The author performed serially liver biopsies in adult dogs, using local anesthesia. He used Best´s Carmin for detecting glycogen. In some animals, he investigated the glycemia before each biopsy. He also studied the effect of several substances upon the glycogen content of the liver.

Locating sites dehydrogenase activity in the different structures of the human ovary, were studied by incubating tissue fragments Neotetrazolium succinate. The results showed: 1.-Mcderada dehydrogenase activity in the stroma. 2.-dehydrogenase activity in the follicular and theca cells of the developing follicle, rising rapidly with luteinization. 3.- No evidence-dehydrogenase activity in bodies found albicans. This method of dehydrogenase activity is related to the assumptions sisters production sites in the ovary, as well as a more general test of cell proliferation.

The comparative study between ninfocitograma colpocytology and 200 women, comprising 100 pregnant women in the three trimesters of pregnancy and 100 women with normal sexual cycle was performed. The sheets were examined, it counted 200 cells for each extended and was drawn graphs in relation to pictónico rate and maturity value found in the colpocitograma and the ninfocitograma in the 400 extended. These indices were very similar, so it is concluded that the ninfocitograma can successfully replace colpocitograma.
