Unusual case of granular lymphocytes (GL) proliferation: simultaneous reactive and neoplastic proliferation.

We report a case of a 55-year-old male with lymphoproliferative disease of granular lymphocytes. In the first year of follow-up reactive expansion of granular lymphocytes was observed during infectious episodes additionally to malignant proliferation. Histopathological studies revealed malignant lymphocytic infiltrations of the liver and gallbladder walls. The number of GL varied from 1.1 G/l to 17.8 G/l. Immunophenotyping studies showed surface phenotype CD3+, CD8+. There was markedly reduced NK cell function. The patient exhibited lack of severe parenchymal involvement, moderately increased white cell count (up to 21.0 G/l), severe neutropenia (0.06 G/l - 0.8 G/l) and recurrent infectious episodes.

[Lysozyme activity in the saliva of industrial workers exposed to fluorine compounds].

The authors performed investigations in Phosphoric Fertilizers Works in Gdańsk to find out whether or not the work environment contaminated by fluorine compounds affects the activity of lysozome--the protective enzyme of saliva. In some in vitro experiments lysozome activity in exposed workers' saliva was found to be significantly lowered, as opposed to that in unexposed workers. In vivo experiments did not indicate any effects of work conditions on the activity of this enzyme. The obtained results, in vivo and in vitro, do not demonstrate any clear effects of work environment in the Phosphoric Fertilizers Works in Gdańsk, upon lysozome activity in workers' saliva.

[Activity of acid phosphatase in saliva of industrial workers exposed to fluorine compounds].

Assuming that fluorine is a strong inhibitor of phosphatases, the activity of acid phosphatase in the saliva of 42 phosphorus fertilizers plant workers was studied. The workers were chronically exposed to fluorine compounds. Saliva had been collected for studies before the workers entered the productive plant and after the 1st and 2nd working hour. Enzyme activity was determined by Bessey and Lowry's method and was related to both the volume of the saliva and total protein level. The studies revealed a significant decrease in the activity of acid phosphatase after the 1st and 2nd working hour in those working in the division with a higher exposure to fluorine compounds. The results of these studies were confirmed by in vitro studies carried out additionally. Taking into account biological activity of acid phosphatase it seems that the observed phenomenon of inhibiting enzymatic activity may be connected with the frequency of parodontopathy in the studied group of workers. The results of these studies may be used for working out a biological test of workers' exposure.

Group systems of serum proteins and erythrocyte enzymes in malignant lymphoma.

Four group systems of serum proteins (Hp, Gc, Gm, Km) and five group systems of erythrocyte enzymes (AP, PGM1, GPT, AK, EsD) were determined in 63 patients with malignant lymphoma. Statistical analysis of the distribution of the above mentioned systems in patients and Polish population samples did not reveal any significant differences, which points to the lack of any correlation between the disease and the group systems under examination.

Disseminated intravascular coagulation (DIC) during superacute haemolysis in a patient with ovarian dermatoid cyst treated with rifampicin.

A 53-year-old female patient with ovarian dermatoid cyst and lung tuberculosis had been treated with rifampicin. During repeated rifampicin treatment she developed an acute haemolytic syndrome with haemorrhagic diathesis. Laboratory findings showed that it was caused by disseminated intravascular coagulation. Death ensued despite intensive administration of heparin and Trasylol. It is assumed that the repeated rifampicin application had provoked massive haemolysis by an allergic mechanism leading to thrombofibrinolytic haemorrhagic diathesis.

[A case of Osler-Rendu disease with simultaneous thrombopenia and a factor VIII inhibitor].

Long-term determinations of haemostasis factors in a case of Osler's telangiectasia revealed the temporarily simultaneous existance of periods of thrombocytopenia, a decrease of prothrombine and a reduction of the fibrinogen and plasminogen level. These findings considered as signs of consumption coagulopathy coincided with an increased bleeding tendency of the patient. The correlation existing between the clinical symptoms and the observed disorders of coagulation may possibly be explained by the appearance of an intravascular coagulation during the late period of the haemorrhagic diathesis, which could be proved by the simultaneous increase of fibrinogen degradation products. Moreover, the patient's plasma was capable of strongly inhibiting factor VIII of a normal plasma. The possible influence of plasmatic disorders of coagulation which are caused by secondary reasons on the clinical picture of a haemorrhagic diathesis primarily based on vascular conditions is discussed.
