[The structure of myocardial nerve plexus of human auricle of the right atrium and its relation to myocardial ischemia, functional status of the heart, and age].

The aim of this study was to investigate and evaluate morphometrically the relationship between changes in the structure of myocardial nerve plexus of the right atrium auricle and myocardial ischemia, parameters reflecting functional status of the heart, and age. A total of 56 females and males aged 20-94 years were investigated. Ischemic heart disease group consisted of 39 persons (their mean age was 63.

Innovative non-invasive method for absolute intracranial pressure measurement without calibration.

A new absolute ICP (aICP) measurement method was designed which does not need calibration. In this study we compared a new method with invasive aICP method in ICU on the patients with closed severe traumatic brain injury. A new method is based on two-depth TCD technique for aICP and external absolute pressure aPe comparison using the eye artery (EA) as natural "balance".

Psychosocial factors at work and myocardial infarction among men in Kaunas, Lithuania.

Objectives: The association between job demand and job control and first nonfatal myocardial infarction was studied among the 25- to 64-year-old male population in Kaunas, Lithuania.

Methods: A translation of the Swedish version of the demand-control questionnaire was used. Both psychosocial work characteristics as independent risk factors and the possible effects of traditional risk factors (smoking, arterial hypertension, overweight) were analyzed in a case-control study among 203 men diagnosed in 2001-2002 with a first nonfatal myocardial infarction (cases) and 287 men randomly selected as controls.

Morphometric study of age-related changes in the human intracardiac ganglia.

The present study was performed in order to determine morphological age-related changes of the human intracardiac ganglia. Paraffin sections of 40 ganglia from infants, adult and aged human hearts were stained with Picro-Mallory method. The ganglia area, nerve cell (with clearly visible nucleolus) area, neuron soma long axis length, perimeter, area of neuronal nuclei and neuron soma form factor were measured with the aid of computer images analyzing program "Sigma Scan Pro 5.
