This paper demonstrates that polarization microscopy can be a very useful tool for observing the dissolution processes of electrospun drug-loaded nanofiber mats, and thus providing useful information for preparing drug-loaded nanofibers with high quality. With icariin as the model active pharmaceutical ingredient and PVP K30 and K60 as filament-forming matrix, three different types of drug-loaded...
To explore the inhibition of juglone in Qinglongyi on A-549 cells in vitro, MTT assay was used. Laser confocal scanning microscope was used to observe apoptotic morphology. Changes of cell cycle are studied by flow cytometry analysis. The result of MTT assay showed that juglone had a marked growth inhibition in A-549 cells and the IC50 is respectively 3.4 × 10-5 mol/L, 1.8 × 10-5 mol/L and 2.6 × 10...
The purpose of this article was to observe interaction between drug and cancer cell with fluorescence probes and molecular imaging technology. In order to study the effect of cell growth and apoptosis morphology of Human gastric adenocarcinoma SGC-7901 induced by n-butanol extract from Capparis spionosa L. (CSBE), laser scanning microscopy was employed to observe apoptosis imaging. In addition, the...
To study the effect of Saponins of asparagus on HepG2 apoptosis, reactive oxygen species (ROS) and mitochondrial membrane potential (Δψm) levels. Saponins of asparagus with different concentration was treated with HepG2 at different time, MTT assay was used to detect inhibitory rate, fluorescence staining was used to observe apoptosis morphology, flow cytometry was used to detect apoptosis rate and...

The distribution, directionality and motility of the actin fibers control cell shape, affect cell function and are different in cancer versus normal cells. Quantification of actin structural changes is important for further understanding differences between cell types and for elucidation of the effects and dynamics of drug interactions. We have developed an image analysis framework for quantifying...
In order to understand the effect of microbubble driven by ultrasound to the skin, we tried to investigate the effect of bubble behaviors to the skin-life soft material, bovine gelatine MDCK cells cultured. Using high-speed video camera and fluorescene microscope, the bubble behaviors and the effect to the cells were investigated. Based on observations using high-speed video camera, it was found that...
To explore the inhibition of juglone in Qinglongyi on A-549 cells in vitro, MTT assay was used. Laser confocal scanning microscope with AV-PI staining was used to observe apoptotic morphology. Changes of cell cycle are studied by flow cytometry analysis. The result of MTT assay showed that juglone had a marked growth inhibition in A-549 cells and the IC50 is respectively 3.4 times 10-5mol/L, 1.8 times...
To study the effect of Saponins of asparagus on HepG2 apoptosis, reactive oxygen species (ROS) and mitochondrial membrane potential (Deltapsim) levels. Saponins of asparagus with different concentration was treated with HepG2 at different time, MTT assay was used to detect inhibitory rate, fluorescence staining was used to observe apoptosis morphology, flow cytometry was used to detect apoptosis rate...
To study the effect of growth inhibition and induction of apoptosis in sarcoma 180 cells by juglone in vivo. S180 tumor-bearing mice were set up to investigate the effects of juglone on tumor growth inhibition and apoptosis. After HE staining, the pathomorphologic changes of tumor cells were observed by optical microscope. The ultrastructural changes of tumor cells were observed by transmission electron...
A transparent artificial cornea derived from biological material is the ultimate goal of corneal research. Attempts at artificial corneal constructs produced from synthetic polymers have proved unsuccessful due to lack of biocompatibility and ability to integrate into the tissue. We have designed a corneal model derived from collagenous biological materials that has several advantages: it has low...
