RESUMEN
The pregnancy registry for medicine is a common method for risk evaluation for drug safety evaluation during pregnancy. The authors introduced the exploration and practice of the pregnancy drug registry mode based on pharmacy service in Women′s Hospital School of Medicine Zhejiang University. The registry of pregnancy medication with the drug consultation clinic as the fulcrum was managed by the pharmacist team in a homogenization way, and implemented according to the information process of consultation, pharmacy guidance and regular follow-up. In the consultation and follow-up work, the pharmacists established the consultation drug history through three data sources: independent report of the consultant, inquiry of pharmaceutical personnel and case sampling. The pharmacists designed and constructed information screening system, classified the consultation medicine history according to the pregnancy exposure of specific drugs. The prospective research method was designed to meet the characteristics of pregnancy medication. The study was carried out on the relationship between pregnancy exposure and birth defects of offspring. Relying on the improvement of standardization, refinement and information management level of pharmaceutical services, multi center cooperation will be strengthened in the future to carry out continuous research on pregnancy drug exposure registry and follow-up system.
RESUMEN
<p><b>OBJECTIVE</b>To investigate the protective effect of purple sweet potato flavonoids (PSPF) on CCl4-induced acute liver injury in mice.</p><p><b>METHODS</b>Sixty mice were randomly divided into six groups (n=10 in each): blank group, model group, PSPF groups (400 mg*kg(-1), 200 mg*kg-1 and 100 mg*kg(-1)) and positive control group (DDB 150 mg*kg(-1)). Acute liver injury was induced by administration of peanut oil with 0.1% CCl4 (10 mg*kg(-1)) in mice. The viscera index, serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST) and lactate dehydrogenase (LDH) were measured, and the activities of superoxide dismutase (SOD) and the contents of malondialdehyde (MDA) in hepatic tissues were also measured. The pathological changes of liver were observed with microscopy.</p><p><b>RESULTS</b>PSPF significantly decreased serum ALT, AST and LDH levels (P<0.05 or P<0.01) and MDA content in hepatic tissues (P<0.01), increased the activities of SOD (P<0.01).</p><p><b>CONCLUSION</b>Purple sweet potato total flavonoids can prevent CCl4-induced acute liver injury in mice, which may be related to inhibition of lipid peroxidation and reduction of oxygen free radicals.</p>
