查询词典 irradiation

Five minutes is the optimal irradiation time for ALA-PDT by Xe lamp under the same irradiation conditions. Irradiation injury caused by the light alone was slight, but the destruction rate of ALA-PDT was very high. Conclusion: Xe lamp's action spectrum is wider and it's power is higher, so it's better than 532 nm laser for ALA-PDT.

结果：532 nm连续激光和脉冲激光对K562细胞的ALA-PDT抑制率均较低，增加光剂量也不能有效提高ALA-PDT的抑制率；氙灯在功率密度为350 mW/平方公分、光照5 min时就能达到最佳的光剂量，此时单纯光照对K562细胞的光损伤作用很小且ALA-PDT效率很高。

In the combined treatment of the craniopharyngiomas, it is very important to prevent the irradiation injury of the surrounding structures such as the optic nerve, chiasm, hypothalamus and vascular structures. In those structures, the optic nerve and chiasm are the most sensitive ones to the irradiation, and their ability to bear the irradiation is about 9 to 12 Gy. So if the irradiation dose is lower than 9Gy, the treatment will be safe. We have not found any report about the bearability and side effect of the hypothalamus related to the gamma knife radiosurgery.

在治疗过程中，预防病变周围的重要结构如视神经，视交叉，丘脑下部和血管结构的放射性副损伤是非常重要的，在这些重要结构中，视神经和视交叉对放射线最为敏感，其耐受能力约为9～ 12 Gy，因此如果对这些结构的放射剂量在9Gy以下，治疗将是安全的，目前尚无有关丘脑下部的耐受剂量和放射性损伤的文献报道。

Aim To investigate the production and removal of cyclobutane pyrimidine diners after UVB irradiation and the effect of baikal skullcap root, szechwan lovge rhizome and epigallocatechingallate on the irradiation damage in HaCaT cells, and finally, to clarify the probable regulatory mechanisms. Methods HaCaT cells were cultured in RMPI-1640 medium with 10% fetal bovine serum. The time and dosage of UVB irradiation were conducted according to the experimental design. Tested medicines were added into the medium before or after UVB irradiation.

It is observed that after irradiation, the detectors' peak and cutoff wavelength move towards short wavelength; the room temperature resistance and current responsivity become decreasing when irradiation dosage is larger than 10 15/cm 2; the detectivity doesn't show a monotonical change owing to the influnce of noise.

在辐照剂量大于1015/cm2时，器件的室温电阻和响应率明显下降。探测率由于噪声的影响无明显变化趋势。标签碲镉汞光导型探测器电子辐照辐照效应 HgCdTe photoconductive detectors electron irradiation radiation effects

The results showed that the irradiation treatment in the dose of 2.0-8.0kGy is not significantly effective to the contents of total sugar, crude protein and crude fat in walnut powder. The content of crude fiber in irradiated walnut powder increased, but not significantly. The irradiation had barely change on the contents of the lauric acid and myristic acid, and non-significant effects on the contents of palmitic acid, palmitoleic acid, stearic acid, leinoleic acid, arachidic acid and linolenic Acid. However, the irradiation contributed to significant increase in the content of oleic acid with the irradiation dose. When irradiation dose reached 8.0kGy, the content of oleic acid had an increase of 4.3%. Irradiation will not change the sensory index of walnut powder much when irradiation dose is lower than 8.0kGy.

结果表明：剂量为2.0～8.0kGy时，辐照对核桃粉中的总糖、粗蛋白和粗脂肪含量无显著影响；辐照后的粗纤维含量有一定的增加，但不显著；辐照对核桃粉中的月桂酸和肉豆蔻酸含量基本没有影响，对棕榈酸、棕榈油酸、硬脂酸、亚油酸、花生酸和亚麻酸含量有一定的影响，但不显著；辐照后核桃粉中的油酸含量随辐照剂量的上升而显著增加，剂量达到8.0kGy时，油酸含量增加了4.3%。8.0kGy以下辐照对核桃粉色泽、气味、口感无明显改变。

Methods Six weeks old male Fischer 344 rats (F344) were used as donors, and six weeks old male F344alb as recipients. All F344alb were divided into 4 groups: group Ⅰ(n=10) was untreated; group Ⅱ(n=10) was treated with CCl4 but no γ-irradiation and transplantation; group Ⅲ(n=10) was transplanted with 1×10^7 BMCs after γ-irradiation, but without CCl4 treatment; group Ⅳ(n=10) was transplanted with 1×10^7 BMCs after γ-irradiation, with CCl4 treatment. The BMCs prepared from the donors were infused via the penial veins of recipients immediately after whole body γ-irradiation (7.5Gy) and CCl4 treatment: 4 weeks after BMCs transplantation, CCl4 were injected into peritoneal cavity twice a week for 4 weeks.

雄性F344大鼠为供体，而雄性F344alb为受体，分为4组：组Ⅰ(n=10)为正常对照组，不接受肝损处理，无全身射线照射和阴茎静脉骨髓细胞移植；组Ⅱ(n=10)为肝损无移植组，只接受肝损处理，无全身射线照射和阴茎静脉骨髓细胞移植；组Ⅲ(n=10)为正常移植组，全身射线照射后阴茎静脉移植骨髓细胞1×10^7；组Ⅳ(n=10)为肝损移植组，接受CCl4注射肝损，全身射线照射后阴茎静脉骨髓细胞移植1×10^7BMCs，其中，γ-照射剂量为7.5Gy，F344大鼠的BMCs经受体的阴茎静脉注入。

The results showed that there were differences among treatments in transformation of high quality gene(Glu\|D 1 5+10) in F 1 grains, and heterozygous type was more frequently appeared in the treatment of irradiation. In the F 2 segregative population, heading date deviated to early\|mature parent in the treatment of reciperocal cross and its combination with irradiation, indicating that cytoplasm and irradiation could promote the heading. In F 3 the expressive frequency of (5+10) gene in the cross was lower than that in reciperocal cross, and irradiation treatment could raise the expressive frequency of(5+10) gene. These results showed varience in different crosses.
