In this paper, we demonstrate that the penetration depth under two-photon excitation is limited by the strength of two-photon fluorescence and is not necessarily larger than that under single-photon excitation, although image resolution is much higher in the former case.

The use of seeding scaffolds has facilitated advances in tissue engineering. We found that multiphoton microscopy is useful in imaging commonly used tissue engineering scaffolds such as polyglycolic acid (PGA).

The time-of-flight (TOF) method and the diffuse reflectance (DR) method were applied for the characterization of optical parameters in living tissue in the region of 1-2 /spl mu/m. The absorption coefficient obtained by the TOF method was consistent with the content of water in the tissue. The DR measurement indicates the very large attenuation in the wavelength region above 1.4 /spl mu/m. In this region, it is suggested that the optical transport does not diffuse well and it is localized at the light source.

We demonstrated in vivo targeted gene delivery to rat skin by direct irradiation with nanosecond laser pulses. Expressions of enhanced green fluorescent protein (EGFP) were observed only in the area irradiated with laser pulses.

This paper mainly describes the database design for an accurate, reliable and clinical technique to wound management. The wound size assessment should include length, width, area and perimeter. The program enables the user to calculate the linear distance (width and length) of an image. The mouse is used to trace the cursor around the image outline (perimeter). Manual calibration of the measurement can be carried out to increase wound assessment accuracy and reliability. In addition, at any time, a patient's wound images and image data may be viewed in chronological order for the purpose of comparison. This provides a visual and informative record of changes to the wound over time. Finally, wound measurement software provides all the features necessary to work with databases, such as entering new data, and modifying or viewing existing data.

A photoelastic modulated ellipsometry combined with SPR technique is proposed. In addition to monitor the biological interactions in real time, we also installed a post flight analysis technique to analyze the same system synchronously.

Studies in the past have confirmed the safety and efficacy of photodynamic therapy (PDT) in the treatment of various human cancers. Because of the concern for cosmetic and functional preservation, PDT seems to be particularly suited for head and neck tumor treatment. Results from previous studies are promising. Good cosmetic and functional outcomes can be achieved without compromising the patients' survival. PDT is a therapeutic option that may prove a useful addition to the armamentarium of the integrated head and neck oncology team.

Images of mitochondria inside living cells with high spatial and temporal resolution could be visualized with specific functional fluorescent probes coupled with laser scanning confocal microscope. The interactions between mitochondria and other parts of cells remain nature and unaltered with this method. The effects of mitochondrial function changes on other parts of cells can best be investigated with this approach.

We present autofluorescence modeling of different cervix tissue dysplasia for clinical diagnosis. We used double integrating sphere system and inverse adding-doubling (IAD) method to evaluate tissue optical parameters (absorption coefficient, /spl mu//sub a/, scattering coefficient, /spl mu//sub s/) of different cervix dysplasia. We used fluorescence Monte Carlo model included absorption coefficient and scattering coefficient from IAD and integrate sphere, to simulate autofluorescence spectra. The results show the increasing thickness of abnormal tissue on the cervical epithelium accompanied with the decreasing in autofluorescence intensity, in collagen peak (390 nm) and in NADH peak (460 nm), along with the lesion developments.
