| [clinical evaluation of renal autotransplantation in renal vascular hypertension]. | from 1976 to 1984, 22 cases of renal vascular hypertension were treated with renal autotransplantation. 20 cases have been followed up for 3-11 years, 17 cases of them over 5 years. the results showed that 14 cases were cured, 5 cases relieved, 1 cases ineffective. 19 cases of these patients suffered from large arteritis, 3 cases from atherosclerosis. the clinical efficacy of the former was better than the later. our results suggest that the clinical efficacy has nothing to do with the course of ... | 2009 | 2673688 |
| heart tumors specifically induced in young avian embryos by the v-myc oncogene. | to determine if expression of the v-myc oncogene had any effect during ontogeny, we injected avian myelocytomatosis virus strain mc29 into avian embryos at various stages of development. the injection of mc29 at embryonic day 2 (e2) or 3 (e3) caused, about 10 days later, rhabdomyosarcomas of the heart and, in some cases, skin muscle hypertrophy. when the injection was performed at e4 or e5, the number of heart tumors declined, whereas the number of skin muscle tumors increased significantly. the ... | 2009 | 2825173 |
| age-related changes of splenic t cells in mice--a flow cytometric analysis. | splenic t cells of c57bl/6 mice, ranging in age from newborn to 24 months old, were examined by two-colour flow cytometry using monoclonal antibodies (moabs) to thy-1, lyt-1, lyt-2 and l3t4. thy-1+ cells in the spleen increased gradually after the birth, and reached a plateau around at 3 months of age, but did not show a significant age-related decline even at 24 months of age. lyt subpopulations of t cells (lyt-1+2+, lyt-1+2-, lyt-1-2+) showed a proportional increase until 1 month of age, but t ... | 2009 | 2891881 |

| the use of banked femoral head bone allograft in spinal surgery. | a safe, simple, and inexpensive method of harvesting femoral head allograft bone and storing it in a mechanical deep-freeze is discussed. this banked bone has been used in 39 patients for posterior spinal fusions. the allograft bone was used only where insufficient autograft bone could be harvested, where the autograft bone was regarded as inferior in quality or when harvesting autograft bone would have been hazardous to the patient. the allograft bone was found to be very reliable in helping to ... | 2009 | 2669169 |

| an evaluation of techniques used for the detection of anthelmintic resistance in nematode parasites of domestic livestock. | in vitro and in vivo techniques used for the detection of anthelmintic resistance are reviewed in terms of their versatility, reliability, accuracy, cost and simplicity. the faecal egg count reduction test is considered the most suitable for field screening of resistance but the larval development assay is likely to prove a valuable adjunct in such investigations. other in vitro techniques, such as egg hatch tests, larval motility and tubulin binding assays are recommended as suitable only for r ... | 2009 | 2698534 |

| [endodontics: mechanical or manual methods? preparation and cleaning of root canals]. | neither with mechanical nor with manual methods is it possible to achieve a preparation of the entire root canal in all wall areas. a reasonable combination of hand instruments with engine-driven, sonic or ultrasonic units certainly has advantages in preparing, cleaning and irrigating the root canal. what is more important than the question of mechanical or manual preparation of root canals is that the operator should work meticulously and have a thorough knowledge of the root canal anatomy. whi ... | 2009 | 2698341 |
| nsaid-induced gastropathy in the elderly: understanding and avoidance. | nonsteroidal anti-inflammatory drugs (nsaids) are a significant cause of gastric mucosal injury and bleeding, particularly in elderly patients. the mechanism of this injury appears to be, at least in part, a disruption of normal cytoprotective mechanisms by the inhibition of prostaglandin production. acute injury results from the local effect of some drugs and may resolve with time. chronic injury may occur with any nsaid and may often be asymptomatic until a complication occurs. treatment of ei ... | 2009 | 2666269 |
| interpreting the carboxyhaemoglobin concentration in fetal cord blood. | we calculated the fetal-to-maternal carboxyhaemoglobin concentration ratio in 19 mother-infant pairs at the time of term delivery. mothers, who had a less than 10% drop in their carboxyhaemoglobin concentration during labour, had an average ratio of 1.40 +/- 0.19. for mothers whose carboxyhaemoglobin concentrations dropped by 10% or more during labour, the average fetal-to-maternal carboxyhaemoglobin concentration ratio was 1.83 +/- 0.48. there was a strong correlation (r = 0.82) between the per ... | 2009 | 2778293 |
| clinical features and management of amebic liver abscess. experience from 29 patients. | 29 patients with amebic liver abscess were evaluated in a study to examine clinical picture, laboratory data, epidemiology, radiologic methods, and therapy. since the clinical picture was unspecific a considerable amount of misdiagnoses occurred, and often originated from pulmonary symptoms. to establish diagnosis one should rely on the triad with positive amebic serology, intrahepatic scanning defects, and clinical picture with fever, right upper quadrant pain, and hepatomegaly. nearly all pati ... | 2009 | 2657204 |
| management of subarachnoid hemorrhage in the critical care unit. | subarachnoid hemorrhage from a ruptured intracranial saccular aneurysm is associated with a high rate of morbidity and mortality. most complications occur two to three weeks after the initial hemorrhage. the key to minimizing morbidity and mortality is early and aggressive intensive-care management. the cleveland clinic neurosurgical intensive care unit approach is reviewed. | 2009 | 2691116 |
| merkel cell tumour of the face successfully treated with radical radiotherapy. | a case of merkel cell tumour of the face and its dramatic response to a course of radical radiotherapy is presented below. the patient has been free of recurrence for 18 months and has suffered minimal side-effects from the treatment. this suggests that radical radiotherapy, as opposed to the standard wide excision, may be the preferred first-line treatment for at least some of these rare, but highly malignant tumours. | 2009 | 3345856 |
| [adenosquamous carcinoma and squamous cell carcinoma of the liver: a resected case and three autopsied cases]. | a resected case and an autopsied case of an adenosquamous carcinoma and two autopsied cases of a squamous cell carcinoma of the liver are presented. with regard to the first case, a 58-year-old male underwent an operation, based on the diagnosis of a hypovascular hepatoma or a cholangioma. the resected material showed a nodular whitish gray tumor at the s4 region which histologically proved to be an adenosquamous carcinoma. in the two autopsied cases, found was a huge, grayish necrotic mass at t ... | 2009 | 2681878 |

| transitional cell carcinoma of the renal pelvis and ureter. | in a retrospective study of 185 patients with transitional cell carcinoma of the renal pelvis and ureter, of whom 127 were treated by total nephroureterectomy and 58 by conservative resection, the survival of those with superficial well differentiated tumours was greater than 90% in each group. when urothelium was left behind after conservative resection, there was a 22% rate of recurrence on the same side but this almost only occurred when the original tumour had been multifocal. post-operative ... | 2009 | 2702397 |
