Sadržaj minerala u kostima mijasteničara

Bone mineral content (BMC) was measured in 23 patients with myasthenia gravis using the 241Am gamma ray attenuation method. Measurements were performed in the proximal (BMC6) and distal (BMC1) parts of the forearm, i.e. at 6 and 1 cm distance from the styloid process of the ulna in supine position. At 6 cm from the styloid process the bone is mostly compact, whereas at 1 cm distance it is mostly trabecular. The results were compared with the BMC values in age and sex matched controls. No signs of major bone loss were noticed in any of the myasthenic patients examined in spite of prolonged administration of fluorocortolone.Sadržaj minerala kosti (BMC) podlaktice mjeren je metodom atenuacije (gašenja) gama zraka 241Am u 23 pacijenta (18 žena i 5 muškaraca). Sadržaj minerala u kosti određivanje u proksimalnom (BMC6) i distalnom (BMC1) dijelu podlaktice. Rezultati mjerenja uspoređivani su s BMC vrijednostima odgovarajućih dobnih skupina normalne populacije. Nisu zapaženi znakovi značajnijeg gubitka kosti kod osoba oboljelih od mijastenije gravis unatoč produženoj terapiji fluorokortolonom
