[Comparison of two nonspecific immune stimuli in antiblastic chemotherapy].
Antiblastic chemotherapy was combined with two aspecific immune stimuli, Levamisole Corynebacterium parvum, in 48 and 55 neoplastic patients respectively. C. parvum was found to be more easy to handle, particularly since Levamisole, albeit compensated by absolute lymphocytosis in many cases. In addition, C. parvum proved more effective in patients with lung and oro-pharyngeal neoplasias, whereas Levamisole appeared to be of greater use in breast cancer. Both stimuli led to improved coenaesthesia and performance status by comparison with a control group. It can thus be asserted that aspecific immunotherapy should have a place in the multidisciplinary approach currently sought.
Abstract This study estimates the employment effects of industry-specific, collectively bargained minimum wages in Germany for two occupations associated with the construction sector. I propose a truly exogenous control group in contrast to the control group design used in the literature. Further, a difference-in-differences-in-differences estimator is presented as a robustness test for occupation-specific and/or industry-specific, time-varying, unobserved heterogeneity. I do not find a significantly negative employment effect, even though the minimum wage is binding in (East) Germany. Possible explanations include substitution effects, non-compliance and models of monopsonic competition.
