The article deals with experimental data on design of the method used for detection of sperm, blood and vaginal secretions according to isoelectric points of acid phosphatases, differential diagnosis of ABO group antigens in "mixed" stains as well as detection of phenotype of red cell acid phosphatase by isoelectric focusing method.  相似文献

The authors reviewed at autopsy the causes of death of 274 patients with evidence of intravenous drug abuse who had been admitted to a large public hospital. There were 127 who died from diseases unrelated to intravenous drug abuse, and in 41% of these, chronic alcoholism was implicated. Deaths from overdose syndromes and drug-related organ pathology comprised only 11% of all cases. The mean age at death was 39 years. There was a male/female ratio of 3.6:1. Half of all patients died from infection--72 from acquired immunodeficiency syndrome (AIDS) alone. These findings indicate that persons hospitalized with a history of intravenous drug abuse usually die from causes other than overdose and that AIDS and chronic alcoholism are significant problems. Emphasis should be placed upon detecting "hidden" intravenous drug deaths to provide more accurate statistical information.  相似文献

A risk marker analysis of assaulted wives   总被引:1,自引:0,他引:1  
In the wife assault literature, a number of risk markers have been identified. Using the data of the female respondents to the National Family Violence Survey (n = 699), a multivariate analysis was performed to examine which risk factors best differentiated between women involved in nonviolent relationships, verbally aggressive relationships, relationships exhibiting minor physical aggression and severely violent relationships. High levels of marital conflict and lower socioeconomic status emerged as the primary predictors of an increased likelihood of wife assault. Research implications are discussed.  相似文献

The relation between domestic R&D and imports of technology is examined for 10 countries. Simple regressions revealed strong complementarity for each of the countries. Multiple regressions including GNP per capita and number of scientists and engineers were performed for the five countries with time series for all the variables. Strong complementarity was found between technology imports and domestic R&D and other variables for Japan and South Korea, weak for France, none for Germany and the US. Excluding government-financed R&D in the US resulted in a substitutive relation. Japan revealed a sharp decline in the ratio of technology payments to R&D spending; Korea is following in its steps. Complementarity appears to weaken in later stages as technology development strategies shift from dependent to imitative to autonomous or offensive technology development.  相似文献
