Although plasma histamine concentration has been reported to increase after thermal injury in the rat to as much as 100-fold over normal human plasma levels, the pathophysiological significance and relevance to human disease is questionable. Lack of confidence in the rat as a model of histamine-mediated disease is based on reports that normal rat base-line plasma histamine concentration exceeds that of human plasma by 20- to 70-fold. The present study confirms that high concentrations of histamine (20–68.9 ng/ml) are found in rat plasma obtained in an uncontrolled manner; but concentrations are lower (1.17 +/- 0.49 ng/ml) or undetectable in a sensitive radioenzymatic assay when sampling technique and plasma isolation are controlled. The primary cause for falsely elevated values for plasma histamine concentration appeared to be due to manipulation of the rat. Plasma histamine concentration increased within 1 min after thermal injury and the increase was proportional to extent of surface area injured. In contrast to the finding of a single time-related peak of plasma histamine concentration after partial-thickness burn, a biphasic elevation was found after full-thickness injury. Thus the data indicate that normal rat plasma histamine concentration is similar to that of the human and below the reported threshold for modulation of a variety of immune responses. Furthermore, the data support a role for histamine and other mast-cell mediators in the local and systemic responses to injury.

Venous Plasma

1. Venous plasma histamine and catecholamines were measured in stable asthmatic subjects by a recently developed specific and sensitive radioenzymatic assay. 2. Plasma histamine concentrations were significantly elevated in both extrinsic and intrinsic asthmatic subjects, compared with both normal controls and patients with chronic obstructive airways disease. There was no correlation between histamine concentration and severity of airways obstruction, however. 3. Elevated plasma histamine concentrations at rest-5-indicate increased release of mediators from ‘leaky’ mast cells in asthma. 4. Plasma catecholamine concentrations in asthmatic subjects did not differ from normal and there was no correlation with severity of broncho- constriction or with plasma histamine concentration.

1. Arterial and venous whole blood and plasma histamine concentrations and eosinophil and basophil counts were determined in five patients with acute severe asthma who had not previously received steroid therapy, in five who had been maintained on steroid therapy and in a control group of nine patients with acute non-respiratory illnesses. 2. No significant arteriovenous differences were observed for any of these measurements in any of the groups of patients. Significant net loss of arterial histamine does not therefore occur peripherally in acute asthma. 3. When compared with the values for the controls, statistically significant increases were observed, in the group not receiving steroids, for arterial and venous whole blood histamine concentrations, eosinophil counts and basophil counts, and, in those receiving steroids, for the venous basophil counts. 4. When compared with the venous plasma histamine concentration of normal subjects, that of the asthmatic subjects not receiving steroids was significantly raised. 5. The venous plasma histamine concentration of the control group was also significantly higher than that of normal subjects, but less so than in the asthmatic subjects, suggesting that acute illness per se produces an increased plasma histamine concentration. 6. Both groups of asthmatic patients were treated similarly with hydrocortisone and bronchodilators. There was a striking fall in whole blood histamine concentration and in eosinophil and basophil counts, but plasma histamine fell more slowly, especially in those who had not previously received steroids. 7. The mean histamine content of the basophil cell is 0·01 pmol and significant differences in this value did not occur within the various groups or as a result of treatment. The approximate number of molecules of histamine per basophil cell is 6·0 × 109.
