We developed a technique for blind bronchial suction using a curved-tip catheter with a guide mark, for the treatment of atelectasis of the lower and middle lobes of the lung. Suction of the upper lobe bronchi could not be performed because of the combination of the peculiar anatomy of the upper lobe bronchi with catheter design. We treated successfully two cases of atelectasis of the right upper lobes using a Rusch Metras bronchography catheter with a guide mark which is not readily available. Therefore we devised a J-shape tipped catheter with a guide mark. We have successfully treated 13 episodes of atelectasis of the right upper lobe in 10 patients and one episode in the left upper lobe in one patient with this new catheter. 相似文献

Four patients with advanced non-Hodgkin's lymphoma of unfavorablehistology were treated with marrow-lethal doses of cyclophosphamide(CY) and total body irradiation (TB1) followed by the infusionof cryopreserved autologous marrow. All four patients showedengraftment after autologous bone marrow transplantation andachieved complete remission (CR). Three of them, however, developedrelapse in 1.7, 12.9 and 14.5 mo respectively after the transplantation.The other patient has survived in drug-free CR for more than16.6 mo. There was no treatment-related death although therewere some tolerable complications. These data suggest that theCY-TBI regimen may be effective in inducing CR in patients withadvanced non-Hodgkin's disease but it does not contribute topreventing relapse. 相似文献

A morphological approach to cell dynamics is usually difficult, since routine preparative techniques for electron microscopy always induce artifacts due to cessation of the blood supply into organs. An in vivo cryotechnique followed by the freeze-substitution method probably reduces such problems. It was applied for examining the pulmonary alveoli of BALB/c mice in vivo. The following ultrastructural features were revealed. (1) A surfactant layer provided a continuous covering to the alveolar epithelium. (2) Pleural epithelial cells, alveolar cells and endothelial cells contained many small vesicles and pits. In the alveolar epithelium, they were often localised near microtubules. (3) Typical lamellar structures in large alveolar epithelial cells were rarely detected. (4) Circulating erythrocytes with various shapes were observed in branching blood capillaries. (5) A close association between erythrocytes and the endothelium was seen at the peripheral alveolar septum. Such ultrastructural arrangements may be appropriate for the physiological functions of the pulmonary alveoli, such as exchanges of gases or materials in vivo. 相似文献

Overexpression of c-erbB-2/neu/HER-2 oncoprotein, a receptor tyrosine kinase, has been demonstrated in a variety of human cancers. To elucidate the involvement of c-erbB-2 in human skin carcinogenesis, we examined expression of the protein in skin samples from five cases of keratoacanthoma (KA), 10 of actinic keratosis (AK), 24 of squamous cell carcinoma (SCC) and 10 of basal cell carcinoma (BCC) and five samples of normal epidermis, using an immunohistochemical method on formalin-fixed, paraffin-embedded sections. Expression of c-erbB-2 was also examined in cultured SCC cell lines, a premalignant cell line and in cultured normal keratinocytes. Normal epidermal cells showed no or very little c-erbB-2 protein, but the covering epidermal layer of some tumours showed a few strongly positive cells. Samples of KA and AK showed barely detectable c-erbB-2 protein in only a few cases. Twenty of the 24 cases of SCC had elevated expression of c-erbB-2 protein with a tendency to more positive cells in metastatic lesions. Five of the 10 cases of BCC stained for c-erbB-2 but more weakly than those of SCC, Reaction products of the positive cells were seen in the cytoplasm. All three cultured SCC cell lines stained for c-erbB-2 protein more strongly than the premalignant HaCaT or normal keratinocytes. Our results indicate the possible involvement of c-erB-2 overexpression in the malignant conversion of keratinocytes. 相似文献

We report a case of mirror‐image dextrocardia with antidromic atrioventricular reciprocating tachycardia via the Mahaim fiber. Using the noncontact mapping system, arborized ventricular insertion of the Mahaim fiber was identified and successfully ablated. (PACE 2010; e102–e105) 相似文献

A 72-year-old Japanese man presented with a painless swollen left scrotal mass with elevated levels of serum alpha-fetoprotein and prostate specific antigen. The patient underwent high orchiectomy under diagnosis and a final pathological examination revealed embryonal carcinoma of the left testis. A systematic needle prostate biopsy under guidance of transrectal ultrasound revealed prostate cancer (Gleason score, 8) on the left lobe (T2aN0M0). Systemic chemotherapy was given for retroperitoneal lymph node metastasis of testicular cancer and hormonal therapy (LH-RH analog) was given for prostate cancer. The patient was well with no evidence of metastasis from the testicular cancer or prostate cancer and with no elevation of serum alpha-fetoprotein or prostate specific antigen 26 months after the orchiectomy. 相似文献

ABSTRACT. Erythrocyte sodium and potassium were studied in 64 newborn infants including 21 very low birthweight infants (birthweight < 1500 g) during the first three days after birth. Erythrocyte sodium showed a positive correlation with gestational age ( r =0.63, p <0.01) and birthweight ( r =0.66, p <0.01). Erythrocyte potassium was negatively correlated with birthweight ( r = -0.33, p <0.05). The Na/K ratio in red blood cells showed a positive correlation with gestational age ( r =0.60, p <0.01) and birthweight ( r =0.65, p <0.01). In VLBW infants plasma potassium rose significantly ( p <0.01) from 0–6 h to 12–30 h and decreased from 12–30 h to 30–60 h ( p <0.05). Erythrocyte potassium decreased slightly from 0–6 h to 12–30 h, but not significantly. A new finding that "more immature infants have higher potassium and lower sodium concentration in RBC" may suggest a potential risk of hyperkalaemia in tiny infants. 相似文献
