Effects of posterior amputation on the cerebral neurosecretory cells of Indian earthworm, Lampito mauritii (Kinberg)

Background: Earthworms are subjected to predator attacks and agricultural practices and thus nature has gifted them the power of restoration of loss of segments. In absence of discrete endocrine gland cerebral neurosecretory system may play important role in wound healing and regeneration of lost segments. Aim: Present aim of our paper is to study initial cytomorphological changes in the cerebral neurosecretory cells following posterior amputation in topsoil Indian earthworm species Lampito mauritii. Method: Following posterior amputation dissected cerebral ganglia were fixed in Bouin’s fluid and processed for conventional neurosecretory staining techniques: Paraldehyde Fuchsin and Chrome Alum Haematoxylin Phloxin. Result: In contrast to control, cerebral neurosecretory cells following amputation displayed distinct cellular change such as release followed by synthesis of neurosecretion for healing up of wounds and subsequent regeneration. Conclusion: Our preliminary study indicates cerebral neurosecretory cells are involved in healing up of wounds and subsequent regeneration in earthworm, Lampito mauritii. *Correspondence to: PS Chaudhuri, Professor of Zoology, Earthworm Research Laboratory, Tripura University, Suryamaninagar-799022, Tripura, India, Tel: 9863312480; E-mail: priya_1956@rediffmail.com
