Abstract
Cornelian cherry (Cornus mas L.) fruits, abundant in iridoids and anthocyanins, are natural products with proven beneficial impacts on the functions of the cardiovascular system and the liver. This study aims to assess and compare whether and to what extent two different doses of resin-purified cornelian cherry extract (10 mg/kg b.w. or 50 mg/kg b.w.) applied in a cholesterol-rich diet rabbit model affect the levels of sterol regulatory element-binding protein 1c (SREBP-1c) and CCAAT/enhancer binding protein α (C/EBPα), and various liver X receptor-α (LXR-α), peroxisome proliferator-activated receptor-α (PPAR-α), and peroxisome proliferator-activated receptor-γ (PPAR-γ) target genes. Moreover, the aim is to evaluate the resistive index (RI) of common carotid arteries (CCAs) and aortas, and histopathological changes in CCAs. For this purpose, the levels of SREBP-1c, C/EBPα, ATP-binding cassette transporter A1 (ABCA1), ATP-binding cassette transporter G1 (ABCG1), fatty acid synthase (FAS), endothelial lipase (LIPG), carnitine palmitoyltransferase 1A (CPT1A), and adiponectin receptor 2 (AdipoR2) in liver tissue were measured. Also, the levels of lipoprotein lipase (LPL), visceral adipose tissue-derived serine protease inhibitor (Vaspin), and retinol-binding protein 4 (RBP4) in visceral adipose tissue were measured. The RI of CCAs and aortas, and histopathological changes in CCAs, were indicated. The oral administration of the cornelian cherry extract decreased the SREBP-1c and C/EBPα in both doses. The dose of 10 mg/kg b.w. increased ABCA1 and decreased FAS, CPT1A, and RBP4, and the dose of 50 mg/kg b.w. enhanced ABCG1 and AdipoR2. Mitigations in atheromatous changes in rabbits' CCAs were also observed. The obtained outcomes were compared to the results of our previous works. The beneficial results confirm that cornelian cherry fruit extract may constitute a potentially effective product in the prevention and treatment of obesity-related disorders.

Abstract
Introduction Testin is a protein involved in cell mobility, adhesion and colony formation. In rats, testin presence has been reported in the testes, and its possible role in spermatogenesis has been suggested. Studies in humans also suggest a possible role of testin as a cancer suppressor protein. In the dog, which represents both an important pet species and a good animal model for studying biological and pathological testicular processes, the presence of testin has never been reported. Material and Methods In the present study, the expression of testin in foetal, prepubertal, adult and aged canine testes was investigated. Testes from 5 adult and 3 aged dogs, from 2 one-month-old puppies and from 2 foetuses miscarried at the end of pregnancy were immunohistochemically examined with a commercial antibody against testin. Results Testin was intensely expressed in Sertoli cells in every testis examined. Spermatids were also positive for testin in mature dogs and in the testicular areas of the aged ones which were not atrophic. Weak expression of testin was also detected in all testes examined. Conclusion The present study, the first demonstrating the presence of testin in canine testes, provides the basis for further dog-human comparative research and for studies on the role of this protein in canine physiology, reproduction and testicular pathologies.

Abstract
Introduction The development of genetic research over recent decades has enabled the discovery of new genetic markers, such as single nucleotide polymorphisms (SNPs). This, as well as the full sequencing of the dog genome, has enabled genome-wide association studies (GWAS) to be used in the search for genetic causes of canine mammary tumours (CMTs). Material and Methods Genotypic data containing 175,000 SNPs, which had been obtained using the Illumina CanineHD BeadChip microarray technique, were available for analysis in this study. The data concerned 118 bitches, including 36 animals with CMT, representing various breeds and age groups. Statistical analysis was performed in two steps: quality control of genotyping data and genome-wide association analysis based on dominant, recessive, overdominant, codominant, and log-additive models with the single SNP effects. Results A total of 40 different SNPs significantly associated with CMT appearance were detected. Moreover, twelve SNPs showed statistical significance in more than one model. Of all the significant SNPs, two, namely BICF2G630136001 in the overdominant model and TIGRP2P107898_rs9044787 in the log-additive model, reached the 5-8 significance level. The other SNPs were significant to a 1-5 level. Conclusion In the group of SNPs indicated as significant in the GWAS analysis, several transpired to be localised within genes that may play an important role in CMT.

Abstract
BACKGROUND Testicular tumours are common in dogs and, among them, interstitial cell tumours, seminomas and sustentacular cell tumours are the most reported. Mesenchymal testicular tumours are rarely reported in humans as in veterinary medicine where only three cases of sarcomas (leiomyomas and leomyosarcomas) have been described in two stallions and in a ram. CASE PRESENTATION The present cases regarded a 12-year-old mixed-breed dog and a 10-year-old American Staffordshire Terrier that underwent bilateral orchiectomy. Formalin fixed testes were referred for histopathological diagnosis. At gross examination, in one of the testes of both dogs, a white, firm and variably cystic testicular mass, effacing and replacing the testicular parenchyma was detected. Samples were collected from both neoplastic and contralateral testes, routinely processed for histology and serial sections were also examined immunohistochemically with primary antibodies against cytokeratins, vimentin, Von Willebrand factor, inhibin-α, α-smooth muscle actin, smooth muscle myosin and desmin. Histopathological features as well as the immunohistochemical results, positive for vimentin, actin, myosin and desmin, confirmed the mesenchymal origin and the myoid phenotype of both testicular tumours supporting the diagnoses of leiomyosarcoma. CONCLUSIONS To the authors knowledge these are the first cases of primary testicular sarcoma reported in the canine species. However, even rare, these tumours deserve to be considered in routine diagnosis when a testicular spindle cell tumour is observed. The immunohistochemical panel applied was useful to distinguish the present tumours from undifferentiated Sertoli cell tumours confirming the diagnosis of leiomyosarcoma.

Abstract
All the surgical approaches described to date for the removal of distal urethral tumors have some technical difficulties that make these tumors difficult to treat. The article presents for the first time the treatment results of three female dogs, diagnosed with transitional cell carcinomas of the distal urethra, operated with a newly developed hybrid surgical method—a combination of laparoscopy and open surgery. This technique uses vulvovaginectomy, combined with resection of the distal urethra and prepubic urethrostomy. All of the procedures were possible to perform, without the need to carry out a laparotomy conversion. Histopathology revealed transitional cell carcinoma in all cases, with a margin of healthy tissues maintained in two out of three cases, which meant reoperation of the urethrostomy site in the remaining one case. The mean survival time was nine months. Among minor complications, recurrent cystitis was found. After the first surgery, all dogs retained full control over urination immediately after recovery from anesthesia. In one case that required reoperation, complete urinary incontinence occurred after the second procedure. The present findings suggest that hybrid surgery can be used to treat distal urethral tumors. Qualification for surgery must be limited to bitches with tumors of the distal urethra and without metastases, without the possibility of using other surgical methods, and with the owner’s full acceptance of the risk of complications.

Abstract
Background and Purpose Due to the risk of gastrointestinal damage and various tissue toxicity associated with non-steroidal anti-inflammatory drugs (NSAIDs) use, investigating new anti-inflammatory agents with efficacy comparable to that of NSAIDs but reduced toxicity is still a major challenge and a clinical need. Based on our previous study, new 1,3,4-oxadiazole derivatives of pyrrolo[3,4-d]pyridazinone, especially 6-butyl-3,5,7-trimethyl-1-[[4-[[4-(4-nitrophenyl)piperazin-1-yl]methyl]-5-thioxo-1,3,4-oxadiazol-2-yl]methoxy]pyrrolo[3,4-d]pyridazin-4-one and 6-butyl-1-[[4-[[4-(4-chlorophenyl)-4-hydroxy-1-piperidyl]methyl]-2-thioxo-1,3,4-oxadiazol-5-yl]methoxy]-3,5,7-trimethyl-pyrrolo[3,4-d]pyridazin-4-one (hereafter referred to as the compounds 10b and 13b, respectively) seem to be promising anti-inflammatory agents. This study aimed to elucidate the effects of these two new derivatives on the course of experimental rat inflammation, liver and kidney function, and gastric mucosa. Methods The anti-inflammatory effect of compounds 10b and 13b was evaluated using the carrageenan-induced paw edema test in rats. The increase in paw volume (paw edema), prostaglandin E2 (PGE2), tumor necrosis factor-α (TNF-α) and myeloperoxidase (MPO) levels, histological alterations, and inflammatory cell infiltration in paw tissue were determined. Serum alanine transaminase (ALT) and aspartate transaminase (AST) activities, serum urea and creatinine levels, as well as changes in gastric mucosa, were measured as indicators of hepatic, renal, and gastric toxicity. Results Pretreatment with both novel derivatives at 10 mg/kg and 20 mg/kg doses reduced paw edema, counteracted the increased PGE2 and TNF-α levels, reduced the influx of inflammatory cells, and decreased histopathological alterations in paw tissue. Compound 13b at a dose of 20 mg/kg was more effective than indomethacin in reversing the increased TNF-α levels and reducing the influx of inflammatory cells. Only compound 13b at all studied doses (5, 10, or 20 mg/kg) counteracted the increased MPO level in paw tissue. Both compounds neither caused alterations in ALT, AST, urea, creatinine parameters nor gastric mucosal lesions. Conclusion New compounds exert an anti-inflammatory effect, presumably via inhibiting inflammatory mediators release and inflammatory cell infiltration. Moreover, both possess a more favorable benefit–risk profile than indomethacin, especially compound 13b.

Abstract
Background This paper presents the first described case of laparoscopy-assisted prepubic urethrostomy and laparoscopic resection of a tumor of the distal part of the urethra in a female dog as a palliative treatment. Case presentation An intact, 11 -year-old, mixed breed female dog,
weighing 15 kg, was admitted with signs of urinary obstruction and difficulty
with catheterization. Vaginal, rectal, and endoscopic examinations revealed a firm
mass in the pelvic cavity at the level of the pelvic urethra. Ultrasound and
computed tomography examination showed enlargement of the urethral wall (5.5 cm
width and 3 cm thick), which was significantly restricting the patency of the
urethra. The lesion affected only the distal part of the urethra without the
presence of local or distant metastatic changes. The affected portion of the urethra was laparoscopically removed while performing pre-pubic urethrostomy with laparoscopy. The patient regained full consciousness immediately after the end of anesthesia, without signs of urinary incontinence. Histopathological examination of the removed urethra revealed an oncological margin only from the side of the bladder. In the period of 2.5 months after the procedure, the owner did not notice any symptoms that could indicate a postoperative recurrence, which was diagnosed three months after the procedure. Conclusions Pre-pubic urethrostomy can be successfully performed with the assistance of laparoscopy. The use of minimally invasive surgery will allow, in selected cases, removal of the urethral tumor, and in inoperable cases, to perform a minimally invasive palliative pre-pubic urethrostomy.

We evaluated the effect of the transgenic flaxseed W86-which is rich in ALA-on the lipid profile, atherosclerosis progression, and vascular reactivity in hypercholesterolemic rabbits compared to the parental cultivar Linola with a very low ALA content. Rabbits were fed a basal diet (control) or a basal diet supplemented with 1% cholesterol, 1% cholesterol and 10% flaxseed W86, or 1% cholesterol and 10% Linola flaxseed. A high-cholesterol diet resulted in an elevated plasma cholesterol and triglyceride levels compared to the control animals. Aortic sections from rabbits fed Linola had lower deposits of foamy cells than those from rabbits fed W86. A potassium-induced and phenylephrine-induced contractile response was enhanced by a high-cholesterol diet and not influenced by the W86 or Linola flaxseed. Pretreatment of the aortic rings with nitro-L-arginine methyl ester resulted in a concentration-dependent tendency to increase the reaction amplitude in the control and high-cholesterol diet groups but not the flaxseed groups. Linola flaxseed with a low ALA content more effectively reduced the atherosclerosis progression compared with the W86 flaxseed with a high concentration of stable ALA. Aorta contractility studies suggested that flaxseed ameliorated an increased contractility in hypercholesterolemia but had little or no impact on NO synthesis in the vascular wall.

Abstract
Clinical signs of prostatic diseases in dogs are often non-specific. Appropriate treatment should be based on a detailed investigation using reliable diagnostic tools. The aim of our study was to evaluate the diagnostic value of ultrasonography (US) and fine-needle aspiration (FNA) cytology in dogs' prostate diseases. The mean accuracy of FNA cytology and US were 0.72 and 0.88 (n = 13), respectively. US gland size measurements and actual gland dimensions were highly concordant. Obtained results confirm the high diagnostic value of US and FNA biopsy and in prostatic diseases. Diagnosis based on US is highly reliable; however, it should be combined with clinical signs. Therefore, cytological evaluation of prostate gland material may be performed to differentiate or confirm presumptive diagnosis.

Abstract
BACKGROUND Cornelian cherry (Cornus mas L.) is a plant growing in southeast Europe, in the past used in folk medicine. There are many previous publications showing the preventive effects of (poly)phenolic compounds, especially anthocyanins, on cardiovascular diseases, but there is a lack of studies comparing the effects of (poly)phenolics and other constituents of fruits. OBJECTIVES We have attempted to determine if iridoids and anthocyanins from cornelian cherry fruits may affect the formation of atherosclerotic plaques in the aorta as well as lipid peroxidation and oxidative stress in the livers of cholesterol-fed rabbits. MATERIAL AND METHODS Fractions of iridoids and anthocyanins were analyzed using the high-performance liquid chromatography (HPLC) and liquid chromatography-mass spectrometry (LC-MS) methods. Loganic acid (20 mg/kg b.w.) and a mixture of anthocyanins (10 mg/kg b.w.) were administered orally for 60 days to rabbits fed with 1% cholesterol. Histopathological samples of the aortas and the livers were stained with hematoxylin and eosin. Lipid peroxidation (malondialdehyde - MDA) and redox status (glutathione - GSH, glutathione peroxidase - Gpx and superoxide dismutase - SOD) were analyzed using spectrophotometrical methods. RESULTS Both loganic acid (an iridoid) and a mixture of anthocyanins diminished the formation of atherosclerotic plaques in the aorta. Both substances also diminished lipid peroxidation, measured as a decrease of MDA, and attenuated oxidative stress, measured as an increase of GSH in the livers depleted by cholesterol feeding. Unexpectedly, cholesterol feeding decreased the Gpx activity in the liver, which was reversed by both investigated substances. CONCLUSIONS We have shown that both iridoids and anthocyanins help prevent fed-induced atherosclerosis, and the consumption of fruits rich in these substances may elicit beneficial effects on the cardiovascular system.

Abstract
Low vitamin D status is considered as a risk factor for breast cancer and has prognostic significance. Furthermore, vitamin D deficiency increases after adjuvant cancer therapy, which alters bone metabolism increasing the risk of osteoporosis. It is now postulated that vitamin D supplementation in breast cancer treatment delays the recurrence of cancer thereby extending survival. We evaluated the impact of calcitriol and its low-calcemic analogs, PRI-2191 and PRI-2205, on the tumor growth, angiogenesis, and metastasis of 4T1 mouse mammary gland cancer. Gene expression analysis related to cancer invasion/metastasis, real-time PCR, ELISA, western blotting, and histochemical studies were performed. In vitro studies were conducted to compare the effects of calcitriol and its analogs on 4T1 and 67NR cell proliferation and expression of selected proteins. Calcitriol and its analogs increased lung metastasis without influencing the growth of primary tumor. The levels of plasma 17β-estradiol and transforming growth factor β (TGFβ) were found to be elevated after treatment. Moreover, the results showed that tumor blood perfusion improved and osteopontin (OPN) levels increased, whereas vascular endothelial growth factor (VEGF) and TGFβ levels decreased in tumors from treated mice. All the studied treatments resulted in increased collagen content in the tumor tissue in the early step of tumor progression, and calcitriol caused an increase in collagen content in lung tissue. In addition, in vitro proliferation of 4T1 tumor cells was not found to be affected by calcitriol or its analogs in contrast to non-metastatic 67NR cells. Calcitriol and its analogs enhanced the metastatic potential of 4T1 mouse mammary gland cancer by inducing the secretion of OPN probably via host cells. In addition, OPN tumor overexpression prevailed over the decreasing tumor TGFβ level and blood vessel normalization via tumor VEGF deprivation induced by calcitriol and its analogs. Moreover, the increased plasma TGFβ and 17β-estradiol levels contributed to the facilitation of metastatic process.

Abstract
AIM OF THE STUDY The attempt to limit the negative effects of polyester implants on the articular cavity by using preparations containing growth factors. MATERIALS AND METHODS Polyester implants used for the reconstruction of a rabbit's cranial cruciate ligament (CCL) were saturated with autogenic platelet-rich plasma (PRP), antlerogenic stem cells MIC-1 and their homogenate prior to the surgery. Six months after CCL reconstruction, morphological, and biochemical blood tests were carried out, including proteinogram and acute phase proteins. The knee joints were also examined macro- and microscopically. RESULTS The results, compared to the control group, showed a favorable effect of the PRP and homogenate of antlerogenic cells on limiting the inflammation caused by the presence of polyester implant in the knee joint. The addition of growth factors caused covering the implant faster with the recipient's connective tissue, thus contributing to reducing the inflammatory reaction of the articular capsule to the presence of polyester. At the same time, no enhanced local or general reaction of the rabbit organism was observed to the presence of xenogenic antlerogenic stem cells MIC-1 homogenate which, like the PRP, may provide an easily available source of growth factors, increasingly often used in regenerative medicine. CONCLUSIONS Applying antlerogenic stem cells, their homogenate or PRP increases the volume of connective tissue that surrounds and intertwines polyester CCL implant, separating it from synovial cavity environment.

Abstract
An 18-month-old European shorthair cat was subjected to genetic studies due to ambiguous external genitalia (underdeveloped both penis and scrotum). Further anatomic and histopathological studies revealed the presence of abdominal, atrophic testes and uterus. Cytogenetic analysis showed two cell lines, one with X monosomy-37,X [90% of the analysed metaphase spreads], and other line had 38 chromosomes with normal X chromosome and abnormally small Y-derived chromosome-38,X,der(Y) [10%]. Further fluorescence in situ hybridization study with telomeric probe revealed a ring structure of the der(Y). Eight Y chromosome-specific genes, SRY, TETY1, TETY2, CUL4BY, CYORF15, HSFY, FLJ36031Y and ZFY, were detected. We conclude that the described abnormality of the reproductive system, leading to sterility, was caused by a very rare type of chromosomal mosaicism-37,X/38,X,r(Y).

Abstract
Abstract
Lymphocytic infiltrations located in the extracellular matrix often accompany canine skin cancer. They can be characterised as an inflammatory infiltration and/or a second tumour - lymphoma. The aim of this study was an immunohistochemical analysis of a lymphocytic infiltration which accompanies spontaneous skin cancer. Twenty basal cell carcinoma, 20 non-keratinizing squamous cell carcinoma, 20 keratinizing squamous cell carcinoma and 8 sebaceous gland carcinoma samples which were accompanied by a lymphocytic infiltration and/or secondary lymphatic follicles were verified histopathologically. The expression of bcl-2, CD3, CD79α, Ki-67, MCM-3 and MCM-7 in the lymphocytic infiltration was evaluated. Four types of lymphocytic infiltrations were found: I - diffuse bcl-2+, II - diffuse bcl-2-, III - follicular bcl-2+/- where the centre was bcl-2-, and the marginal zone of the follicles and the extrafollicular area were bcl-2+ and IV - aggregated bcl-2+, where the centre and periphery were bcl-2+. The I and IV type corresponds to lymphoma, II type is non-neoplastic immune response and III type suggest reactive follicular hyperplasia. The proliferation of lymphocytes which demonstrated the expression of neoplastic markers (I and IV), suggests preneoplastic phase (pseudolymphoma) or lymphoma - the second independent tumour. A high proliferative index of the follicular blc-2+/- follicular infiltration indicates an increased immunological response of the host against skin cancer.

Abstract
Disorders of sex development (DSD) are rare in cats. They can be caused by chromosomal aberrations, gene mutations or other undefined factors. The aim of the present study was to compare the histological structure and immunohistochemical reactivity of testes in cats with DSD and in healthy cats. The research material consisted of the gonads of four cats - phenotypic males with an incorrect structure of the reproductive system. The control group consisted of the testes of four healthy cats - routinely castrated phenotypical males. The material was fixed with formalin and embedded in paraffin; the sections were stained with hematoxylin and eosin. The immunohistochemical investigation were performed using monoclonal and polyclonal antibodies directed against desmin, vimentin, actin of smooth muscles, S100 protein and MCM3 protein. The results obtained allow concluding that the testes of cats with DSD differed in certain respects, mainly in the number of blood vessels, from the normal testes. Moreover, the results of immunohistochemical examination indicate that in the testes of cats with DSD the number of supporting cells is lower, the amount of interstitial cells is comparable and spermatogenesis is correct es compared to those determined in the control gonads. The number of blood vessels in cats with DSD is reduced by about 30%. It confirms the recommendations for castration of these animals in order to eliminate the potential inheritance of sex development disorders.

Abstract
The aim of the study was to analyze the frequency and location of tumors in domestic as well as exotic animals in Lower Silesia. The research material consisted of 4174 cases of malignancies from dogs, cats, horses and exotic animals taken at the time of surgery or biopsy sections. The largest group consisted of tumors of dogs – 3519 cases (84.31%), followed by cat – 498 cases (11.93%), ferrets – 27 cases (0.65%), rats – 24 cases (0.57%), horses – 12 cases (0.28%), rabbits – 21 cases (0.5%), guinea pigs, 21 (0.5%). The average annual number of tests performed (2087 cases per year) may suggest an increased awareness of the need for veterinarians’ testing for histopathology, whose purpose is to determine the prognosis of their patients, as well as the further proceedings. Tumors were divided into 6 histological types. The largest group were malignant epithelial and mesenchymal. It can be concluded that in domestic animals cancer most often occurs in carnivores, 60% of the cases considered as malignant tumors, and 40% benign (dogs), and correspondingly in cats (76% and 24%) equally in both sexes in dogs and 20% prevalence of disease in male cats. In contrast, among the 146 reported cases referred to by us as exotic, cancer accounted for 59.6% and 40.4% benign.

Abstract
We established a new B-cell leukaemia cell line CLB70 from a dog with chronic lymphocytic leukaemia. This cell line is positive for CD20, CD45, CD79a, MHC class II, IgG, IgM; weakly positive for CD21; and negative for CD3, CD4, CD5, CD8, CD14, CD34, CD117. PCR for antigen receptor gene rearrangement (PARR) analysis revealed a biclonal immunoglobulin heavy chain (IgH) gene rearrangement and negative result for TCRγ. Western blot analysis of anti- and pro-apoptotic proteins showed increased expression of Bcl-2, Mcl-1, NF-kB, and Ras, and decreased expression of p53. CLB70 cells grow rapidly in vitro and are tumourigenic in nude mice. The CLB70 line is highly sensitive to doxorubicin, less sensitive to etoposide and imatinib, and resistant to piroxicam, celecoxib and dexamethasone. Our results indicate that CLB70 cells are derived from mature B-cells and they may be a useful tool for the development of new therapeutic strategies for both dogs and humans.

Abstract
The study aimed at immunohistochemical analysis of various markers of cell proliferation and comparison of the results with canine mast cell tumours grading systems according to the Patnaik and Kiupel. Tissue sections were stained using classical technique with haematoxylin and eosin, and immunohistochemical studies were performed with Ki-67, PCNA and MCM-3 antibodies. Additionally the mitotic index was assessed. Statistical analysis including rank correlation Spearman's and ANOVA Friedman analysis was performed. The significance was set at p<0.05. Expression of all examined antigens was detected. The results obtained allow concluding that there is a strong relationship between all the cell markers. However, due to the very strong response and positive reaction in the majority of tumours PCNA is not recommended as a prognostic indicator. Ki-67 and MCM-3 can be successfully used in the evaluation of canine mast cell tumours.

Abstract
Abstract
The aim of the study was to assess the microvessel density based on the analysis of the expression of the CD31, VEGF, and LIMS-1 proteins in canine mast cell tumours. The study was conducted on 60 mastocytomas; 16 cases were classified as the grade I, 26 as the grade II, and 18 as the grade III. Statistical analysis showed a positive correlation only between the grade of the tumour and the expression of LIMS-1. In conclusion, LIMS-1 could be successfully used as a prognostic endothelial cell marker in mast cell tumour. CD31 may be a useful marker, but further examinations are necessary. VEGF is not recommended

Abstract
The diagnosis of hibernoma is uncommon in veterinary medicine. In this report, we present an attempt to confirm hibernoma diagnosed in dogs by applying immunohistochemical tests routinely used in human pathology i.e. antibodies specific to protein S100, protein CD31, or smooth muscle actin (SMA).

Abstract
Morphological and immunohistochemical analysis of 45 canine mast cell tumours was performed to determine whether the proteins examined are useful for a more precise description of tumour morphology and a more reliable determination of the prognosis in patients. Tissue sections were stained according to the standard haematoxylin and eosin (HE) technique and with toluidine blue to demonstrate cytoplasmic granules. Immunohistochemical studies were performed, using the cell markers CD117 (c-kit), p16 and von Willebrand factor (FVIII). In CD117 three different staining patterns were observed: (1) membranous reaction, (2) intense staining of cytoplasm, and (3) a diffuse, delicate cytoplasmic reaction. Von Willebrand antibody was evaluated on the basis of the number of blood vessels stained. p16 expression was evaluated by scoring positive nuclear reaction. Positive expression was demonstrated for all examined antigens, but their level of expression differed depending on the grades of tumour malignancy. Statistical analysis of the results documented a pronounced positive correlation between the markers studied and the grade of tumour malignancy (P < 0.001). It was shown that each of the cell markers examined represents a useful prognostic indicator for patients with mast cell tumours. The calculated correlation coefficients demonstrate a strong association between the expressions of CD117, FVIII and p16, and the histological malignancy of a tumour.

Abstract
An infertile Siamese female cat was subjected for clinical, histological, cytogenetic and molecular studies due to ambiguous external genitalia (vulva, vagina, rudimentary penis and scrotum-like structure) and masculine behaviour. An elevated oestrogen activity and a detectable level of testosterone were found. The cat underwent laparotomy. The gonads and the uterus were removed and subjected for histological studies, which showed ovaries with corpora lutea and a some primordial follicles. Chromosome studies of lymphocyte and fibroblast cultures, with the use of Giemsa staining, G-banding and whole X chromosome painting by fluorescence in situ hybridization, revealed pure X monosomy. Molecular analysis showed the absence of the SRY gene. Our study revealed for the first time that X monosomy in cats may be associated with virilization, in spite of the lack of the SRY gene.

Abstract
Cornelian cherry (Cornus mas L.) fruits have been used in traditional cuisine and in folk medicine in various countries. This study was conducted to evaluate the constituents and impact of cornelian cherry (C. mas L.) fruits lyophilisate on lipid levels, PPARα protein expression, atheromatous changes in the aorta, oxido-redox state, and proinflammatory cytokines in hypercholesterolemic rabbits. The HPLC-MS method was used for determining active constituents in cornelian cherry. In a subsequent in vivo study the protective effect of the cornelian cherry on diet-induced hyperlipidemia was studied using a rabbit model fed 1% cholesterol. Cornelian cherry (100mg/kg b.w.) or simvastatin (5mg/kg b.w.) were administered orally for 60 days. Two iridoids - loganic acid and cornuside - and five anthocyanins were identified as the main constituents of the cornelian cherry. The administering of the cornelian cherry led to a 44% significant decrease in serum triglyceride levels, as well as prevented development of atheromatous changes in the thoracic aorta. Cornelian cherry significantly increased PPARα protein expression in the liver, indicating that its hypolipidemic effect may stem from enhanced fatty acid catabolism. Simvastatin treatment did not affect PPAR-α expression. Moreover, the cornelian cherry had a significant protective effect on diet-induced oxidative stress in the liver, as well as restored upregulated proinflammatory cytokines serum levels. In conclusion, we have shown loganic acid to be the main iridoid constituent in the European cultivar of the cornelian cherry, and proven that the cornelian cherry could have protective effects on diet-induced hypertriglicerydemia and atherosclerosis through enhanced PPARα protein expression and via regulating oxidative stress and inflammation.

Abstract
Lymphoma is the most frequently diagnosed cancer of the canine haematopoietic system. In this study, the flow cytometry and polymerase chain reaction (PCR) analysis were used to characterize a series of canine lymphomas in detail. The aim of this study was to determine the incidence of B- and T-cell high-grade lymphomas and their immunophenotypic characterization in Lower Silesia, Poland. The results show that the frequency of each type of lymphoma is 71% for B-cell and 17% for T-cell lymphomas. In two cases the PCR techniques confirmed the presence of simultaneous double gene rearrangements of the BCR and TCR receptors.

Abstract
A disorder of sexual development (DSD) of dogs with a female karyotype, missing SRY gene, and presence of testicles or ovotestes is quite commonly diagnosed. It is suggested that this disorder is caused by an autosomal recessive mutation; however, other models of inheritance have not been definitely ruled out. In an earlier study it was hypothesized that the mutation may reside in a pericentromeric region of canine chromosome 23 (CFA23). Three positional candidate genes (CLASP2, UBP1, and FBXL2) were selected in silico in the search for polymorphisms in 7 testicular or ovotesticular XX DSD dogs, 8 XX DSD dogs of unknown cause (SRY-negative, with enlarged clitoris and unknown histology of gonads), and 29 normal female dogs as a control group. Among the 15 molecularly studied dogs with enlarged clitoris there were 3 new cases of testicular or ovotesticular XX DSD and 4 new cases of XX DSD with unknown cause (histology of the gonads unknown). Altogether, 11 (including 10 novel) polymorphisms in 5'- and 3'-flanking regions of the studied genes were found. The distribution analysis of these polymorphisms showed no association with the DSD phenotypes. Thus, it was concluded that the presence of the causative mutation for testicular or ovotesticular XX DSD in the pericentromeric region of CFA23 is unlikely.

Abstract
1. Acetylsalicylic acid (ASA) and sodium salicylate (SS) are considered safe for poultry and often used in avian medicine. However, information on tolerance and specific side effects of these drugs in birds is lacking. 2. The aim of this study was to determine the effects of 14 d administration of high doses (200 or 400 mg/kg) of either ASA or SS on body weight gain, blood biochemistry, white and red blood cell counts and pathology in broilers. In addition, minimal plasma salicylate concentrations were determined on the 1st, 5th, 10th and 14th d of treatment. 3. The results showed that the dose of 400 mg/kg of either ASA or SS decreased weight gain and induced gizzard ulceration. Kidney to body weight ratio was increased in a dose-dependent manner, but serum concentrations of creatinine and uric acid were not affected. A time-dependent decrease in the minimal plasma salicylate concentration was evident.

Abstract
Telomerase activity could be a potential marker for the neoplastic process, because it is absent in normal cells and present in tumor cells. Immunohistochemical studies were conducted using samples obtained from 32 uterine myomas, each sample having a size of 3-4 cm and obtained from women between 35 and 45 years of age. These studies also concentrated on fragments of macroscopically unaltered myometrium, collected 3-4 cm from a uterine tumor. Immunohistochemistry was performed using antibody to the catalytic unit of telomerase (hTERT; clone 44F12, NCL-L-hTERT, Novocastra Laboratories, UK). This study aimed at detecting a possible presence of potentially neoplastic cells in the margins of healthy tissue, which was removed together with the primary tumor. The results were classified according to the number of telomerase-positive cells. Tumors of the first group had up to 50% telomerase-positive cells, while their content in the second group exceeded 50%. Our study demonstrated an almost two-fold increase in the number of telomerase-positive tumor cells compared with myometrial cells 3-4 cm from the tumor. Hopefully, investigating the presence of telomerase in both uterine myometrium and myoma could facilitate the diagnosis of the neoplastic process.

Abstract
Nucleolar organizer regions (NORs) were assessed in 27 women affected by uterine leiomyoma. Tissue samples obtained during surgery were silver-stained according to the method of Ploton et al. The assessed parameters were as follows: the number of argyrophylic nucleolar organizer regions (AgNORs) per nucleus, single AgNOR area, AgNOR intranuclear distribution, and AgNOR coefficient. The parameters were assessed quantitatively. It was found that the AgNOR coefficient was higher in uterine leiomyoma compared to the normal smooth muscle cells. The development of leiomyoma is associated with a marked decrease in myocyte nucleolar area, which accounts for 30% of the nucleus in the normal myometrium. With the comparable AgNOR number in the single nucleus, there were no differences in the single AgNOR granule area (1.21 microm2 +/- 0.047 and 1.11 microm2 +/- 0.025 in normal myometrium and in leiomyoma, respectively). In the normal myometrium, there was a positive correlation between nuclear area and the single AgNOR granule area, as well as between the AgNOR coefficient and the single AgNOR granule area. There was also a negative correlation between the number of granules per nucleus and their central and peripheral intranuclear distribution. The development of leiomyoma was associated with loss of all correlations observed in the control group.

Abstract
The molecular background of the most frequent intersexuality syndrome in dogs (female-to-male sex reversal with the female karyotype and a lack of the SRY gene) is unknown. In this article, new cases of this syndrome are described in two unrelated American Staffordshire terrier dogs and one miniature pinscher dog subjected to cytogenetic and molecular analysis due to the presence of an enlarged clitoris. One dog was operated on and histological studies of the gonads revealed a testicular structure without signs of spermatogenesis, but the uterus wall appeared to be normal. All three dogs had female chromosome complements and lacked the Y-linked genes SRY and ZFY. Eight fragments, representing the vast majority of the coding sequence of the SOX9 gene, and two fragments of the 5' flanking region of this gene were analyzed. The studied fragments had identical DNA sequences when comparing the intersexual dogs with GenBank sequences (AY237827; NW139883). Thus a mutation in the coding sequence as well as the promoter region of the SOX9 gene might be excluded as a cause of this type of intersexuality. The importance of further studies of the 5' flanking region of this gene is discussed.

Abstract
Behaviour of argyrophilic nucleolus organising regions (AgNOR) was estimated in various types of spontaneous and transplantable tumors in animals. The studies were performed on spontaneous epithelial and mesenchymal tumors, malignant and non-malignant, as well as transplantable tumors: Morris hepatoma, mammary gland carcinoma and Yoshid sarcoma. The examinations were made on paraffin sections, using silver-staining method according to Ploton et al. Quantitative assessment was made with computer-aided microscopic image analysis system Multi-Scan Base V.8 for Windows, coupled with Carl Zeiss microscope. It was demonstrated that AgNOR index reflects malignancy of the tumor, since it increases clearly in cancers and sarcomas, both spontaneous and transplantable. The highest AgNOR index--0.13--was noted in the group of spontaneous tumors in epithelial malignant tumors, and in the group of transplantable tumors in mesenchymal tumors (Yoshid sarcoma) it was 0.15. Classification of the studied spontaneous and transplantable tumors into groups of the same histogenesis, though phenotypically different, was aimed at demonstration of the increasing tendency of AgNOR index.

Abstract
The results of several experimental and epidemiological studies have shown an inverse correlation between Mg status and the risk of some cancers. However, relationship between magnesium and cancer is complex. The aim of our work was to examine the precise effect of Mg deficiency on transplantable mouse tumor growth and metastasis. The results obtained indicate a significant retardation of primary tumor growth (up to 70%) in mice receiving Mg-deficient diet. However, Mg repletion caused in these mice significant increase of primary tumor burden. Analysis of cell cycle distribution showed a reduced percentage of cells in the S phase and an increase of cells in the G(0)/G(1) phase of the cell cycle in LLC tumors caused by Mg deficiency. This is in agreement with the effect of low Mg level on cell growth observed in vitro. Interestingly, in mice inoculated with LLC cells and receiving low-magnesium diet, a higher metastatic potential was observed as compared to control mice. In conclusion, our results demonstrate a direct role of magnesium in tumor growth and also point at deleterious effect of low magnesium status on tumor metastasis.

Abstract
It has been well documented that experimental hypomagnesemia in rodents evokes, as an early consequence, an inflammatory response. This also leads to the activation of cells producing reactive species of oxygen and, as a result, to the oxidative damage of tissues. Several studies have shown that lungs might be a specific target of Mg deficiency. Here, we report that 3 weeks of Mg deficiency in mice resulted in inflammatory processes in the lungs, including interstitial and perivascular pneumonia, manifested by the infiltration of leukocytes, plasmocytes and histiocytes, as well as the phenomenon of disseminated intravascular coagulation (DIC). These phenomena were accompanied by changes in gene expression assessed by cDNA array. In this study we identified 26 genes significantly changed by Mg deficiency, mostly involved in the anti-oxidative response, regulation of cell cycle and growth, apoptosis as well as cell-cell and cell-matrix interactions. We conclude that these changes are related to the phenomena of inflammatory and oxidative processes and consecutive remodeling occurring in the tissues as a result of Mg deficiency. This may have implications for at least several lung pathologies, including allergies, asthma, SIDS (Sudden Infant Death Syndrome) or facilitate formation of lung metastases.

Abstract
Among the many potential antiangiogenic agents now in various stages of preclinical or clinical study, genistein (GEN) has generated wide interest being because of its natural origin (soybeans) and epidemiological studies showing the cancer chemopreventive effects of soybean consumption. In this paper the in vivo effects of GEN applied either alone or together with cyclophosphamide on the growth of mouse transplantable mammary carcinoma (16/C) transplanted either orthotopically or ectopically is presented. The growth of 16/C mouse mammary cancer transplanted subcutaneously (s.c.) or into the mammary gland (orthotopically-orth.) was stimulated by GEN administered from day 4 after tumor cell inoculation. Such stimulation was not observed when the treatment with GEN was started at day 12 after cell inoculation. Stimulation of tumor growth by GEN was markedly higher in mice transplantedorth. than in those transplanted s.c.. However, GEN did not affect the expression of estrogen (ER)and progesterone receptors (PgR) in the orthotopic model of 16/C cancer. In the case of subcutaneously growing tumors, treatment with GEN lowered (2-fold) the expression of both ER and PgR. In the interpretation of these results, the pleiotropic (including hormonal and antiproliferative), sometimes opposing effects of genistein in vivo should be considered. It seems rather reasonable to exclude breast and, perhaps, other hormone-dependent cancers from the treatment and chemoprevention with soy-derived phytoestrogens until its mechanism(s) of action on various cancer cells is completely understood.

Abstract
Many efforts have been made to obtain active and less toxic Vitamin D analogs for new clinical applications. The results of previous studies demonstrated the efficacy and safety of topical treatment of psoriasis with one of these analogs, 1,24-dihydroxyvitamin D(3), tacalcitol (1,24-(OH)(2)D(3)). In the present study, we evaluated the toxicity and antitumor effect of this analog. Lethal toxicity of 1,24-(OH)(2)D(3) after s.c. injection was significantly lower than that of calcitriol. No significant differences were observed in the toxicity of the analogs when administered p.o. Calcium levels in the serum of mice treated with calcitriol were significantly higher (111%) than those in mice treated with 1,24-(OH)(2)D(3) (89%) at 5 day after the first s.c. (10 microg/kg/day) administration in comparison to the control (healthy, untreated animals). Oral administration increased the calcium level by 78% for calcitriol and only to 47% over the control for 1,24-(OH)(2)D(3). Parallel administration of clodronate prevented the calcitriol- and 1,24-(OH)(2)D(3)-induced lethal toxicity and also prevented increase in calcium levels. Single therapy with calcitriol did not affect tumor growth in the 16/C mouse mammary cancer model. In contrary, 1,24-(OH)(2)D(3) alone reduced tumor volume to 41% of control. Cisplatin alone did not affect growth of 16/C tumor in these conditions. The growth of tumors in the presence of cisplatin was inhibited by 1,24-(OH)(2)D(3) but not by calcitriol. Interestingly, the inhibition of tumor growth in cisplatin-treated mice by 1,24-(OH)(2)D(3) was greater, than that observed in mice treated with this analog alone. In conclusion, 1,24-(OH)(2)D(3) revealed higher antitumor and lower calcemic activity and toxicity than calcitriol. Application of biphosphonates along with Vitamin D analogs is sufficient to overcome the calcemic and toxic side effects of the proposed treatment.
