Background: This study aimed to investigate the potential bioactivity and the ameliorative role of Galaxaura
oblongata (G. oblongata) against LPS-induced toxicity by using hematological parameters.
Objective: It is aimed also to examine its protective effect using the immunohistochemistry of liver and lungs as biomarkers
in male BALB/C albino mice.
Materials and Methods: The current study carried out using different in-vitro and in-vivo assays such as phytochemical,
antioxidants, anti-inflammatory for in-vitro where the hematological and immunohistochemistry for lung and liver were
investigated in vivo.
Results: There are no previous studies were performed to investigate the in vivo and in vitro effects of the G. oblongata
extracts as antioxidant and anti-inflammatory due to their rareness compared to other red algae. LPS treated mice revealed a
significant decrease in total number of WBCs, RBCs, platelets, and HGB%, MPV, MCV and MCHC compared to the control
group. On contrast, the HCT and MCHC were increased in the induction group which was treated with LPS compared to the
control group. Furthermore, the immunohistochemistry results of the present study revealed the protective effect of G.
oblongata compared to the induction group. G. oblongata can be used as protective marine natural products against the toxicity
induced by LPS.
Conclusion: It exhibited a significant ameliorative role against the alterations in the hematological parameters and
immunohistochemistry of liver and lungs, and helps to reduce as well as coordinate the acute inflammations caused by TNF.
