Sallam 2 ; 1 ; National Cancer Institute, Dept. of Medical Oncology, Cairo, Egypt 2 ; National Cancer Institute, Cairo, Egypt Squamous cell carcinoma SCC ; of the bladder is a rare disease worldwide. It has a distinct clinico-pathological profile that differs from the classic transitional cell carcinoma of the bladder.Few trials have been published on the role of chemotherapy in this disease , all of which had extremely small patient numbers, . A total number of 73 patients with locally advanced, metastatic and or recurrent bilharzial-related SCC were treated in a series of clinical trials over the last 5 years using two different single agents, and 2 different combination chemotherapy regimens. They were males 56 and 17 females, with a median age of 53 years range 29-66 years ; . Twenty five patients had inoperable disease, 11 had metastatic and local disease , 10 had local recurrence , 5 had local recurrence and distant metastases and 22 had metastatic disease after radical surgery. Using single agent therapy, Epidoxorubicin 120 mg m2 i.v. every 3 weeks ; , and Taxotere 100 mg m2 i.v. every 3 weeks ; , were given to 13 patients in each group . A third group of 25 patients received a combination EV-EH ; of Epidoxorubicin 120mg m2 i.v. d1 ; and vincristine 1.4 mg m2 i.v. days 1 and 8 ; , alternating with etoposide 100 mg m2 i.v. infusion over 1 hour days 1 to 5 ; and ifosfamide 1800 mg m2 i.v. infusion over 2 hours days 1 to 5 ; together with the mesna uroprotector every 3-4 weeks depending on patient tolerance.The last group of 22 patients has received gemcitabine 1000mg m2 ; on days 1, 8, and 15 and cisplatin 70 mg m2 ; on day 2 of every 28-day cycle GC ; . Of total of 59 evaluable patients, 13 22% ; had a partial, and 5 8 % ; a complete response, giving a response rate of 30 % .Toxicities were tolerable and manageable .Analysis of results in relation to chemotherapy type, showed that Epidoxorubicin, Taxotere single agents , EV-EH , and GC combinations gave overall response rates of 0 % 3 stable disease ; , 50 % 4 8 , 1CR ; , 40 % 8 20 , CRs ; , and 33 % 6 18 , CRs ; respectively. So, it may be concluded that advanced SCC of the bladder is relatively chemosensitive disease and a triplet of GC and taxtotere may further improve the outcome. Introduction: To investigate the influence of addition of rituximab to an intensified salvage program with autologous stem cell support we performed a matched pair analysis of two patients groups treated within phase II clinical trials according to age, duration of first remission, LDHLevel, clinical symptoms. The first group received sequential HDCT HDSCT ; . Pts in the second group treceived he same HDSCT plus rituximab R-HDSCT ; . Methods: Eligibility criteria for both group were: age: 1865 years, eligibility for HDCT, histologically proven CD20 + relapsed NHL. Treatment program starts with two cycles DHAP dexamethasone, cytarabine, cisplatin pts with CR or PR receive cyclophosphamide 4 g m2 ; followed by PBSC harvest; methotrexate 8 g m2 ; with vincristine 1, 4 g m2 ; and etoposide 2 g m2 ; followed by optional PBSC harvest. The final myeloablative course is BEAM with ASCT. Rituximab 375 mg m2 ; was given at the first day of to chemotherapy cycle. Results: From 80 patients enrolled in the pase II studies 17 pts were matched in each group. Median age in HDCT was 50 years 2465 ; and in R-HDCT 56 years 2365 ; . There were 13 76% ; pts with relapsed and 4 24% ; with refractory disease in each group. The majority of pts in both groups received CHOP-like regimens as first line treatment. The overall response rate OR ; at the final evaluation for all patients was: HDSCT 65% 59% CR and 6% PR ; vs R-HDSCT 77% 65% CR and 12% PR ; . The 2-year FF2F was 47% HDSCT ; vs. 73% R-HDSCT ; and the 2-year OS was 70% HDSCT ; vs. 82% R-HDSCT ; . The therapy toxicity was tolerable and comparable in both groups. Conclusions: The results of our analysis suggest better therapy outcome in pts treated with HDSCT with rituximab compared to pts treated with the same therapy regimen without rituximab. Randomizeds should confirm these data. Glycoprotein, is a member of the ATP-binding cassette ABC ; transporter superfamily 13 ; . The predicted structure of MRP1 differs from that of a typical eukaryotic ABC transporter such as P-glycoprotein P-gp ; . It contains a P-gp-like core region, which consists of two membrane-spanning domains MSDs ; , each containing six transmembrane TM ; -helices, and two nucleotide binding domains. However, MRP1 contains a third MSD predicted to consist of five TM -helices with an extracellular NH2 terminus and a cytoplasmic linker connecting the additional MSD with the core region 37 ; . Like P-gp, MRP1 confers resistance to many commonly used, structurally diverse natural product chemotherapeutic agents including anthracyclines, Vinca alkaloids, and epipodophyllotoxins 710 ; . However, several lines of evidence suggest that MRP1 and P-gp confer resistance to these drugs by different mechanisms. In vitro studies using P-gp-enriched membrane vesicles or purified reconstituted protein demonstrate that P-gp directly binds and transports its drug substrates in an ATP-dependent manner 11, 12 ; . Under similar conditions, MRP1 will only transport unmodified amphipathic drugs, such as vincristine and daunorubicin, in the presence of GSH in addition to ATP 1317 ; . In some cases, GSH appears to be co-transported with these compounds 15 ; . In addition to conferring resistance to natural product drugs, MRP1 actively transports many glutathione-, glucuronide-, and sulfate-conjugated organic anions in a GSH-independent manner 16 20 ; , although recent studies indicate that GSH may significantly enhance transport of some organic anion conjugates 2123 ; . Some of these conjugated compounds are potential physiological substrates, such as cysteinyl leukotriene C4 LTC4 ; and 17 -estradiol 17 D-glucuronide ; E217 G ; 16 18 ; Knock-out mice lacking mrp1 have an impaired response to a leukotriene-mediated inflammatory stimulus 24 ; . In addition, mrp1 has been shown to regulate dendritic cell migration to lymph nodes by effluxing LTC4 25 ; . Whether E217 G is a physiological substrate is not yet known, but plasma membrane vesicles enriched in MRP1 directly transport this cholestatic estrogen conjugate with a Km of 18, 19, 26 ; . Despite the very broad substrate specificity of MRP1 and the relatively high level of primary structure conservation with mrp1 87% identity ; , the murine and human proteins display some striking functional differences 26, 27 ; . Although mrp1. The Faculty of Arts Computing Plan directs expenditures of approximately million towards academic technology equipment and services. The plan has four principal themes: implementation of the second phase of the Computer Renewal Program for faculty members; development and implementation of Teaching Enhanced Learning TEL ; curriculum initiatives; renewal of computing facilities in undergraduate labs; and renewal of computing equipment for administrative staff. Under the Computer Renewal Program, 150 computers were distributed to faculty members in 2002-2003; a further 120 computers will be distributed in year three of the plan. Some 15 pilot projects in TEL have been developed in the past three years; over 35 courses have been developed using WebCT. Computing lab capacity in support of the ITEC Program has been expanded with the addition of 30 seats in the Gauss lab.
Methods: The results of 609 cytologic bone marrow evaluations and the medical records of 34 dogs 5.6% of samples examined ; diagnosed with bone marrow necrosis were reviewed. Results: Among 34 dogs with bone marrow necrosis, nine had no identifiable cause while 25 had associated disease or drug administration. All dogs with idiopathic bone marrow necrosis had myelofibrosis and anemia, three also had neutropenia, and three also had thrombocytopenia. Of the 25 others, 14 56% ; had anemia, 14 56% ; had neutropenia, and 18 72% ; had thrombocytopenia. Ten 40% ; had myelofibrosis. Diseases associated with bone marrow necrosis were primarily sepsis, lymphosarcoma, and systemic lupus erythematosus. Drug administration associated with bone marrow necrosis included chemotherapeutics cyclophosphamide or vincristine ; , colchicine, phenobarbital, carprofen, metronidazole, fenbendazole, and mitotane.
One hundred and ninety six of the 309 patients 63.4% ; finally evaluated achieved remission of Graves' disease. There was no significant difference in relapse rates between the two groups. Thirty five and nine tenths percent confidence interval 28.3-43.6 ; of patients treated with 10 mg and 37.2% confidence interval 29.6-44.8 ; of patients treated with 40 mg MM1 had recurrences. There was also no difference in the length of the time interval between stopping treatment and relapse; this occurred at 15 months in 32 29 patients, at 18 months in 11 15, and at 24 months in 12 14 patients. The data was also analyzed by the life-table method, without any additional result. None of the following factors examined by Cox' proportional hazards model was significantly predictive of relapse: Age, sex, goiter size and nodularity, presenceof eye signs, heart rate, and therapeutic index at the time of starting treatment ; . On an intention-to-treat basis, 98 of 251 39% ; patients in the 10 mg group and 98 of 258 38% ; in the 40 mg group achieved remission and vinorelbine.

35. MEDULLOB LASTOMAS WITH EXTENSIVE POST-THERAPY NEURONAL MATURATIO N X. Cai 1 , M. Mafra 2 , R.E. Schmidt 1 , B.W. Scheithauer3 , and A. Perry 1 . Washington University School of Medicine, St. Louis, MO 1 , Hospital S. Jose, Lisboa, Portugal 2 , Mayo Clinic, Rochester, MN 3 We hereby report two cases of classical medulloblastoma, which underwent extensive therapy-associated neuronal maturation. The first patient is a 20-month-old boy who presented at 3 months of age with hydrocephalus secondary to a 5-cm tumor in the cerebellar vermis. He underwent a gross total resection of a desmoplastic medulloblastoma with neuroblastic features. No mature elements were identified. Despite adjuvant chemotherapy with cytoxan, vincristine, cisplastin, and VP-16, he developed a 1.5-cm recurrence 6 months later. Sections from the subtotally resected tumor demonstrated exclusively mature neuronal elements, ranging from neurocytes to ganglion cells. Four months later, a second recurrence was resected, this time demonstrating classic medulloblastoma morphology. The patient was subsequently treated with radiation therapy and is currently stable with evidence of tumor shrinkage and calcification. The second patient presented at age 3 with a midline cerebellar medulloblastoma and was treated with subtotal resection, radiation therapy and chemotherapy vincristine and CCNU plus intrathecal methotrexate ; . Although the tumor remained radiographically stable, a second resection was performed 8 years later to alleviate hydrocephalus. Histology revealed predominantly small mature neurons with scattered ganglion cells and extensive calcification. No adjuvant therapy was given and the patient is alive and well at last followup. The mature neuronal neoplasms from both patients demonstrated negligible proliferative indices and stained appropriately with neuronal immunohistochemical markers. The smaller neuronal population resembled those of central neurocytoma and the recently described entity, medullocytoma. Analogous to peripheral neuroblastoma, our cases suggest that adjuvant therapy can induce extensive or complete neuronal maturation in medulloblastoma. Additional cases must be studied to determine the prognostic significance of this rare phenomenon and viracept.

Histology Histological analysis showed that the ileum from sham mice had the normal architecture of the intestinal epithelium and wall, while thermal injury induced severe edema and sloughing of the villous tips, as well as infiltration of inflammator y cells into the mucosa Figure 1 ; . Semi-quantitative analysis of histological samples of ileum and jejunum showed that granulocyte infiltration in the burned mice was significantly increased compared to that in the sham group. Administration of CORM-2 8 mg kg, i.v. ; , significantly decreased granulocyte infiltration. However, CORM-2 did not improve the hydropic degeneration induced by thermal injury in either the ileum or jejunum Table 2 ; . Effect of CORM-2 on MPO activity in small intestine of thermally injured mice To determine whether the burn-induced increase in polymorphonuclear neutrophil PMN ; accumulation in the small intestine was effectively prevented by CORM-2. Effective clinical use in a very short period of time 4, 11, 30 ; . The clinical efficacy of this relatively new antibiotic in chemotherapeutic management of a variety of neoplastic conditions in man has been documented by a number of recent publications 10, 11, 21, ; . Observations from the present study and those reported earlier by other workers suggest that BLM acts by binding to nuclear DNA, causing single-strand scission and in turn inhibiting DNA synthesis. BLM, like neocarzinostatin, another polypeptide antibiotic 12 ; , causes chromatid breaks both in vitro and in vivo 3, 18, 19, ; .3 Observations from cytological studies, both with light and electron microscopy, show that BLM causes extensive altera tions in the nuclear morphology, especially in the distribution pattern of chromatin 16, 17 ; . The presence of hyaline-appear ing nuclei, which in electron micrographs show an absence of electron-dense chromatin clumps, is a regular feature of cells exposed to BLM. These nuclei occupy unusually large portions of the cytoplasm and have extensive foldings and inpocketings of the nuclear membrane. In cells exposed to lower concentrations of BLM or for shorter duration, nucleoli are unusually large. Although the initial enlargement of nucleoli is followed by some shrinking and segregation of nucleolar components, BLM does not cause extensive segregation of the nucleolar components or "capping, " as seen in cells exposed to actinomycin D 20 ; . The presence of membrane-bound oblong structures Fig. 6 ; in some of the L-cells exposed to BLM is an enigma to us. These structures are consistently seen in BLM-treated L-cells, but they bear no resemblance to proteinaceous crystals induced by vinblastine and vincristine in cultured cells 2, 14 ; . BLM, as such, is completely soluble and stable in aqueous solutions or in tissue culture media, and no crystalline residues are seen in these solutions. It is possible that the presence of these structures in L-cells was incidental and not drug related, inasmuch as similar structures were not found in other cell types exposed to BLM. Evidence from our time-lapse and election microscopic study shows that, although BLM inhibits cell multiplication, it does not affect the mitotic apparatus or the process of division itself. A small number of cells that enter mitosis in the presence of the drug, or which are exposed to lower concentrations of BLM, develop normal spindle formation of microtubules, which appear unaltered in electron micrographs. There is no effect on cleavage furrow or the subsequent migration of the daughter cells away from each other. In this regard, BLM differs from mitosis-arresting chemotherapeutic drugs that affect the spindle microtubules; e.g., vinblastine, vincristine 9, 13 ; , or drugs like cytochalasin which affect the subsequent events of cell division, such as the migrations of the daughter cells 5, 15 ; . BLM is selectively concentrated in the skin and lungs, and thus is of greater efficacy in treating skin carcinomas, etc. 4, 11, 21 ; . A differential lethality of BLM depending on cell type or strain has been reported by other workers 1, 27 ; and is and viread.

If it is assumed that the development of transfer cells and the induction of root reduction activity are controlled by a shared regulatory system, a parallel repression of the responses by increasing iron concentrations is to be expected. To test this assumption, both reactions were examined at various concentrations of external iron in the growth medium. To allow for a correlation of the amplitude of the responses with the concentration of external iron under consideration of changes in the activity of soluble iron species, such as displacement of Fe3 from EDTA as the ligand-held ion by divalent metal ions, the concentration of ferric iron bound to EDTA was calculated using the Geochem PC software program Parker et al., 1995 ; . We chose roots from the tomato wild type as the experimental system because the percentage of transfer cells is sufficient to recognize and vistaril. And applied slowly into large veins in order to prevent phlebitis, until a switch from intravenous to oral therapy is possible. I.e Irish Gaelic ; "sithech, " meaning wolf."195 Again, the wolf was the familiar hunting form of both the Cailleach Bheur Winter Hag ; and Mhorrigan, one-time leaders of the Daoine sidh. In 1844, local newspapers described a winter in which wolves were "very destructive in Sussex and Musquah New Brunswick ; ." By 1902, when a pair were reported seen at the Public Landing in Fredericton, they were headed for certain extinction, and the individual sidh may have passed with them. On the other hand, an account dated 1992 tells of the little people seen by the grandmother of Rosella Sampson of Grand Anse, ands this sighting would be within the current century: She was on the road home one night when she became aware of a horse being fiercely ridden by "a miniscule little man.his fingers tangled fast in the horse's mane. The horse was lathered and straining to breathe, as if he had been ridden that way for a long time." Rosella's grandmother remembered that the sidh were like the Acadian "lutins" in their interest in horses. In former times she said that men braided the manes and tails of their horses to prevent them from being "hag-ridden." To trap the tiny men, farmers sometimes balanced a bucket of oats on a half-opened door. If the intruder happened to spill the oats he would remain to pick them up one-by-one as the sidh made a fetish of neatnesss. Rosella was told that the "fairies" were regarded as demons of the Devil. "Since they were lost souls, not to be saved on the day of judgement, they made everyone's life miserable, since they had nothing to lose." The description of the sidh as "demons" is common in local folklore and suggests some earlier knowledge of the constitution of this spirit. The Greecian "daemons" corresponded best with the creature which the Gaels knew as the "befind" and which the English called the "cowalker", the spirit finally converted into the Christian "guardian angel." It is known that the befind were conscripted to serve men from the ranks of the Daoine sidh. As for demons, they were defined as "guardian divinities of men, holding a place between men and the gods." It was once held although not universally ; that men were born with two daemons, one evil and one good. Others believed that the daemon was at once good and evil, the two forces emerging variously according to the will of the human. Thus ancient literature speaks of the "daemon of Socrates" as being a directing force in his life and vivelle. Table 2.

EFS in protocol 89-C-41 was 92% at 2 years and survival.2 In both studies, adults with SNCL small non-cleaved cell lymphoma ; had a similar prognosis with children, but result obtained with protocol 89-C-41 appear to be significantly better for all patients, particularly those with bone marrow and CNS involvement. According to this result, protocol 89-C-41 for high risk patient had been chosen to treat our patient. The patient was finished first cycle called CODOX-M without too much bone marrow suppression relatively high WBC, ANC, Hgb, and Hct ; . After the cycle, LDH lever was getting lower as well. Thus, we could conclude that treatment was appropriate for our patient and vinorelbine!
