nolol is essentially complete, and no metabolism of this drug occurs in the gut. After the oral administration of propranolol, the liver is the principal site of extensive pre-systemic and systemic metabolism, and less than 1% of the intact drug is found in the urine. However, Bianchetti et al. showed that the area under the concentration–time curve for orally administered propranolol in renal ...

The present study was conducted to investigate the effects of boldenone undecylenate (BUL) on carcass traits and blood stress parameters in growing male rabbits. A total of 170 male rabbits comprising of three breeds namely New Zealand White (NZW; n=55), Californian (CAL; n=50), and Rex (RX; n=65) were taken for this study. The rabbits of each breed were divided into three groups viz., D0 (cont...

To investigate the mechanism responsible for the increased bioavailability of propranolol in bilateral ureter-ligated (BUL) rats, the intestinal absorption and hepatic extraction of propranolol and metoprolol were evaluated. The initial absorption rate of these drugs after intra-intestinal administration was only slightly increased in the BUL rats, whereas the blood drug concentration in these ...

A new galactose-binding lectin, termed BUL, has been purified from seeds of Bauhinia ungulata (Caesalpinoideae) by precipitation with solid ammonium sulfate followed by agarose-lactose affinity chromatography. B. ungulata lectin strongly agglutinated rabbit erythrocytes, both native and treated with proteolytic enzymes, and was inhibited by D-galactose and D-galactosederived sugars, especially ...

Like other Nedd4 ligases, Saccharomyces cerevisiae E3 Rsp5p utilizes adaptor proteins to interact with some substrates. Previous studies have indentified Bul1p and Bul2p as adaptor proteins that facilitate the ligase-substrate interaction. Here, we show the identification of a third member of the Bul family, Bul3p, the product of two adjacent open reading frames separated by a stop codon that u...
