Abstract: The dose-response curves of the central and peripheral airways to intravenously injected nicotine were studied in 55 anesthetized dogs. With intact vagi, nicotine caused a dose-dependent increase in central airway resistance (Rc) similar to the increase in peripheral airway resistance (Rp) at concentrations ranging from 4 to 64 micrograms/kg. However, the responses of both Rc and Rp fell progressively when sequential doses of nicotine greater than 256 micrograms/kg were administered. With intact vagi and the administration of propranolol, there was a greater increase in Rp than in Rc at a nicotine dose of 64 micrograms/kg (P less than 0.05). With vagotomy, the responsiveness of both central and peripheral airways to nicotine decreased with doses of nicotine less than 64 micrograms/kg, but with doses of nicotine greater than 256 micrograms/kg the suppressive effect of nicotine on both Rc and Rp was less than that seen with intact vagi. Under conditions in which the vagi were cut and atropine administered, the responsiveness of nicotine was even further depressed. Combinations either of atropine and chlorpheniramine or atropine and phenoxybenzamine also completely blocked reactions to nicotine. Additionally reactions to nicotine were completely blocked by hexamethonium. These results suggest that nicotine increases both Rc and Rp mainly through a vagal reflex and stimulation of the parasympathetic ganglia.

Abstract: Torsional deformity should be localized, quantitated, and usually managed by "observation," an approach that is set forth in detail in this article. Shoe modifications and daytime braces are inappropriate. Night splints or operative procedures are rarely indicated.

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.
