摘要： Macropterous females of Pyrrhocoris apterus (L.) reared under short-day conditions (LD 12:12 h) were analysed for temporal patterns of feeding and drinking behaviour, activities of digestive enzymes in the gut, and lipid and glycogen content in the haemolymph and fat body. Peaks of drinking activity were recorded at days 3, 7 and 10 during the first 14 days after imaginal ecdysis, Feeding activity peaked on the third day, ceasing completely after the fourth day of adult life. Esterase, protease, amylase and aminopeptidase activities exhibited the highest overall activity in the first days after imaginal emergence;then enzyme activities decreased. In the fat body, the content of lipids was highest on day 5, then a decrease of about 40% was observed at day 14;the amount of glycogen was highest on day 1 at 11 mu g of glucose equivalents/mg of fat body, then decreased to 2 mu g at day 14 after the imaginal moult. In the haemolymph, the lipid content rose until day 8 when it reached almost 0.3 mu mol/mu l;at day 14 the value was slightly lower. The association of fasting with reproductive arrest in macropterous females of P. apterus, accompanied by a decrease in digestive enzyme activities and a mobilization of lipid reserves from the fat body, was demonstrated.

摘要： Clinical neurophysiologic studies have an important role in the diagnosis and management of the patient with epilepsy. Epilepsy is a clinical diagnosis and the EEG is an important adjunct used to differentiate epileptic seizures from nonepileptic events, refine the diagnosis of epilepsy into specific seizure types and epileptic syndromes, and provide a measure of brain function. The value of the EEG is highly dependent on the clinical context in which it is being applied. In some epilepsies the interictal EEG may he diagnostic whereas in others an ictal recording may be necessary to obtain a specific diagnosis. Both the interictal and ictal EEG characteristics vary with specific seizure types and epilepsies and are described in detail in this review. The usefulness of the EEG in the management of epilepsy and in aiding in the decision to discontinue antiepileptic therapy is also discussed.

摘要： Aims/background-The basis of binocular single vision in microtropia remains a matter of contention. This paper discusses the implications of recovery, in a group of primary microtropes following treatment, in relation to current concepts on the aetiology of the condition and proposed retinocortical correspondence. Methods-Nine previously untreated primary microtropes whose condition resolved, were reviewed in detail to assess the patterns of change in retinal correspondence, uniocular fixation, stereoacuity, and visual acuity in response to treatment. Results-Anomalous retinal correspondence (ARC), a central scotoma, reduced or absent stereoacuity, amblyopia, and uniocular eccentric fixation were present in all patients before treatment. Following treatment, all cases attained normal retinal correspondence (NRC), elimination of the central scotoma, stereo acuity levels of between 20 and 40 seconds of arc, 6/5 Snellen visual acuity in both eyes, and foveal fixation in both eyes. Conclusion-A hypothesis is put forward that for the patients described, a period of normal development is likely to have preceded the onset of microtropia, during which the retinocortical "foundations" for NRC were established. Precise pairing of foveo-foveal receptive fields was not abolished by the presence of amblyopia and a central scotoma, but this relation was temporarily suspended and binocular single vision was sustained via the neural substrate of paired receptive fields over a wide retinocortical area.

摘要： 为探讨人对视动刺激心理、生理反应的特征，给３０名男性军校学员一系列阶跃视动刺激（５、１０、１５、２０、３０、４０、６０、８０、１００及１２０°／ｓ），每个刺激持续２０ｓ。用磁带机记录被试的视动性眼震信号及视动性错觉出现的潜伏期和错觉量。用７Ｔ１７信息处理仪采样处理视动性眼震信号，用模糊集途径量化错觉量。结果：（１）视动性眼震的快相速度和慢相速度均随刺激速度增加而增大，在６０°／ｓ范围达到峰值，在６０～１２０°／ｓ范围内基本维持稳定状态；（２）在５～１２０°／ｓ内，视动性错觉随刺激速度的增加而增大，呈直线上升。结论：视动性眼震与视动性错觉是视动刺激引起的生理和心理两方面的反应，各自表现不同的变化趋势。

摘要： 对国外近年来有关南极人体生理学和心理学的部分研究资料作了简述。研究者们普遍认为，南极特殊的自然和社会环境可引起人体血压、心率、体温、体重、免疫功能、睡眠、生物节律和心理活动等方面的变化。人体对这种环境有一定的适应能力。南极环境对考察队员的心理产生不同程度的应激刺激。在考察人员的选拔工作中，特别需要注重效度（尤其是预测效度）的检验。以上资料为进一步开展南极人体医学考察提供了依据。

摘要： 现代世界各发达国家都在大力研究"从零开始"的家庭教育问题。据现代神经生理学的研究表明,人的智能增长是遵循"递减原则"的。这一法则正是"从零开始"进行家庭教育的重要理论基础。音乐,是"从零开始"教育中至关重要的一项内容。"音乐是儿童的天使",孩子在生活、生长和发展中不能没有音乐。人民音乐家冼星海说:"音乐,是人生最大的快乐;音乐,是生活中的一股清泉;音乐。
