Annual health records were retrospectively analyzed for a colony of ring-tailed lemurs () inhabiting St. Catherines Island, Georgia, USA to establish baseline hematological and serum biochemical parameters and determine sex- and age-related differences. Summarized complete blood count and serum biochemistry panel results are presented for 85 blood samples collected from 54 lemurs at annual health exams during 1998-2003. Within each of four age classes (infant, <1 yr; juvenile, 1-5 yr; adult, ≥ 6 yr), data were stratified and summarized based on sex. Lemur age was a significant positive predictor of mean corpuscular hemoglobin; absolute concentrations of neutrophils, monocytes, and band cells; serum concentrations of blood urea nitrogen (BUN), creatinine, globulins, lipase, and total protein; and gamma-glutamyl transferase (GGT) activity. Lemur age was a significant negative predictor of albumin:globulins ratio; alkaline phosphatase (ALP) activity; and serum concentrations of calcium, cholesterol, glucose, magnesium, phosphorus, potassium, and triglycerides. Neutrophil proportions increased with aging and lymphocyte proportions decreased with aging, particularly in females. Recent steep population declines of wild ring-tailed lemurs make their successful husbandry and medical care an increasingly pressing concern. These biomedical data will aid in clinical diagnosis and treatment of lemurs in human care, and support conservation efforts for this species.
对美国佐治亚州圣凯瑟琳斯岛的一个环尾狐猴种群进行了年度健康记录的回顾性分析，以确定其血液学和血清生化参数的基线值，并确定性别和年龄相关的差异。本文总结了 1998 年至 2003 年期间，对在年度健康检查中采集的 85 份血液样本的完整血细胞计数和血清生化小组检测结果，这些样本来自 54 只环尾狐猴。在四个年龄组（婴儿期，<1 岁；幼年期，1-5 岁；成年期，≥6 岁）内，基于性别对数据进行分层和总结。狐猴的年龄与平均红细胞血红蛋白、中性粒细胞、单核细胞和带状细胞的绝对浓度、血清尿素氮（BUN）、肌酐、球蛋白、脂肪酶和总蛋白浓度以及γ-谷氨酰转移酶（GGT）活性呈显著正相关。狐猴的年龄与白蛋白/球蛋白比值、碱性磷酸酶（ALP）活性以及血清钙、胆固醇、葡萄糖、镁、磷、钾和甘油三酯浓度呈显著负相关。中性粒细胞比例随年龄增长而增加，淋巴细胞比例随年龄增长而减少，尤其是在雌性中。野生环尾狐猴的数量最近急剧下降，使得对它们的成功饲养和医疗护理成为一个日益紧迫的问题。这些生物医学数据将有助于在人类护理中对狐猴进行临床诊断和治疗，并支持该物种的保护工作。
