[Gastric necrosis caused by incarceration in hiatal hernia]. / Martwica zoladka w wyniku uwiezniecia przepukliny rozworu przelykowego przepony.

The described case illustrates the diagnostic difficulties in incarceration of abdominal organs in diaphragmatic hiatus hernia. The absence of characteristic symptoms and sudden deterioration of the general condition are causes of delay in surgical intervention leading, sometimes, to extensive necrosis of organs. The reported patient had extensive necrosis of gastric wall due to its incarceration in diaphragmatic hiatus hernia.

[Evaluation of the effect of ligation of the inferior thyroid arteries during non-radical thyroidectomy in simple goiter on selected parameters of calcium-phosphate metabolism in the body]. / Ocena wplywu podwiazania tetnic tarczowych dolnych podcazas niedoszczetnego wyciecia tarczycy z powodu wola prostego na wybrane parametry gospodarki wapniowo-fosforanowej ustroju.

The aim of the paper was to evaluate the effect of inferior thyroid arteries ligation during the incomplete excision of the thyroid gland in patients with simple goitre, exerted on selected parameters of phosphate-calcium balance in the organism as compared with a group of patients, in whom no inferior thyroid arteries were ligated. The study material comprised 84 patients with simple goitre, free of other diseases. The evaluation covered the following parameters of the phosphate-calcium balance in the organism, namely: the concentration of total calcium, protein, dialyzing calcium, inorganic phosphate as well as immunoreactive parathyroid hormone. The study was performed three times: prior to operative procedure, directly after the operative procedure, and three months after the procedure. It has been shown that there are slight, but statistically significant, differences in the behaviour involving the concentration of total and dialyzing calcium as well as IRPTH in serum, depending on the applied operative technique. Directly after the procedure the changes affecting the studied parameters were more pronounced in patients with ligated inferior thyroid arteries. Three months after the operative procedure the mean concentration of IRPTH, total and dialyzing calcium was somewhat higher in patients, whose inferior thyroid arteries were ligated, than in patients, in whom the arteries were not ligated. The described changes were of subclinical character.

[Protoporphyrin level in erythrocytes of workers in coke-producing plants]. / Zawartosc protoporfiryny w krwinkach czerwonych pracowników zakladów koksochemicznych.

Peripheral blood samples from workers of a coke factory were examined to determine protoporphyrin content in erythrocytes and haemoglobin concentration. Statistically significant increase of protoporphyrin level was found in the coke factory workers, as compared with the control group whereas haemoglobin content was very similar in both the groups. The results indicate that the working environment of coke factory may induce protoporphyrin synthesis in erythrocytes as well as inhibit generation of iron porphyrins.

[Acid phosphatase and non-specific esterase activities in peripheral blood lymphocytes of coke plant workers]. / Aktywnosc fosfatazy kwasnej i esterazy nieswoistej w limfocytach krwi obwodowej pracowników koksowni.

In 32 workers of coking plants cytoenzymatic reaction was examined in lymphocytes peripheral blood to determine the presence of acid phosphatase and unspecific esterase expressed in total score values. Statistically significant decrease of unspecific esterase activity and lower mean values of acid phosphatase activity were found as compared to the results obtained in the control group. It seems that periodical determinations of cytoenzymatic activity of unspecific esterase in lymphocytes of peripheral blood may be useful in assessment of biological effects of occupational exposure in coking plants workers.

[Neutrophil function in the peripheral blood of workers in a coke plant]. / Czynnosc granulocytów obojetnochlonnych krwi obwodowej pracowników koksowni.

In workers of the cooking plant the resting metabolism of peripheral blood neutrophils has been evaluated. The nitrotetrazolium blue reduction has been used for evaluation of above phenomenon. Simultaneously analogous investigations have been performed in properly selected control group. It has been stated that the cooking plant environment represents a strong stimulator of the neutrophil resting metabolism as seen by significant increase of the formazan-positive cells when compared with that in the control group.

[Cytochemical analysis of selected enzymes in granulocytes from the peripheral blood of coke plant employees]. / Badanie cytochemiczne niektórych enzymów w granulocytach obojetnochlonnych krwi obwodowej pracowników zakladów koksochemicznych.

Cytochemical reactions detecting catalase and myeloperoxidase in the peripheral blood neutrophils were carried out in coke plants employees. Intensity of the cytochemical reactions were expressed as total score and compared with the values obtained in corresponding control group. An increase in both enzymes activity, especially catalase, was seen. It is assumed that the in enzymatic activity may be related to iron-porphyrins being prosthetic group of these enzymes.

[Various non-specific immunity proteins in the blood serum of workers in the coke-processing industry]. / Niektóre bialka odpornosci nieswoistej w surowicy krwi u pracowników koksowni.

The concentrations of certain proteins related to non-specific immunity were determined in the serum of cokery workers and in a matched control group. No changes were found in the concentrations of the main proteins of the properdin system, that is properdin and third fraction of complement. However, the level of transferrin was higher in cokery workers. It seems that the harmful effects of the working environment were not changing the function of the properdin system. Raised transferrin level seems to be only a biochemical trace of exposure without essential importance.
