Abstract
The effect of traffic on the content of lead and cadmium in grass morphological parts-leaves, shoots, and inflorescences-was studied. The samples were taken on a part of the European route E30 (Siedlce by road). The following plants were tested: Dactylis glomerata, Arrhenatherum elatius, and Alopecurus pratensis. During the flowering of grasses, the plant material was collected at distances of 1, 5, 10, and 15 m from the edge of the road, on the strip of road with a length of 9 km. In the collected plant parts, the content of lead and cadmium using the atomic absorption spectroscopy (AAS) method was determined. The effect of distance from the road on the content of lead and cadmium was evaluated using regression equations. Average lead content in the above parts of tested grass species was 3.56, while cadmium 0.307 mg kg(-1) dry matter (DM). Lead content in plants of Alopecurus pratensis (average 4.11 mg kg(-1) DM) was significantly higher than in other grasses. The lowest cadmium content, significantly different from the other species, was found in plants of Arrhenatherum elatius (0.251 mg kg(-1) DM). Distance of sampling sites from the roadway significantly affects the differences in the content of cadmium and lead in plants. Analyzed aboveground plant organs of studied grasses were significantly different in contents of lead and cadmium. There were species differences in the proportions of cadmium concentration in various organs of plants. The obtained results indicate the possibility of species composition selection of grassland sward in areas with a higher risk of heavy metals associated with dust sedimentation.

Abstract
Great progress has been achieved over the last years in studies on chromosome arrangement in mammalian cell nuclei. Growing evidence indicates that the genome's spatial organization is of functional relevance. So far, no attention has been paid to the nuclear organization of B chromosomes (Bs). In this study we have examined nuclear positioning of Bs in 2 species from the Canidae family--the red fox and the Chinese raccoon dog. Using 2D and 3D fluorescence in situ hybridization and 2 gene-specific probes (C-KIT and PDGFRA), we analyzed the location of Bs in fibroblast nuclei. We found that small Bs of the red fox occupied mostly the interior of the nucleus, while medium-sized Bs of the Chinese raccoon dog were observed in the peripheral area of the nucleus as well as in intermediate and interior locations. The more uniform distribution of B chromosomes in the Chinese raccoon dog may be the result of differences in their size, since 3 morphological types of Bs are distinguished in this species. Our results indicate that 3D positioning of B chromosomes in fibroblast nuclei of the 2 canid species is in agreement with the chromosome size-dependent theory.

Abstract
An AI Ayrshire bull was subjected to cytogenetic examination due to lowered fertility. Preliminary Giemsa staining revealed a normal chromosome complement (60,XY) and G-banding did not allow us to draw a clear conclusion concerning an occurrence of chromosome rearrangement. Testicles were collected at slaughter and synaptonemal complex (SC) analysis revealed a large cross-shaped tetravalent configuration in pachytene spreads. No association between the tetravalent and XY bivalent was observed. Chromosome painting, with the use of bovine whole chromosome painting probes, conjugated with DAPI staining, facilitated a detailed description of the translocation rcp(2;4)(q45;q34). This study shows that post mortem analysis of synaptonemal complexes is a simple and useful tool for the preliminary detection of reciprocal translocation carriers.

Abstract
We conducted a cytogenetic study of bovine parthenotes derived from oocytes matured and cultured in vitro. In vitro maturation was carried out by culturing follicular oocytes for 24 h in TCM199 supplemented with estrous cow serum (ECS) and hormones at 39 degrees C in 5% CO2. Matured oocytes were incubated for 20 h in sperm TALP without the addition of spermatozoa, after which they were cultured in maturation droplets for 48 to 72 h. Spontaneous activation occurred in 9.5% of the matured oocytes. Cytogenetic analysis of 24 parthenotes revealed that 62.5% exhibited a normal, diploid chromosome complement. The remaining 37.5% had various ploidy anomalies: haploidy (25%), triploidy (4.2%) and tetraploidy (8.3%). Parthenotes exhibited different developmental stages. The number of blastomeres ranged from 2 to 8 within a parthenote. Only 1 parthenote was comprised 9 to 16 cells. The results showed that spontaneous parthenogenetic activation which occurs in an IVM/IVF system may interfere with embryo production efficiency.

Abstract
PURPOSE Experimental effort focused on the growth inhibition of an androgen-resistant prostatic carcinoma, using pharmacological inhibition of protein kinase C (PKC) as the therapeutic target. MATERIALS AND METHODS Studies were performed in cell culture using the Pollard (PA) III androgen-insensitive spontaneous rat prostate tumor cells, and the human prostate tumor lines, PC-3 and LnCaP. Pharmacological agents included steroid hormones and PKC modulators; measured parameters of tumor growth/function included cell number, PKC activity and sphingolipid metabolism. RESULTS Triamcinolone (TA) and sphinganine synergized to inhibit the proliferation rate of PA III prostate tumor cells by converging through separate mechanisms to inhibit protein kinase C. At five days of cell culture, 0.1 microM TA reduced both the soluble and particulate forms of PKC in association with a 35-40% reduction in cellular proliferation. Exogenous sphinganine, a competitive inhibitor at the regulatory domain of PKC had no anti-proliferative effect at 1 microM, but in combination with TA synergized to reduce proliferation 80-90%, three days in advance of any detectable inhibitory effect of TA alone on cell number. TA produced no discernable stimulation of endogenous free sphingosine production as evidenced by the lack of an effect on the activity of neutral membrane sphingomyelinase or in the turnover of total cellular sphingomyelin. Phorbol esters, but not cell permeable diglycerides, prevented the TA + sphinganine effect suggesting that a stable long term PKC activation was required for reversal. Steroid specificity studies of the synergistic response revealed that while other glucocorticoids mimicked TA, aldosterone was less active and representatives of the three major classes of sex steroids were inert. Tests of sphinganine specificity demonstrated that calphostin C, a chemically unrelated inhibitor of the regulatory site of PKC, also produced a supra-additive interaction with TA. Ceramides (C2 & C6), which were closely related chemically to sphinganine but lacked affinity for the regulatory subunit of PKC, were inactive in this system. Analyses of the cellular specificity of the TA-sphinganine synergism using the human prostate carcinoma cell lines PC-3 and LnCap revealed a true synergistic growth inhibition in the glucocorticoid receptor positive PC-3 line and no significant interaction in the glucocorticoid receptor negative LnCap cells. CONCLUSIONS TA-induced reduction of PKC concentration coupled with sphinganine antagonism of PKC activation contributed to in a synergistic growth inhibition of an androgen resistant prostatic carcinoma.

Abstract
This paper presents the results of recovering horse oocytes by aspiration and maturation in vitro for 24, 30, 36 or 42 h. A total of 522 oocytes were recovered from 221 ovaries (2.4 per ovary) and 271 oocytes (51.9%) were selected for in vitro maturation (IVM). Oocytes were cultured in maturation medium (TCM 199 + estrus cow serum [ECS] + follicle-stimulating hormone [FSH] + 17 beta-estradiol + gentamycin). One hundred and seventy oocytes were cytogenetically analysed (68.3%). Cytogenetic analysis showed that the stage of maturation (first telophase-TI or second metaphase-MII) for fertilization was achieved in 42.2% of oocytes after 24 h, 70.4% of oocytes after 30 h, 75.0% of oocytes after 36 h and 74.4% of oocytes after 42 h of in vitro maturation.

Abstract
OBJECTIVE To examine selection criteria for ovarian reserve screening. DESIGN Retrospective study. PATIENTS Two hundred nineteen women underwent testing for ovarian reserve for woman's age > 35 years, any age with unexplained infertility, one ovary, or a poor response to hMG. INTERVENTIONS Clomiphene citrate challenge test. MAIN OUTCOME MEASURES Frequency of abnormal ovarian reserve screening, menstrual cycle parameters, response to hMG, and pregnancy outcome by screening criteria. RESULTS One hundred eighty-four (84.0%) women had a normal ovarian reserve screening test; 35 (16.0%) had an abnormal ovarian reserve screening test. Twenty-six had abnormal ovarian reserve screening when screened by age, 14 for unexplained infertility, 5 for poor response to hMG, and 6 for one ovary. Fifteen women with abnormal ovarian reserve screening had more than one indication for screening. For women attempting pregnancy (n = 182), 49 of 148 (33.1%) with normal ovarian reserve screening became pregnant compared with 2 of 34 (5.9%) with abnormal ovarian reserve screening. Within each screening category, women with abnormal ovarian reserve had menstrual cycle parameters associated with a short follicular phase, required more hMG, and responded poorly to hMG. CONCLUSIONS One of six women undergoing ovarian reserve screening had an abnormal test, which was associated a poor reproductive outcome. Age was the most important single criteria. Selected ovarian reserve screening is simple and inexpensive and should be offered to all fertility patients meeting the specific screening criteria listed above.

Abstract
Oocytes were collected after slaughter by aspiration from pairs of ovaries of individual donors. A total of 656 oocytes was selected for IVM from 74 pairs of ovaries (8.9 oocytes per pair, ranging between 1 and 25). The oocytes were matured in droplets of maturation medium (TCM-199 medium supplemented with 20% estrous cow serum (ECS), 50 microg/ml gentamycin, 10 microg/ml FSH, 1 microg/ml estradiol-17beta). Cytogenetic analysis of 348 oocytes showed 79 at the first metaphase (MI; 22.7%, 79 348 ), 11 at the first telophase (TI; 3.2%, 11/348 ), and 258 at the second metaphase (MII; 74.1% 258/348 ). Significant differences (P < 0.01) were shown among the donors regarding the number of oocytes selected for IVM and the number of oocytes matured for IVF.

Abstract
BCG immunotherapy is very effective in the treatment of superficial transitional cell carcinoma of the bladder, but its significant toxicity may limit its use in some patients. In an effort to find less toxic and potentially more effective treatments we investigated the possible immunotherapeutic potential of combinations of Alpha Interferon (1000 IU) and Gamma Interferon (500 IU) with bacillus Calmette Guerin (BCG) (10(7) cfu), Interleukin-2 (4000 IU), and Keyhole Limpet Hemocyanin (50 micrograms.) in the MBT2 murine bladder cancer model. Significant reductions (p less than 0.05) in tumor incidence relative to the saline control, 83%, Day 35) was observed in groups receiving alpha interferon (42%), Keyhole limpet hemocyanin (42%), interleukin-2 (25%), alpha interferon + Keyhole limpet hemocyanin (17%), alpha interferon + interleukin-2 (33%), gamma interferon + BCG (42%), and gamma interferon + interleukin-2 (17%). All treatment groups with the exception of the group receiving gamma interferon had significantly reduced tumor volume (p less than 0.05) relative to the saline control. Combination treatment groups were significantly more effective than single agent treatments (p = 0.0057). The exhibited anti-tumor effect of these immunotherapeutic agents alone and in combination suggest that they may prove to be effective forms of immunotherapy for transitional cell carcinoma of the bladder.

Abstract
The introduction of extracorporeal shock wave lithotripsy (ESWL) has provided an avenue for dealing with many urinary stones noninvasively. The margin of safety for the kidney during shock wave administration is largely undefined. A pilot study was performed where six kidneys in five female mongrel dogs were shocked. Group A kidneys were given 1,776, 4,500, 6,000, or 8,000 shocks, respectively, at 18-24 kV. Group B kidneys received 1,600 and 8,000 shocks (18-24 kV). The number of shocks per electrode ranged from 500 to 4,538 and averaged 2,490. The dogs were sacrificed forty-eight to seventy-two hours (Group A) or twenty-eight to thirty-two days (Group B) post-treatment. Modest damage (hematoma and/or interstitial hemorrhage) was noted in all kidneys. Evidence of permanent change (fibrosis) was noted in both Group B kidneys. Complete necrosis of the kidney was not seen after administration of 8,000 shocks. These preliminary data indicate that lithotripsy can, in some circumstances, produce renal damage in the canine model.
