摘要
背景。人们早就知道,宏观生物和微生物的重要活动都需要叶酸。它是甲基化、核苷酸合成、蛋氨酸形成和降低同型半胱氨酸毒性作用所必需的。在孕妇的饮食中以及在孕前准备阶段添加合成叶酸,可以显著降低胎儿神经管缺陷、心脏缺陷以及可能的其他身体器官和系统的风险。此外,叶酸可以帮助提高生育潜力。然而,有证据表明,叶酸对老年人(隐藏b12缺乏状态)和服用医学专家规定的高剂量叶酸的母亲的后代的健康产生不利影响,如儿童感染-炎症和上呼吸道过敏疾病、湿疹、精神运动发育障碍和胰岛素抵抗的风险。1980年证实了叶酸对中枢神经系统突触传递的直接兴奋作用。这是由于分子结构,它含有l -谷氨酸。因此,这项工作的目的是试图证明现有的可能神经病理学的相关数据,包括癫痫发作阈值降低,在Wistar大鼠的后代模型中增加叶酸剂量,在整个妊娠期间,包括在妊娠前准备阶段,癫痫的高风险。方法。我们通过以每公斤体重100毫克的速率将20%的咖啡因溶液注入腹腔,确定了首次抽搐行为的能力。结果。对照组平均克隆时间为1779.6 s,试验组每日粮添加1 mg/kg叶酸的克隆时间为797.3 s,试验组每日粮添加5 mg/kg叶酸的克隆时间为439.7 s (p < 0.01)。结论。所获得的惊厥阈值差异的结果可能是由于突触密度的变化,这是由于在NT形成期间以及随后在中枢神经系统神经组织分化期间(特别是在妊娠晚期大量出现谷氨酸能受体)合成叶酸过量所导致的,这可以影响神经发生过程和神经网络的形成。
Effect of synthetic folic acid surplus on neurological symptoms in offspring
Background. It has long been known about the need for folic acid for the vital activity of both macro-and microorganisms. It is necessary for the processes of methylation, nucleotide synthesis and also the formation of methionine and reducing the toxic effect of homocysteine. The addition of synthetic folic acid to the diet of pregnant women, as well as at the stage of pre-pregnancy preparation, significantly reduces the risks of fetal neural tube defects, heart defects, and possibly other organs and systems of the body. In addition, folic acid can help improve fertility potential. However, there is evidence of adverse effects of folic acid proficite on the health of older adults (hiding B12-deficient status) and the offspring of mothers taking high doses prescribed by medical specialists like a risks of infectious-inflammatory and allergic diseases of the upper respiratory tract in children, eczema, also disorders of psychomotor development and insulin resistance. In 1980, the direct excitatory effect of folic acid on synaptic transmission in the central nervous system was proved. This is due to the molecular structure, it contains L-glutamate.
Therefore, the aim of the work was trying to prove the existing correlation data on probable neuropathologies, including a reduced threshold of seizures, a high risk of epilepsy in a model of offspring of Wistar rats with an increased dosage of folate throughout gestation and including at the stage of pre-gravidar preparation.
Methods. We have determined the ability to the first convulsive act by introducing a 20% solution of caffeine at the rate of 100 mg/kg of weight intraperitoneally.
Results. In the control group, the average clonus time was 1779.6 seconds, in the experimental group with a 1 mg/kg folic acid per diet dosage of 797.3 seconds, and in the second group with a 5 mg/kg folic acid per diet 439.7 seconds (p 0,01).
Conclusion. The obtained results of the difference in the convulsive threshold may be due to changes in synaptic density as a result of an excess of synthetic folic acid during the formation of NT and subsequently during the differentiation of nervous tissue in the central nervous system (in particular, in the 3rd trimester with a massive appearance of glutamatergic receptors), which can affect the processes of neurogenesis and the formation of neural networks.
