Abstract
This study examines long-term ocean pH data to evaluate ocean acidification (OA) trends at two coastal research institutions located on the Sea of Japan and the Pacific Ocean. These laboratories are located away from the influences of large rivers and major industrial activity. Measurements were performed daily for the past 30 years (1980s–2010s). The average annual ocean pH for both sites showed generally negative trends. These trends were – 0.0032 and – 0.0068 year–1 (p < 0.001) at the Sea of Japan and Pacific Ocean sites, respectively. The trends were superimposed onto approximately 10-year oscillations, which appear to synchronize with the ocean current periodicity. At the Sea of Japan site, the ocean pH in the summer was higher, and the rate of OA was higher than during other seasons. Our results suggest that seasonality and ocean currents influence OA in the coastal areas of open oceans and can affect the coastal regions of marginal seas.

What natural and social scientists need from each other for effective marine environmental assessment: Insights from collaborative research on the Tomakomai CCS Demonstration Project. MARINE POLLUTION BULLETIN 2020; 159:111520. [PMID: 32777547 DOI: 10.1016/j.marpolbul.2020.111520] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/22/2020] [Revised: 07/24/2020] [Accepted: 07/24/2020] [Indexed: 06/11/2023]
Abstract
We propose actions to guide collaboration between 'natural' and 'social' science disciplines in marine environmental issues. Despite enthusiasm for interdisciplinarity on environmental issues, institutional and disciplinary barriers remain for interdisciplinary working in practice. This paper explores what natural and social scientists need from each other for more effective impact assessment in the marine environment. We reflect on collaboration between natural- (especially marine biology) and social scientists (especially environmental sociology) researching the Tomakomai CCS Demonstration Project in Japan; including subsequent expansion of the research team and wider evaluation of project outcomes. We identify two areas of mutual support: community and stakeholder engagement on marine monitoring; and identification of points in regulatory/policy processes where qualitative findings may gain traction alongside quantitative results. We suggest interdisciplinary collaboration for marine environmental research could be helped by making time to learn from each other within projects; and by working together more closely in the field.

Abstract
We investigated the effects of elevated pCO2 in seawater both on the acute mortality and the reproductive properties of the benthic copepod Tigriopus japonicus and gastropod Babylonia japonica with the purpose of accumulating basic data for assessing potential environmental impacts of sub-sea geological storage of anthropogenic CO2 in Japan. Acute tests showed that nauplii of T. japonicus have a high tolerance to elevated pCO2 environments. Full life cycle tests on T. japonicus indicated NOEC=5800μatm and LOEC=37,000μatm. Adult B. japonica showed remarkable resistance to elevated pCO2 in the acute tests. Embryonic development of B. japonica showed a NOEC=1500μatm and LOEC=5400μatm. T. japonicus showed high resistance to elevated pCO2 throughout the life cycle and B. japonica are rather sensitive during the veliger stage when they started to form their shells.

Abstract
Carbon capture and storage (CCS) methods, either sub-seabed or in ocean depths, introduces risk of CO2 leakage and subsequent interaction with the ecosystem. It is therefore important to obtain information on possible effects of CO2. In situ CO2 exposure experiments were carried out twice for 10 days during 2005 using a Benthic Chamber system at 400 m depth in Storfjorden, Norway. pCO2 in the water above the sediment in the chambers was controlled at approximately 500, 5000 and 20,000 μatm, respectively. This article describes the experiment and the results from measured the biological responses within the chamber sediments. The results show effects of elevated CO2 concentrations on biological processes such as increased nanobenthos density. Methane production and sulphate reduction was enhanced in the approximately 5000 μatm chamber.

Duration of hepatic vascular inflow clamping and survival after liver resection for hepatocellular carcinoma. Br J Surg 2011; 98:1284-90.

Abstract
BACKGROUND The aim of this study was to evaluate the influence of the duration of hepatic vascular inflow clamping (Pringle time) on the survival of patients with any type of liver background (not only cirrhosis) undergoing liver resection for hepatocellular carcinoma (HCC). METHODS Patients who underwent liver resection between April 2000 and December 2008 for HCC using the Pringle manoeuvre were identified retrospectively from an institutional database and divided into two groups: group 1 had a Pringle time of 60 min or less, and group 2 a Pringle time of more than 60 min. Univariable and multivariable analyses were performed to identify predictors of postoperative survival. Kaplan-Meier analysis was used to compare overall survival between the groups. RESULTS A total of 357 patients were enrolled; 242 patients had a Pringle time of 60 min or less (group 1), and 115 patients had a Pringle time of more than 60 min (group 2). Patients in group 2 had a shorter overall survival than those in group 1 (P = 0·010). Univariable analyses showed that type of HCC (primary versus recurrent), maximum tumour diameter, hepatic venous infiltration, platelet count, serum protein induced by vitamin K absence or antagonist II level, blood loss (700 ml or less versus more than 700 ml), duration of operation (300 min or less versus more than 300 min) and Pringle time (60 min or less versus more than 60 min) were predictive of postoperative survival. Multivariable analysis indicated that only Pringle time was associated with postoperative survival (odds ratio 1·83, 95 per cent confidence interval 1·08 to 3·10; P = 0·024). CONCLUSION Longer Pringle time is an important predictor of shorter postoperative survival in patients undergoing liver resection for HCC.

Abstract
A numerical simulation was conducted to predict the change of pCO(2) in the ocean caused by CO(2) leaked from an underground aquifer, in which CO(2) is purposefully stored. The target space of the present model was the ocean above the seafloor. The behavior of CO(2) bubbles, their dissolution, and the advection-diffusion of dissolved CO(2) were numerically simulated. Here, two cases for the leakage rate were studied: an extreme case, 94,600 t/y, which assumed that a large fault accidentally connects the CO(2) reservoir and the seafloor; and a reasonable case, 3800 t/y, based on the seepage rate of an existing EOR site. In the extreme case, the calculated increase in DeltapCO(2) experienced by floating organisms was less than 300 ppm, while that for immobile organisms directly over the fault surface periodically exceeded 1000 ppm, if momentarily. In the reasonable case, the calculated DeltapCO(2) and pH were within the range of natural fluctuation.

Abstract
Twelve horses, all of them 10 years old, were vaccinated intramuscularly on 0 and 28 days of the experiment with inactivated vaccine containing only antigens of A-equi-2/Miami/63. Another three unvaccinated horses, each at the age of 10 years, were the negative control group. One, ten-year-old horse was vaccinated with commercial inactivated vaccine containing both antigens of A-equi-2/Miami/63 as well as A-equi-1/Praha/56 as positive control. Three horses were challenged intranasally with homotypic strain of Miami/63, while six other were challenged with heterotypic strains--three with Suffolk/89 and three with Kentucky/86. Three horses vaccinated with vaccine containing only strain A-equi-2/Miami/63 were not challenged. In the group of three unvaccinated horses, each one was challenged intranasally with different strains studied in this experiment. The horse vaccinated with commercial vaccine was not challenged. Replication of each strain was done in chick embryos. During the experiment blood from horses was collected for hematological and immunological examinations (antigen-specific and antigen-nonspecific lymphocyte transformation tests, lymphocyte immunophenotyping, antigen-specific leukocyte migration inhibition test and hemagglutination inhibition test). The statistical analysis showed that the dynamics of lymphocyte immunological reactivity in horses vaccinated with inactivated vaccine containing antigens of A-equi-2/Miami/63 in response to further antigen stimulation (in vitro) was different comparing the homotypic or nearly homotypic challenging with Miami/63 and Suffolk/89 respectively, to the more heterotypic one with the strain Kentucky/86. In horses challenged with classical homotypic strain of Miami/63 no clinical signs were observed. These results confirm that the vaccine shall consist of the strains currently circulating in the horse population.

Abstract
OBJECTIVES In our previous study, scores determined via a multiple linear regression method (EN-MLR) involving an electronic nose provided objective halitosis-related measurements; however, this model afforded only relative expression exclusively. The objective of this investigation was to assess clinically oral malodor intensity expressed as an absolute value using an electronic nose. SUBJECTS AND METHODS Sixty-six subjects were evaluated based on results of an actual organoleptic test (OLT), measurements of volatile sulfur compound (VSC) concentrations, a score representing malodor intensity (EN-MI) as the absolute value and EN-MLR measured with an electronic nose system. Oral health parameters were also examined. RESULTS The OLT score served as a benchmark. The area under the receiver-operating characteristic (ROC) plots of EN-MI score (0.975) was significantly larger than that of log VSC (0.896) (P = 0.036); however, the area did not differ significantly from that of EN-MLR score (0.932). Percentage of teeth with pocket depth greater than or equal to 4 mm, tongue coating score and plaque control record displayed meaningful association with EN-MI score in multiple logistic regression analyses. CONCLUSION Oral malodor intensity expressed as an absolute value employing an electronic nose may be a suitable method for clinical evaluation of oral malodor.

Abstract
Ninety-seven bison (39 males and 58 females) were culled out during three successive winter seasons. No infection with BHV-1 and BHV-5 or other viruses was detected by PCR and SN methods. Advanced pathological lesions observed in males exhibiting symptoms of posthitis/balanoposthitis are probably due to secondary infection by microorganisms present in the prepuce (Corynebacterium spp., Bacillus spp., Fusobacterium necrophorum, Staphylococcus spp. (coagulase negative) and Staphylococcus hyicus). Histopathological examinations of sections from prepuce and lips of pudendum showed the presence of Onchocercinae nematode (Onchocerca sp.). A comparison of biochemical and morphological blood parameters in the bison with or without lesions in the digestive (presence of parasites), respiratory, urinary and reproductive tracts revealed that the most variable parameter during reproductive organ disorder is the leukocyte count, while disorders in the urinary and digestive tracts coincided with the age of animals. In cases of digestive disorder most changes were observed in the number of neutrophils and concentration of urea. The number of red blood cells, monocytes, the level of alkaline phosphatase (AP) and hematocrit negatively correlated with age. Negative correlation was also observed between the number of neutrophils, level of creatinine and lymphocyte proliferation index. However, positive correlation was seen between erythrocyte sedimentation rate (Spearman's correlation coefficient), level of alanine aminotransferase (ALT) and protein, and age of the bison. Positive correlation was also observed between the lymphocyte count and lymphocyte proliferation index. The attempt to determine the reference values for blood biochemical and morphological parameters showed similarities to those of cattle.

Abstract
Blood was collected from bison that were selected between 1991 and 2001 for poor body condition, cachexia, lameness and balanoposthitis. Sera were tested for antibodies to bovine herpes virus type 1 (BHV-1), bovine viral diarrhoea virus (BVDV), foot-and-mouth disease virus (FMDV), parainfluenza virus type 3 (PI-3), Brucella abortus, Chlamydophila abortus, Coxiella burnetti, and Leptospira interrogans. The results of serological tests showed a prevalence of low titers of a serological reaction to Chlamydophila abortus (45.1%), bovine viral diarrhoea virus (29.5%), Leptospira interrogans (21.3%) and parainfluenza virus type 3 (13.9%). There were differences in the prevalence of antibodies to Ch. abortus between female and male bison. Futhermore, a relationship between age and antibodies to BVDV was observed in older bison. These results suggest that there is some transmission of bacterial and viral pathogens occurring between domestic and wild ruminants grazing in the same pastures in the peripherial areas of Bialowieza Primeval Forest.

Abstract
An 81-year-old female patient was admitted to the emergency room of our hospital with complaints of respiratory distress, abdominal ache, nausea, and intermittent vomiting. A plain X-ray of the abdomen and chest revealed air-fluid levels on the abdomen and the right side of the chest. Laboratory tests showed severe acidemia with a blood base excess level of -24.9 mmol/L. Since the patient was considered to have acute intestinal obstruction due to transverse colon herniation into the thorax through a foramen of Morgagni, emergency surgery was performed. Operative findings revealed that the retrosternal diaphragm had a defect of 5 cm in diameter and 20 cm in length with the transverse colon herniated into the thorax. The diaphragm defect was sutured first, and partial resection of the transverse colon was performed. After the operation, the patient had no symptoms and no recurrence has been observed during the 1-year follow-up. There have been 263 reported cases of Morgagani hernia in Japan. The case of the Morgagni hernia is reported here with some bibliographical comments.

Abstract
CO(2) ocean storage by which liquefied CO(2) is injected into the deep-sea to mitigate the climate change would increase the CO(2) concentrations of the surrounding seawater. The biological impacts of such dynamic CO(2) environments are, however, unknown. We examined the acute toxicity of temporally changing seawater CO(2) concentrations on juveniles of Sillago japonica. Step-wise increases in ambient CO(2) to fCO(2) (fractional CO(2) concentration of the gas mixture bubbled into seawater) levels of 7% and 9% resulted in mortalities of 0.15 and 0.40-0.67 after 18 h, respectively. In contrast, one-step increases to these CO(2) levels killed all fish within 15 min. Further, a sudden drop of fCO(2) from 9-10% CO(2) to normocapnia (0.038%) killed all the surviving fish within a few minutes. These results demonstrate that impacts of ocean CO(2) storage need to be examined under conditions mimicking the dynamic changes in CO(2) levels expected to occur by the CO(2) injection procedure.

Abstract
The aim of this study was to investigate the structure of lymphatic organs in foals which died due to Rhodococcus equi infection. The material for this study consisted of 9 foals, of both genders, various breeds, 6-14 weeks old. The routine histopathological examination and immunocytochemical reaction for cytokeratine-3 receptors revealed the disturbances in the thymus epithelial cells development. This was manifested by a complete lack of cells expressing cytokeratine-3 receptors, as well as absence of normal thymocytes differentiation. The supposed thymus epithelial cells were very few, expressing faint reaction of cytokeratine-3 receptors. The relative deficiencies in the lymphatic tissue development in peripheral lymphatic organs were observed. It was concluded, that the observed pathological changes may indicate the inherited, not described yet gene failure, which was responsible for the thymus epithelial cells developmental disturbances, and was expressed with various intensity in examined foals. The causes of the fatal course of rhodococcosis in foals were primary disturbances in the immune competence.

Prevalence of the suilysin gene in Streptococcus suis strains isolated from diseased and healthy carrier pigs. Pol J Vet Sci 2005; 8:141-5.

Abstract
Knowledge of virulence factors of Streptococcus suis is limited. Several virulence factor candidates have been proposed, among them suilysin, which is responsible for a toxic effect on epithelial cells. The aim of this study was to detect the suilysin gene sequence in Streptococcus suis strains of various origin. In total 63 Streptococcus suis isolates were investigated. Forty four of them originated from tissues of streptococcosis affected animals. The remaining 19 strains were isolated from tonsils of healthy carrier pigs. Suilysin gene specific sequence was detected in 79% of the strains tested. In isolates obtained from pigs with signs of streptococcosis this gene sequence was recorded in 85% of cases. In Streptococcus suis strains isolated from healthy carrier pigs the suilysin gene was detected in 63% of the isolates. It seems that suilysin toxic activity is only one of the many steps involved in the pathogenesis of Streptococcus suis infection and that strain's virulence cannot be stated only on the basis of suilysin gene sequence presence.

Abstract
Pulmonary hypertension (PH) is one the most fatal complications of systemic sclerosis (SSc). The aim of the present study was to investigate the occurrence of PH in SSc patients hospitalized in Department of Rheumatology and Internal Diseases University Hospital of Bialystok in years 2003-2004. PH was defined as pulmonary artery systolic pressure (PASP) higher than 35 mmHg as evaluated by ECHO-Doppler. We found PH in 23 out of 53 (43%) SSc patients included in the study. In the majority of patients 20/23 (87%) PH coexisted with the presence of scleroderma lung disease as evaluated by high resolution computed tomography of the lungs. In the remaining 3/23 (13%) patients isolated (arterial) PH was detected. Patients with isolated PH tend to have higher values of PASP (82 +/- 39.0 mmHg) than those with PH and interstitial lung disease (42.5 +/- 6.4 mmHg). The results of our study indicate that PH is a frequent complication of SSc.

Abstract
To investigate whether the biological toxicity of aquatic hypercapnia is due to the direct effects of CO2 or to the effects of acidification of seawater by CO2, the Japanese flounder (Paralichthys olivaceus) was subjected to seawater equilibrated with a gas mixture of air containing 5% CO2 (pH 6.18) or seawater acidified to the same pH with 1 N H2SO4. All the fish died within 72 h in the CO2 exposure group, whereas no mortality occurred in the acid group. Acid-base parameters as well as plasma ion concentrations were severely perturbed in the CO2 exposure group, whereas they were minimally affected in the acid group. These results clearly demonstrate that the mortality in the CO2 group is a direct result of the elevated levels of dissolved CO2 and not to the effects of the reduced water pH.

Abstract
A recently developed electronic nose has not yet been clinically applied to evaluations of oral malodor. This investigation sought to determine whether an electronic nose could clinically assess oral malodor. Twenty-nine healthy adults and 49 patients were assessed by results of an actual organoleptic test, a score representing malodor strength with an electronic nose in "top-note" mode (top-note score), and measurements of volatile sulfur compound (VSC) concentrations. The correlation coefficient between top-note and actual organoleptic scores (r = 0.71) was comparable with the log VSC and actual organoleptic scores (r = 0.63). However, the area under the receiver-operating characteristic plots for top-note score was significantly larger than that for log VSC. In logistic regression analyses with top-note score as a dependent variable, probing depth, tongue coating, and plaque control record each had independent associations. Our findings suggest that the top-note score from an electronic nose examination may be useful for the clinical evaluation of oral malodor.

Abstract
To compare the acute toxicity of CO(2)- and HCl-acidified seawater, eggs and larvae of a marine fish, Pagrus major, were exposed to seawater equilibrated with CO(2)-enriched gas mixtures (CO(2)=5% or 10%, O(2)=20.95% balanced with N(2)) or seawater acidified with 1 N HCl at two pH levels (pH 6.2 (=5% CO(2)) and 5.9 (=10% CO(2))) for 6 h (eggs) or 24 h (larvae). Mortalities of eggs were 85.8% (CO(2)) and 3.6% (HCl) at pH 6.2, and 97.4% (CO(2)) and 0.9% (HCl) at pH 5.9, while those of larvae were 61.2% (CO(2)) and 1.6% (HCl) at pH 6.2, and 100% (CO(2)) and 5.0% (HCl) at pH 5.9. Thus, previous research on the effects of acidified seawater on marine organisms, as a substitute for CO(2), has largely underestimated the toxic effects of CO(2).

Abstract
Ocean sequestration of CO2 is proposed as a possible measure to mitigate climate changes caused by increasing atmospheric concentrations of the gas, but its impact on the marine ecosystem is unknown. We investigated the acute lethal effect of CO2 during the early developmental stages of four marine teleosts: red sea bream (Pagrus major), Japanese whiting (Sillago japonica), Japanese flounder (Paralichthys olivaceus), and eastern little tuna (Euthynnus affinis). The percentages of larvae that hatched and survived were not affected by exposure to water with a PCO2 of 1.0 kPa (= 7.5 mmHg) within 24 h. Median lethal PCO2 values for a 360-min exposure were 1.4 kPa (cleavage), 5.1 kPa (embryo), 7.3 kPa (preflexion), 4.2 kPa (flexion), 4.6 kPa (postflexion), and 2.5 kPa (juvenile) for red sea bream; 2.4 kPa (cleavage), 4.9 kPa (embryo), 5.9 kPa (preflexion), 6.1 kPa (flexion), 4.1 kPa (postflexion), and 2.7 kPa (juvenile) for Japanese whiting; 2.8 kPa (cleavage) and > 7.0 kPa (young) for Japanese flounder; and 11.8 kPa (cleavage) for eastern little tuna. Red sea bream and Japanese whiting of all ontogenetic stages had similar susceptibilities to CO2: the most susceptible stages were cleavage and juvenile, whereas the most tolerant stages were preflexion and flexion.

Abstract
The cardiorespiratory responses were examined in yellowtail, Seriola quinqueradiata exposed to two levels of hypercapnia (seawater equilibrated with a gas mixture containing 1% CO(2) (water PCO(2) = 7 mmHg) or 5% CO(2) (38 mmHg)) for 72 hr at 20 degrees C. Mortality was 100% within 8 hr at 5% CO(2), while no fish died at 1% CO(2). No cardiovascular variables (cardiac output, Q; heart rate, HR; stroke volume, SV and arterial blood pressure, BP) significantly changed from pre-exposure values during exposure to 1% CO(2). Arterial CO(2) partial pressure (PaCO(2)) significantly increased (P < 0.05), reaching a new steady-state level after 3 hr. Arterial blood pH (pHa) decreased initially (P < 0.05), but was subsequently restored by elevation of plasma bicarbonate ([HCO(3)(-)]). Arterial O(2) partial pressure (PaO(2)), oxygen content (CaO(2)), and hematocrit (Hct) were maintained throughout the exposure period. In contrast, exposure to 5% CO(2) dramatically reduced Q (P < 0.05) through decreasing SV (P < 0.05), although HR did not change. BP was transiently elevated (P < 0.05), followed by a precipitous fall before death. The pHa was restored incompletely despite a significant increase in [HCO(3)(-)]. PaO(2) decreased only shortly before death, whereas CaO(2) kept elevated due to a large increase in Hct (P < 0.05). We tentatively conclude that cardiac failure is a primary physiological disorder that would lead to death of fish subjected to high environmental CO(2) pressures.

Abstract
In this investigation the Western blot test was treated as a method verifying results of the IFA, commercial ELISA and standardized ELISA tests (described in Part I). The verifying investigations were performed on 82 serum samples, which in the commercial ELISA were positive in 36 cases, dubious in 31 cases and negative in 15 cases as well as on 5 serum samples obtained from horses infected with Leptospira spp., which in the ELISA commercial were dubious (total of 87 sera samples). The antigens, against which the immunological response in horses was directed, were also established. The Milenia--Blot--Borrelia IgG test (MIDBO IgG-Kit 30 TESTS: DPC Bierman GmbH) was used in the investigation. In view of species differences, rabbit anti-horse IgG (whole molecule) alkaline phosphatase conjugate, no A6063 SIGMA-ALDRICH was used interchangeably. Also the control sera were substituted with the horse control sera. It was demonstrated that the Western blot test is the most reliable in the serological diagnosis of B. burgdorferi infection in horses. The commercial ELISA and standardized ELISA tests represent a lower diagnostic value than the Western blot test, although similar to each other, while the value of the IFA is minimal. In the Western blot test antigens were established against which the immunological response in horses in mostly directed. In the sera evaluated in this test as positive the presence of antibodies, mainly against antigens with the following molecular weights: 41 kDa, 62/60 kDa, 93 kDa, 72 kDa, 34 kDa (OspB), 66 kDa was noted. At the same time, antibodies contained in the sera accepted as negative, in 55.5% cases also reacted with the antigen of 41 kDa. It points to its minimal specificity. On the basis of the results obtained it is recommended that serological examination of horses should be with the ELISA and that positive or dubious results should be verified with the Western blot test.

Abstract
The investigations aimed to establish the reliability of the chosen serological tests designed for the diagnosis of Lyme borreliosis in horses. The investigations were carried out in five Horse Breeding Centres (OHK). Statistical analysis methods were used to determine sample size for particular centres: Krasne (Kr)--49, Łack (Ł)--21, Walewice (W)--111, BogusŁawice (B)--17, Kozienice (K)--61. The experimental material comprised the chosen horses from which blood samples were collected in order to obtain sera. The test used for indirect immunofluorescence assay (IFA No 75941, Bio-Mérieux) is commercially designed for the investigation of human sera and thus needed a prior species adaptation and standardization; ELISA (MRL DIAGNOSTICS, No EL0400G) which was also species adapted and stardandized and ELISA commercially assigned for the examination of dog or horse sera (Die System Diagnostica GmbH Borrelia burgdorferi Veterinary ELISA No. 122.00 Genzyme Virotech GmbH). In the IFA test the highest share of positive results was obtained in respect of the sera from OHK in (K)--60.7% and then in (B)--52.9%, (Ł)--42.9%, (W)--40.5%, (Kr)--38.7%. In the standardized ELISA the highest percent of positive results, amounting to 33.3%, was obtained in respect of the sera from (Ł), and then from (W)--20.7%, (K)--11.5%, (Kr)--10.2% and (B)--5.9%. The percent of positive results obtained in the commercial ELISA also agreement on a high level: the sera originating from (W) were positive in 18.9%, from (K)--9.8%, (Ł)--9.5%. (B)--5.9% and (Kr)--4.1%. Both ELISAs showed high agreement although the standardized test was characterized by a greater tendency for suggesting the presence of B. burgdorferi infection and the agreement of these two ELISAs with the IFA was not so strong. The IFA showed the highest tendency for suggesting the presence of the B. burgdorferi infection, being characterized by the highest percent of false positive results.

Abstract
The bison population in the Bialowieza Forest in Poland has now grown to approximately 300, while the herds in the Belarusian part of the forest total about 240 bison. The first signs of a health problem in these herds appeared in 1980, when two cases of balanoposthitis were detected in two bulls (2 and 5 years of age). Since 1980 research has been conducted to explain the cause of diseases, particularly balanoposthitis, and to monitor the health of bison in Bialowieza Forest. A total number of 614 bison (294 male and 320 female) of different ages was eliminated between 1980 and 2000. Not all the culled bison were examined (postmortem analysis, histopathological, bacteriological, virological and toxicological examinations, serological tests, molecular research). Based on the increase in numbers, reproduction in this population for the past 21 years is generally considered successful. Among 182 male bison eliminated during 1990-2000, only 85, or 47%, of the animals had balanoposthitis. Thus, the percentage of balanoposthitis cases went from 100% during the 1980s down to 47% in the past decade. It appears that the culling process has been a major factor leading to this decrease. It can be assumed that a set of factors is involved in the appearance of the disease (Corynebacterium spp., Bacillus sp., Pseudomonas aeruginosa, Escherichia coli, Ureoplasma spp, Fusobacterium necrophorum, Streptoccocus spp., Staphyloccocus spp.) while opportunistic infections including nematodes (Onchocerca spp.) are responsible for the occurrence of secondary lesions.

Abstract
Physiological and morphological differences between killifish adapted to seawater (SW) and fresh water (FW) were examined with special reference to chloride cells. There was no difference in plasma osmolality between SW- and FW-adapted fish, reflecting their euryhalinity. A rich population of chloride cells was detected in whole-mount preparations of the gills and opercular membrane from SW- and FW-adapted fish. There was no difference between SW- and FW-adapted fish in gill Na+,K+-ATPase activity or oxygen-consumption rates. The gill chloride cells were located mostly in a flat region of the afferent-vascular edge of the filaments. In both tissues, the cells were larger in FW- than in SW-adapted fish. The apical membrane of chloride cells was invaginated to form a pit in SW-adapted fish, whereas it was flat or showed projections and was equipped with microvilli in FW-adapted fish. Chloride cells often interdigitated with neighboring accessory cells in SW-adapted fish, forming multicellular complexes. In FW-adapted fish, on the other hand, a pair of chloride cells that were similar in size was occasionally associated to form "twin cells." Thus, distinct SW and FW types of chloride cells were defined. Our findings suggest that SW- and FW-type chloride cells are equally active in the two environments, but exhibit different ion-transporting functions.

Abstract
Laparoscopic intragastric resection of gastric leiomyoma was performed using needlescopic instruments. The patient was a 71-year-old man who had a 2-year history of gastric submucosal tumor 2 cm in diameter located near the esophagocardiac junction. After getting informed consent, we performed a laparoscopic intragastric tumor resection under an oral endoscope. There were no intra- or postoperative complications. The patient was discharged uneventfully. Histopathologic diagnosis of the tumor was leiomyoma. Laparoscopic intragastric resection of a benign gastric submucosal tumor using needlescopic instruments is technically feasible and as safe as a less invasive procedure.

Abstract
The aim of this study was answering the question whether cytofluorimetric determining of DNA ploidy, p53 and bcl-2 expression in tumour cells may enhance the diagnosis of squamous epithelial lung carcinoma. Samples of neoplastic tissue were taken from 11 operated patients. DNA staining was performed with propidium iodide. p53 and bcl-2 expression was evaluated by using monoclonal antibodies. By assessing of DNA ploidy we observed increased proliferative activity and, at the same time, high rate of the cell necrosis. In the analysis of p53 protein the presence of antigen was observed on average in 7.1 +/- 2.4, 15.1 +/- 3.9, and 19.8 +/- 4.1% of normal cells of the pulmonary tissue, the peripheral part of the tumour and cells of the central part of the tumour, respectively. bcl-2 was found on average in 7.3 +/- 2.2, 9.9 +/- 3.1, and 12.4 +/- 3.19% of the above cells, respectively. These results show that the technique of cytofluorimetric evaluation of p53 and bcl-2 proteins can be useful in diagnosis of pulmonary cancer in addition to classic histological and immunohistochemical methods.

Abstract
Epidemiological observations on the course and spread of equine influenza in Poland during the 1969 epizootic were carried out. The dynamics of the spread of the disease in the country are shown graphically by voivodship. The disease incidence and mortality rates for the entire country are also shown. The highest incidence of disease and mortality rates were found to be in November 1969. A/equi-2/Warsaw/69 was identified as the causal virus. It caused the largest epizootic in the country since 1954.
