Aim To observe the effects of ketamine on Na+,K+-ATPase,Ca2+-ATPase and NOSase activity in different cerebral cortex in convulsive mice.

Serumal NOS activity, NO content and liver tissue s IκBmRNA expression were assayed 4 hours after "two-hits".

In this paper, NOS activity and level of NOS is measured with exhaustive exercise model.

Objective To investigate the relationship between nitric oxide synthase (NOS) activity and schizophrenia.

After 24 hours once exhaustive exercise the concentrations of nitric oxide in kidney,serum urea nitrogen,serum creatinine,urinary protein and nitric oxide synthase activity are determined.

After the success of the models,divided them into 5 groups according to whether or not pre-given L-NAME(non-selective nitric oxide synthase inhibitor) and the doses: the A group,pre-given saline;the B1 group,pre-given L-NAME5mg;the B2 group, pre-given L-NAME10mg;the B3 group,pre-given L-NAME20mg;the B4 group, pre-given L-NAME30mg.

Histochemical observation of NOS positive cells in gastric mucous of human fetus;

Objective:To explore the rule of the growth and development or configuration or distribution of nNOS positive cells in the mucous layer of the large intestine of human fetus.

Objective:To explore the rule of the development of NOS positive cells in the gastric mucous of human fetus.

Much progress has been made on the research of NOS,the function mechanism of NOS in the plants respond to various environmental stresses has been summarized in this paper.
