Mainly using protein - film voltammetric technique, we have achieved direct electrochemical response of lots of proteins such as hemoglobin, myoglobin, cytocrome c, cytocrome b5, horseradish peroxiase, GOD ,Vitreoscillia sp. haemoglobin, etc., at a series of protein membrane modified electrodes, for instance, protein/kieselgubr, protein/polyethylene glycol, protein/polyethyleneimine, protein/phosphatidylcholine, protein/DNA, protein/montmorillonite/polyvinyl alcohol, protein/silver nanoparticle/ cysteamine membrane modified electrode, etc., which are prepared by casting, incorperating or layer by layer self-assembly methods. Electrochemical behavior of these proteins in the films have been studied, and their structural and conformational changes have also been examined with spectrometric techniques.

Myriocin is a potent inhibitor of sphingosine biosynthesis by blocking the first enzyme in the pathway, serine palmitoyltransferase.

嗜热菌杀酵母素是一种有效的鞘氨醇生物合成抑制剂，能阻止合成途径中第一个酶——丝氨酸软脂酰转移酶。

After treatment with the above hormones, the rats were established anesthesia with urethan (1g/kg, i. p.); polyethylene catheters were inserted into the external jugular vein and the common carotid artery for drug administration, and then blood pressure was recorded. The arterial catheter was connected to a pressure transducer, and the blood pressure was displayed on the channel of BL-310 Experimental System of Biological Function through IBM computer. We assessed the changes of resting arterial blood pressure, the pressor responses of angiotensin Ⅱ(Ang Ⅱ, 0.01mg/kg), noradrenaline (NA, 0.01mg/kg) and adrenaline (Adr, 0.016mg/kg). The depressor responses of Ach (0.006mg/kg) and carotid sinus baroreflex were also discussed after treatment with the hormones in OVX rats.
