PBS高端访谈:加利福尼亚兽医用生物绷带治愈烧伤棕熊（在线收听）

JUDY WOODRUFF: Now to our NewsHour Shares. When two black bears were burned in a California wildfire, veterinarians used a treatment never tried before on animals. Our Julia Griffin explains.

JULIA GRIFFIN: December's Thomas Fire was the largest on record in California, scorching more than 280,000 acres and destroying more than 1,000 homes. But while most human residents could escape the inferno, two black bears rescued by the California Department of Fish and Wildlife weren't so lucky.

Trapped by the flames, they had suffered severe second- and third-degree burns to their paws.

DR.JAMIE PEYTON, U.C. Davis veterinarian: This is all that is left of her normal pad.

JULIA GRIFFIN: For U.C. Davis veterinarian Jamie Peyton, addressing the bears' injuries would require outside-the-box thinking, namely, treating the burns with tilapia skins.

DR.JAMIE PEYTON: The bear, I will tell you, is probably the one that really inspired me to look into the tilapia bandages, because her wounds were so extensive and her pain was so severe. She was the one that made me say, you know, I need to do something else.

What else can I do?

JULIA GRIFFIN: Peyton knew doctors in Brazil had seen success in treating human burn victims with sterilized tilapia skin and was keen to try it on her animal patients.

DR.JAMIE PEYTON: If you look at the literature, treating wild animals that have experienced this degree of burns just hasn't been done.

JULIA GRIFFIN: The collagen in tilapia skin acts like a biological bandage, protecting and moisturizing the skin while promoting healing. And in this instance, Peyton wrapped the sutured wounds with corn husks to delay her patients' attempts to eat their edible dressings. Positive results were almost immediate.

DR.JAMIE PEYTON: Nothing is more rewarding than when you take an animal that won't walk because she's so painful. And we try a new therapy, and put those bandages, the tilapia skin, on her feet, and right after we got done, and she woke up, she stood up for the first time and was able to walk.

JULIA GRIFFIN: A speedy recovery was crucial. Limiting the bears' time in captivity would greatly improve their chances of long-term survival, especially since one was pregnant and would be better off delivering in the wild. So, while Peyton oversaw the bears' final treatment, Fish and Wildlife officials set in motion plans to release them, building two manmade, bear-approved dens five miles apart in unburned parts of Los Padres National Forest.

WOMAN: Bye, sweetheart. You are a good girl.

JULIA GRIFFIN: Sedated and secured, all that was left to do was deliver the bears to their new homes. Her patients discharged, Peyton reflected on the success of her unique treatment plan.

DR.JAMIE PEYTON: The tilapia skin, in my opinion is, one of those things that, you know, people said to me, what? That doesn't makes sense. You can't do that. And when someone says, you can't, I always think to myself, oh, I will. And I will make it happen, because I'm just passionate about these animals and about helping

them and allowing them to heal.

朱蒂·伍德瑞夫：现在到了我们的《NewsHour Shares》栏目时段。当两只黑熊遭遇加利福尼亚野火，被烧伤时，兽医们使用了从未在动物身上使用过的治疗手段。我们的朱丽亚·格里芬为我们讲述。

朱丽亚·格里芬：十二月份的Thomas Fire是加利福尼亚有史以来最大的一次，它烧毁了超过280,000英亩的土地，以及1000多所房屋。虽然大多数人类居民都已安全撤离，但获得California Department of Fish and Wildlife营救的两只黑熊却没那么幸运。由于身陷火中，他们的爪子受到了严重的二度及三度烧伤。

杰米·佩顿医生，加州大学戴维斯分校兽医：她正常的掌垫，就剩下这点了。

朱丽亚·格里芬：对于加州大学戴维斯分校的兽医杰米·佩顿来说，要治愈熊的伤，就要跳出固有的思维模式，即用罗非鱼皮治疗烧伤。

杰米·佩顿医生：这只熊，我会告诉你，很可能真正激发我去深入研究罗非鱼绷带，因为她的伤口分布非常广泛，伴随剧烈疼痛。她让我认为，你知道，我需要做点其他事情。我还能做什么？

朱丽亚·格里芬：佩顿知道巴西的医生曾用消过毒的罗非鱼皮成功治愈了烧伤患者，她很想在她的动物患者们身上试一试。

杰米·佩顿医生：如果你查看文献记录，治疗如此烧伤程度的野生动物尚属首例。

朱丽亚·格里芬：罗非鱼皮肤中的胶原蛋白就像生物绷带一样，可以保护和滋润皮肤，促进伤口愈合。在这种情况下，佩顿把缝合的伤口用玉米外皮包裹起来，好让她的病人不要去吃他们的食用敷料。好的效果几乎立即就出现。

杰米·佩顿医生：让因痛苦无法行走的动物站立起来是最有成就感的事情了。我们尝试一种新疗法，把绷带，即罗非鱼皮肤，裹在她的脚上，我们刚做完，她就醒了，她第一次站了起来，能走路了。

朱丽亚·格里芬：迅速恢复至关重要。尽量控制熊的伤愈时间，将大大提高它们长期存活的机率，特别是自从怀孕后，在野外分娩就好多了。所以，当佩顿负责熊的最终治疗处理时，Fish and Wildlife的官员们开始为放生制定计划，在帕德里斯国家森林公园为经野火燃烧的地方，建造两个人造，熊喜欢的窝洞，这两个窝洞相距五英里。

女人：再见，甜心。你是个好女孩。

朱丽亚·格里芬：平静而又安全，只剩下把熊送到它们新的家园了。她的病人们出院了，佩顿认真考虑了她独特而又成功的治疗计划。

杰米·佩顿医生：在我看来，你知道，罗非鱼的皮肤只是人们对我说“什么？那没有道理。你不能那样做。”的材料中的一个。当有人说，你不能，我总是对自己说，哦，我能。并且我会让它成为现实，因为对这些动物，以及帮助他们痊愈，我充满热情。
