A 15-year- old male castrated English setter was presented for evaluation of a rapidly growing oral mass. Patient’s history was otherwise unremarkable, except of moderate proteinuria of 5 years duration. Clinical examination findings were within normal limits, except of an ulcerated located at the left mandibular canine tooth, which was histologically confirmed as a high grade infiltrative fibrosarcoma with high mitotic index (61/10 HPF) and multifocal necrotic areas. The client declined full staging, so only hematological and biochemistry examinations of blood were performed, which were without any clinically significant alterations. Furthermore a fine needle aspiration biopsy of regional lymph nodes was performed, which revealed reactive lymphadenopathy without signs of metastases. After declining other more invasive therapeutic procedures, the clients elected treatment with combination of electrochemotherapy and IL-12 electrogene therapy. Four consecutive treatment sessions were performed, resulting not only in complete response of the primary tumor, but also in regression of untreated distant metastasis, which was diagnosed approximately one month after the initial examination. Furthermore, the percentage of circulating CD8+ cells was increased after each therapy session, indicating possible systemic induction of immune response by IL-12 gene therapy. This case shows that this type of therapy can represent an alternative type of both local and systemic treatment in selected tumor cases, where clients seek a less invasive nonsurgical treatment.

The studies of the vascularization of the cerebrum in dog were performed on 80 cerebral hemispheres. It was found that the middle cerebral artery is the strongest vessel supplying blood to the cerebrum. The artery gets divided into ten permanent branches. Two olfactory arteries supply the region of the cerebrum located on the border between the old and the new cortex. The other eight supply the region of the new cortex: three branches aiming at the frontal lobe, two branches at the parietal lobe and three temporal branches aiming at temporal area. The frontal, parietal and temporal branches descended independently from the main trunk of the middle cerebral artery or formed a common trunk. Common trunks for respective groups of branches have been described as the rostral, dorsal and caudal middle cerebral artery. In 2.5% of cases there were two independent branches of the middle cerebral artery extending from the rostral cerebral artery.

Ticks are considered as harmful and economically important ectoparasites because their infestation seriously affects the cattle worldwide. Tick control with synthetic acaricides is not only dangerous for animal and human health but also causes environmental pollution. The present study was designed to evaluate the plant extracts in comparison with synthetic acaricides to control Hyalomma anatolicum . Five different concentrations (50, 100, 250, 500 and 750 ppm) of methanolic plant extracts and acaricides, were employed to evaluate the mortality of ticks after 2, 4, 6, 12, 24 and 48 hrs. Mortality data was analyzed through Probit analysis to calculate the median lethal concentration (LC 50 ) and the median lethal time (LT 50 ). Methanolic extract from Azadirachta indica demonstrated the highest mortality (LC 50 = 38.3 ppm) of ticks as compared to Dalbergia sissoo (LC 50 = 58.76 ppm) and Morus alba (LC 50 = 92.95 ppm). Amongst acaricides, fipronil exhibited highest mortality (LC 50 = 35.01 ppm) when compared with emamectin (LC 50 = 46.87 ppm) and cypermethrin (LC 50 = 37.83 ppm). Higher concentration (750 ppm) of acaricides (fipronil, emamectin and cypermethrin) displayed quicker mortality (LT 50 = 6.53-8.95 hrs) as compare to the plant extracts (LT 50 = 8.49-29.17 hrs). Effects of these treatments were also studied on egg masses and reproductive index (RI) of the surviving ticks. The results revealed a significant, concentration-dependent variation among the egg masses treated with plant extracts and acaricides; and subsequently, their reproductive index values also decreased significantly. Phytochemical analysis of the tested plant extracts revealed presence of flavonoids, steroids, terpenoids, saponins, tannins and phenols in variable quantities. Conclusively, our results describe a significant scope of environment friendly plant extracts for ticks’ management.

This study reported the chemical composition of Tualang honey and its effect on the lung surfactants and histology of male rats exposed to cigarette smoke. Thirty-two adult male Sprague-Dawley rats were used and they were randomly divided into 4 groups of eight rats each: control, honey-treated (Honey), cigarette smoke-exposed (CS) and honey-treated plus CS (Honey+CS). Rats in control and CS groups received distilled water (0.5 mL/day) while rats in Honey and Honey+CS groups received honey (1.2 g/kg body weight/day) by oral gavage. Furthermore, rats in CS and Honey+CS groups were exposed to CS in a chamber for 8 minutes (3 times/day). Exposure of rats to cigarette smoke significantly altered their phosphatidyl choline/ phosphatidyl glycerol (PC/PG) ratio but not their surfactant protein A levels with increased number of alveolar macrophage containing carbon particles. Administration of Tualang honey to CS exposed rats resulted in modulation of most of these parameters and which results were coroborrated by histology. The colour intenstity, pH and moisture content of the honey were obtained as 272.75 mili-absorbance unit, 3.43 and 17.38%, respectively. Screening for phenolic compounds in Tualang honey using High Performance Thin Layer Chromatography showed the presence of 18 compounds while only five were identified which possessed strong in vitro antioxidant capacity as seen from their 2,2,diphenyl-1-picryl hydrazyl radical scavenging ability. The study showed the promising potentials of Tualung honey in protecting lung surfactants from the deleterious action of cigarette smoke which may be associated with its antioxidant phenolic compounds.

This study was carried out to evaluate the efficacy of vaccination of layer chickens with inactivated FC bacterin prepared from local Egyptian strains of Pasteurella multocida ( P. multocida ). A total of 200 layer chickens were divided into 5 equal groups, 40 for each. At the age of 6 weeks, chickens in groups (A) and (B) were vaccinated with P. multocida serotypes A:1 and A:3, respectively, booster doses were given after 3 weeks (9 weeks old) and challenge was done with virulent serotypes A:1 and A:3 at 2 weeks later (11 weeks old). Chickens in groups (C) and (D) were not vaccinated, only challenged with P. multocida serotype A:1 and A:3, respectively. Birds in group (E) were kept as non-vaccinated and non-challenged. Blood samples were collected weekly from all groups for humoral immune response. All the birds were kept under observation for signs, mortalities, lesions and re-isolation of challenging organism and for histopathological examination. Results of the mean Enzyme Linked Immuno-Sorbent Assay (ELISA) revealed that the highest level was at 5 weeks post vaccination as the titers reached to 3970 in group (A) and 3905 in group (B). The clinical signs, mortality rate and lesions were mild in the vaccinated birds while severe lesions were in non-vaccinated and challenged birds. The protection rates were 85 % and 80 % in groups (A) and (B); respectively, while 10 % and 20 % in groups (C) and (D); respectively. The re-isolation rates of P. multocida after challenge were 95 % and 90 % in non-vaccinated-challenged birds with P. multocida serotypes A:1 and A:3; respectively, while they were 25 % and 15 % in vaccinated-challenged groups with P. multocida serotypes A:1 and A:3; respectively. Histopathological examination of P. multocida vaccinated-challenged birds revealed mild to no microscopic lesions when compared with non-vaccinated challenged chickens.

This study was conducted to investigate the effects of calorie restriction and dietary bee products (apilarnil plus royal jelly) supplementation on reproductive and oxidative responses and to determine the possibilities that these treatments may be used in retarding the reproductive ageing of broiler breeder males. At 52 weeks of age, broiler breeder males were assigned to four treatment groups. The control group was fed on restricted feed as recommended by the breeder company throughout the study; the ad libitum group was fed ad libitum for a four-week period; the bee products group was fed similar to the control group except that their diet was supplemented with apilarnil and royal jelly for a four-week period and in the last group calorie restriction (45 % of standard diet) was applied for a four-week period. After a four-week adaptation period, the experiment was continued for 18 weeks. The results obtained in the present study have demonstrated that the percentage of dead sperm was the most affected semen characteristic by reproductive ageing. Long-term moderate feed restriction could not prevent age-related declines in sperm production. Dietary bee products supplementation or calorie restriction for a fourweek period positively affected the semen characteristics, and these beneficial effects could be maintained to some extend up until 72 weeks of age. Calorie restriction enhanced antioxidant defence for the first four-week period; however, this beneficial effect could not be sustained until the end of the experiment.

The current study focused on investigating the renoprotective effects of grape seed oil (GSO) against hexavalent chromium (Cr (VI))-induced nephrotoxicity. A total of 40 male rats were randomly divided into four groups: group I served as the control group, group II received 1000 mg/L potassium dichromate (353.5 mg/L Cr(VI)) in drinking water for 12 weeks, group III received 3.7 g/kg body weight/day GSO orally for 12 weeks, and group IV received GSO together with potassium dichromate for 12 weeks. Cr(VI) significantly increased serum levels of urea, creatinine, potassium and glucose. In addition, Cr(VI) increased MDA levels and induced renal tissue damage and DNA damage. On the other hand, Cr(VI) decreased serum levels of sodium and antioxidant defence system [reduced glutathione (GSH) and catalase (CAT)]. However, treatment with GSO prevented elevation levels of serum urea, creatinine, potassium and glucose. In addition, GSO enhanced sodium level, renal tissue antioxidant defense system due to its curative effect ameliorated particularly oxidative stress, renal tissue and DNA damage. In conclusion, these results demonstrate that GSO is a promising nephroprotective agent against Cr(VI)-induced nephrotoxicity.

The aim of this study was to determine the microbiological loads of small animal carcasses, carcass lymph nodes, whole liver surface, liver lymph nodes and some tools contacting with carcass and offal. Total 630 samples taken from small animal carcasses, livers, hepatic lymph nodes, subiliac and prescapular lymph nodes, staff knives and slaughterhouse tools samples (stainless steel table, plastic crates, offal carts) were investigated for mesophilic aerobic bacteria, Enterobacteriaceae , Escherichia coli counts and Salmonella spp. The mean total aerobic mesophilic bacteria (TAMB), Enterobacteriaceae and E. coli numbers of the carcasses were 3.6, 0.6, and 0.1 log 10 CFU/cm 2 , respectively, and the most contaminated region among the carcass sampling points was flank. The mean TAMB, Enterobacteriaceae and E. coli counts of the liver surfaces were 6.0, 3.7, 2.9 log 10 CFU/liver, respectively. The average TAMB, Enterobacteriaceae and E. coli numbers of the knives were found as 6.3, 2.9 and 2.1 log 10 CFU/blade, and the average TAMB, Enterobacteriaceae and E. coli counts of the slaughterhouse surfaces were 5.1, 1.6, 0.5 log 10 CFU/cm 2 . Salmonella spp. was detected in 4% of the liver samples and 10% of the knives samples. Consequently, the presence of Salmonella on the surface of livers and blades, and high number of E. coli on the livers, blades and tools show that a public health risk may arise at any time, and staff should pay extra attention to the “Good Hygiene Practices” and Food Safety Management Systems (such as HACCP) applied in slaughterhouses.

We studied the acute and sub-acute toxicity of Combretum dolichopetalum leaves in experimental mice and rats respectively using standard techniques. The LD 50 of the methanol extract of Combretum dolichopetalum leaves as carried out in experimental mice was obtained as more than 5000 mg/kg body weight. Administration of graded doses (100, 200, 400 and 800 mg/kg) of the extract for 21 days resulted in increases in body weights, white blood cells (WBC), Neutrophils, red blood cells (RBC), packed cell volume (PCV), haemoglobin (HGB), mean corpuscular volume (MCV) and mean cell haemoglobin (MCH) of the rats; but did not affect (P>0.05) their monocytes, mean cell haemoglobin concentration (MCHC), platelet (PLT) levels. All doses of the extract did not affect (P>0.05) the sodium, potassium, chloride, bicarbonate, urea, creatinine, total and conjugated bilirubin, alanine and aspartate amino transaminase, aspartate amino transaminase, alkaline phosphatase activities; relative liver and kidney weights of the rats, a finding that was corroborated by histology of the liver and the kidney. The extract at 100 mg/kg had no effect on the PCV and HB of the rats. The study suggested the therapeutic potentials of Combretum dolichopetalum as a blood booster. Finally, the study revealed the safety in the usage of Combretum dolichopetalum leaves in Nigerian ethnomedicine.

Here we present the first welfare assessment of commercial layers conducted in Slovenia. Hens were assessed in four systems at the beginning of the laying period at 22 to 24 weeks and at 50 to 55 weeks of age. These systems were an enriched battery cage system, an aviary, and a litter system with or without outdoor access. Clinical inspections of flocks were performed, and animal-based welfare indicators were scored (e.g., keel bone damage, feather condition, foot pad lesions, beak deformities, and comb and skin wounds). Hens’ fear level was scored using the novel object test and avoidance distance test. Among resource-based measures, selected micro-climate parameters were measured. The results showed no obvious clinical signs related to infectious diseases and suggest that the selected climate conditions were satisfying in all systems. Among animal-based welfare indicators, keel bone damage was shown to be the most serious problem connected with hens’ age and housing systems ( p < 0.05). Enriched cages and aviary system were associated with significantly more keel deformities compared to the litter systems ( p < 0.05). In addition, the least prevalence of foot pad dermatitis together with better feather condition was observed in the litter systems. In the family-owned aviary facility, hens were found to be the most motivated to approach a novel object or a human, and as such were recognized as the least fearful birds, with better human–animal interaction compared to other intensive housing systems. Key words: laying hens; welfare; health; housing system OCENA DOBROBITI V INTENZIVNIH REJAH KOKOSI NESNIC V SLOVENIJI Povzetek: Opravili smo prvo celovito oceno dobrobiti kokosi nesnic v Sloveniji. V raziskavo smo vkljucili nesnice iz stirih razlicnih sistemov reje in raven dobrobiti ocenili v dveh starostnih obdobjih; na zacetku nesnosti, v starosti od 22 do 24 tednov in pri 50 do 55 tednih. Nesnice so bile rejene v obogatenih kletkah, v voljerah, v talni reji brez možnosti izpusta in v talni reji z možnostjo izpusta. Ob vsakem ocenjevanju smo jate klinicno pregledali in s pregledom posameznih živali ocenili specificne indikatorje dobrega pocutja (poskodbe prsnice, operjenost, poskodbe podplatnih blazinic, deformacije kljuna in poskodbe grebena ter kože). Plasnost kot indikator socialnega obnasanja smo ocenili s testom novega predmeta in s testom odmika od cloveka. Spremljali smo tudi mikro-klimatske pogoje reje. Ves cas spremljanja nismo ugotovili vidnih klinicnih znakov kužnih obolenj. Rezultati meritev mikro-klimatskih parametrov nakazujejo, da so bili pogoji v rejah dobri. Poskodba prsnice se je izmed specificnih kazalnikov izkazala za najresnejsi problem, na katerega vplivata tako starost kot sistem reje ( p < 0,05). Poskodbe prsnice so bile znacilno bolj izražene pri kokosih iz obogatenih kletk in voljer ( p < 0,05) v primerjavi z nesnicami iz talnih rej. Kokosi iz talnih sistemov so bile tudi boljse operjene in so imele nižjo prevalenco poskod
在这里，我们提出了在斯洛文尼亚进行的商业层的第一个福利评估。在蛋鸡产蛋初期(22 ~ 24周龄)和50 ~ 55周龄(50 ~ 55周龄)分4个体系进行评估。这些系统是一个强化的电池笼系统，一个鸟舍和一个有或没有室外通道的垃圾系统。对鸡群进行临床检查，并对动物福利指标进行评分(例如，龙骨损伤、羽毛状况、脚垫病变、喙畸形、鸡冠和皮肤伤口)。采用新对象测试和回避距离测试对母鸡的恐惧程度进行评分。在基于资源的措施中，测量了选定的小气候参数。结果表明，各系统所选气候条件均令人满意。在动物福利指标中，蛋鸡的龙骨损伤与鸡龄和鸡舍制度有关(p < 0.05)。强化笼和鸟舍系统的龙骨畸形显著高于废砂系统(p < 0.05)。此外，在凋落物系统中，脚垫皮炎的患病率最低，羽毛状况较好。在家庭拥有的鸟舍设施中，母鸡被发现是最有动力接近新物体或人类的，因此被认为是最不害怕的鸟类，与其他密集的住房系统相比，人与动物的互动更好。关键词:蛋鸡;福利;健康;住宅系统:OCENA DOBROBITI V INTENZIVNIH REJAH KOKOSI NESNIC V SLOVENIJI Povzetek: Opravili smo provo celovito oceno DOBROBITI KOKOSI NESNIC V SLOVENIJIV . raziskavo, V . raziskavo, V . raziskavo, V . raziskavo, V . raziskavo, V . raziskavo, V . raziskavo, V . raziskavo, V . raziskavo, V . raziskavo, V . raziskavo, V . raziskavo, V . raziskavo, V . raziskavo;Na zacetku nesnosti, v starosti od 22 do 24 tetenov in pri 50 do 55 tetenih。nenice so bile rejene v obogatenih kletkah, v voljerah, v talni reji brez možnosti izpusta in v talni reji z možnostjo izpusta。Ob vsakem ocenjevanju smo jate klinicno pregledali in s pregledom posameznih živali ocenili特异性indickatorje dobrega pocuja(可能是price, operjenost，可能是podplatnih blazinic, deformacije kljuna in可能是grebena ter kože)。血浆酶标物(pplnost - kot)指标社会基因(socialnega obnasanja smo - seni)、睾丸激素(novega - premeta)、睾丸激素(odmika - cloveka)。Spremljali smo - tui microklimatske pogoje reje。2 .请注意，我们的工作人员是如何做到这一点的?Rezultati meritev - microklimatskih parameter - nakazujejo, da so bili pogoji v .
