Insights about the deleterious impact of a carbamate pesticide on some metabolic immune and antioxidant functions and a focus on the protective ability of a Saharan shrub and its anti-edematous property

In the Algerian desert, individuals often enjoy a soothing cup of herbal tea made from Ephedra alata Decne before bedtime; this aids in their relaxation. Our previous and earlier investigations demonstrated the richness of the shrub in terms of polyphenols and flavonoids and their effective medicinal properties. In the light of that fact, our interest has been aroused to check for other types of metabolites and for the protective ability of the shrub crude extract (SCE) regarding chemically induced edema and subacute toxicity (following a formalin-induced paw edema model and using a carbamate pesticide “pirimicarb” as a toxic agent, in Wistar male rats, respectively). Evidently, the SCE was used as a preventive agent. Swelling of formalin-injected foot was measured, and the anti-edematous ability was expressed as a percent of paw edema. At the end of induced subacute toxicity procedure, many investigations were carried, namely, checking for biochemical several parameters (hepatic, renal), hematological parameters, oxidative stress status (OSS), and histological examining of liver, spleen, and kidney tissues. The results revealed a remarkable anti-edematous effect. Furthermore, the association of the SCE effect has clearly minimized the OSS, the tissue aberrations, and the disturbance of the other metabolic parameters, along with a reduced immunodepression that was provoked under the effect of pirimicarb. In conclusion, pirimicarb has an important deleterious impact on metabolic and immune functions, and the studied shrub has exhibited an amazing protective potential against chemically induced inflammation and toxicity.
