RESUMEN
Objective To study the effect of Pinus yunnanensis on acute alcoholic liver injury in rats and explore its mechanism. Methods A model of acute alcoholic liver injury in mice was prepared by alcohol. The mice were randomly divided into normal control group, model group, positive control group, Pinus yunnanensis low-, medium-and high-dose groups. Mice in the medicine group were given the corresponding medicine by gavage once a day for 7 days. After the last three hours of intragastric administration, the liver and spleen index, ALT, AST and GSH in serum, SOD, MDA and NO in liver homogenates were measured. Histopathological changes of liver were observed by HE staining. Results Compared with model group, Pinecone of Pinus unnanensis high-, medium- and low-dose groups could significantly reduce the liver index in mice (P0.05). HE staining results showed that, the damage of liver tissue in mice of Pinus yunnanensis was significantly improved compared with the model group. Conclusion Pinus yunnanensis has protective effects on acute alcoholic liver injury in mice.
RESUMEN
<p><b>OBJECTIVE</b>To improve the occupational health management levels in electroplating enterprises with quantitative classification measures and to provide a scientific basis for the prevention and control of occupational hazards in electroplating enterprises and the protection of workers' health.</p><p><b>METHODS</b>A quantitative classification table was created for the occupational health management in electroplating enterprises. The evaluation indicators included 6 items and 27 sub-items, with a total score of 100 points. Forty electroplating enterprises were selected and scored according to the quantitative classification table. These electroplating enterprises were classified into grades A, B, and C based on the scores.</p><p><b>RESULTS</b>Among 40 electroplating enterprises, 11 (27.5%) had scores of >85 points (grade A), 23 (57.5%) had scores of 60∼85 points (grade B), and 6 (15.0%) had scores of <60 points (grade C).</p><p><b>CONCLUSION</b>Quantitative classification management for electroplating enterprises is a valuable attempt, which is helpful for the supervision and management by the health department and provides an effective method for the self-management of enterprises.</p>
