[Ecological monitoring of population mortality in Kaunas micro-districts, 1992-1997].

In Lithuania, the mortality rate is constantly increasing. However, regional differences of mortality rates in a large industrial town were unexplored. The study was carried out in Kaunas, second biggest town of Lithuania with a well-developed industry, as well as high atmospheric air pollution.

[Characteristics of general anesthesia in the investigation of heart electrophysiology].

Investigating electrophysiological properties of the heart under acute experimental conditions, dogs are affected by operative stress because of traumatic surgical manipulations, so investigations are performed under general anaesthesia. Many anaesthetics together with their main function have desintegrating influence on autonomic regulation mechanisms. That is why anaesthetics used during experiments must fullfil such requirement--have minimal influence on autonomic nervous system (ANS) and heart conductivity system (HCS) interaction parameters or to make this influence insignificant.

[Poisoning by chromium and its long lasting detoxication].

Long lasting influence of cumulated Cr provide irreversible damages of vascular walls, organs and their systems. During long lasting treatment most of Cr is removed during the first 20 days through bileric tract and at the same time through the renal tract the Cr amounts decreases because chromium-d-penicilamin complex in hepatocytes induces synthesis of specific chromium-d-penicilamin binding labile protein and they are removed with bile. The levels of essential microelements (Cu and Zn) are maintained at the level of the physiological tolerance during treatment.

[Myocardial protection: which method of cardioplegia is better?].

The remarkable advances in cardiac surgery over the last 50 years have led to the concept of "routine" open heart surgery. The introduction of novel surgical technologies, methods of anesthesiology and intensive care allowing for a reduction morbidity and mortality at perioperative period. The development of intraoperative myocardial protection has been impressive too.

[Trends in the prevalence of risk factors of noncommunicable diseases during 1987-1999].

The trends in the prevalence of hypertension, hypercholesterolemia, overweight and smoking among Lithuanian rural population were assessed from 1987 to 1999. Three independent surveys in 1987, 1993 and 1999 were carried out in five rural regions of Lithuania in random samples of men and women aged 25-64 involving 2695, 1550 and 1838 persons respectively. The risk factors were defined according to the WHO criteria.

[Tracheostomy and prolonged artificial ventilation of patients after heart surgery].

Dysfunction of respiratory system after open heart surgery is one of the main problems in postoperative period. When mechanical ventilation is prolonged because of different causes, tracheostomy is usually performed, but the optimal time is still being discussed. In order to elucidate the influence of tracheostomy to subsequent course of disease we reviewed the indications, frequency and complications of postoperative tracheostomies performed in 1998-2000 in Cardiosurgical clinic after open heart surgery.

[Ischemic stroke and its risk factors after cardiac surgery].

The modern reparative procedures are highly successful in terms of the cardiac outcome; they can be detrimental in regard to the central nervous system (CNS). Perioperative stroke is one of the most serious complications of cardiac surgery. Refinements and advances in surgical techniques, myocardial preservation and anesthesia have led to a decline in morbidity and mortality for cardiac surgical patients.

[Patient satisfaction with the work of the hospital medical personnel].

The article presents the data of patient's satisfaction with the work of nurses and physicians in the hospitals, which belong to Lithuanian Health promotion hospitals network. All nine hospitals of the Lithuanian health promotion hospitals network took part in this study. Altogether 1300 questionnaires were handed out.

The aim of this study was to define the relation between the activity of neurons in this nucleus and changes of the blood pressure in the aorta during the pulse wave. Impulses of 74 pulse-rhythmic neurons, i.

[Procalcitonin: a new infection marker. Its use in intensive care].

In daily routine diagnosis, there are few parameters available to monitor critically ill patients and to control the course of therapy in severe inflammations. There are also few reliable parameters differentiating acute bacterial infection from other types of inflammation. Most of the presently used indicators of the inflammatory response, like body temperature, white cell count, erythrocyte sedimentation rate or C reactive protein are unspecific parameters with changing reliability.

[Effects of mercury on the course of Listeria monocytogenes infection in mice].

Effects of mercury ions on the colonization of mice organs by Listeria monocytogenes were investigated. It was found that single injection of 0.05 LD50 mercury ions has little effect on listeria spreading in mice internal organs.

[Anesthesia used in minimally invasive myocardial revascularization surgery].

As myocardial revascularisation operations without cardiopulmonary bypass are getting more popular, more facts are found about their surgical techniques. However, the questions considering their anesthesia, the protection of myocardium and other are not widely analyzed. The specific features of anesthesia in cardiosurgery, such as methods of ventilation, combination of induction and general anesthesia with epidural anesthesia, usage of cardiac protection and ischemic preconditioning, monitoring, heparin management, usage of drugs, postoperative pain management are given in this article.

[Transmyocardial laser revascularization: a past or future treatment method? (review of the literature)].

Despite the success of current medical and surgical management of ischemic heart disease, a growing number of patients have diffuse obstructive coronary artery disease that is not amenable to coronary artery bypass grafting or catheter based interventions. This problem has stimulated interest in developing alternative therapeutic approaches. The construction of subendocardial channels to perfuse ischemic areas of the myocardium has been investigated since the 1950s.

[The development of mixed emotional and behavioral disorders in children raised in foster care institutions].

The aim of the work was to evaluate the changes brought by time in the psychoemotional state of neglected and abandoned children (exhibiting disturbed social relations), which were displayed in childrens' behavior. The longitudinal research has been carried out by the epidemiological case-control scheme. Two groups of children were examined.

[The psychosocial factors associated with preschoolers' wellbeing in a kindergarten].

The aim of our investigation was to find out how do pre-school aged children felt themselves in kindergarten and what factors their well-being depended on. The survey was carried out in 1999 and 2000. A sample of 631 children aged 6-7 years was interviewed in 12 randomly selected kindergartens of Kaunas.

[Effects of aluminum ions on the mouse protein synthesis in vivo and in vitro].

Impact of aluminium ions on the translation process in mice liver, kidney, skeletal muscle and heart was investigated in vivo as well as on the protein synthesis in liver cell-free translation system in vitro. We find that at early stages of intoxication the effect of aluminium ions on protein synthesis in muscle tissues differs qualitatively from that one in liver or kidneys. Most noticeable aluminium-induced changes of protein synthesis in organs in vivo occur within the first 15-20 h after intoxication.
