Evaluation of novel programs in health counseling – their effectiveness in the oral health of young children, and their acceptance by parents and professionals in public dental service.

Aim and design: To evaluate family-based health counseling for young children, and to study the significance of adding parental self-care or the training of professionals to the programs. The effectiveness and acceptability of the programs were evaluated by comparing two new programs with an earlier one. Subjects and methods: The study was carried out in Vantaa, which was divided into three study areas. The subjects consisted of children born in 2008, particularly fi rstborn children, while children born in 2006 formed the historical control. The fi rst of the new programs emphasized oral hygiene and use of fl uoride, and the second program focused on proper diet and use of xylitol. The main outcome measure was mutansstreptococci (MS) in the dental biofi lm of two-year-olds, and the opinions of parents and dental professionals were evaluated using questionnaires. Results: The programs found wide acceptance among dental professionals. There were no group-related differences found in the MS scores of the two-year-olds. However, all groups combined, father’s advanced level of education and child’s proper use of xylitol were associated with negative MS scores. In the opinion of parents, the oral healthcare guidance at least somewhat met their expectations. Conclusions: The present fi ndings suggest that providing training and support for professionals in health education is important. The addition of parental self-care to supplement programs aimed at young children does not improve the program, although it may improve parental readiness to change their own health habits. Counseling for families might be best carried out through a routine patient-centered program.

Regulation of Spermatogenesis: Differentiation of GFP-labeled Stem Cells and the Function of Cytoplasmic Bridges

During spermatogenesis, different genes are expressed in a strictly coordinated fashion providing an excellent model to study cell differentiation. Recent identification of testis specific genes and the development of green fluorescence protein (GFP) transgene technology and an in vivo system for studying the differentiation of transplanted male germ cells in infertile testis has opened new possibilities for studying the male germ cell differentiation at molecular level. We have employed these techniques in combination with transillumination based stage recognition (Parvinen and Vanha-Perttula, 1972) and squash preparation techniques (Parvinen and Hecht, 1981) to study the regulation of male germ cell differentiation. By using transgenic mice expressing enhanced-(E)GFP as a marker we have studied the expression and hormonal regulation of beta-actin and acrosin proteins in the developmentally different living male germ cells. Beta-actin was demonstrated in all male germ cells, whereas acrosin was expressed only in late meiotic and in postmeiotic cells. Follicle stimulating hormone stimulated b-actin-EGFP expression at stages I-VI and enhanced the formation of microtubules in spermatids and this way reduced the size of the acrosomic system. When EGFP expressing spermatogonial stem cells were transplanted into infertile mouse testis differentiation and the synchronized development of male germ cells could be observed during six months observation time. Each colony developed independently and maintained typical stage-dependent cell associations. Furthermore, if more than two colonies were fused, each of them was adjusted to one stage and synchronized. By studying living spermatids we were able to demonstrate novel functions for Golgi complex and chromatoid body in material sharing between neighbor spermatids. Immunosytochemical analyses revealed a transport of haploid cell specific proteins in spermatids (TRA54 and Shippo1) and through the intercellular bridges (TRA54). Cytoskeleton inhibitor (nocodazole) demonstrated the importance of microtubules in material sharing between spermatids and in preserving the integrity of the chromatoid body. Golgi complex inhibitor, brefeldin A, revealed the great importance of Golgi complex i) in acrosomic system formation ii) TRA54 translation and in iii) granule trafficking between spermatids.
