ABSTRACT
【Objective】 To explore the basic situation and advantages of blood banks in Russia through analyzing the differences and similarities of basic standards for blood banks(referred to as standards) between China and Russia. 【Methods】 The main differences and similarities were analyzed by comparing the classification of blood banks and the requirements for staff and equipments. 【Results】 The macro contents such as the main functions and responsibilities of blood banks, the basic requirements for staff and equipments were both described in the standards in China and Russia, but such details as classification criteria of blood banks, the allocation criteria of staff and equipments were not the same. 【Conclusion】 The macro contents of the standards in China and Russia were basically the same, but some of the details of Russia standards were more clear and scientific than those of Chinese standards, and some contents were worth learning.
ABSTRACT
Objective To investigate the practical application values of copper sulfate method and hemocyte analyzer in blood do‐nation screening .Methods A total of 1 500 blood samples of donors were randomly collected and determined by using both copper sulfate method and hemocyte analyzer .Taking hemocyte analyzer as the reference method ,the sensitivity and specificity of copper sulfate method for detecting hemoglobin(Hb) were calculated .The overall detection rates of abnormal blood samples determinded by the two methods were calculated ,as well .Statistical comparisons were performed on the test data from both methods .Results A total of 29 donors(accounted for 1 .9% ) with unacceptable Hb value were found by using copper sulfate method .For all blood do‐nors ,the sensitivity and specificity of copper sulfate method for Hb screening before blood donation was 99 .7% and 82 .8% ,respec‐tively .And there were no statistically significant differences in sensitivity and specificity between the two methods for Hb estima‐tion(P>0 .05) .There were 336 donors with abnormal blood samples detected by using hemocyte analyzer .Taking hemocyte analy‐zer as the reference method ,only 8 .6% of donors with abnormal blood samples were screened out by using copper sulfate method . Conclusion The copper sulfate method could be used for Hb screening before blood donation .While because of its limitations ,such as relatively low specificity and inadequate screening items ,the hemocyte analyzer shoud be utilized before blood donation if the con‐ditions permit .
ABSTRACT
Objective To explore the effect of ginseng co?enzyme Q10 suncream on the skin damage caused by ul?traviolet ( UV) radiation in mice. Methods 36 mice were randomly assigned to four groups. The mice were shaved on the back and the left untreated side was taken as control group, or was treated with UV as model group. Before treated with UV, the mice were painted with suncream containing ginseng co?enzyme Q10 , or octyl methoxycinnamate as positive con?trols. The mice were treated for 8 weeks. At the end of the experiment, blood samples of all mice were collected from the eyes, then subjected to cell counting or biochemical measurements, and skin samples were cut for pathological examina?tion. Results Compared with the control group, there was a significant increase in white blood cell counts ( P<0?05 ) and MDA content ( P<0?05 ) , and declined serum levels of SOD ( P <0?05 ) and GSH?Px ( P <0?05 ) in the model group, and the skin was rough and wrinkled with stratum corneum exfoliation. Compared with the model group, the mice of ginseng co?enzyme Q10 suncream group had significantly lower white blood cell count ( P<0?05 ) and MDA content ( P<0?05), and increased serum levels of T?SOD(P<0?05) and red blood cell counts (P<0?05). The skin had no rough? ness and wrinkles and without stratum corneum exfoliation. Compared with the model group, the positive control group showed significantly decreased white blood cell count (P<0?05) and MDA content (P<0?05), and increased serum lev?els of GSH?Px(P<0?05). The skin had no roughness and wrinkles and no stratum corneum exfoliation. However, there was no significant difference between the ginseng co?enzyme Q10 suncream group and positive control group. Conclusions Ginseng co?enzyme Q10 suncream shows satisfactory preventive effects on the UV radiation?induced skin damage in mice, similar to the preventive effects of the octyl methoxycinnamate?containing sunsream.
