Context: Stature is the height of the person in the upright posture. It is an important measure of physical identity. Interrelationships among different body measurements may be used to estimate one from another in case of missing body parts. As any part of the human skeleton can be found as the evidences, there arise a need to investigate whether there is any possible significant correlation between stature and any parts in human body. Garos, our study subject living in Bangladesh are usually recognized as an ethnic community, they have a separate identity and their physical appearance is distinctive to some extent. The present study was conducted with the intention to establish ethnic specific anthropometric data for the Bangladeshi Garo tribal populations and also to determine whether there is any correlation between the measured values of the stature and the physically measured cranial variables, to estimate (using respective multiplication factor) the stature from the physically derived cranial measurements and to assess the effectiveness of such estimation. Study design: The study was an observational, cross-sectional and descriptive in nature with some analytical components. Study settings and study period: The study was carried out in Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, during the session of January to December 2008. Selections of the subjects: A total number of one hundred Garo female subjects were included from Dhaka city and Mymensingh district. Methods: Cranial dimension such as head circumference, head length and stature were measured using a measuring tape, spreading caliper, steel plate and steel tape. Results: Head circumference showed significant positive correlation with stature but head length did not reach statistically significant level with stature. No significant difference was found between the ‘measured' and ‘estimated' stature for head circumference and head length. Key words: Anthropometry; stature; correlation; head circumference; head length DOI: 10.3329/bja.v7i2.6096 Bangladesh Journal of Anatomy July 2009, Vol. 7 No. 2 pp. 101-104

Background: Teaching and learning of Cell Biology and Histology have gone through remarkable changes in recent times. The undergraduate medical courses in Bangladesh have incorporated some of these changes but seem to have some more way to go. Good Histology books are supposed to be reflectors of the desirable changes and of the present trends in teaching-learning and assessment in the subject in good institutions. Analyses of the ‘Preface’s of these books can help in developing an insight into the approaches taken and means applied in presenting Cell Biology and Histology in the books for meeting the demands of time. This insight, in turn, would guide the curriculum planners of the country and others seeking for changes in taking necessary steps. Objectives: To analyse the ‘Preface’s of contemporary Histology books, qualitatively, for noting the approaches taken and means applied in presenting Cell Biology and Histology in the books. Methods: The study was descriptive, observational and qualitative in nature, carried out in the Department of Anatomy, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, between July 2007 and June 2008. The study materials were the ‘Preface’s of fifteen Histology books dealing with Cell Biology and Histology, published since 1984. The ‘Preface’s were analysed qualitatively to identify the information provided and comments made by their authors/editors on the approaches taken and means applied in the books in selecting and presenting topics, text and illustrations. The observations were organised into specific ‘theme’s. Results: Sixteen ‘theme’s could be identified. These include, among others, special emphasis in the books on following curricular reforms, incorporation of new information and special focus on the relationship of structures with functions. Additions and improvements regarding tables and illustrations are also highlighted. Conclusion: By incorporating the findings of the present study with the present-day ideas and trends in Cell Biology and Histology teaching-learning and assessment in the renowned institutions of the world, as evident from the available literature, suggestions can be formulated on improving the methods of teaching and assessment in Cell Biology and Histology in Bangladesh.DOI: http://dx.doi.org/10.3329/bsmmuj.v5i1.11017 BSMMU J 2012; 5(1):46-54

The alterations in the vascularization of the developing palate were studied through the use of resin cast images of vascular networks in normal and spontaneous cleft lip and palate (CL/Fr) mouse embryos (crown rump [CR] Length 9-18 mm, body wt. 0.11-0.65 g). A more dense vascular plexus was observed in the oral side than in the nasal side before the reorientation of the palatal shelves. Prominent terminal dilatations of the vascular plexus were observed in the extreme medial edge of the elevating palatal shelves which may exert significant force for palatal shelf elevation. The vascular plexus showed a lateral extension. Many small spherical masses of resin were observed in the medial edge of the palatal shelves at the time of medial extension and during fusion, indicating some changes occurring in the capillary wall leading to the resin leakage. In the spontaneous cleft group, a similar vascular pattern was observed, but the greater palatine artery showed discontinuity in the premaxillary region at an early stage. At the same time, terminal dilatations were delayed and frequently absent in the contralateral shelf. After the reorientation of the palatal shelves, the vascular plexus formed an irregular lattice pattern. Dilated vasculature was apparent in the anterior nasopalatine region, indicating the persistence of a more primitive vascular structure in the spontaneous cleft embryos. However, the area where capillary dilatation occurred was different between unilateral and bilateral cleft embryos. In conclusion, blood vessels in the palatal shelves are underdeveloped and remained immature in cleft lip and palate embryos and showed different patterns in the anterior nasopalatine region between unilateral and bilateral cleft embryos. These variant vascular patterns may be due to the inadequate blood supply to the nasopalatine region from the early embryonic stages possibly resulting from the discontinuity of the greater palatine artery.
