[Postoperative radiotherapy for carcinoma of the uterine cervix].

During the period between 1972 and 1978, 226 patients were operated on for carcinoma of the uterine cervix at Hiroshima University, and 91 patients were treated by postoperative external irradiation. Patients with lymph node metastasis showed markedly lower five-year survival rates stage I: 44.4%; stage II: 45.0%) than those without lymph node metastasis (99.3% and 84.0%, respectively). In view of benefits of postoperative radiotherapy in the treatment of cervical cancer, only to the node positive and tumor rest patients is recommended.

[A case of ovarian carcinoma preceded by intracranial metastasis].

A 28-year-old woman with primary ovarian carcinoma which was found with intracranial metastasis is reported. The patient was operated on because of metastatic brain tumor with unknown primary lesion. Subsequently, left ovarian tumor was found, and left salpingo-oophorectomy was performed. The histological diagnosis was endometrioid carcinoma. A review of the literature shows that intracranial metastasis by ovarian carcinoma is very rare. The incidence is lower than 2.1%. The present case in which intracranial metastasis manifested itself before primary ovarian carcinoma seems to be extremely rare.

Silver-impregnation of the Golgi complex in epididymal epithelial cells of mice.

Localization of silver grains detected by the silver-impregnation method, a technique used to detect the classical Golgi apparatus, was examined with light and electron microscopy. Two types of silvered images of the Golgi apparatus were compared; each was obtained by Da Fano 's silver-impregnation method, and one was modified with Caulfield 's fixative during the preliminary fixation. Under ordinary light microscopy the images were very similar and showed the duplex structure of the Golgi apparatus which consists of an argentophil wall and argentophobe core. With electron microscopy, the relationship between the fine structure of the Golgi complex and the silver deposits was obtained in greater detail by the latter technique because the fine structure of the Golgi complex was retained. Many fine silver grains were detected in the cytoplasm adjacent to the Golgi complex, but none were present in the Golgi cisternae. This suggests that the argentophil wall of the duplex structure of the classical Golgi apparatus may be formed from argentophil substances that locate in the cytoplasm adjacent to the Golgi lamellae, and that the argentophobe core may be related to the Golgi lamellae.

[Ifosfamide in the treatment of small cell carcinoma of the lung].

A total of 36 cases with small cell carcinoma of the lung were treated with Ifosfamide. Fourteen cases (38.9%) out of 36 cases showed good or marked clinical response, and 120 mg/kg of Ifosfamide was necessary as a minimum dose to obtain effective response. As side effects of Ifosfamide, gastrointestinal disturbance (66.7%), depilation (66.7%), leukopenia (38.9%) and hematuria (36.1%) were observed. Mean survival time (M.S.T.) was prolonged by using Ifosfamide, comparing with the groups treated by with other anticancer drugs. Ifosfamide, therefore, should be used for the treatment of small cell carcinoma of the lung.

Glycogen depletion in exercising rats infused with glucose, lactate, or pyruvate.

The influence of an intravenous infusion of glucose, lactate, or pyruvate on the work capacity and rates of glycogen depletion in the liver and hindlimb skeletal muscles of rats has been studied. Running time to exhaustion at a speed of 21 m/min on a treadmill at a +10 degrees incline was prolonged by glucose infusion but shortened by lactate or pyruvate infusions. Blood glucose concentrations were only lowered in the terminal stages of the exercise, whereas at this point lactate was elevated. Declines in liver and muscle glycogen concentrations were retarded by glucose infusion but accelerated by either lactate or pyruvate infusions. In all cases a marked depletion of both muscle and liver glycogen existed at the point of exhaustion. It is concluded from the lack of any major elevation of glucose, lactate, or pyruvate in the blood of the rats during running that these materials were taken up and oxidized, presumably by the working muscles. These observations suggest that skeletal muscle can take up large amounts of glucose and when it is supplied from an external source this can exert a glycogen sparing effect on the liver and working skeletal muscles.
