The B15/Bw21/Bw35 related specificities 'Bu' and 'SV' have been studied in Bristol and in Leiden, both independently and with mutually exchanged sera and cells. Evidence is presented that these specificities are likely to be discrete though very closely related antigens occurring with a combined phenotype frequency of about 1% in Dutch and English Caucasians. SV may be associated with Aw36, while no clear-cut haplotype or phenotypic association has yet emerged for Bu with any HLA-A or C locus antigen. Bu and SV appear t o be related to the variant of B15 reported to be common in Negroid populations.

Reactivity of two Cw5 and three Cw7 antisera was compared in the standard NIH and the Two Colour Fluorescence (TCF) techniques. Contrary to the NIH, the TCF method yielded strong positive reactions which enabled clear assignment of the Cw5 and Cw7 specificities. The TCF technique combines three factors that increase the sensitivity of serum reactions: 1. typing on B lymphocytes, 2. prolonged incubation and 3. staining of the lysed cells with ethidium bromide.

Supported in part by the National Institutes of Health (Contract PH‐43‐65‐992), the Dutch Organization for Applied Research (TNO), the J. A. Cohen Institute for Radiology and Radiation Protection, the Whitehall Foundation, and the Dutch Organization for Pure Research (FUNGO). The results of testing erythrocytes from eight mouse strains with 20 haemagglutinating antisera and five lymphocytotoxic antisera, using a Technicon Haemagglutinating Autoanalyser, are presented. The suitability of the autoanalyser to regular H–2 typing is proved and the adaptability of this methodology to an investigation of the haemagglutinating capacity of lymphocytotoxic antisera is demonstrated. The implications of specific haemagglutination in the autoanalyser by antisera defining the H–2 ‘cytotoxic’ antigens are discussed.

Tra&ccedil;ando uma linha reta que partia de seu apartamento e culminava na S&eacute;, local em que estava Dalai Lama, Henk iniciou sua caminhada pelas ruas da cidade capturando imagens cotidianas contrastadas com um fundo escuro que progressivamente tornava-se claro. O ensaio pode ser tomado como uma met&aacute;fora da fus&atilde;o entre o sagrado e o profano, da miscigena&ccedil;&atilde;o entre divino e mundano e tamb&eacute;m da espiritualidade como um caminho ao longo do qual objetos s&atilde;o religados</p>
