    Notes: The diffusion behavior at the Cu(In, Ga)Se2 (CIGS)/CdS interface of high efficiency CIGS thin film solar cells has been investigated using energy dispersive x-ray spectroscopy (EDX) and transmission electron microscopy. CdS layers were deposited on CIGS thin films using the chemical bath deposition (CBD) process. EDX analysis revealed that Cd was present in the CIGS layer approximately 100 Å from the interface boundary. In contrast to the diffusion of Cd, the Cu concentration decreased near the surface of the CIGS film, suggesting substitution of Cd for Cu atoms. These results are direct evidence of Cd diffusion into CIGS thin films during the CBD process. © 1999 American Institute of Physics.

    Notes: Abstract. The objective of the study was to examine the relation between the morphology of the common atrioventricular valve and regurgitation of the valve in patients with right atrial isomerism. We examined seven consecutive patients with documented right atrial isomerism who subsequently underwent postmortem examination during a 10-year period. The degree of regurgitation and the diameters of the common valve were evaluated via cineangiography, and the site of regurgitation was evaluated by echocardiography. The morphology of the common atrioventricular valve was assessed further at autopsy. Cineangiography revealed valve diameters ranging from 14.8 to 27.8 mm (mean 20.9 mm). Valvar regurgitation was revealed within 2 months of birth in all patients. Regurgitation abruptly worsened in three patients after placement of a Blalock–Taussig shunt or a central shunt and postintubation. Autopsies revealed that the common atrioventricular valve consisted of four leaflets in five patients, and three leaflets in two. The anterior leaflets were large and protruding in all patients, and the lateral leaflets were thickened in six. All patients had a mass consisting of the left lateral leaflets and chordae with direct attachment of the chordae to the ventricular muscle (the right lateral leaflet was attached to the ventricular muscle and immobile in one patient). The lateral leaflets clung to the ventricular wall and exhibited poor movement in six patients. Leaflets with poor mobility corresponded to the regurgitant valvar site as assessed by echocardiography in six patients; and the regurgitation in three patients with acute deterioration occurred at the valvar side with poor mobility. It is concluded that the common atrioventricular valve in patients with right atrial isomerism has morphologic characteristics that may be associated with valvar regurgitation and malignant potential for abrupt deterioration after replacement of systemic–pulmonary shunting.

    Notes: Abstract To determine the efficacy of the antiandrogen chlormadinone acetate as a treatment option for stage A prostate cancer, a retrospective analysis of 111 patients who received chlormadinone acetate was done. Of 55 stage A1 patients, progression was seen in one patient (1.8%) 8 years after the diagnosis. Six out of 56 stage A2 patients (10.7%) showed disease progression at 1–7 years (mean 68 months) after the diagnosis. Progression rates associated with antiandorgen therapy for stage A1 and stage A2 patients were lower than those without treatment reported in the literature. It could be assumed that antiandrogen treatment with chlormadinone acetate inhibited the progression.

    Notes: Abstract To assess testicular function in experimental varicocele rats, we used 31P magnetic resonance (MR) spectroscopy and compared MR spectroscopic parameters with flow cytometric DNA analysis. In vivo 31P MR spectroscopy and flow cytometric DNA analysis of testes were performed in 10 sham-operated and 9 induced varicocele rats. Although the testicular phosphomonoester (PM)/ATP ratio did not differ between sham-operated and induced varicocele rats, the phosphodiester (PD)/ATP ratio was significantly reduced and the inorganic phosphate (Pi)/ATP ratio was significantly increased in induced varicocele rats. There was no difference between the right and left sides. DNA flow cytometry showed a decrease in the percentage of haploid cells in induced varicocele rats, regardless of the side. This study indicates that in vivo 31P MR spectroscopy provides valuable information for assessment of testicular function.

    Direct effect of amezinium on rabbit urethra: Effect of estrogen and progesterone treatment (1996)

    Notes: Abstract The effect of amezinium, a new antihypotensive agent, and hormonal treatment on the female rabbit urethra was investigated. Cumulative dose responses were obtained for amezinium and norepinephrine on strips of muscle from the urethras of ovariectomized female rabbits by means of the tissuebath system. Amezinium enhanced the response to electrical field stimulation and showed a direct contractile response on the urethra. These responses were only about 20% of the maximum norepinephrine response. The contractile response to amezinium was completely blocked by prazosin. When rabbits were pretreated with estrogen, with or without progesterone, for 4 weeks, the response to amezinium increased to 40% of the maximum norepinephrine response. Although amezinium enhances muscle contractile responses to electrical stimulation, this effect is strong when amezinium is used alone; concurrent estrogen treatment improves the effects of amezinium.

    Notes: Abstract A serial urodynamic study was performed in 491 patients with uterine cancer following radical hysterectomy (RH) involving postoperative pelvic radiation (RH+RT) and extended hysterectomy (EH) for 10 years after these respective treatments. The following evidence is presented: (1) increased volume of residual urine and sensory impairment occurred 1–2 months after radical hysterectomy with or without radiation, but was rarely seen in the EH group: (2) increased residual urine volume in the RH group gradually subsided 1–3 years after the treatment, while the RH+RT treatment resulted in a slight reduction: (3) late maximum cytometric capacity in the EH and RH groups remained stable throughout the study, but the RH+RT group showed a lower capacity (P〈0.05) than the EH group, except in one set of determinations. (4) a high incidence of low bladder compliance in the RH group at 1–2 months decreased thereafter, whereas in the RH+RT group bladder compliance remained poor (23%) up to 7–10 years after treatment. In the EH group low bladder compliance was rarely seen: (5) sensory impairment, urinary incontinence and difficulty on urination remained unimproved in many patients in the RH+RT group, while the incidence of subsequent urological operations in the EH group was lower (P〈0.05) than in the RH+RT group. Based on these findings, EH appears to be more beneficial for the retention of normal bladder function and radical hysterectomy with postoperative radiation results in deterioration of bladder activity.

    Notes: Abstract A case of unilateral adrenal adenoma with foci of oncocytes in a 64-year-old woman is reported. The tumour manifested clinically pre-Cushing's syndrome with autonomous steroidogenesis which was insufficient to cause typical features of Cushing's syndrome. Whether the pathogenesis of oncocytes and adenoma cells, which were thought to have some metabolic deficiency in the present tumour, are linked remains to be determined.

    Analysis of Protooncogene c-erbB-2 in Benign and Malignant Human Prostate (1999)

    Notes: Abstract In this report, we characterized the c-erbB-2 gene and its product in prostatic cancer cells. Three prostatic cancer cell lines (PC3, DU145 and TSU-Pr1), one primary prostatic cancer and four benign prostatic hyperplasias (BPH) were studied. In reverse transcribed polymerase chain reaction, c-erbB-2 mRNA was demonstrated in all three cell lines and prostatic cancer tissues as well as BPH. The c-erbB-2 protein was expressed higher in prostatic cancer cells and tissues as compared with benign tissue by enzyme immunoassay, but it was not statistically significant. Immunohistochemical study, with the monoclonal antibody SV2-61γ that recognizes the extracellular domain of c-erbB-2, showed that all the prostatic tissues and cells had reactivity. Antigenicity was mainly in the cytoplasm. Analysis of genomic DNA failed to disclose gene amplifications or rearrangements of c-erbB-2 in both prostatic cancer and BPH. The sequence of amplified c-erbB-2, which corresponds to transmembrane domain, disclosed wild type in all prostatic cancer cells. These results demonstrate that although the number is limited, c-erbB-2 gene and protein are expressed in prostatic cancers and benign prostates. In the previous studies on c-erbB-2 expression in prostatic tissue, mainly conducted by immunohistochemistry, its frequency varies among each study, ranging from less than 0% to 100%. Therefore, to evaluate the c-erbB-2 in prostatic tissue precisely, it is also necessary to detect mRNA of c-erbB-2 as demonstrated in our study.

    Notes: Abstract Clear cell/compact cell ratio in histologic sections from 21 resected adrenocortical adenomas was assessed. Seven patients had Cushing's syndrome another 7 had primary aldosteronism caused by adrenal adenomas and 7 had non-hyperfunctioning adenomas. The results were correlated with the corresponding unenhanced CT attenuation numbers. There was a negative correlation between clear cell/compact cell ratios and unenhanced CT attenuation numbers. However, CT attenuation numbers did not show significant differences between cortisol-producing, aldosterone-producing and nonfunctioning adenomas. These facts suggest that clear cell/compact cell ratio in adrenocortical adenomas accounts for their attenuation number on unenhanced CT scans. However, it is difficult with the use of unenhanced CT attenuation numbers to differentiate cortisol-producing adenomas from aldosterone-producing and nonhyperfunctioning adenomas.
