Blood platelets in severely injured burned patients 总被引:2,自引:0,他引:2
Yoshiaki Takashima 《Burns : journal of the International Society for Burn Injuries》1997,23(7-8):591-595
Unbelievable decrease of blood-platelet in the severely burned patients during the treatment of skingrafting caused two patients to unexpected death. From the records of changes of platelet number, a certain ‘platelet curve’ was made. By observing the curve, our treatments of skingrafting were carried out during the stable period and from then on we had no death cases. 相似文献

An efficient BASIC program was established on Apple-Ⅱmicrocomputer with the CHESTAC-35F pulmonary function testing system tocalculate the time-constant histogram from the spirogram.By a set of analogousstudies,we confirmed that the recovered time-constant histogram was within onecompartment of the assumed one and that the root of mean square values of theresiduals between the experimental and model volume-time curves was 0.02.Infour healthy adult subjects,the mean value of time-constant histograms(TCx)hadthe variation coefficient 6.6%.The results show that our method is reliable andreproducible,and it can be used for clinical investigation. 相似文献

The recently developed method of total vertical projections is illustrated to estimate the total dendritic length of a human Substantia Nigra neuron. Next, the length of the different orders of dendritic branches, and the mean segment length for each order - commonly regarded as important parameters in neuron physiology - are also estimated. Finally, it is shown how to estimate the mean dendritic length in a population of neurons from vertical slices of arbitrary and unknown thickness. Being unbiased and highly efficient, the proposed methods offer interesting alternatives to current procedures used for the metric analysis of neuron arborizations. 相似文献

Liposomes as drug carriers in cancer chemotherapy have attracted considerable interest. To enhance the therapeutic effect of Adriamycin entrapped in liposomes (Lip-ADM) on human solid tumors, we investigated the therapeutic effects of Lip-ADM in combination with recombinant human tumor necrosis factor-alpha (rTNF-alpha), which is known to have specific effects on tumor vasculature. rTNF-alpha or saline solution was injected intravenously into nude mice bearing a human colon cancer strain, HC-1, at 1 hour before intravenous administration of Lip-ADM. The significant therapeutic effect of Lip-ADM in combination with rTNF-alpha was demonstrated by the evaluation with tumor growth curve and the actual tumor weights, in comparison with groups of mice treated with saline solution, rTNF-alpha alone, or with a Lip-ADM after saline. Levels of Adriamycin in tumor tissue in the Lip-ADM in combination with rTNF-alpha-treated group were higher than those in Lip-ADM with saline solution-treated group. 相似文献

低角度青少年特发性脊柱侧凸女性患者的骨密度分析 总被引:1,自引:0,他引:1
目的分析低角度青少年特发性脊柱侧凸(adolescent idiopathic scoliosis,AIS)女性患者的骨密度(BMD)和骨矿含量(BMC),探讨其与年龄、生长发育、人体测量学和侧凸角度等的相关性。方法研究对象为218例Cobb角15~40°的女性AIS患者。运用双能X线骨密度吸收仪测定非优势侧股骨颈和腰椎的BMC/BMD。探讨这两个部位的BMC/BMD与患者的年龄、生长发育、人体测量学和侧凸角度等的相关性。结果所有患者的年龄平均为(13.4±1.4)岁,Cobb角平均为(28.3±6.2)°。股骨颈BMD平均为(0.827±0.103)g/cm2,腰椎BMD平均为(0.887±0.124)g/cm2,显著低于同龄健康女性儿童;股骨颈BMC平均为(3.49±0.56)g,腰椎BMC平均为(29.78±7.37)g。患者的BMC/BMD与Cobb角无显著相关,而与体重、身高、Risser征、月经状况、BMI和年龄显著相关。逐步回归分析显示,体重和年龄是影响患者BMD的主要因素。结论低角度女性AIS患者存在全身性的骨量减低,且与Cobb角无显著相关,而与生长发育和人体测量学相关指标显著相关。这提示AIS患者的骨量减低与生长发育和低体重有关。 相似文献

The effect of swallowing a small quantity of water or of solid food (biscuit) on the renogram curve was observed in 177 patients. Swallowing provoked contraction of the renal pelvis in 63% of the kidneys with a pelvicalyceal system which was neither obstructed nor dilated, with expulsion of a substantial fraction of the contents within 30 s. This did not occur in obstructed or denervated kidneys, nor in patients with a high transection of the spinal cord. Evidence is adduced that this contraction is mediated reflexly. This effect may be used diagnostically to distinguish physiological dilatation from obstruction. The implications when performing and interpreting renography are discussed.

Although explosive isometric contraction provides little work toward the outside, force-time parameters of the rising phase
of the force-time curve may be able to predict muscle power. The purpose of this study was to examine the relationship between
muscle power with work (power grip) and force-time parameters during the rising phase in explosive isometric grip. Fifteen
healthy young adult males participated in this study. Power grip was measured using loads of 20%–50% of maximal voluntary
contraction (MVC) (peak isometric force). Subjects pulled explosively on a grip bar held with the second digital joints without
the thumb. Peak power was calculated from peak velocity and load. Explosive isometric grip was measured using a hand dynamometer.
Time-series data of both tests were sampled by an analog-to-digital interface. Both tests were performed with the subjects
seated with a sagittal and horizontal position of the arm supported by an armrest. Peak power in the power grip test tended
to be larger with an increase of the load, but there was no significant difference between 40% and 50% MVC. Only the peak
power in 50% MVC significantly correlated with peak grip force (r=0.52, p<0.05). The force-time parameters related to the peak rate of the rising force phase in explosive isometric grip significantly
correlated with the peak powers (30%–50% MVC, r=|0.58−0.78|). Peak rate of the rising force phase in explosive isometric grip
may be useful for predicting muscle power with loads between 30%–50% MVC. 相似文献

用“点值法”对健康工人473例[轻体力劳动工人(简称轻工)248例,重体力劳动工人(简称重工)225例]。作了流量一容积曲线和常规通气功能检查。结果表明:重工男女在40岁以后其高肺容积流量下降,30岁以后低肺容积流量上升,而且这些改变有随年龄增长而更加明显的倾向;轻工仅有个别年龄组的低肺容积流量上升。对7名健康坐位工作者模拟劳动的前倾姿势作多次通气功能检查,亦有明显高肺容积流量下降和低肺容积流量上升的现象,这一事实提示波速学说亦可应用于颈和躯干前倾进行重体力劳动工人的通气行为。 相似文献
