ROLE UF HISTAMINE IN THE MECHANISM OF ALLERGIC REACTIONS (Russian text) -Ado A.D. Moscow - PATOL.FIZIOL. I EKSPE It. TERAP. 1957, 1/2 (12-IT~ Report on experimental data about the mutual relationship of noradrenaline, acetyl- tholine and histamine in development of anaphylactic shock and allergic reactions in various organs. On the basis of established facts a hypothesis is put forward that histamine is not a universal intermediary link - an anaphylotoxin in the mechanism of the various functional manifestations of allergic reactions. This is indicated by the fact that allergic reactions in many organs (lingual vessels in the dog, small intestine of guinea-pig, skeletal muscles of dog, rabbit, hen and goose) are not associated with histamine secretion. The anti-histamine preparation diphenhydra- mine does not alter the intensity of allergic reactions in these organs. It was es- tablished that in the early stages of development (before the 5th-6th day) of serum allergy the procenst involves sympatho-eruic innervation mechanisms (noradrena- line increases in the blood o1 dogs) and later on the cholinergic ones. At a later period, about 2-3 weeks from the start of sensitization of the animals, allergen causes histamine liberation in all organs; this is the expression of the 2nd and less specific phase in the development of the allergic reaction - phase of alterations with powerful histaminergic reactions (picture of anaphylactic shock). A hypothesia in put forward that in allergy there are multipie ways in which disturbances of innervation can occur. This is contrary to the accepted view that there is a single substrate and a singl,t internal mechanism in both the generalized and local allergic reactions. References: 21.

For sensitization, 0.3 ml were given subcutaneously i and the anaphylactic injection was given Intravenously after 28-33 days.~ Desensitization was given every 2 hours until complete arrest of the reaction. The desensitizBrs were suspensions of normal brain, 2 or 4 UDC: 615-372 : 576.858.257-o11 ACC NRt AP6001j.567 3ays' vaccine, and culture-der ived fo:?malin inactivated vaccine against 'Uhe above disease. Sensitization of -Vhe guinea pigs with a suspension Df healthy mouse brain tissue caused only weak anaphylactic reaction ipon subsequant introduction of the some suspension. Sensitization with vaccine from brain of mice without clinical siEns of the discase caused 5tron,g anaphylactic reaction; so did vaccine from sick mice. The snaphylactic reaction in guinea pigs sensitized with the 2-day vaccine 3ould be inhibited by prior two-fold desensitization with either normal orain suspension or vaccine, in contrast to 4-day vaccine where such desensitization did not inhibit anaphylactic reaction, due apparently to the large amount of intermediate antigens present in the 4-day vaccine, It may be concluded that intermediate antigens start appearing on the 3econd day after infection and that they increase during virus tultiplication in the mouse brain.

The theoretically computed curves of the energy distribution in the spectrum of the radiation of electrons with 150; 225 and 250 KeV are compared in a diaCram with the correspondin,rf experimental values, The intensity distributions obtained at certain electron energies confirm theoretical conclusions within the limits of measuring errors. The observed systematic deviation of experimental points within the range of short waves (even though it does not exceed the limit of measuring errors) is apparently due to the !over de.-ree of accuracy of the gauging of the spectral sensitivity of the apparatus within this range.

TITLEs Coherent radiation of electrons in a synchrotron PERIODICALt Atomnaya energiya, v. 9, no. 6, 196o, 455-46o TEXTt An electron orbiting in a synchrotron will radiate electromagnetic waves with a frequency that is equal to a multiple of the rotational frequency. In a wave range comparable to the dimensions of the cluster this radiation will be coherent and a function of the orbital distribu- tions of the electrons. This is taken into account in the equation of the intensity for coherent radiation by introducing a form factor F nm . The authors have determined experimentally the coherent radiation of the electrons in a synchrotron at I - 10 cm (which corresponds to the 50th harmonic of the rotational frequency) for various electron distributions within the "separatrizes". Fig. I shows a block diagram of the unit used. A superheterodyne receiver was employed for the radiation pickup. The horn antenna (1) and the mixer (2) were located very close to the accelerator; the heterodyne (9) with a K-11 (K-11) klystron, the inter- Card 1/A5,L/. 22-44 2 S/089/60/009/006/002/011 Coherent radiation of ...

The intermediate-frequency amplifier was a six stage tuned 5 amplifier having a 0-5 MG pass band and an amplification factor of ,5.10 The intermediate frequency was chosen to 25 Me. After detection the signal was fed to the oscilloscope (5) of the type OK-17M (OK-17M). The signal frequency of the klystron was varied by changing the potential at the refleotor by means of the selsyns (6) and (7), The results of these investigations have been illustrated graphically,. FiF,. 2 shows the dependence of the relative number of particles captured in the accelera- tion systew of the synchrotron, counted from the instant of turning on the h-f accelerating field. The optimum instant corresponds to an N-100. In I and III the electron distribution is nearly a 6-function with respect to the amplitudes of the phase oscillations and in 3ection :_21 II it is nearly equal to f Y(2f The oscillograms 2!P0 0 [Abstracter's notei cannot ~e reproduced] show that no radiation will occur during the betatron type operation up to E,S4 Mev; it will occur card 2Aq Coherent radiation of ... b '/ - B10213212 after a cluster has formed., The radiation intensity will drop rapidly for E> 180 Mev and will be smaller than the noise level.

Slow intensity 'oscillations are caused by an adiabatic da.-.1ping of the phase oscillations, 1'easuring the pass band of the'50th harmonic resulted in a value of 4-0.5 Mc. 'The strong intensity drop.at electron energies above 160 Ylev may be explained by a subsequent Gaussian distribution of- the electrons with respect to the phase oscillation amplitudes.

This low energy radiation can be absorbed in materials of low atomic number for which the ratio of cross- section for Compton effect to pair formation is sufficiently great. The most favourable material for use as an absorber is LiH. A filter was constructed i-.,hich consisted of a duralumin tube 2 m long and 28 mm bore filled with LiH and the ends hermetically scaled with duralumin caps 0.5 111:,' thick. By using crushed Lili crystals a packing coefficient of 601"0 was obtained and the length of the filter was then equal to 1.06 radiation lengths of 105 g/cM2. Analysis showed that the LiH contained 12'1o' UOH, which was allowed for when calculating its transmission. The Card 1/2
