[Changes of large conductance Ca(2+)-activated K(+) channels on coronary smooth muscle cells from diabetic rats].

Objective: To investigate the changes of large conductance Ca(2+)-activated K(+) channel (BK channel) on coronary smooth muscle cells from diabetic rats.

Methods: Streptozotocin-induced rat diabetic animal model was used. Coronary smooth muscle cells were isolated by enzyme digestion.

[The pathological observation of acute intoxication by Alangium Chinese in mice].

Objective: To investigate the pathological change of mice organ intoxicated by Alangium Chinese and its poisoning mechanism.

Methods: Mice were intoxicated by gavage with extract of Alangium Chinese. Then the histopathologic examination was made for evaluating the pathological changes in the organs of the poisoned mice by HE staining.
