The effect of collagen degradation products (CDP I--molecular weight circa 3000 D and CDP II--molecular weight circa 1200 D) on the central dopaminergic system was studied. Differences in the action of both these fractions in the apomorphine stereotypy test were noted; CDP I administered to rats in a dose of 5 micrograms just before application of the drug inducing the stereotypy enhanced the stereotypic behaviour of the animals whereas a dose of 40 micrograms significantly inhibited such behaviour. CDP II, on the other hand, had no effect on this type of stereotypy. Both fractions given in doses of 15 and 40 micrograms enhanced the stereotypy induced by amphetamine. CDP I and CDP II (15 and 40 micrograms) administered 30 min before observation of the animals intensified the cataleptic action of haloperidol, whereas both fractions (CDP I and CDP II) when administered 45 min before observation reduced the catalepsy.

研究了胶原降解产物(分子量约为3000 D的CDP I和分子量约为1200 D的CDP II)对中枢多巴胺能系统的影响。注意到这两部分在阿吗啡刻板印象试验中的作用差异;在使用诱导刻板印象的药物之前,给大鼠5微克的CDP I增强了动物的刻板印象行为,而40微克的剂量则显著抑制了这种行为。另一方面,方案二对这种陈规定型没有影响。剂量分别为15微克和40微克的两部分都增强了安非他明引起的刻板印象。在观察前30分钟给药的CDP I和CDP II(15和40微克)能增强氟哌啶醇的催化作用,而在观察前45分钟给药的CDP I和CDP II组分均能减轻氟哌啶醇的催化作用。

The effect of disodium cromoglycate on the skin wound healing and collagen content in the wounds of rats. 甘糖酸二钠对大鼠皮肤创面愈合及胶原蛋白含量的影响。
Pub Date : 1990-01-01
R Dabrowski, J Drobnik

The effect of disodium cromoglycate on skin wound healing and collagen formation in the wounds was studied. Disodium cromoglycate (a mast cell stabilizer) administered to the rats in a dose of 2 mg/animal was found to retard wound healing and markedly increased wound surface in all examined days (3rd, 5th, 7th, 10th, 14th day of healing). The mast cell stabilizer injected directly into wounds decreased collagen content, especially on 10th and 14th day of the healing process.

研究了甘露糖酸二钠对皮肤创面愈合及创面胶原形成的影响。以2 mg/只的剂量给药大鼠的肥大细胞稳定剂克罗甘酸二钠,在愈合后的第3、5、7、10、14天均能延缓创面愈合,并显著增加创面面积。创面直接注射肥大细胞稳定剂可降低胶原蛋白含量,尤其是在创面愈合第10天和第14天。

The central effects of pancreatic glucagon and insulin given intracerebroventriculary (i.c.v.) upon sympathetic activity in the cervical trunk and adrenal nerve were examined in Wistar Kyoto rats. Glucagon i.c.v. administration led to an increase in sympathetic nerve activity in both nerves. Insulin injected into lateral ventricle caused opposite to glucagon inhibitory influence on sympathetic discharge in the cervical trunk and adrenal nerve. This two different central effects of glucagon and insulin on sympatho-adrenal system may contribute to glycemia homesthasis.

The effect of an alerting acoustic stimulus on the heart rate, sympathetic activity and aortic baroreceptor discharge in conscious rabbits before and after naloxone administration. 纳洛酮对清醒家兔心率、交感神经活动和主动脉压力感受器放电的影响。

Blood pressure, heart rate, aortic nerve activity and cervical sympathetic discharge were recorded simultaneously in 10 rabbits. Chronic recordings were made with electrodes implanted to the uncut aortic and cervical sympathetic nerves. 1. The alerting acoustic stimulus produced a short lasting decrease in sympathetic activity with a transient bradycardia. 2. In 6 out of 8 rabbits i.v. administration of naloxone chloride (100 mg/kg) diminished or abolished early inhibitory effects evoked by acoustic stimulus. 3. The sympatho-inhibitory system involved in the startling response appears to be independent of the baroreceptor inhibitory reflex and has opposite responsiveness to naloxone. 4. A decrease in efferent sympathetic activity with no accompanying change in the aortic nerve activity suggests some central resetting of the baroreceptor-sympatho-inhibitory reflex. 5. We suggest that the observed autonomic effects following an alerting stimulus are typical for a fear-anxiety drive.

同时记录10只家兔的血压、心率、主动脉神经活动和颈交感放电。将电极植入未切开的主动脉和颈交感神经,进行慢性记录。1. 警报性的声音刺激产生短暂的持续的交感神经活动减少,并伴有短暂的心动过缓。2. 8只家兔中,有6只家兔静脉注射氯纳洛酮(100mg /kg)可减弱或消除声刺激引起的早期抑制作用。3.参与吃惊反应的交感抑制系统似乎独立于压力感受器抑制反射,对纳洛酮有相反的反应。4. 传出交感神经活动减少,而主动脉神经活动无变化,提示中枢压力感受器-交感-抑制性反射复位。5. 我们认为,观察到的警觉刺激后的自主神经效应是典型的恐惧-焦虑驱动。

Antipyretic activity of prazosin. 哌唑嗪的解热活性。
Pub Date : 1990-01-01
Z Szreder

Thermal responses to prazosin (0.75 mg/kg, i.v. as a bolus injection or 3 h infusion) were investigated in febrile rabbits (treated with E. coli lipopolysaccharide, PLPS) at 3 ambient temperatures (Ta) of 5, 19, 28 degrees C. The drug produced antipyresis which increased with the simultaneous drop of Ta. This antipyretic activity was accompanied by an inhibition of heat production or enhanced elimination of heat, depending on Ta. It is suggested that antipyresis produced by prazosin is mainly due to the effector part of the thermoregulatory system.

Interaction between the sarcoplasmic reticulum and mitochondria in the control of contractile calcium in guinea-pig atria--does it exist? 肌浆网和线粒体在控制豚鼠心房收缩钙中的相互作用——是否存在?
Pub Date : 1990-01-01
A Prokopczuk

The inhibitory action of caffeine on calcium (Ca2+) release from the sarcoplasmic reticulum (SR) and interference with mitochondrial (Ca2+) fluxes by a mitochondrial uncoupler protonfore CCCP were utilized to define a calcium pool responsible for potentiation of post-rest twitch tension in guinea-pig atria. The Ca2+ fluxes were assessed by means of 45Ca2+. Caffeine and CCCP when applied separately did not affect post-rat 45Ca2+ content. Yet, when they were applied together it was markedly reduced to the resting level. It is concluded that a possible source of contractile Ca2+ may be located in mitochondria and an eventual shift of Ca2+ between mitochondria and the SR seems to be a plausible assumption.

咖啡因对肌浆网(SR)钙(Ca2+)释放的抑制作用和线粒体解偶联蛋白CCCP对线粒体(Ca2+)通量的干扰作用被用来确定一个钙池,该钙池负责增强豚鼠心房休息后抽搐张力。通过45Ca2+测定Ca2+通量。单独施用咖啡因和CCCP时,不影响大鼠后45Ca2+含量。然而,当它们一起使用时,它显着降低到静息水平。这是结论,一个可能的来源的收缩Ca2+可能位于线粒体和Ca2+的最终转移之间的线粒体和SR似乎是一个合理的假设。

Motor nucleus of the V-th nerve and the control of breathing (Breuer-Hering reflexes and apneustic breathing). 第五神经的运动核与呼吸的控制(布鲁尔-赫林反射和窒息性呼吸)。
Pub Date : 1990-01-01
H Gromysz, W A Karczewski, U Jernajczyk

Earlier studies from this department have demonstrated that neurones of the V-th nerve motor nucleus (NVmt) have oligosynaptic, inhibitory output to the inspiratory motoneurone pool being themselves under the influence of a polisynaptic input from vagal afferents. To check the hypothesis that NVmt is a part of the pneumotaxic mechanism, we studied the effects of pharmacological mictroblockade of the NVmt on Breuer-Hering reflexes in halothane-anaesthetized, paralyzed and artificially ventilated rabbits. Activities of NVmt neurones and phrenic nerve firing were recorded. Acid-base balance was controlled and histologic examinations were routinely performed. Expiratory activities were regularly found in NVmt. Its blockade elicited a typical apneustic breathing. During the blockade the Breuer-Hering reflexes gave "paradoxical" effects: an increase in central respiratory frequency following inflation, inspiratory apneusis in response to deflation. We conclude that the NVmt is an important component of the pneumotaxic mechanism or even the anatomical substrate of the pneumotaxic "centre".

该系的早期研究表明,V-th神经运动核(NVmt)的神经元在迷走神经传入的多突触输入的影响下,对吸气运动神经元池具有少突触的抑制输出。为了验证NVmt参与肺致死机制的假设,我们研究了NVmt药理微阻断对氟烷麻醉、麻痹和人工通气家兔布鲁尔-赫令反射的影响。记录NVmt神经元活动和膈神经放电。控制酸碱平衡,常规进行组织学检查。NVmt有规律地发现呼吸活动。它的封锁引起了典型的窒息性呼吸。在封锁期间,布鲁尔-赫林反射产生了“矛盾”的效果:通货膨胀后中央呼吸频率增加,通货紧缩时吸气性呼吸暂停。我们得出结论,NVmt是肺滑行机制的重要组成部分,甚至是肺滑行“中心”的解剖基底。
