Changes of carbohydrate contents, sucrose-metabolizing enzymes activities and chloroplast ultrastructure in tomato（ Lycopersicon esculentum Mill.）leaves that were treated by 30 ℃ and 35 ℃ were studied to investigate the effects of high temperature on carbohydrate metabolism of tomato. Plants were treated by 30 ℃ and 35 ℃ in daytime after the 1st inflorescence effloresced, and plants that under 25 ℃ were considered as control.

Results: NKA-I cells was first found in the duodenum mucose on the 14th day of fetus, earlier than in the jejunum ( 16th day ) and ileum ( 17th day ), and its Positive reaction and the number of cells increased with further development, after birth the 30th day, it became quite identical to that of adult rat; NKA-I cells were seen in the colon mucosa on the 17th day of fetus, later on the number kept decreasing till grown up stage; No change was observed in the stomach mucosa except that few cells showed up on the 15th day of fetus; No positive cell was found on the oesphagus wall.

结果：NKA-I细胞首先见于胚胎14 d的十二指肠粘膜，早于空肠(胚胎16 d)和回肠(胚胎17 d)，其阳性反应强度及细胞数量随发育而增加，30 d时与成年鼠相似；结肠粘膜内于胚胎17 d见多个细胞，但此后数量较少直至成年；胃粘膜于胚胎15 d见个别细胞外，以后无明显变化；食道壁始终未见阳性细胞。

Methods:Using dogs as experimental objects,we ligated one side of carotis extern al artery and occipitalis artery.Electromagnetic flowmeter was used to measure t he blood flowing volume of carotis artery;polygraph system was used to investigate the change of blood pressure,ECG and heart rate.

以犬为实验对象，结扎一侧颈外动脉及枕动脉，以电磁流量计测颈动脉血流量，用多道生理记录仪记录血压、心电图及心率的变化。

MAIN OUTCOME MEASURES: Morphological changes in primary cultured and subcultured mouse BMSCs were measured. BMSC surface antigen of the second passage of mice (CD105, CD44, CD25, CD34) were determined using flow cytometry. The modified method was assessed to harvest the purity of stem cells. Activity of mouse BMSCs was identified using adipogenic and osteoplastic differentiation. The strength of fluorescent cells following multiple passage was observed.
