Dogwood anthracnose, caused by Discula destructiva (1), is another new catastrophic tree disease that has ravaged natural populations of the flowering dogwood (Cornus florida) in the Appalachians over the past 15 years, and the epidemic is prognosticated to continue (2). An estimated 9.5 million acres have been affected, primarily in the Appalachian Mountains, from VA southwards, alone, and an estimated 50% of all dogwoods in PA have been killed. Since acid deposition has been linked experimentally with disease induction, and since the disease incidence and severity are more pronounced at higher elevations where lower pH precipitation events occur, we investigated the effect of acidic foliar sprays on moiphologic changes in the foliar cuticle and trichomes (3), the initial sites of infection and foci of Discula sporulation.

In the literature review the authors present an analysis of the current stateproblem of ovarian cancer and ways of its possible solution. According to clinicalobservations and conducted in recent decades by morphological,immunohistochemical and molecular genetic studies it is fairly proved that theprimary cause of serous ovarian cancer is the pathology of the mucous layer offallopian tube. In the fallopian tube as a result of ciculation of inflammation andcarcinogens elements arises dysplasia of the mucosa with the development of thepreinvasive and initial invasive carcinoma with subsequent damage of the ovariesand pelvic peritoneum. Retrospective studies of a significant number of women’shealth status who had a deligation or removal of fallopian tubes in previous years showed a decrease in the disease incidence of serous ovarian cancer from 30 to 90%. The conclusions about the possibility of preventive measures of ovariancancer by opportunistic salpingectomy at post-productive age are made. In many world countries (Canada, China, France, Italy, Austria) the introduction of such a method of prevention has been started. We believe that in Ukraine there is an urgent need and all possibilities to solve this problem. Key words: ovarian cancer, preventive measures, opportunistic salpingectomy.

SummaryEnhancement of the resistance level in plants by rhizobacteria has been proven in several pathosystems. This study investigated the ability of four rhizobacteria strains (Pseudomonas putida BTP1 and Bacillus subtilis Bs2500, Bs2504 and Bs2508) to promote the growth in three barley genotypes and protect them against Cochliobolus sativus. Our results demonstrated that all tested rhizobacteria strains had a protective effect on barley genotypes Arabi Abiad, Banteng and WI2291. However, P. putida BTP1 and B. subtilis Bs2508 strains were the most effective as they reduced disease incidence by 53 and 38% (mean effect), respectively. On the other hand, there were significant differences among the rhizobacteria-treated genotypes on plant growth parameters, such as wet weight, dry weight, plant height and number of leaves. Pseudomonas putida BTP1 strain was the most effective as it significantly increased plant growth by 15-32%. In addition, the susceptible genotypes Arabi Abiad and WI2291 were the most responsive to rhizobacteria. This means that these genotypes have a high potential for increase of their resistance against the pathogen and enhancement of plant growth after the application of rhizobacteria. Consequently, barley seed treatment with the tested rhizobacteria could be considered as an effective biocontrol method against C. sativus.

Relevance. The importance of studying and analyzing contribution of occupational risk factors in musculoskeletal disorders among emergency medical personnel is related to high disease incidence rates and work specifics. The objective of our research envisaged formalization of information obtained for the analysis and assessment of occupational risks of developing musculoskeletal and connective tissue disorders in ambulance personnel. Results. According to professional medical examination results, musculoskeletal and connective tissue disorders ranked second among all diagnosed diseases. The relative risk of developing those disorders was 70% indicating the link between them and transport vibration (category 1) affecting the backbone during long trips in ambulance cars.

Quality Water

Epidemiological studies in rural Mexico have shown the role of poor quality water in gastrointestinal disease incidence. This led to the establishment of a program, which included the assessment of inexpensive systems for household treatment of drinking water. We describe the main features of a hand carved stone filter evaluated over 6 months under laboratory conditions and 6 months under household conditions. The filter had a capacity of 5L and an average volume of 18L/d filtered water (the temperature of which was always an average 4°C lower than the influent). Average bacterial removals under laboratory conditions were 98% for total and faecal coliforms (TC, FC), 96% for faecal streptococci (FS), 99% for Pseudomonas aeruginosa and 100% for helminth eggs and protozoan cysts. During the field evaluation removals were 80–100% TC, 45–95% FC and 8–93% FS due to the different qualities of influent water and the operation conditions. Nevertheless, the filters represented an immediate mitigation measure of the health risks associated with the continuous ingestion of microbiologically unsafe waters.

Introdução: A osteoporose é considerada um grave problema de saúde pública em todo o mundo. No Brasil ainda não há dados estatísticos sobre a real incidência desta doença. Os glicocorticóides representam uma classe de drogas muito usada, sendo que podem influenciar significativamente a massa óssea. Entretanto, após tratamento com glicocorticóides em ratos, esses podem ou não apresentar alterações na massa óssea. Objetivo: Avaliar a eficácia da administração de dexametasona ou metilprednisolona em produzir osteoporose em ratas. Métodos: Vinte e quatro ratas, oriundas do biotério da Faculdade de Medicina de Itajubá, foram utilizadas e divididas em três grupos: controle, metilprednisolona e dexametasona. Foram avaliados íons e proteínas totais sanguíneos e feita a análise histopatológica de tecido ósseo. Resultados e conclusão: Pela análise histológica da espessura trabecular óssea, houve redução da massa óssea dos grupos tratados com glicocorticóides em comparação com o grupo controle, evidenciando o sucesso da indução de osteoporose. Além disso, houve uma maior redução da massa óssea no grupo tratado com dexametasona, em comparação com o grupo tratado com metilprednisolona. A análise bioquímica de cálcio, fósforo, magnésio e proteínas totais não sofreram diferença significativa entres os grupos, não sendo um bom marcador para remodelamento ósseo e para diagnóstico de osteoporose.Evaluating the Effectiveness of Dexamethasone or Methylprednisolone to Produce Osteoporosis in RatsIntroduction: Osteoporosis is considered a serious public health problem in worldwide. In Brazil we do not have statistics on the real disease incidence. Glucocorticoids are a class of drugs widely used, and can significantly influence bone mass. However, after treatment with glucocorticoids in rats, these may or may not show changes in bone mass. Objective: Evaluating the effectiveness of dexamethasone or methylprednisolone to produce osteoporosis in rats. Methods: Twenty-four rats, originated from the vivarium of the Faculty of Medicine Itajubá were used and divided into three groups: control, methylprednisolone and dexamethasone. Ions was evaluated blood and histopathology of bone tissue. Results and conclusion: by histologic analysis of trabecular bone thickness, a reduction of the mass bone in the groups treated with glucocorticoids compared with the group control, demonstrating the successful induction of osteoporosis. Furthermore, there was a greater reduction in bone mass in the group treated with dexamethasone compared with the group treated with methylprednisolone. The analysis biochemistry of calcium, phosphorus, magnesium and total protein did not undergo significant difference among the groups, there is a good marker for bone remodeling and osteoporosis diagnosis.
