[Analysis of trace elements and composition of protein in sika blood].

The levels of trace element and protein were determined in eight male sikas. The results revealed that the levels of phosphorus, zinc, copper, ferrin and manganese were 2.68 mmol/L, 51.3 mumol/L, 21.4 mumol/L, 255.6 mumol/L and 0.16 mumol/L respectively and which were significantly higher than the human normal values. Serum levels of albumin and globulin were 34.9 g/L and 35.5 g/L respectively. Among them, the level of gamma-globulin was the highest (25.2%) which was threefold than the human serum normal value. From the above results, sika blood has great value in medicinal use.

Examination of the cutaneous absorption of copper after the use of copper-containing ointments.

Because copper-containing ointments are frequently used in anthroposophical medicine, a phase I trial to investigate the cutaneous absorption of copper was conducted. Sixty-one volunteers were randomized [group A: 0.4% copper (I) oxide, 13 men and 18 women (19-55 years); group B: 20% elementary copper, 11 men and 19 women (18-70 years)]. The ointment was applied over a 4-week period followed by a 4-week wash-out phase. Serum and urine copper concentrations were measured by atomic absorption spectrometry and hair copper concentration by inductive coupled plasma mass spectrometry. For statistical analysis, the Student t test for related random samples was used; alpha = 0.05 was chosen for the standard error. In group A, an increase of copper in serum and scalp hair and a decrease in urine were found in the study period. The mean serum concentration in all premenopausal women using oral contraceptives was above normal. In group B, the serum copper concentration increased significantly; in urine, it decreased, and in scalp hair, it remained stable. A higher level of serum copper was found in female volunteers using hormonal contraception. Treatment with the 2 different ointments did not cause toxic irritations on the skin, and it can therefore be deduced that the appropriate application of ointment preparations containing copper in concentrations up to 20% do not present a toxic risk.

Deficiencia de cobre en bovinos: su tratamiento comparativo con cuprum y cobre alopático / Deficit of copper in bovine: comparative treatment with cuprum and allopathic copper

En un establecimiento con deficiencias primarias y secundarias de cobre se compararon dos tratamientos, uno homeopático y el otro alopático, frente a testigos no tratados. De los resultados se desprende: 1.- En el tratamiento alopático la ganancia diaria de peso (G.D.P.) es mayor que en el tratamiento homeopático al comenzar el ensayo. 2.-Hacia el final del mismo, las G.D.P., es mayor en el tratamiento homeopático que en el alopático. 3.- Ambas G.D.P. son mayores que la de los testigos
