Time-dependent modifications of N-acetyltransferase (NAT) activity, melatonin content, and tyrosine hydroxylase (TH) activity within the isolated rat pineal over a 72 h of incubation period were studied. Both pineal NAT activity and melatonin content displayed similar decreases after 12 h of incubation, and reached a maximal reduction of 82% or 93%,(More)
Twenty-four h changes in endogenous tyrosine hydroxylase (TH) activity, monoamines and their metabolites as well as N-acetyltransferase (NAT) activity and melatonin content were investigated in the Syrian hamster pineal gland. Both NAT activity and melatonin content exhibited an expected rise 8 h (0400 h) after darkness onset. Pineal dopamine (DA) and(More)
The syndrome known as migraine with cerebrospinal fluid (CSF) pleocytosis is a clinical syndrome of controversial pathogenesis characterized by typical migraine headaches occurring in a fixed period of time along with lymphocyte pleocytosis in CSF which persists during intercritical periods. We present four new cases of this syndrome diagnosed in our(More)
