Response of the solid Guerin epitheliomas of rats to fractionated irradiation and a new 4-nitroimidazole.

The transplantable Guerin epithelioma in Wistar rats was used to test the in vivo effectiveness of 1-(2-hydroxy-3-methoxypropyl)-2-methyl-4-nitroimidazole (P1) as a tumour-cell radiosensitizer after its oral administration at relatively low doses. The radiosensitizing ability of P1 was compared with that of metronidazole. The results indicate that P1 is less toxic than metronidazole, and greater concentrations of P1 in blood and tumour tissues are obtained for the same administered dose of the compounds. The radiosensitizing ability of P1, determined from tumour-regression rates and local-control percentage at 130 days, was higher than that of metronidazole.

[Activation level and the mechanism of emotional control in patients with paranoid schizophrenia].

The group of 60 paranoid schizophrenics and pair-matched group of 60 healthy controls were studied. The level of activation was measured by LPT technique by R. E. Thayer, and J. Brzezinski's Questionnaire for Emotional Control was used. The results indicate no differences between the level of activation among paranoid schizophrenics and controls. Patients, in comparison to healthy subjects, showed low level of emotional control, undeveloped control of emotional expression, impulsiveness, the high threshold of emotional arousal, the lack of resistance to emotions, and low level of control of behaviour in emotional states.
