前列腺素(PG_s)与眼病的关系,特别是与眼部炎症的明显关系已为大家所熟知。如葡萄膜炎时,房水中PG_s含量升高,在兔眼中PG_s可引起结膜充血、瞳孔缩小、房水蛋白含量增加等。眼的许多部位能合成PG_s,而结膜中PG_s的前体物质含量最高。但炎症时泪液中PG_s含量的研究报道少见。作者测定了25例白内障囊内摘出术后炎症反应时泪液中前列腺素E_2(PGE_2)的含量,以进一步阐明人眼炎症时PGE_2的作用。 25例患者除患白内障外,身体健康。年龄:35～93岁,平均70岁。均作结膜瓣,囊内摘出白内障。所有患者均在术前一天、术后1～6天以
The relationship between prostaglandin (PG_s) and ophthalmopathy, particularly the apparent relationship with ocular inflammation, is well known. Such as uveitis, aqueous humor PG_s content increased in the rabbit eye PG_s can cause conjunctival hyperemia, miosis, aqueous humor protein content increased. PG_s can be synthesized in many parts of the eye, while PG_s has the highest content of precursors in the conjunctiva. However, the study of PG_s in the tear in inflammation is rare. The authors measured the contents of prostaglandin E_2 (PGE_2) in tears after cataract extraction from cataract in order to clarify the role of PGE_2 in human eye inflammation. In addition to cataract, 25 patients were in good health. Age: 35 ~ 93 years old, average 70 years old. All conjunctival flap, cataract extraction within the capsule. All patients were in the preoperative day, 1 to 6 days after surgery
