Tissue CEA determination and cytophotometric DNA analysis of colorectal mucosa in patients with colorectal cancer.

Determination of tissue CEA content and cytophotometric DNA analysis of colorectal mucosa were carried out in 45 patients. Tissue CEA content in mucosa of tumor-bearing patients was significantly higher than in mucosa of the controls. In mucosa of the patients, tissue CEA content of transitional mucosa was significantly higher than that of background mucosa. Cytophotometric DNA analysis of colorectal mucosa disclosed that over 3c cells were not found in the upper third of the crypt in the controls, whereas appearance of these cells in the luminal surface of the crypt was characteristic in tumor-bearing patients. The population of over 3c cells in the upper third of the crypt was significantly larger in patients with multiple cancers or cancer accompanied by adenomas, than in the patients with solitary colorectal cancer.

[Fontanelle pressure in infants (Part II). Discussion on 6 cases of macrocrania].

From the results of ICP determination in 6 cases of macrocrania, it is evident that Lundberg's pressure wave (plateau wave, B wave) can be sufficiently adapted for evaluating abnormality under the semi-closed circumference like infants. ICP determination in the case of macrocrania with mild enlarged ventricles important for knowing pathologic changes. In particular, pressure variation and amplitude changes during REM period seem to be an interesting index for knowing the involvement of venous function. The increased ICP during REM period was also observed in a patient with holoprosencephaly having brain stem formation only, suggesting an important relationship between brain stem and increased ICP during REM period.

Ultrastructural and histochemical changes in the frog taste organ following denervation.

The fine structure of the taste organ in the Rana catesbeiana was observed by light and electron microscopy. The taste organ consists of three distinct cell types, the taste, supporting and basal cells as well as nerve elements. The present findings suggest that the taste cell might function not only as a chemoreceptor cell, but also as a paracrine cell. The basal cell also may have a dual function as both mechanoreceptor and paracrine cell. Furthermore, taste organs have been examined at intervals from 3 hrs to 120 days after sectioning of the glossopharyngeal nerves. The taste organs were almost intact throughout the experimental period after denervation and even after ceasing to produce impulses from chemical or mechanical stimuli. The dense-cored vesicles of the taste or basal cells, which may possess a paracrine action, still remain in the taste organ even 120 days after denervation. It can be concluded that the morphological integrity of the frog taste organ does not absolutely need the presence of the gustatory fibers in contrast to the nerve-dependent nature of the mammalian taste bud.

[A case of subependymoma of the septum pellucidum].

A 72-year-old-female was admitted because of slight disorientation and urinary incontinence. CT scan on admission revealed isodensity mass in the portion of the septum pellucidum and dilated lateral ventricle with patcy enhancement. A patient underwent the right frontal osteplastic craniotomy and subtotal removal of the tumor. Microscopical examination of the removed tumor tissue revealed a typical finding of subependymoma. In the previous literature subependymoma of the septum pellucidum has been reported only seven cases. We reported a rare case of subependymoma derived from the septum pellucidum, and histopathology and symptomatology of the tumor were discussed with the literature.

[Trial production of non-invasive monitoring system from the anterior fontanelle on intracranial pressure].

The aim of utilizing P-50 Statham transducer as one of the monitoring systems for intracranial pressure consists in the case for its attachment and simplified identification of the zero point and calibration which are of problem for operation as in the cases of electrocardiogram and respiration. The P-50 transducer is a semiconductor strain gage transducer which was developed for the measurement of blood pressure. By attaching the foot plate of it, the applanation principle could be applied and the measurement from the anterior fontanelle could be made feasible. The accuracy of the measurement in this manner could be confirmed by various experiments. Being a semiconductor strain gage, it could be made into an extremely small weight, which made it most adequate for continuous measurement. Although some problems have been left yet to be clarified relative to the method for the fixation, it can be deemed to be fully applicable as one of clinical monitoring systems for intracranial pressure.
