A cross sectional epidemiological study of 93 arc welders in a shipyard was conducted to observe the adverse effect of exposure to manganese welding fumes. Among them, 37 workers with paired controls were given the neurobehavioral tests. Air concentration of manganese in working place, hair manganese and platelet 5 hydroxytryptamine in both exposed workers and controls was also measured. The higher percentage of respiratory symptoms including sour throat and dyspnea in the welders were observed as compared with the controls. The results of neurobehavioral tests showed that the welders exhibited poorer performance in simple reaction time and Santa Ana dexterity tests than that in the controls. The hair manganese concentration was higher and the blood platelet 5 HT level decreased in the welders. In conclusion, symptoms in the welders might be related to the exposure of manganese. Long term exposure to manganese welding fume could cause the change in simple reaction time and Santa Ana dexterity tests. The hair manganese concentration could be used as a biological monitoring index of exposure to manganese.

核酮糖1,5-二磷酸羧化酶/加氧酶大亚基基因存在于叶绿体DNA中,它的转录作用能受光诱导。我们从蚕豆重组DNA中制备得到该基因片段后,应用Maxam和Gilbert的化学法分析了该基因5’端区的核苷酸顺序。结果表明叶绿体中光诱导基因的启动区具有一些共同特征。同时该大亚基肽链N端在进化过程中具有相当的守恒性。

Introduction: The instability of the joint is classified roughly into mechanical and functional. It is reported that the postoperative dislocation often occurs by the posterior approach of the THA and may be caused by functionality instability due to the injury of the periarticular soft tissue. We analyzed the joint position sense of the hip according to an approach of the THA and examined effect to give postoperative dislocation. Materials & Methods: 92 patients (184 hip joints) who received THA in our hospital were selected in the study. Cases in which position sensation measurements were insufficient were excluded. As for the classification, the posterior approach (PL groups) was 39 hips, anterolateral approach (AL groups) was 30 hips, and control group was 37 hips. Results: There was no significant difference between the AL group and PL group in the absolute reproduction angle error score (ARAES). The relative reproduction angle error scores (RRAES) for passive internal and external rotations and active internal rotation were significantly lower in the AL and control groups than the PL group. Discussion: This study was suggested that the hip joint position sense in the AL group was better retained for the preservation of the soft tissue.
