Cyclic adenosine monophosphate normally stimulates motility of spermatozoa. Its concentration in cervical mucus was studied by an isotopic competitive method in 15 normal women aged between 20 and 50 years. Values were very high, particularly in the periovulatory period, with a mean (+/-SD) value of 167.90 +/- 154.96 nmol/l. These are very high when compared with values in other biological fluids (blood serum and urine).

[Usefulness of paraffin embedding as complementary technic in the diagnosis of thyroid aspirates].

PURPOSE: To compare the diagnostic value of conventional direct cytologic smears and paraffin embedding in the preparation of samples obtained by fine needle aspiration (FNA) biopsy. METHODS: Direct smears and paraffin embedding preparations were examined from 100 thyroid lesions. In 9 cases, the FNA smears and paraffin embedding blocks were, in addition, compared with surgical thyroid specimens. RESULTS: The FNA samples were adequate for diagnosis in the great majority of cases (93/100). In 72 aspirates, both smears and paraffin embedding preparations were adequate. In 17 cases only he latter preparations and in 4 specimens only the smears were considered adequate. When both smears and paraffin blocks were available (72 aspirates), there was diagnostic agreement in 63 cases. Overall the diagnostic percentage of FNA/paraffin-block preparations was 95.7% and of FNA/conventional smears was 81.7%. Statistical analysis demonstrated that paraffin blocks increased the diagnostic accuracy of thyroid FNA (p < 0.01). CONCLUSION: Our data point out to the value of complementing conventional FNA smears with paraffin embedding preparations for the diagnosis of thyroid lesions.

[Acute Chagas' disease in an 80-year-old woman in Mexico. An anatomicopathological report].

A case of acute Chagas' disease, diagnosed by necropsy, in a 80-year-old woman, is reported. It is assumed that infection was acquired through triatomine bite in Zacoelo de Torres, Jalisco State, Mexico. There were lesions due to Aoffican trypanosomiasis in the heart, esophagus and bowel. Autonomic nervous lesions were detected in the esophagus and bowel. It is emphasized the importance of these findings in an area where few cases of megas were reported.
