重点对 380 0～ 30 0 0cm- 1 范围的红外吸收光谱在鉴别天然与合成紫晶中的适用性和局限性进行了研究。36 80 ,36 6 4 ,36 30cm- 1 处吸收带的存在可以确认紫晶为人工合成的 ,但仅指那些在近中性NH4F溶液中合成的紫晶。相反 ,商业上大量的合成紫晶是在碱性K2 CO3溶液中合成的 ,这些紫晶的红外吸收光谱并无明显的鉴定特征。前人的研究发现了在近 35 95 ,35 4 3cm- 1 处吸收带的潜在鉴定价值。35 95cm- 1 吸收带在合成紫晶的红外吸收光谱中并未出现 ,在一些天然紫晶中也常常缺失。35 4 3cm- 1 吸收带出现在绝大多数碱性溶液中合成紫晶的红外吸收光谱中 ,但有时也在天然紫晶中出现。因此 ,它只是鉴别合成紫晶的临时性证据。35 4 3cm- 1 吸收带在有些类型的合成紫晶中缺失。要准确地鉴定天然与合成紫晶一定要根据其红外光谱、内部生长结构 (包括双晶 )

RESULTS:97 patients completed the study according to the protocol(1 patient of the OAM group did not come to the control endoscopy,2 patients of the OAA group stopped the treatment because of mild allergic urticaria).Duodenal ulcers were healed in 48 patients of the OAM group(96 %, C190.5-100 %)and in 46 patients of the OAA group(92 %, CI 89.5-94.5 %)(p=ns).*** was eradicated in 15 out of 50 patients with OAM(30 %,CI 17-43 %)and in 36 out of 50 patients treated with OAA(72 %;CI 59-85 %) (Pvc\ the majority of patients, which is an essential argument to withdraw this regimen out of the national recommendations. Macrolide with amoxicillin are preferable to achieve higher eradication rates. Azithromycin (1 g od for the first 3 days) can be considered as a successful component of the triple PPI-based regimen.

The Recovery of Complicated Upper Limbs Movement Functions of Poststroke Patients

1998 International Conference on Neural Networks and Brain(ICNN&B’98)

作者： vladimir E.bondarenko Alexander v.Rusev Institute of Biochemical Physics Russian Academy of Sciences

＜正＞Controlling chaos by an external periodic pulsed force is considered in an asymmetric analog neural network with time delay. Quantitative characteristics of the outputs （spectrum,correlation dimension and largest Lyapunov exponent） are *** is pointed out that the external periodic pulsed force allows to produce transitions "chaosorder" and "order-chaos".Two cases of chaos control are considered:1) resonant case when the frequency of external pulsed force is close to the eigenfrequency of spontaneous neural network activity or its harmonic;2) non-resonant case when the frequency of external pulsed force is not equal to any of eigenfrequencies of spontaneous oscillations. The results of numerical simulation allow to explain some experimental results on controlling chaos in the brain.

In chronic stage of stroke, it is necessary to pay attention to the complex spatial movements training along with the traditional restoration of balance, strength of particular muscles, and paretic limb joints mobility. The aim of the study was to evaluate the effectiveness of robotic therapy in the recovery of upper limb function in the chronic stage of stroke. The study involved 52 patients with ischemic stroke in the middle cerebral artery. The patients were divided randomly into 2 groups. All patients （5 days/wk × 3 wk） got gymnastics by the standard technique, massage, laser, and pulsed currents therapy. Main group patients （n = 36） extra received complex spatial movements, speed, fluidity, precision and agility training by the robotic electromechanical device Multi Joint System （MJS）（40 minutes, 5 days/wk × 3 wk）. Analysis of the results of the study showed a statistically significant difference in improving ROM of the elbow and shoulder joints, speed and accuracy of movement in the main group compared with the control. Hardware recovery of complex spatial upper limb movements in the chronic stage of stroke increases the functionality and independence of the patient＇s domestic skills.

Bartonella are known to be important causes ofzooanthroponotic diseases. The range of human infection varies from mild lymphadenopathy and asymptomatic bacteremia to life-threatening systemic disease in immunocompromised patients. Microbiological improvements in isolation methods and PCR amplification of organism-specific DNA sequences have resulted in a dramatic increase in reports describing human patients with bartonellosis. Nevertheless, clearly and successful isolation ofBartonella spp. from bacteremic animals and human patients remains an ongoing challenge. Technology of experimental bartonellosis due to intraperitoneal introduction of biological material samples containing causative agents to laboratory animals is presented in the article. White nonlinear mice with the artificially cyclophosphamide formed immunodeficient state may be used as an experimental model for further investigation of the biological alterations responsible for angiomatosis. On the other hand, we believe that this new method will enhance the diagnostic sensitivity and specificity needed to achieve a diagnosis of bartonellosis.
