    Notes: Some degradation modes of 1.3 and 1.55 μm buried heterostructure distributed feedback (DFB) lasers grown by liquid-phase epitaxy are clarified. A degradation mode induced by the inhomogeneous optical-field distribution along the laser cavity is found to exist in DFB lasers. In most DFB lasers, the interface degradation between first growth-step (double heterostructure) layers and second growth-step (burying) layers occurs in the same manner as Fabry–Perot lasers.

    Notes: Herpes simplex viral DNA was detected in biopsy specimens obtained from four patients with Kaposi's varicelliform eruption using an in situ hybridization technique with btotinylated complementary DNA probes. Herpes simplex viral DNA was consistently found almost exclusively in the nuclei of giant cells and balloon cells in vesicles during day 2, 5 and 7 of the disease. In the nuclei, the viral DNA staining pattern was granular or agglomerate. No positive staining was observed in the cytoplasm.

    Examination of previous caesarean section scars by ultrasound (1988)

    Notes: Summary We examined 84 lower segment caesarean section scars by ultrasonography near term. Seventy scars showed good healing with a thickness of the lower uterine segment of more than 3 mm; 14 scars showed poor healing with a thickness of less than 2 mm and loss of continuity. Among 70 patients with good healing, 24 patients delivered vaginally but the remaining 46 patients have had repeat caesarean sections for other obstetric indications. Intraoperative findings in these 46 patients were as follows: Grade I (no thinning of the lower uterine segment), 42; Grade II (thinning and loss of continuity of the lower uterine segment but fetal hair not visible), 4; Grade III (thinning of the lower uterine segment and fetal hair visible), 0. Fourteen patients with poor healing had repeat caesarean sections. Intraoperative findings in these 14 patients were as follows: Grade I, 0; Grade II, 9; Grade III, 5. These results indicate that ultrasound examination detect thinning of the lower uterine segment and may help to determine management.

    Description / Table of Contents: Zusammenfassung Es wird eine einfache Methode zur Typisierung von Haptoglobin (HP) mittels Isoelektrofokussierung beschrieben. Das Serum wird mit Clostridium perfringens Neuraminidase (CPN), sodann mit Dithiothreitol (DTT) vorbehandelt und anschließend der Polyacrylamidgel-Isoelektrofokussierung (PAGIF) unterworfen. Die Banden wurden durch Immunoblotting sichtbar gemacht. Die Methode erwies sich als erfolgreich bei der HP-Darstellung von selbst 2 Monate alten Blutspuren. Durch eine leichte Modifizierung ist es möglich, neben HP auch die Komplement-Komponente C81 und Faktor I (IF) darzustellen. Immunoblotting ergab außerdem eine dauerhafte Darstellung der HP-Banden. PAGIF ist daher als forensische Routinemethode zur HP-Typisierung geeignet.
    Notes: Summary A simple isoelectric focusing method for haptoglobin (HP) typing is described. Serum was pretreated first with C. perfringens neuraminidase (CPN) and then with dithiothreitol (DTT). The treated serum was subjected to polyacrylamide gel isoelectric focusing (PAGIF), and the band patterns were detected by immunoblotting. The method could be successfully applied to HP typing of bloodstains as old as 2 months. A slight modification of it enabled HP, complement component C81, and factor I (IF) to be typed simultaneously. The immunoblotting facilitated preservation of HP patterns. Thus, the PAGIF method for HP typing is suitable for routine use in the forensic laboratory.

    Ultrasound examination of caesarean section scars during pregnancy (1991)

    Notes: Summary Two hundred and sixteen transverse caesarean section scars were examined sonographically near term by a conventional method (175 scars) and a new method (41 scars). The new method consisted of obtaining a transabdominal longitudinal scan by the conventional method and also by a 3M conductor, a transabdominal frontal scan to give a surface view of the scar, and transperineal and transvaginal longitudinal scans. The new method was used from 16 weeks of gestation onwards. Of 41 scars scanned by the new method, 31 showed good healing, being more than 2 mm in thickness throughout; 10 scars showed poor healing with a thickness of less than 2 mm and loss of continuity. Of 31 patients with good healing, 8 delivered vaginally and the remaining 23 patients had repeat caesarean sections for other obstetric indications. All patients with ultrasound evidence of poor healing had repeat caesarean sections. At operation the thickness of the lower uterine segment was measured with ophthalmic calipers. There were 4 false negative results (4/83: 4.8%) and 1 false positive result (1/43: 2.3%) with conventional ultrasound and no false positives or false negatives with the new method.

    Morphology and modes of cell proliferation in earliest signet-ring-cell carcinomas induced in canine stomachs byN-ethyl-N′-nitro-N- nitrosoguanidine (1991)

    Notes: Summary Signet-ring-cell carcinomas were induced in the stomach of 12 beagle dogs by p.o. administration ofN-ethyl-N′-nitro-N-nitrosoguanidine (ENNG), and the morphology and modes of cell proliferation in an incipient stage of cancer growth were studied with bromodeoxyuridine (BrdUrd) incorporation. From 5 to 27 months after the completion of 8 months' carcinogen treatment, minute carcinomas were found in the stomachs of 9 dogs. Before sacrifice, the dogs were given a single or repeated i.v. injections of BrdUrd for 1–3 days. Minute signet-ring-cell carcinomas were found to form a layered structure, in which the cancer cells proliferated in the lamina propria at the gland-neck level and differentiated to postmitotic signet-ring cells at the upper and lower levels of the mucosa. From repeated injections of BrdUrd, the time required for all the proliferative cells to be labelled with BrdUrd (reflecting the maximum cellcycle time) was estimated to be 1.7 days for the normal glands, and 2.7 days for minute signet-ring-cell carcinomas. From the labelling index with BrdUrd as well as from the morphology, earliest carcinomas were identified in the single gland. There remained atrophic normal epithelium commonly in the single-gland lesions. Proliferative atypical cells appeared to be shed into the stroma passively through the atrophy and subsequent collapse of the gland rather than through active invasion. This may be a reason why cancer cells in minute signet-ring cell carcinomas preserved the normal pattern of cell renewal movement to form the layered structure.

    Description / Table of Contents: Zusammenfassung Es werden einfache schnelle Methoden zur G3m(21)-Typisierung mit enzymisch markierten monoklonalen Anti-G3m(21)-Antikörper beschrieben. Bei G3m(21)-Typisierung mit ELISA wurden Mikrotitertüpfel mit zu untersuchendem Antigen direkt überzogen. Das Antigen wurde mit dem enzymisch markierten monoklonalen Antikörper nachgewiesen. Eine Punkt-Immunobindung Methode wurde geschaffen, um das Prozedere noch weiter vereinfachen zu können. Das Antigen in der Probe wurde auf einer Nitrozellulosemembran appliziert und mit dem enzymisch markierten monoklonalen Antikörper erfolgreich nachgewiesen. Diese Methoden, besonders die Punkt-Immunobindung, sind für die forensische Praktik geeignet.
    Notes: Summary Simple, rapid methods are described for G3m(21) typing with peroxidase-labeled monoclonal anti-G3m(21) antibody. In G3m(21) typing by ELISA, microtiter wells were coated directly with the test antigen, which was detected with the enzyme-labeled monoclonal antibody. To further simplify the procedure, a dot immunobinding method was developed. The antigen in the test serum applied onto a nitrocellulose membrane was successfully detected with the enzyme-labeled monoclonal antibody. These methods, particularly the dot immunobinding, are suitable for forensic casework because they are rapid and simple and require no technical skill.
