Aging, a multifactorial process of enormous complexity is characterised by physio-chemical and biological aspects of cellular functions. It is closely associated with changes in metabolism of various biological molecules in the system. In the present study, we have investigated the effect of deprenyl on cerebellum during ageing process in male Wistar rats with respect to the changes in levels of protein, glycoproteins and amino acids in experimental rats of three age groups (6, 12 and 18 months old). Intraperitoneal administration of liquid deprenyl (2 mg/kg body weight/day for a period of 15 days i.p., significantly P < 0.05) attenuated age-associated alterations in the levels of amino acids (taurine, aspartate, glutamate, arginine, hydroxy proline and homocysteine), protein content and glycoprotein components (hexose and hexosamine) in the rat cerebellum. The results of the present investigation indicate that the protective effect of deprenyl is probably related to its ability to strengthen the neuronal membrane by its membrane stabilizing action or to a counteraction of free radicals by its antioxidant property.
衰老是一个极其复杂的多因素过程,其特征是细胞功能的生理化学和生物学方面。它与系统中各种生物分子代谢的变化密切相关。在本研究中,我们研究了去甲替林对雄性 Wistar 大鼠小脑在衰老过程中的影响,研究了三个年龄组(6、12 和 18 个月大)实验大鼠中蛋白质、糖蛋白和氨基酸水平的变化。腹腔内给予液体去甲替林(2mg/kg 体重/天,腹腔内给药 15 天),显著 P<0.05)减轻了与年龄相关的氨基酸(牛磺酸、天冬氨酸、谷氨酸、精氨酸、羟脯氨酸和高半胱氨酸)、蛋白质含量和糖蛋白成分(己糖和己糖胺)水平的变化。本研究的结果表明,去甲替林的保护作用可能与其通过膜稳定作用增强神经元膜的能力有关,或者与其通过抗氧化作用对抗自由基的能力有关。
