【摘要】：有關(guān)年齡對(duì)哺乳動(dòng)物血液和線粒體功能指標(biāo)的影響研究非常有限,本項(xiàng)目以豬為模型,重點(diǎn)研究年齡對(duì)巴馬香豬公豬血液和線粒體功能指標(biāo)的影響。選用1歲、4歲和9歲公豬各2頭、3頭和3頭進(jìn)行屠宰,稱量各器官質(zhì)量,并采集血樣和組織樣品分析其生理、生化、免疫、激素和線粒體功能共58項(xiàng)指標(biāo)的變異。結(jié)果表明,除體質(zhì)量隨年齡的增長而增大外,9歲公豬與4歲公豬腎臟的絕對(duì)質(zhì)量也有顯著性差異(P0.05)。4歲巴馬香豬公豬的WBC、GR、RBC和HCT顯著高于9歲公豬(P0.05);隨著年齡的增長,WID%、PCT、TG、AST和ALT呈下降趨勢(shì),而GR%、MCV、MCH、RDW-SD、RDW-CV、PDW、HDL、R-GT、UA和TP呈上升趨勢(shì)。1歲公豬的GH和T平均水平要遠(yuǎn)高于其他兩個(gè)年齡段公豬,而4歲和9歲公豬這兩指標(biāo)水平相當(dāng),說明這兩指標(biāo)的水平隨著年齡的增長而下降,到一定年齡后維持在一穩(wěn)定的水平;INS的水平隨著年齡的增長先升后降。9歲巴馬香豬公豬肝臟的最大呼吸能力、呼吸儲(chǔ)備以及肌肉的呼吸儲(chǔ)備高于1歲公豬,可能與9歲公豬體質(zhì)量及身體代謝水平遠(yuǎn)高于1歲公豬有關(guān);肌肉的ATP生成低于1歲公豬,說明隨著年齡的增長,肌肉出現(xiàn)老化,從而導(dǎo)致ATP生成的降低。肌肉的基礎(chǔ)呼吸率和ATP生成高于肝臟,而呼吸儲(chǔ)備卻更低,這與兩個(gè)器官的功能差異相關(guān)。
[Abstract]:Studies on the effects of age on mammalian blood and mitochondrial function were limited. The effect of age on blood and mitochondria function of Bama boar was studied. Two male pigs aged 1 year old 4 years old and nine year old boars were slaughtered to weigh the weight of each organ and to collect blood samples and tissue samples to analyze their physiology. Variations in 58 biochemical, immunological, hormonal and mitochondrial functions. In addition to the increase of body weight with age, there was also significant difference in the absolute weight of kidney between 9 year old boar and 4 year old boar. The RBC and HCT of Bama Xiang pig at 4 years old were significantly higher than that of 9 year old boar (P 0.05). The mean levels of GH and T of the 1-year-old boars were much higher than those of the other two age boars, but the two indexes of 4 and 9 year old boars were similar, which indicated that the levels of these two indexes decreased with the increase of age, and the mean levels of GH and T in the 1st year old boars were much higher than those in the other two age groups, while the RDW-SDN RDW-SDN RDW-CVU PDWN HDLR-GTU UA and TP showed an increasing trend. After a certain age, the level of ins was maintained at a stable level. With the increase of age, the level of ins rose first, then decreased with age. The maximum respiratory capacity, respiratory reserve and muscle respiratory reserve in the liver of 9 year old Bama boars were higher than that of 1 year old boars. It may be related to the body weight and metabolic level of 9-year-old boar, and the ATP production of muscle is lower than 1-year-old boar, which indicates that the muscle is aging with age. The basic respiratory rate and ATP production of muscle are higher than that of liver, but the respiratory reserve is lower, which is related to the difference of function between the two organs.
