A study of the rabbit eye test system to determine the activity of acidic non-steroidal anti-inflammatory agents

Wiseman, Ian Charles January 1977 (has links)
From introduction : "Inflammation per se, has been defined sufficiently to permit a rational approach to the search for drugs that modify this process, but satisfactory animal models for most rheumatoid diseases are not available". (Swingle 1974) In the search for new meaningful procedures for the detection and evaluation of anti-inflammatory drugs, the rabbit eye as a test system was studied.

Huprines as a new family of dual acting trypanocidal–antiplasmodial agents

Defaux, J., Sala, M., Formosa, X., Galdeano, C., Taylor, M.C., Kelly, J.M., Wright, Colin W., Camps, P., Muñoz-Torrero, D., Alobaid, Waleed A.A. January 2011 (has links)
No / A series of 19 huprines has been evaluated for their activity against cultured bloodstream forms of Trypanosoma brucei and Plasmodium falciparum. Moreover, cytotoxicity against rat myoblast L6 cells was assessed for selected huprines. All the tested huprines are moderately potent and selective trypanocidal agents, exhibiting IC50 values against T. brucei in the submicromolar to low micromolar range and selectivity indices for T. brucei over L6 cells of approximately 15, thus constituting interesting trypanocidal lead compounds. Two of these huprines were also found to be active against a chloroquine-resistant strain of P. falciparum, thus emerging as interesting trypanocidal–antiplasmodial dual acting compounds, but they exhibited little selectivity for P. falciparum over L6 cells.

Theoretical modelling of ultrasound contrast agents

Looney, Padraig January 2011 (has links)
This thesis compares theoretical models of ultrasound contrast agents to the acoustic response from single Microbubbles(MBs). The acoustic response was compared using a range of driving parameters. A rigid shelled contrast agent and a lipid shelled contrast agent were used in the comparison. While attempts to model the behaviour of some contrast agents at low mechanical index (MI) have been successful at higher MI the behaviour of MBs is still not well understood. Understanding and predicting the response ofMBs to medical ultrasound can lead to improvements in the clinical use of MBs through improved contrast agent design or improved signal processing. Numerical models were developed to compare to three specific cases; 1) Rigid shelled contrast agents 2) Lipid shelled contrast agents 3) Responses from lipid shelled contrast agents that are hit by subsequent driving pulses. Three models were used to compare to the responses from single rigid shelled contrast agents. Two of these models have been used before and the third was developed based on the optical observations of the responses of these rigid shelled agents at these MI. Two shelled models were used to compare to the response of single lipid shelled MBs. Using statistical methods the parameters defining the shell properties were found. The parameters that gave best agreement with the lipid shelled data was then used with a model to account for the molecular diffusion of gas from a MB and a new model to account for the optically observed shedding of the shell from a MB to compare to the multiple response from single MBs. While the theoretical prediction of an acoustic response of a suspension of MBs or the radial oscillation of single MBs has been compared before to experimental data, the successful comparison of the acoustic response of single MBs to the theoretical prediction is the first of it’s kind known to the author. The new theoretical model of the rigid shelled MB that was developed in this thesis gave better agreement with the experimental data than the other previously used models. The shell parameters of the lipid shelled MB were determined for the lowest driving amplitude and were in agreement with those measured previously from optical observations. Finally, the model for the shedding of the shell was shown to give quantitative agreement with the multiple acoustic responses from single MBs. When shedding of the shell was included the choice of constitutive equation for the shell was shown to strongly affect subsequent responses from the MB.
