    Fine structure of adrenergic nerve fibers in human periodontal ligament (1992)

    Notes: The presence of adrenergic nerve fibers was demonstrated ultrastructurally in the human periodontal ligament obtained from extracted premolar teeth from 8 young patients. The nerve endings were located close to arterioles. The results suggest that they seem to control blood flow in the human periodontal ligament.

    EFFECT OF TEMOCAPRIL ON HAEMODYNAMIC AND HUMORAL RESPONSES TO EXERCISE IN PATIENTS WITH MILD ESSENTIAL HYPERTENSION (1994)

    Notes: 1. This study was carried out to evaluate the effect of temocapril on haemodynamic and humoral responses to exercise in nine patients with mild essential hypertension (WHO stages I and II).2. After a 4-week placebo period, temocapril was administered at a dose of 1.0 mg once daily for 2–4 weeks. Graded submaximal bicycle ergometer exercise was performed before and after temocapril treatment, and the changes in arterial blood pressure, heart rate, cardiac output (CO), and systemic vascular resistance (SVR) were evaluated. In addition, the plasma norepinephrine (NE) level was determined both at rest and peak exercise before and after temocapril treatment.3. Both the systolic and diastolic blood pressure were reduced at rest and during exercise by temocapril treatment. No significant change in the resting heart rate and CO was observed, and the exercise-induced increase of these parameters was also not affected by temocapril. In contrast, the resting SVR was significantly decreased by temocapril, although the exercise SVR was similar during both temocapril and placebo treatment.4. Although there was no significant change in the plasma NE level with temocapril treatment, the exercise-induced increase of plasma NE was significantly suppressed by temocapril.5. These results indicate that temocapril reduces the blood pressure without causing any significant changes in the heart rate and CO at rest, and that it does not produce any changes in the haemodynamic response to exercise.

    Notes: Abstract This study examines the pulmonary hemodynamics during reimplantation and rejection following unilateral lung transplantation in dogs. Nineteen mongrel dogs were divided into three groups according to the method of treatment used: group 1 (n = 6) underwent modified autotransplantation of the left lung; group 2 (n = 6), allotransplantation without immunosuppression; and group 3 (n = 7), allotransplantation with immunosuppression. The pulmonary arterial blood flow and ventilation scores, assessed by chest X-rays, were measured for 2 weeks postoperatively. Pulmonary blood flow to the transplanted lung decreased slightly in group 1, whereas in group 2, it decreased sharply from the 3rd postoperative day (POD) and was almost completely absent by the 14th POD. In group 3, it decreased by 28% on the 1st POD but recovered gradually to 37% by the 14th POD. Ventilation scores were the same among the three groups on the 1st POD but in group 2, they decreased rapidly from the 3rd POD. This change correlated well with that of the pulmonary arterial (PA) flow, although the ventilation score changed after the PA flow did. In conclusion, rejection was reflected earlier and more distinctly by the changes in PA flow than by chest X-rays.

    Notes: Abstract We report herein a rare case of primary esophageal malignant melanoma in a 49-year-old Japanese woman who presented with a 3-week history of dysphagia. Esophagogram and esophagoscopy demonstrated a polypoid tumor in the upper to mid-thoracic portion of the esophagus, and a radical subtotal esophagectomy was performed through a right thoracotomy. Histological and immunohistochemical studies proved this tumor to be a primary esophageal malignant melanoma. She received no postoperative adjuvant therapy and no signs of recurrence have been clinically observed for the 22 months since her operation.

    Synergistic effects of benzalacetone and benzophenone on the electrocrystallization of tin from acid stannous sulphate solutions (1994)

    Notes: Abstract The synergistic effects of two kinds of aromatic ketones (benzalacetone (BA), benzophenone(BP)) and N,N-bis(polyoxyethylene)octadecylamines (POOA) on the surface morphology and the crystal orientation of electrodeposited tin from acid stannous sulphate solutions have been studied by electrochemical methods, scanning electron microscopy and X-ray diffractometry. BA itself had no effect on the reduction of tin (II) ions, but the reduction product of BA had a strong inhibitory effect on the reduction of tin (II) ions. However, the inhibitory effect of BP was stronger than that of the reduction product of BP. POOA induced a uniform deposition of tin over the whole surface, but the crystal grain size and the surface roughness of electrodeposited tin were relatively large. On the other hand, fine-grained and smooth electrodeposited tin, which had a preferred orientation with the (10 0) plane parallel to the surface, were obtained from acid stannous sulphate solutions containing POOA, BA and BP due to the synergistic effects of the three kinds of adsorbed species. It was found that BA has a levelling action and BP has a grain refinement action.

    Zinc increases the longevity of unfertilized sea urchin eggs (1991)

    Notes: Summary We have found that Zn2+ prevented lysis of unfertilized sea urchin eggs, and the eggs retained the ability to form fertilization membranes and to divide. SDS polyacrylamide gel electrophoresis showed that proteolysis of several proteins accompanied egg lysis, but Zn2+ inhibited this proteolysis. Therefore, Zn2+ blocks protease activity directly or indirectly and thereby prolongs the longevity of unfertilized sea urchin eggs.

    Radiographic features of experimentalCandida arthritis in rats (1993)

    Notes: Abstract Sprague-Dawley rats were inoculated intravenously (i.v.) withCandida albicans, and limb joints showing signs ofCandida-induced arthritis were subjected to radiographic and histologic examination. New bone formation and bone resorption were morbidly enhanced in bones sampled from the arthritic joints. Sparsely distributed needle-shaped calcified deposits began to be formed on bony surfaces in parallel with the onset of joint swelling. The calcified deposits gradually became denser and then covered the bony surfaces almost entirely, giving rise to an exostosis-like profile. In addition to the new bone formation, bone resorption was also observed in regions adjacent to the sites of new bone formation, and punched-out bone lesions were produced. Eventually, severe deformation of joint bones due to new bone formation and bone resorption was evident. Reflecting these unusual radiographic changes, abundant osteoblasts and osteoclasts were demonstrated histologically in the bones. On the basis of these results, possible mechanisms for the induction of arthritis byCandida infection are discussed.

    Intra-operative radiation therapy for malignant brain tumours: Rationale, method, and treatment results of cerebral glioblastomas (1994)

    Notes: Summary In radiation therapy for malignant brain tumours, the dose of radiation that can be safely delivered to a tumour is limited by the radiation tolerance of the adjacent normal brain tissue. Among various radiation modalities to produce local tumour eradication without unacceptable complications, we chose a large, single irradiation dose during the operation (intra-operative radiation therapy, IORT). In contrast to X-ray or Cobalt-60 gamma ray irradiation, IORT with a high-energy electron beam delivered by the Shimadzu 20 MeV betatron provides acceptable dose homogeneity with rapid fall-off of the radiation dose beyond the treatment volume. Thus, IORT has the advantage of precise demarcation of the target volume, minimum damage to surrounding normal tissues, and a high absorbed target dose (15–25 Gy in 5–10 min). On the basis of our experience with 170 patients treated by IORT, we established the treatment indications and method in patients with malignant brain tumours. IORT with a dose of 15–25 Gy was delivered to widely resected tumours followed by external radiation therapy. No acute or subacute complications were observed. Treatment results of 30 patients with glioblastoma treated by IORT (mean 18.3 Gy) combined with external radiation therapy (mean 58.5 Gy) resulted in a median survival of 119 weeks and a 2-year survival rate of 61%.
