    Notes: Abstract HLA class I and II expression was studied on 244 (177 primary and 67 metastatic) solid human tumours of different origin. Alkaline immunophosphatase (APAAP) and immunoperoxidase were used on cryostatic sections to stain MHC antigens. Monomorphic MoAbs were used against class I heavy chain, β2-microglobulin, DR, DQ and DP molecules. Class I expression was homogeneous on colon, melanoma and epidermoidal primitive tumours. Loss of HLA class I antigens was more frequent on basal cell carcinomas and sarcomas and was related to tumour differentiation on larynx carcinoma. Class I expression was heterogeneous on breast, larynx and stomach primitive neoplasias. Class I negative tumours were more frequent on metastatic than on primitive melanomas. Divergence of class I between primary tumours and autologous metastases was observed on melanomas, larynx and colorectal carcinomas. Class II expression was heterogeneous on all tumours and in a large number of cases was associated with high intensity of leukocytic infiltrate. HLA-DR expression was higher than HLA-DP and HLA-DQ (DR〉DP〉DQ) and was related to tumour progression. Four human tumour cell lines were modulated with recombinant interferon-γ for HLA class I and II antigens. Different HLA profiles were obtained: increased class I and II expression, increased class II or a low response. Finally, class I genes from 22 tumours were compared with autologous normal cells by Southern blot analysis: 12 tumours were class I positive and 10 negative. No clear differences in RFLP were observed that could be associated with class I rearrangement. The results are discussed in relation to the role that histocompatibility antigens may play in tumour progression and invasiveness.

    Notes: Abstract. Fatty change in donor livers is a risk factor for poor function after orthotopic liver transplantation. Various prevalences of steatosis have been reported in time 0 biopsies. The aim of this research was to determine, in a longitudinal study, the degree (percent of hepatocytes involved) and type (size of vacuoles) of fatty change shown by various histologic techniques. Four staining methods were used on sections from three liver wedge biopsies—at liver procurement, at the back-table, and after reperfusion—from 83 consecutive donor livers. Results in Sudan III-stained (SS) sections showed the greatest sensitivity (87.1%), negative predictive value (91.8%), and agreement rate (κ= 0.77) when compared with results in thin (1 μm) plastic-embedded toluidine blue-stained (TBS) sections. High-grade steatosis (〉30% steatotic hepatocytes) was identified in 49.4% of SS sections, 46.9% of TBS sections, 38.5% of frozen hematoxylin-eosin (H&E)-stained sections, and 20.7% of deparaffinated H&E-stained sections. Microscopic observations disclosed two types of steatotic pattern: (1) A predominantly small-droplet lipid vacuolzation (high-grade microsteatosis), similar to the steatosis associated with Reye syndrome, was seen in 29% of SS sections and 25% of TBS sections—approximately one-fourth of grafts; and (2) a combined pattern of large and small fat drops (high-grade macromicrosteatosis) was seen in 20% of SS sections and 22% of TBS sections. We concluded that moderate to severe steatosis is a frequent finding in donor livers. The difficulty in detecting lipidic microvacuoles in H&E-stained sections may be the reason for underestimating the grade of fatty change or even for diagnosing as normal some biopsies with high-grade microsteatosis.

    Notes: Abstract In this paper a surrogate to traditional utility optimization is presented. This approach is based on multiple criteria decision making techniques through a theorem which connects utility function optimization with compromise programming. Apart from common assumptions in the literature the only specific assumption underlying the approach seems realistic, and is markedly related to traditional analysis.

    Description / Table of Contents: Résumé Le traitement chirurgical des hernies inguinales évolue techniquement. L'introduction récente de la chirurgie peu invasive a ouvert une nouvelle voie, en proposant une technique par coelioscopie. ConÇue il y a quelques 15 ans, l'idée de fermer les orifices herniaires par la cavité péritonéale lors des laparotomies a fait l'objet d'une étude clinique. A suivi une étude expérimentale de fermeture de ces orifices par coelioscopie. Les résultats satisfaisants ont ensuite poussé à développer un appareil automatique, pouvant Être introduit dans un trocard, capable de fermer l'orifice par agraffage. L'application clinique de traitement coelioscopique des hernies inguinales était limitée au début au traitement des seules hernies obliques externes, mais depuis, a été étendue au traitement des hernies directes, crurales, obturatrices, étranglées, récidivantes et bilatérales. L'anatomie inguinale par coelioscopie, très différente de celle qu'on connaÎt par la voie d'abord habituelle, est passée en revue. Les détails techniques, ainsi que les bases d'autres techniques coelioscopiques sont présentées. Trente et une hernies inguinales ont été réparées par cette technique avec un suivi de 18 mois. Les résultats apparaissent satisfaisants dans 27 cas. Il y a eu 2 échecs techniques évidents, une récidive à 5 mois, due à une hernie par glissement, et un patient avec des symptÔmes de méralgie paresthétique. Les avantages et les inconvénients, essentiellement ceux de la coelioscopie en ellemÊme, par rapport à la technique classique sont décrits. Un suivi plus long est nécessaire pour juger des résultats de cette courte série.
    Abstract: Resumen El tratamiento quirÚrgico de las hernias de la región inguinal se mantiene en un proceso de modificaciones técnicas. El reciente advenimiento la cirugía mínimamente invasiva ha significado una posible nueva dimensión, al remplazar el abordaje inguinal por la laparoscopia. La tesis, concebida hace uno 15 años, fue sujeta a ensayo clínico cuando orificios herniarios abdominal coincidentes fueron cerrados durante laparoscopia. Esto fue seguido por un estudio experimental en el cual los orificios herniarios fueron reparados laparoscópicamente. Los satisfactorios resultados dieron origen al desarrollo de instrumentos grapadores que pueden ser introducidos a través de una cánula en la laparoscopia y utilizados para ocluir el orificio herniario abdominal. El ensayo clínico sobre el tratamiento de hernias por laparoscopia fue originalmente dirigido hacia el manejo de las hernias inguinales indirectas, pero posteriormente se ha ampliado para incluir las hernias directas, femorales, obturatrices, incarceradas, recurrentes y bilaterales. Se revisa brevemente la anatomía laparoscópica de la hernia inguinal, muy diferente de la perspectiva anatómica que se obtiene con el abordaje inguinal. Se presentan los detalles de la técnica operatoria, así como los fundamentos de otras técnicas laparoscópicas que han sido desarrolladas. Se han cerrado 31 orificios herniarios en un período de 18 meses. Los resultados aparecen satisfactorios en 27 casos, se presentaron fallas técnicas tempranas en 2, un paciente desarrolló recurrencia a los 5 meses, la cual posteriormente se demostró que se debía a una hernia por deslizamiento, y se presentaron síntomas de meralgia parestésica, de origen no determinado, en un caso. Se presentan las ventajas del procedimiento laparoscópico sobre el aproche tradicional; las desventajas son las de la laparoscopia misma y la carencia de un seguimiento a largo plazo.
    Notes: Abstract The surgical treatment of groin hernias continues to undergo technical modifications. The introduction of minimally invasive surgery had added a possible new dimension, replacing an inguinal approach by laparoscopy. Conceived some 15 years ago, the thesis was subjected to a clinical trial where coincidental abdominal hernial openings were closed at laparotomy. This study was followed by an experimental study at which time the openings were closed laparoscopically. The satisfactory results led to the development of a stapling instrument that could be passed through a cannula at laparoscopy and used to close the abdominal hernial opening. The clinical trial of treating hernias by laparoscopy was originally directed to the management of indirect inguinal hernias, but its use has since been expanded to include treatment of direct, femoral, obturator, incarcerated, recurrent, and bilateral hernias. The laparoscopic anatomy of the inguinal hernia, different from that seen by an inguinal approach, is briefly reviewed. The details of the operative technique are presented, as are the bases of other laparoscopic techniques that have evolved. Thirty-one hernial orifices have been closed and followed over 18 months. The results appear to be satisfactory in 27 instances. There were early technical failures in 2: One patient developed a recurrence after 5 months, later shown to be due to a sliding hernia; and symptoms of meralgia paresthetica of indeterminate origin appeared in one case. The advantages over the traditional approach are described; the disadvantages of the laparoscopic approach are those of laparoscopy itself and the absence of a long-term follow-up.

    Notes: Abstract. The yeast trehalose-6-phosphate synthase gene (TPS1) was engineered under the control of the cauliflower mosaic virus regulatory sequences (CaMV35S) for expression in plants. Using Agrobacterium-mediated transfer, the gene was incorporated into the genomic DNA and constitutively expressed in Nicotiana tabacum␣L. plants. Trehalose was determined in the transformants, by anion-exchange chromatography coupled to pulsed amperometric detection. The non-reducing disaccharide accumulated up to 0.17 mg per g fresh weight in leaf extracts of transgenic plants. Trehalose-accumulating plants exhibited multiple phenotypic alterations, including stunted growth, lancet-shaped leaves, reduced sucrose content and improved drought tolerance. These pleiotropic effects, and the fact that water loss from detached leaves was not significantly affected by trehalose accumulation, suggest that synthesis of this sugar, rather than leading to an osmoprotectant effect, had altered sugar metabolism and regulatory pathways affecting plant development and stress tolerance.
