Viral infection and exposure to hypoxia led to a significant increase in ppET mRNA compared with all other groups Fig. 1, ANOVA P 0.04; multiple-comparison posttesting, hypoxia virus P 0.03 vs. all other groups ; . Hypoxia following viral infection increases lung VEGF expression. As we have previously reported in a different animal model that elevated lung ET levels can promote increases in lung VEGF content 4 ; , we sought to determine whether the combination of recent viral infection and exposure to moderate hypoxia results in elevated lung VEGF content. The VEGF protein content of lung homogenates from animals in our four experimental groups was measured by Western blotting Fig. 2 ; . Although viral infection alone did not change lung VEGF expression and exposure to hypoxia alone led to a modest, statistically insignificant increase in VEGF expression, exposure to the combination of viral infection and hypoxia led to a significant increase in lung VEGF content ANOVA P 0.004; posttest, P 0.05 hypoxia virus vs. all other groups ; . To determine whether the increase in lung VEGF protein content seen with the combination of viral infection and hypoxia was due to increased transcription of VEGF mRNA, we assessed expression of VEGF mRNA by relative RT-PCR using primers that amplified four alternatively transcribed VEGF transcripts: VEGF189, VEGF165, VEGF144, and VEGF121. Consistent with the results of the Western blotting studies, we found a significant increase in lung VEGF mRNA expression in the hypoxic infected animals compared with all three other groups ANOVA P 0.007; posttest, P 0.05 hypoxia virus vs. all others; Fig. 3 ; . The detectable increase in VEGF mRNA expression was limited to the VEGF189 transcript. No differences were found in the expression of other VEGF mRNAs between the four experimental groups. To determine which cells in the lung accounted for the increase in lung VEGF content detected in the hypoxic infected animals, we performed immunohistochemical studies of VEGF expression in zinc formalin-fixed paraffin-embedded sections.

Release rate by varying the current density data not shown ; . Comparing the release rate values of metoprolol Table 5 ; to the release rate of tacrine Table 1 ; at the same salt concentration and current density shows that the release rates of metoprolol were an order of magnitude greater than the corresponding release rates of tacrine. The differences between the release rates did, however, decrease when the current density was increased. Our earlier studies already established that metoprolol is released from the fibers substantially faster than tacrine [14] and that the release of tacrine from several types of ion-exchange fiber is slower compared to other drugs [11]. It was suggested that the differences in the release rates could be due to the lipophilicity of the drug; lipophilic drugs were more strongly bound to the fibers than hydrophilic drugs [11 13]. This appears to be the case in the present work, as the logP for tacrine is 3.3 and for metoprolol 1.88 [18]. Additionally, it was established that tacrine adsorbed on to the electrode surfaces Table 4 ; , which was not detected in the case of metoprolol.
Cells exert traction forces onto the extracellular matrix ECM ; , changing both the density and the orientation distribution of ECM fibers. ECM strain, in turn, affects cell migration. We study the effect of mechanical cell-ECM interactions on cell migration and cell distribution assuming a continuum description for the cells and the ECM. The theory assumes that the ECM is a viscoelastic material which deforms under cellular traction, and that resulting ECM strain influences cell movement. Numerical simulations predict that under certain mechanical conditions, cell traction can reorganize the cells and associated ECM into a network that compares well with the vascular networks that arise in vitro. I discuss the potential role of cell mechanical forces and ECM mechanical behavior on cell migration, and compare results with in vitro studies.

Fig. 2, however, demonstrates that CPT-11 does inhibit the catalysis of 3 mM o-NPA and 4 mM PTC by AcChE. Fifty % inhibition of o-NPA metabolism was observed with 0.31 and 0.14 M CPT-11 for the human and eel AcChE, respectively. With PTC as a substrate, 50% enzyme inhibition was seen with 1.3 and 2.0 M CPT-11 for the human and eel AcChEs, respectively. Because these concentrations of CPT-11 are readily achievable in the plasma of patients undergoing chemotherapy 3 ; , we determined the Kis of CPT-11 for the human and eel AcChE using the surrogate AcChE substrate, acetylthiocholine. Table 1 indicates the apparent Kis for CPT-11 with purified amphiphilic human and eel AcChE. The two enzymes had similar Kis in the nanomolar range Table 1 ; . Because CPT-11 is metabolized to both APC and SN-38 in patients, we also assessed the inhibition of AcChE activity by these two compounds. Although both metabolites could inhibit the metabolism of acetylthiocholine by AcChE, the Kis were 70 95-fold greater than that for CPT-11 Table 1 ; . Because these concentrations have not been reported in patient plasma, it is likely that CPT-11 is responsible for AcChE inhibition in vivo. CPT-11 Is a Substrate for BuChE. Similar to the above studies with AcChEs, we also examined the ability of BuChEs to convert CPT-11 to SN-38. We incubated 25 M CPT-11 with 800, 80, or 8 units of equine BuChE for 22 h at 37C in 50 mM Hepes pH 7.4 ; and analyzed the reaction products by HPLC. We detected SN-38 with as little as 8 units of BuChE Fig. 3A ; . With 800 units of enzyme, 98% of the CPT-11 was converted to SN-38. Similarly, with 5 units of human BuChE, drug activation was observed; however, the reactions were less efficient than those with the equine protein. Kinetics of CPT-11 Conversion by BuChEs. To compare the efficiency of CPT-11 catalysis by human and horse BuChEs, we incubated each enzyme with concentrations of drug, ranging from 0.1 to 125 M. For the equine enzyme, 100 units were used, and reactions were allowed to proceed for 5 min at 37C. For reactions with the human BuChE, 5 units of enzyme were incubated with substrate overnight at 37C. Table 2 indicates that, although similar Kms were observed for each enzyme, the human BuChE is 250-fold less efficient than the equine protein at drug activation, as indicated by the Vmaxs. Inhibition of BuChE-mediated CPT-11 Metabolism by Tacrine. Tacrine specifically inhibits cholinesterases because it forms a covalent bond with the active site serine residue. This reagent, therefore, should prevent activation of CPT-11 by BuChEs. Therefore, we incubated 10 units of equine BuChE with 25 M CPT-11 in the presence of 1 mM tacrine. After incubation at 37C for 22 h, 99% inhibition of the conversion of CPT-11 to SN-38 was observed Fig. 4B ; . These data support the conclusion that BuChEs metabolize CPT-11. Activation of CPT-11 by Esterases in Mouse Plasma. CPT-11 is converted to SN-38 by mouse plasma. However, because both carboxylesterases and cholinesterases are present in plasma, the relative contribution of each enzyme to drug activation is unknown. To assess the contribution of each enzyme, we incubated 5 M CPT-11 with 50 and tarceva.

Benzodiazepines, where active metabolites have been demonstrated to contribute significantly to the effect Crevoisier et al., 1983; Garzone and Kroboth, 1989; Mandema et al., 1992b ; . When a drug is converted into an active metabolite, generally the situation arises where two active species are present which, as result of their close structural similarity, compete for the same receptor. Therefore, typically a competitive interaction model is required to characterize the combined effect of a drug and its active metabolite. Recently the modeling of the pharmacodynamic interactions between benzodiazepines has been the subject of a number of investigations. Specifically, empirical interaction models have been proposed to characterize the interactions between a benzodiazepine full agonist on one hand and benzodiazepine partial, competitive, or inverse ant ; agonists on the other Mandema et al., 1992a, c ; . So far, however, the modeling of the pharmacodynamic interactions between two full agonists or between parent drug and its active metabolite ; has not been reported. In this paper a new mechanism-based model is proposed and tacrine.

Erythromycin: This is the treatment of choice for Legionella, Campylobacter, and Mycoplasma pneumoniae infections and for the treatment and prevention of whooping cough. It is used to treat chlamydial and ureaplasma infections in pregnancy or childhood, when tetracycline is contraindi-cated. Erythromycin has only marginal activity against Haemophilus influenzae. It is a useful drug in the treatment of infections caused by Streptococcus pyogenes and pneumococci in patients allergic to penicillin. Roxithromycin has similar antibacterial activity to erythromycin but has a longer half-life and has improved activity against Haemophilus influenzae. It is given twice a day. Clarithromycin has significantly increased activity against organisms traditionally considered susceptible to erythromycin, plus good activity against Mycobacterium avium and Helicobacter pylori. The major advantage over erythromycin includes better gastrointestinal absorption and tolerance and activity against Haemophilus influenzae. It is given once or twice twice a day. Azithromycin is less active than erythromycin against staphylococci and streptococci but more active against Haemophilus influenzae. It has a long half-life, allowing once daily dosing.
