Individual reactions and psychophysiologic reactions in patients with mild primary hypertension]

Fourteen male patients with mild hypertension, aged between 20 and 46 years (mean = 32.4 years) measured their arterial blood pressure thrice daily for 6 weeks. Prior to and after this period psychological tests were carried out, including Gough's ACL test and Spielberger's STAI questionnaire. All patients underwent also Kraeplin's test under stress conditions twice during the experiment. It was found that there is significant correlation of personality response syndromes such as: need for acceptance, inferiority complex, need for success, trust to themselves, anger and some values of blood pressure. So-called personality syndrome related to hypertension was established. Psychophysiological picture accompanying emotional stress was discussed and relationship between blood pressure values (prior to and after emotional stress) and personality syndromes were defined.     

The coexistence of chronic lymphocytic leukaemia and polycythaemia vera terminating in acute myeloid leukaemia

A 67-year-old man with the coexistence of CLL and PV converted after 4 years to AML is described. This rare simultaneous occurrence of both chronic lymphoid and myeloid proliferations as well as nonlymphoblastic leukaemia developing in a patient with CLL is discussed in the light of literature data.     

Histofluorescence studies of central monoamines. Comparison of Falck, cryostat and SPG methods.

The aim of the presented paper was to compare the Falck-Hillarp histofluoresce method for monoamines with its cryostat modification and the glyoxylic acid SPG method. The sensitivity and specificity of these methods and also the occurence of unspecific fluorescence is discussed.     

Lead uptake,localization and changes in cell ultrastructure ofFunaria hygrometrica protonemata

The main sites of lead entering the protonemata were spores with broken cell walls and apical cells of protonemata. The lead ions could enter the symplast probably by endocytosis but we can not exclude diffusion as the way of entering. Lead deposits inside a protoplast were observed after 2 h of lead application. After 12 h, Pb deposits were commonly present in all cell structures surrounded by a membrane. Some disturbances in ultrastructure of organelles were found after 8 h. The most frequent were: change of endoplasmatic reticulum configuration from linear to concentric one in many cases surrounding other organelles (e.g. mitochondria) and large and numerous plastoglobuli in chloroplasts. Longer treatment of protonemata with lead (24 h or 48 h) caused degeneration of organelles and even death of the cell. The present work was supported by a grant from the State Commitee for Scientific Research no. 1575 9101 for E.A.G.
