Abstract

The normal structure as well as ary alterations or effects of both brown
Eobania venniculata and white Theba p < /em>issn» garden snail hepatopancreatic cells
(digestive gland ) due to LCo (1/10 of the LCs)value ) metaldehyde laboratory wheat
bran bait treatments were investigated microscc pically and recoded photographically.
Histological studies showed distinct disturbed, ctivity in the digestive gland tissues of
both white and brown garden snails. The results revealed that: 1-Digestive glands of
both tested snails were composed of multirumber of the digestive tubules with
different type of cells in each tubule. 2- LCe of metaldehyde treatments induced
inflammatory, ballon degeneration, thickining, fibrosis as well as focal manner of
necrosed cells in both white and brown arden tested snails digestive cells.
