A total of 26 lung cancer cases accompanied by pleural dissemination were resected between June 1977 and June 1988. Of these 16 cases were male and 10 cases were female. Their age was 34-78, and the average age was 56.7 years. The histologic type was adenocarcinoma in 23 cases, 1 was large cell carcinoma, 1 was combined adenosquamous cell carcinoma, and 1 was combined adeno-small cell carcinoma. Of these 23 adenocarcinoma cases, 15 were well differentiated, 7 were moderately differentiated, and 1 was poorly differentiated. There was no correlation between tumor size and pleural dissemination. Pleural effusion was observed in 8, 5 had bloody effusion and the other 3 had yellow effusion. Exact preoperative diagnosis and evaluation of extent was very difficult in pleural dissemination cases except for the pleural effusion cases. Concerning the operation method in these cases pleuropneumonectomy was performed in 10, pleurolobectomy in 6, and lobectomy in 10. Prognosis of cases of resected pleural dissemination was very poor. The median survival time was 16 months, The 1-year survival rate was 56.3%, the 2-year survival rate was 23.2%, the 3-year survival rate was 15.4%, and the 4-year survival rate was 7.7%. There was no 5-year survivor in lung cancer cases of this group. Malignant pleural effusion cases had a poorer prognosis, with 6 of 8 cases dying within 1 year from operation. No remarkable therapeutic effects were achieved by adjuvant chemotherapy. In the single case of preoperative hyperthermia, histological therapeutic effect (Ef 2) was recognized. These results suggest that there is no indication of operation in malignant pleural effusion cases.(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献

We describe the clinical and imaging findings of brain stem tumours in patients with neurofibromatosis type 1 (NF1). The
NF1 patients imaged between January 1984 and January 1996 were reviewed and 25 patients were identified with a brain stem
tumour. Clinical, radiographical and pathological results were obtained by review of records and images. Brain stem tumour
identification occurred much later than the clinical diagnosis of NF1. Medullary enlargement was most frequent (68 %), followed
by pontine (52 %) and midbrain enlargement (44 %). Patients were further subdivided into those with diffuse (12 patients)
and those with focal (13 patients) tumours. Treatment for hydrocephalus was required in 67 % of the first group and only 15
% of the second group. Surgery was performed in four patients and revealed fibrillary astrocytomas, one of which progressed
to an anaplastic astrocytoma. In 40 % of patients both brain stem and optic pathway tumours were present. The biological behaviour
of brain stem tumours in NF1 is unknown. Diffuse tumours in the patients with NF1 appear to have a much more favourable prognosis
than patients with similar tumours without neurofibromatosis type 1.

研究消炎痛及乙胺嗪对家兔肺、脑血管和大鼠脑微动脉缺氧反应的影响。发现吸入10%氧使家兔肺血管阻力(PVR)增加,脑血管阻力(CVR)降低,大鼠脑微动脉扩张。用消炎痛明显增强家兔缺氧性肺、脑血管反应。△PVR%由用药前26.6±16.7%增至44.2±7.7%;△CVR%则由一12.9±4.5%减至-30.7±4.7%;大鼠微动脉直径增大率(△D%)由用药前28.2±2.0%增至41.3±5.8%;用乙胺嗪则使缺氧时△PVR%由 84.6±18.1%降至 23.8±8.5%;△CVR%由-16.7±4.5%变为 6.9±2.8%;△D%由 29.7±5.8%减至 25.6±5.0%。结果表明前列腺素在缺氧性肺血管收缩反应及脑血管扩张反应中起调节作用,而白三烯则在缺氧性肺血管收缩反应中起介导作用。 相似文献

Retrograde air insufflation in MRI: A technical note 总被引:2,自引:0,他引:2
Retrograde air insufflation was employed to distend the colon and the ileum in 18 patients and five volunteers for magnetic resonance examination. Good and moderate marking of the ileum was obtained in 18 cases. The colon was nearly completely distended in every case. Intraluminal tumor, mural thickening, and extraluminal lesion were outlined by intraluminal air and surrounding air-distended bowel. This study shows that retrograde air insufflation is a useful method to mark the colon and most parts of the ileum. 相似文献

Role of endothelin in the pathogenesis of hypertension in spontaneously hypertensive and 2 kidneys 1 clip rats. 总被引:1,自引:0,他引:1
The plasma endothelin (ET) level in spontaneously hypertensive rats (SHR) and 2K1C hypertension animal models and its vasoconstrictive effect on renal and tail arteries were studied. The results demonstrated that there was no difference in plasma ET level between the hypertensive groups SHR, 2K1C, normotensive control groups Wistar Kyot (WKY) and Sprague Dawley (SD), while the vasoconstrictive effect of ET in SHR was more dominant than in WKY. The EC50 of the renal and tail arteries in SHR (0.8912 +/- 0.1662 x 10(-8) M, 0.6103 +/- 0.0878 x 10(-8) M) was apparently lower than that in WKY (1.77 +/- 0.2991 x 10(-8) M, 1.2267 +/- 0.2502 x 10(-8) M, P less than 0.05), but no difference was found in 2K1C and SD rats. The four groups of animals exhibited no difference of such effects as response to norepine-phrine (NA). The findings suggested that the increased arteriole sensitivity to ET be an important factor in the pathogenesis of hypertension in SHR.

Serum LPO content was measured by means of TBA in 41 patients suffering from craniocerebral injury in present study. The relationships between OFR and progressing course of craniocerebral injury, level of LPO and patient condition of an injury and prognosis were analysed. Results showed that serum LPO increased obviously in 24 hours after injury. The more severe the condition of an injury was, the higher the serum LPO content was, the worse prognosis would be. Serum LPO content increased statistically in group of death in 24 to 72 hours after injury, while it didn't change significantly in group of survival. The author suggest that the reaction of OFR enhanced after craniocerebral injury, and which was an important factor giving rise to secondary brain injury. Measurement of serum LPO content plays an important role in estimating the patients condition of injury and their prognosis. 相似文献
