[Experimental droperidol protection and treatment of pulmonary edema].

The authors carried out an experimental study of the protective and therapeutic effect of droperydol on 48 rabbits, with adrenaline lung edema. The results from the conducted studies showed that droperydol, administered both prophylacticaly and therapeuticaly, diminished significantly the gravity of lung edema and increased the percentage of survival up to 67.7% (in rats, treated therapeuticaly) and up to 100% (in the rats, treated prophylacticaly), while the survival did not surpass 20% in the control group. These results were better in comparison with the data, found earlier, indicating the effect of chlorasine, which manifested only protective action in rabbits with lung edema and worsened its course, when it was applied therapeuticaly.

Alteration in the uptake and storage of cardiac noradrenaline in spontaneously hypertensive rats.

Uptake and storage of noradrenaline administered to Spontaneously hypertensive rate (SHR) (14) was significantly reduced compared with normotensive Wister rats (NR). Initial uptake of noradrenaline at 10 minutes was only 19 per cent less in SHR than in NR. However, 60 minutes following the administration of noradrenaline, its concentration in the heart of SHR was 60 per cent less than that in NR. Noradrenaline administered to NR disappeared from the heart in 10 hours, and that from SHR in 5 hours only.

[Physical work capacity in soldiers after treatment and leave of absence for acute pneumonia].

The physical activity capacity (W170) was twofold determined in 26 soldiers, aged about 20 by the method of three-stage loading (25,50 and 75 W) upon mechanic veloergometer and with the aid of regression extrapolation- at the release from the hospital after treatment for acute pneumonia and after 28+/-11 days of home sick leave. W170 was established not change significantly after the sick leave in spite of the favourable evolution towards further normalization of the remaining X-ray changes of the pneumonia and RES. The possible explanations are discussed for that W170 decrease after acute pneumonias and the conclusion is that further investigators in the field are necessary.

[Obstructive changes in the lung of young smokers].

The results from the spirometric investigations of pulmonary function in comparable grpis pf 28 smokers and 37 non-smokers at the age of 20 are presented. Positive obstructive changes were established to be present in the lungs of the smokers (smoked about 20 cigarettes daily in the course of four years and more); they were varified by the essential decrease of FEO1, MRFR200-1200, MAEFR25-75, EFR25 and EFR10. MMV50 is decreased with a critical statistical significance.

[Studies of the antistreptolysin titer in patients with acute pneumonic processes].

Antistreptolysin O level in blood serum is determined in double tests in 164 patients, 116 out of them with acute pneumonic processes. Antistreptolysin titre was established to be over 300 ASE in about 1/5 of the patients with acute focal pneumonias. In 10,4 per cent of the cases with acute pneumonic processes, an ascending dynamics of antistreptolysin O titre is observed in the course of the treatment and in 2,6 per cent the titre elevation is three and fourfold. In the interpretation of the data of the antistreptolysin titres in patients with acute focal pneumonia the possibility of oculte streptoccocal infection with another localization must not be neglected as well as pathological processes in liver parenchyma, leading to non-specific titre elevation.

[Obstructive changes in the lungs of young smokers].

The results from the spirometric investigations of lung function in two comparable groups of 28 smokers and 37 non-smokers, aged at an average of 20 are presented. Positive obstructive lung alterations were established in the smokers (smoking about 20 cigarettes daily in the course of four and more years); they were confirmed by the considerable decrease of FEV1MEFR200-1200MMEFR25-75,EFR25 and EFR10. MMV50 is decreased with a limited statistical significance.
