Interdependence between Zn and Cu serum concentrations and serum immunoglobulins (IgA, IgM, IgG) in liver diseases.

The object of this study was to find out, by means of statistical-mathematical methods, whether the serum concentrations of Zn and Cu had a role in the interrelation among immunoglobulins IgA, IgM, IgG in four groups of subjects with various forms of liver diseases. It was found that the correlation structure between IgA, IgM, IgG and the serum concentration of Zn or Cu were different in the four types of diseases studied, and also that of these two metal ions, Zn was the most important, influencing the interdependence between the immunoglobulins in the active forms of disease.

Study of interrelationship between Zn, Ca and Mg seric concentrations in healthy subjects comparatively with diverse forms of cancer.

The interdependence between the serum Zn, Ca, Mg concentrations was studied in a group of healthy subjects comparatively with a group of patients with various form of cancer. It was found that it is significant difference between the control group and the groups of cancer patients, which shows that the carcinogenic processes disturb the concentrations of these metallic ions, not only quantitatively but also the interdependence between them.

Comparison of risks in cardiovascular diseases.

The paper presents the estimations of the short-time and the long-time (10 years) risks of developing a cardiovascular disease (CD). The standard risk factors considered were: age, deviation from the ideal weight, number of cigarettes smoked per day, level of serum cholesterol and systolic blood pressure. The cardiovascular diseases likely to be induced by these risk factors were: myocardial infarction, angina pectoris, ischemic heart diseases and stroke.

Changes of circulating immune complexes in the serum and CSF of patients with multiple sclerosis.

The level of circulating immune complexes (CIC) was studied before and after treatment in a group of 86 patients with multiple sclerosis (MS) (36 males and 50 females) ranging in age between 20 and 30 years and in 32 controls. CIC determinations were performed both in the serum and in the CSF, using the method of precipitation in polyethylene glycol (PEG). In 61.
