问题 单项选择题

用药期间可引起眼泪、尿、粪、痰等成橘红色的药物是()

A.吡嗪酰胺

B.异烟肼

C.链霉素

D.利福平

E.乙胺丁醇

答案

参考答案:D

解析:

本题考查抗结核药的典型不良反应。吡嗪酰胺可导致血尿酸升高。异烟肼适用于各种类型结核病,主要不良反应为神经系统的周围神经炎,此外还有肝毒性、胃肠道反应、皮疹和溶血性贫血等。利福平与他药合用治疗各种结核病,尤其是泌尿系结核伴肾功能不全者。

不良反应为胃肠道反应、肝毒性和流感综合征;利福平药物及其代谢产物均为橘红色,故用药期间可引起眼泪、尿、粪、痰等成橘红色。乙胺丁醇与其他抗结核病药合用治疗各型肺结核和肺外结核,可为异烟肼、链霉素耐药的替换药,连续大量使用可引起球后神经炎,出现弱视、红绿色盲和视野缩小。

     Short and shy, Ben Saunders was the last kid in his class picked for any sports team. "Football, tennis, cricket-anything with a round ball. I was useless," he says now with a laugh. But back then he was the

object of jokes in school gym classes in England's rural Devonshire.

     It was a mountain bike he received for his 15th birthday that changed him. At first the teen went biking alone in a nearby forest, then he began to cycle along with a runner friend. Gradually, Saunders set his

mind on building up his body, increasing his speed, strength and endurance. At age 18, he ran his first

marathon.

     The following year, he met John Ridgway, who became famous in the 1960s for rowing an open boat

across the Atlantic Ocean. Saunders was hired as an instructor at Ridgway's School of Adventure in

Scotland, where he learned about the old man's cold-water exploits(成就). Intrigued, Saunders read all

he could about Arctic explorers and North Pole expeditions, then decided that this would be his future.

     Journeys to the Pole aren't the usual holidays for British country boys, and many people dismissed his

dream as fantasy. "John Ridgway was one of the few who didn't say 'You're completely crazy," Saunders

says.

     In 2001, after becoming a skilled skier, Saunders started his first long-distance expedition toward the

North Pole. He suffered frostbite, had a close encounter with a polar bear and pushed his body to the limit.

     Saunders has since become the youngest person to ski alone to the North Pole, and he's skied more of the Arctic by himself than any other Briton. His old playmates would not believe the transformation.

     This October, Saunders, 27, heads south to explore from the coast of Antarctica to the South Pole and back, a 1,800-mile journey that has never been completed on skis.
