Endotoxins of gram-negative bacteria and of intestinal origin, insufficiently cleared by the hepatic reticulo-endothelial system are of an increasing interest within the pathogenesis of liver diseases. With purpose to obtain data concerning incidence and course of endotoxaemia in patients with liver cirrhosis an unselected group of these patients, sequentially admitted, was investigated by means of the Limulus-gelation test, regarded as most sensitive to endotoxins. At the admittance, 65% of the patients had endotoxaemia, further 14% developed endotoxaemia later. In total 79% of the patients investigated had endotoxaemia.---Bleeding from oesophageal varices was associated with endotoxaemia in 78%, functional renal impairment in 75%, consumption coagulopathy in 81%, encephalopathy in 77% and a pyrogen reaction in 82% of the patients. Regarding the Limulus assay, the dilution technique was more sensitive in detection of free endotoxaemia as opposed to the chloroform extract. It is concluded from the results that endotoxaemia in patients with liver cirrhosis is frequent and has to be viewed as relevant within the pathogeneses of chronic liver diseases.

New process, instantaneous controlled pressure drop (DIC) was applied on Cananga odorata dry flowers with the aim to isolate essential oil. DIC is based on high temperature, short time heating followed by an abrupt pressure drop into a vacuum. A part of volatile compounds is carried away from flowers in the form of vapor (DIC direct oil) that evolves adiabatically during the pressure drop (proper isolation process) and the other part remains in the DIC-treated flowers (DIC residual oil). In the present paper, the effect of DIC cycle number (1-9) and heating time (4.3-15.7 min) on the availability of oil compounds was investigated at three levels of steam pressure (0.28, 0.4 and 0.6 MPa). The availability was defined as the amount of a compound in direct or residual oil divided by the amount of this compound in the reference oil extracted from non-treated flowers by chloroform during 2h. The total availability and yield of volatiles in the direct oil increased with pressure and cycle number. At a higher pressure, the effect of heating time was insignificant. The amount of oxygenated monoterpenes and other light oxygenated compounds (i.e. predominantly exogenous compounds) in the residual flowers was lower than in the direct oil and this amount decreased with cycle number. On the other hand, the availability of oxygenated sesquiterpenes and other heavy oxygenated compounds (i.e. predominantly endogenous compounds) in residual flowers exhibited a maximum for about five cycles and their quantity at this point was three times as much as in the direct oil. The total availability of each compound at 0.6 MPa was higher than one. The rapid DIC process (0.6 MPa, 8 cycles, 6 min) gave better results than steam distillation (16 h) concerning direct oil yield (2.8%dm versus 2.5%dm) and content of oxygenated compounds (72.5% versus 61.7%).
