[A case report of volatile solvent psychosis].

A case (male, 27 years old) with chronic thinner intoxication, whose mental condition was reexamined in accord with a court order, is reported. He had been sniffing thinner from age 12 to 27. Since the age of 17, he experienced visual and auditory hallucinations without sniffing thinner.

Intraoperative manometry during laparoscopic operation for esophageal achalasia: does pneumoperitoneum affect manometry?

The effects of pneumoperitoneum on the lower esophageal sphincter (LES) were evaluated during laparoscopic operation for esophageal achalasia. Intraoperative manometry was performed in three patients who underwent laparoscopic cardiomyectomy with Dor's fundoplication and five patients who underwent laparoscopic cholecystectomy (LC). The LES pressure and the length of the high-pressure zone (HPZ) did not change during pneumoperitoneum in either the achalasia and the LC group.

[Adult-onset aqueductal stenosis caused by membranous occlusion in the aqueduct: a case report].

The authors report a case of adult-onset aqueductal stenosis caused by membranous occlusion of the aqueduct. The patient was a 35-year-old man, who suffered from progressive headache. On admission, computed tomography (CT) scan showed marked dilatations of the lateral and third ventricles.

[A case of cranial hypertrophic pachymeningitis with intracranial hemorrhage].

A case of cranial hypertrophic pachymeningitis of unknown etiology in a patient with 15-year history of headaches, cranial nerve palsies, and gait disturbance is reported. A 77-year-old woman was brought to our institute in a coma. CT revealed intracerebral hemorrhage in the right temporal lobe and thickening of the falx and tentorium.

Choroid plexus carcinoma in the lateral ventricle--case report.

A 68-year-old male presented with choroid plexus carcinoma in the left lateral ventricle manifesting as dysarthria and gait disturbance. Magnetic resonance imaging showed a homogeneously enhanced mass in the trigone of the left lateral ventricle. Selective left posterior cerebral arteriography showed the tumor was fed by the left medial posterior choroidal artery.

[A case of dural arteriovenous malformation in the anterior fossa associated with an occlusion of the unilateral middle cerebral artery with moyamoya phenomenon].

The authors report a case of dural arteriovenous malformation (dAVM) in the anterior fossa that was associated with an occlusion of the unilateral middle cerebral artery with Moyamoya phenomenon. The patient was a 79-year-old man referred to our department with an episode of consciousness disturbance and headache. Computed tomography scan showed intracerebral hematoma in the left frontal lobe, combined with left frontal subdural hematoma and subarachnoid hemorrhage.

Laparoscopic extramucosal myectomy with anterior fundoplication (Dor) for esophageal achalasia using intraoperative manometry.

Laparoscopic extramucosal myectomy with anterior fundoplication according to the Dor technique was performed on a 24-year-old-woman. Intraoperative inflation of a pneumatic balloon made the operative procedures such as extended submucosal dissection quite easy. Intraoperative gastrofiberscopy was useful for confirming that the remaining mucosal layer was not injured after completion of myectomy.

[A case of hemangioblastoma in the thalamus].

Supratentorial hemangioblastoma is encountered very rarely. About 80 cases in all have been reported. The authors present a case of supratentorial hemangioblastoma in the thalamus with gradually enlarging cysts.

[A case of brain abscess of the basal ganglia which resulted in disastrous outcome due to ventricular ruptures].

A case of deep-seated brain abscess that ruptured twice into the ventricle and resulted in death is presented. A 45-year-old man had experienced pyrexia and headache for 3 days before admission. On admission he was somnolent (GCS: 13) but there were no abnormal neurological findings except nuchal rigidity and Kernig's sign.

[Two cases of traumatic intracerebral pneumocephalus].

Two cases of traumatic intracerebral pneumocephalus, a rare complication of head trauma, are presented. Case 1: A 14-year-old boy had a strong concussion in his forehead due to a motorbike accident. Slightly obtunded on admission showing GCS 10, he became conscious in several days.

Aneurysm of the right gastroepiploic artery: a case report of laparoscopic resection.

A traumatic pseudoaneurysm of the right gastroepiploic artery in a 55-year-old woman was resected using laparoscopy. The durations of anaesthesia and operation were 260 and 220 min respectively. Blood loss was minimal.

Synthesis and Insecticidal Activity of Lignan Analogs (III).

Ten haedoxan analogs with the bond split between 2C and 3C of the 6-methoxy-2-methoxymethyl-3-(3,4-methylenedioxy)phenyl-1,4-benzodioxan-7-yl group of haedoxans were synthesized, and their insecticidal activity was assessed on the housefly. The inactivity of an analog having a 2-methoxy-5-(2-methoxyethoxy)-4-(3,4-methylenedioxybenzyloxy)phenyI instead of the 1,4-benzodioxan-7-yl group made it evident that the benzodioxane framework is essential for the activity of haedoxans.

Synthesis and Insecticidal Activity of Lignan Analogs (II).

The influence of the 6-methoxy-2-methoxymethyl-3-(3,4-methylenedioxyphenyl)-1,4-benzodioxan-7-yl group on the insecticidal activity of haedoxans was studied by synthesizing an analog without the (methoxymethyl)methinoxy moiety of the benzodioxanyl group to test for its activity on the housefly. The inactivity of the analog and its satellite compounds implies that the (methoxymethyl)methinoxy moiety is essential for the biological activity of haedoxans.

Syntheses of 2-Substituted 6/7-Methoxy-l,4-benzodioxan-7/6-carbaldehydes.

Five 2-substituted 6/7-methoxy-l,4-benzodioxan-7/6-carbaldehydes and 6-methoxy-l,4-benzodioxan-7-carbaldehyde available for the syntheses of insecticidal neolignan analogs were prepared from 4/3-benzyloxy-3/4-hydroxybenzaldehydes and l,4-benzodioxan-6-carbaldehyde, respectively.

[Left lower sleeve lobectomy for tuberculous stenosis of left main bronchus--a case report].

A 35-year-old women complained exertional dyspnea during medication therapy for pulmonary tuberculosis. Thoracotomy was done under the diagnosis of stenosis of the left main bronchus and of obstruction of the left lower bronchus due to bronchial tuberculosis. The collapsed inferior lobe of the left lung with fibrotic change was resected.

[The effect of recombinant epidermal growth factor in corneal angiogenesis].

Recent advances in genetic engineering techniques have enabled large-scale manufacture of human epidermal growth factor (hEGF), making possible the clinical use of this particular agent in treating a variety of corneal epithelial disorders. In view of future application to humans, it has to be determined whether hEGF could induce neovascularization in the cornea upon topical instillation, since the angiogenic effect of mouse EGF on the cornea in vivo has been reported. For this, a sheet of slow-release form polymer (EVA) containing hEGF was surgically implanted into the rabbit corneal stroma in search for subsequent corneal neovascularization.

[Anaphylactoid purpura and the complement system: particularly in terms of C3a and IgA (author's transl)].

We measured the immunoglobulin, beta1 C globulin, beta1E globulin, C3a, and CH50 in 20 patients with anaphylactoid purpura (Schönlein-Henoch purpura). IgA values proved to be elevated in 5 out of 11 cases. beta1 C globulin values were lower in 2 out of 8 cases and fell within the range of normalcy in the remaining 6 cases.

L-leucine: a neuroactive substance in insects.

A compound was isolated from the blood of silkworm larvae, Bombyx mori, which had been prostrated with DDT; this compound increased the spontaneous discharge in the isolated abdominal nerve cord of the American cockroach, Periplaneta americana. The compound was identified as L-leucine.
