葛根素对急性胰腺炎患者血浆内皮素和一氧化氮的影响

目的 研究急性胰腺炎(AP)时血浆内皮素(ET)、一氧化氮(NO)变化和葛根素对其影响,并探讨葛根素对AP的治疗作用.方法 AP患者73例,采用随机数字表法分为葛根素治疗组38例及非葛根素治疗组35例.葛根素治疗组用基础治疗+葛根素;非葛根素治疗组除未用葛根素外治疗方法与葛根素治疗组相同.两组治疗前后均应用放射免疫法测定血浆ET,用硝酸还原酶法测定NO,血、尿淀粉酶用Somogyi法,同时以健康体检者20例作为对照组.结果 葛根素治疗组治疗后血浆ET[(40.6±15.8)ng/L]、NO[(62.3±27.6)mmol/L]明显下降,与非葛根素治疗组[(82.3±20.6)ng/L、(92.6±24.8)mmol/L]比较差异有统计学意义(P<0.05).血、尿淀粉酶[(802.0±170.0)、(4102.0±1126.0)U/L]、腹痛缓解时间[(2.20±0.72)d]与非葛根素治疗组[(1182.0±520.0)、(5623.O±1326.0)U/L和(5.12±0.76)d]比较差异有统计学意义(P<0.05).结论 血浆ET、NO异常变化可能是AP发生、发展的主要因素之一.葛根素可改善胰腺微循环和拮抗ET、NO,对AP有一定治疗作用.

Influence of puerarin treatment on endothelin and nitric oxide of plasma in patients with acute pancreatitis

Objective To study changes of endothelin (ET),nitric oxide (NO) in plasma and treatment effect of puerarin on acute pancreatitis (AP). Methods Seventy-three patients with AP were randomly divided into 2 groups: puerarin group (38 cases, puerarin plus basic treatment) and non puerarin group (35 cases, basic treatment ). ET was measured by radioimmunoassay, NO was measured by nitrate reductase and plasma amylase and uric amylase were determined by Somogyi before and after the treatment.Twenty healthy persons were recruited as control group. Results The levels of ET[(40.6±15.8) ng/L]and NO[(62.3±27.6) mmol/L] decreased after treatment in puerarin group, which were significantly lower than those in non puerarin group[(82.3±20.6) ng/L, (92.6±24.8 ) mmol/L]( P < 0.05 ). Compared with those in non puerarin group[(1182.0±520.0), (5623.0±1326.0) U/L and (5.12±0.76)d], plasma amylase and uric amylase [(802.0±170.0), (4102.0±1126.0) U/L], the time of abdominal pain relief [(2.20±0.72) d] was lower in puerarin group (P<0.05). Conclusions The plasma ET and NO might play a key role in the development of AP. Therapeutic effect of puerarin is sure in AP.
