A 67-year-old man with positive serum reaction for syphilis had been followed by cardiologist for his moderate-sized saccular ascending aortic aneurysm and small-sized abdominal aortic aneurysm. Because of his transient ischemic attack probably secondary to the thrombo-embolism of the aneurysm and rapid growing of its size, surgical treatment was recommended. Resection of the saccular aneurysm with patch plasty of the ascending aorta was performed under the cardiopulmonary bypass associated with right side cerebral perfusion. At the time of operation, the mildly dilated ascending aorta and arch with multiple intimal ulceration were noted. Although his postoperative hemodynamic condition was stable, he suffered from multiple cerebral infarction, probably due to embolism migrated from the fragile aortic intima. His neurological condition was improved promptly, trivial hemi-paralysis was remained. The specimen of resected aneurysmal wall revealed syphilitic changes microscopically. We concluded that the extent of the aortic replacement with prosthetic graft should be deceived not only with its external appearance, but also with the changes of its inside. 相似文献

A rare case of jejunal carcinoma coexisting with adenoma, situated 120 cm distal to the ligament of Treitz in a 53 year old
male, is reported herein. We also review cases of adenoma and carcinoma in the jejunum and ileum from the Japanese literature,
and discuss the histogenesis of carcinoma of the jejunum and ileum. 相似文献

Abstract: The effects of pyridoxalated hemoglobin polyoxyethylene conjugate (PHP) and stroma-free hemoglobin (SFH) on vascular responsiveness to various vasoactive substances were examined in isolated perfused rat kidneys. The kidneys isolated from rats were perfused with 6% PHP, 6% SFH, and 6% hydroxyethylstarch (HES) solution at a constant flow rate. Vascular responsiveness to acetylcholine (ACh), nitroglycerin (NG), norepinephrine (NE), and angiotensin-II (ANG-II) was examined by measuring the perfusion pressure (PP). Effects of inhibition of endothelium-derived relaxing factor (EDRF) by NG -monomethyl L-arginine (L-NMMA) on NE-induced and ANG-II-induced renal vascular responses were examined. ACh and NG induced a dose-dependent decrease in perfusion pressure (PP) in all groups. NE and ANG-II induced an increase in PP in all groups, but NE-induced and ANG-II-induced responses in the PHP-perfused and SFH-perfused groups were significantly larger than those in the HES-perfused group. L-NMMA did not alter vascular responsiveness to NE and ANG-II. These results indicate that PHP and SFH do not inhibit EDRF induced by ACh, but hemoglobin moiety per se does augment the vascular responsiveness to NE and ANG-II in the isolated perfused rat kidney. 相似文献

Due to the great advancements in fetal ultrasonography, the number of prenatal diagnoses are increasing, greatly contributing to improved neonatal surgery. It is now relatively easy to detect huge fetal cystic masses, and we have experienced three cases with a huge neck tumor detected in utero, one case with teratoma and two cases with cystic hygroma. Each case was complicated by neonatal asphyxia, and the neonate needed resuscitation by means of endotracheal intubation. The infant with teratoma unfortunately died of respiratory distress due to compression of the trachea before a perinatal team could be organized. Although the remaining cases with cystic hygroma were treated by a perinatal team, one died 19 hours after birth and the other has survived with the aid of endotracheal intubation in the hospital for three years. In addition, all four cases of cystic hygroma detected antenatally in our institute, which were not delivered, also had fetal hydrops which suggested a general lymphatic derangement. Cystic hygroma detected in utero is considered to be different from that detected after birth, since the former is associated with genetic lymphatic derangement. Prenatal diagnosis enables such patients to survive the perinatal period, but may not improve the prognosis of fetal cystic hygroma so much. 相似文献

Studies on the retention of the mucous-membrane-adhesive anticancer agent hydroxypropylcellulose doxorubicin. 总被引:1,自引:0,他引:1
Incorporation of hydroxypropylcellulose (HPC-)doxorubicin, which we developed as a mucous-membrane-adhesive drug preparation, was instilled into the urinary bladder in 10 clinical cases. Tumor of the urinary bladder was a single tumor in all 10 cases, and preclinical histology showed transitional cell carcinoma, grade 1 or 2, and a lower stage than T1. HPC-doxorubicin, 20 mg/20 ml, was administered in 5 cases, and the other 5 cases received the conventional aqueous doxorubicin, 20 mg/20 ml by way of a catheter and the urethra. Cold punch biopsy was performed after 3 days of instillation, and the incorporation of doxorubicin into both tumorous and normal tissue was measured by high-pressure liquid chromatography. After 3 days, it was found that in the HPC-doxorubicin-administered group, doxorubicin was detected in both tumorous and normal tissue, but it was not detected in either tissue after aqueous doxorubicin administration. In 5 cases of the HPC-doxorubicin group, doxorubicin levels in the tumorous and normal tissue were examined, and it was found that significantly more doxorubicin was detected in the tumorous tissues. Thus, it may be said that our HPC-doxorubicin remained longer within the urinary bladder than the conventional aqueous doxorubicin preparation. Instilled HPC-doxorubicin is more highly concentrated in the tumorous tissue than in the normal bladder tissue, and thus, HPC-compounded anticancer drugs may be therapeutically more useful. 相似文献

The reverse U incision method has been employed for the correction of the unilateral cleft lip nose deformity for more than twenty years with satisfactory results. It has some columella lengthening effect and thus has proved to be useful for the correction of nasal deformities of bilateral cleft lip. To augment its columella lengthening effect a columella relaxation incision is added to the bilateral reverse U incision for the correction of the bilateral cleft lip nose deformity. This results in a reconstructed columella of satisfactory length and width. 相似文献

A murine monoclonal antibody (MDR3M) (isotype: IgM) reactive with mdr3 gene product was generated by immunizing mice with mdr3 -specific peptide (H2 N-12 WRPTSAEGDFELGISSKQKRKKTKTVKMI41 G-COOH) and hybridizing the primed mouse splenic B cells with X63-Ag8,6.5.3 mouse plasmacytoma cells. MDR3M did not cross-react with mdr1 gene product. This monoclonal antibody may be useful for analyzing the role of mdr3 gene product in cells and tissues. 相似文献

The purpose of this study was to determine the relationship between segmental hyperintensity of the liver on T1-weighted images and segmental cholestasis in patients with obstructive jaundice. T1-weighted and T2-weighted MR images were obtained of 73 patients with obstructive jaundice caused by various diseases. Fat-suppressed T1-weighted images were also obtained of 10 patients. Eleven patients with segmental intra-hepatic bile duct dilatation (cholestasis) showed segmental hyperintensity on T1-weighted images and/or fat-suppressed T1-weighted images and no signal intensity difference on T2-weighted images. Sixty-two patients with widespread intrahepatic bile duct dilatation showed no intensity difference on T1-weighted and T2-weighted images (P < .01). Segmental hyperintensity on T1-weighted images was correlated with intrahepatic cholestasis. 相似文献

Abstract: Studies on the circadian rhythm of urine excretion in healthy men have demonstrated that the maximal urine flow occurs in the early afternoon and the minimal around midnight. In this study, an abnormality in the variation of urine volume was found in parkinsonian patients. Urine samples were collected during daytime (9:00–21:00) and nighttime (21:00–9:00). Fifteen healthy control subjects were examined and found to excrete 60% during the daytime and 40% during the nighttime of the total urine volume. Sixteen parkinsonian patients excreted 43% during the daytime and 57% during the nighttime. In contrast to the control subjects, the parkinsonian patients excreted a smaller volume of their urine during the daytime than during the nighttime. This finding might be related to the degeneration of dopaminergic and/or nondopaminergic neurons in the brain which control urinary excretion. 相似文献
