[Silicon concentrations in maternal serum and breast milk in the postpartum period].

The silicon (Si) concentrations in maternal serum and breast milk were determined for 38 healthy postpartal women, 19 primiparae and 19 multiparae, by using inductively coupled plasma-atomic emission spectrometry (ICP-AES). The results are as follows: 1. The geometric mean (95% confidence interval) of the Si level in maternal serum was 9.

[Zinc and copper concentrations in breast milk and maternal serum in the postpartum period].

This study reports the contents of Zn and Cu in the breast milk and serum of postpartum mothers, 17 primiparas and 20 multiparas, at one week and at one month after delivery. Results were as follows. 1.

[Stereotactic aspiration using coordinate software for hypertensive intracerebral hematomas].

Stereotactic aspiration for intracerebral hematoma has become widely used due to improvements in computed tomography (CT). CT-guided stereotactic aspiration for hypertensive intracranial hematomas was performed in 46 cases. Stereotactic aspiration with coordinate software was carried out among 16 cases.

[Demonstration of a vascular lesion by intraoperative portable DSA in a case of intracerebral hematoma with impending herniation].

A nine year old boy with sudden onset of loss of consciousness was brought to the emergency room where he was in deep coma with bilateral decerebrated rigidity, and fixed dilated pupils. Computerized tomographic scan showed an intracerebral hematoma in the left temporal lobe associated with signs of uncal herniation. He was taken to the operating room immediately and craniotomy was started.

The effect of radiation therapy combined with natural killer cells against spontaneous murine fibrosarcoma.

The effect of radiation therapy combined with lymphoid cells against spontaneous murine fibrosarcoma (FSa-II) was investigated both in vivo and in vitro. In the in vivo experiment, syngeneic C3H mice were divided into 3 groups. Animals in the first group were injected with 1 x 10(5) tumor cells into the right hind leg.

[Barbiturate therapy in traumatic cerebral vascular disease: report of two cases].

We report two cases of traumatic cerebral vascular disease which were treated successfully with barbiturate. The first case sustained blunt trauma to the bilateral vertebral arteries, resulting in complete occlusion of both arteries. After ligation of the injured vertebral arteries, multiple cerebral infarction appeared.

A small temporal lobe glioma detected only by magnetic resonance imaging.

The authors were able to demonstrate a very small glioma (1.0 x 0.8 cm in size) of the temporal lobe using MRI.

[Cloverleaf skull syndrome with occipital bone cristae. Report of two cases].

Two cases of cloverleaf skull syndrome are reported. The patients were born with trilobed deformity of the skull associated with synostosis of the lambdoidal, coronal, and sagittal sutures in Case 1 and of the lambdoidal suture in Case 2. Both patients had hydrocephalus, low-set ears, and ocular hypertelorism.

Pathological studies on nephrotoxic serum nephritis accelerated with rabbit gamma-globulin in mice.

In order to characterize nephrotoxic serum nephritis accelerated with rabbit gamma-globulin in mice, histopathological studies were carried out 15 days after NTS injection, the time when increases in urinary protein and serum cholesterol and a decrease in serum albumin were apparent. Characteristic changes were widespread thickening of glomerular capillary walls and widening of mesangial areas, owing to deposits of mesangial matrixlike substances. The mesangial interposition into subendothelial areas and the resultant narrowing of the capillary lumen were shown ultrastructurally.

Congenital arteriovenous malformation of the scalp--case report.

A case of congenital arteriovenous malformation (AVM) of the scalp containing a complex vascular network is described. The AVM was totally removed, together with its feeding artery and draining veins. Congenital AVM of the scalp is rare; only 21 other cases have been reported since 1973.

[Unusual postoperative hemorrhage in a patient with ruptured aneurysm and hemophilia B].

A case of ruptured cerebral aneurysm with hemophilia B is reported, and discussion is made concerning the management of mild type hemophilia in surgical operations. A 41-year-old male came to our hospital with complaints of severe headache, vomiting, and transient consciousness disturbance. His dentist said the patient had a mild bleeding tendency when he was 30 years old, however no postoperative hemorrhage was repeated in appendectomy in his childhood.

Post-inflammatory arachnoid cyst of the quadrigeminal cistern. Observation of development of the cyst.

Arachnoid cysts of the quadrigeminal cistern are rare. Patients with this lesion are usually normal at birth, and signs of increased intracranial pressure (IICP) develop at about 4 to 12 months of age. However, there has been no report about this mechanism.

Studies on iridoid-related compounds. V. Antitumor activity of iridoid dervs. periodate oxidation products.

In the course of a modification study of iridoid glucosides to investigate their antitumor and antimicrobial activity, we found that about all metaperiodate oxidation products of iridoid glucosides which had no antitumor activity showed potent activity against the leukemia P388 in mice. They were found to be more active than the corresponding aglycones obtained by enzymic hydrolysis of iridoid glucosides. Among them, periodate oxidation product of sweroside showed the most potent activity, of which the maximum total/control (T/C) value was 198% at 200 mg/kg.

Marked cerebrospinal fluid collection associated with hepatic failure.

We report two cases with abnormal CSF accumulation in the cranium. One case had marked dilatation of the ventricular system, for which a ventriculoperitoneal shunt was carried out. The shunt was not beneficial and it turned out that the patient was suffering from ornithine transcarbamylase deficiency.
