Methods The cognitive impairment rat model was induced by hypodermic D-galactose injection and half fat feeder (6 weeks), the Morris water maze was used to screen the model rats, which were divided randomly into 4 groups (12 rats in each group): the model group, the hydrochloricdonepezil group (0.4 mg/kg, weight, sic passim), the low-dose Huannao Yicong Fang group (7 g crude drug/kg), the high-dose Huannao Yicong Fang group (14 g crude drug/kg), they were treated respectively by intragastric administration. Besides, a control group of 12 rats was set up, they were given tales doses of distilled water. After 4 weeks, the behavior of the rats was detected, the contents of plasma P-selectin and PAI-1 were measured by ELISA, also the hemorrheology was measured.

Iba 2002. Both the Arabidopsis fad5 mutant, which lacks an active chloroplast x-9 fatty acid desaturase and accumulates high levels of palmitic acid (16:0), and the fad6 mutant, which lacks an active x-6 fatty acid desaturase and accumulates high levels of palmitoleic acid (16:1) and oleic acid (18:1), have reduced levels of polyunsaturated fatty acids in the chloroplast galactolipids.

两个拟南芥突变体的叶绿体半乳糖脂含有较少的多不饱和脂肪酸：一种是拟南芥fad5突变体，它缺乏有活性的叶绿体的X-9脂肪酸去饱和酶，因而积累了高浓度的棕榈酸（ 16：0 ）；另一种是拟南芥fad6突变体，它缺乏一个有活性的 X - 6脂肪酸脱氢酶因而积累了高浓度的软脂酸（ 16：1 ）和油酸（ 18：1 ）。

These uncontaminated explants showed that morphogenetic potential were 70%-75% and each responding explant had 1.2-1.4 shoots formation on MS medium supplemented with 2 mg/L NAA and 16 mg/L BA. Moreover, adding antibiotics (100 mg/L Rifampicin and 100 mg/L Gentamycin) to solidify MS contained 3% galactose were tested, results showed the lowest contamination rates were 20% and 1.0-1.2 shoots were regenerated per responding explant. The antibiotic treatments with 100 mg/L Rifampicin and 100 mg/L Gentamycin could reduce internal contaminants, while the addition of antibiotics into medium in vitro culture led to phototoxic phenomena of axillary explants, morphogenetic potential lost and the growth of regenerant was also inhibited.

以100 mg/L Rifampicin+100 mg/L Gentamycin或100 mg/L Rifampicin+100 mg/L Gentamycin+150 mg/L Streptomycin组合浓度处理者，具有显著降低污染率的效果分别为60%及50%；克服内生菌污染而建立初代无菌培养之腋芽培植体，则以100 mg/L Rifampicin或以100 mg/L Rifampicin+100 mg/L Gentamycin处理者，芽体再生率最高70%-75%，惟平均每一腋芽培植体芽体增殖数仅1.2-1.4个；另在醣种类及浓度与抗生素试验，显示100 mg/L Rifampicin+100 mg/L Gentamycin之抗生素浓度组合添加至含3g/L半乳糖的培养基，显著降低污染率至20%；但未污染之培植体，形态发生潜能低至40%以内，可反应生长之培植体芽体形成数也仅达1-1.2个之间，再生芽体之生长也显现抑制现象。
