An argon ion laser beam was tested experimentally with regard to its histological effect on and penetration of the gastric mucosa of the rat and man and its ability to induce haemostasis in traumatically produced gastric lesions and transected small blood vessels. Localized laser photocoagulation for periods of up to 5 minutes at 1 watt produced a coagulative necrosis of the gastric mucosa and half of the muscularis propria, but transmural necrosis required prolonged exposure. Laser phototherapy markedly reduced the bleeding time in experimental ulcers and small blood vessels, provided the superficial blood could be adequately dispersed from the direct beam of the laser.
对氩离子激光束进行了实验测试，观察其对大鼠和人类胃黏膜的组织学影响、穿透能力，以及在创伤性胃损伤和横断小血管中诱导止血的能力。在1瓦功率下进行长达5分钟的局部激光光凝，可导致胃黏膜和一半固有肌层发生凝固性坏死，但全层坏死需要长时间照射。激光光疗显著缩短了实验性溃疡和小血管的出血时间，前提是浅表血液能够充分从激光直射光束中散开。
