Glutamine and other amino acid losses during continuous venovenous hemodiafiltration.

Serum amino grams and daily losses of glutamine (Gln) and other amino acids (AAs) into diafiltrate were measured during the first 5 days of continuous venovenous hemodiafiltration (CVVHDF) in 6 ICU patients with acute renal failure (ARF). Four patients had ARF as a part of multiple organ failure (MOF) of septic origin, and 2 patients had isolated ARF because of primary renal disease. During the study, all the patients received defined total parenteral nutrition (TPN).

A clinical study to assess the effect of heparin in dialyzer rinsing solutions.

The solution usually recommended for rinsing the blood side, which is an indispensable step in preparing a dialyzer for hemodialysis (HD), contains saline and heparin. The heparin used for rinsing is said to reduce the thrombogenic properties of the dialysis membrane and, hence, also the need for systemic heparinization during the whole procedure. The aim of our study was to establish whether this postulate also applies to polysulphone steam-sterilized dialyzers.

[Adjuvant therapy of lung cancer].

The authors evaluated in a retrospective investigation the effectiveness of adjuvant postoperative chemotherapy (ChT) and radiotherapy (RT), as compared with surgery alone, according to morphological types and stages of cancer lung (CaP). In a group of 321 patients 143 were treated by operation alone, 36 by operation and RT and 53 by operation and ChT. ChT involved administration of Cyclophosphamide, 30 mg/kg, at three-week intervals, some of the patients were also given vincaalkaloids.

[Effectiveness and reliability of preoperative studies in patients with lung cancer].

The data of documentation of 267 operatively treated patients with lung cancer are shown in a retrospective study. The patients were treated in the clinic for tuberculosis and respiratory diseases of the faculty hospital Plzen. In 50% of the cases the results of histological and cytological examinations correspond with the surgical observations.
