    Notes: Abstract A previous study of lactate dehydrogenase (LDH Jin gingival crevicular fluid (GCF) suggested that the concentration is 10 to 25 times that of serum (X=2300 international units/I versus 100 IU/1 for serum). That study used capillary tubes to collect microliter amounts of GCF. Since invasive collection techniques can influence GCF flow, we evaluated LDH activity in GCF collected by filter strips. GCF was collected in a standardized fashion from 10 subjects with mild inflammation (GI=0.5–1.0) and 10 subjects without evidence of gingival inflammation (GI=0). Our results indicate that LDH volume activity was greater for subjects with GI=0 x= 105.529 IV/l) than for subjects with GI=0.5–1.0 (X;=77,66 1 IU/1). but the difference was not significant. LDH total unit activity was significantly greater in subjects with GI=0.5–1.0 versus GI=0 (X=0.048 IU versus X=0.0242 IU. P〈0.0001). The relationship of LDH volume activity to GCF volume, the regression lines fit to the data, and calculation of LDH total unit activity were important for analysis of enzyme activity in GCF.

    Notes: Examination of surface topography in prefusion stages of secondary palatal development in rabbit embryos reveals a sequence of alterations in the surface cells of the epithelium along the medial margins of the palatal processes. A progressive increase in cellular protrusions resembling lamellipodia and filopodia, as well as cellular necrosis, is observed in those areas that undergo fusion. The changes precede fusion and are restricted to fusion sites. Prior to and at the time of epithelial contact between palatal processes, many long slender cellular protrusions are seen bridging the gap between the approximating tissues. The localization of the epithelial alterations and the appearance of similar cellular morphology in other embryonic epithelial fusion events strongly suggest: either an active role of the epithelial cells in the fusion of the secondary palate, or some common fundamental biochemical events that may facilitate or are responsible for the initial adhesion of such tissues.
