ABSTRACT
Cranial capacity and brain weight are important measurements in the study of racial/ethnic differences. Using linear (LeePearson's) formula, brain weight and cranial capacity were estimated in 398 normal 17 to 20-year-old males (200 native Fars and 198 Turkman) males in Northern Iran. The dimensions of the head measured with spreading caliper and auricular head spanner. The mean±S.D of brain weight and cranial capacity in native Fars males were 1343.45±102.37 cm3, and 1390.47±105.95 g, and that of Turkmans were 1163.02±115.76 cm3 and 1203.73±119.81 g, respectively. Cerebral Index was 3.40 ±0.37 % and 2.52 ±0.37 % in Native Fars and Turkmans, respectively and cerebral quotient was higher in Turkmans (8.34) than Native Fars males (7.95). This study showed, the effect of ethnic factor influences the brain weight of 17-20 year-old males in Northern Iran.
La capacidad craneal y el peso del cerebro son mediciones importantes en el estudio de las diferentes etnias. Se estimó el peso del cerebro y la capacidad craneal usando la fórmula lineal de Lee-Pearson, en 398 hombres de 17 a 20 años de edad (200 nativos Fars y 198 Turcomanos) en el norte de Irán. Las dimensiones de la cabeza se midieron con caliper deslizante y con una llave de Todd, para la medición auricular. La media ± D.S. del peso del cerebro y la capacidad craneal en hombres nativos Fars fue de 1343,45±102,37 cm3, y 1390,47±105,95 g, y la de los turcomanos fue de 1163,02±115,76 cm3 y 1203,73 ± 119,81 g, respectivamente. El índice cerebral fue de 3,40± 0,37 % y 2,52 ± 0,37 % en nativos Fars y turcomanos, respectivamente, y el cociente cerebral fue mayor en los turcomanos (8,34) que en los hombres Fars (7.95). Este estudio demostró que el efecto del factor étnico influye en el peso del cerebro en hombres de 17-20 años del norte de Irán.

Objective To investigate the effect of Shuluo Injection on cerebral water volume,cerebral index ,LDH,NOS and SOD in the brain.Methods The model of cerebral ischemia-reperfusion in mice is set up by separating the bilateral common carotid artery (CCA) of the mice,blocking the blood stream by straining the thread and by reperfusion loosing the thread. After 3 times of ischemia-reperfusion,brain samples were prepared to observe the cerebral injury. Results High-dose Shuluo Injection significantly reduced the cerebral water volume and decreased the cerebral index and the activity of LDH and NOS(P
ABSTRACT
AIM: To study the protetive effects of Danshenhonghua Injection (Radix Salviae Miltiorrhizae,Stigma Croci,etc) on acute cerebral ischemia in rats. METHODS : The model of acute incomplete cerebral ischemia was built by ligaturing bilateral carotid arteries. Cerebral index,cerebral water content ,capillary permeability of brain,and the change of cerebral morphology in rats were observed. RESULTS : The cerebral index,cerebral water content,capillary permeability of brain decreased remarkably with 7.2,14.4mg?kg -1 of Danshenhonghua Injection,and the injury of brain tissue was also abated by Danshenhonghua Injection significantly. CONCLUSION : Danshenhonghua Injection has the protetive effects on acute cerebral ischemia.
