Abstract

Context: The pineal gland is capable of influencing or modifying the activity of the pituitary gland, islets of Langerhans, the parathyroid gland, adrenal gland and the gonads. The pineal gland through its hormone, melatonin influences many functions of the human, like circadian rhythm, mood, psychiatric disorder, sexual maturation, reproduction and aging. Melatonin, a potent antioxidant provides protection against damaging free radicals of oxygen. Various clinical problems occur due to abnormal melatonin secretion by the pineal gland. For the perfect and complete evaluation of various clinical conditions of the pineal gland, detailed morphological knowledge is essential. Study Design: Cross sectional analytical type of study. Place and period of study: Department of Anatomy, Dhaka Medical College, Dhaka from July 2009 to June 2010. Materials: 60 postmortem human pineal glands were collected from unclaimed dead bodies that were under examination in the morgue of the Department of Forensic Medicine, Dhaka Medical College Dhaka. Methods: The samples were divided into four different age groups i.e. Group-A (15-30 years), Group-B (31- 40 years), Group-C (41-50 years) and Group-D (> 50 years). Results: The mean±SD length of the pineal gland were found 8.11±0.83 mm in group A, 7.96±1.06 mm in group B, 7.51±0.55 mm in group C and 7.89±0.14 mm in group D. The mean±SD breadth of the pineal gland were found 4.39±0.34 mm in group A, 4.09±0.46 mm in group B, 4.12±0.58 mm in group C and 3.81±0.34 mm in group D. The mean±SD thickness of the pineal gland were found 2.52±0.64 mm in group A, 2.29±0.54 mm in group B, 2.14±0.32 mm in group C and 2.07±0.18 mm in group D. Conclusion: breadth and thickness of the pineal gland were found to be decreased with advancing age.

松果体的长度、宽度和厚度

背景:松果体能够影响或改变脑垂体、朗格汉斯岛、甲状旁腺、肾上腺和性腺的活性。松果体通过其分泌的褪黑激素影响人体的许多功能，如昼夜节律、情绪、精神障碍、性成熟、生殖和衰老。褪黑素是一种有效的抗氧化剂，可以防止有害的氧自由基。松果体分泌褪黑激素异常可引起各种临床问题。为了完善和完整地评价松果体的各种临床状况，详细的形态学知识是必不可少的。研究设计:横断面分析型研究。学习地点和时间:2009年7月至2010年6月，达卡医学院解剖学系。材料:在达卡医学院法医系太平间检查的无人认领的尸体上收集了60具死后人体松果体。方法:将样本分为a组(15 ~ 30岁)、b组(31 ~ 40岁)、c组(41 ~ 50岁)和d组(50 ~ 50岁)4组。结果:均值±SD松果体的长度被发现在A组8.11±0.83毫米,7.96±1.06毫米在B组、C组7.51±0.55毫米和7.89±0.14毫米在d组均值±SD的松果体被发现在A组4.39±0.34毫米,4.09±0.46毫米在B组、C组4.12±0.58毫米和3.81±0.34毫米在d组均值±SD松果体被发现厚度2.52±0.64毫米在A组,B组2.29±0.54毫米,2.14±0.32毫米在C组和2.07±0.18毫米在d组,结论:松果体的宽度和厚度随着年龄的增长而减小。DOI: http://dx.doi.org/10.3329/bja.v10i2.17286孟加拉解剖学杂志，2012年7月，Vol. 10 No. 2 pp 63-67
