We demonstrated that a quickly growing hamster skin melanoma developed a tumor after autologous implantation into the anterior chamber of the eye. Tumor cells were seen invading all the surrounding tissues, including the iris, ciliary body, choroid and cornea. Histological examination confirmed the presence of numerous blood vessels of large diameter. Their walls were very thin, thus only the endothelium could be identified using light microscopy. Macrophages, microemboli and extravasations were present within the tumor mass.

Ammonium salt of N-(dithiocarboxy)sarcosine (DTCS) chelated to ferrous salt was tested as an NO-metric spin trap at room temperature for ex vivo measurement of NO production in murine endotoxaemia. In a chemically defined in vitro model system EPR triplet signals of NO-Fe(DTCS)2 were observed for as long as 3 hours, only if samples were reduced with sodium dithionite. This procedure was not necessary for the ex vivo detection of NO in endotoxaemic liver homogenates at X-band or in the whole intact organs at S-band, whereas only a weak signal was observed in endotoxaemic lung. These results suggest that in endotoxaemia not only high level of NO, but also the redox properties of liver and lung might determine the formation of complexes of NO with a spin trap. Nevertheless, both S- and X-band EPR spectroscopy is suitable for NO-metry at room temperature using Fe(DTCS)2 as the spin trapping agent. In particular, S-band EPR spectroscopy enables the detection of NO production in a whole organ, such as murine liver.

Standard ocular tumor treatment includes brachytherapy, as well as proton therapy, particularly for large melanoma tumors. However, the effects of different radiation types on the metastatic spread is not clear. We aimed at comparing ruthenium (106Ru, emitting β electrons) and iodine (125I, γ-radiation) brachytherapy and proton beam therapy of melanoma implanted into the hamster eye on development of spontaneous lung metastases. Tumors of Bomirski Hamster Melanoma (BHM) implanted into the anterior chamber of the hamster eye grew aggressively and completely filled the anterior chamber within 8-10 days. Metastases, mainly in the lung, were found in 100% of untreated animals 30 days after enucleation. Tumors were irradiated at a dose of 3-10 Gy with a 106Ru plaque and at a dose of 6-14 Gy using a 125I plaque. The protons were accelerated using the AIC-144 isochronous cyclotron operating at 60 MeV. BHM tumors located in the anterior chamber of the eye were irradiated with 10 Gy, for the depth of 3.88 mm. All radiation types caused inhibition of tumor growth by about 10 days. An increase in the number of metastases was observed for 3 Gy of β-irradiation, whereas at 10 Gy an inhibition of metastasis was found. γ-radiation reduced the metastatic mass at all applied doses, and proton beam therapy at 10 Gy also inhibited the metastastic spread. These results are discussed in the context of recent clinical and molecular data on radiation effects on metastasis.
