Alteration of consciousness via diverse photo-acoustic stimulatory patterns. Phenomenology and effect on salivary flow rate, alpha-amylase and total protein levels.

Long-term photo-acoustic stimulation is used for the induction of altered states of consciousness for both therapeutic and experimental purposes. Long-term photo-acoustic stimulation also leads to changes in the composition of saliva which have a key contribution to the efficiency of this technique in easing mucosal symptoms of oral psychosomatic patients. The aim of this study is to find out whether there is any cumulative effect of repeated stimulation and whether there are any detectable differences between diverse stimulatory patterns of long lasting photo-acoustic stimulation on the phenomenology of the appearing trance state and on salivary secretion.

Neurochemical diagnosis of Alzheimer's dementia by CSF Abeta42, Abeta42/Abeta40 ratio and total tau.

Cerebrospinal fluid (CSF) concentrations of amyloid beta peptides ending at positions 42 and 40 (Abeta42 and Abeta40, respectively), and total tau (tTau) protein were measured by ELISA in order to compare their accuracy in discriminating patients with Alzheimer's disease (AD, n = 22), non-Alzheimer dementia (nAD, n = 11) and control subjects (CON, n=35). As compared to the other groups, the concentrations of Abeta42 and tTau were decreased (P<0.001) and increased (P<0.

[Effects of photo-acoustic stimulation combined with hypnotherapy on saliva secretion. A pilot study].

Effect of photo-acoustic stimulation on the flow rate and protein concentration of whole saliva was investigated. 10 medical students' and 11 edentulous patients' salivary volume and protein concentrations were measured before, during, and after stimulation. The flow rate of the students' group was significantly higher (p < or = 0.

[Modification of the photo-acoustic stimulation in the psychotherapy of oral psychosomatic patients. Preliminary experiences].

The possible use of a modified photo-acoustic stimulation technique was investigated in the explorative part of the psychotherapy of atypical oro-facial pain patients (n = 20; 13 females, 7 males; age between 39-59; psychiatric diagnostic categories in ICD-10: F41.2, F45.1) Since the stimulatory effects of this method cause difficulties to induce free imaginations, previously the main indication of this technique was the ego-strengthening of the patients, to help them to recognise and to verbalise emotions.
