    ABSTRACT: Spleen is one of the secondary or peripheral lymphoid organs along with cecal tonsils in birds. The growth of the spleen of Gallus Domesticus (deshi chicken) from prenatal embryonic day fifteen (ED15) to postnatal day ninety (D90) were studied. In macroscopic study it was found that the shape of the spleen was rounded with slightly flattened from side to side at its middle part at prenatal period (ED15, ED18) and becomes rounded at postnatal stages of the deshi chicken (D90). Regarding position it lies close to the right side of the junction between proventriculus and gizzard and was similar in prenatal and postnatal stages. The result of the present study revealed that the mean diameter and weight of the spleen in deshi chicken gradually increases with increase of age, which were 2.00+/-0.136mm and 0.007+/-0.00gm respectively at ED15 stage and it reaches upto 10.40+/-0.331mm and .303+/-0.004gm respectively at day 90 (D90). It was observed that the differences of diameter & weight of the spleen between different ages were statistically significant (p<0.01). Histologically the spleen was surrounded by thin capsule in prenatal life, which gradually becomes thicker in postnatal life. The splenic pulps were not differentiated into white and red pulp on 15th day of embryonic life (ED15) but they were gradually differentiated into white and red pulp in the late prenatal (ED18) and postnatal period. The growth and development of spleen at each stage of the study period were found to be significantly high. Present study indicates that chicken splenic cell population, structure and function were similar to human spleen histologically. It was also found that the chicken embryo allows easy experimental access to all the stages of the splenic development, so the present study will be helpful for experimentation on lymphoid organs and to understand pathophysiology of immunological diseases of human.

    ABSTRACT: The aim of the present study was to establish the standard length of the normal spleen in Bangladeshi people. One hundred and twenty human cadavers of which eighty-seven male and thirty-three female were dissected to remove spleen with associated structures in the morgue of Forensic Medicine Department of Mymensingh Medical College. Collected specimens were tagged with specific identification number, divided into five groups according to age and height of the individual. Gross and fine dissections were carried out after fixing the specimen in 10% formol saline solution. Length of the spleen was measured by measuring tape and expressed in cm and findings of the present study were compared with the findings of national and international studies. This was a cross sectional descriptive study carried out in the Department of Anatomy of Mymensingh Medical College, Mymensingh. The mean length of spleen was maximum as 11.20 cm in male in group C (31-45 years), and as 11.80 cm in female in group B(16-30 years) and mean length of spleen was minimum as 10.06 cm in male and 9.53 cm in female in group A (upto 15 years). Difference between group A and B, A and C, A and D were statistically significant. There were no significant differences in between other groups. According to height of individual the mean length of spleen was maximum 11.42 cm in 165.01 to 180 cm height group and minimum 10.30 cm in 0-120 cm height group which indicate that length of the spleen increases with height of the individual. This was observed that length of the spleen depends on the age, sex and body height of the individual.

    ABSTRACT: The aim of this study was to establish the standard weight of the normal spleen in Bangladeshi people. One hundred and twenty human cadavers of which eighty seven male and thirty three female were dissected to remove spleen with associated structures. Collected specimens were tagged with specific identification number, and divided into five groups according to age, sex and height of the individual. Gross and fine dissections were carried out after fixing the specimen in 10% formal saline solution. Weight of the spleen was measured by analytical balance and expressed in gram and findings of the study were compared with the findings of national and global studies. This cross sectional descriptive study was carried out in the Department of Anatomy of Mymensingh Medical College, Mymensingh. In this study maximum mean weight of spleen was 86.35 gram in male and 85.33 gram in female in 31 - 45 years age group. Minimum mean weight of spleen was 47.37 gram in male and 38.83 gram in female up to 15 years age group. The weight of spleen increases with age of the individual. Mean weight of spleen in male was 73.43 gram, which was higher than the mean weight of female spleen (59.17 gram). According to height of individual the mean weight of spleen was maximum 84.32 gram in 165.01 to 180 cm height group and minimum in 54.87 gram in up to 120 cm height group which indicate that weight of the spleen increases with height of the individual. In conclusion, the weight of the spleen depends on the age, sex and body height of the individual.

    ABSTRACT: The morphological study was done to see the origin of right and left hepatic arteries supplying the liver and gallbladder in Bangladeshi people to increase the knowledge regarding variational anatomy in this region. Sixty post mortem tissue blocks containing liver and gallbladder along with surrounding structures were collected from 40 male and 20 female cadavers of different age groups and fixed in 10% formol saline solution. This was a cross sectional descriptive study. This study was carried out in the Department of Anatomy in Mymensingh Medical College, Mymensingh, from July 2007 to June 2008. Gross and fine dissections were carried out to study the different origin of right and left hepatic artery and its topographic relationship with adjacent structures. In the present study, findings were compared with the findings of Western researchers. In the present study, typical origin of the right and left hepatic artery from hepatic artery proper was 85% and in 15% cases it was found to arise from other sources. The right hepatic arteries those were not originated from hepatic artery proper, 8% was found to arise from common hepatic artery and 7% from superior mesenteric artery. But in case of left hepatic artery, remaining 15% was originated from common hepatic artery.
