Increased hypothalamic dopamine turnover may prevent the ovulatory LH peak by different mechanisms and may in this way result in anovulation. Ten patients with anovulatory menstrual cycles who had been treated with clomiphene citrate without success were given the dopaminolytic drug pimozide (Antalon) at a dose of 5 mg/day orally either from day 7 to day 11 (7 women; group 1) or from day 11 to day 15 of the menstrual cycle (4 women; group 2). One patient from group 2 ovulated during the treatment cycle. A further woman from this group exhibited an LH peak, but did not ovulate, whereas a slow increase of the circulating LH level was recorded in the remaining two patients. Systematic investigations should clarify whether introduction of dopaminolytic therapy in the treatment of hypothalamic anovulation may be justified. 相似文献
Background: The isoxal derivative, leflunomide (LF), is a new potent immunosuppressive which has been shown to be effective in preventing autoimmune disorders and reactions leading to organ transplantation rejection. LF is thought to antagonise cytokine activity and thereby to interfere with T-helper-cell-dependent B- and T-lymphocyte proliferation. Methods: We used LF to treat corneal allograft rejection in the rat, comparing its effect with that of cyclosporin A (CSA). Corneal buttons were grafted from Lewis/Brown Norway rats to Lewis recipients. Animals were randomly assigned to the following treatment groups: I, untreated; II, CSA (10 mg/kg i.m.); III, LF (2.5 mg/kg p.o.); IV, LF (5 mg/kg p.o.); V, LF (10 mg/kg p.o.); VI, combined therapy (LF 10 mg/kg p.o. and CSA 10 mg/kg i.m). Treatment began on the first postoperative day and was continued until rejection occurred. Results: The mean graft rejection time in the untreated allogeneic group was 12 days. A significant delay in graft rejection was observed in all treatment groups compared with group I (P<0.001). Further, the delay in graft rejection resulting from combined therapy (group VI) was statistically significant compared with all other groups (P<0.001). Conclusion: These results suggest that (a) LF when used alone is as effective as CSA in treating corneal allograft rejection in the rat, and (b) when LF and CSA are combined they are more effective than either drug alone in the prolongation of allograft survival.Presented in abstract form at the Berlin-Brandenburg Eye Congress, 4–5 December 1993.

The 3rd World Integrative Medicine Congress (3rd WIMCO) was held on September 22-24, 2007 in Guangzhou, China. The Congress has showed the academic achievements of integrative medicine in the recent five years covering a wide range of fields, such as basic and experimental research; clinical research; theory, education and management research; new drug research and development; and application of evidence-based medicine. 相似文献
Background: At present, there are no meaningful and sophisticated computer games that simultaneously allow the treatment of movement disorders such as Parkinson's syndrome. In particular, there are no systems to consider the severity of the disease and the physical skills of the patient.
Methods: A computer game using the Microsoft Kinect as markerless sensor for the 3?D recognition of the patient’s movement was developed to support the rehabilitation. The scenario of a basketball game was created after determining that the movement like throwing a ball and the correct posture of the body are important. A study based on system usability was performed with 15 patients to evaluate the system.
Results: The technical feasibility of a computer-assisted training system for supporting patients with Parkinson‘s disease has been demonstrated. No markers on the patient are required for movement detection and allow a user-friendly handling. Regarding the usability study, the patients were accepting of such a system and its at-home use and symptoms like ‘freezing’ and the Pisa syndrome can be treated.
Conclusions: The physiotherapist can be assisted by the developed rehabilitation system. An objective measurement of the patient’s training progress delivers valuable information to adjust the training sessions for every patient individually. Due to its modular character, the system can also be applied to other diseases or sports injuries and offers the basis for further development. 相似文献
Respiratory morbidity in Inuit children is high. However, little is know regarding lung function measures in this population. The forced expiratory volumes in one second (FEV(1)) and forced vital capacity (FVC) in 888 Greenlandic Inuits (N=888) and Danes (N=477) aged 6-18 years were compared. Furthermore, associations between level of lung function and atopy and lifestyle factors were estimated in Greenlanders. The effect of height on FEV(1) and FVC was significantly different in Greenlanders and Danes, this difference in lung function increased with increasing height, and could not be explained by differences in age weight and BMI. Thus, Greenlanders taller than 130 cm had up to 300-400 ml higher FEV(1) and FVC compared with Danes of the same height. Among Greenlanders, those living in settlements had the highest levels of both FEV(1) and FVC. Greenlanders had elevated levels of FEV(1) and FVC compared with Danes. The Inuit having a shorter limb length in relation to trunk height may account for these differences. However, our finding that Greenlanders living in settlements had the highest lung function level also suggests a possible role of factors in the traditional Greenlandic lifestyle. 相似文献
Although chemoembolization is known to be an effective palliative treatment in hepatocellular carcinoma, it has a limited effect in large tumors. We report the case of a patient with a large hepatocellular carcinoma of the left liver who had a significant and sustained clinical response after six sessions of chemoembolization with a pirarubicin/amiodarone/lipiodol emulsion. Pirarubicin is an anthracycline which penetrates faster than doxorubicin into cancer cells. Amiodarone is a multidrug resistance inhibitor. Polysorbate 80, an excipient of injectable amiodarone stabilizes the anthracycline/lipiodol emulsion. The clinical efficacy of this new formulation could be evaluated in a phase II clinical trial. 相似文献
Our aim was to analyze the existing body of evidence about inpatient care of patients suffering from rheumatoid arthritis (RA). The report was induced by the executive board of the German Society of Rheumatology which assigned the "Oliver-Sangha committee" to dissect and point out the tasks of inpatient care during the next few years. A systemic search of the literature was performed covering the years 1966 to 2001. A total of 16 studies were selected and thoroughly appraised in a systematic way. Four randomized controlled trials addressing the question could be identified. All of them included only patients in a clinical condition allowing outpatient care as well. Two studies indicate some advantage of inpatient care in comparison to outpatient treatment. Two studies, both equivalence studies from design, reveal that RA patients do not generally experience additional benefit from hospitalization. Consideration of two additional cohort studies demonstrates the increased need of inpatient care in RA patients. None of the studies was derived from the German health care system. Emergency cases were not the subject of any of these trials. General statements about the value of inpatient care of RA patients can not be drawn from the analyzed studies. The committee makes suggestions for future investigations that may help to answer this important question considering the special circumstances of the German health care system. 相似文献
