The Regional Advisory Committee on Cancer (RACC) was established in 1997 to carry forward the recommendations of the 1996 Campbell Report and to provide advice to the Department of Health, Social Services and Public Safety on the future development of cancer services. (Appendix 1) The 27 members of RACC come from the Health and Social Services Councils (which represent the interests of the public), Trusts, Boards, primary care and the Department. Members are listed in Appendix 2 RACC held its first meeting in June 1997 and has continued to meet twice a year since then. The Northern Ireland Cancer Forum was established in 1999 and is a subgroup of RACC. It was recommended that a Forum should be developed to provide meeting point for all voluntary and statutory bodies dealing with cancer in Northern Ireland. The Forum has now met on seven occasions and continues to work well with a unity of purpose. åÊ åÊ

Section 75 of the Northern Ireland Act 1998 requires each public authority, in carrying out its functions, to have due regard to the need to promote equality of opportunity, and also to the desirability of promoting good relations. While the Department, and its associated bodies (includes Health and Social Services Boards, Trusts and Agencies) have made good progress in meeting the statutory obligations set out under Section 75, the work to date has mainly focused on processes, awareness raising, learning new ways to consult, and carrying out Equality Impact Assessments. åÊ

The monocarboxylate transporter MCT2 belongs to a large family of membrane proteins involved in the transport of lactate, pyruvate and ketone bodies. Although its expression in rodent brain has been well documented, the presence of MCT2 in the human brain has been questioned on the basis of low mRNA abundance. In this study, the distribution of the monocarboxylate transporter MCT2 has been investigated in the cortex of normal adult human brain using an immunohistochemical approach. Widespread neuropil staining in all cortical layers was observed by light microscopy. Such a distribution was very similar in three different cortical areas investigated. At the cellular level, the expression of MCT2 could be observed in a large number of neurons, in fibers both in grey and white matter, as well as in some astrocytes, mostly localized in layer I and in the white matter. Double staining experiments combined with confocal microscopy confirmed the neuronal expression but also suggested a preferential postsynaptic localization of synaptic MCT2 expression. A few astrocytes in the grey matter appeared to exhibit MCT2 labelling but at low levels. Electron microscopy revealed strong MCT2 expression at asymmetric synapses in the postsynaptic density and also within the spine head but not in the presynaptic terminal. These data not only demonstrate neuronal MCT2 expression in human, but since a portion of it exhibits a distinct synaptic localization, it further supports a putative role for MCT2 in adjustment of energy supply to levels of activity.

The ultrastructure of the male reproductive system of Didymocystis wedli was studied for the first time, demonstrating spermiogenesis and spermatogenesis at different cell stages. The spermatozoa morphology was compared with that of other Digenea species. It was observed that the different cells of the spermatogenesis process follow the classic pattern reported for the majority of the parasitic platyhelminthes. During spermiogenesis, rootlet fibers, electrondense bodies and median cytoplasmic process were not observed. The mature spermatozoa of D. wedli were filiform, presenting nucleus, mitochondrion and two 9+1 axonemes, with a biflagellate distal extremity.

Autotransplantation of spleen tissue has been done, in the past ten years, in children with schistosomiasis mansoni with bleeding varices. The purposes of this investigation were: (1) to study the morphology and function of the remnant spleen tissue; (2) to quantify the production of tuftsin; and (3) to assess the immune response to pneomococcal vaccine of these patients. Twenty three children, who underwent splenectomy and autologous implantation of spleen tissue into the greater omentum were included in this investigation. The average postoperative follow-up is five years. Splenosis was proved by colloid liver-spleen scans. Search for Howell-Jolly bodies assessed the filtration function. Tuftsin and the titer of pneumococcal antibodies were quantified by ELISA. Splenosis was evident in all children; however, it was insufficient in two. Howell-Jolly bodies were found only in these two patients. The mean tuftsin serum concentration (335.0 ± 29.8 ng/ml) was inside the normal range. The immune response to pneumococcal vaccination was adequate in 15 patients; intermediate in four; and inadequate in four. From the results the following conclusions can be drawn: splenosis was efficient in maintaining the filtration splenic function in more than 90% and produced tuftsin inside the range of normality. It also provided the immunologic splenic response to pneumococcal vaccination in 65% of the patients of this series.

The overall objective of the Health, Social Services and Public Safety (HSSPS) family is to promote and improve the health, social wellbeing and safety of the whole population. The bodies which make up the HSSPS family are the Department of Health, Social Services and Public Safety (DHSSPS), four Health and Social Services Boards, nineteen HSS Trusts, five specialist agencies, the Mental Health Commission, four HSS Councils, the Northern Ireland Council for Postgraduate Medical and Dental Education, the National Board for Nursing, Midwifery and Health Visiting and the Fire Authority for Northern Ireland. The Mental Health Commission and the National Board for Nursing, Midwifery and Health Visiting are at different stages in their equality work and are not therefore included in this document. They will be consulting separately. åÊ
