RESUMEN
Among 133 chemical laundries workers and 107 persons from a control group internal medical examinations together with electrocardiography record and laboratory investigation were performed. For the assessment of liver functions designations AlAT, AspAT, FA, prothrombin index, bilirubin and iron content in serum, proteinogram and thymol turbility test were prepared and carried out. No statistically remarkable differences between the group of women exposed to PER and the control group were found. In the study group of males statistically noticeable differences were related to mean values and the number of deviations connected with aminotransferases. An increased activity of these enzymes was observed in persons exposed to high instantaneous concentrations of PER. The author reflects upon the usefulness of performing biochemical investigation of the liver function during prophylactic examination of laundry workers exposed to PER.

A comparative study was carried out between the divisions of one of the viscose industry plants where workers carry on shift work in CS2 exposure and shift workers of a wool industry plant--in the same town--with no chemical exposure. It appeared that more of the CS2 exposed workers became disabled at a younger age and after shorter employment duration. As to the diseases resulting in the untimely job leave most frequent were stenocardia, accidents and tumours; on the other hand no such observations referred to diabetes mellitus and obliterative inflammation of lower extremities arteries. Chronic obturative disease nervous system diseases and hypertension, and, to a lesser degree, predominated among wool industry workers.

During 1971-1980, 128 patients were hospitalized at the Clinic of Occupational Diseases, Institute of Occupational Medicine, Lódz, for disease resulting from chronic exposure to organic solvents. The authors analyzed diseases syndromes, exposure duration prior to the disease occurrence, and professions and workplaces constituting sources of exposure to solvents. Most significant in occupational health were found to be: benzene and its homologues, chlorinated hydrocarbons and naphtha. However, exposure to solvents occurs not only in industry but also in small service and cottage--work workshops, which fairly hampers preventive measures.

In a group of 1887 men exposed to CS2 and in a 522--persons--control group haemoglobin concentration, hematocrit, average haemoglobin concentration, leukocytes number and leukogram were determined. The statistical evaluation of the distribution of the values in both populations showed no statistically significant differences.

The authors present results of studies of granulocyte marrow reserve stimulated by prednison in 60 patients exposed to physical and chemical agents damaging the hematopoietic system and compare the results with those from examinations of a 10-persons control group. The response of the granulocyte system to the stimulus is confronted with the number of leukocytes and neutrophils of peripheral blood prior to stimulation, and with the myelogram. The authors indicate that the examination of granulocytes marrow reserve by the prednison as a stimulator may be used as one of the methods allowing for evaluating the degree of exogenous lesion of the hematopoietic system.
