Hypogalactia and agalactia in lactating mothers are the major causes of child malnutrition, mortality, morbidity, and overall ill health. The development of such treatments requires a well-designed preclinical study with suitable laboratory animals, which needs to be improved. Thus, a suitably designed study with a laboratory animal to analyse galactagogue activity, along with an assessment of the quality and quantity of milk, is required.
This study aimed to evaluate the potential of rabbit as an animal model for studying lactogenic activity.
The structural homology of prolactin, gene prolactin receptor, and prolactin hormone in humans, rabbit, and rat was studied using BLAST and PyMol to assess similarity in the lactogenic system. Daily and cumulative milk production and pre-treatment (control) and post-treatment (three drugs) in rabbits were recorded and evaluated by analysing protein, fat, lactose, solid non-- fat, and ash values. All parameters were recorded on the 0th day and at the end of weeks 1, 2, and 3. Mammary gland histopathology was performed to evaluate the effects on mammary glands.
Homology studies revealed that the sequences of the human and rabbit prolactin genes, receptors, and hormones had a high similarity index. Treatment with Domperidone, Metoclopramide, and Shatavari significantly enhanced milk production by enhancing prolactin secretion; only Shatavari increased milk nutrition. Enlargement of the tubuloalveolar ducts of the mammary glands was observed.
Our findings suggest that rabbits are robust, reproducible, ethically superior, and preclinically relevant animals for assessing lactogenic activity.
哺乳期母亲的乳汁分泌不足和无乳是儿童营养不良、死亡、发病及整体健康状况不佳的主要原因。此类治疗方法的开发需要在合适的实验动物身上进行精心设计的临床前研究,而这方面仍有待改进。因此,需要设计一项合适的研究,利用实验动物分析催乳活性,并评估乳汁的质量和数量。
本研究旨在评估兔子作为研究催乳活性动物模型的潜力。
使用BLAST和PyMol研究人类、兔子和大鼠中催乳素、催乳素基因受体及催乳素激素的结构同源性,以评估催乳系统的相似性。记录并分析兔子的每日和累计产奶量以及预处理(对照)和后处理(三种药物)情况,通过分析蛋白质、脂肪、乳糖、非脂固形物和灰分的值进行评估。所有参数均在第0天以及第1、2、3周结束时记录。进行乳腺组织病理学检查以评估对乳腺的影响。
同源性研究表明,人类和兔子的催乳素基因、受体及激素序列具有较高的相似性指数。多潘立酮、甲氧氯普胺和沙塔瓦里治疗通过增强催乳素分泌显著提高了产奶量;只有沙塔瓦里增加了乳汁营养。观察到乳腺的小管泡状导管增大。
我们的研究结果表明,兔子是用于评估催乳活性的健壮、可重复、符合伦理且具有临床前相关性的动物。
