Abstract

Background & Objective: Tetra Carbon Cholride has been known as reference hepatotoxin because it can cause necrosis, fatty change, cirrhosis and cancer liver. Silymarin has hepatoprotective and anti hepatoxin effect. This study was done to determine the protective effect of Silymarin in acute hepatotoxicity of CCl4 in rats.

Materials & Methods: In this experimental study, we chose 25ml/kg dose of CCl4 (in mineral oil solvent) as an optimum dose. The hepatotoxic effects of intraperiotoneal injection of CCl4 for obtaining parameters of toxicity and therapeutic effects have been examined. According to enzymatic results (increase in ALT and AST) and histopathologic changes (grading the changes in liver including cytoplasmic granularity, cloudy swelling, necrosis and fatty change), the interval between prescribing silymarin and sampling  was determined. Silymarin as a suspension in propylene glycol CMC 2% (3/2 ratio) has been prescribed in 50, 200 and 800mg/kg doses and serum and liver samples were obtained. Negative control group received silymarin vehicle in CCl4 solvent, drug control received 800 mg/kg of silymarin in CCl4 solvent and positive control received silymarin vehicle after injecting CCl4.

Results: The results showed that prescribing 50mg/kg silymarin one hour after injecting CCl4, in addition to inhibiting transaminase activity, prevents progress of liver injury up to 50% of positive control group. Cellular repair and regeneration are also enhanced, So the grade 3necrosis in positive control group is decreased to grade 0.5 in silymarin gourp in 48 hours prescribing silymarin (50mg/kg).

Conclusion: This study showed that up to six hours after injecting CCl4 significantly prevents hepatotoxicity, and cause acceleration in repair of liver injuries.

Abstract

In December 2019, the new acute respiratory disease spread in China presented with fever and dry cough known to be resulted from the new Corona Virus as the COVID-19. In Iran, the first case was reported on 20th of February 2020. Our management team in Golestan University of Medical Sciences held an immediate meeting to decide how to manage the cases suspected to the COVID-19.The two main hospitals had been selected as the Corona center in the Golestan province, northern Iran. Admitting patients other than COVID-19 has been stopped in these hospitals, and all patients had been transferred to the other hospital in Gorgan city and those in the recovery state had been transferred to a hotel prepared for this purpose. The capacity of Sayyad-e-Shirazi hospital was 300 bed for admission and 25 ICU beds that had been increased to 44 ICU beds (30 percent increases) to be prepared for COVID-19 admission. Clinical groups and specialists had been organized with special duty for each part. After 3 months of COVID-19 crisis, Sayyad-e-Shirazi hospital with 300 beds is in a good shape and admission of severe cases has been decreased.
