From an epidemiological point of view, there are no certain links with country of origin or race; knowledge of the disease's etiology is equally limited.

Effect of an inhibitor of PGE (flurbiprofen) on colony growth from normal and leukemic peripheral leukocytes in basal conditions and in presence of testosterone or cortisol.

The Authors have controlled the colony growth in coltures from peripheral leukocytes of normal subjects and from patients with CML and AML. The cultures were prepared on double agar layer in basal conditions and after adding flurbiprofen and/or cortisol and/or testosterone. The exam of the plates has shown a light similar stimulating activity on the growth of all substances separately considered, with and evidence ability of flurbiprofen of potentiate the action of the two hormones, both in coltures from normal and leukemic peripheral leukocyte CFU-GM.

[Penbutolol and arterial hypertension].

Penbutolol has proved particularly effective and suitable for the treatment, even on a long-term basis, of recently developed hypertension, especially in its hyperkinetic forms. The drug produces minimal side effects, is well tolerated and gives an early therapeutic response. In addition penbutolol does not cause any significant alterations in the biohumoral parameters of the patients treated and is ideal for combination with dihydralazine, reserpine and dihydrochlorotiazide in the treatment of more stubborn cases, making it possible to reduce the doses of the other drugs without causing bradycardia.
