The authors studied the effectiveness of out-patient treatment by Moditen-Deppt of 128 schizophrenic patients. A comparison of the previous remissions appearing during usual pharmacotherapy and remissions seen during Moditen-Depot treatment depicted statistically significant differences, indicating a distinct prevention of exacerbations due to this preparation, an increase in the duration and improved quality of remissions. Such improved remissions were expressed in lesser severity, in a decrease of psychopathological disturbances, changes qualified as a "mollification of a defect" and an improvement of some socio-clinical indices.  相似文献

The ETV6 (TEL) locus at chromosome band 12p 13 is a major site of translocations in acute leukemia, particularly in childhood acute lymphoblastic leukemia (ALL). In cases with translocations involving ETV6, the normal ETV6 allele is often deleted. In addition, loss of heterozygosity of ETV6 is frequently observed in childhood'ALL. Thus, it has been suggested that ETV6 may have an anti-oncogenic role to play, in addition to its oncogenic role. We have described an unusual case of ALL in which ETV6 is found fused to the ABL gene; ABL is normally activated by fusion to the BCR gene in the 9:22 translocation. We expanded the primary cells from this ETV6/ABL rearranged case of ALL in SCID animals and analyzed them for expression of both ETV6/ABL and the normal ETV6 mRNA. We found that both the rearranged and normal ETV6 mRNAs are expressed in the expanded cell population. Furthermore, sequence analysis of the ETV6 PCR product revealed no point mutations which would influence the amino acid sequence. Thus, deletion of the second ETV6 allele is not necessary for the transformation to leukemia by ETV6/ABL.  相似文献

An algorithm and a personal computer program for automatic distinguishing between EEC records containing evoked and no potentials, based on the detected invariants reflecting experts' experience in evoked potential analysis have been developed. The efficiency of the programme (its high accuracy and speed, low volume) has been demonstrated in the system for automatic determination of the hearing level by long-latent evoked potentials. It is easily modifiable to identify evoked potentials from other modalities (visual, somatosensory ones) in the systems using the traditional and/or up-to-date computerized EEC equipment.  相似文献

A significant decrease in the total number of mitotically dividing cells (per 1 crypt), especially in the lower portions of the intestine, was observed in rats with avitaminosis A. The levelling of differences in the number of goblet cells in the upper and lower portions of the intestine was also recorded in the animals with avitaminosis A. The investigations conducted have evidenced retinol participation in differentiation and, to a lesser extent, in proliferation of epitheliocytes of the rat small intestine.  相似文献

A system is described for an automatic analysis and recognition of a fresh and reference histologic material. The system includes a microscope, TV camera and personal computer. The system proved applicable in identification of two tumor types: astrocytomas and oligodendrogliomas. The system can be used in pathology, histology, embryology, cytology, histochemistry, clinical laboratory microscopy and in borderline fields.  相似文献

1 The professional nurse who practices within the field of addictions is in an ideal position to serve as an educational conduit and catalyst for promoting understanding of the addictive process. 2 Historically, the use of analogy as a teaching device can be seen in the readings of the Bible to as far back as Plato. 3 The client's level of functioning must be assessed by the professional nurse so that any educational approach or intervention will be designed to meet the appropriate level of the client.  相似文献

The authors report a clinico-morphological traits in Ray's syndrome which occurred in 10 children with acute respiratory disorders. The prevalent symptoms were encephalopathy with fatty dystrophy of the internal organs and mainly of the liver. Literature data concerning the clinical picture, diagnosis and treatment of this disorder are discussed.  相似文献
