Abstract
The zebrafish gastrointestinal system matures in a manner akin to higher vertebrates. We describe nine mutations that perturb development of these organs. Normally, by the fourth day postfertilization the digestive organs are formed, the epithelial cells of the intestine are polarized and express digestive enzymes, the hepatocytes secrete bile, and the pancreatic islets and acini generate immunoreactive insulin and carboxypeptidase A, respectively. Seven mutations cause arrest of intestinal epithelial development after formation of the tube but before cell polarization is completed. These perturb different regions of the intestine. Six preferentially affect foregut, and one the hindgut. In one of the foregut mutations the esophagus does not form. Two mutations cause hepatic degeneration. The pancreas is affected in four mutants, all of which also perturb anterior intestine. The pancreatic exocrine cells are selectively affected in these four mutations. Exocrine precursor cells appear, as identified by GATA-5 expression, but do not differentiate and acini do not form. The pancreatic islets are spared, and endocrine cells mature and synthesize insulin. These gastrointestinal mutations may be informative with regard to patterning and crucial lineage decisions during organogenesis, and may be relevant to diabetes, congenital dysmorphogenesis and disorders of cell proliferation.

Abstract
In a large scale screen for genetic defects in zebrafish embryogenesis we identified mutations affecting several aspects of ear development, including: specification of the otic placode, growth of the otic vesicle (otocyst), otolith formation, morphogenesis of the semicircular canals and differentiation of the otic capsule. Here we report initial phenotypic and genetic characterization of 20 of these mutations defining 13 independent loci. Embryos mutant at the quadro locus display abnormal specification of the otic placode. As revealed by dlx-3 expression, the otic field in the mutant embryos is smaller or split into two fields. At later stages of development the ear of quadro mutants is frequently divided into two smaller, incomplete units. Four loci affect ear shape shortly after formation of the otic vesicle. All of them also display abnormal brain morphology. Mutations in five loci result in the absence of otolith formation; two of these also produce changes of ear morphology. Two loci, little richard and golas, affect morphology of the otic vesicle shortly before formation of the semicircular canals. In both cases the morphogenesis of the semicircular canals is disrupted. Finally, the antytalent locus is involved in late expansion of the ear structure. Analysis of mutations presented here will strengthen our understanding of vertebrate ear morphogenesis and provide novel entry points to its genetic analysis.

Abstract
We would like to introduce intracavitary brachytherapy using double rod-shaped applicators. The women who are treated with this method are evaluated in III FIGO stage and the patients in stage I and II who could not undergo the operation. This method allows to distribute equally the dose in whole uterus, insertion of the applicators is not difficult. The brachytherapy treatment is well tolerated.

Abstract
The results of allogenic bone marrow transplantation (allo-BMT) in 26 children with ALL treated with the same initial- and relapse-BFM-protocols, but transplanted in different centers (Poznań, Wroclaw, Hannover) after conditioning with two different regimens have been compared. Ten children (6 in Poznań, 4 in Wroclaw) were conditioned for BMT with busulfan and cyclophosphamide when fractionated TBI (FTBI) was not available there. Sixteen children obtained FTBI and etoposide (11 in Hannover, where in children with ALL exclusively chemoradioconditioning regimen has been employed, and 5 in Poznań). It has been found, that the chemoconditioning procedure was probably less effective (5-year EFS 18%) than the regimen with FTBI (7-year EFS 60%). Therefore, TBI seems to be at this point still mandatory in pediatric ALL patients, unless combinations of chemotherapeutic drugs might be able to substitute the radiation in the future.

Abstract
A method of correcting the output dose rate of the radiotherapeutic cobald units is presented. This method links measurements values with the decay formula for increasing the accuracy of output dose rate determining. The least squares method has been applied to mathematical processing of the data. Results were discussed on the record of output dose rate which had been measured since 1969.

Abstract
Mammalian genomes contain clusters of homeobox genes (Hox-C, HOX-C) which are structurally similar to the homeotic genes of the Drosophila HOM complex. One method for assessing the functional similarity of particular Drosophila HOM and mammalian Hox genes is to test the ability of Hox genes to induce homeotic phenotypes when expressed in developing Drosophila. Here we describe such functional tests using mouse HoxB9 (formerly Hox-2.5), whose closest structural relative in Drosophila is Abdominal-B. When expressed from a heat shock promoter, HoxB9 induces transformations of head towards more posterior identities in Drosophila larvae and adults. These transformations share some similarities with the phenotypic effects produced by ectopically expressed Abdominal-B, but are also similar to the transformations induced by Antennapedia and mouse HoxB6 (Hox-2.2), suggesting that HoxB9 specifies a positional identity that is intermediate between Antennapedia and Abdominal-B.

Abstract
Irradiation of cancer diseases with intracavitary applicator makes impossible visual control of applicator's position during the process of irradiation. In this paper example applicator moves during the treatment are presented and their influence to dose distribution especially in reference points is discussed. Verification of applicator's position has been made by the use of roentgen films.

Abstract
Like other homeobox genes of the Antennapedia and bithorax complexes (collectively called the HOM complex), the Drosophila Deformed (Dfd) gene has structural homologues in the Hox/HOX complexes of mouse and humans, one of which is human HOX4B (refs 3, 4). Previous experiments indicated that HOX4B protein can specifically activate the expression of the endogenous Dfd transcription unit in Drosophila embryos and larvae. We therefore asked whether HOX4B cis-regulatory elements could mimic the function of a Dfd autoregulatory element in Drosophila embryos. Here we show that a HOX4B upstream element can surprisingly provide expression in a posterior head segment of Drosophila. One possible mechanism for the axial position-specificity of the human element may involve the conservation of a Dfd-specific autoregulatory circuit in both arthropod and chordate lineages. This possibility is supported by the finding that a Drosophila Dfd autoregulatory element supplies spatially localized expression in the hindbrain of mouse embryos.

Abstract
A quick method of calculating the dose-rate distribution in irregularly shaped beams is presented. This method is partly based on the Cunningham model. The proposed modifications make it possible to avoid the scatter functions in favor of direct use of tissue-phantom ratios and field size coefficients. The problem has been evaluated for photons generated by 10 and 23 MV linacs. The calculated dose rates have been compared with measured ones, and good accuracy has been achieved.

Abstract
We are presenting a method of calculating the dose-rate distributions in partially shielded field. An attenuator was placed in central beam axis and also in an off-axis geometry. The study was made with a Co-60 radiation and with photons generated by 10 and 23 MV Linac at depths, in phantom, from 5 to 30 cm. To obtain the calculated values of dose-rates; the contributions of the three components to the total dose-rate were measured. The calculated dose-rate distributions agree well with the measured data in case of 10 MV and 23 MV radiation.

Abstract
The bovine papillomavirus (BPV) type 1 E5 gene encodes a 44-amino-acid protein that can stably transform cultured rodent cells when expressed in the absence of all other viral genes. We have previously constructed a BPV-simian virus 40 recombinant virus (Pava-1) which efficiently expresses the BPV type 1 E5 gene in infected cells (J. Settleman and D. DiMaio, Proc. Natl. Acad. Sci. USA 85:9007-9011, 1988). Within 48 h of Pava-1 infection, the vast majority of mouse C127 cells underwent a dramatic morphologic transformation which was accompanied by cell proliferation. Infection of C127 cells made quiescent by contact inhibition and serum starvation caused a great induction of cellular DNA synthesis. These morphologic and mitogenic responses were proportional to the virus multiplicity of infection. Mutational analysis indicated that the E5 gene is both necessary and sufficient for these activities. Analysis of a variety of E5 missense mutants revealed a strong correlation between their phenotypes in the acute transformation assays following infection and in the stable focus-forming assay following transfection. Most of the defective mutants expressed normal levels of E5 protein following infection, indicating that their defective phenotypes are not due to the synthesis of an unstable protein. The failure to genetically resolve these E5 activities suggests that the ability of the E5 protein to cause acute morphologic transformation and reentry into the cell cycle may be intimately related to its ability to cause stable cell transformation and that these functions are probably mediated by a single biochemical activity of the E5 protein.
