[Evaluation of lumbar tap test combined with mean cerebral blood flow measurement and electroencephalographic topography on idiopathic normal pressure hydrocephalus patients].

Purpose: To improve the diagnostic precision of the lumbar tap test (LTT).

Subjects And Methods: Thirty one patients (mean age, 65.4 years; male to female ratio, 12:19) suspected of having idiopathic normal pressure hydrocephalus (INPH) were used in the study.

Nucleoprotamine diet derived from salmon soft roe protects mouse hippocampal neurons from delayed cell death after transient forebrain ischemia.

The nutritional benefits of nucleoprotamine (NP), the main component of fish soft roe, have been rarely addressed. In the present study, the preventive effect of oral supplements of nucleoprotamine and its derivatives, DNA and protamine (PT), extracted from salmon soft roe, on survival rate and hippocampal cell death induced by transient brain ischemia, was evaluated in mice. Artificially formulated nucleoprotamine-free (NF) diet with/without nucleoprotamine, DNA or protamine was fed orally.
