Distribution of a single oral dose of methyl mercury (10 mg Hg/kg body weight) was followed from 90 min up to 120 h in plasma, erythrocytes, and brain of Japanese quails and rats. Significantly higher Hg concentrations were observed in plasma and brain of quails and red blood cells of rats. Blood/brain ratio decreased in quails from 6 to 2 at 24 h and 120 h(More)
The haemorrhagic effect of unfractionated heparin and of the low molecular weight heparin, enoxaparin, on gastric mucosal bleeding induced by acetylsalicylic acid (ASA) and on skin bleeding induced by the Simplate technique was investigated in healthy human volunteers. Endoscopic estimation of gastric bleeding by visual analogue scores was more sensitive(More)
IceCube is a one-gigaton instrument located at the geographic South Pole, designed to detect cosmic neutrinos, identify the particle nature of dark matter, and study high-energy neutrinos themselves. Simulation of the IceCube detector and processing of data require a significant amount of computational resources. This paper presents the first detailed(More)
Eosinophil cationic protein (ECP) is a cytotoxic substance released by eosinophilic granulocytes. Serum and body-fluid levels may be elevated in some allergic and inflammatory conditions characterized by heavy infiltration of eosinophils. ECP has not previously been measured in feces. Because pronounced infiltration with eosinophils is often seen in(More)
The haemorrhagic effects of unfractionated heparin (UFH) and the low molecular weight heparin (LMWH) enoxaparin were investigated and compared in the gastric mucosa (haemorrhage induced by biopsy) and skin (haemorrhage induced by Simplate) of 12 healthy volunteers. Administration of UFH and LMWH (given in a dose of 75 anti-Xa U/kg intravenously) increased(More)
Studies into quantitative behaviours of oestradiol and progesterone in the blood plasma of six heads of prepuberal cattle, following superovulation treatment, using pregnant-mare serum gonadotropin (PMSG) and human chorionic gonadotropin (HCG) have shown the oestradiol concentrations to double, as early as two days after PMSG, and to go up to ten times(More)
Accordingly to the subacute toxicity of chlorphacinone to Japanese quail (LC 50: 60 mg/kg feed), the uptake of Delicia-chlorphacinone-baits for several days can be lethal to birds as a matter of principle. A subchronic study resulted in a "no-observed-effect-level" of 1 mg chlorphacinon/kg feed. Reproduction is not affected until dose levels which resulted(More)
