Nn-9 was a non-crystalline alkaloid isolated from the embryo of the seeds of the Asiatic lotus, Nelumbo nucifera. In anesthetized cats, iv.injections of 1—2 mg/kg lowered, after a delay of 1/2—1 minute, the blood pressure by about 50% from the original level, lasting 2—3 hours. In dogs, the blood pressure returned to normal in 1/2 hour. This dosage was ineffective in rabbits. Tachyphylaxis developed on repeated administrations. After the cats were pretreated with Diphenhydramine or Promethazine, the hypotensive...

Nn-9 was a non-crystalline alkaloid isolated from the embryo of the seeds of the Asiatic lotus, Nelumbo nucifera. In anesthetized cats, iv.injections of 1—2 mg/kg lowered, after a delay of 1/2—1 minute, the blood pressure by about 50% from the original level, lasting 2—3 hours. In dogs, the blood pressure returned to normal in 1/2 hour. This dosage was ineffective in rabbits. Tachyphylaxis developed on repeated administrations. After the cats were pretreated with Diphenhydramine or Promethazine, the hypotensive effect of Nn-9 was remarkably diminished. Pretreatment with Nn-9 also lessened the hypotensive action of histamine. When the cats were given 2 mg/kg of Nn-9 intravenously, the hypotension was accompanied by a reduction of cerebral vascular resistance. Intra-arterial injections yielded an increase of both cerebral and femoral blood flows, associated with a diminution of the vascular resistance. In spinal cats, i.v. injection of 2 mg/kg produced a significant drop of blood pressure. The pressor responses elicited by i.v. adrenalin, noradrenalin, pituitrin, or by spinal compression below C-7 were all inhibited for 1/2—1 hour. The retraction of nictitating membrane by preganglionic faradization was also inhibited. But it had no apparent influence on parasympathetic ganglion and M-cholinergic reactive system. Intracarotid injections produced a hypotension, together with a decrease of the carotid occlusion reflex pressor response. In conclusion, Nn-9 seems to act primarily through histamine release. Secondarily, a nervous factor is also involved.

蓮子心非結晶生物碱Nn-9对麻醉猫靜脉注射1-2毫克/公斤可降低原血压水平約50%,維持2-3小时。狗血压于1/2小时卽恢复,兔子不降压。有快速耐受性。經苯海拉明及异丙嗪处理猫再注射Nn-9碱2—3.5毫克/公斤,降压作用明显減弱。对靜脉注射組織胺引起的降压被Nn-9所減弱。猫靜脉注射2毫克/公斤的Nn-9后,血压下降伴随脑血管阻力減低,动脉注射0.2毫克/公斤使脑血流及后肢血流均增加,血管阻力減低。脊猫靜脉注射2毫克/公斤,有明显的降压出现。靜脉注射腎上腺素、去甲腎上腺素及脑垂体后叶素或在第七頸椎以下加高脊髓腔压所引起的升压反应均被抑制,历1/2—1小时恢复。电刺激頸交感神經节节前纤維所致的瞬膜收縮也受到抑制。对副交感神經节及M-胆碱反应系統无明显影响。頸动脉注射药液也出现降压,并抑制頸总动脉血流阻断所引起的升压反应。总結实驗結果,Nn-9的降压机制主要是释放組織胺,使外周血管扩张,其次神經因素也有关。

A new approximate method for treating nn and pp pairing force in nuclei is presented. In this method the difficulties connected with the application of BCS-Bogolubov method to nuclei such as the non-conservation of the number of particles, the apperance of spurious states, and non-orthogonality between wave functions of different excited states are avoided. But the method can be conviently adopted only when the number of particles n and the number of levels Ω considered are small (n ≤10, Ω≤10 ). Also the...

A new approximate method for treating nn and pp pairing force in nuclei is presented. In this method the difficulties connected with the application of BCS-Bogolubov method to nuclei such as the non-conservation of the number of particles, the apperance of spurious states, and non-orthogonality between wave functions of different excited states are avoided. But the method can be conviently adopted only when the number of particles n and the number of levels Ω considered are small (n ≤10, Ω≤10 ). Also the approximation of this method is good onlv under such conditions. In this method the many-body nature of the excitation is displayed explicitly without introducing the conception of quasi-particles. The excitation of the system can be divided into two classes. The first class of excitation is a kind of single particle excitation embedded in a many-body system under the action of the pairing force. This would correspond to the excitation of a single quasi-particle a_v~+av0 or to two quasi-particle excitation of the type α_v~+β_(v')~+,α_v~+α_v'~+(v'±v) etc. in the BCS-Bogolubov method. The second class of excitation is a pair excitation in which the distribution of the conjugated pairs of particles among the levels is altered. This type of excitation would correspond to superposition of quasi-particle excitations of the type α_v~+β_v~+,α_v~+β_v~+α_μ~+β_μ~+, Also examined is the effect of pairing force on the β- and γ-transition probability in the new formalism. In general, β-transition is retarded by the pairing force while in γ-transition the effect of pairing force varies according to the nature of the relative excitation between the initial and final states. When the relative excitation is of the first class, the transition is retarded to various extent, depending on the nature of the γ-transition. If the relative excitation is of the second class, the transition is forbidden when the pairing force is not in action, and is allowed only for electric transition arising from the charge-current distribution when the pairing force is present. Finally this method is applied to investigate the effect of pairing force on the intrinsic spectra and β-transition in 72Hf178 as an example.

本文提出了一个处理原子核中nn及pp对力的近似方法。这个方法避免了通常将方法应用于原子核所引起的困难,例如粒子数不守恒,假态的出现以及不同激发态波函数不正交等。但这个方法只有在所需考虑的粒子数n及能级数Ω不太大时(n≤10,Ω≤10)才能较方便地被应用,近似程度才比较好。在这个方法中,毋须引入准粒子的概念,激发的多体性质被明显地表示出来。系统的激发可分为两大类型。第一类型激发是一种以多体系为背景的单粒子跃迁,相应于一个准粒子的跃迁α_ν~+α_ν,或两个准粒子的激发α_v~+β_v′~+,α_v~+α_v′~+(vv′)。第二类型激发是对激发,在这种激发中,各能级上共轭粒子对的填充几率改变了,相应于共轭的准粒子对的激发α_v~+β_v~+,α_v~+β_v~+α_μ~+β_μ~+,…. 本文还考察了对力在r及β跃迁中的影响。在β跃迁中,对力一般是使跃迁受阻。在r跃迁中,对力的效应随初末态间的相对激发类型不同而异,如相对激发属于第一类型,则跃迁受阻,受阻程度随跃迁的电磁性质不同而有所差别,如相对跃迁属于第二类型,则在无对力作用时跃迁是禁戒的,在对力作用下也只有由电荷电流所产生的电跃迁是允许的。 最后本文以Hf~...

A new concept, the "energetic parameter of solution", is suggested for molten salt solutions. For the A_n B_m—A_n' C_m' system (valency of A ion is Z):f(r)=(Z~2nn')/(m(r_A+r_B))+(Z~2n'~2)/(m'(r_A+r_C))-(2Z~2nn')/(2r_A+r_B+r_C)(n'/nm'+1/m)n>n'. For A_nB_m—C_n'D_m' system (valency of C ion is Z'): f(r)=(n'Z'Z((n+nZ)/(n'Z')m'))/(m'(r_A+r_D))+nZZ'(m+nZ/Z')/(m(r_B+r_C))-(nZ~3(n+m))/(m(r_A+r_B))-(n'Z'Z(n'+m'))/(m'(r_C+r_D)).

A new concept, the "energetic parameter of solution", is suggested for molten salt solutions. For the A_n B_m—A_n' C_m' system (valency of A ion is Z):f(r)=(Z~2nn')/(m(r_A+r_B))+(Z~2n'~2)/(m'(r_A+r_C))-(2Z~2nn')/(2r_A+r_B+r_C)(n'/nm'+1/m)n>n'. For A_nB_m—C_n'D_m' system (valency of C ion is Z'): f(r)=(n'Z'Z((n+nZ)/(n'Z')m'))/(m'(r_A+r_D))+nZZ'(m+nZ/Z')/(m(r_B+r_C))-(nZ~3(n+m))/(m(r_A+r_B))-(n'Z'Z(n'+m'))/(m'(r_C+r_D)). The "energetic parameter of solution" is an approximate function of electrostatic energy of mixing of molten salts. When f(r) is positive, the solution exhibits negative deviation; when f(r) is negative, the solution shows positive deviation. The function f(r) may be used as an approximate method to estimate the thermodynamic properties of molten salt solutions, as well as phase diagrams of binary salt systems.

提出了熔盐溶液的溶解能参数的概念,熔盐系A_nB_m-A_(n′)C_(m′)(A离子之价数为Z)的溶解能参数为: f(r)=Z~2nn′/m(r_A+r_B)+Z~2n′~2/m′(r_A+r_C)-2Z~2nn′/(2r_A+r_B+r_C)(n′/nm′+1/m) 熔盐系A_nB_m-C_(n′)D_(m′)(C离子之价数为Z′)的溶解能参数为: f(r)=n′Z′Z(n+(nZ/n′Z′)m′/m′(r_A+r_D)+nZZ′(m+nZ/Z′)/m(r_B+r_C)-nZ~2(n+m)/m(r_A+r_B)-n′Z′Z(n′+m′)/m′(r_C+r_D)。溶解能参数是熔盐静电混合能的近似函数,当f(r)为正值时,溶液呈现负偏差,当f(r)为负值时,溶液呈现正偏差,f(r)可作为估计熔盐溶液的热力学性质和二元熔盐相图的近似方法。
