The usefulness of dye-contrast endoscopy for the evaluation of the quality of gastric ulcer healing and the prediction of relapse was investigated. Sixty consenting patients whose ulcers healed during 3 months of treatment underwent endoscopy for the identification of the pattern of mucosal regeneration. Patients were monitored for relapses for up to 18 months after antiulcer therapy had ended. The pattern of regeneration was flat in 24 patients, nodular in 25 and intermediate in 11. Internal hypoechoic areas seen by endoscopic ultrasonography were less common and histological maturity was better in the patient group with the flat pattern compared with the patient group with the nodular pattern of mucosal regeneration. Prostaglandin E, synthesis was highest in the group with the flat pattern of mucosal regeneration and the relapse rate was lowest in this group. We conclude that the evaluation of the quality of ulcer healing is possible and that findings in individuals may aid the prediction of relapse for particular patients. 相似文献

We report a case of leiomyosarcoma of the renal vein, which is a rare tumor with no more than 30 cases found in the published English language literature. This case demonstrates encasement of the renal artery by the tumor mass, a previously unreported manifestation. The present study could be useful in considering this rare tumor in the differential diagnosis of renal hilar tumors. 相似文献

Antiandrogen withdrawal syndrome (AWS) is a well-established phenomenon in prostate cancer. However, responses to AWS are usually of limited duration, and a complete response (CR) is extremely rare. We present two patients who exhibited a chemical CR for more than 2 years after the discontinuation of steroidal antiandrogen chlormadinone acetate use. Whether patients who respond to antiandrogen withdrawal include a group of patients with a better prognosis remains uncertain. However, considering that the usual survival period of patients with hormone-resistant prostate cancer is approximately 12 months, both of the patients reported here, who are present in excellent physical condition, exhibiting an improved quality of life, and attending their hospital as outpatients, obviously acquired a prolonged survival because of AWS. 相似文献

Background and Aim: Although pretreatment with a sedative drug is effective in relieving pain during esophagogastroduodenoscopy (EGD), such drugs can cause significant side‐effects. The aim of this study was to examine the effect of slow‐wave photic stimulation on discomfort and/or pain felt during EGD. Methods: Forty consecutive patients (25 men and 15 women) who underwent diagnostic EGD in our hospital were included in the study. Twenty patients received photic stimulation for 25 min, and underwent electroencephalographic recording, in addition to the usual premedications. Twenty control patients received the same treatment but without photic stimulation. All patients evaluated the discomfort/pain felt during endoscopy against a five‐grade scale in comparison with what they had experienced in their previous examination. Results: Patients with an improved discomfort/pain score were 18/20 and 3/20 in the treated and control groups, respectively. Overall comparison of pain scores between both groups was significant (P < 0.0001). The proportion of slow‐wave activity recorded in patients’ electroencephalograms significantly increased in the treated group compared to control values (36.6 ± 6.8% vs 29.1 ± 3.4%, P < 0.001). There was a close correlation between the degree of discomfort/pain felt during endoscopy and the proportion of slow‐wave activity (P < 0.001). Conclusion: Slow‐wave photic stimulation shows promise as a treatment for relieving the discomfort and/or pain felt by patients undergoing EGD. 相似文献

AIM: The aim of the present study was to elucidate the role of high temperature requirement A2 (HtrA2) in germ cell loss in the heat-stressed testis. METHODS: We examined the expression of HtrA2, caspase-9 activity and proteolytic activity of HtrA2 in the rat testis, and their in vivo responses to experimental cryptorchid treatment. RESULTS: Northern analysis revealed the expression of HtrA2 mRNA peaked at days 1 and 7 after cryptorchid treatment. While expression of HtrA2 mRNA was seen in the spermatogonium, spermatocytes and some spermatids in normal adult rat testis, experimental cryptorchidism treatment resulted in a marked increase in its signal intensity in spermatocytes and some spermatids, and the layers of spermatogonium and early primary spermatocytes became negative at days 1 and 7 after the treatment. However, the spermatogonium, Sertoli cells and interstitial cells appeared to have strong intensities at days 14, 28 and 56 after the treatment. Western analysis revealed the expression of HtrA2 protein peaked at day 2 coinciding with the increase of positive spermatogonium, the appearance of protein-positive interstitial cells, and day 28 coinciding with the reappearance of protein-positive interstitial cells. Caspase-9 activity peaked at day 2 and HtrA2 proteolytic activity peaked at day 28. Consequently, the first peak of HtrA2 mRNA expression was followed by the peak of caspase-9 activity and the second peak was followed by the peak of proteolytic activity; however, the second peak of mRNA expression had considerable chronological difference from that of the protein. CONCLUSION: These findings suggest the probabilities that the heat stress results in germ cell death by a caspase-independent manner with the elevation of HtrA2 proteolytic activity, as well as a caspase-dependent manner with the elevation of caspase-9 activity. 相似文献

A 39‐year‐old woman showed nonsustained polymorphic ventricular tachycardia (PVT) during light physical activity. Cardiac multidetector row computed tomography demonstrated false tendons, one of which proved to be the focus triggering premature ventricular contraction (PVC) in electrophysiological studies. The triggered PVC arose during the diastolic period, which might have caused tension in the false tendon. Radiofrequency catheter ablation targeting the triggered PVC by pace mapping was performed and proved partially effective against PVT. (PACE 2012;35:e341–e344) 相似文献

In order to clarify the characteristics of infectious mononucleosis hepatitis (IMH) in Japan, 20 cases with IMH treated at Kamo Hospital during the past 6 years (Group I) were analysed in comparison with cases of acute viral hepatitis, especially type A. The test for heterophil antibody was positive in only two cases. During the same period 209 cases were treated for acute viral hepatitis (type A: 77 cases = Group A; type B: 61 cases; type non-A, non-B: 71 cases). In Group I the common clinical symptoms and signs were headache, sore throat and lymph node swelling; jaundice was not as common as in Group A. GOT and GPT activities increased moderately in the acute stage, but they were significantly lower than those in Group A. LDH, AP, GGT and LAP activities were disproportionately higher to GPT activity in Group I. Liver biopsy in the convalescent stage showed that lipofuscin deposition and sinusoidal mononuclear cell infiltration were more prominent in Group I, while sinusoidal neutrocyte infiltration and focal necrosis at periportal areas were more common in Group A. Differential diagnosis of the two diseases could be made using these clinical features and histological findings. However, immunological differentiation is required for specific diagnosis because some features such as fever, prolonged elevation of thymol turbidity test, atypical lymphocytes in peripheral blod and predilection for young people were observed in both groups. Furthermore, the present study indicated that IMH is no longer rare and most cases do not demonstrate heterophil antibody in Japan. 相似文献

Serum hyaluronic acid reflects the effect of interferon treatment on hepatic fibrosis in patients with chronic hepatitis C 总被引:1,自引:0,他引:1
MASAHIKO YAMADA YOSHIHIDE FUKUDA YASUO KOYAMA ISAO NAKANO FUMIHIRO URANO YOSHIAKI KATANO TETSUO HAYAKAWA 《Journal of gastroenterology and hepatology》1996,11(7):646-651
Changes in serum hyaluronic acid (HA) in 35 patients treated with interferon (IFN) were studied and the histological change in fibrosis was analysed. Serum HA levels and hepatitis C virus (HCV) RNA were followed from the start of therapy to 12 months after completion of treatment. Histological changes in pre- and post-treatment liver biopsies were assessed using a modified Knodell's scoring system. The serum levels of HA (r = 0.79; P<0.0001) correlated with the degree of fibrosis more closely than with that of amino terminal peptides of type III procollagen (PIIIP; r = 0.45; P<0.05) or type IV collagen (IV-C; r = 0.42; P<0.05). Only complete responders (CR) had a significant decrease in serum levels of HA and IV-C (P<0.05), in parallel with histological improvement (P<0.01). Neither partial responders (PR) nor non-responders (NR) had significant changes in histological scores and in serum levels of fibrotic markers. Significant differences were observed between CR and NR, both in HA levels (P<0.01) and PIIIP levels (P<0.05) 12 months after the cessation of treatment. These results suggest that serum HA is an indicator of the extent of fibrosis in chronic hepatitis C. Serial determinations of serum HA levels may be of use for monitoring the histological response of hepatic fibrosis to IFN treatment in chronic hepatitis C. 相似文献

The effect of human neonatal serum on DNA synthesis in suckling and adult rat hepatocytes in primary culture was investigated to characterize growth regulating factors of the liver in neonates and to confirm whether the stimulatory factor is human hepatocyte growth factor (hHGF). Neonatal serum stimulated DNA synthesis of both adult and suckling rat hepatocytes. The stimulatory effect was dose-dependent up to 20% in volume. The molecular weight of the stimulatory substance in neonatal serum was between 12 500 and 25 000, as estimated by gel filtration. Its activity was stable after heating at 56°C for 20 min, but was lost after heating at 90°C for 30 s, and easily passed through S- or heparin-Sepharose columns. The concentration of hHGF quantified by ELISA was too low to stimulate DNA synthesis in vitro. Biological and biochemical properties of the growth stimulatory activity in neonatal serum differed from that of hHGF. The presence of other growth factors in human neonatal serum for suckling and adult hepatocytes was suggested. 相似文献
