RESUMEN
Acute suppurative thyroiditis(AST) is a rare thyroid disease, mostly caused by infections such as Staphylococcus aureus, and it is difficult to distinguish from subacute thyroiditis(SAT) at the beginning of the disease. Here we report the clinical data of a young male patient who was initially misdiagnosed as SAT, but was clinically diagnosed as AST with DNSIs accompanied by LS. The clinical features and treatment, combined with related literature, aim to enhance clinicians' understanding of this disease.
RESUMEN
Aim To investigate the protective effect of catechin on cerebral ischemia-reperfusion injury in rats and its mechanism.Methods 40 rats were randomly divided into 5 groups:sham operation group,model group and 50,100 and 200 mg·kg~(-1) catechin groups,with 8 rats in each group.The model of focal cerebral ischemia-reperfusion in rats was established with modified sutured-occluded method.The rats in catechin groups were injected with catechin at the matched concentration.The rats in sham operation group and model group were injected with saline.And all rats were given more time in 2 hours after ischemia.Rats were sacrificed for histologic examination after the behavioral test,and their brains were taken to assay the activities of MPO and NOS.Results Catechin at different dosages(50,100 and 200 mg·kg~(-1))could obviously decrease neurological deficit score,repair histological injury,and reduce the activities of MPO and NOS in rats of focal cerebral ischemia-reperfusion injury.Conclusions Catechin can relieve the cerebral ischemia reperfusion injury,and its mechanism may be partly related to the effects of its antiinflammation and antioxidation.
