“…22 These differences have been suggested to be attributable to differences in blood flow. 23,24 The greater absorption rate following injection into the cervical muscle, combined with the possibility that injections may have been intermuscular as opposed to IM, may help account for the low number of lesions in the present study.…”

“…No entanto, apesar dos relatos da boa absorção da vitamina E quando administrada por via intramuscular, a hidrólise do DL-α-tocoferol em sua forma ativa no fígado é bastante lenta (Newmark et al 1975), retardando a viabilização de grandes quantidades da forma ativa desse elemento para o organismo, o que pode ter contrubuido para os resultados insatisfatórios observados nesse estudo. Cabe ressaltar também que existe a possibilidade de precipitação da suspensão de DL-α-tocoferol no local da injeção (Hidriroglou 1996), relacionada principalmente com a variação da vascularização no local das inoculações, o que afetaria o fluxo de sangue, ou a taxa de difusão da vitamina E administrada por via intramuscular (Bederka et al 1971).…”

“…In rat muscle, there was a 10-fold difference in clearance rates of labeled carbohydrates, with molecular weight ranging from 182 to 90,000. However, for small molecules, the absorption rate is similar and is limited by blood flow (Sund and Schou, 1964;Bederka et al, 1971). It appears that molecules of low molecular weight are primarily absorbed via the capillaries, while molecules having relatively higher molecular weight are absorbed primarily via lymph vessels (Barnes and Trueta, 1941).…”
