  • Patent number: 11246477
    Abstract: A fluorescence endoscopic method for visualization of colorectal tissue using a fluoroquinolone antibiotic and a method for diagnosis of lesions of colorectal tissue using the same. The fluorescence endoscopic method for visualization of colorectal tissue includes staining goblet cells of the colorectal tissue with moxifloxacin, which is a fluoroquinolone antibiotic, and exciting the stained goblet cells with single photons in the near UV region or in the visible region, followed by fluorescence endoscopic photographing of the goblet cells, thereby enabling acquisition of morphological information on living tissue without damage to or destruction of the colorectal tissue, while allowing diagnosis of lesions of the colon based on the morphological information on living tissue such as information on the distribution of the goblet cells.

  • Patent number: 10859498
    Abstract: A method for visualization of conjunctival cells using fluoroquinolone antibiotics and a method for diagnosis of ocular lesions using the same. The method for visualization of conjunctival cells using fluoroquinolone antibiotics includes staining goblet cells of ocular conjunctiva with moxifloxacin, which is a fluoroquinolone antibiotic, and exciting the stained goblet cells with single photons in the near-UV region or in the visible region, followed by fluorescence photographing of the goblet cells, thereby enabling acquisition of morphological information on living tissue without damage to or destruction of the ocular conjunctiva.

  • Publication number: 20190059737
    Abstract: Disclosed are an imaging method using fluoroquinolone antibiotics and an imaging device for the same, in which biological tissue is stained with Moxifloxacin as one of fluoroquinolone antibiotics, and the stained biological tissue is subjected to fluorescent image-capture through single-photon excitation with either near-ultraviolet or visible wavelength light instead of either a middle-ultraviolet light source or a femtosecond near-infrared laser device, thereby obtaining morphological information of cells in the biological tissue at a high speed without damage.
