Treatment of 26 women with tubal infertility was attempted using intrauterine capsules loaded with oocytes and spermatozoa. The stimulation protocol was as used for in vitro fertilization and embryo transfer and consisted of short-term use of Buserelin, human menopausal gonadotropin, and human chorionic gonadotropin. Oocytes were collected by ultrasonically guided transvaginal aspiration, and spermatozoa were prepared by swim-up technique. The gametes were placed in agar capsules 4 hr after oocyte collection, and the capsules were introduced to the uterine fundus using an insertion tube and piston from an intrauterine device. Six complete capsules and parts of two other capsules were expelled. None of the women became pregnant, compared with a pregnancy rate of 21% per aspiration following in vitro fertilization and embryo transfer during the same period. 相似文献

Summary Experience with antibody-dependent, cellmediated cytotoxicity (ADCC) has shown that antibody can increase the localization and killing capacity of lymphocytes. We tested the possibility of improving the activity of lymphokine-activated killer cells (LAK) on human tumor using the subrenal capsule assay in nude mice. The tumors were first grown in the renal capsule space and the effector cells injected later. In the model experiment we used M21 melanoma and monoclonal antibody against melanoma-associated antigen GD3. This antibody increases the tumor inhibitory activity of LAK cells from healthy donors in comparison to LAK alone. We have been able to prove the clinical relevance of such an approach. Tumor bioptic material from five tumor patients was tested with various monoclonal antibodies, following which the highly reactive antibodies were selected and incubated with the patient's LAK cells. Such pretreated LAK cells have a high growth-inhibitory effect on autologous tumor growing in the renal capsule space of the test mice. 相似文献

Soft tissue sarcomas make up a heterogenous group of rate malignant tumors originating from mesodermal tissues. Although there have been several improvements in diagnostic methods, staging, and treatment over the past few years, the prognosis of head and neck sarcomas remains worse than those sited at the trunk or extremities. The purpose of this retrospective study was to report the survival results of 128 consecutive patients with soft tissue sarcomas of the head and neck treated from 1953 to 1985. Of the 93 patients submitted to surgical resection, the procedure was considered radical in 67 patients. Of the operated gruop, 46 patients (49.5%) developed recurrence of disease. Thirty-two patients underwent further treatment (surgery, radiotherapy, or chemotherapy), and 14 patients were salvaged, giving the ultimate result of 65.6% disease control rate in the operated group. The univariate survival analysis showed no statistical difference (P > 0.05) according to age, race, sex, and site or histologic type of the tumor. Radicality of surgery was an important prognostic factor affecting survival (P = 0.0014 for disease-free interval and P = 0.0183 for overall survival). The multivariate analysis showed that the radicality of surgery and tumor histology were independent prognostic factors affecting recurrence. The same variables and age group were related to the risk of death. Every effort must be made to make an early diagnosis and a radical surgical resection of these tumors must be tried (except for embryonal rhabdomyosarcoma), because it offers the best chance for cure. © 1994 Wiley-Liss, Inc. 相似文献

Summary Postcartilaginous development of the otic capsule was studied in undecalcified histological material from rabbits following sequential fluorochromic time labeling of mineralizing tissues, using combined microradiography, fluorescence microscopy and osteoid staining. Early fetal bone formation was monitored by labeling of the experimental animals in utero. In contrast to the normal pattern of drift movements displayed by long bones and extracapsular cranial bone, capsular bone inside a zone immediately surrounding the perilymphatic space developed as a separate functional unit in which growth and modeling was absent. Bone tissue behavior appeared to depend on its spatial relation to the membranous labyrinth rather than histological characteristics. These findings suggest the role of inner ear tissues as a functional matrix in control of capsular bone dynamics beyond fetal life. 相似文献

本研究观察了中药复方愈心痛胶囊消化道给药对实验性急性心肌缺血犬血浆内皮素(ET)和血清一氧化氮(NO)水平及肌酸磷酸激酶(CPK)活性的影响。结果显示:在犬急性心肌缺血过程中血清CPK活性和血浆ET水平均显著增高,血清NO水平下降。愈心痛胶囊两个剂量组均可明显抑制实验性犬心肌损伤时CPK的溢出和血浆ET的过量释放,同时促进NO的生成和释放,与盐水对照组比较差异显著(P<0.05~0.001),从而保护心肌免受缺血性损伤,其作用效果与剂量呈正相关。 相似文献
