On analysing the biological data of the recent years,a hypothesis of chromosomal sectional activity has been produced which manifested as:(1)During the individual development,the chromosome proceed its sectional activity regularly with its different components.(2)The sectional activity is uninverseable and the specificity is proved gradually in the individual development.The activationer of the activity is found to be the hormone and the suppressor histone.(3)Chromosome is a sort of essential genetic material,but...

On analysing the biological data of the recent years,a hypothesis of chromosomal sectional activity has been produced which manifested as:(1)During the individual development,the chromosome proceed its sectional activity regularly with its different components.(2)The sectional activity is uninverseable and the specificity is proved gradually in the individual development.The activationer of the activity is found to be the hormone and the suppressor histone.(3)Chromosome is a sort of essential genetic material,but far from the doctrine of Mendel-Morgan's chromatophore of gene.This was confirmed by the sectional activity of chromosomal component was not in accordance with the proceedings of the character differentiation.The activity of the chromosome has provided with different material basis and the processes for the character differentiation.Lastly,by applying the hypothesis,it is hoped to render some new explanations to the principles of Mendelian genetics,the matrilineal inheritance,the corresponting stage inheritance as well as in the cases concerning cancers.

根据近年来有关的理论及实验资料,对染色体在遗传发育中的活动规律进行了分析,提出一个染色体阶段活动假说。认为染色体不是与性状一一对应的基因的载体,染色体上遗传单位的活动与性状分化不是一回事。在个体发育中染色体是以不同组份(或单位),循序进行着不同质的阶段活动,从而控制着性状分化的程序。并根据这个假说对遗传、发育、癌等提出了新的解释,以说明它对生物学理论与实践的意义。

Rabbits were operated with an initial dose of light chloralose-urethane anes-thesia,and then immobilized by Flaxedil.Extracellular recordings were madefrom medial reticular units of the midbrain by KCl—K_3Fe(CN)_6 filled micropi-pettes.Four types of somatosensory units can be identified according to theirdischarge pattern and threshold to peripheral nerve stimulation.They are highthreshold excitatory(HTE),high threshold inhibitory(HTI),low threshold exci-tatory(LTE)and low threshold inhibitory(LTI)units.The effects of tetanization of preoptic-anterior hypothalamic(PO-AH)areaon three types(HTE,HTI,LTI)of these units were studied.Among the 31HTE units 16 were responsive to PO-AH tetanization,9 of which showed an in-hibitory effect,that was sometimes quite prolonged.Other units showed excita-tory,or excitato-inhibitory effects.However,the basal discharges behaved some-what differently,among 31‘pain’units 18 were affected,in which 10 showedexcitatory effect;6 inhibitory;2 excitato-inhibitory.All of the 5 HTI units showed enhancement of inhibition on tetanization ofPO-AH.Of the 17 LTI units,6 showed inhibitory effect,5 excitatory;1 excitato-inhibi-tory,while the remaining units were unresponsive to PO-AH tetanization.Theabove-mentioned results showed a preponderance of inhibitory effects of PO-AH stimulation on the medial reticular units.The following points were discussed:(1)the‘pain’units in medial reticularformation of the midbrain;(2)the relation of PO-AH stimulation to analgesia andacupuncture analgesia;(3)the relation of PO-AH stimulation to modulation ofsensory transmission.

家兔在氯醛糖-尿酯浅麻醉下手术,然后用三碘季胺酚制动。用玻璃微电极寻找中脑内侧网状结构对腓肠神经不同强度的刺激有反应的各种躯体感觉单位。对其中三类单位的活动及强直刺激视前区-下丘脑前部(PO-AH)对它们的影响作了分析。这三类单位是:高阈体感兴奋单位,即“痛”单位,高阈体感抑制单位和低阈体感抑制单位。对一些“痛”单位的位置作了组织学检查。实验结果表明:有16/31的“痛”单位放电受 PO-AH 强直电刺激的影响。在受影响的16个“痛”单位中,呈抑制效应的9个。这种抑制效应有时具有较长的后作用。18/31的“痛”单位的基础放电受 PO-AH 的影响,其中兴奋的10个。电刺激 PO-AH 对5个高阈体感抑制单位均呈加强抑制的效应,对17个低阈抑制单位的影响,也以抑制的居多数。PO-AH 对三类体感单位还有兴奋、兴奋-抑制效应。本文实验结果讨论了:(1)中脑内侧网状结构的“痛”单位。(2)PO-AH 与镇痛及针刺镇痛的关系。(3)PO-AH 对感觉功能的调制。

It is well known that systemic administration of morphine results in a depres-sion of respiration and cough reflex.Its mechanism has been considered to in-volve a depression of the brain stem respiratory neurones.But,few direct eviden-ces were available until recently Denavit-Saubié et al.demonstrated in cat thateither morphine or methionine-enkephalin was able to depress the activities ofthe brain stem respiratory neurones.In the present study,we observed the ef-fects of morphine applied microiontophoretically on respiratory as well as non-respiratory neurones in the region of the solitary tract at the level of obex.Experiments were carried out on 29 rabbits.Animals were anaesthetizedwith urethane(1 g/kg i.v.)in most cases,but a few experiments were performedon paralysed conscious rabbits.Procaine was infiltrated wherever skin incisionwas made.The animals were then immobilized with gallamine triethiodide andventilation was maintained by a respirator pump.Five-barrel glass micropipet-tes were used to record the extracellular activity and to iontophorese the drugions.A medical data processing computer was used on line to generate the spikefrequency histograms.The effects of morphine given iontophoretically on theunit discharge rate were examined.Of the 61 respiratory units recorded,6 wereexcited and the remainder were not influenced.Neither the spontaneous ac-tivity nor the glutamate-induced excitation of the respiratory units was seen to bedepressed by iontophoretic application of morphine.On the other hand,whileapplied on 49 non-respiratory units,morphine depressed 19,excited 3 and hadno effect on the remaining 27 units.Naloxone administered iontophoreticallyblocked morphine-induced depression six out Of fourteen times,but did not blockmorphine-induced excitation in our experiments.Our results indicate that the respiratory neurones in the region of the solitarytract are less sensitive to morphine and glutamate than the non-respiratory neu-rones in the same area.It is probable that in rabbit the depression of the respira-tory neurones in the region of the solitary tract by systemic morphine is broughtabout through an indirect way.

用五管微电极在家兔延髓孤束区记录单位活动并观察微电泳给予吗啡时对单位活动的影响。在61个呼吸性单位中,吗啡引起兴奋的单位有6个,其余55个活动无明显改变。没有看到吗啡引起明显阻遏的单位。在49个非呼吸性单位中,吗啡引起阻遏的有19个,兴奋的3个,其余27个活动无明显改变。在吗啡引起阻遏的单位中,有43%的单位吗啡效应可被纳洛酮对抗。没有看到纳洛酮能对抗吗啡的兴奋效应。上述结果表明家兔延髓孤束区中的呼吸性单位对吗啡和谷氨酸的敏感性比同一区域内的非呼吸性单位低。静脉内注射吗啡所引起的呼吸抑制效应并不是吗啡对该区域内呼吸性神经元的直接作用。
