“…Apoptosis is an orderly death process regulated by genes that play a vital role in maintaining the internal environment of the body. Oxidative stress also changes the intracellular concentration of Ca 2+ in spermatozoa and causes sperm apoptosis, as marked elevation of Ca 2+ stimulates hydrolytic enzymes, causing an exaggeration in energy expenditure, an impairment in energy production, and resulting in cell death [ 45 ].…”

Oxymetholone is one of the anabolic steroids that has widely been used among teenagers and athletes to increase their muscle bulk. It has undesirable effects on male health and fertility. In this study, the therapeutic effects of platelet-rich plasma (PRP) on oxymetholone-induced testicular toxicity were investigated in adult albino rats. During the experiments, 49 adult male albino rats were divided into 4 main groups: Group 0 (donor group) included 10 rats for the donation of PRP, Group I (control group) included 15 rats, Group II included 8 rats that received 10 mg/kg of oxymetholone orally, once daily, for 30 days, and Group III included 16 rats and was subdivided into 2 subgroups (IIIa and IIIb) that received oxymetholone the same as group II and then received PRP once and twice, respectively. Testicular tissues of all examined rats were obtained for processing and histological examination and sperm smears were stained and examined for sperm morphology. Oxymetholone-treated rats revealed wide spaces in between the tubules, vacuolated cytoplasm, and dark pyknotic nuclei of most cells, as well as deposition of homogenous acidophilic material between the tubules. Electron microscopic examination showed vacuolated cytoplasm of most cells, swollen mitochondria, and perinuclear dilatation. Concerning subgroup IIIa (PRP once), there was a partial improvement in the form of decreased vacuolations and regeneration of spermatogenic cells, as well as a reasonable improvement in sperm morphology. Regarding subgroup IIIb (PRP twice), histological sections revealed restoration of the normal testicular structure to a great extent, regeneration of the spermatogenic cells, and most sperms had normal morphology. Thus, it is recommended to use PRP to minimize structural changes in the testis of adult albino rats caused by oxymetholone.

“…NH 3 is lipid-soluble and can cross cell membranes, causing damage to the non-specific immune system of crustaceans and leading to greater susceptibility of crustaceans to disease [ 6 ]. Studies have shown that most aquatic organisms are susceptible to ammonia toxicity, and there have been many studies on the effects of ammonia on the disease resistance of marine organisms (e.g., fish and shrimp) [ 7 , 8 ]. Several mechanisms of ammonia toxicity have been summarized, including gill and liver damage, acid-base disturbances in the body, and disturbances in the electrochemical gradient [ 9 ].…”
