The Department of Biology at the College of Science, University of Mosul, discussed a PhD dissertation on Sunday, February 8, 2026, entitled:

“Histological and Physiological Responses to the Effects of Bioactive Compounds of Galangal Plant in Albino Rats Exposed to Oxidative Stress”

submitted by Raya Ghassan Fathi Al-Obaidi from the Department of Biology.

The dissertation investigated the effects of galangal (Alpinia galanga) root oil on the histological and physiological responses of rats exposed to oxidative stress induced by hydrogen peroxide. The study included the assessment of several oxidative stress biomarkers, analysis of gene expression related to heat shock proteins and antioxidant enzymes, as well as evaluation of DNA damage enzyme activity in liver and kidney tissues.

The research also examined pathological histological alterations and investigated the localized expression of inflammatory markers IL-6 and TNF-α using immunohistochemistry techniques.

The examination committee was chaired by:

• Professor Dr. Muneef Abd Mustafa Suleiman – Chairperson
