[Effects of Cinnabar and Realgar in Angong Niuhuang powder on heat shock protein, nitric oxide synthase and inflammatory cytokines in contusion cerebral edema].

Objective: To explore the pharmacological mechanism of Cinnabar and Realgar in Angong Niuhuang powder (ANP).

Methods: SD rats were randomly divided into six groups (12 rats/group): normal controls group (NS group), contusion cerebral edema model group( CCE group) , cerebral edema rats administrated by cinnabar 0. 15 g/kg 1h (CA group), cerebral edema rats administrated by realgar 0.

[Effects of cinnabar and realgar in angong niuhuang powder on lactate dehydrogenase and its isoenzymes in rats with infectious cerebral edema].

Objective: To explore the pharmacologic mechanism of cinnabar (CA) and realgar (RG) in Angong Niuhuang powder (ANP) by way of studying the characteristics of their effects on organism under physiologic and pathologic states.

Methods: SD rats were randomly divided into six groups, 8-10 rats in each group. Group A: untreated normal rats; Group B: normal rats administered by ANP (drug I) 278 mg/kg; Group C: normal rats administered by ANP subtracted CA and RG (drug II) 222.
