High-resolution computed tomography of the mammalian lung.

High-resolution computed tomography (HRCT) was performed in 21 isolated animal lungs, from 4 mammalian species (pigs, rabbits, dogs, sheep). Gross and subgross central and peripheral lung morphology was determined by HRCT. Three distinct types of lungs can be identified, principally based on the extent of interlobular septal development; the relationship of major vessels to airways; and the thickness of the visceral pleura. Type-I lung is found in pigs, sheep, and cattle; type-II lung is found in rabbits, dogs, cats, and monkeys; and type-III lung is found in human beings and horses. These mammalian lungs were compared with human lungs. The potential use of HRCT to investigate specific human lung diseases in the aforementioned species also was considered.     

乳酸杆菌制剂对肉仔鸡肠道菌群、血清球蛋白及生产性能的影响

120只1日龄艾维茵肉仔鸡饲喂不同水平乳酸杆菌制剂,研究乳酸杆菌制剂对肉仔鸡的饲喂效果。结果表明,乳酸杆菌制剂在提高肉仔鸡成活率、增重和改善饲料利用率方面有一定的促进作用,但效果不显著(P>0.05)。而在改善肠道菌群结构和提高血清球蛋白方面效果显著(P<0.05)。     

川北地区稻田养殖中华绒螯蟹试验初探

本试验在四川山间湿地利用农田0.62公顷养殖中华绒螯蟹，放养苗种为1272只(135只／667m^2)，个体均重7g／只左右，经160d饲养，捕获绒螯蟹875只，个体均重136．7g／只，回捕率为68.8％，饵料系数为2．45，同时水稻产量3529．7kg(375．5kg／667m^2)，其总收获利润为416元／667m^2。     

羔羊全营养代乳粉对羔羊增重影响的试验

为了研究羔羊出生后采取人工饲喂代乳粉溶液的效果，对10日龄羔羊称重，以平均日增重与母乳组比较，用t检验方法检验差异显著性。研究结果显示羔羊平均日增重试验组为0.097-0.126kg，母乳组为0.071-0.113kg，二者没有显著差异。在生产中，代乳粉能替代绵羊母乳饲喂羔羊，对多胎品系羊的推广应用以及解决绵羊缺乳、少乳或无乳问题具有重要意义。     

Significance of CD117 and CD34 expression in gastrointestinals tromal tumors

AIM:In this article,gastrointestinal tumo r-related historical ar chives of pathology in our hospital were reviewed in order to acknowledge gastro intestinal stromal tumors (GIST).METHODS:These cases were rediagnosed correctly ,these tissues were labeled with some antibodies such as CD117,CD34,α-SMA,S-100,and the ir clinical characteristics were explored.RESULTS:CD117,CD34 were expressed widely in GISTs ,the percen tage of positive expression was CD117 （50/56,89.3%）,CD34 （37/56,66.1% ）,respectively,α-SMA,S-100 were （17/56,30.4%）,（4/56,7.1%）,re spe ctively,desmin was negative in these cases.Among them,29 cases were benign a nd borderline,27 cases were malignant.The percentage of occurring in stomach a nd intestine was 91.1%.CONCLUSION:CD117,CD34 are expressed significantly in GIST,t hese might be assistant markers for GIST diagnosis.GISTs mostly occurred in sto mach and intestine.
