A retrospective analysis was performed to evaluate the clinicalsymptoms and abnormal test findings in small pancreatic carcinoma.Five hundred and thirty-six cases of pancreatic carcinoma withthe histology of duct cell carcinoma were collected from 14medical centers in Japan. In 440 of the cases, tumor size wasmeasured at the time of laparotomy or from the resected specimen.Three hundred and seventy-seven patients (86%) had a carcinomalarger than 3.0 cm; only 30% of these were resectable. Sixty-threepatients (14%) had a carcinoma of 3.0 cm or less, with resectabilityof 97%. Detecting a tumor of "3 cm or less" with a high probabilityof resectability is the objective of early diagnosis with theresulting possibility of a cure. In most cases these small carcinomaswere found easily when obstructive jaundice was present (73%).However, the estimated occurrence of obstructive jaundice associatedwith carcinomas of 3 cm or less was only 10% among the totalcases of pancreatic carcinoma studied. Therefore, it is necessaryfor early diagnosis to detect carcinomas of 3 cm or less presentingwithout jaundice. The symptoms of small carcinoma without jaundiceare weight loss, anorexia, upper abdominal pain, back pain anda palpable abdominal mass. Among the various available examinations,endoscopic retrograde cholangiopancreatography, computerizedtomography and ultrasonography were valuable in diagnosing thesesmall carcinomas. 相似文献

Cyclic AMP (cAMP) output in the duodenal contents of 11 normal subjects, 18 patients with chronic pancreatitis, six convalescing from acute pancreatitis and five with pancreatic carcinoma was measured after a single dose of pancreozymin and secretin. The technic was indirect, utilizing recovery of duodenal contents by the Dreiling tube rather than direct measurements of fluid that was not contaminated by bile. In all patients groups, cAMP output reached a peak after this stimulation with a concomitant increase of bicarbonate and amylase outputs. A significantly decreased cAMP output was observed in all pancreatic disease groups compared to the normal group. Patients with chronic pancreatitis showed a slightly decreased cAMP output, considerably decreased bicarbonate output and normal amylase output. In acute pancreatitis cAMP output was reduced with normal bicarbonate and amylase outputs. In pancreatic carcinoma cAMP decreased significantly, bicarbonate output was moderately reduced and amylase output was normal. cAMP output in all groups studied did not correlate with either bicarbonate output or amylase output. 相似文献

Bioelectorical impedance methods have been found to be a valid and reliable way of estimating per cent body fat (%BF) in adults. We applied them to healthy children and compared them with conventional anthropometry methods. One thousand two hundred and sixteen children participated in this study. Impedance and skinfold thickness were measured, and %BF was estimated using these values. Bodyweight and height were measured, and per cent obesity (%OB) and body mass index (BMI) were obtained. The values of %BF by the bioelectrical impedance method (%BFi) were 8.6 ± 4.0% in the junior male group, 14.2±2.8% in the junior female group, 7.9±4.7% in the senior male group and 16.1 ±2.9% in the senior female group. The % BFi correlated strongly with skinfold thickness, %OB and BMI. Thus %BFi correlated strongly with variables from conventional methods. It was concluded that it is a reliable way of assessing lipid storage in children. 相似文献

Although biocompatibility of biodegradable stents is controversial, stents made of high molecular weight poly- l -lactic acid (PLLA) are thought to be the most promising. We investigated the biocompatibility of PLLA stents histologically and angiographically in porcine coronary arteries. The Igaki-Tamai stent is made of PLLA monofilaments (molecular mass 183 kD) with a zigzag helical coil design. Fourteen PLLA stents in 6 pigs and 9 Palmaz-Schatz half stents in 9 pigs were implanted in 15 normocholesterolemic pigs. Stents were mounted on a delivery catheter, and were implanted percutaneously into coronary arteries. Coronary angiography was performed before and immediately after stenting, at 2 and 6 weeks in five PLLA pigs and nine Palmaz-Schatz pigs. Histological studies were performed in PLLA pigs: 2 pigs at 2 weeks, 3 pigs at 6 weeks, and 1 pig at 16 weeks with hematoxylin-eosin and elastica van Giesons stains. All PLLA stents were successfully delivered. No stent thrombosis was detected in either group. There were no significant differences in minimal lumen diameter (MLD) or percent diameter stenosis between the PLLA and Palmaz-Schatz stent groups immediately after implantation, or at 2 or 6 weeks after implantation. Histological studies at 2, 6, and 16 weeks revealed no inflammation and minimal neointimal coverage on the PLLA stent struts. The PLLA stent maintained its structure for up to 16 weeks. These results suggest sufficient biocompatibility and strength of PLLA biodegradable stents in porcine coronary arteries. Clinical trial is now underway to validate the safety and usefulness of PLLA stents in humans. 相似文献

A 13-year-old-boy with suspected left testicular torsion was referred to our institute. During preparation, a significant decrease of signals on the left testis was found, however, slight blood flow was detected by the ultrasound examination enhanced by Levovist. As a result of the examination we left the testis intact, although the color of the testicular parenchyma remained black. One year after the surgery, an ultrasound examination was done again and good vascurality was observed. 相似文献

ABSTRACT: Using concanavalin A (Con A) crossed-line affinity immunoelectrophoresis and lentil lectin (LCH) crossed-line affinity immunoelectrophoresis, alpha-fetoprotein (AFP) subfractions were studied in sera including three sera from nude mice heterotran-splanted with human yolk sac tumor of the ovary and three sera from patients with yolk sac tumor, mature solid teratoma, or immature solid teratoma of the ovary. In sera of nude mice bearing yolk sac tumor or from a patient with yolk sac tumor, subfractions from yolk sac and those from fetal liver were identified. Since AFP subfractions from yolk sac and fetal liver can be differentiated according to the carbohydrate moieties, our findings indicate that AFP produced by yolk sac tumor and fetal yolk sac are to some extent differently glycosylated. We also found that AFP in both mature and immature solid teratoma was composed of two subfractions ontogenetically originating from yolk sac or fetal liver. All these findings indicate that more than two different factors are responsible for the AFP synthesis in germ cell tumor of the ovary. 相似文献
