[Drug addiction among young students aged 15-21].

The survey was done to compare two groups of young people (aged 15-21) studying in Wroclaw and Olesnica: 60 students who declare to have drugs and 58 students who declare themselves as never having had contact with drugs. Reasons for drug taking were investigated. Social origin, education and financial sources of parents, as well as living standards are not important factors distinguishing drug taking persons from the rest of population.

[Opinions of the role of health promotion in practice of primary care physicians].

Opinions of students of Wroclaw Medical University on the role of health promotion in daily practice of primary care physicians were studied. An agreement was found in opinions that primary care physicians are not properly prepared for health promotion and that they do not get appropriate financial aid for it. There was no agreement in understanding of which topics should be dealt with by doctors and what hierarchy of them should be used.

[Incidence of neoplasms of the hematopoietic and lymphoreticular systems in the Lower Silesia. III. Neoplasms of the lymphoreticular system in various provinces].

The incidence of lymphomas (Hodgkin's disease, non-Hodgkin lymphoma), chronic lymphatic leukaemia was compared in four provinces in Lower Silesia. The highest incidence was in the Province of Wrocław, followed in decreasing order by Legnica, Wałbrzych and Jelenia Góra. The mean annual crude index of the incidence of these diseases was in these provinces respectively: Hodgkin's disease: 2.

[Incidence of neoplasms of the hematopoietic and lymphoreticular systems in Lower Silesia. II. Incidence of leukemia in various provinces].

The incidence of leukaemia was compared in various provinces of Lower Silesia in the years 1972-1985. The highest incidence was in the Province of Wrocław and the Province of Jelenia Góra, in the Province of Legnica it was lower and the lowest was found in the Province of Wałbrzych. A similar sequence of the incidence was found when the analysis was carried out in groups of sex and place of residence (villages and towns).

[Incidence of neoplasms of the hematologic and lymphoreticular systems in Lower Silesia 1972-1985. I. Incidence in the entire region].

On the basis of data obtained from hospitals and outpatient clinics in Lower Silesia the incidence of haematological malignancies was analysed in the years 1972-1985. Totally 3739 cases were notified, mainly in urban populations. The mean annual index of incidence of leukaemias and lymphoproliferative disorders was in men 4.

Synthetic factor for evaluation of the effectiveness of the therapy in ovarian carcinoma.

The synthetic factor based on determinations of 10 parameters in sera of patients with ovarian carcinoma, was constructed. The factor was found to be useful in evaluation of the effectiveness of the cytotoxic treatment and in indication of the recurrence of the malignancy. Reduction of the number of biochemical markers to five (haptoglobin, seromucoid, lactate dehydrogenase, alkaline phosphatase, aspartate aminotransferase), according to significance of particular markers in the laboratory diagnostics of ovarian cancer did not affect the diagnostic sensitivity of the synthetic factor.

Econometric analysis of phase duration for blood morphology and basophil count alterations in chronic granulocytic leukaemia.

The retrospective analysis of 40 cases with chronic granulocytic leukemia revealed an average survival time of 39 months. Modal proportions between the chronic, accelerated and acute blastic crisis amounted to 25:6:8 months. The characteristic points and curves for peripheral white cell, blast cell, basophil cell and thrombocyte counts as well as haemoglobin levels were determined separately in 20 patients with long and in 20 with short survival time.

Maximum volumes in excised human lungs: effects of age, emphysema, and formalin inflation.

The volume of air at a transpulmonary pressure (PL) of 25 cmH2O was measured in 28 emphysema-free and 39 emphysematous excised adult lungs and in the lungs of 53 infants and children. In the adult emphysema-free lungs, this volume (V25) was significantly correlated with body length in males but, corrected for body length, not significantly correlated with age in either males or females. V25 was on the average 20 per cent larger than predicted TLC in non-emphysematous lungs in vivo.
