ABSTRACT: We have established two monoclonal antibodies (TM7-3 and TM3-8) that react to choriocarcinoma cells. Both of these monoclonal antibodies have shown a similar reactive pattern to human cell lines, normal and neoplastic trophoblast tissues, and other fetal and adult tissues. They have reacted to nine of the ten choriocarcinoma cell lines, as well as to Hela cells (a cervical carcinoma cell line). During a cellular radioimmunoassay, neither TM7-3 nor TM3-8 reacted to two T lymphoblastoid cell lines or three B lymphoblastoid cell lines. Immunofluorescence and immunoper-oxidase staining showed that both monoclonal antibodies reacted selectively to the cytotrophoblast-like tumor cells of a choriocarcinoma and a hydatidiform mole but not to syncytiotrophoblast-like tumor cells. TM7-3 and TM3-8 also reacted slightly to the normal cytotrophoblast of early human chorionic villi under the same conditions as they did to choriocarcinoma tissue, but not to syncytiotrophoblast. In various normal tissues, TM7-3 and TM3-8 bind only to a part of the urinary tubles of the kidney and to the ducts of the pancreas of both adult and fetus. 相似文献

The movement of the carpal bones in gripping was clarified in the giant panda ( Ailuropoda melanoleuca ) by means of macroscopic anatomy, computed tomography (CT) and related 3-dimensional (3-D) volume rendering techniques. In the gripping action, 3-D CT images demonstrated that the radial and 4th carpal bones largely rotate or flex to the radial and ulnar sides respectively. This indicates that these carpal bones on both sides enable the panda to flex the palm from the forearm and to grasp objects by the manipulation mechanism that includes the radial sesamoid. In the macroscopic observations, we found that the smooth articulation surfaces are enlarged between the radial carpal and the radius on the radial side, and between the 4th and ulnar carpals on the ulnar side. The panda skilfully grasps using a double pincer-like apparatus with the huge radial sesamoid and accessory carpal. 相似文献

BACKGROUND: Among full-term neonates, the authors discovered infants who showed respiratory inhibition after crying which involved a marked decrease in SpO2. The infants were found to present increased echogenicity or a cyst in a cranial region termed the ganglionic eminence, or to have a subependymal cyst. The authors prospectively examined the relationship between respiratory inhibition after crying and these changes to examine the prevention and treatment of the episode. METHODS: The authors conducted cranial ultrasonography to screen 381 full-term neonates who showed no abnormalities at birth and whose parents requested ultrasonographic screening of the head, followed by polygraphy of infants who showed increased echogenicity or a cyst in ganglionic eminence, or had a subependymal cyst. The authors similarly conducted polygraphy for 50 neonates without cranial ultrasound abnormalities; the former constituted the control group. Respiratory inhibition was defined to be central apnea immediately after crying with a decrease in SpO2 to <60%. RESULTS: Among 381 neonates examined, 104 showed cranial ultrasound abnormalities; 60 of the 104 neonates indicated respiratory inhibition after crying. Oxygenation failed to improve the episode in 17 neonates with severe respiratory inhibition. However, theophylline alleviated the episode, and SpO2 no longer decreased to <60%. Theophylline was discontinued successfully by 6 months after birth, while 50 neonates in the control group showed no respiratory inhibition after crying. CONCLUSION: Respiratory inhibition after crying which involved a marked decrease in SpO2 was observed in full-term neonates who showed no abnormalities after birth. These neonates could be screened by cranial ultrasonography. 相似文献

A case of erosion of a penile prosthesis caused by indwelling of a catheter in the urethra is reported. A 73-year-old man had maintained sexual intercourse with penile prostheses (Jonas prosthesis, 19 cm) for 11 years without any complications until he developed cerebral infarction. One month after starting an indwelling urethral catheter in a neurosurgery clinic, the left-side penile prosthesis eroded from the area of the fossa navicularis, and was immediately removed. This type of complication is not unusual in patients with a neurogenic bladder. However, it is not well recognized in patients who suddenly develop a neurogenic bladder following a long-term uneventful period after the implantation of penile prostheses. Therefore, urologists should inform patients who receive this type of treatment that erosion of the prosthesis may develop when they need an indwelling urethral catheter as a late complication. 相似文献

BACKGROUND: KL-6 in umbilical cord blood, including from premature infants, and perinatal factors that may affect these values have not yet been adequately discussed. The authors investigated factors affecting cord venous plasma levels of KL-6 in neonates, and to establish a normal range of values for KL-6 in neonatal cord blood. METHODS: Cord plasma levels of KL-6 were measured in 75 neonates, and statistical analysis of factors affecting these levels was performed. A normal range for cord plasma KL-6 levels was calculated by statistical analysis methods based on guidelines by the National Committee for Clinical Laboratory Standards. RESULTS: Data from a total of 75 neonates was analyzed. Gestational age ranged from 25 to 40 weeks (median, 33.4 weeks), and birthweight ranged from 776 to 3760 g (median, 1944 g). There was no statistically significant correlation between cord plasma KL-6 levels with gender, gestational age, birthweight, method of delivery, Apgar score 1 min, and postnatal respiratory distress. The normal range of values for cord plasma KL-6 was 44.3-148.2 U/mL (median, 73.0 U/mL). CONCLUSION: The cord plasma levels of KL-6 were about half the normal values reported in children and healthy adults and were not affected by various perinatal factors. The authors' findings suggest that plasma KL-6 levels rise when respiratory function is established after birth and tend to further increase with age. 相似文献

Summary. Three cases of acute leukaemia with t(4;12) (qll-12;pl3) karyotypic abnormalities were analysed. They had the following common clinical and biological characteristics: (1) dysplasia of three haemopoietic lineages; (2) absent or low myeloperoxidase activity; and (3) retention of platelets in the peripheral blood and megakaryocytes in the bone marrow. There were increased numbers of basophils in the bone marrow and peripheral blood in two of the cases. In all, the blast cells displayed the unique immunophenotype CD7+ CD13+ CD34+ HLA-DR+ . The blasts analysed in one case expressed c-kit on the membrane surface. These findings suggest that the t(4:12) (qll-12:pl3) abnormality is associated with a particular type of acute leukaemia, one in which the morphology and immunophenotype suggest that the translocation may have occurred at an early stage of haemopoiesis. 相似文献

A case of metastasis to the prostatic urethra after transurethral resection of the prostate from a previously resected renal cell carcinoma (RCC) is reported here. Solitary urethral metastasis from RCC is extremely rare. Only four cases of urethral metastasis from RCC have been previously reported in the literature. 相似文献

The interaction of amine local anaesthetics and related compounds with histamine H1 receptors was investigated in guinea-pig ileal longitudinal muscle. Quinacrine, chloroquine, tetracaine and procaine inhibited [3H]mepyramine binding to solubilized membrane from ileal muscle with pKi values of 5.27 ± 0.11, 5.66 ± 0.01, 4.28 ± 0.08 and 3.97 ± 0.11, respectively. The pKB values obtained from the initial parallel shift of the dose-response curves for histamine in the presence of these drugs were 549 ± 0.11, 6.14 ± 0.09, 4.86 ± 0.06 and 4.58 ± 0·06, respectively, in reasonable agreement with the pKi values. The combined dose-ratio test with both local anaesthetics and antagonist (mepyramine) present showed that tetracaine and procaine were competitive and chloroquine was partially competitive, but that quinacrine was not competitive at histamine H1 receptors. These local anaesthetics inhibited histamine-induced desensitization in guinea-pig ileum. Receptor occupancy (%) by agonist decreased from 95.2 (without inhibitor) to 73.9, 42.8, 35.9 and 33.9 in the presence of quinacrine, chloroquine, tetracaine or procaine, respectively, under the conditions where each inhibitor drug induced half maximum inhibition of desensitization. The results suggested that most of these local anaesthetics interacted competitively at histamine H1 receptors and inhibited desensitization through their antagonizing actions, whereas quinacrine interacted allo-sterically and inhibited desensitization through a separate action. 相似文献
