Renal localization of gallium-67 citrate 总被引:1,自引:0,他引:1

The authors describe the use of a desk-top computer to analyze processor status. Quality control data (sensitometry, densitometry, thermometry, etc.) are collected conventionally. Analysis of the data is subsequently performed using specially designed software. This computer analysis results in a small savings in time and in greatly improved management and presentation of quality control data. 相似文献

甘草类黄酮对四氯化碳致小鼠急性肝损伤的影响 总被引:48,自引:0,他引:48
甘草类黄酮(GF)是从甘草根中提得。本文结果表明,预先ig GF 200,400,600mg·kg-1·d-1×2d能显著降低CCl4所致血清谷丙转氨酶,乳酸脱氢酶活性的升高以及肝内丙二醛含量的增加,其作用呈剂量依赖性。GF可减轻CCl4所致的肝脏坏死,但对血清内酶的活性没有抑制作用,也不减少正常小鼠血清中酶的活性。GF的肝保护作用可能与其抗脂质过氧化作用有关。 相似文献

Localized phosphorus-31 magnetic resonance (MR) spectroscopy in humans has previously been accomplished with surface coils by means of depth-resolved surface coil spectroscopy or rotating frame experiments, in which the extent of tissue sampled critically depends on surface coil placement. The authors' goal was to modify the surface coil image-selected in vivo spectroscopy (ISIS) experiment to accomplish three-dimensional volume selection through application of selective pulses in the presence of B0 gradients. Advantages of ISIS include the ability to use proton images to define the volume of interest (VOI) and reduced dependence on exact positioning of the surface coil. However, rapid replication of the surface coil ISIS experiment can cause spectral contamination from signals originating outside the VOI. A modified version of the ISIS experiment was developed to alleviate contamination under conditions of rapid replication. Applications of localized P-31 MR spectroscopy for observation of high-energy phosphorus metabolites are presented in human liver, heart, and transplanted and normal kidney. 相似文献

Background
Medical Termination of Pregnancy (MTP) is a commonly performed during the first trimester. Dilatation and Evacuation (D & E) mandates rapid dilatation of cervix with metal dilators, which requires anaesthesia and may be associated with trauma to the uterus, cervix and later cervical incompetence. The problem of rapid cervical dilatation is obviated with intravaginal misoprostol.Methods
Intravaginal misoprostol tablet 200 microgram was inserted, a night prior to MTP to ripen the cervix. Cervix was dilated with metal dilators only in cases where cervix did not loosen up sufficiently. Products of conception were removed by suction.Results
Out of 108 cases cervical dilatation was not required in 96 cases (88.9%).Conclusion
Intravaginal misoprostol 200 microgram proved effective as a priming agent prior to MTP in the first trimester.Key Words: Misoprostol, MTP 相似文献68.

Background
Laparoscopic donor nephrectomy (LDN) has been gaining popularity among kidney donors. There have been concerns about the safety and efficacy of the procedure as compared to open donor nephrectomy (ODN). We compare our results on LDN with ODN.Methods
We retrospectively analysed our data of LDN and ODN. Duration of surgery, blood loss, period of hospitalisation, per oral intake and analgesic requirements.Result
22 LDNs were done, the operation time ranged from 220-300 minutes, and blood loss from 100-150ml. In the first 10 laparoscopic operations four cases required conversion to open surgical dissection. Only one case was converted to open surgery in the subsequent 12 laparoscopic cases. Oral intake was started on the first postoperative day. Analgesic requirement in laparoscopy cases was less. Patients were mobilised on the first day after surgery. Patients were discharged by seventh day. There was no significant difference in the functioning of the graft after revascularisation in the recipient.Conclusion
Laparoscopic donor nephrectomy is a safe and effective technique of donor nephrectomy.Key Words: Laparoscopy, Laparoscopic donor nephrectomy, Living kidney donors, Kidney transplantation 相似文献69.
Background
Monoclonal gammopathies occurs in patients with malignant diseases of plasma cells and lymphocytes and in few benign conditions. The objective of this study was to assess the precision, accuracy and confirmation of monoclonal gammopathies on serum protein electrophoresis (SPE) and the clinical relevance of detection and characterization of M component.Methods
All samples received for serum electrophoresis in the last 3 years were analysed for data on M band positivity and correlating it with clinical profile of the patients. Immunofixation (IFE), Immunoelectrophoresis (IEP) and IgG, IgM estimation were carried out in few cases. The follow up of cases was done by serial monitoring of SPE and β2 microglobulin levels.Results
1155 samples were received during the 3 years period. 282 (24.4%) samples were positive for M component on SPE. Of these, 239 (84.8%) patients had M spike in λ region and 43 patients had M spike in β region. The mean load of the M protein band in the λ region was 37.8% and in β region was 35.8%. IgG with κ chain was seen in 40%, IgG with λ chain was seen in 50%, 5% patients each had IgM with κ and IgA with λ light chain. 246 samples (96.5%) had high levels of β2 microglobulin. Of the 116 cases of multiple myeloma, IgG levels was more commonly raised (5%) as compared to IgA (6.9%) and IgM (5.2%).Conclusion
It is recommended that SPE should be performed in patients having unexplained weakness, anaemia, back pain, osteoporosis, osteolytic lesions, fractures, renal insufficiency or recurrent infections.Key Words: Serum protein, Electrophoresis, M band, Multiple myeloma 相似文献70.
