The most commonly prescribed medication for autoimmune disorders is Azathioprine (AZA), which negatively affects renal function and tissue structure. The aim of this work was to measure the therapeutic impact of Zingiber officinale L. extract (ZOE) on improving the function and structure of AZA-induced renal damaged tissue. Methods: 70 rats with a weight range of 200±10 g and an age of 95±5 days were chosen for this experimental study. The animals were grouped into seven groups of ten, with two groups receiving no treatment (control groups) and five groups receiving ZOE, AZA, “AZA + ZOE”, and normal saline. AZA was given intraperitoneally, and ZOE was given by gavage (i.e., nasogastric tube) for 21 days. Finally, urea, uric acid, creatinine parameters, and the diameter of some key or important parts of the kidney were measured in different animal groups. Results: it was found that the use of AZA (50 mg/kg) increased serum urea and creatinine concentrations, blood uric acid in comparison to the group of control (P<0.05). Whereas injecting ZOE (200 mg/kg) induces a considerable decrease in the concentration of the compounds mentioned above as compared to control animals and animals given AZA (P<0.05). Furthermore, the findings revealed that AZA caused inflammation and kidney tissue destruction, while ZOE improved, restored, and recovered the affected kidney tissue. Conclusion: according to the research findings, it can be decided that ZOE has a protective and therapeutic impact on kidney tissue owing to its strong antioxidant attributes and its ability to inhibit free radicals produced by azathioprine
Depression is one of the most common mental disorders and numerous medications are used to reduce the psychotic symptoms. The aim of this study was to evaluate the therapeutic effects of two commonly used antidepressant drugs, including Fluoxetine (Flx) and Imipramine (IMP) to improve depressive-like behaviors as well as the activity of hypothalamic pituitary-adrenal cortex (HPA). Methods: Initially, 40 adult male albino rats weighing 25±5g were selected for this experimental study. The animals were kept or housed in separate cages under standard temperature (25±1°C) and light-dark conditions (12 hours light/dark cycle). Rats were divided into four groups: each group containing 10 rats, control, immobility stress, Flx receiver, and IMP receiver. Polyethylene restrainer was used to induce immobility stress for 14 days. Finally, the parameters of IMT, ST, serum levels of corticosterone and glucose were evaluated in all four mentioned groups. Results: The results showed that the patient group's immobility time (IMT) increased compared to the control group, but the patient group's swimming time (ST) decreased compared to the control group. The effect of immobility stress on IMT, ST, corticosterone, and glucose factors in the patient group was increasing and decreasing, respectively, whereas the effect of Flx drug on these mentioned factors was decreasing, increasing and respectively, while the effect of IMP on all mentioned factors was decreasing and increasing, respectively. Conclusion: Based on the results, it can be concluded that the antidepressant Flx and IMP drugs have various effects on the HPA activity, and the application of immobility stress causes depressive-behavior. Moreover, Flx is more effective than IMP in the treatment of depressive behaviors
Psoriasis is a chronic, inflammatory condition that primarily affects the skin, hair, and joints and is associated with significant humanistic and economic consequences. Psoriasis was induced in mice in this work using an imiquimod 5% cream, an immune response modifier that can cause psoriasis-like skin inflammation when given orally. Paquinimod is prepared as a suspension and has been orally given to mice before imiquimod application. The current study found that paquinimod suspension reduced psoriasis area and severity index, spleen index, skin thickness ,TNF-α,IL-23,IL17 level and gene expression of TNF-α,Nf-KB,IL-1B,IL-17in the (Paquinimod suspension+imiquimod) group substantially more than the (vehicle suspension+imiquimod) groups.
Introduction: The newly-launched strain of the Staphylococcus aureus, methicillin-resistant S. aureus, is considered the most emerging bacterium in-hospital infections globally. Objectives: The current research focused on the prevalence and virulence features of methicillin-resistant S. aureus (MRSA) bacteria recovered from urinary tract infections (UTIs) cases. Patients and Methods: A total of 710 urine specimens were taken from hospitalized patients who suffered from UTIs. S. aureus was recovered from urine specimens using the microbial culture. S. aureus antimicrobial susceptibility was assessed toward oxacillin and cefoxitin antimicrobial disk to determine the MRSA strains. The polymerase chain reaction (PCR) assessed the distribution of antimicrobial resistance encoding genes. S. aureus antimicrobial resistance was evaluated by disk diffusion. Results: Fifty-five out of 710 (7.7%) urine specimens were positive for the MRSA bacteria. The uppermost antibiotic resistance was obtained against penicillin (100%), ceftaroline (100%), gentamicin (87.2%), erythromycin (76.3%), and ciprofloxacin (69.0%). BlaZ (100%) and tetK (85.4%) had the higher frequency amid examined antimicrobial resistance-encoding genes. Conclusion: The high prevalence of MRSA isolates harboring antimicrobial resistance-encoding genes in the UTIs suggests that diseases caused by them need more expansion healthcare monitoring with essential demand for novel antimicrobials.
Psoriasis is a common chronic skin condition characterized by infiltration of inflammatory cells into the epidermis and altered keratinocyte differentiation. In this work, psoriasis was induced by an imiquimod 5% cream, an immune response modifier that can induce psoriasis-like skin inflammation when applied topically in mice. Guggulsterone prepared as a suspension and has been orally given to mice before imiquimod application. The results of the current study showed that guggulsterone suspension can significantly reduce psoriasis area and severity index in (guggul suspension + imiquimod group as compared with both control group and (vehicle suspension + imiquimod ) group.
