Treatment of 29 cases of chronic lymphedema of various origins, mostly of the lower limbs, by manual lymph drainage massage resulted in significant changes of neurohormone excretion in the urine, whereas the secretion of 17-KS, thyroxine, minerals, and creatinine was not significantly changed. Comparison of the values of urinalysis before and after manual lymph drainage of the patients showed the following changes: 17-KS; -3.5% (non significant); 17-OH: -31% (significant); adrenaline: +50% (significant); noradrenaline: +19% (significant); serotonin: -22% (significant); 5-HIAA: +21% (significant); histamine: +129% (highly significant); thyroxine: -17% (nonsignificant); creatinine: -17% (nonsignificant); sodium: -1% (nonsignificant); potassium: -14% (nonsignificant). The corresponding values for ten controls were all non significant. These findings underline the importance of adrenaline and noradrenaline release by manual lymph drainage, which improves circulation. On the other hand, our results indicate the involvement of histamine and perhaps of serotonin in lymphedema formation, and suggest a combination of manual lymph drainage massage with antihistamine and antiserotonin treatment.

(1) A plethysmographic method has been deviced which measures oedema of the muzzle and neck with high accuracy. (2) Acute lymphostatic oedema of the muzzle and neck was induced by ligation of the cervical lymph glands. (3) By the treatment with various vitamins and vitamin-like substances on the one hand and by massage on the other a statistically significant protection can be achieved against acute lymphostatic oedema.
