[The content of catecholamines in the adrenergic plexuses of the spleen and intestines during cold and emotional stresses].
The content of catecholamines in adrenergic plexuses of the spleen and small intestine of rats has been studied histochemically using a computer analysis. It is shown that the content increases both during the short-term cold and emotional stress. Intraperitoneally administered guanethidine (10 mg/kg) does not prevent cold-induced accumulation of catecholamines in these adrenergic plexuses, but the emotional-induced one remains. Putative mechanisms of the catecholamine accumulation in the splenic and small intestinal adrenergic plexuses during different stresses are discussed. It is suggested that the cold stress induces an increase of the catecholamine synthesis in adrenergic terminals of prevertebral ganglion neurons, whereas emotional stress leads to the catecholamine uptake by adrenergic terminals from the blood.
[Chronic hematoma in Dandy-Walker cyst].
A rare case is reported of Dandy-Walker cyst of the posterior fossa with intracystic chronic hemorrhage. The serial computed tomography scans without contrast showed only the increase of the cyst. Only a C.T. Scan with contrast was the most helpful in making the correct diagnosis.
[Chlamydial proctitis in homosexual men].
We present 3 homosexual male patients, with lesions confined to the rectum, produced by chlamydia trachomatis. In the 3 patients the lesions were confined to the first 10 cm from of the anal margin, they were nodular, ulcerated and with stenotic tendency, difficult to differentiate macroscopically from a neoplasm. Multiple biopsy specimens from all patients reported chronic unspecific proctitis. In the 3 patients the presence of chlamydia trachomatis was confirmed by staining with lugol and giemsa from samples obtained by rectal smear, two of them presented simultaneous infection by neisseria gonorrhoeae, all were positive for HBsAg and one for HIV. Symptoms were tenesmus rectal urge, pain, thin feces and mucosanguinolent discharge. Treatment with 100 mg. Doxycycline BID for 21 days resulted in total remission in two patients; one patient with significant clinical improvement needed rectal bougienage.
