三相流化床蒸发浓缩更年安提取物的研究

目的使用三相流化床蒸发浓缩中试装置用于更年安提取物的浓缩,探索最佳浓缩工艺。方法以浓缩器总传热系数、蒸发强度、浸膏的相对密度和最终产品中大黄素为指标,考察影响的主要因素:浓缩温度、分离室压力、加热蒸汽压力,并与普通的汽液两相外循环蒸发浓缩器进行比较。结果三相流化床蒸发浓缩最佳工艺为:加热蒸汽压力为0.15～0.25MPa,浓缩温度小于80℃,分离室压力为0.04～0.08MPa,颗粒直径0～0.020m。与普通外循环蒸发浓缩器相比,更年安醇提液的蒸发强度和总传热系数提高0.6倍,更年安水提液的蒸发强度和总传热系数提高0.3倍。三相流化床浓缩器连续运行300h,没有药物挂壁,而普通外循环浓缩器100h左右即会结垢。三相流化床蒸发浓缩工艺可以使浓缩液相对密度在1.35以上时一次出膏,勿需后续的真空球型浓缩罐再浓缩。更年安片中指标成分大黄素符合要求。结论三相流化床蒸发浓缩器具有在线防止结垢、效率高、浓缩时间短、流程简单,适应范围广等优点,可应用于中药浓缩。     

Characteristic expression of thrombomodulin in the muscle sarcoplasm in patients with the acute phase of rhabdomyolysis

The expression of thrombomodulin and neural cell adhesion molecule (NCAM) was studied immunocytochemically in biopsied muscle specimens from 10 patients with rhabdomyolysis with different etiologic factors, including 5 with malignant hyperthermia. We have already reported that thrombomodulin was expressed on regenerating muscle cell membranes as well as on vessel walls in patients with various neuromuscular diseases, including Duchenne muscular dystrophy, Becker muscular dystrophy and inflammatory myopathy. We found increased expression of thrombomodulin not only on the sarcolemma, but also in the sarcoplasm of a fair number of muscle fibers in the acute phase of rhabdomyolysis. The granular pattern of thrombomodulin expression in the sarcoplasm seems to be a characteristic finding in the acute phase of rhabdomyolysis. Most muscle fibers which expressed NCAM on the sarcolemma also expressed thrombomodulin. However, the muscle fibers which expressed thrombomodulin in the sarcoplasm did not express NCAM, and showed a degenerative appearance on electron microscopic examination. These results suggest that thrombomodulin is expressed in the sarcoplasm during the acute degeneration phase of rhabdomyolysis in addition to the expression on the sarcolemma during the muscle fiber regeneration as shown in our previous study, and the former process, which is characterized by the granular expression of thrombomodulin in the sarcoplasm, may be a characteristic finding in rhabdomyolysis.     

Directed sampling for electrolyte analysis and water content of micro-punch samples shows large differences between normal and ischemic rat brain cortex

Changes in sodium, potassium, and water content in brain tissue are important in the progression of pathology that follows ischemic stroke. Determining these parameters regionally in rodent models of experimental ischemia has been limited because typical tissue weights of more than 35 mg are too large. Identifying ischemic tissue to direct tissue sampling towards ischemic cortex is also represents a difficult generally unresolved area. We suggest that larger differences between normal and ischemic cortex of sodium, potassium, and water content than previously observed can be obtained from directed sampling of 2-mg brain tissue in a model of focal cerebral ischemia. In five rats, the middle cerebral artery and both common carotid arteries were occluded for 4.9+/-0.13 h (mean+/-SEM). Punch-sampling of 1-mm diameter tissue cores for water content (H(2)O%) by the wet-dry method, and [Na(+)] and [K(+)] by flame photometry, was guided by the observation of a subtle change in the surface reflectivity of ischemic cortex of quickly dried, 20-microm frozen brain sections, that was confirmed by MAP2 immunohistochemistry. The ratio of the lesion areas as determined by the reflective change and MAP2 immunoreactivity was 0.96+/-0.03 (n=5). In ischemic cortex H(2)O% was 79.9%+/-0.8%, [Na(+)] was 550+/-25 mEq/kg dry-weight, and [K(+)] 94.2+/-19.2 mEq/kg dry-weight (n=5), all significantly different from the values in border zone cortex, and in cortex contralateral to ischemic cortex and border zone (for all samples n=60, mean wet weight 2.037+/-0.046 mg). Differences between ischemic and normal cortex were 5.4+/-1.1%, 317+/-21 mEq/kg dry-weight, -304+/-27 mEq/kg dry-weight (n=5) for H(2)O%, [Na(+)], and [K(+)]. These differences between ischemic and normal cortex are 1.4-2.5, 1-3.11, and 1.4-3.5 times greater, respectively, than previous results obtained using samples weighing 35 mg or more. These results extend the association of sodium and potassium with ischemic brain edema in the rodent model, and show that these classical measurements can keep pace with the regionality of histochemical and morphological methods.
