In this article, the thin-shell formulation is applied to efficiently modeling the Stern layer within computational algorithms oriented toward the boundary element solution of the linearized Poisson-Boltzmann equation. The attention is focused on the calculation of the electrostatic potential in proximity to a biomolecule immersed in an electrolyte medium. Following the proposed approach, the Stern layer is made to collapse to a zero-thickness region (two-dimensional surface) with interface conditions linking the electrostatic potential over the molecular and the bulk ion accessible surfaces.

To investigate the beta 2-receptor selectivity of a new beta 2-adrenoceptor agonist, broxaterol, we compared the respiratory and cardiovascular effects of this compound with those of terbutaline and placebo. Twelve asthmatic patients were evaluated in a randomized, single blind, crossover study. A single dose of each study treatment (broxaterol 400 micrograms and terbutaline 500 micrograms was administered with metered dose inhalers.

Drugs that stimulate adrenergic receptors are expected to affect glucose and lipid metabolism. Therefore, it was deemed to be of interest to assess whether the new selective beta 2-adrenoceptor agonist, broxaterol, exerts any metabolic effect. Broxaterol has been evaluated in 21 patients, 18 men and 3 women, aged 34 to 80 years, with a diagnosis of reversible obstructive airways disease.

Fourteen patients with chronic obstructive lung disease (COLD) were studied. All were in a relatively stable clinico-functional state, and bronchospasm was reversible with fenoterol. The study was carried out over 3 days.

169 lung cancer patients were studied and their survival curves analysed after classification according to various parameters (clinical stage using the TNM method, histological type, and morphoradiological type). The resulting tragic picture is further confirmation of the primary importance of prompt diagnosis as well as an appropriate prevention strategy.

The key-points of the physiopathological treatment of chronic pneumogenous respiratory insufficiency are: correction of distribution defects, suitable local adjustment of the ventilation: perfusion ratio, and correction of obstacles to alveolocapillary diffusion. Many drugs can be used to obtain these results; bronchodilators, vasoactive drugs, cortisones, cardiokinetics, antibiotics, analeptics. Reference is also made to oxygen therapy, depletion management (bloodletting and-or diuretics, and their possible mechanisms.
