The serum acid phosphatase (ACP) activity and Hemoglobin (Hb) levels were measured in malaria patients and nonmalarial fever
patients. The results were compared with normal healthy control subjects. ACP was significantly increased (P < 0.001) in all the malaria patients. ACP was significantly higher in Plasmodium falcifarum malaria and mixed malaria when compared to Plasmodium vivax malaria. Hb levels were significantly decreased in all the malaria patients which indicates that malaria parasite uses host
erythrocyte Hb as a major nutrient source. There is negative correlation(r = −0.478) between ACP and Hb in malaria patients, which is highly significant. These results suggest that the measurement
of ACP could be used as a marker for malaria. 相似文献

探讨了环境光的存在对谷氨酸钠溶液的514nm绿色激光激发的拉曼光谱的影响。研究表明不同的环境光、自然光和室内荧光灯光均会对514nm激光拉曼光谱产生干扰,存在着特征干扰峰。自然阳光干扰较小;而荧光灯光表现为1127、2107cm^-1和2170cm^-1等3个明显尖锐的脉冲峰,不能忽略。建议在进行谷氨酸钠溶液514nm绿色激光拉曼光谱检测时,须在暗室或暗罩中进行,以完全隔离环境光的影响。 相似文献

The biological activity of the mineralocorticoid antagonist, spironolactone depend upon its metabolism. In this study the
effect of diuretic drug compound spironolactone on the acid and alkaline phosphatase in the testes of albino rat. The drug
spironolactone was administered orally daily for 7th, 14th and 21st days at the dose of 100 mg/kg body weight. Among them, the side effects of drug are that the degradation of alkaline phosphatase
in the testes; while acid phosphatase increased significantly may be due to 7a-thiospironolactone is a tissue metabolite of
spironolactone and may contribute to the testicular enzymes, therapeutic actions and some other side effects. It is suggested
that the decrease and increase of alkaline and acid phosphatase in the testes of albino rat are the due to the side effects
of spironolactone drug compound. 相似文献

The aim of the study was to evaluate the influence of rotavirus (RV) and soyabean trypsin inhibitor (TI) on lipid composition
and uptake of glucose and glycine in rotavirus (RV) infected malnourished (PEM) infant mice. Malnutrition was achieved in
animals by doubling the litter size. Cholesterol (Ch) and phospholipd (PL) contents, uptake levels of glucose and glycine
were determined in jejunum and ileum portion of small intestine. Increase in Ch/PL ratios was observed in PEM+RV group. The
levels became comparable in PEM+RV+TI as compared to PEM. Uptake levels of glucose and glycine increased in PEM animals. With
rotavirus (PEM+RV+TI group), the levels decreased which became comparable to PEM. Changes in uptake and lipid composition
with rotavirus and trypsin inhibitor may be responsible for altering membrane fluidity and organization during rotavirus diarrhea.
The results establish the importance of trypsin inhibitor during oral infection with rotavirus. 相似文献
