The pharmacological concept of \"mild\" exogenic ovarian stimulation by low dosage at the threshold of effectiveness should deserve more attention, last but not least, for breeding aspects.

The cannulas are manufactured of Type B 400/40 K PVC paste by means of a casting technique.

The investigations were undertaken with a view to differentiating T-lymphocytes and macrophages by differentiated activity on acid unspecific alpha naphthylacetate esterase. Lymphoma specimens were cytologically evaluated under semi-quantitative or quantitative aspects. Evidence was provided to the existence of correlations between intensity of Marek's disease lymphomas and their relative contribution to lymphocytes, lymphoblasts, and macrophages. The amount of lymphoblasts was found to go up along with advancing lymphoma proliferation, while the amounts of lymphocytes and macrophages went down. Moderately pronounced lymphomas contained 16 percent macrophages on average, whereas only about 8 percent were recordable from highly pronounced lymphomas.
