The results of experimental studies made it possible to draw a conclusion on the reality of cerebral vessels reactivity recovery using drugs with primary neurometabolic activity, in particular, dimephosphone, sermion and pyracetam. The advantages of low-toxic nonauticholinesterasic organic phosphorus compounds among the correctors of regulatory mechanisms of circular provision of the brain are shown.

✓ The cerebral blood circulation time (CT), including the length of the arterial phase, was obtained from rapid serial angiograms in 114 patients with ruptured intracranial aneurysms. The average CT of 7.2 sec, with a mean arterial phase of 3.1 sec, was much longer than the normal average CT of 5.4 sec with its 2.4 sec arterial phase. Longer circulation times were observed with the higher Botterell grades of clinical condition, high arterial perfusion and CSF pressures, and in cases with angiographic evidence of arterial spasm, hematoma, or hydrocephalus. Values of CT greater than 8.0 sec were associated with increased mortality and morbidity and vice versa. The value of the cerebral blood circulation time as a guide to preoperative treatment and to the prognosis of cases of ruptured intracranial aneurysm is suggested.

Cerebral Blood Circulation

Neurohumoral correlations of sleep are considered from three aspects: 1. Metabolism and cerebral blood circulation (CBF, EEG, endocranial pressure, cerebral temperature); 2. Neuromediators and neuropeptides (5-HT, hypnogen neuropeptides); 3. The influence of the sleeping–waking cycle on adeno-hypophyseal secretion rhythms (GH, PRL, LH, TSH). Variations of these parameters can play an important role in the onset of night crises of migraine and cluster headache. Les liens neuro-humoraux du sommeil sont considérés selon trois points de vue: 1. Circulation cérébrale et métabolisme (CBF, EEG, pression endocrânienne, température cérébrale); 2. Neuromédiateurs et neuropeptides (5-HT, neuropeptides hypnogènes); 3. Influence du cycle sommeil-veille sur les rythmes de sécrétion adénohypophysaire (GH, PRL, LH, TSH). Des variations de ces paramètres peuvent jouer un rôle important dans le déclenchement des crises nocturnes de migraine et de céphalée à grappe. Le correlazioni neuroumorali del sonno vengono considerate da 3 punti di vista: 1. Circolazione cerebrale e metabolismo (CBF, EEG, pressione endocranica, temperatura cerebrale); 2. Neuromediatori e neuropeptidi (5-HT, neuropeptidi ipnogeni); 3. Influenza del ciclo sonno-veglia sui ritmi di secrezione adenoipofisaria (GH, PRL, LH, TSH). Variazioni di questi parametri possono svolgere un ruolo importante nello scatenamento delle crisi notturne di emicrania e di cefalea a grappolo.
