[Reflections on the biosynthesis of morphine and idiopathic Parkinson's disease].

Based on a day-by-day, in-depth study of a clinical case, it was deduced that Parkinson's disease results in autointoxication, due to damage to morphine biosynthesis. Blood morphine levels should be studied in patients suffering from Parkinson's disease before treatment as well as in depressive patients (being the group most affected by Parkinson s disease) to achieve early preclinical diagnosis.

[Giemsa stain's 100th year].

Research work associated with the development of Giemsa stain is revived, with emphasis on the methylene blue polychromes. A short biographical sketch of Dr. Berthold Gustav Carl Giemsa is presented, along with the composition of his original formulation and its mec.

[Abortive activity of mimosine and its prevention (author's transl)].

18 out of 19 female mice treated orally with different levels of mimosine in the drinking water were fertile. Subcutaneous injection of mimosine (400 mg/kg) to 23 pregnant mice, in a single dose on days 5, 10, 15 or 17, resulted in death and resorption or expulsion of dead embryos, except in one, early inoculated. L-Phenylalanine (600 mg/kg) injected subcutaneously on day 17 prevented abortion in 4 out of 5 mice subsequently injected with mimosine.
