A Study Of 5-Aminolevulinic Acid And Its Methyl Ester Used In In Vitro And In Vivo Systems Of Human Bladder Cancer, Vanaja Manivasager, Paul Wan Sia Heng, Jinsong Hao, Wei Zheng, Khee Chee Soo, Malini Olivo
A Study Of 5-Aminolevulinic Acid And Its Methyl Ester Used In In Vitro And In Vivo Systems Of Human Bladder Cancer, Vanaja Manivasager, Paul Wan Sia Heng, Jinsong Hao, Wei Zheng, Khee Chee Soo, Malini Olivo
Pharmaceutical Science and Research
The use of 5-aminolevulinic acid and its esters to induce endogenous porphyrins for the purpose of detection of epithelial cancers is being studied extensively in many centres around the world. The challenge is to prepare an efficacious formulation for the purpose of cancer detection. Photodynamic diagnosis of cancer using 5-aminolevulinic acid (ALA) and its ester derivatives is being actively investigated. In this study, we compared ALA with ALA methyl ester (AME) derivative in terms of PpIX fluorescence intensity in in vitro and in vivo systems of bladder carcinoma. For the in vivo system consisting of RT112 xenografts, the modes of …
Macro-Microscopic Fluorescence Imaging Of Human Npc Xenografts In A Murine Model Using Topical Vs. Intravenous Administration Of 5-Aminolevulinic Acid, Vanaja Manivasager, Paul Wan Sia Heng, Jinsong Hao, Wei Zheng, Khee Chee Soo, Malini Olivo
Macro-Microscopic Fluorescence Imaging Of Human Npc Xenografts In A Murine Model Using Topical Vs. Intravenous Administration Of 5-Aminolevulinic Acid, Vanaja Manivasager, Paul Wan Sia Heng, Jinsong Hao, Wei Zheng, Khee Chee Soo, Malini Olivo
Pharmaceutical Science and Research
The use of 5-aminolevulinic acid to induce endogenous porphyrins for the purpose of detection of epithelial cancers is being studied extensively in many centres around the world. The challenge is to prepare an efficacious formulation of 5-ALA for the purpose of cancer detection. In this study, we compared two formulations of topical 5-ALA applications with intravenous administration in NPC/CNE-2 xenografts on balb/c nude mice. One of the formulations was a gantrez muco-adhesive patch and the other was a polyvinyl-pyrolidone muco-adhesive patch. The Karl Storz fluorescence endoscopy system was used to obtain macroscopic fluorescence images. Microscopic fluorescence imaging was done by …
