Quantitative Analysis of images with statistical evaluation of the data of total, catecholaminergic, adrenergic nerve fibers (n. f.) and/or Beta-adrenergic receptors in the haemangiomatous and normal vessels.

QAI results	Haemangiomatous vessels	Normal vessels
Total n. f.	31.4 ± 2.8*	96.3 ± 3.1
Catecholaminergic n. f.	27.6 ± 3.3*	48.3 ± 2.8
Adrenergic n. f.	12.9 ± 2.8*	21.6 ± 3.2
Beta-adrenergic receptors	39.8 ± 3.2*	95.6 ± 3.6

All the results are expressed as C.U. (Conventional Units) ± SEM.

* P < 0.001 versus normal.
