Carbon tetrachloride (CCL4) induced liver fibrosis in experimental models are often used for investigation of hepatoprotective effect of drugs. The potential effect of either silymarin and/or pranlukast against CCL4 induced liver damage was examined in a CCL4 model in rats . Sprague Dawley male rats were intraperitoneally injected with CCL4 and received Silymarin and or pranlukast orally once daily for 6 weeks. Administration with silymarin or pranlukast significantly decreased serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), increased the activities of superoxide dismutase (SOD) catalase and glutathione (GSH) content , decreased malondialdehyde (MDA) content in liver and in addition, they decreased (NO) production

Radiotherapy is an integral part of it; however, it has several complications. Radiation induced burn is a common complication of radiotherapy that requires more effective lines of management rather than the classically used ones. We investigated whether the addition of pentoxifylline (PTX) alone or in combination with topical honey is effective in its management compared to the standard measures. In this prospective study, patients were randomly allocated into three groups each of 50 cases. Group A received standard burn treatment (control group). Group B received additionally 400 mg PTX twice daily. Group C received the same treatment as Group B with adding topical purified honey ointment. Patients were assessed initially and subsequently after 4 and 12 weeks, for projected coetaneous surface area (PCSA) of burn, pain severity, limitation of movement and exudation. There was a striking regression of the mean PCSAs of lesions among groups B and C at 12 weeks, with reduction rates (86±61%) and (76±58%) respectively (p<0.0001***). The addition of honey was associated with marked pain relieving effect and rescue of proper motion. Finally, honey was associated with shorter duration of treatment as 74% of group C patients completely recovered after 12 weeks, compared to only 54% and 36% of groups B and A in order. Combination of PTX and honey is an ideal measure for treatment of radiation-induced burn following breast conservative surgery.

This study aimed to investigate the antimicrobial susceptibility and virulence of extensively drug-resistant (XDR) Aeromonas spp. in wild Mugil cephalus and its surrounding seawater along the coastal road of Port Said, Egypt. Materials and Methods: Specimens were examined bacteriologically, confirmed biochemically, and tested for their sensitivity against 11 antimicrobial agents. Molecular confirmation of the obtained isolates by 16S rRNA was performed, followed by the detection of antimicrobial resistance and virulence genes. Results: Aeromonas spp. was recovered from fish (44%) and water samples (36%). A. hydrophila was the most prevalent identified strain, followed by Aeromonas sobria, Aeromonas caviae, and Aeromonas schubertii. Moreover, 90% of the tested isolates were multidrug-resistant (MDR), while 26.67% were XDR. Tested isolates were r...

Moreover, 90% of the tested isolates were multidrug-resistant (MDR), while 26.67% were XDR. Tested isolates were resistant to β-lactams and sulfonamides (100%), oxytetracycline (90%), and streptomycin (62.22%) but completely susceptible to cefotaxime. XDR isolates successfully amplified resistance genes (blaTEM, sul1, and tetA(A)) but not the (aadA1) gene, although there was phenotypic resistance to streptomycin on plates. All XDR isolates carry the cytotoxic enterotoxin gene (act), but alt gene was detected in only one isolate (12.5%).
Conclusion: Data in this study provide a recent update and highlight the role of wild mullet and seawater as reservoirs for MDR and XDR Aeromonas spp. that may pose a risk to humans as food-borne infection or following direct contact.
