BACKGROUND: Changes of elastic fibers in middle cerebral artery(MCA)is close related withthe aged cerebrovascular disease.OBJECTIVE: To observe the changes of elastic fibers of MCA in different aging rats.DESIGN: A descriptive and controlled study based on experimental animals.SETTING: Department of anatomy and central laboratory in a university.MATERIALS: Totally 36 healthy Wistar rats with either gender, weighing 200 - 280 g, were selected from the Animal Institute of the third medical military university of Chongqing[certification SCXX (army) 2002-007].INTERVENTIONS: Changes of elastic fibers of MCA of different aging rats were observed with light microscope, transmission electron microscope and image analysis system. MAIN OUTCOME MEASURES: ①) Major outcome: changes of elastic lamella in MCA of different aging rats; ②) Secondary outcome: ultramicrostructural changes of internal lamella under the transmission electron microscope. RESULTS: With the increase of age, the folded extent and quantity of internal elastic lamella were decreased, and the content of elastic fibers were also decreased significantly( P < 0.01 ). However, the ratio of collagen fibers to elastic fibers was increased significantly( P < 0.01 ) . In the aging group above 24 months, the internal elastic lamina thinned, delaminated and disrupted, and the lipid deposited in it. Endothelial cells and smooth muscle cells passed through the internal elastic lamina. CONCLUSION: Changes of elastic fibers may be related with the increased susceptibility to the cerebrovascular disease in aged people.

OBJECTIVETo verify the pharmacological hypothesis of prescriptions by studying the targeted distribution of major components in stewed rhubarb in the rat model with acute pancreatitis (AP).
METHODNormal SD rats (control group, n = 5) and the AP model induced with intraperitoneal cerulein (model group, n = 5) were taken as the experimental objects. Rats of the two groups were orally administered with stewed rhubarb granules (20 g x kg(-1)). Their heart, liver, spleen, lung, kidney and pancreas were collected two hours after the administration. Such constituents as emodin, chrysophanol, physcion, rhein and aloe-emodin and their concentrations in each tissue homogenate were detected by high performance liquid chromatography-mass-mass.
RESULTAloe-emodin and physcion in stewed rhubarb whose concentrations in liver and kidney of normal rats were higher than that in pancreatic tissues, while the distribution spectrums and concentrations of the remaining components in pancreatic tissues had no significant difference with that of other organs. The concentrations of emodin, aloe-emodin, rhein and chrysophanol in stewed rhubarb in pancreatic tissues of the AP model group were higher than that in other tissues and organs, while their concentrations in pancreatic, renal and splenic tissues were notably higher than that in the normal group.
CONCLUSIONIn the conditions of AP, effective components in stewed rhubarb show a targeted distribution feature in pancreas, which provides experimental basis for the pharmacological hypothesis of prescriptions.
