Cells with many of the features of mast cells develop in cultures of normal mouse hematopoietic cells containing mast cell growth factor (1-8), an activity similar or identical to interleukin 3 (IL-3) ~ (9-11), histamine-producing cell-stimulating factor (9), or P cell-stimulating factor (12-14). Large numbers of these cells (>10 s) can be generated as(More)
We introduce the notions of Heegaard splittings and thin multiple Heegaard splittings of 1-submanifolds in compact orientable 3-manifolds, which are generalizations of those of bridge decompositions and thin positions. We show that either a thin multiple Heegaard splitting of 1-submanifold T is also a Heegaard splitting with minimal complexity or the(More)

Let D(p, q) be the usual knot diagram of the (p, q)-torus knot; that is, D(p, q) is the closure of the p-braid (σ −1 1 σ −1 2 · · · σ −1 p−1) q. As is well-known, D(p, q) and D(q, p) represent the same knot. It is shown that D(n + 1, n) can be deformed to D(n, n + 1) by a sequence of {(n − 1)n(2n − 1)/6} + 1 Reidemeister moves, which consists of a single RI(More)
We determine all the Q-fundamental surfaces in (p, 1)-lens spaces and (p, 2)-lens spaces with respect to natural triangulations with p tetrahedra. For general (p, q)-lens spaces, we give an upper bound for elements of vectors which represent Q-fundamental surfaces with no quadrilateral normal disks disjoint from the core circles of lens spaces. We also give(More)
Let M be a 3-manifold with a regular cell decomposition {B 3 k }. In [B], the first author shows: If M contains an essential lamination L 0 , then there is an essential lamination L in M , which is in normal form with respect to the cell decomposition {B 3 k }. In the same paper, by using the result above, he proposes a procedure for determining whether a(More)
Peritoneal mast cells and macrophages are commonly used to study functions of these two types of cells (1-3). Although many investigators have studied the production of peritoneal macrophages both in vivo (4-6) and in vitro (7, 8), only a few investigators have taken an interest in production of peritoneal mast cells (9-11). Both mast cells and macrophages(More)
