This is an experimental study to study the pathological changes in the organs of the mannheimiosis rat model treated with sea cucumber extract, Stichopus. This is the first evidence of Vitamin E and Vitamin E2 reversing hypoxia-induced formation of free radicals in a fish brain. In addition, the results show that during hypoxic stress, administration of Vitamin E or related Vitamin E2 leads to reduced oxygen radical formation in the fish brain, reversing neurological malfunction. 1 : extreme in a way that is not normal or that shows an illness or mental problem He is a pathological liar/gambler. The study demonstrates for the first time in an aquatic vertebrate, that hypoxia increases highly chemically reactive radicals of oxygen (e.g., nitric oxide and the super oxide radical) causing oxidative damage to cells and inhibiting protein expression in the hypothalamus, an important integrative center in the fish brain. Harmful responses were diminished after exposure of the fish to the antioxidant vitamin E and estrogens (female reproductive hormones) restoring reproductive endocrine functions. In vertebrates such as Atlantic croaker, low levels of dissolved oxygen (called hypoxia - below 2 mg/L) and insufficient antioxidant levels in the brain result in the initiation of a complex series of pathological changes leading to decreased energy levels and disruption of neuroendocrine (hormone) functions. The new study explains the influence of antioxidants and steroids on reducing pathological impacts of low oxygen on an aquatic vertebrate animal. ![]() ![]() Although pathological examination is not a feasible method of diagnosis, it can elucidate pathological changes, pathogenesis of the disease, and the cause of death in COVID-19 cases.

In the initial phase of the current pandemic, a handful of post-mortem case-series revealed COVID-19-related pathological changes in various organs. Atlantic croaker, Micropogonias undulatus (Sciaenidae).
