    Opis:
    Purpose – The aim of the study was to assess the impact of the location of farms, the quality of natural conditions and fragmentation of agricultural holdings on the rate of landowners’ departure from agricultural activity, including cattle and pig farming. Research method – The study covered six provinces: Dolnośląskie, Małopolskie, Lubelskie, Mazowieckie, Pomorskie, Wielkopolskie. The considerations carried out were conducted in the system of districts for the years 2004-2016. Results – The largest decrease in the number of direct payment beneficiaries in the years 2004-2016 was recorded in the districts located on the outskirts of metropolitan areas. It was observed that in territorial units which obtained a higher evaluation of the quality of agricultural production space the regression in terms of the number of farms involved in animal production was significantly smaller, and the decrease in the number of single area payment beneficiaries was also smaller. In districts with relatively good natural conditions, faster departue from cattle and pig rearing was facilitated by the fragmentation of the area structure of farms. Originality / value / implications / recommendations – So far,the lack of detailed analyses of changes taking place in agriculture in Polish metropolitan areas has been noted, while this issue has been an important field of interest for researchers in the world for several decades. Therefore itmeans that work should be considered innovative. The results of the undertaken considerations constitute a significant contribution to explaining the reasons for the deagrarianisation of rural areas.

    Opis:
    The aim of the present study was to assess the haemolytic and proteolytic activity of coagulase- negative staphylococci (CNS) isolated from cows with mastitis. The study was conducted on 100 CNS strains: S. xylosus (n=28), S.chromogenes (n=26), S.haemolyticus (n=25), S. sciuri (n=14), S. warneri (n=4), S.hominis (n=2), S.saprophyticus (n=1); 22 CNS were isolated from cows with clinical mastitis and 78 from those with subclinical mastitis. The CNS studied showed the ability to produce only α-haemolysin and belonged to one strain – S. haemolyticus (21.0% of isolated CNS strains). Haemolysin-positive CNS were responsible for both clinical and subclinical mastitis (22.7% and 20.5%, respectively). The ability to produce protease was found in 31.0% of CNS belonging to two strains: S. chromogenes and S. sciuri. Protease-positive CNS were the etiological factor of both clinical and subclinical mastitis (31.8% and 30.8%, respectively). All S. xylosus, S. warneri, S. hominis, and S. saprophyticus strains were found protease-negative and haemolysin-negative, irrespective of whether they caused clinical or subclinical mastitis in cows.

    Opis:
    Background. The risk for public health posed by endocrine disruptors present in food is relatively new issue. Our current understanding of human exposure is mainly based on the residue analysis of selected compounds. With such approach potential, effects of mixtures, including so-far unidentified compounds are not taken into consideration. Therefore, the knowledge of overall hormonal activity in food samples is of big importance. Objective. Milk and dairy products are a rich source of estrogens but very rarely undergo testing for estrogenic activity. For this reason the rodent uterotrophic bioassay is one of the most useful tool. This preliminary study was conducted in immature hamsters to assess commercially available milk. The endpoint measured was uterine weight increase. Material and methods. Fifteen-day old females received ad libitum throughout 7 days commercially available milk i.e. raw goat’s, raw cow’s, processed 3.2% UHT, and for comparison soy milk. The animals of negative control group received water but positive control group got 17β - estradiol (E2) at the concentration of 100 ng/ml. Results. All samples of milk showed estrogenic activity as follow: goat’s >cow’s >soy >processed milk. Significant increase of uteri weights were recorded in goat’s (p<0.001) and cow’s milk (p<0.01). However, the activity was approximately 5-fold lower than induced by 17β-estradiol. The ratio uterine weight/body weight (%) in negative control was 0.096%, in milk experimental groups ranged from 0.112% to 0.153% and in positive control this value was 0.493%. Conclusion. The results suggest that commercially available milk has a weak uterotrophic activity. Further in vivo and in vitro studies are warranted to gain more insight into the estrogenic risk from milk and other dairy products.
    Wprowadzenie. Zagrożenie ze strony związków hormonalnie aktywnych pobieranych z żywnością jest nowym wyzwaniem w ochronie zdrowia publicznego. Jak dotąd ocena narażenia ludzi opiera się na podstawie analizy pozostałości wybranych związków. Takie podejście nie pozwala na przewidywanie efektów oddziaływania związków niezidentyfikowanych oraz ich mieszanin. Dlatego też znajomość ogólnej aktywności hormonalnej w próbkach żywności ma duże znaczenie. Cel pracy. Mleko i jego produkty są obfitym zewnętrznym źródłem estrogenów lecz rzadko podlegają badaniu w kierunku aktywności estrogennej. Jednym z bardziej przydatnych biotestów umożliwiających taką ocenę jest test wzrostu macicy wykonywany na gryzoniach. Celem pracy była wstępna ocena aktywności estrogennej mleka dostępnego na rynku krajowym z wykorzystaniem niedojrzałych płciowo samic chomika złocistego. Materiał i metody. Samicom w wieku 15 dni podawano ad libitum przez 7 dni mleko surowe kozie, krowie, przetworzone 3,2% UHT i dla porównania mleko sojowe. Zwierzęta kontroli negatywnej i pozytywnej otrzymywały odpowiednio wodę lub 17β- estradiol (E2) w stężeniu 100 ng/ml. Wyniki. Wszystkie rodzaje badanego mleka wykazywały aktywność estrogenną (mleko kozie>krowie>sojowe>3,2% UHT). Statystycznie istotny wzrost masy macicy zanotowano dla mleka koziego (p<0,001) i krowiego (p<0,01). Jednakże wartości te był około 5-krotmie mniejsze niż w kontroli pozytywnej. Stosunek masy macicy/masy ciała (%) w grupie kontroli negatywnej wynosił 0,096%, grupach otrzymujących mleko zawierał się w zakresie 0,112% -0,153%, a kontroli pozytywnej – 0,493%. Wniosek. Uzyskane wyniki wskazują, że mleko dostępne w sprzedaży wykazuje aktywność biologiczną w teście wzrostu macicy. Aby uzyskać więcej informacji o potencjalnym ryzyku niezbędne są dalsze badania nad oceną aktywności estrogennej mleka z uwzględnieniem także przetworów mlecznych.

    Opis:
    The experimental materials comprised 44 hybrid [ (♀Polish Large White x Polish Landrace) x ♂Duroc] growing-finishing pigs. The animals were randomly divided into two groups: 24 pigs were slaughtered immediately after transport and 20 pigs were slaughtered after a 24-hour rest period in the lairage. The meat content of pork carcasses, carcass dressing percentage, the proximate chemical composition, physicochemical and sensory properties of meat and shear force values were determined. Serum creatine kinase activity and cortisol levels were determined in blood samples collected before transport and during carcass bleeding. Pigs slaughtered immediately after transport, compared with those slaughtered after a 24-hour rest period, were characterized by a higher meat content of the carcass and a higher carcass dressing percentage. Pre-slaughter handling had no effect on pork quality. The incidence of normal-quality meat, partially PSE (pale, soft, exudative) meat and PSE meat was similar in both groups. Chemical analysis showed that the content of dry matter, total protein, fat and minerals in meat was comparable in both groups. As regards the functional properties of the pork, samples from the carcasses of pigs that had rested before slaughter had a higher contribution of the red color component. Meat from pigs slaughtered immediately after transport had more desirable sensory properties. Pre-slaughter resting had a significant effect on those analyzed physiological parameters which were found to be good indicators of pre-slaughter stress. Serum creatine kinase activity and cortisol levels were higher in blood samples collected after transport (during carcass bleeding) than in samples collected before transport, pointing to a strong stress response of animals to pre-slaughter treatment. The decrease in serum cortisol levels in blood samples collected during bleeding from the carcasses of pigs slaughtered after a 24-hour rest period, compared with samples collected from animals slaughtered immediately after transport, suggests that rest before slaughter alleviated stress induced by pre-slaughter handling operations.

    Opis:
    Introduction. The standard porcine-derived pancreatic enzyme replacement therapy (PERT) is a lifesaving treatment for patients with diseases causing exocrine pancreatic insufficiency (EPI). An attempt to replace PERT with microbial enzymes were undertaken. The aim was to highlight whether the mode of application, mixed with food or applied directly to the stomach, of pancreatic-like enzymes of microbial origin (PLEM) can affect their activity along the gastrointestinal tract. Materials and method. The activity of amylase, lipase and proteinase in the stomach, duodenum and ileum were tested in EPI pigs (n=6) after supplementation of PLEM, either orally – before and during feed consumption – or via the stomach – before and during feed consumption. Healthy pigs not treated with PLEM (n=3) served as controls. Activity of the enzymes measured in the chyme were obtained together with the digesta pH. Activity of the enzymatic residues in the stool samples was also checked. Results. The highest pancreatic enzyme activities were found in the duodenum of the healthy pigs (amylase 162,68 kU/ mL, lipase 507,34 kU/mL and protolitic (trypsin) activity 357,60 kU/mL). Nevertheless, the microbial enzymes remained also active along the entire length of the GIT – including stomach in EPI pigs, regardless of their route of administration. However, activity level was significantly lower. Discussion. Results indicate that the activity pattern of PLEM in the small intestine mimics the activity of the natural endogenous pancreatic enzymes in healthy pigs. The most physiological features of PLEM were observed when enzymes were offered orally. The magnitude of PLEM activity in the stomach of EPI pigs was essential and significantly higher than that measured in healthy pigs, thus being somewhat not physiological, and for health reasons of the patients should be further explored. Interestingly, specific trypsin-like activity was measured in all parts of the GIT after PLEM application. However, proteolytic activity of the experimental proteaze in in vitro studies did not exhibit trypsin-like activity.

    Opis:
    Sialic acids are important constituents of animal tissue glycoconjugates and are also present in the antigens of some bacterial strains. Capsular polysaccharides with sialic acid (NeuAc) have been extensively studied with regard to sensitivity to the bactericidal action of serum, whereas little is known in this regard about lipopolysaccharides (LPS) which contain NeuAc. Strains of Salmonella 048, able to infect animals and containing the same structures of LPS with NeuAc, were examined for their susceptibility to the bactericidal action of normal bovine serum (NBS). The strains showed varied sensitivity to the bactericidal action of NBS, which indicates that the expression of LPS containing NeuAc residues is not critical for the strains' resistance to the serum's activity. In this study the mechanisms of complement activation responsible for killing serum-sensitive Salmonella 048 rods by NBS were also established. Three such mechanisms were distinguished: activation of the classi- cal/lectin pathways, important (decisive) in the bactericidal mechanism of complement activation, parallel activation of the classical/lectin and alternative pathways, and independent activation of the classical and lectin or the alternative pathway.

    Opis:
    Animal models based on N-methyl-d-aspartate (NMDA) receptor blockade have been widely reported. Ketamine and MK-801, the two noncompetitive antagonists of NMDA receptors, produce behaviors related to schizophrenia and exacerbated symptoms in patients with schizophrenia. The study presented here investigated the effect of subchronic dosing (once-daily, 7 day) of histamine H3 receptor (H3R) antagonists, ciproxifan (CPX) (3 mg/kg, i.p.) and clobenpropit (CBP) (15 mg/kg, i.p) including clozapine (CLZ) (3.0 mg/kg, i.p.) and chlorpromazine (CPZ) (3.0 mg/kg, i.p.), the atypical and typical antipsychotic, respectively, on MK-801(0.2 mg/kg, i.p.)-induced locomotor activity, and dopamine and histamine levels in rats. Atypical and typical antipsychotic was used to serve as clinically relevant reference agents to compare the effects of the H3R antagonists. MK-801 significantly increased horizontal activity which was reduced with CPX and CBP. The attenuation of MK-801-induced locomotor hyperactivity produced CPX and CBP were comparable to CLZ and CPZ. Dopamine and histamine levels were measured in striatum and hypothalamus, respectively, of rat brain. The MK-801 induced increase of the striatal dopamine level was reduced in rats pretreated with CPX and CBP including CLZ. CPZ also significantly lowered striatal dopamine levels, though the decrease was less robust compared to CLZ, CPX and CBP. MK-801 increased histamine content although to a lesser degree. Subchronic treatment with CPX and CBP exhibited further increased histamine levels in the hypothalamus compared to MK-801 treatment alone. Histamine H3 receptor agonist, R-α methylhistamine (10 mg/kg, i.p.) counteracted the effect of CPX and CBP. The findings of the present study support our previous work showing positive effects of CPX and CBP on MK-801-induced schizophrenia like behaviors in rodents. However, clinical studies have reported no antipsychotic effects with histamine H3 receptor antagonists.

    Opis:
    The control of trypanosomosis in animals and humans based on chemotherapy is limited and not ideal, since the agents used are associated with severe side effects, and emergence of relapse and drug resistant parasites. The need for the development of new, cheap and safe compounds stimulated this study. Three concentrations (211, 21.1 and 2.11 mg per ml) of chloroform stem bark extract of Annona muricata were screened for trypanocidal activity against Trypanosoma brucei brucei in vitro. Also, two doses (200 mg per kg and 100 mg per kg) of the extract were evaluated for trypanocidal activity in rats infected with the parasite. Haematological parameters were determined on day 1 post infection and on days 1, 6 and 30-post extract treatment. The extracts inhibited parasite motility and totally eliminated the organisms at the concentrations used in vitro. The extract also showed promising in vivo trypanocidal activity. The observed in vitro and in vivo trypanocidal activities may be due to the presence of bioactive compounds present in the extracts as seen in this study. The extract also improved the observed decreases in haematological parameters of the treated rats, which may be due to their ability to decrease parasite load. The observed oral LD50 of 1,725.05 mg per kg of the chloroform A. muricata extract using up and down method is an indication of very low toxicity, implying that the extract could be administered with some degree of safety.
    Leczenie chemioterapeutykami śpiączki afrykańskiej, tak u ludzi jak i u zwierząt, jest trudne ze względu na powstawanie wielu poważnych objawów niepożądanych oraz wywoływanie zjawiska oporności podczas ich stosowania, co powoduje brak skuteczności i pojawianie się nawrotów tej choroby. Stąd potrzeba znalezienia nowego skutecznego i taniego leku była powodem podjęcia badań przedstawianych w tej pracy. Celem badań było określenie aktywności wyciągu chloroformowego z kory Annona muricata stosowanego w warunkach in vitro dla trzech stężeń (211, 21,1 i 2,11 mg/ml) przeciwko aktywności Trypanosoma brucei brucei. Ponadto w badaniach in vivo określano aktywność tego ekstraktu w dwóch dawkach (100 i 200 mg/kg) u szczurów zarażonych pasożytem. Do oceny stanu zwierząt wykorzystano pomiar odpowiednich parametrów hematologicznych po 1 dniu od ich zainfekowania oraz po 1, 6 i 30 dniu podawania badanego wyciągu. W badaniach in vitro we wszystkich zastosowanych stężeniach wyciąg hamował ruchliwość omawianego pasożyta. Ponadto w badaniach in vivo ekstrakt całkowicie eliminował obecność Trypanosoma brucei brucei u zainfekowanych zwierząt, wykazując w ten sposób obiecującą aktywność przeciwko trypanosomatozie. Zaobserwowane działanie, tak in vitro jak i in vivo, było być może związane z obecnością związków czynnych charakteryzujących stosowany wyciąg. Analizowany ekstrakt, prawdopodobnie ze względu na obniżenie liczby pasożytów po jego podawaniu, miał także zdolność poprawiania parametrów hematologicznych u zainfekowanych zwierząt. Ze względu na otrzymaną wartość LD50 dla zastosowanego wyciągu chloroformowego z kory Annona muricata, wynoszącą 1725,05 mg/kg po podaniu dożołądkowym szczurom, można sądzić, że stosowanie badanego wyciągu jest względnie bezpieczne.

    Opis:
    Background. The influence of infection with two species of entomopathogenic nematodes of Steinernematidae family on the activity of superoxide dismutase (SOD) of the host was studied. Material and methods. Last instar larvae of Galleria mellonella were experimentally infected with Steinernema affinis and S. feltiae at 20 invasive juveniles per insect. At 6, 12, 18, 24 and 36 h after infection activity of SOD was determined in extracts from infected and control insects. Results. The activity of SOD decreased gradually in the controls during the experiment. The activity of enzyme was 2-4-times higher in insects from both infected groups than in the control. During the first 12 h of infection the activity of SOD in insects infected with S. feltiae was higher than in those infected with S. affinis, then the activity of enzyme in the insects of both infected groups stayed at a similar level. A significant decrease of SOD activity in infected was recorded in second day of the infection.

    Opis:
    Plant derived extracts and phytochemicals have long been a subject of research in an effort to develop alternatives to conventional insecticides but with reduced health and environmental impact. In the present study, the aphid settling deterrent activity of extracts obtained from garlic (Allium sativum L.), wormwood (Artemisia absinthium L.) and tansy (Tanaceum vulgare L.) against peach potato aphid (Myzus persicae [Sulz.]) was investigated. The settling of M. persicae on host plant leaves was strongly deterred by soap 1%, soap 4%, Bioczos Forte 2% + soap 1%, Bioczos 1% + tansy extract 1%. Their effect was observed after 1 hour aphid had got access to the plants and it lasted until the end of the experiment, i.e. 24 hours after application. After 24 hours, aphid settling was deterred by the following combinations of extracts: Bioczos 2%, Bioczos 2% + soap 1%, Bioczos 5%, Bioczos 5% + soap 1%, Bioczos 1% + wormwood extract 1%, Bioczos 1% + wormwood extract 1% + soap, tansy extract 1% + wormwood extract 1% and tansy extract 1% + wormwood extract 1% + soap 1%.

    Opis:
    Flavonoids and their conjugates are the most important group of natural chemical compounds in drug discovery and development. The search for pharmacological activity and new mechanisms of activity of these chemical compounds, which may inhibit mediators of inflammation and influence the structure and function of endothelial cells, can be an interesting pharmacological strategy for the prevention and adjunctive treatments of hypertension, especially induced by pregnancy. Because cardiovascular diseases have multifactorial pathogenesis these natural chemical compounds with wide spectrum of biological activities are the most interesting source of new drugs. Extracts from one of the most popular plant used in Traditional Chinese Medicine, Scutellaria baicalensis Georgi could be a very interesting source of flavonoids because of its exact content in quercetin, apigenin, chrysin and scutellarin as well as in baicalin. These flavonoids exert vasoprotective properties and many activities such as: anti-oxidative via several pathways, anti-inflammatory, anti-ischaemic, cardioprotective and anti-hypertensive. However, there is lack of summaries of results of studies in context of potential and future application of flavonoids with determined composition and activity. Our review aims to provide a literature survey of in vitro, in vivo and ex vivo pharmacological studies of selected flavonoids (apigenin, chrysin and scutellarin, baicalin) in various models of hypertension carried out in 2008–2018.
