C-1 phenyl ring, in conjunction with a C-2 phenyl or substituted-phenyl ring substituent (3-F, 3-OMe, 3-OH, 3-OAc, 4-Me), were designed for

1,4-Dihydroindeno[1,2-c]pyrazoles with acetylenic side chains as novel and potent multitargeted receptor tyrosine kinase inhibitors with low affinity for the hERG ion channel.

Numai utilizatorii înregistrați pot traduce articole

The synthesis of a novel series of 1,4-dihydroindeno[1,2-c]pyrazoles with acetylene-type side chains is described. Optimization of those compounds as KDR kinase inhibitors identified 8, which displayed an oral activity in an estradiol-induced murine uterine edema model (ED50 = 3 mg/kg) superior to
