[Comparative analysis of the effects of alcoholic drinks of different qualities (author's transl)]

The authors compared the effects of alcoholic drinks rich in fusel oil with the effects of diluted pure alcohol of the same quantity on 19 clinically healthy university students. The investigations utilized EEG and physiopsychic testing methods. The clinical symptoms were observed both under the effect of drinks and in a crapulous state ("hang-over"). It was found that alcoholic drinks rich in fusel oil can produce a more deviating EEG curve, an increased worsening of physiopsychic performance and of clinical and subjective symptoms. The necessity of regular quality control of alcoholic beverages is pointed out.

Interrelationships between the gastric secretory responses, prostaglandin E2 inhibition and serum level of immunoreactive gastrin in pylorus-ligated and antrectomized rats

The effects of prostaglandin E2 (PGE2) have been studied on the gastric secretion and the serum level of immunoreactive gastrin in pylorus-ligated and antrectomized rats. It has been observed that: (1) a significant inhibition of gastric secretion (volume and acid output) was caused by PGE2, applied in doses of 75, 150 and 300 microgram/kg body weight, subcutaneously, in both pylorus-occluded and antrectomized rats: PGE2 inhibition of gastric secretion was more pronounced in rats with antrectomy; (2) no significant changes were found in the serum gastrin levels of both pylorus-ligated and antrectomized rats, and (3) no significant changes in serum levels of immunoreactive gastrin were produced by different doses of PGE2, in comparison with their marked inhibitory effects on gastric H+ secretion. It was concluded that there is no essential role of the immunoreactive gastrin, originated from the antral part of the stomach, neither in development of gastric hypersecretion nor in PGE2-produced inhibition on gastric secretion of the pylorus-occluded rats.

[Lead content of Hungarian wines (author's transl)]

The authors have investigated the lead content of 560 hungarian wines produced between 1969 and 1973 by atomic absorption spectrophotometry (Type of instrument: UNICAM SP 1900). The preparation of samples was made by wet digestion with HNO3-H202. For 94.12% of the investigated wines less than 0.4 ppm lead content was established. The 2.67% of wines contain 0.4-0.6 ppm lead. In case of 18 samples (3.21%) more than 0.6 ppm lead content was found.

[Comparative study of spirographic values and scintigraphic aspects in patients with bronchopulmonary diseases]

A correlation was made of routine spyrographic data with the scintigraphic aspects of the lungs in 146, respectively 100 patients with bronchopulmonary diseases. The following conclusions can be inferred: 1) normal spirographic values do not necessarily reflect an integrity of the respiratory function. Besides these values pulmonary perfusion can be severily altered; 2) the more deteriorated the spirographic values the more probable will be the alteration of the pulmonary perfusion; 3) in the evaluation of the respiratory function one cannot base on the routine spirographic data if these are within normal limits, especially before pulmonary surgery is performed, or before the patients are resuming active life; according to possibilities, the scintigraphic investigation is to be performed.
