OBJECTIVES: To observe the plasmatic concentration of IL-6, IL-10 and IL-2 in the patient of chronic allergic rhinitis before and after acupuncture therapy. METHOdS: Cytokine levels were determined before and after treatment in 30 healthy volunteers (Group A) and 90 patients of chronic allergic rhinitis (Group B) with an increased plasma IL-10 level. Group B was then divided into 3 subgroups: 30 patients treated with real acupuncture (Group B1); 30 patients treated with sham acupuncture (Group B2); 30 non-treated patients (Group B3). RESULTS: The allergic subjects of group B1, compared with controls, showed a significant reduction of IL-10 after a specific treatment with acupuncture (P

In this article dedicated to the modeling of vertical mass transfers between the biofilm and the bulk flow, we have, in the first instance, presented the methodology used, followed by the presentation of various results obtained through analyses conducted on velocity fields, different fluxes, and overall transfer coefficients. due to numerical constraints (resolution of relevant spatial scales), we have restricted the analysis to low schmidt numbers (Sc=0.1, Sc=1, and Sc=10) and a single roughness Reynolds number (Re*=150). The analysis of instantaneous concentration fields from various simulations revealed logarithmic concentration profiles above the canopy. In this zone, the concentration is relatively homogeneous for longer times. The analysis of results also showed that the contribution of molecular diffusion to the total flux depends on the schmidt number. This contribution is negligible for schmidt numbers Sc≥0.1, but nearly balances the turbulent flux for Sc=0.1. In the canopy, the local Sherwood number, given by the ratio of the total flux (within or above the canopy) to the molecular diffusion flux at the wall, also depends on the schmidt number and varies significantly between the canopy and the region above. The exchange velocity, a purely hydrodynamic parameter, is independent of the schmidt number and is on the order of 10% of in the present case. This study also reveals that nutrient absorption by organisms near the wall depends on the schmidt number. Such absorption is facilitated by lower schmidt numbers.

Zinc and copper intakes and serum concentrations were determined at the 32th and 36th week of pregnancy in 96 healthy Thai women attending a prenatal clinic. dietary data from 3-day food records revealed that the mean dietary zinc and copper intakes in Thai pregnant women were 6. 9 and 1. 7mg/d (equivalent to 34 and 69% of Thai RdA), respectively. Fifty-five percent of zinc intake was from animal origin, whereas 59% of copper intake was from plant *** infants of the 64 women who were in the study until delivery, were all *** (>96%) of the maternal serum zinc and copper concentrations were within normal ranges. Only one woman at 32th week had low serum zinc level (d pregnancy outcome (birth weight and birth length). In this study, although the zinc and copper intake in most Thai pregnant women (99 and 58%, respectively) were less than two-thirds of the Thai RdAs, they were not at risk of suffering from zinc and copper deficiencies as determined by serum zine and copper concentrations, abnormal parturition and abnormal pregnancy outcome.

Soybean production systems that return plant residues to the soil surface are gaining in popularity. As these practices become more widespread, more crop and weed residues are being introduced into the upper soil profile. Greenhouse studies were conducted to determine the effects of varying concentrations of Palmer amaranth and pitted morningglory plant residues (aboveground portion of the plant) on soybean production. The study was arranged in a completely randomized experimental design with five treatments and five replications. Palmer amaranth and pitted morningglory residues were incorporated into soil at 20,000, 40,000, 80,000 and 160,000 ppm. Inert plastic residue at the same residue levels was included as a check. Soybean dry weight, leaf area and leaf tissue nutrient content were recorded during the study. A decrease in soybean dry weight and leaf area was observed as Palmer amaranth residue in the soil increased. Palmer amaranth residues of 160,000 ppm and 80,000 ppm in the soil significantly reduced soybean dry weight by 69% and 59%, respectively, and soybean leaf area by 60% and 57%, respectively. In contrast, pitted morningglory and inert plastic residues had no observable effect on soybean growth and development. This study demonstrated Palmer amaranth residues in the soil impacted early season soybean growth and development.

颈动脉体对化学信号的换能作用

颈动脉体可以将低氧和血液中其它刺激信号(可能包括低血糖)转换成不同强度的传入神经放电,沿心肺和神经内分泌反射的传入途径进入中枢,形成反射环路。低氧可抑制颈动脉体Ⅰ型细胞中的多种K+通道,这种作用可能有种属差异; K+通道的抑制使膜电位去极化,启动电压依赖性Ca2+内流,最后导致神经分泌和传入放电。离子通道埘低氧的反应可能是通过间接途径发生的,因此近期的工作集中在研究颈动脉体Ⅰ型细胞中在低氧感受中起关键作用的其它蛋白质。虽然有人认为来源于线粒体和／或NAdPH的活性氧(reactive oxygen species,ROS)起一定作用,但是它们在颈动脉体中转导低氧信号的证据还不足。目前正在对另外两种假设进行检验。第一种假设是血红素加氧酶2(haemoxygenase 2,HO-2)通过信号分子CO控制特殊K+通道的活动,而CO的生成量与氧分压高低有关。第二种假设是认为细胞能量感受器腺苷酸活化蛋白激酶(AMP- activated protein kinase,AMPK)起作用;低氧时AMP／ATP比值升高,激活AMPK,从而抑制Ⅰ型细胞的K+通道,传入放电增加。颈动脉体的细胞上具有丰富的对氧敏感的K+通道,低氧感受这个重要的细胞活动可以通过多条途径进行,在总反应中每种蛋白质也可能起不同的作用,例如不同蛋白质对氧的亲合力不同等。关于颈动脉体感受低血糖的机制尚不清楚,但最近有证据提示,它并非由K+通道关闭引起的,因此感受低血糖的机制和感受低氧的机制是不同的。
