Asphyxiophilia is a paraphilia of the sacrificial/expiatory type in which sexual arousal and the attainment of gratification depend on hypoxia induced through either strangulation, smothering, chest compression and/or the inhalation of volatile substances. A peculiar, auto-erotic variant of this
During ten-month stay at 3200 m altitude in the Tien Shan mountains a significant increase of systolic pressure and practically unchanged diastolic one in pulmonary artery were recorded in rats. A redistribution of the blood flow and volume occurred. An increased oxygen blood capacity was maintained
Experiments on narcotized cats have shown that intravenous administration of armine in DL50 (0.2 mg/kg) decreases the pulmonary blood flow by 52%. The reduction of the pulmonary blood flow is accompanied by a drop of pressure in the femoral artery, development of bronchoconstriction, bradycardia and
The influence of prolonged moderate (c. 60% oxygen saturation) and severe hypoxia (c. 35% oxygen saturation) on the diurnal activity pattern of sandeel Ammodytes tobianus was examined. In moderate hypoxia, the emerging and burying rates were significantly higher compared to that in normoxia, whereas
Pulmonary hemodynamics in anesthetized rats was studied during long-term residence (2,5 and 10 months) at high altitude (3,200 m, Tien Shan). Transbronchial regional electroplethysmography and catheterization of pulmonary artery was used. It has been shown that at all periods of adaptation there was
The hypoxic ventilatory threshold of many mammals correlates with their hemoglobin-oxygen affinity (P50). Yet, in some small mammals ventilation actually declines, rather than increases, with exposure to decreasing PaO2; their air convection requirement (V(E)/V(O2)), however, is elevated in hypoxia.
The effects of phosphine, hydrogen cyanide and anoxia on levels of ATP, pyruvate and lactate in Rhyzopertha dominica are compared. The effect of phosphine on anaerobiosis is not directly comparable either with HCN or anoxia. Reduction of catalase by feeding 3 amino 1,2,4 triazole does not enhance
Luteolin (Lu) exhibits a wide spectrum of anti-tumor activities, the present study was to observe whether Lu can sensitize breast cancer cells to doxorubicin (Dox) and to explain the basis underlying this phenomenon. In vitro, Lu at dose less than 100 microM had only slight effect on cells growth
Delayed gastric emptying of solid food is greater after proximal gastric vagotomy (PGV) than after anterior lesser curve seromyotomy with posterior truncal vagotomy (ASPTV) and may be due to the hypoxia in the gastric wall and mainly in the gastric pacemaker.
OBJECTIVE
To verify if operative
