The response of rat adrenal zona fasciculata and zona reticularis to oxytocin treatment.

The response of the adrenal zona fasciculata (ZF) and zona reticularis (ZR) to oxytocin (OT) was examined in male rats using a stereological method. The 10-day administration of 0.25 IU OT/100 g daily caused an enlargement of ZF due to cell hypertrophy associated with striking lipid accumulation.

[Echocardiographic detection of right atrial extension of hepatocellular carcinoma].

Right atrial extension of hepatocellular carcinoma is extremely rare and echocardiographic features of such extension have been described only in four patients. In this report, we present two patients with right atrial extension of hepatocellular carcinoma that was detected by echocardiography.

Stereologic analysis of ventral prostate of oxytocin-treated rats.

Ventral prostate response to oxytocin (OT) was examined in intact and castrated adult rats. The treatment consisted of 10 daily subcutaneous injections of 0.25 IU OT per 100 g body weight, which for orchiectomized rats began immediately after surgery.

[Echocardiographic diagnosis of angiosarcoma of the heart].

Cardiac angiosarcoma is the most common primary malignant tumour of the heart that is rarely diagnosed ante mortem. The authors present the case of a 73-year-old female with right atrial angiosarcoma that was followed-up echocardiographically for 20 months. Echocardiographic features suggestive of primary and metastatic malignant tumours of the right heart are discussed.

The response of rat adrenal medulla to oxytocin.

Effects of oxytocin (OT) on the adrenal chromaffin tissue of male rats were examined by coupled morphometric and biochemical techniques. Synthetic OT was administered in doses of 0.14 and 0.
