curcumin and aluminum-phosphide

Aluminum phosphide (AlP) as an effective pesticide may contribute to oxidative stress and adversely influence sperm parameters. This study aimed to investigate the protective role of curcumin and nanocurcumin on oxidative damage in the testis of rats with AlP toxicity.. A total of 42 adult male Wistar rats were equally randomized into the following study groups (n = 7): Control, Control+Curcumin, Control+Nanocurcumin, AlP, AlP+Curcumin, and AlP+Nanocurcumin. The testis tissue was used to investigate the levels of testicular malondialdehyde (MDA), total oxidant status (TOS), total antioxidant capacity (TAC), and reduced glutathione (GSH) as well as the Catalase (CAT) and superoxide dismutase (SOD) enzyme activity. Epididymal sperm was used to perform sperm analysis.. AlP administration led to a significant increase in MDA, and TOS levels and also markedly decreased the SOD activity and the levels of TAC and GSH in testis tissue (p <0.001). Moreover, the motility and viability of sperms were significantly reduced (p <0.001). Curcumin and Nanocurcumin co-administration with AlP remarkably decreased the MDA and TOS level (p <0.001) and significantly increased the GSH and TAC levels as well as the activity of SOD in AlP intoxicated groups (p<0.001). Our findings demonstrated that Nanocurcumin administration has significantly enhanced the sperm quality in AlP intoxicated rats as compared to the control group (p <0.001).. According to the results of this study, Curcumin as a potential antioxidant could be an effective attenuative agent against AlP-induced oxidative damage in testis, especially when it is used in encapsulated form, nanocurcumin.

Aluminum phosphide (AlP) is widely used to protect stored food products and grains from pests and rodents. The availability of AlP, especially in Asian countries it has become a desirable factor to commit suicide. The phosphine produced from ALP is a very reactive radical and a respiratory inhibitor that causes oxidative damage. There is no dedicated antidote or effective drug to manage AlP-induced lung toxicity. The present study aims to evaluate and compare the protective effects of curcumin and nanocurcumin on ALP‑induced subacute lung injury and determine the underlying mechanism.. Rats were exposed to AlP (2 mg/kg/day, orally)+curcumin or nanocurcumin (100 mg/kg/day, orally) for 7 days. Then rats were anesthetized and lung tissues were collected. Oxidative stress biomarkers, genes expression of antioxidant enzymes, participated genes in the SIRT1/FOXO3 pathway, and lung histopathology were assessed by biochemical and ELISA methods, Real-Time PCR analysis, and H&E staining.. Curcumin and nanocurcumin produced a remarkable improvement in AlP-induced lung damage through reduction of MDA, induction of antioxidant capacity (TAC, TTG) and antioxidant enzymes (CAT, GPx), modulation of histopathological changes, and up-regulation of genes expression of SIRT1, FOXO3, FOXO1 in lung tissue.. Nanocurcumin had a significantly more protective effect than curcumin to prevent AlP-induced lung injury via inhibition of oxidative stress. Nanocurcumin could be considered a suitable therapeutic choice for AlP poisoning.

The present study aimed to evaluate the effect of nanocurcumin and curcumin on liver transaminases, lipid profile, oxidant and antioxidant system, and pathophysiological changes in aluminium phosphide (ALP) induced hepatoxicity.. In the aluminium phosphide group, there was a significant increase in MDA, ALT, AST, and AP and total bilirubin, cholesterol, triglyceride, LDL, and VLDL; AST, ALT, total bilirubin, LDL, VLDL, cholesterol, and MDA were significantly decreased; and HDL and TAC were significantly increased compared to ALP (. Nanocurcumin significantly protects the liver against aluminum phosphide toxicity. It is suggested that nanocurcumin-based drugs be developed to reduce the toxic effects of ALP in poisoned patients.
