目的 观察恒河猴感染间日型猴疟后原虫密度消长与PLT数值的关系及抗菌药物和抗疟药治疗后对PLT变化的影响.方法 健康猴1只,经血液感染间日型猴疟后2 d开始采血检查疟原虫及PLT计数.发现疟原虫后24 d,阿奇霉素治疗3 d,总量为1500 mg;发现疟原虫后30 d,青蒿琥酯治疗5 d,总量为194.4 mg.观察治疗期间疟原虫与PLT变化规律.同时设健康对照猴1只.结果 实验猴被感染疟原虫前PLT计数为240×109/L,感染后,当血疟原虫为2/100 WBC时,PLT计数为540×109/L.感染猴原虫密度波动在(1~60)/100 WBC,而PLT数值维持在(130~150)×109/L之间.实验猴灌服阿奇霉素后,原虫密度波动在(16~64)/100 WBC之间,而平均PLT计数回升到234.5×109/L,接受青蒿琥酯治疗64 h后血检未发现原虫,PLT计数平均值已回升到247×109/L.结论 疟原虫感染后PLT计数下降,阿奇霉素和青蒿琥酯治疗猴疟能较快提升PLT计数.
目的 觀察恆河猴感染間日型猴瘧後原蟲密度消長與PLT數值的關繫及抗菌藥物和抗瘧藥治療後對PLT變化的影響.方法 健康猴1隻,經血液感染間日型猴瘧後2 d開始採血檢查瘧原蟲及PLT計數.髮現瘧原蟲後24 d,阿奇黴素治療3 d,總量為1500 mg;髮現瘧原蟲後30 d,青蒿琥酯治療5 d,總量為194.4 mg.觀察治療期間瘧原蟲與PLT變化規律.同時設健康對照猴1隻.結果 實驗猴被感染瘧原蟲前PLT計數為240×109/L,感染後,噹血瘧原蟲為2/100 WBC時,PLT計數為540×109/L.感染猴原蟲密度波動在(1~60)/100 WBC,而PLT數值維持在(130~150)×109/L之間.實驗猴灌服阿奇黴素後,原蟲密度波動在(16~64)/100 WBC之間,而平均PLT計數迴升到234.5×109/L,接受青蒿琥酯治療64 h後血檢未髮現原蟲,PLT計數平均值已迴升到247×109/L.結論 瘧原蟲感染後PLT計數下降,阿奇黴素和青蒿琥酯治療猴瘧能較快提升PLT計數.

Objective To observe platelet dynamics in a monkey infected with Plasmodium cynomolgi before and after treatments with antibiotics and antimalarial drug. Methods One experimental monkey was examined for parasite density and platelet count 2 days after parasite inoculation. Observation without treatment continued for 24 days after the parasite was detected in the blood sample of the monkey. Then the monkey was treated with Azithromycin (total 1500 mg) for 3 days. Thirty days after parasite detection in the blood, the monkey was treated with Artesunate for 5 days. Parasite density and platelet count were monitored daily during treatments. The result was compared with that from a healthy monkey as control. Results The experimental monkey's platelet count was 240× 109/L before infection. When parasite density was 2/100 white blood cells (WBC),platelet count increased to 540 × 109/L. During the subsequent period of infection, parasite density fluctuated at (1-60)/100 WBC, and the platelet count reduced to a persistent level of (130-150)×109/L. After the infected monkey was treated with Azithromycin, parasite density reduced initially but subsequently fluctuated at (16-64)/100 WBC. Meanwhile, platelet count was restored to 234.5 × 109/L.The infected monkey was treated with Artesunate and parasite clearance time was 64 hours, and the mean platelet count was 247 × 109/L after treatment. Conclusion Azithromycin and Artesunate treatment have direct influence on the recovery of platelet counts during malaria infection in monkeys.
