Hypercoagulability develops after surgery for esophageal carcinoma, and it related closely to postoperative complications. This study evaluated the effects of the synthetic proteinase inhibitor, Cabexate Mesilate (FOY), on this hypercoagulability. The subjects used were 25 patients with a mean age of 63 who had undergone surgery for esophageal carcinoma. Of these, eight patients (test group) received FOY (2,000 mg/day) for three to 23 days after surgery, but 17 (control group) did not. In the test group, FOY controlled aggregation and release of the platelets and minimized their exhaustion. FOY almost completely checked the abnormal increase in thrombin activity which might trigger the hypercoagulability. Also, FOY suppressed the fibrinolytic activity slightly. These results indicate that FOY is effective in controlling hypercoagulability after surgery for esophageal carcinoma and in suppressing activity of the proteinases that cause both blood coagulation and fibrinolysis. 相似文献

A case of polycythemia vera complicated by chronic renal failure under maintenance hemodialysis requiring parathyroidectory
(PTH) for secondary hyperparathyroidism (2° HPT) is reported.
A 62 year old female presented with 75000 white blood cells (WBC)/μl, 703×104 red blood cells (RBC)/μl, 23×104 platelets (PLT)/μl, hyperuricemia and hypertension in 1970 and the diagnosis of polycythemia vera was made. Hemodialysis
was started in October 1974 for chronic renal failure. Blood cells in peripheral blood rapidly decreased in number after the
beginning of dialysis, reaching the level of 10000∼20000 WBC/μl, and 150∼250×104RBC/μl. In August 1988, marked bone resorption in X-ray picture and high serum alkaline phosphatase and parathyroid hormone
(PTH) noted along with 17400 WBC/μl, 370×104RBC/μl and 35.9×104PLT/μl.
After subtotal PTX removing 3.21g parathyroid gland, serum PTH rapidly fell. At 3 months after PTX, WBC rose to 23600/μl,
RBC 372×104/μl and PLT 94.0×104/μl. At 6 months, WBC was to 31000/μl, RBC 429×104/μl and PLT 78.0×104/μl, suggesting an inhibitory action of PTH on not only RBC, but also WBC and PLT. 相似文献

Nephron Sparing Surgery for De Novo Renal Cell Carcinoma in an Allograft Kidney: A Case Report 总被引:1,自引:0,他引:1

De novo renal cell carcinoma in a renal allograft is rare and has special implications in renal transplant recipients. We describe a patient with a renal allograft who developed a de novo renal cell carcinoma in the functioning renal allograft 258 months after transplantation. The patient underwent enucleation of the tumor because preoperative MRI showed it was well-encapsulated. A DNA banding study showed that the tumor originated from the donor. Indications for conservative renal surgery in renal cell carcinoma have been increasing. Accordingly, 1 option in the treatment of de novo renal cell carcinoma in a functioning renal allograft is enucleation as a method of nephron sparing surgery. 相似文献

We present a 44-year-old woman in whom a bronchialto-coronary artery communication via the conus branch was discovered after distal bronchial artery embolization with gelatin sponge for hemoptysis. If this bronchial-to-coronary artery anastomosis, not visible prior to embolization, had been inadvertently embolized, the patient could have developed a myocardial infarction. To reduce the likelihood of a serious complication, the possibility of this anastomosis should be kept in mind and angiography should be repeated before attempting proximal bronchial artery embolization. 相似文献

In order to evaluate the quality of life (QOL) in hypertensive outpatients, we selected 78 patients with hypertension of various degrees of severity (WHO Classification I: 29 cases, II: 15, III: 34), 59 not ill healthy persons (N1) and 22 normotensive outpatients (N2) aged at 50 years and over, using the self-completed questionnaire (QUIK) which we developed. QUIK covers four domains including physical functioning (20 questions), emotional adjustment (10), interpersonal relationships (10) and attitudes toward life (10) totaling 50 questions. In this study the internal consistency of QUIK was alpha = 0.95 by the Kuder-Richardson formula 20 and it's repeatability was r = 0.89 by the Spearman-Brown formula. The QOL in hypertensive outpatients was definitely worse in terms of total score (N1 5.1 +/- 4.4 vs WHO II 9.3 +/- 7.2 and III 12.1 +/- 5.6, p < 0.05), for physical functioning (N1 2.5 +/- 2.1 vs WHO I 3.7 +/- 2.8, II 4.7 +/- 3.8, III 5.4 +/- 2.8 p < 0.05), for emotional adjustment (N1 1.2 +/- 1.4 vs WHO III 2.3 +/- 1.7, p < 0.01), for interpersonal relationships (N1 0.8 +/- 1.3 vs WHO III 1.6 +/- 1.5, p < 0.01) and for attitudes toward life (N1 0.7 +/- 1.2 vs WHO III 2.7 +/- 2.0 p < 0.01). The total QUIK score increased according to the severity of symptoms (WHO I 5.8 +/- 4.4, WHO II 9.3 +/- 7.2 and WHO III 12.1 +/- 5.6), respectively. The total score of WHO I was significantly lower compared with that of WHO III (p < 0.01).(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献

The effects of 12 essential oils, popularly used as antifungal treatments in aromatherapy, on growth of Candida albicans were investigated. Mycelial growth of C. albicans, which is known to give the fungus the capacity to invade mucosal tissues, was inhibited in the medium containing 100 micro g/ml of the oils: lemongrass (Cymbopogon citratus), thyme (Thymus vulgaris), patchouli (Pogostemon cablin) and cedarwood (Cedrus atlantica). Not only lemongrass oil but also citral, a major component of lemongrass oil (80%), in the range of 25 and 200 micro g/ml inhibited the mycelial growth but allowed yeast-form growth. More than 200 micro g/ml of citral clearly inhibited both mycelial and yeast-form growth of C. albicans. These results provide experimental evidence suggesting the potential value of lemongrass oil for the treatment of oral or vaginal candidiasis. 相似文献
