Summary: To replace J131-HSA as a marker of plasma volume with
Tc99m-HSAwe assesed blood volume on a group of 23 healthy female
subjectsaged between 20 to 40. The good correlation between two methodswas
established (r=0.961; 10 minutes values). The escape factorfor J131-HSA and
Tc99m-HSA was assessed (10 minutes 1.015ń0.0064and 20 minutes 1.254ń0.0895,
respectively). The representativeblood sample for Tc99m-HSA is in 20th
minute and for J131-HSA in10th minute. We concluded that method with
Tc99m-HSA is reliableand reproducible.

Summary: The aim of our prospective study is the functional
examination ofthe cardiovascular (CV) system in hemodialysed patients
beforeand after anemia correction by Erithropoietin (Epo). We
usedechocardiographic studies and radionuclide ventriculography atrest and
during exercise. After correction of anemia thesignificant decrease apeared
of the initially high cardiac output(CO) and cardiac index (CI) from
7.55ń3.15 to 6.3ń1.8 and from4.2ń1.7 to 3.6ń1.0. Initially raised
peripheral resistence index(TPRI) of 2582.3ń2097.3 dyn/sec/mý has not
changed significantlyas well as the mean diastolic (DBP) and the mean blood
pressure(MBP). There appeared the significant decrease of
endodiastolic(EDV), endosystolic (ESV) volume (p<0.005) and of CO
(p<0.005).The desrease (n.s) of the mean values of the LVM was
significantfor the subgroup of the patients with the initially greather
LVM.The ejection (EF) remained unchanged (73.9%). The functionalcapacity of
the CV system was increased from 4 metabolicequivalent (MET) (V O2 max.
14.0 ml/min/kg) to 6 MET (V O2 max.20) (p<0.001). The blood volume has not
significantly changed. Weare concluding that the hemodynamic effects of the
anemiacorrection are favourable. The caution is necessary in followingthe
patients with initially lower values of the LVM. The changesof blood
volume, blood presure, the rapidity of rise and thetarget values of Hgb and
Htc should be individually monmitored toavoid pressure or volume overload
of the heart. The defineconclusion on the satisfying effects of the therapy
with Epo onthe CV morbidity and mortality should be postponed for the
largerprospective studies.

Summary: In 19 hemodialysis patients with severe renal anemia
(meanhemoglobin (Hg) 73q6 g/l) left ventrikular function was
investigated with radionuclide ventriculography at rest and
during exercise twice: a) before recombinant human
erythropoiethin therapy (rHuEPO Th) and b) after 3.4q1.4 months
when target Hb reached 100 g/l. After treatment significant
reduction in cardiac index (CI) at rest (4.99 before vs. 3.81
l/min/mć after, p<0.01), and exercise (7.89 before vs. 6.49
l/min/mć after, p<0.01) was found. The fall in CI was due to
reduction in EDV after rHuEPO Th (p<0.05) at rest and exercise
and reduction of HR at rest (p<0.05). EF, ESV, blood volume and
BP remained unchanged after rHuEPO Th. While PER and PFR did not
changed, TPFR was significantly prolonged after Th at rest and
exercise (p<0.05). The patients showed a significant rise in
thair maximal work load (52%) and exercise duration (53%) after
Th, although changes in maximal HR and BP did not achieved
statistical significance under Th. No significant correlation was
found between the duration of hemodialysis, increase in Hb and
improvement in cardiac function and exercise capacity. We
conclude that correction of anemia by rHuEPO improved cardiac
function and increase exercise capacity in hemodialysis patients.

Summary: In this investigation involved some cardiac and
non-cfardiacparameters at rest and after exercise in a selected group of
35women patients whose age varied from 20 to 40 years and whosuffered from
the floride Grave's disease. The control exemines(N=35) corresponded with
the diseased group in age and sex. Whileat rest the hyperthyroid group
shows no significant increase ofCO with unchanged SV which indicates that
the increased CO is tothe largest extent the result of the increased HR.
This can beexplain by the increased sympatic stimulation. The
increasedsympatic stimulation also leads to the increased PRA. Also the
EFis increased as results of the increased contractility inhyperthyroid
group. The exercise was done by means of bikeergometer in duration of 10
minutes with the intensity od 50 to75 W in the supine position. ERPF value
in the hyperthyroid groupwas higher than it was with the control group (but
its ratio doesnot increase in relation to the total CO). It showed
nosignificant changes after the exercise in both tested groups.Both groups
showed an increase in EF, HR and CO after exercise,but all these parameters
were even more pronounced in the controlgroup. The healthy group had also a
significant increase in SV.The PRA in the hyperthyroid group was higher in
rest with atendency of increasing in exercise. The application of the
betaadrenergic blocators reduces significantly the PRA both in restand in
exercise. This makes us conclude that the increased valueof the PRA is the
effect of the increased activity of thesympathic system in hyperthyroidism.
The systolic blood pressure,the pulse pressure and the double product
showed significantdifferences in the both groups as regards their metabolic
statesas well as after exercise, whereas it increased significantly inthe
control group.There was no significant difference in rest inproportion of
the ERPF/MV between the observed groups, but afterexercise the difference
was significant, and it was greater incontrol group. No interdependence
was faund betweenthe PRA and the ERPF in the diseased group. The results
of theinvestigations show that some parameters of cardiovascular systemof
the diseased group had a poor reaction in rest but thay werepronounced
after exercise.
