Background: The study determined the histological layers of the cerebral cortex and hippocampus of the albino rat brain samples has been used in the study. The Cerebral cortex is composed of the Molecular layer, external granular, external pyramidal layer, internal granular layer and interior pyramidal layer. The layers of the hippocampus are alveus, stratum oriens, stratum pyramidale, stratum radiatum, stratum lacunosum and stratum moleculare. The aim of the study is to analyze the detailed histological features of the cerebral cortex and hippocampus layers of albino rats at the magnification of 10X,100X,40X. By using haematoxylin and eosin stain as an observational study. Materials and Methods: The samples were preserved and fixed with the formalin and stained by haematoxylin and eosin and observed with a light microscope. Results: The molecular layer is the superficial layer containing neurons. The outer granular layer of the cells are densely packed. Outer pyramidal layer contains rich pyramidal cells, Inner granular layer contains stellate cells, Inner pyramidal layer contains glial cells and the deeper multiform layer is composed of pyramidal cells. The hippocampus contains three layers of cornu Ammonia CA1, CA2, CA3. CA1 responds to memory and is covered by the choroid plexus. CA2 contains 3 major cell dentate gyrus, pyramidal cells, pyramidal neurons and CA3 composed of stratum lucidum. Conclusion: The study of brain analysis of histological features of the cerebral cortex and hippocampus of the brain adds a greater insight in understanding the histology of various types of layers in rat brain and morphology of brain cells.

Lead is a highly toxic heavy metal. Chronic exposure to lead levels is responsible for significant health effects, particularly in children. Prevention remains the best option for reducing childhood lead exposure, however the knowledge, attitudes and practices to lead exposure is mainly in developing countries. The aim of this study is to create awareness on lead poisoning among college students. A questionnaire survey was conducted among college students through an online survey planet link. A total of 165 students have responded to the survey, a validated questionnaire consists of 20 questions distributed to assess their knowledge and awareness on lead poisoning among the college students. 67% of the participants were aware of lead poisoning and 33% not aware of it.  60% of the participants agreed that water contains lead. The responses have been taken and results were statistically analysed. Seminars and workshops may be conducted to create awareness on the risk factors of lead poisoning in the community.
