Abstract Small cell neuroendocrine carcinomas (SCNC) are composed of round to spindle-shaped cells with features of both neuroendocrine and epithelial neoplasms. SCNC can be found in basically all epitheloid organs; however, the vast majority arises in the lung, while extrapulmonary (EP) localization is rare. Small cell lung cancer (SCLC) and EP SCNC are considered one histological entity and are treated similarly. Despite the high initial response to chemo- and radiotherapy, most patients relapse after short remission, and overall prognosis is dismal. Clinical trials employing high-dose chemotherapy (HDCT) followed by autologous stem cell transplantation (auto-SCT) neither demonstrated a clear benefit nor clarified its significance in SCLC. The role of intensified treatment in EP SCNC has not been specifically addressed in detail. Conversely to SCLC, some subgroup analyses indicated that patients with EP SCNC might benefit from intensive treatment. We analyzed a total of 22 patients: 8 with EP SCNC (group A; m:f 3:5; median age 36 years (y) [range 22–56]) and 14 patients with SCLC (group B; m:f 10:4; median age 55 y [40–63]), all undergoing HDCT with auto-SCT at our single center from 07/90–01/05. A control group C consisted of 30 patients with EP SCNC (m:f 21:9, median age 66 years [32–81], who received different standard treatments without auto-SCT. All group A patients had stage IV disease (liver n=5, lymph nodes n=4, pancreas n=1, orbita n=1, bone n=1, kidney n=1). Two of these patients received additional local radiotherapy. In group B, 7 patients had limited and 7 patients extensive disease, (stage I (n=1), II (n=2), III (n=10), IV (n=1). HDCT with VIC (etoposide, ifosfamide, carboplatin; n=21), or CCT (carboplatin, cyclophosphamide, thiotepa; n=1) was followed by infusion of a median 3.2x10^6 CD34+ cells. Prophylactic radiotherapy was performed in 12 patients (mediastinum n=11; brain n=10). With a median follow-up (FU) of 48 months (7–152) for group A and 85 months (0–170) for group B, 5/8 (63%) of patients with EP SCNC (group A) are alive and in complete remission (CR), compared to 5/14 (36%) SCLC patients (group B). Best response ever achieved after HDCT was a CR in 5/8 (63%), a partial remission (PR) in 2/8 (25%) and stable disease (SD) in 1/8 (12%) in group A. In group B, a CR was attained in 11/14 (79%), a PR and a SD in 1/14 (7%) patients, respectively. In the conventionally treated control group C, a transient PR was achieved in 5/30 (16%), and after a median FU of 9.7 months, only 2/30 (6.7%) EP SCNC patients are alive. Our analysis suggests that selected SCNC patients may benefit from HDCT, particularly when integrated into multimodal treatment concepts. The remarkably favorable outcome in patients with EP primary site, even when HDCT was implemented as salvage treatment warrants further studies on the role of HDCT in SCNC. Careful attention will have to be paid to prognostic clinical features, such as primary site and/or histological parameters including neuroendocrine marker profiles and mitotic indices. These may help to predict which patients will benefit from intensified treatment. In addition, further histological studies should address the identification of markers specific for lung- vs. extrapulmonary primary localization. For this purpose all available tumor tissue from our study is currently under histological re-analysis, assessing the expression of the novel tumor testis antigens.

A promising scope of modern scientific research is the use of autologous and allogeneic mesenchymal stem cells for regeneration of periodontal tissues. The aim of the study was to evaluate the nature of morphological changes in the pathologically altered periodontal tissues after injection of a biotransplant containing mesenchymal stem cells of the adipose tissue immobilized on a collagen carrier in an animal experiment. In the experiment, 60 randobbred females of white rats were used as a model, whose adipose tissue was taken to obtain allogenic mesenchymal stem cells. All animals were divided into 5 groups, depending on the planned method of treatment – 10 rats each. The control group consisted of 10 laboratory animals with healthy gingiva. The experimental gingival recession model was created by the V-shaped excision of periodontal tissues. The bioplastic collagen material “Collost” gel 7 % in isolated form determines the fibrosis intensification and serves as a “matrix” for the formation of a fibrous tissue, ensures the adhesion of stem cells and their transformation into pro- and fibroblasts. Injection of a cell transplant suspension into physiological saline activates the processes of cell proliferation and transformation of fibroblast differentiating cells. Suspension of the cell transplant on a sterile bioplastic collagen material “Collost” gel 7 % enhances the effects of gel and stem cells, promotes the leveling of atrophic and dystrophic changes in the gum, strengthening a mechanical component, reducing the recession of the gum and the depth of the gingival pocket.

Backgraund. Spleen surgery is mainly aimed to achieve effective hemostasis. The increasing popularity of topical hemostatic drugs is limited by their common side effect associated with the development of adhesions.The aim of study was to develop a new hemostatic drug with anti-adhesion activity. To achieve this, the authors have investigated 6% sodium carboxymethylcellulose gel with the addition of 5% aminocaproic acid. Materials and methods. The efficacy of the sample was studied experimentally in laboratory animals (rats, n = 87). The time of bleeding arrest, the amount of blood loss, the severity of the adhesion process, morphological and histological changes in tissues in the area of material implantation were assessed.Results. The study results evidenced that the new hemostatic drug reduced bleeding time by 68% (222.27 sec) and blood loss by 69% (285.6 mg) (p 0.01) after partial splenectomy, and prevented the development of adhesive process compared to the results obtained in the animals of the control group. On the 3rd day of the experiment application of the sample demonstrated that adhesions were completely absent, the coefficient of the severity of the adhesive process was 0 points; on the 7th and 14th days it was minimal - 0.481 and 0.486 points, respectively (p 0.05). A morphological study showed that the use of the new composite reduced the white pulp immunological reactivity associated with postoperative inflammatory processes, which is manifested by smaller lymphoid follicles and lower CD4 + T-lymphocytes expression.Conclusions. Thus, 6% sodium carboxymethylcellulose gel with the addition of 5% aminocaproic acid is an effective combined hemostatic and anti-adhesion agent that can be effectively applied in spleen surgery.

This study was conducted to determine the effects of diclofenac sodium in broiler chicks during the period from 20th July /2012 to 1st september/2012. The broiler chicks were divided into four groups A, B, C and control with ten day old bird in each. Group A was treated with @ 5mg/kg body weight, group B was treated with @ 10mg/kg body weight and Group C was treated with 20 mg/kg body weight given orally mixing with drinking water. Histopathological, hematological and biochemical tests were performed on 42th days of age to evaluate diclofenac-induced changes between control and treated groups. Mortality rate and pathomorphological changes were observed in dead birds. The acute toxicity was assessed by observing the clinical signs and symptoms, mortality, alterations in blood biochemistry, and necropsy findings. The birds of Group A showed only mild symptoms of diarrhea and 30% mortality. In Group B, 60% and Group 70% of birds died in between 24 and 36 h post-treatment showing the symptoms of segregatory behavior, lethargy, terminal anorexia, and severe bloody diarrhea. Observation of hematological parameters like TEC, Hb, PCV and ESR on 42th days of age showed significant (p<0.01) decrease in treatment group compare to control group. Observation of biochemical parameters (serum urea, serum creatinine) on 42th days of age showed significantly increased (p<0.01) serum urea and serum creatinine indicating nephrotoxicity in broilers. At 12 and 24 h post-treatment this returned to the normal levels. The dead birds of the high-dose group also showed similar pattern of biochemical changes at 12 and 24 h post-treatment and revealed extensive visceral gout with characteristic histopathological lesions in liver, kidney, heart, spleen and intestine on post-mortem. The results indicate that diclofenac sodium has hepatotoxic, nephrotoxic, and visceral gout inducing potentials in broilers (cob-500), especially at higher dose.DOI: http://dx.doi.org/10.3329/bjvm.v13i1.23710Bangl.

Abstract Background Malathion has been wildly used in agriculture and household pest control for years and can affect human health through drinking water and dietary exposure. This study was to investigate the immunotoxicity of malathion (MLT）on BALA/c mice for the purpose of providing a scientific basis for pesticides registration management of MLT and other pesticides. Methods Female mice were randomly divided into five groups. Both the negative control and the positive control groups of mice were daily gavage with corn oil, and those in the positive control group were intraperitoneal injected with 200 mg/kg bw of cyclophosphamide (CY) 24 h before the end of the study. In the dosage groups, MLT were daily gavage at doses of 16, 65 and 258 mg/kg bw for 30 days, respectively. After exposure, the body weight, the absolute and relative weight of organs, the hematology and clinical chemistry parameters, the splenocyte number, the bone marrow cell classification, histopathology, as well as the cellular immunity, humoral immunity, and non-specific immunity functions of mice were studied. Comparisons between multiple groups were carried out by using one-way ANOVA followed by Bonferroni post hoc comparisons tests when equal variances assumed and Dunnett’s T3 post hoc tests when equal variances assumption was not met.ResultsCompared with the negative control group, the low dose of MLT significantly reduced the levels of IL-10, neutrophil, polychromatic erythroblast and monocyte series (P<0.05)，induced atrophy in white pulp of spleen (1/10), which showed an immunosuppression in mice，and increased the absolute and relative weight of thymus (P<0.05). Inhibition of the PFC response, liver injury and thymus atrophy were observed in the high-dose group. What’s more, the IgG level was abnormally elevated with the increase of dose and presented a dose-response relation (P<0.05). ConclusionsThe immunotoxicity of low-dose of MLT is clear from the evidence and the LOAEL of MLT is preliminarily considered to be 16 mg/kg bw. It is much lower than that of the NOAEL (29 mg/kg bw) based on a 2-year chronic toxicity test and carcinogenicity test in rats, which was used to derive the ADI by Joint WHO/FAO Meeting on Pesticide Residues (0.3 mg/kg bw). It indicates that the immune system is a more sensitive target of MLT toxicity.

Background: The versatile and dynamic activities of Panax Ginseng are attributed to its active components. They are readily available over the counter and are known for their effects as an aphrodisiac & health building; in addition, they are given rather generously during pregnancy, as they are considered virtuous for the baby and mother. Despite its easy availability and excess usage, little is known about its effects on the fetus. The current experimental design was focused towards the lack of differentiation and inhibition of cell growth of mesodermal derivatives inflicted by PanaxGingex. Methods:18 pregnant albino dams were randomly divided into three groups; Group A was control, Group B was Low dose and Group C was labeled as High dose groups. Tissues (bone, kidney and blood) were selected as derivatives of paraxial, intermediate and lateral plate mesoderm respectively and were used for light microscopic study. Results and Conclusion: The light microscopic examination demonstrated extensive apoptosis and an escalation of angiogenesis. Both the histological findings were not only statistically significant but was clearly indicative of dysmorphogenesis. The results of present study raise a finger towards the unsupervised practice of over the counter preparations especially during the vital antenatal period of development.

An experiment was conducted to investigate the counteracting effects of spirulina in Long Evans rats exposed to oral potentiated sulfonamide administration. 20 rats were randomly assigned into four equal groups (A, B, C and D) and were fed with standard broiler pellet (25g/rat/day) throughout the experimental period of 60 days. Rats of Group A were fed only with pellet without any experimental diet and were defined as control. Rats  of Group B were treated with potentiated sulfonamide @ 96 mg/rat/day orally whereas Group C was treated with potentiated sulfonamide @ 96 mg/rat/day plus spirulina (Spirulina maxima) @ 50 mg/rat/day orally (low dose spirulina). In Group D, potentiated sulfonamide and spirulina (Spirulina maxima) were given through feed @ 96 mg/rat/day and @ 100 mg/rat/day (high dose spirulina) respectively. Hematological parameters (TEC, Hb and absolute count of lymphocyte, neutrophil and eosinophil) and hispathological profile of liver and kidney were recorded. The investigation revealed that the oral administration of sulfonamide significantly (p<0.01) decreased the TEC (5.93±0.24) value, number of lymphocyte (581.76±3.70) and neutrophil (581.76±3.70) compared to other treated groups and control group. On the other hand significant (p<0.01) increase (422.86±2.34) in eosinophil population has been found in rats fed on sulfonamide irrespective of spirulina supplementation on the final day of experiment compared to other treated group and control group. From this experiment it is evidenced that spirulina has a potential counteracting effect against sulfonamide. Histopathology of kidney and liver was done at the end of experiment (60 days) and no significant change was found except in the kidney of Group B and C.DOI: http://dx.doi.org/10.3329/bjvm.v10i1-2.15650

Abstract Autologous peripheral blood stem cell (PBSC)- supported high-dose melphalan (HDM) is now considered standard therapy in the treatment of multiple myeloma, at least for patients under 65 years. Oral mucositis is a frequent non-hematological complication which causes severe pain, interferes with patient nutrition and can lead to systemic infection. Amifostine (WR-2721; Ethyol), a phosphoaminothiol, is a prodrug that protects a broad range of normal tissues from the cytotoxic damage induced by anticancer agents. We retrospectively compared two groups of patients with stage II/III previously untreated multiple myeloma who received between April 96 and May 2004 an induction chemotherapy with 3 or 4 cycles of VAD (vincristine, adriamycin, dexamethasone) followed by HDM (200 mg/m²) and autologous PBSC transplantation. These two groups either received (group A, n = 10 ) or did not receive (group B, n= 32) amifostine (740 mg/m²) before HDM. The occurrence of grade 3/4 oral mucositis was significantly decreased in group A in comparison to group B (10% versus 53%, p =0.023) with no difference for the time to mucosal recovery. Supportive care differed between the two groups: only 2 patients (20%) needed opioid treatment in group A versus 22 patients (69%) in group B ( p=0.005) and 1 patient (10%) required parenteral nutrition in group A compared to 16 patients (50%) in group B (p= 0.015). The occurrence of severe infectious complications did not differ between the two groups (0% versus 12,5%, p= 0.56). Amifostine did not affect haematological recovery, the median time to granulocyte recovery to > 500/μl was similar in the two groups (8,4 days versus 9,9 days, p=0.22). Moreover, there is no statistically significant difference between the amifostine and control group for the disease response. The tolerability of amifostine was excellent and no adverse effects were reported. This study suggest that amifostine can reduce mucosal damage associated with high dose melphalan-based therapy, reducing, as a consequence, the necessity of nutrition and analgesic support, without compromising therapeutic benefit. Obviously, these interesting results have to be confirmed by larger randomised trials.

Information on the effects of phytoestrogens on animals has increased recently; however, there were only few studies on prenatal exposure on cellular immune response. Pregnant rats were assigned to 3 groups (12 rats per group), the first was fed control diet, the second was fed low-dose (6.5 g/100 g of diet) soy isoflavones, while the third was fed high-dose (26 g/100 g of diet) soy isoflavones. The female offspring cell-mediated immune response was determined using phytohemagglutinin (PHA) injection, and intumesce index was calculated on postnatal day 50. After 24 hours of PHA injection, blood samples were collected for tumor necrosis factor α, interferon γ (IFN-γ), and interleukin (IL)-12 determination. Spleen, thymus, and PHA-injected footpads were fixed for histopathology. Intumesce index was significantly ( P < 0.05) reduced in rats’ offspring born from dams fed low- and high-dietary soy isoflavones than that in control groups. Thymic relative weights in offspring of rats fed high-dietary soy isoflavones showed a significant ( P < 0.05) decrease compared to that in the control group. Female offspring where low and high-dietary soy isoflavones were fed to their dams showed a significant ( P < 0.05) decrease in IFN-γ and IL-12 than that in control ones. Spleen of rats born from dams fed high dose of dietary soy isoflavones showed lymphocytic depletion in white pulp. Taking together, it is clear that dietary soy isoflavones at prenatal period had immunosuppressive effect on female offspring after PHA stimulation. This effect was mediated through reduced IFN-γ that interplayed in IL-12 production pathway thus reducing its level.
