RESUMEN

Background: A broad spectrum carbamate fungicide called carbendazim (Carb) is used to combat a number of different fungal diseases. One of the extensively utilized medicinal plants in oriental countries is Coriandrum sativum. Aim: In the current study, the impact of C. sativum seeds extract (CSE) on albino rats' testicular toxicity caused by carbendazim was investigated. Materials and methods: A total of 50 male albino rats were classified into 5 groups [Gp1, Control Gp; Gp2, Coriandrum Gp (CSE); Gp 3, carbendazim Gp (Carb); Gp 4, Co treated CSE with Carb (CSE + Carb); Gp 5, Post treated Carb with CSE (Carb + CSE)]. Results: Carb induced elevation in serum LH. FSH, testicular malondialdehyde (MDA), testicular nitric oxide (NO) markers and testicular injury and it reduced serum testosterone, testicular glutathione (GSH), testicular catalase and PCNA. Treatments of Carb with CSE (CSE + Carb and/or Carb + CSE) improved these parameters and reduced testicular toxicity with best results for Carb + CSE than CSE + Carb. Conclusions: The above findings revealed that; Carb induced testicular toxicity and it supported the hypothesis that the antioxidant characteristics of one or more of CSE constituents can reduce the testicular toxicity of Carb.

RESUMEN

Background: Early identification of antipsychotic poisoned patients who may have a potential risk for intensive care unit (ICU) admission is crucial especially when resources are limited. Nomograms were previously used as a practical tool to predict prognosis and planning the treatment of some diseases including some poisoning conditions. However, they were not previously investigated in antipsychotic poisoning. Aim: The current study aimed to construct a nomogram to predict the need for ICU admission in acute antipsychotic poisoning. Patients and methods: This 2-year study included 140 patients acutely intoxicated with antipsychotics and admitted at Tanta University Poison Control Centre throughout July 2019 to June 2021. Personal and toxicological data, findings of clinical examination and electrocardiography, as well as, results of laboratory investigations at time of admission were recorded. According to the outcome, patients were divided into ICU-admitted and ICU-not admitted groups. Results: The results of this study provided a proposed nomogram that included five significant independent predictors for ICU admission in acute antipsychotic intoxications; the presence of seizures (OR: 31132.26[108.97-Inf]), corrected QT interval (OR: 1.04[1.01-1.09]), mean arterial blood pressure (OR: 0.83[0.70-0.92]), oxygen saturation (OR: 0.62[0.40 to 0.83)], and Glasgow Coma Scale (OR: 0.25 [0.06-0.56]). Conclusion: It could be concluded that the developed nomogram is a promising tool for easy and rapid decision making to predict the need for ICU admission in acute antipsychotic poisoning.

RESUMEN

Copper oxide nanoparticles (CuO NPs) have developed as a significant class of nanomaterial with potential dangers to organisms and the environment in a variety of applications. This study aimed to investigate the impact of costus root extract against CuO NPs induced oxidative stress, alterations in heart structure and functions. 40 adult male rats were assigned randomly to four groups: first; control, second; costus (300 mg/kg body weight/day) orally for 2 weeks, third; CuO NPs (100 mg/kg body weight/day) intraperitoneally for 4 weeks and fourth; CuO NPs + costus. Current results revealed, significant increases in serum levels of creatine kinase-MB, creatine kinase enzyme, lactate dehydrogenase, myoglobin, aspartate aminotransferase, alkaline phosphatase, cardiac TBIRS, total thiol, nitric oxide, and cardiac proliferating cell nuclear antigen after CuO NPs administration when compared with control group. Conversely, statistical significant decreases were detected in cardiac reduced glutathione, catalase, and superoxide dismutase in CuO NPs group as compared with control group. Interestingly, treatment of CuO NPs with costus root extract was associated with significant improvements of the studied parameters, heart structure and functions. CuO NPs-induced toxicity, injury and oxidative stress in rat heart and treatment with Costus root extract could scavenge free radicals producing beneficial effects against CuO NPs.

RESUMEN

Ulcerative colitis (UC) is a chronic inflammatory life-threatening and premalignant disorder with no cure that even might end up with surgical removal of a large section or even all of the colon. It is characterized by relapsing-remitting courses of intestinal inflammation and mucosal damage in which oxidative stress and exaggerated inflammatory response play a significant role. Most of the current medications to maintain remission are symptomatic and have many adverse reactions. Therefore, the potential for improved management of patients with UC continues to increase. Yet, the benefits of using the antiarthritic agent diacetylrhein to counteract inflammation in UC are still obscure. Hence, our study was designed to explore its potential role in UC using a model of dextran sodium sulfate-induced acute colitis in rats. Our results revealed that diacetylrhein targeted the NLRP3 and inhibited the inflammasome assembly. Consequently, caspase-1 activity and the inflammatory cytokines IL-1ß and IL-18 were inhibited leading to a curbed pyroptosis process. Additionally, diacetylrhein revealed a significant antiapoptotic potential as revealed by the levels of pro-apoptotic and anti-apoptotic proteins. Concomitant to these effects, diacetylrhein also interrupted NFκB signals leading to improved microscopic features of inflamed colon and decreased colon weight to length ratio, indices of disease activity, and macroscopic damage. Additionally, a reduction in the myeloperoxidase activity, IL-6, and TGF-ß alongside an increase in the gene expression of Ocln and ZO-1 were detected. To conclude diacetylrhein showed a significant antioxidant and anti-inflammatory potential and therefore might represent a promising agent in the management of acute UC.

RESUMEN

Silver nanoparticles (Ag NPs or nanosilver) have pulled in expanding interest because of their novel physical, substance, and organic properties contrasted with their full scale scaled partners. The goal of this study was to investigate if Avena sativa (AVS) extract could ameliorate Ag NPs toxicity-induced alterations in liver structure and function, DNA damage, apoptosis, and oxidative stress. Twenty adult male rats were assigned randomly to four groups: control, AVS (intragastrically, 5 g/Kg body weight/day) for 2 weeks, Ag NPs (400 mg/kg body weight/day) for 1 week as acute toxicity and Ag NPs + AVS (same therapy of Ag NPs as acute toxicity with AVS). This study demonstrated a statistical significant increase in serum levels of liver function tests (AST, ALT, ALP and globulin), liver DNA damage, apoptotic P53 and Malondialdehyde after Ag NPs administration when compared to control group. Conversely, statistical significant decreases were detected in serum albumin, total proteins, liver reduced glutathione, catalase, superoxide dismutase, glutathione S-transferase and anti-apoptotic Bcl2 in Ag NPs group as compared to control group. Interestingly, treatment of Ag NPs with AVS (Ag Nps + AVS) was associated with significant improvements of the studied parameters, liver structure and functions. Avena sativa (AVS) extract could scavenge free radicals producing beneficial effects against acute Ag NPs hepatotoxicity in rats induced through activation of oxidative stress and apoptosis.
