The multiple evanescent white dot syndrome MEWDS ; is defined as an entity whose clinical progression is self-limited, benign, of unknown etiology and rarely recurrent. Nevertheless, the severe loss of vision secondary to a choroidal neovascularization has been described in the literature 1, 2 ; . The present case presumably involves a recurrent MEWDS that developed a subretinal neovascular membrane SRNV ; thirteen years after the initial episode.

Hand panels ; and for the expression of specific differentiation markers Figs 5 and 6 ; . In response to retinoic acid, all cultures lost their ability to grow in methylcellulose, irrespective of whether or not they expressed lamin A. Instead of forming large colonies, the retinoic acid-treated cells essentially remained as single cells, as expected for differentiated EC derivatives Fig. 4B, D and F ; . This result strongly suggests that cells expressing chicken lamin A were still capable of differentiating in response to retinoic acid. To corroborate the above conclusion by more stringent criteria, the differentiation state of the various P19 cell lines was monitored by studying the expression of characteristic differentiation markers, using appropriate antibodies for indirect immunofluorescence micoscropy Fig. 5 ; and immunoblotting Fig. 6 ; . The transfected lines Al and A2 expressed chicken lamin A, irrespective of whether or not they had been induced to differentiate with retinoic acid, whereas cells transfected with vector only Kl ; were negative Fig. 5A-C; Fig. 6 ; . In contrast, murine lamin B was detected in similar amounts in all cell lines, regardless of their states of differentiation Fig. 6 ; . These results demonstrate the specificity of the anti-lamin A monoclonal antibody used here for the chicken protein. In agreement with previous reports Lebel et al. 1987; Stewart and Burke, 1987; Stuurmann et al. 1989 ; , undifferentiated P19 cells did not express detectable levels of endogenous mouse lamins A and C Fig. 5D ; , while the expression of these proteins was induced during differentiation Fig. 5E and F ; . Interestingly, induction of the murine A-type lamins was not detectably influenced by the presence of ectopically expressed chicken lamin A in the Al and A2 transfectants, indicating that there was no significant down-regulation of lamin A expression due to feedback controls. Differentiation of P19 cells is also accompanied by induction of the cytoplasmic intermediate filament IF ; protein vimentin and a cytoplasmic endo A cytokeratin, the latter protein being recognized by the antibody TROMA 1 Kemler et al. 1981 ; . Both markers are virtually absent in undifferentiated P19 cells, but their expression increases dramatically during differentiation Fig. 5J-O; Fig. 6 ; . In contrast to the above proteins, which are all induced during differentiation, ECMA7 also called SSEA1; Solter and Knowles, 1978 ; represents a cell surface antigen that is expressed in undifferentiated cells, but not in differentiated cells Solter and Knowles, 1978 ; . ECMA7 antigen was readily detectable in the lamin A-transfected cell lines that had not been exposed to retinoic acid, confirming that these cell lines are in an undifferentiated state Fig. 5G; Fig. 6 ; . After retinoic acid-induced differentiation, expression of ECMA7 dropped drastically Fig. 5H and I; Fig. 6 ; . Having established that expression of lamin A in undifferentiated P19 EC cells did not abolish the potential of these cells to differentiate in response to retinoic acid, we asked whether the kinetics of the differentiation process might be affected. For this purpose, cells were induced to differentiate with retinoic acid and the expression of vimentin and ECMA7 was monitored by immunoblotting. As shown in Fig. 7, the appearance of vimentin as well as the disappearance of ECMA7 occurred with indistinguishable kinetics in both control Kl ; and lamin A-expressing cells Al ; . In order to compare the growth kinetics of the different clones, we also determined the total cell number at every time point. When retinoic acid was omitted, both Al and Kl cells grew with similar, Lamin A expression in carcinoma cells 593 and muse.

11 ; , and prompted alternative strategies, including immunotoxins and bispecific antibodies, for CD30-targeted treatment of HD 28, 29 ; . In contrast to these findings, we have observed that the anti-CD30 mAb AC10 and its chimeric form SGN-30 were effective at inhibiting the growth of HD lines in vitro and in xenograft models. Recent studies indicate that, as with other receptor-mediated responses, the strength of the CD30 signal varies, depending on the use of soluble or immobilized mAb, and that this may determine sensitivity to growth arrest or apoptosis 13, 14 ; . To parallel earlier studies 11 ; , we examined the effect of the murine AC10 on HD cells using immobilized mAb. The effects were stronger when AC10 or SGN-30 were immobilized to the tissue culture wells as compared with solution. Similarly, as shown for SGN-30, the effects were enhanced when cross-linked using a secondary antibody. The significance of receptor cross-linking has been described previously for other TNF superfamily members including TNF- and CD40, which require receptor multimerization to bring about TNF-R-associated factor TRAF ; mediated signaling 30 32 ; . may be possible that cross-linking, rather than immobilization of mAbs, could reflect the situation in vivo in which Fc receptor-mediated clustering of SGN-30 bound to CD30 could induce a similar effect. In this manner, CD30 clustering could then provide transduction of growth arrest and apoptotic signals that, in addition to the mAb accessory functions of antibody-dependent cell-mediated cytotoxicity and complement-mediated cytotoxicity, would promote antitumor activity. Importantly, the activities of SGN-30 observed on HD cells in culture were reflected by its efficacy in the treatment of xenograft models of solid and disseminated HD at doses ranging from 1 to 4 mg kg. These doses of SGN-30 were well tolerated with no signs of toxicity and single doses of up to 100 mg kg have been administered to mice without any toxicity data not shown ; . A significant advantage to mAb therapy for the treatment of diseases in man is the potential to specifically target diseased cells with little or no systemic toxicity. This should be especially true with target antigens such as CD30, which are highly expressed on diseased cells but have limited expression in normal tissues. SGN-30 has been administered i.v. to cynomolgus monkeys at 100 mg kg with no signs of toxicity.5 On the basis of the antitumor activities reported here, the restricted nature of CD30 expression on normal cells, a favorable tolerance profile in nonhuman primates, and the need for additional therapies for patients with relapsed HD, SGN-30 is being developed for clinical trials.

George stated that we have to prioritize. Some code changes could be done later. The new code is a living document. We need to keep up with technical advancements. Dottie reminded us that we have to do the justifications. Ron said that there is a list of advisory experts to assist us. During this discussion Scott stated that modifications which are simplifications would not require the SAPA paperwork. There were concerns regarding plumbers boards and licensed plumbers. Cheryl stated that since the licensure of plumbers is on an individual municipality level, the new codes will not change that. The members decided that each would analyze the codes or ask others in their organization ; . The members asked for copies of the present codes and CD's of the new codes. George agreed since it is in the interest of the taxpayers. George asked if the group thought a court reporter would help. Ron reminded us that only one person can talk at a time and it formalizes the process. A public hearing has been scheduled on Wednesday, May 3 between 1 and 4 pm, during the Hudson Valley NYSBOC conference at the Holiday Inn in Fishkill. Ron stated that each subcommittee will report on issues and focus areas, there will be a period for public comment, and a panel consisting of two members of each subcommittee to answer questions. The next meeting is scheduled for April 25, 2000, 9 till 4 pm.

Degree of wear may range from slight enamel facets to pulp exposure, with its pernicious sequelae. The plane of wear on the inferior teeth slants obtusely from the linguo-occlusal angle toward the buccocervical margin of the enamel; that on the superior teeth is the reverse. Extensive attrition exposing the dental pulp is a concomitant of senility with some races. The betel-nut concoction, especially because of its lime content, has an abrasive effect on the teeth, but not nearly so great as might be imagined, for the habit was to hold the bolus in the buccal vestibule rather than actively to chew it. The food in Micronesia was cooked and soft, and apparently no abrasives were introduced in the preparation. Individuals in this group under twenty-five showed very slight wear; those under forty but little; while seven old individuals had teeth worn to exposure of the pulp-fourth degree attrition-with nineteen resultant periapical osseous lesions and nafcillin.
Consisted of 100 g of algal tissue wet wt ; to 100 ml of buffer solution. The tissue and buffer were added together slowly over a period of 2 min to insure maximum breakage of the tough cell walls, and the resulting mixture was passed through 4 layers of cheesecloth. In nmost instances the plants were first cut into small pieces before being mixed with the buffer. This procedure took place in a 50 cold room. The resulting homogenate was then centrifuged at 12.1009 for 20 min in a refrigerated centrifuge. Higher speeds and longer times were attempted but these did not influence subsequent enzyme activity. The electrometric system used for measuring enzyme activlitv is a modification of a more complex apparatus built previously by Davis 4 ; . Beckman glass and calonmel electrodes were connected to a Carv model 31 vibrating reed electrometer, and this served as the pH meter. The electrometer in turn was connected to a Bausch and Lomb 10 mV VOM 5 chart recorder. This system registers changes in E.M.F. and the graph is therefore a millivolt scale. Hydrogen ion concentrations were determined bv calibrating Nvitlh standard buffers. Previous to this, a manometric device based on the familiar boat method 12 ; was tested witlh several algal extracts and wvith purified beef red blood cell enzyme. but the system did not give sufficiently precise results. The reaction measured is a dehydration whereby CO., is evolved after NaHCO3 is mixed with the homogenate. AIajor disadvantages of this method are that the enzyme may be partialily denatured due to the vigorous shaking of the reaction vessel, the rate measurement is strongly dependent upon rate of CO., removal from solution, and carbonic anhy-drase activity mav be modified by the strength of buffer employed 0.1-0.2 M ; 6 ; . The reaction vessels were 20 ml pyrex beakers. They were chilfled in a 100 refrigerator before use, as were all soltutions and oLher glassware. Before everv test 5 ml of the homogenate plus 0.5 ml of buffer, dithiothreitol DTT ; 3 10-3 M final conc.; dissolved in the buffer ; or p-chloromercuriphenylsulfonic acid PCMPS ; 4 10-4 M final conc.; dissolved in the buffer ; , were injected by syringes into the beakers. The DTT and PCMPS were incubated with the homogenates for 30 min periods. Five min before the run, the beaker wvith solution would be set in a 10 cold bath and the pH electrodes lowered into it. Stirring was started at this time with a Teflon-coated magnetic stirring bar 8.0 mm ; slowing turning over ; controlled by a device lying below the wvater level. The stirring was found necessary to condition and stabilize the electrodes.
5.13. P450 MONO-OXYGENASE IN THE SKIN Although cytochrome P450 arachidonic acid mono-oxygenase has been known to be present in other tissues for many years, a novel P450 enzyme, CYP2B19, was recently discovered in fetal murine skin. CYP2B19 was shown to be exclusively expressed in differentiated keratinocytes of the epidermis, hair follicles and sebaceous glands. This mono-oxygenase can serve as keratinocyte differentiation marker. Recombinant CYP2B19 metabolizes AA and generates epoxy-eicosatrienoic acids EETs ; and HETEs. In endothelial cells, EETs activate ion channels and increase the cytoplasmatic Ca2 + concentration. It could be possible that skin CYP2B19 participates in Ca2 + dependent intracellular signalling pathways and in the formation of eicosanoids 145 and naloxone.

Thirdly, there is mounting evidence that serum vitamin assays lack sensitivity and specificity although they are still regarded as standard, first-line methods of screening.11, 12, 15, 16 Without more sensitive and reliable tests such as metabolite assays and the in vitro deoxyuridine suppression test, the detection of early and subtle stages of nutritional deficiency and the documentation of the exact type of vitamin deficiency is not possible. Despite these shortcomings, the present study revealed some important information. Firstly, it demonstrated cobalamin deficiency as the major cause of megaloblastic anaemia in a cohort of Chinese patients at a regional hospital in Hong Kong. Judging by levels of serum cobalamin and RBC folate only, 88.5% of the patients were identified as having cobalamin deficiency, 1.9% as having folate deficiency, and 9.6% as having combined deficiencies. According to the 'methylfolate trap' or the 'tetrahydrofolate starvation' hypotheses, 8, 11-"--that the interaction of folate and cobalamin metabolism can bring about a reduction in the RBC folate level when there is cobalamin deficiency--the 9.6% of patients with both low serum cobalamin and RBC folate levels may have either combined deficiencies or cobalamin deficiency alone. Thus, in the absence of other supplementary tests, 98% of the patients can be estimated to have cobalamin deficiency, either alone or with concomitant folate deficiency. Folate deficiency was estimated to occur in 2% to 12% of the patients. The paucity of folate deficiency could be related to the fact that we did not screen obstetric, paediatric, or psychiatric patients in our study. In addition, tropical sprue coeliac disease is rare among the Chinese population, and the nutritional status of most people in Hong Kong is satisfactory. The second important finding of the study was that pernicious anaemia was a major cause of cobalamin deficiency among the patients. The diagnosis of pernicious anaemia in the present study was tentatively made on the demonstration of 1 ; megaloblastic haemopoiesis, either in the blood or in the marrow, 2 ; cobalamin deficiency by serum vitamin assay, 3 ; the presence of serum antibodies against IF and or GPCs, 4 ; atrophic gastritis, and 5 ; a positive result from the Schilling test.1'17 No attempt was made to obtain direct evidence of IF deficiency. At the time of analysis, only the first three criteria had been fulfilled completely. If we assume the presence of anti-IF antibodies to be a specific indicator of pernicious anaemia, and that of anti-GPC antibodies to be sensitive but less specific, 1, 8 then the 32 61.5% ; patients who had anti-IF antibodies would have definite pernicious and murine.
Inhibition of ErbB2 Signaling Abrogates Transcriptional Activation by ERRa1 We next investigated whether blocking specific components within the ErbB2 signaling pathway led to inhibition of transcriptional activation by ERRa1. BT-474 cells were cotransfected with the reporter gene sets and expression plasmids as described in Fig. 2D lanes 1-4 ; . They were subsequently incubated for 40 h in estrogen-free medium supplemented with 20 Ag mL nonspecific murine IgG as a control, the humanized anti-ErbB2 mAb trastuzumab at 20 Ag mL, or the small-molecule EGFR inhibitor gefitinib at 1 Amol L Fig. 7A ; . Gefitinib blocks transphosphorylation of ErbB2 by EGFR, thereby indirectly inhibiting ErbB2 35 ; . As expected, overexpression of ERRa1 in the IgG-treated cells led to a 4- to 5-fold activation of ERE 5 ; -regulated transcription Fig. 7A, lanes 3 and 4 versus lanes 1 and 2 ; . Incubation with trastuzumab led to an f85% reduction in ERE-regulated transcription by ERRa1 Fig. 7A, lanes 7 and 8 versus lanes 3 and 4 ; to a level even below that observed in the presence of only endogenous ERRa1 in the absence of the drug Fig. 7A, lanes 1 and 2 ; . This large reduction was probably due to treatment with trastuzumab altering as well the transcriptional activity of the endogenous ERRa1 Fig. 7A, lanes 5 and 6 versus lanes 1 and 2 ; . Incubation with gefitinib led to an even and naltrexone.
The company's exports grew by 21% to 6.3 million. Sales in Russia and other ex-Soviet republics accounted for almost 40% of total exports, followed by those in countries of central and eastern Europe 35% ; . However, sales in the former region declined by 3% - the 11% reduction of exports to Russia to million was balanced by their 13% rise in Ukraine to .8 million ; and by sales in other ex-Soviet republics which grew by 20% to .6 million. Poland was Egis's largest market in CEE, with sales of .4 million + 13% ; , followed by Romania .8 million, + 22% ; and the Czech Republic .6 million, + 24% ; . In total, sales in the region increased by 18% to 50.5 million. Sales of finished pharmaceuticals to other countries have more than doubled to .5 million and those of bulk chemicals and ingredients rose by 5% to million.
