1981年和1982年，在阿拉斯加山脉和北极国家野生动物保护区捕获了85只灰熊（Ursus arctos）。从这些熊的血清，沿着从76熊的血清捕获之间的1973年和1980年在布鲁克斯范围，阿拉斯加，进行了检查的24个血清特征。泌乳母猪的高钙和磷需求导致血清水平低于非泌乳母猪。男性有较高的钙和P值比所有女性。升高水平的P，碱性磷酸酶，谷氨酰-谷氨酸和谷氨酰-谷氨酸转氨酶，尿素氮，肌酐，尿酸在第一次相比，第二次样品，收集1小时后，可能与兴奋性和体力消耗强加给熊的捕获。第二个样本中较高水平的氯化物和二氧化碳表明对处理压力引起的过度换气的反应。捕获日期的差异可能解释了尿素氮、肌酐和尿酸的地理差异，这表明随着从den出现时间的增加，肾功能恢复和不同的饮食恢复。钙、磷和碱性磷酸酶与年龄的负相关性反映了幼熊成骨细胞活性和骨形成的增加。这些结果增加了熊血清特征的基线，确定了对它们的影响，允许与其他地理区域的种群进行比较，并表明在捕获和处理熊时应小心，以尽量减少生理压力。
Eighty-five grizzly bears (Ursus arctos) were captured during 1981 and 1982 in the Alaska Range and Arctic National Wildlife Refuge, Alaska. Blood serum from these bears, along with serum from 76 bears captured between 1973 and 1980 in the Brooks Range, Alaska, was examined for 24 serum characteristics. A high Ca and P demand in lactating sows resulted in lower serum levels than in nonlactating sows. Males had higher Ca and P values than all females. Elevated levels of P, alkaline phosphatase, glutamic-oxalacetic and glutamic-pyruvic transaminases, urea nitrogen, creatinine, and uric acid in first compared to second samples, collected 1 hour later, are probably related to excitability and physical exertion imposed on bears by their capture. Higher levels of chloride and carbon dioxide in second samples indicate a response to hyperventilation caused by handling stress. Differences in capture dates probably account for geographic differences in urea nitrogen, creatinine, and uric acid, suggesting regained renal function and varied diet reinstatement as time from den emergence increases. Negative correlations of Ca, P, and alkaline phosphatase with age reflect increased osteoblast activity and bone formation in young bears. The results add to the baseline on bear serum characterictics, identify influences on them, allow for comparisons with populations in other geographic areas, and indicate care should be taken during capture and handling of bears to minimize physiological stress.
