Five, pharmacological evaluation
Experiment 1
1. to the provide protection of anesthetized rat myocardial ischemia-reperfusion injury
Experimental technique:
Get the healthy SD rat, body weight 240-260g, random packet: blank group, FUFANG DANSHEN PIAN group, the application's solid preparation of salvianolic acid A of red sage root group.Place equivalent environment to raise 2 days free diet in advance.After raising end in advance, make an experiment, animal is weighed, and 20% urethane is pressed the 0.6ml/100g abdominal injection; After treating that anesthesia is satisfied, lie on the back and be fixed on the mouse plate, trachea cannula connects respirator; By 10~12ml Tidal volume, 70 times/minute frequency is exhaled, and continuous positive pressure breathing is inhaled: exhale than being 1: 1.According to respiratory rate and degree of depth adjustment respiration parameter.Connect electrocardiograph subsequently, survey normal ECG.Cut off front field of operation hair, iodine disinfection is cut off skin, subcutis, front muscle and manadesma 3~4cm; It is long to separate intercostal muscle 3cm with the 18# vascular clamp along the 3rd intercostal passivity, opens thoracic cavity and pericardium, recording ecg; Strut 3,4 ribs, refer to hold thoracic cavity, rat right side with left hand four, the assistant upwards pushes away thymus gland with the ophthalmology tweezer; Between left auricle of heart and pulmonary conus, find ligation sign blood vessel great cardiac vein, the 2mm place is not with there being wound roundlet pin band 6-0 silk thread threading below left auricle of heart, and depth of needle is 1~1.5mm; Wide 2~3mm, recording ecg behind the threading gives corresponding soup through the tail vein; Recording ecg behind the administration 10min, and with one the band groove little plastics pipe pad at the ligation position, the ligation above that of two rear line heads.At once recording ecg after the ligation is cyanosis or the II S-T section back of a bow that leads with left chamber antetheca and upwards raises greater than 0.1mv and be that ligation successfully indicates (it is superseded that the S-T section does not have the changer) more than the lasting 0.5h.10min recording ecg is once more cut off ligature behind the ligation 30min after the ligation, realizes perfusion again, and record pours into electrocardiogram(ECG at once again, removes in the thoracic cavity layer-by-layer suture wall of the chest behind the hematocele, removes respirator, animal recovery autonomous respiration, and incision of trachea does not process.Irritate again at once, 10min, 20min, 40min, 1h, 2h, 3h recording ecg respectively.With heart after refrigerator and cooled is frozen 10min, from the apex of the heart entad the parallel coronary sulcus direction in the end 5 of equal thickness are cut in left chamber, put into the 1%TTC dye liquor, 37 ℃ of dyeing 10min, the necrotic area is not a garnet, the necrotic area is pearl.Digital camera is taken pictures.Weighed respectively in necrotic area and non-necrotic area, calculate the per-cent that the necrotic area accounts for left ventricular mass, i.e. infarction size.

Research to the provide protection of intraluminal middle cerebral artery occlusion in rats ischemical reperfusion injury
Experimental technique:
Animal random packet: blank group, Radix Salviae Miltiorrhizae Injection group, the application's red sage root A magnesium injection preparation group.The continuous tail intravenously administrable of each dose groups 3 days was processed middle cerebral artery occlusion (MCAO) model with improvement line bolt method in 20 minutes behind the 4th day medicine.Behind the rat anesthesia, it is fixing that it is lain on the back.Separate right carotid (CCA), internal carotid artery (ICA) and external carotid artery (ECA), ligation ECA and CCA, close the ICA distal end with the bulldog clamp folder after; Make a kerf in ECA and ICA crotch rapidly; Insert the nylon wire (diameter is 0.25mm, and 18mm marks at the place apart from the pommel, is stained with heparin solution before the insertion) that an end is heated into smooth, spherical and has been coated with 0.1% poly-lysine; Depth of penetration is 18mm, realizes that middle cerebral artery occlusion causes cerebral ischemia.Ligation ingress, nylon wire are stayed about 1cm, skin suture outward.Lift extremely slightly resistance of institute's the end of a thread that stays after 2 hours gently, realize that arteria cerebri media pours into again, modeling is accomplished.At ischemic 2h with pour in the 1h body temperature of keeping rat with electric blanket again, body temperature maintains 36.5~37.5 ℃ of anus temperature.The animal inclusion criteria is pressed Longa Pyatyi point system, gets the neural function behavior scoring and be 1,2,3,4 minute animal, (0 minute: the impassivity defective symptom; 1 minute: the offside forelimb can not stretch fully; 2 minutes: to sideway swivel; 3 minutes: topple over to offside; 4 minutes: can not oneself walk or stupor).The cerebral infarction scope is measured, and rat model pours into 24h again, after the study of behaviour scoring; Broken end is got brain, removes olfactory bulb, cerebellum and low brain stem, and remainder is at-20 ℃ of freezing 10min of refrigerator; Crownly on ice pan be cut into 6; Rapidly the brain sheet is placed the TTC dye liquor, 37 ℃ of lucifuge temperature are incubated 1h, take out to be placed on the 24h that keeps in Dark Place in 10% formalin.The non-ischemic region in dyed back is a rose, and infarct is a white.White organized carefully to dig down weigh, account for full brain weight per-cent as the cerebral infarction scope with blocking tissue's weight.
Brain water content is measured: after TTC dyeing is weighed, brain placed oven dry 12h claims dry weight in 120 ℃ of vacuum driers.Brain water content=(brain weight in wet base-brain stem is heavy)/brain weight in wet base * 100%.Experimental result sees table 4 for details.The influence of table 4 pair intraluminal middle cerebral artery occlusion in rats ischemical reperfusion injury rat cerebral infarction scope and brain water content (X ± S)
