Background and Objective: The size of the human body is studied in anthropometry. In the one field of anthropometry, the relation of skull and brain size with body weight and height in human are studied. This study was done to determine the relation between cranial capacity and brain weight with body weight and height in 18-26 years old Iranian students. Methods: This cross-sectional study was done on 286 students (150 females and 136 males) in Arak, Iran. Cranial capacity, brain weight, body weight and height, cerebral index and the ratio of brain to body (cerebral quotient) in 18-26 years old students were measeared. Results: The mean of cranial capacity in males and females were 1393.71 and 1168.71 mm3, respectively (P<0.05). The mean of brain weight in males and females were 1445.19 and 1209.61 gram, respectively (P<0.05). The mean of cerebral index in males and females were 1.99 and 2.2, respectively (P<0.05). Positive statistical correlation was seen between cranial capacity with body weight, height and BMI in both gender. Conclusion: Cranianl capacity and brain weight in males was more than females while cerebral index was more in females.

Background and Objective: Listeria monocytogenes is a gram-positive facultative intracellular non spore forming bacillus. The epidemiologic studies have shown that Listeria monocytogenes is the cause of abortion and abnormalities in human embryo. This study was done to determine the effect of listeria monocytogenes colonization on maternal and fetal liver and spleen in mice. Methods: In this experimental study, Inbred BALB/c dams allocated into case and control groups. Dams in interventional and control groups were received 200µL of 1.2 LogFCU/ml, Listeria monocytogenes and normal salin intraperitoneally, respectively. Few mice from each group were randomally selected and 5ml of blood collected, placenta, uterus liver and spleen were removed subsequently in 13 and 24 day of gestation and listeria monocytogenes colonization were determined. Liver and spleen of full term offsprings were stained for the histological studies. Results: L.monocytogenes strains were detected in different organs of mice damsup for 30 day of gestation. The higest and lowest of organ contamination were seen in liver and blood samples, respectively. The ratio of weight/volume of organ was higher in case than control groups. Hepatocytes degenration, hepatocyte size alteration, cell cord atrophy and sinusoid dilatation were seen in the liver. Disruption of red pulp, disorganization of lymphoid nodules and necrosis were noticed in the spleen. Conclusion: Contamination of BALB/c dams causes the histological alterations in the liver and spleen of offesprings.
