In vivo action spectra, absorption and fluorescence excitation spectra of photosensitizers for photodynamic therapy.
Recently the importance of measuring in vivo action spectra for photodynamic therapy (PDT) with various photosensitizers was pointed out in this journal [1]. It was shown that the effect of PDT with zinc phthalocyanine tetrasulphonic acid (ZnPcS4) increases considerably when the wavelength of the activating light is increased from 680 to 692 nm. In this regard a further comparison with haematop...

Lux UV with a Philora HPW 19@5-watt mercury vapor lamp). The intensity and the penetration power of the blue fluorescence was estimated by using an arbitrary gradation (cf. Fig. @). However, spectroscopic estimations were not made, and therefore it is unknown whether the blue fluores cence in the tissues depends on unchanged BP or on its blue fluorescent metabolites. Bearing this in mind, refer...
متن کاملRelationship between the Absorption and Emission Spectra and the "Red Drop" in the Action Spectra of Fluorescence In Vivo.
The Stepanov equation, relating the intensity of emission, f(e)(v), at a given frequency, and that of absorption, k(v), at the same frequency, is applied, in its modified form (see equation 3 in text) to suspensions of Chlorella, Porphyridium, and Anacystis and to chlorophyll solutions. This application can reveal whether the yield of fluorescence, Phi(v), is constant, or changes with frequency...

متن کاملpostnatal studies of bats (pipistrellus kuhlii and miniopterus schreibersii) & histomorphology and histochemistry studies of organs and diseases of (neurergus microspilotus and n. kaiseri)
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
