Example Input: Abstract: The plasma concentrations of epinephrine were determined in healthy subjects administered epinephrine by subcutaneous injection of 0.5 mg or inhalation of 1.5 to 4.5 mg (10 to 30 inhalations from a metered-dose aerosol). The absorption of injected epinephrine was variable and in several cases very slow. The individual maximum values for epinephrine in plasma were 4.65 +/- 1.09 (range 0.74 to 8.31) nmol/L, and these maxima were attained 5 to 120 minutes after injection. Inhaled epinephrine was rapidly and dose dependently absorbed. Ten inhalations resulted in 2.72 +/- 0.84 (0.75 to 5.67) nmol/L within 5 minutes and 20 inhalations resulted in 7.19 +/- 1.78 (2.10 to 13.83) nmol/L with rapid increases and maxima within 20 minutes in seven of eight subjects. Gastrointestinal side effects were dose limiting when epinephrine was administered by inhalation. Our results indicate that inhalation of 2 to 3 mg of epinephrine produces rapid increases of epinephrine concentrations in plasma to levels that have previously been demonstrated to counteract bronchoconstriction induced by inhaled allergen in subjects with asthma. Inhalation has several advantages over injection for self-administration of epinephrine, e.g., in patients who are allergic to insect (Hymenoptera) stings. Apart from the absorption being more rapid, the locally high concentrations of epinephrine in the airways should be advantageous, since bronchoconstriction is one of the life-threatening phenomena of the anaphylactic reaction. This route of administration is also simple for the patient.

Example Input: Abstract: The current studies were designed to investigate the effect of calcium channel blockers on chemically induced gastric lesions in rats. Results of this study indicate that pretreatment of male F344 rats with the calcium channel blockers verapamil, diltiazem, or Mg2+ significantly protected against ethanol- and indomethacin-induced gastric lesions as demonstrated by gross and histopathologic evaluation. Treatment of rats with calcium channel blockers before ethanol or indomethacin administration resulted in a significant decline in the mean number of lesions per glandular stomach, the damaged area of the glandular stomach, and the severity of lesions. Calcium channel blockers also caused a significant decline in the incidence of indomethacin-induced gastric lesions, but had no effect on the incidence of ethanol-induced gastric lesions. These results offer the first evidence that calcium channel blockers may play an important role in the protection against chemically induced gastric lesions and thereby offer insight into the mechanism of gastric ulcer formation. It is speculated that this knowledge may prove important in the development of new and improved therapies for the treatment and prevention of gastric ulcers in humans.

Example Input: Abstract: Enhanced clinical awareness of infective endocarditis, along with improved microbiologic methodology and more aggressive surgical intervention, has favorably influenced the outcome of the disease. The evolving nature of infective endocarditis over the past decade is described, as are the changing epidemiologic factors, microbiologic techniques, and echocardiographic contributions in the clinical management of patients with infective endocarditis.
