The developmental appearance and regulation of hypothalamic vasopressin (prepropressophysin) mRNA was studied using quantitated in situ hybridization techniques. Vasopressin mRNA levels in the supraoptic nuclei were reliably detected on day 16 of gestation, while mRNA in the suprachiasmatic nuclei (SCN) was detectable on day 21. These developmental patterns correlate well with the immunohistochemical appearance of prepropressophysin translation products previously reported in these nuclei. A prominent day-night rhythm of vasopressin mRNA levels was evident in the SCN on day 21 of gestation; the rhythm was also present on postnatal days 2 and 11. No such rhythm was present in the supraoptic nuclei at any developmental stage examined. These results demonstrate regulated expression of the vasopressin gene during fetal life. Vasopressin mRNA levels in the SCN are already under specific circadian control when the nuclei are morphologically immature and lacking many of the connections found in adult animals. 相似文献

Foam sclerotherapy combined with surgical treatment for recurrent varicose veins: short term results. 总被引:1,自引:0,他引:1
OBJECTIVE: To study the short term results of combined peroperative foam sclerotherapy (PFS) and surgical treatment for recurrent varicose veins. METHODS: PFS was used to treat 129 limbs with recurrent varices: 100 great saphenous (GSV), 29 small saphenous veins (SSV). Foam was prepared with 1% polidocanol mixed with 4 times its volume of air. The 100 GSVs comprised 28 trunks directly connected with the femoral vein, 28 connected to a lymph node venous network, 11 associated with perforators and 33 isolated trunks. The 29 SSVs comprised 4 trunks directly connected to the popliteal vein, 7 isolated trunks, 15 popliteal perforators and 3 recanalisations after SSV stripping. All operations included phlebectomies. In twenty limbs re-ligation of the SFJ and 4 SPJs was carried out. All were performed under local anaesthesia in an ambulatory setting. Patients were assessed clinically and by colour duplex ultrasound after 3 and 40 days follow-up. RESULTS: 120 patients (93%) showed complete obliteration of saphenous trunks, junctions and varices. The 9 incomplete obliterations were 3 venous recanalisations in the SSV compartment and 6 perforators (4 popliteal and 2 femoral). Two asymptomatic deep venous thromboses were detected by colour duplex 3 days after operation. CONCLUSION: PFS facilitates surgical treatment of recurrent varicose veins. There is a small risk of post-operative deep vein thrombosis. 相似文献

Taurolidine (TRD) has antimicrobial and anti-inflammatory properties. However, the anti-inflammatory effects of TRD in inflammatory bowel diseases (IBD) have not been investigated. Here, we have analyzed the toxicity of TRD after oral long-term application in mice and examined the impact of oral TRD in a dextran sulfate sodium (DSS) model of experimental colitis. Female C57/BL6 mice received TRD in various concentrations (0.1% to 0.4%) for 60 days. Toxicity was evaluated by use of a disease activity index (DAI) and histological examination of major metabolic organs. Furthermore, the impact of 0.2% TRD on a chronic DSS colitis was examined by daily DAI, histological crypt damage score (CDS), bacterial translocation into mesenteric lymph nodes (MLN), and colonic expression of tumor necrosis factor (TNF) alpha, transforming growth factor (TGF) beta, interleukin (IL)-1beta, IL-6, cytochrome oxidase (COX)-2, and monocyte chemotactic protein (MCP)-1 by real-time polymerase chain reaction (PCR). Oral TRD administration for 60 days was well tolerated by the animals and did not show any toxic effects in terms of DAI and histological changes. TRD treatment of DSS colitis led to increased survival of 100%, compared to 33% in the untreated colitis group (p < or = .005). Clinical amelioration was mirrored by significantly reduced DAI and CDS in the TRD treated colitis. Colonic cytokine expression and bacterial translocation into MLN showed no differences between both groups. We thus report for the first time that oral application of TRD results in amelioration of an experimental IBD model. We hypothesize direct intraluminal antimicrobial effects of TRD as well as anti-inflammatory effects during the acute phase of DSS colitis. 相似文献
