Above all, Staphylococcus aureus, Streptococcus agalactiae, and Escherichia coli are the main pathogens causing bovine subclinical mastitis; the bovine clinical mastitis is usually caused by Streptococcus agalactiae. Antibiotics such as Enrofloxacin, Erythromycin and Kita sermonic show effective on treatment; the preparation of Chinese traditional medicine has great potential on bovine mastitis treatment and should be widely spread.

Results ①Five days after abdominal application of Xiaoji power(0.1 g per mouce),the medicine showed a very significant effect in enhancing gastrointestinal propulsive function.② Xiaoji powder not only had relaxing effect on the normal smooth muscle in vitro,but also had a strong spasmolytic effect on acetylcholine,green bariuminduced spasm of intestinal smooth muscle.The experiment was based on 10 μg atropine sulfate as a positive control to carry out control experiments.It showed the graphics of atropine sulfate in spasmolytic role.③Xiaoji powder navel paste therapy played a positive role in adjusting the gastrointestinal electric disorder caused by deficiency of spleen Qi,and could restore it to its normal state.

结果 （1）以0.1 g/只消积散给予小鼠腹部用药5 d，即显示非常显著的增强胃肠推进功能作用；（2）消积散不仅对正常离体平滑肌有舒张作用，同时对由于乙酰胆碱、氯化钡引起的肠平滑肌痉挛也有强的解痉作用，该实验是以硫酸阿托品10 μg作为阳性对照药进行对照实验，显示了硫酸阿托品的解痉作用图形；（3）消积散敷脐对脾虚引起的胃肠电紊乱有明显的调节作用，使脾虚大鼠的胃肠电基本恢复到正常状态。

It was found that 0.25%o potassium sorbate produced a positive inhibition against short G+ spore bacillus with a concentration less than 5xl04cfu/ml. A concentration less than %o potassium sorbate hardly exerted a complete control towards short G- plump bacillus having a population density of 5x104cfu/ml. It was proved that use of l% potassium sorbute never controlled the growth of G+ coccus, G~ spirilla and enterobacter with a population density of 104cfu/ml. 1mmol EDTA completely controlled the growth of G+ short spore bacillus and G+ coccus whose cell density was 5xl04cfu/ml. A level of lmmol EDTA showed a limited inhibition against the growth of G- spirilla with a population density of 105 cfu/ml. However, a level of 10mmol EDTA completely controlled the growth of the G- spiral bacteria having a population density of 105cfu/ml. lOmmol EDTA produced a very significant control towards the growth of G"" plump short bacillus with 105cfu/ml. 20mmol EDTA showed a remarkable inhibition against the enterobacter with a population density of 105cfu/ml. Different concentrations of nisin including 25mg/mL, 50mg/mL, 75mg/mL and 100mg/mL were used as bio-preservative to examine its effects against the growth of all strains leading to the spoilage of fresh mutton meat. It was seen that there was a big difference in nisin's concentrations in inhibiting the spoiling bacteria. Generally speaking, as more as 75mg/mL of nisin significantly inhibited the growth of G+ short spore bacillus, G-plump short bacillus, enterobacter, G'spiral bacteria and G+ coccus having a population density of 105cfu/ml.

分别运用山梨酸钾、EDTA和Nisin对7种主要引起羊肉腐败的微生物进行了抑菌实验，结果显示，0.25‰以上山梨酸钾能够有效抑制5×10~4 cfu／mL以下的革兰氏阳性短芽孢杆菌的生长；1‰以下的山梨酸钾不能完全抑制5×10~4 cfu／mL革兰氏阴性粗短杆菌的生长，对10~4 cfu／mL革兰氏阳性球菌菌株、革兰氏阴性螺旋菌菌株和肠杆菌菌株抑制效果不太明显。1mmoL EDTA能完全抑制住小于10~5 cfu／mL革兰氏阳性短芽孢杆菌菌株、革兰氏阳性球菌菌株的生长，能明显的抑制10~5 cfu／mL的革兰氏阴性粗短杆菌菌株生长，对10~5 cfu／mL的革兰氏阴性螺旋菌菌株有一定的抑制作用。10mmoL EDTA能完全抑制住10~5 cfu／mL革兰氏阴性螺旋菌菌株的生长；能明显抑制10~5 cfu／mL的革兰氏阴性粗短杆菌菌株的生长，而20 mmoL EDTA能很明显抑制10~5 cfu／mL肠杆菌菌株的生长。25mg／mL、50 mg／mL、75 mg／mL和100 mg／mL的Nisin几乎对所有引起羊肉的腐败菌有抑制作用，但抑制程度不同，抑菌活性有一定的变化。

On the normotensive rat, bilateral microinjection of L-arginine (16 n mol/0.1 ul/site), a precursor of nitric oxide into the rVLM, caused a decrease in BP, HR and the pressor response induced by the dPAG stimulation, while microinjection of NG-methyl-Larginine (L-NMMA, 16 n mol/0.1 ul/site), a blockade for NO to form, into the rVLM bilaterally, caused an increase in BP, HR and the pressor response induced by the dPAG stimulation. There was no effect of both drugs mentioned above on the tachycardiac response induced by the dPAG stimulation.

五、在正常血压大鼠，于双侧rVLM微量注射一氧化氮前体(16nmol/0.1μl/site)可引起BP降低、HR减慢、以及电刺激dPAG诱发的防御性升压反应减弱；而于同区微量注射生成一氧化氮的拮抗剂N〓-甲基-L-精氨酸(16nmol/0.1μl/site)则可引起BP升高、HR加快、以及电刺激dPAG诱发的防御性升压反应增强；而上述两药对电刺激dPAG诱发的防御性加快心率反应均无明显作用。

Animals, as material, were used to study the toxicity of outer substance and made sure the estrogen effect of BBP by whole animal experiment, and the chronic toxicity of BBP was studied, designed and valued through several dosages and different exposed time. The result showed that BBP could make testis, epididymis and prostate withdrawl. Tectology changes were observed in testis, epididymis and liver. Especially the atrophy and degeneration of seminiferous tubules, decrease of spermatogenic cell and the turbulence of Sertoli cell and spermatogenic cell of seminiferous epithelium were also observed. The linkage between cells vanished.
