Plant Essential Oils Used Against Some Bee Diseases

The most common honey bee diseases are American foulbrood (AFB) caused by the bacterium Paenibacillus larvae, Chalkbrood caused by fungus Ascosphaera apis and diseases caused by parasitic mites such as Acarapis woodi, Varroa destructor. These diseases and pests not only cause economic loss but also cause ecological problems related to the role of honey bees, as the most important pollinators on Earth. Synthetic acaricides and antibiotics are used to keep the diseases and mites in control. Use of the drugs lead to the development of drug-resistant organisms, detrimental effect on non-target organisms and the residue problem in bee products. For this reasons, the need for alternative control methods has become compulsory in recent years. It has been known that some plant oils used widely in perfumery and food industry for flavor and smell have been used as repellent to certain insects, bactericide and fungicide. Therefore, intensive studies have been carried out on plants with anti-mites, antibacterial and antifungal potentials and these studies are still going on. Recently, studies in this area have shown that essential oils of plants such as thyme, cloves, mint, lemon grass, cinnamon, grapefruit, rosemary, marigold, are lethal to some mites, bacteria and fungi. In addition, it has been reported that some components, isolated from these plants such as sanguinarine, thymoquinone, capsaicin, carvacrol, citral, eugenol, thymol, show these effects on the organisms. As a result, in countries rich in biodiversity due to endemic plant species, the essential oils used in control of these diseases should be favored instead of or in combination with conventional drugs in integrated the disease management programs because of the lack of harmful effects of essential oils on non-target organisms and environment

Knowledge, Attitude and Behavior Levels about Osteoporosis among 18-35 Years Old Women

Objective: Osteoporosis (OP) which is a global health problem can be prevented or the development of the disease can be delayed. To educate individuals at risk and to intervene in a timely manner will provide significant reduction in morbidity and mortality caused by OP. Possible interventions in the age group of developed OP are important to determine. Therefore, in this study, it was aimed to determine information, attitudes and behaviors levels on osteoporosis at young women. Materials and Methods: This study was carried out among 18-35 years old females who attended to outpatient clinics of Dışkapı Yıldırım Beyazıt Training and Research Hospital Family Medicine Clinic. A questionnaire was used to assess knowledge, beliefs, and practices towards OP. The questionnaire to assess practices related to OP included questions on positive and negative behaviors towards OP. The positive behaviors assessed were dietary calcium intake, physical activity and exposure to sun. The negative behavior assessed was on smoking status. Results: A total of 218 women (mean age= 26.2±5.6 years) were enrolled in the study. The median score of knowledge about OP was 40, out of a total score of 100. Knowledge scores were lower than the median in 138 (63.3%) and were higher than the median in 80 (36.7%) of the participants. In the group who had high knowledge score than median (n=80); 24 (30%) were smokers, 8 (10%) were not exposed to the sun for at least 10 minutes a day and 45 (56.2%) of the participants did not achieve the recommended daily allowances for calcium and 64 (80%) were not engaged in the recommended exercises in type and duration. Conclusion: Awareness for OP is low in young women and practices towards preventing OP are inadequate. Thus, preventive measures are required in order to encourage OP-preventive life style especially before reaching peak bone mass
