(3) The functional significance of these early changes in the nodal region is uncertain.
(4) Preservation of dopaminergic and H1 neurotransmission, probably within the blood barrier, is needed to allow the neuroendocrine transduction of cholinergic inputs, whereas the role of 5-HT neurotransmission remains uncertain.
(5) The nature of these infiltrative foci remains uncertain; however, they are unlikely to have been of neoplastic origin and may be due to interleukin-2-induced lymphocytic infiltration.

(8) In 11 patients, the electrophysiological mechanism remained uncertain.
(9) The nature of the cystatin C-immunoreactive substance in some of these vascular lesions is uncertain, but it might conceivably play an additional important role in the pathogenesis of brain hemorrhage in these cases.
