چکیده
Rats were immunized ( 1 ) with Jensen rat sarcoma tissue; ( 2 ) with emulsions of normal rat spleen; ( 3 ) with normal rat blood. Sera from rats of these three series were tested against ( a ) cultures of Jensen rat sarcoma cells; ( b ) cultures of normal spleen cells; (c) cultures of mouse carcinoma 63; ( d ) cultures of cells of normal mouse spleen. Jensen Rat Sarcoma Tissue as Antigen: Two series of '( tumour-resistant " rats were employed. ( 1 ) Rats of the Jensen rat sarcoma susceptible strain of the Imperial Cancer Research Fund Laboratories. These rats had been used for routine transplantation of the Jensen rat sarcoma; the implants had grown for a time and had then regressed. ( 2 ) Rats of the Wistar strain in which the Jensen rat sarcoma cells do not flourish readily. Twelve such rats were given routine inoculations with minced Jensen rat sarcoma. Of these, 9 showed transient growth of a tumour; one produced a good tumour of progressive growth which was subsequently used for further transplantation; two rats died, one after a small growth had entirely regressed. Two series each of six rats were selected for immunization with Jensen rat sarcoma. One series consisted of resistant rats of the J.R.S. susceptible strain arid one of Wistar rats which had been given a test inoculation. All these rats were given intraperitoneal injections of 1 C.C. of minced J.R.S. weekly. Normal Spleen as Antigen: A series of 6 normal Wistar rats were similarly injected weekly with doses of 1 C.C. of minced spleen obtained from normal rats of various strains. Normal Blood as Antigen: Six Balogh rats were injected weekly with 1 C.C. each of citrated whole blood from normal rats, usually the same rats as were used to provide spleen tissue.

Next blasthole pattern were designed based on previous blasting results. The results of the...
متن کاملA NORM INEQUALITY FOR CHEBYSHEV CENTRES
In this paper, we study the Chebyshev centres of bounded subsets of normed spaces and obtain a norm inequality for relative centres. In particular, we prove that if T is a remotal subset of an inner product space H, and F is a star-shaped set at a relative Chebyshev centre c of T with respect to F, then llx - qT (x)1I2 2 Ilx-cll2 + Ilc-qT (c) 112 x E F, where qT : F + T is any choice functi...
متن کاملRepresentation of $H$-closed monoreflections in archimedean $ell$-groups with weak unit
The category of the title is called $mathcal{W}$. This has all free objects $F(I)$ ($I$ a set). For an object class $mathcal{A}$, $Hmathcal{A}$ consists of all homomorphic images of $mathcal{A}$-objects. This note continues the study of the $H$-closed monoreflections $(mathcal{R}, r)$ (meaning $Hmathcal{R} = mathcal{R}$), about which we show ({em inter alia}): $A in mathcal{A}$ if and only if...
متن کاملA NOTE ON THE EQUISEPARABLE TREES
Let T be a tree and n_{l}(eIT) and n_{2}(eIT) denote the number of vertices of T, lying on the two sides of the edge e. Suppose T_{l} and T_{2} are two trees with equal number of vertices, e in T_{1} and f in T_{2}. The edges e and f are said to be equiseparable if either n_{l}(eIT_{I}) = n_{l}(fIT_{2}) or n_{l}(eIT_{I}) = n_{2}(fIT_{2}). If there is an one-to-one correspondence between the ver...
متن کاملA Note on Tensor Product of Graphs
Let $G$ and $H$ be graphs. The tensor product $Gotimes H$ of $G$ and $H$ has vertex set $V(Gotimes H)=V(G)times V(H)$ and edge set $E(Gotimes H)={(a,b)(c,d)| acin E(G):: and:: bdin E(H)}$. In this paper, some results on this product are obtained by which it is possible to compute the Wiener and Hyper Wiener indices of $K_n otimes G$.
متن کاملCoherent Frames
Frames which can be generated by the action of some operators (e.g. translation, dilation, modulation, ...) on a single element $f$ in a Hilbert space, called coherent frames. In this paper, we introduce a class of continuous frames in a Hilbert space $mathcal{H}$ which is indexed by some locally compact group $G$, equipped with its left Haar measure. These frames are obtained as the orbits of ...
