   abstract = {Considering the possibility to overcome drug resistance by other treatment strategies than chemotherapy we investigated the susceptibility of three independently selected multidrug-resistant sublines of the T-lymphoblastoid leukemic cell line CCRF-CEM to lymphokine-activated killer (LAK) cells. We found that two of the multidrug-resistant sublines were significantly less susceptible targets to LAK cells. A third one, however, was as susceptible as the parental CCRF-CEM cell line. Moreover, a multidrug-resistant subline that reverted to an almost drug-sensitive phenotype was observed to be also revertant for resistance against LAK cells. We found an inverse relationship between the expression of the mdr1 gene (P-glycoprotein) and the susceptibility to LAK cells. Verapamil, a calcium channel blocker, while increasing the drug sensitivity of a multidrug-resistant subline, did not induce a reversal of the suppression of LAK susceptibility. The possibility of enhanced resistance to LAK cells of multidrug-resistant cells should be taken into account when one is looking for therapy strategies to overcome multidrug resistance.},

The lesions produced by the laser beam on the vitreous in an air tissue interface technique were remarkable for their ring-shaped vitreous condensations. The diameter and density of these condensations increased with irradiance. With the same irradiation parameters the lesions at the anterior hyaloid membranes showed greater size and density than those in the central area of the vitreous. These vitreous condensations were demonstrated to consist of heat-denatured collagen fibrils. For light microscopic evaluation of the vitreous a modified method of tissue processing according to Szent Gyorgi has proven optimal in reducing vitreous shrinkage from dehydration. This method of fixation and tissue processing appeared to be useful in evaluating lesions of the vitreous and their relationship to their surroundings.},

These changes could be of clinical relevance. Therefore, we measured the residual monomer content of intraocular lenses before and after generation of lesions by means of a short-pulsed Nd-YAG laser. Despite the explosive destruction of the lens surface caused by this type of laser, there is no measurable release of monomer in the sense of a depolymerization of the PMMA material, even when over 100 lesions are generated. The lesions generated on intraocular PMMA lenses with the Nd-YAG laser are predominantly of a mechanical nature and include the chipping away of small particles from the intraocular lens.},

   abstract = {Different kinds of damage can be produced by intense light irradiation of the retina. These types of damage can be separated into changes which are induced by photochemical or thermal effects in the tissue. Photochemical damage occurs mainly with intense irradiation of a few seconds or longer whereas thermal effects appear to prevail at irradiation times in the 1 ms to 1000 ms-range. Distinction between photochemical and thermal damage is very difficult because both types of injury appear as disorders in the retinal pigment epithelium and the outer segments of the photoreceptors. A thermal model has therefore been developed which takes into account the light absorption in the different layers of RPE and choroid and allows the calculation of the temporal development of temperature at each site and depth of the fundus. Model calculations are used to correlate exposure parameters (wavelength, irradiance, exposure time etc.) with the resulting temperature profiles. This correlation leads to a better distinction between exposure limits for thermal and photochemical damage of the retina.},

Probit analysis showed a very precise determination of the threshold values based on ophthalmoscopical visibility.

   abstract = {Methotrexate (MTX)-resistant sublines of malignant human cells were selected in vitro by stepwise increase in drug concentration in the medium. By this procedure a subline of Burkitt's lymphoma cells (RAJI) was made 290-fold resistant (RAJI/MTX-R), T-cell leukemia cells (CCRF-CEM) were obtained 210-fold resistant (CEM/MTX-R), and 3 MTX-resistant human osteosarcoma lines were selected: TE-85/MTX-R (19-fold resistant; relative to wild-type); MG-63/MTX-R (8-fold resistant); and SAOS-2/MTX-R (200-fold resistant). We also studied a B-cell lymphoblastoid line, WI-L2/m4, that was 13,000-fold resistant. Assay of cellular dihydrofolate reductase (DHFR) showed the following pattern of activity in resistant cell lines, relative to parental cell activity: RAJI/MTX-R, 550-fold increased; CEM/MTX-R, unchanged; TE-85/MTX-R, 4-fold increased; MG-63/MTX-R, 6-fold increased; SAOS-2/MTX-R, unchanged; and WI-L2/m4, 110-fold increased. Measurement of MTX membrane transport showed decreased uptake in CEM/MTX-R and SAOS-2/MTX-R, relative to parental cell lines. The other DHFR-overproducing cells all gave normal initial MTX uptake rates but increased total uptake. The DHFR-overproducing lines all had significant cross-resistance to both metoprine and trimetrexate; the two lines with defective MTX transport were not cross-resistant, and the CEM/MTX-R cells showed collateral sensitivity to these agents. Only minor cross-resistance to homofolic acid was found in all MTX-resistant lines. The highly MTX-resistant RAJI/MTX-R and WI-L2/m4 cells showed minor cross-resistance to the dual inhibitor of thymidylate synthetase and DHFR, CB3717 (5- and 15-fold, respectively). These studies demonstrated that, depending upon the mechanism of resistance, MTX-resistant human tumor cells may be effectively killed by antifolates with different routes of uptake into cells, or with a different enzyme target. Thus, there are at least three functionally distinct classes of folate antagonist with antitumor activity.},

A distinction is made here between indirect methods such as area coagulation and direct methods with which specific vessels are treated. Whereas clinical tests involving vessel coagulation with pigmented epithelium absorption have already been carried out more or less successfully, selective vessel coagulation with hemoglobin absorption is still largely at the experimental stage. Our own experiments on animals have shown, however, that with the selection of a suitable coagulation technique and the use of suitable exposure parameters, vessel occlusion can be induced with the argon laser. To achieve this, shortening of the exposure times is particularly necessary.},

   abstract = {A knowledge of the quality of the ocular optical system is of primary importance in light- and laser-photocoagulation of the fundus. A study was therefore undertaken to determine the minimal spot size of a Helium-Neon laser focused on the retina of rabbits: freshly enucleated eyes were carefully mounted in a specially designed eye holder. A small hole was then trepanized through the sclera and neural retina in the macular region. A minimal spot was produced on the retina and the spot size was measured by scanning the intensity distribution of an enlarged image. It was shown that a diffraction limited spot size can be obtained under certain circumstances. The light scattering out of the focus, however, is about fify percent.},

Long-term observations revealed some decrease in size of developing localized opacification and a healing of the defect by outgrowing lens epithelium with the formation of a new capsule. The rupture of the posterior capsule led to a slowly progressive opacification with little intraocular macrophage reaction.},

The uptake by this system is proved first of all by cross-resistance with tri-L-ornithine using oligopeptide-transport-deficient mutants, and secondly by antagonism tests demonstrating competitive reversal of the action of the antibiotic by several peptides which have been shown to be transported via the oligopeptide transport system, e.g. tri-L-alanine, tetra-L-alanine, tri-L-lysine, tri-L-serine, tri-glycine, glycyl-glycyl-L-alanine and the synthetic tripeptide L-azadenyl-aminohexanoyl-alanyl-alanine. On the other hand, there is no effect on the action of the antibiotic in antagonism tests with compounds which use different transport systems, such as L-alanyl-alanine, L-lysyl-lysine, glutathione and the synthetic amino acid azaadenylaminohexanoic acid, i.e. 2-amino-6-(7-amino-3H-v-triazolo-[4,5-d]-pyrimidin-3-yl)hexanoic acid. Another inhibitor of the glutamine synthetase, L-methionine-S-dioxide (methioninesulfone) could be converted into a tripeptide form by linkage to L-alanyl-alanine analogously to the tripeptide antibiotics described above. Whereas the free L-methionine-S-dioxide seems to be transported via the methionine transport system, the tripeptide form is transported via the oligopeptide transport system. Thus, this glutamine synthetase inhibitor can be taken up by the cell via two different transport mechanisms. Our results indicate that this could provide a synergistic effect. The syntheses of the new tripeptides L-azaadenylaminohexanoyl-alanyl-alanine and L-methionine-S-dioxidyl-alanyl-alanine were performed by dicyclohexylcarbodiimide couplings of the unusual N-protected L-alpha-amino acids azaadenylaminohexanoic acid and L-methionine-S-dioxide to L-alanyl-alanine-tert-butyl ester followed by common deprotection steps.

   abstract = {The effects of intense light produced by an argon laser, a helium-neon laser and a xenon are photocoagulator in the retinas of gray chinchilla rabbits, cynomolgus monkeys, and rhesus monkeys were studied clinically and histopathologically including electron microscopy. An improved experimental set-up was used allowing a very good consistency of the inflicted lesions. Threshold lesions were produced in chinchilla rabbits and cynomolgus monkeys by an argon laser and a helium-neon laser. The lesions were evaluated ophthalmoscopically and histograms were drawn indicating ophthalmoscopic ED50 values. For the two lasers examined these values were 12 and 17 mW, respectively, for exposure durations in the range of the blink reflex (125-150 msec). Histopathologically, ophthalmoscopic threshold lesions of both laser types showed evidence of thermal damage of the outer retinal half. This damage was principally identical in both species involving the retinal pigment epithelium and the full extension of the photoreceptor cells up to their synapses within the outer plexiform layer. The ophthalmoscopic threshold value was associated, therefore, with an irreversible loss of visual function within the retinal area concerned. No evidence for primary sites of significant energy absorption within the neural retina was found. The width of ophthalmoscopic threshold lesions was determined by measuring within the histologic sections with a microscope and a calibrated graticule the extension of damage at the level of the retinal pigment epithelium and at the level of the outer nuclear layer. In the cynomolgus monkey for ophthalmoscopic argon laser threshold lesions the extension at the level of the RPE was 70-80 mum in diameter and at the level of the outer nuclear layer it was 40-50 mum in diameter. Laser lesions that had a diameter of 60 mum at the level of the RPE and of 30 mum at the level of the outer nuclear layer were ophthalmoscopically subvisible. It is concluded that probably also in man such laser lesions, as well as various other pathologic changes of this size or smaller, cannot be evaluated by clinical ophthalmoscopy. The ophthalmoscopic threshold was correlated with a histopathologic threshold as defined by minimal histopathologic damage. Very likely, such damage lies within the range of functional recovery, and the histopathologic threshold demarcates at the same time the decisive functional threshold. The conversion ratio between histopathologic-functional and ophthalmoscopic threshold for argon lesions in cynomolgus monkeys was somewhat greater than 3, e.i. the ophthalmoscopic threshold was more than 3 times higher than the histopathologic-functional threshold. Using this data together with additional biologic and optical considerations, a safety threshold for man for cw-lasers within the visible spectrum was estimated to be 1-2 mW.},
