    Notes: Abstract  Effects of a clay-lime spiked sewage sludge and fresh decomposable ryegrass on the mitigation of an acid drainage were studied in the laboratory. Treatments (dry ameliorant weight/leachate ratio) were: (1) sludge (air-dried) at rates of 0, 8, 16 and 24%, (2) ryegrass at 0, 1, 1.5 and 2% (dry weight), (3) sludge (at the above-mentioned rates) and 1.5% ryegrass mixture. Measurements of mitigation (according to the criteria of changes in pH, Fe, S, Al and heavy metals) made every 10th day for 100 days showed ryegrass/sludge combination the most effective while sustaining mitigation longest, with or without the influence of sulphate-reducing bacteria (SRB). Sulphate and Fe in the acid drainage decreased in the order: sludge+ryegrass〉sludge〉ryegrass by 180, 40, 19; and 96, 83 and 54% respectively, compared with controls. An 11-fold decrease in soluble Al was caused by the highest rate of the combined sludge-ryegrass treatment but Al was doubled by the sludge-only treatment, and only minimally affected (2% reduction) by the ryegrass-only treatment. For the sludge plus ryegrass treatments at the highest rate of application, pH levels increased significantly, from 2.3 to 〉7 units and within 20 days of SRB activation, the concentration of Co, Cu, Mn, Ni and Zn decreased 3-, 15-, 90-, 3- and 50-fold respectively.

    Notes: : This study was conducted to determine the fatty acid (FA) compositions and oxidative stabilities of cold-pressed cranberry, carrot, hemp, and caraway seed oils. The cold-pressed cranberry and hemp seed oils exhibited higher α-linolenic acid (18:3n-3) contents with levels of 22 and 19 g/100 g fatty acids, respectively. Cold-pressed carrot seed oil contained about 82% oleic acid and had the lowest total saturated fatty acids among all tested oils. Cold-pressed caraway seed oil had the greatest oxidative stability with an OSI value of 150 hours. In addition, cold-pressed carrot seed oil had the lightest color while hemp seed oil was the darkest among all the oils tested.

    Notes: Follicular lymphoid hyperplasia of the hard palate and oral mucosa: report of three cases and a review of the literature Aims: To bring to wider attention this uncommon, poorly understood entity which may closely resemble, clinically and morphologically, follicular lymphoma. Methods and results: We report three cases of follicular lymphoid hyperplasia of the hard palate and oral mucosa which caused diagnostic difficulties for the referring pathologists. The clinicopathological features are described and integrated into a review of the 16 previously recorded cases. The condition most commonly presents as a slowly growing mass situated in the posterior hard palate but may present with multicentric oral lesions and lymphadenopathy. Morphologically, it is characterized by a dense follicular lymphoid infiltrate within the lamina propria which may show the classical features of benign reactive hyperplasia, but not uncommonly, indistinct germinal centres, ill-defined mantles and a lack of tingible-body macrophages are features which may lead to an erroneous diagnosis of follicular lymphoma. Conclusions: Follicular lymphoid hyperplasia of the palate is a poorly recognized entity which is frequently confused with follicular lymphoma. Awareness of the entity combined with the use of immunohistochemistry for immunoglobulin light chains and bcl-2 protein allows a correct diagnosis to be made avoiding extensive investigation and aggressive treatment to the patient.

    Notes: Aims:  To report the clinical, pathological and immunohistochemical features of three cases of post-transplant T-cell lymphoproliferative disorder (T-PTLD) T-cell lymphoma with primary cutaneous presentation.Methods and results:  Three cases of primary cutaneous post-transplantation anaplastic large-cell lymphomas occurred in renal transplant recipients and were shown to display a T-cell immunophenotype; all were ALK 1 protein and EMA negative and two were Epstein–Barr virus positive using in-situ hybridization. Two displayed a CD4+ phenotype, two were focally CD56+ and all three were negative for the cytolytic enzyme granzyme B. In two cases monoclonality was established by T-cell receptor gene rearrangement study. All presented with nodular cutaneous involvement and all were ultimately fatal.Conclusion:  T-PTLDs are uncommon histological subtypes both in a general context and associated with cutaneous presentation. Our findings suggest clinicopathological and immunophenotypic similarities to primary cutaneous anaplastic large-cell lymphoma but with a progressive clinical behaviour similar to previously reported T-PTLD and to systemic nodal ALK– anaplastic large-cell lymphoma.

    Notes: A study of four cases of extra-orbital giant cell angiofibroma with documentation of some unusual features Aims: To document the clinical, light microscopic, immunohistochemical and ultrastructural features of four cases of extra-orbital giant cell angiofibromas. Methods and results: Sections of formalin-fixed paraffin-embedded specimens were studied by haematoxylin and eosin, reticulin and immunohistochemical stains. Electron microscopy was carried out in two cases on tissue fixed in formalin. The age of the patients ranged from 30 to 41 years. Two patients presented with a soft tissue swelling in the left groin, one patient had a left axillary soft tissue lump and one patient presented with a parotid lump. All lesions were well circumscribed and contained variably cellular and vascularized tissue composed of round to spindle cells with a patternless arrangement, scattered multinucleate giant cells and pseudovascular spaces conforming to the description of giant cell angiofibroma. Mononuclear and multinucleate tumour cells were both positive for vimentin and CD34; one tumour exhibited focal S100 protein and GFAP positivity. Both of the tumours examined by electron microscopy showed fibroblastic features, but in addition one contained cells having Schwannian features. All four patients were well without recurrent disease on follow-up (average 25 months). Conclusion: Giant cell angiofibroma shares many features with solitary fibrous tumour and giant cell fibroblastoma and shows a wider distribution than initially recognized. Rarely, Schwannian differentiation may be observed in these tumours.

    Notes: Summary T/natural killer (NK)-cell lymphoma is a subtype of non-Hodgkin's lymphoma, with frequent cutaneous involvement; it follows an aggressive course. Most cases are reported in Asia, and typically present with nasopharyngeal involvement. There is a distinct variant known as blastoid T/NK-cell lymphoma, which affects elderly, non-Asian patients, with absence of nasal involvement. We report a middle-aged caucasian man who had blastoid T/NK-cell lymphoma with nasal involvement.

    Notes: Abstract The interactions of two economically important gall midge species, the rice gall midge and the Hessian fly, with their host plants, rice and wheat, respectively, are characterized by plant defense via R genes and insect adaptation via avr genes. The interaction of a third gall midge species, the orange wheat blossom midge, with wheat defense R genes has not yet exhibited insect adaptation. Because of the simple genetics underlying important aspects of these gall midge-grass interactions, a unique opportunity exists for integrating plant and insect molecular genetics with coevolutionary ecology. We present an overview of some genetic, physiological, behavioral, and ecological studies that will contribute to this integration and point to areas in need of study.

    Copper stimulates human oral fibroblasts in vitro: a role in the pathogenesis of oral submucous fibrosis (2001)

    Notes: Abstract: Copper is implicated in the pathogenesis of several fibrotic disorders. Areca nut has been shown to have a high copper content and areca chewing is associated with oral submucous fibrosis (OSF). The effects of copper on human oral fibroblasts were investigated in vitro. Human oral fibroblasts were incubated with copper chloride (CuCl2) at concentrations ranging from 0.01 μM to 500 μM for 24 h, and in vitro cell proliferation was assayed by incorporation of tritiated–thymidine; soluble and non-soluble collagen synthesis was assayed using tritiated-proline. Addition of copper chloride at concentrations ranging from 0.1 μM to 50 μM increased the collagen synthesis by the oral fibroblasts compared with growth without copper (P〈0.05). The addition of copper chloride neither increased the synthesis of non-collagenous proteins by the fibroblasts nor influenced their proliferation rate. We conclude that copper upregulates collagen production in oral fibroblasts. This appears to be concentration dependent, with peak collagen synthesis at 50 μM CuCl2. These in vitro results taken together with the recent findings of copper in oral biopsies from OSF subjects support the hypothesis that copper in areca nut acts as a mediator of OSF.

    Notes: Abstract: Oral submucous fibrosis (OSF) is a chronic disease of the oral cavity and oropharyngx characterised by fibrosis in the submucosa leading to progressive limitation of the mouth opening. Interferon gamma (IFN-γ) is a known anti-fibrotic cytokine. In this study we have investigated: a) the effect of IFN-γ on collagen synthesis by arecoline-stimulated OSF fibroblasts in vitro (n=5), b) the effect of intra-lesional IFN-γ on the fibrosis of OSF patients (n=29) and c) the immunohistochemical analysis of pre- and post-treatment inflammatory cell infiltrates and cytokine levels in the lesional tissue (n=29). The results show that the increased collagen synthesis in vitro in response to arecoline was inhibited in the presence of IFN-γ (0.01–10.0 U/ml) in a dose-related way. In an open uncontrolled study intra-lesional IFN-γ treatment showed improvement in the patients mouth opening from an inter-incisal distance before treatment of 21±7 mm, to 30±7 mm immediately after treatment and 30±8 mm 6-months later, giving a net gain of 8±4 mm (42%) (range 4–15 mm). Patients also reported reduced burning dysaesthesia and increased suppleness of the buccal mucosa. The post-treatment immunohistochemistry showed a decreased amount of inflammatory cell infiltrate and an altered level of cytokines compared with the pre-treatment lesional tissue. The effect of IFN-γ on collagen synthesis appears to be a key to the treatment of these patients, and intra-lesional injections of the cytokine may have a significant therapeutic effect on OSF.
