[Effects of zuzhongping on ischemic volume in the rat model of middle cerebral artery occlusion]. 1994

Z Luo, and S Liu, and G Yuan

Using the middle cerebral artery occlusion model, we studied the effects of Zuzhongping on experimental focal cerebral ischemia. Twenty-eight adult male Wistar rats were randomly divided into three groups: (1) Zuzhongping group (n = 9), (2) Saline control group (n = 10), and (3) Blank control group (n = 9). Group 1 and group 2 received via a gastric tube 1 1ml/kg/day of Zuzhongping and normal saline, respectively. The cerebral middle arteries on the right side of 28 rats were occluded with a bipolar electro-coagulater at sites 1-2 mm from the right olfactory nerve tract. Ischemic volumes were measured by an image analytic system when the cerebral ischemia had lasted 24 h. The results showed that the ischemic volume of Zuzhongping group was significantly smaller than that of group 2 and group 3, suggesting a protective effect of Zuzhongping.

D011897	Random Allocation	A process involving chance used in therapeutic trials or other research endeavor for allocating experimental subjects, human or animal, between treatment and control groups, or among treatment groups. It may also apply to experiments on inanimate objects.	Randomization,Allocation, Random
D001921	Brain	The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM.	Encephalon
D002545	Brain Ischemia	Localized reduction of blood flow to brain tissue due to arterial obstruction or systemic hypoperfusion. This frequently occurs in conjunction with brain hypoxia (HYPOXIA, BRAIN). Prolonged ischemia is associated with BRAIN INFARCTION.
