Comparative observation of the changes in serum lipid peroxides influenced by the supplementation of vitamin E in burn patients and healthy controls.

A microfluorescence analytical method was used to determine the contents of serum lipid peroxides and vitamin E in 35 severely burned patients, among whom 18 had been given vitamin E, and in 113 healthy blood donors. A comparative survey showed that the serum vitamin E decreased most significantly from days 6 to 8 postburn in both groups of burned patients, while the concomitant serum lipid peroxides increased significantly and reached a peak value. In control patients, the serum vitamin E levels were lower and lipid peroxides higher than those of healthy people (P less than 0.05) from days 20 to 22 postburn. At this time in the vitamin E-treated patients, the serum vitamin E levels increased and lipid peroxides decreased to the levels of healthy people (P greater than 0.05). Therefore, appropriate supplementation with vitamin E in burn patients is necessary.

[Preliminary study on red cell immune adherence inhibitory activities in serums of myasthenia gravis patients].

The serum inhibitory activities on RBC-C3b receptor rosette of healthy individuals were studied in myasthenia gravis (MG) patients. The serum inhibitory activities appeared in 65% of MG patients. The serum inhibitory activities of generalized type MG were higher than those of ocular type MG. It was also found that the serum inhibitory activities were correlated with the RBC-C3b receptor rosette rate and immune complex (CIC). Furthermore, it was identified that the CIC of MG serums possessed the inhibitory activity on RBC-C3b receptor rosette.

[A preliminary study on immune complexes in myasthenia gravis].

The levels of circulating immune complex from 43 patients with myasthenia gravis (MG) and 50 normal controls were detected by using ELISA based on bovine conglutinin. The levels of circulating immune complex in MG patients were higher than those in normal controls (P less than 0.01). Although the levels of circulating immune complex in generalized type MG were higher than those in ocular type MG, the difference showed no statistically significant. It was found that the levels of circulating immune complex, both generalized type MG and ocular type MG, were higher than those in normal controls respectively (P less than 0.01).

[Clinicopathologic study of 374 cases of intracranial tumors].

In this paper, 374 cases of intracranial tumor were studied retrospectively. The incidence of glioma (45.6%) was the highest, next was meningioma (19%) and pituitary tumor (12.3%). Astrocytoma comprised 73.5% of glioma. 75% of medulloblastoma and 54% of ependymoma occurred under 20 years of age, whereas 71.8% of meningioma, 44% of astrocytoma and 47.4% of metastatic tumor occurred between 21 to 50. The ratio of male and female was 1.69:1 except 0.8:1 of meningioma. 73.8% of all the lesions was located above the tentorium of cerebellum, the rest under it. Ninety one cases were followed. The 5 year survival rate was 25.3% (23/91). According to Kernohan's classification, the authors believe that astrocytoma can be divided into four grades, which is of great use in clinical diagnosis and prognosis. The other gliomas are only divided into benign and malignant. The results of surgery are related to tumor type and differentiation. Pituitary adenoma, meningioma, neurilemmoma and astrocytoma grades I and II have a good result by operation, while medulloblastoma, astrocytoma grades III and IV and metastatic cancer have a higher mortality.

[Clinicopathologic analysis of 487 thyroid tumors].

In this paper, 487 cases of thyroid tumor, 387 (79.5%) benign and 100 (20.5%) malignant, were analysed clinicopathologically. Benign thyroid tumor was divided into three types: papillary, follicular and atypical adenomas; malignant thyroid tumor into five types: papillary, follicular, undifferentiated, medullary and squamous cancers. In the benign variety, follicular adenoma had the highest incidence (98.2%) and in the malignant tumors, papillary cancer ranked first (62%). In this series, there were two cases of carcino-sarcoma. The sex ratio of male and female was 1:1.62 for the whole series, 1:1.70 for benign and 1:1.38 for malignant tumors. The peak age was 21 to 40 years with a median of 35 for benign and 31 to 50 years with a median of 43 for malignant tumors. For papillary carcinoma, the patients over 40 years of age comprised 50%. The typing of benign and malignant tumors is discussed. It is proposed that the occult cancer be classified according to histomorphology. Calcitonin by immunohistochemical technic or neural secretory granules by electron microscopy gives the most reliable evidence to diagnosis of the medullary carcinoma.
