Free-living flatworms such as planarians are inexpensive to culture, maintain, and use for toxicologic testing in the laboratory. A considerable number of basic studies by ourselves and othersExpand

Electron microscopic studies of planarian regeneration. I. Fine structure of neoblasts in Dugesia dorotocephala.
Planarian neoblasts were studied during the course of regeneration by electron microscopy. The greatest number of neoblasts were found not in the new blastema of regeneration but in the region of oldExpand

Mitosis in normal and regenerating planarians.
The rate of mitosis in planarians was measured by two methods. First, by tabulating the proportion of nuclei displaying metaphase mitotic figures after varying lengths of time in colchicine. Second,Expand

Acute toxic responses of the freshwater planarian,Dugesia dorotocephala, to methylmercury
Toxic responses of planaria to various aquatic habitat concentrations of methylmercury chloride (MMC) were investigated. One hundred percent lethality occurred within 5 h in 2 ppM MMC, 24 h in 1 ppMExpand

Environmental Familiarity and Feeding in a Planarian
Planarians, in common with higher animals, tend to delay feeding in environmental conditions to which they are not habituated.

Electron microscopic studies of planarian regeneration. IV. Cell division of neoblasts in Dugesia dorotocephala
There has been disagreement regarding the source of new cells for planarian regeneration. Electron microscopy was used to study this problem in surgically decapitated asexual Dugesia dorotocephala.Expand

Effects of photoperiods and melatonin on planarian asexual reproduction
Asexual planarians of the species Dugesia dorotocephala exhibit a distinct day-night rhythm of fissioning under the influence of normal photoperiod; fissioning occurs only at night. This rhythm isExpand

Neoplastic transformation in the planarian: I. Cocarcinogenesis and histopathology.
Although several investigators have reported that exposure to mammalian carcinogens induces abnormal tumorlike growths and teratogenic remodeling in planarians, there is no general agreement thatExpand
