[The determination of Cu, Cd, Pb, Co and Ni in material with the use of the ICB-AES method]. / Oznaczanie sladowych ilosci Cu, Cd, Pb, Co i Ni w materiale roslinnym technika ICP-AES.

The purpose of the study was utilization of emission atomic absorption spectrometry with excitation in induction-coupled plasma for determination of Cu(II), Pb(II), Cd(II), Co(II) i Ni(II) in plant material. The possibility of using inorganic carrier for separation of trace amounts of heavy metals from aqueous solution is presented. Optimal conditions for coprecipitation of metal ions with Mg(OH)2 as well as for their determination by means of the ICP-AES method are described. The conditions of heavy metals separation and concentration make possible determination of the metals in the concentration from 0.01 to 0.20 microgram/ml by the ICP-AES. As a result simple method was elaborated for group concentration and determination of the above mentioned metals in samples of plant material. The studied food products were mineralized with concentrated HNO3, HClO4 and perhydrol. The method of preconcentration and determination was used for metals determination in dairy products in concentrations about 5 x 10(-5)%. As a result simple and economical method was elaborated for group preconcentration and determination of the above mentioned metals in samples of plant material.

[Restenosis after percutaneous coronary angioplasty--cause, prevention strategies]. / Restenoza po przezskórnej angioplastyce wiencowej--mechanizm powstawania, próby zapobiegania.

PTCA is a new method of invasive cardiology. Restenosis is an important limitation of efficacy of this method. It occurs in 20-45% of patients. Pathomechanism of the restenosis is not clear. It is assumed, that restenosis is an answer of the endothelium to the procedure. This response consists of the inflammation, platelet primary adhesion and aggregation, proliferation of smooth muscle cells and intercellular matrix production. These changes together with old atheroma and thrombus create a new stenosis. There were many attempts to prevent restenosis based on the pathophysiology, but so far no successful method has been found.

[Determination of lead (II) in food using the ICP-AES method after condensation on the lanthanum carrier]. / Oznaczanie olowiu (II) w zywnosci metoda ICP--AES po zageszczeniu na nosniku lantanowym.

The purpose of the study was utilization of emission atomic absorption spectrometry with excitation in induction-coupled plasma, and molecular spectrometry for determination of lead in milk and dairy products after condensation in ammonia atmosphere. Two methods were proposed for lead condensation on lanthanum carrier--in form of hydroxide or sulphide. By coprecipitation of lead on lanthanum in ammonia atmosphere lead separated and selectively condensed. Other metals (Zn, Cd, Cu) coexistent in food products remained as amino complexes in the solution. The sediment remaining after lead condensation was dissolved in 2 mol/dm3 hydrochloric acid solution. The selected conditions of lead separation and condensation make possible determination of the metal in the concentrations from 0.01 mcg/ml to 0.2 mcg/ml by the ICP-ARS and dithizone methods. The method of condensation and determination was used for lead determination in milk and dairy products in concentrations below 1.5 x 10(-5)%. The studied food products were mineralized with concentrated HNO3, H2SO4 and perhydrol. This mineralization method makes it possible to determine in one mineralisate directly copper and zinc by ICP-ARS and dithizone methods, and lead after condensation. The obtained results were precise and reproducible.

[Treatment of recent myocardial infarction during menstruation--presentation of a case]. / Leczenie fibrynolityczne swiezego zawalu serca w czasie menstruacji--opis przypadku.

A young woman was admitted because of recent myocardial infarction (MI). Although she displayed menstruation bleeding, thrombolytic therapy with tpA was instituted. This resulted in full reperfusion and uneventful clinical course of MI. There was no prolongation of menstruation. Fibrinolytic treatment in women with MI and menstruation seems to be a safe procedure.

[Evolution of diastolic polycardiographic indicators in hypertrophic cardiomyopathy]. / Ewolucja rozkurczowych wskazników polikardiograficznych w kardiomiopatii przerostowej.

In a group 26 patients with hypertrophic cardiomyopathy the values of certain polycardiographic and haemodynamic indices and their changes in the prolongation of the time of isovolumetric relaxation (IVRT) was noted in 23 patients (88%), with increased value of the percent of the a wave participation of the apexcardiogram (%a) in 24 patients (92%). In the obstructive type the corrected time of left ventricular ejection was significantly prolonged (p < 0.01) in relation to the non-obstructive type. No difference was observed in the values of these parameters depending on the functional class. A weak but significant correlation was demonstrated between the %a and the end-diastolic left ventricular pressure (r = 0.579, p < 0.01). The IVRT value showed an increasing tendency in this prospective study, particularly in patients with progression of clinical symptoms.
