It also assesses its influence on the spatial memory abilities of these animals. Adult male Wistar rats were divided into four groups, each containing 10 rats: Control, Camphor, Cd, and Cd + Camphor. Cadmium chloride (5 mg/kg, orally) and camphor (10 mg/kg, intraperitoneally) were administered for 21 consecutive days. The findings revealed that treatment with camphor resulted in elevated levels of GSH, improved activities of SOD and GPx, and reduced MDA levels in the hippocampus of rats exposed to cadmium chloride. Moreover, camphor decreased the expression of pro-inflammatory cytokines, such as TNF-α, IL-1β, and IL-6, while increasing the expression of IL-10. In addition, camphor diminished mRNA and protein amounts of NF-κB in the hippocampus and reduced neuronal death in the CA1 area. It decreased the expression and activity of acetylcholinesterase, enhanced the expression of BDNF and the alpha-7 nicotinic acetylcholine receptor in the hippocampus, and caused a significant improvement in spatial memory.

This study investigated the protective role of purslane (Portulaca oleracea, PUR), a medicinal plant rich in antioxidant bioactives, against Cd-induced oxidative stress and ion transporter dysfunction in Nile tilapia (Oreochromis niloticus). One hundred and eighty fish were divided into four groups (3 replicates per group, 15 fish/replicate): control, PUR (1% dietary inclusion), CdCl₂ (50 µg/L), and CdCl₂ + PUR, and exposed for 60 days. CdCl₂ exposure significantly elevated serum urea, uric acid, creatinine, glucose, and cortisol levels (by 67%, 20%, 78%, 54%, and 202%, respectively; P < 0.001), along with hypocalcemia (↓21%), hypermagnesemia (↑103%), and reduced serum iron (↓73%). Antioxidant enzyme activities in the gills were markedly suppressed (GPx (↓67%), CAT (↓67%), and SOD (↓61%)), with a depletion of GSH (↓58%) and an elevation of MDA (↑55%). The corresponding mRNA expressions of these enzymes in the kidney were downregulated (3.7-6.7-fold; P < 0.001). CdCl₂ also upregulated heat shock proteins hsp60, hsp70, and hsp90 in the kidney (5.7-8.4-fold; P < 0.001), indicating oxidative and cellular stress. Histopathological examination revealed pronounced tissue damage in the kidney and gill structures. Ion regulation was also disrupted by CdCl₂, as evidenced by reduced gill Ca<sup>2</sup>⁺-ATPase (↓81%) and Na⁺/K⁺-ATPase (↓75%) activities, along with significant downregulation of ion transporter genes (pc, nka-α3, atp6v1a, and slc4a4; 2.3-5.2-fold decrease). Furthermore, Cd residues in the gills increased dramatically, reaching approximately 76.6-fold higher levels compared to the control group. However, dietary PUR supplementation significantly alleviated these alterations, restoring enzyme activities, reducing hsp overexpression, repairing altered architecture, reducing Cd accumulation, and normalizing ion transporter function and gene expression (P < 0.001). In conclusion, PUR demonstrates strong protective effects against CdCl₂-induced oxidative damage and ionoregulatory dysfunction in O. niloticus, likely via antioxidant-mediated and cytoprotective mechanisms.
