In
Nigeria, chloroform inhalation is a frequent method of rodent killing for
study. The purpose of this study is to see how this form of sacrifice affects
the cerebellum and hippocampus of Wistar rats. Twenty male Wistar rats,
weighing 160 to 180 grammes, were separated into four groups, each with five
rats. The control group, Group A, was sacrificed by cervical dislocation (a
widely acceptable non-inhalation method of sacrifice). Groups B, C, and D were
given 5 minutes of chloroform once a day (group B), twice a day for two days,
and three times a day for three days. Four brains from each group were
processed for antioxidant assays, and one brain from each group was preserved
in Bouin's fluid for histological examinations. Our findings reveal that
inhaling chloroform had a dose-dependent negative impact on the antioxidant
parameters investigated. That is, as the number of days increased, the negative
effect became more pronounced. The histology findings confirmed this, with
indications of cell necrosis in the cerebellum and hippocampus regions. This,
too, demonstrated dosage dependence. As a result of our findings, we believe
that chloroform inhalation is not the method of choice for rat death while
investigating brain tissues or conducting brain-related research. As a result,
chloroform sedation is not an appropriate method of rat sacrifice for
experimental reasons, especially for investigating the rat brain.
