Gerbera Çiçeklerinin Vazo Ömrü Üzerinde Ceviz Çayı ve Mikrokapsüle Emdirilmiş Lavanta Yağının Etkisi

In the study, it was aimed to increase the vase life of Basic, Ulaş and Terra Ozan cultivars of Gerbera sp. For this purpose, microcapsules containing lavender oil (1000 and 1500 ppm) and naturally obtained walnut tea (33% and 50%) were used. Sucrose (4%) was added to all vase solutions, including the control group solutions. The experiment was set up with 3 replications (three vases) for each treatment and one flower per replication. As a result of the experiment, it was observed that both walnut tea and lavender treatments did not cause a significant change in the vase life of the Terra Ozan cultivars. In the Basic cultivar, the vase life of the flowers in the solution containing lavender oil was longer than that in the solution containing walnut tea, but both treatments did not make a significant difference compared to the control. In Ulaş, both walnut tea and lavender oil applications caused significant increases in the vase life of the flowers. The applications made in the study caused significant changes in the water intake of the flower stems. The treatments that increase the water intake also increased the vase life.

ENCAPSULATION LAVENDER OIL BY SPRAY DRYING FOR SPORTSWEAR

Microencapsulation technology has been increasingly used in textile industry due to give some peculiarities such as controlled released etc. In this study we aim to make aromatherapy sportswear using lavender oil. Lavender oil is encapsulated by different wall materials. Microcapsules were obtained by spray drying method. Differential scanning calorimetry, thermal gravimetric analysis, Fourier Transform infrared spectroscopy, morphological analyses were applied to microcapsules. Optimum microcapsules were applied to different fabrics. Fastness to washing and rubbing, SEM and antibacterial tests were carried out.

Effects of Essential Oils on in Vitro Growth of Fungi Cladobotryum dendroides and Mycogone perniciosa Infecting Button Mushroom

The aim of the studies was to investigate the effect of camel grass, lavender, patchouli, peppermint and tea tree essential oils, and their mixtures on the in vitro growth of pathogenic fungi Cladobotryum dendroides and Mycogone perniciosa, occurring in the cultivation of button mushroom (Agaricus bisporus). The mycelial growth of the tested pathogens was evaluated on PDA medium. Essential oils were added in three doses: 0.25; 0.5 and 1 mg·cm–3 of PDA medium. Camel grass and peppermint essential oils applied at the highest dose inhibited completely the in vitro growth of C. dendroides mycelium. Lavender oil used at the amount of 1 mg·cm–3 reduced the growth of the pathogen by 90 %. In the case of M. perniciosa the complete inhibition of the pathogen’s growth was observed after the addition of camel grass oil to PDA medium, irrespective of a dose, and lavender oil at the doses of 0.5 and 1 mg·cm–3. The efficacy of the tested mixtures against M. perniciosa was high. Generally, all mixtures of essential oils, irrespective of a dose, completely controlled the growth of the pathogen. The complete inhibition of the growth of C. dendroides was observed only on the medium with the addition of the mixture of camel grass and peppermint oils at the highest dose. The conducted research showed that natural essential oils due to their antifungal properties could be useful in the Integrated Disease Management for the protection of button mushroom against diseases. They could be an effective alternative to synthetic chemical fungicides.

Effect of inhaler and topical lavender oil on pain management of arteriovenous fistula cannulation

Background: The recurrent arteriovenous fistula (AVF) intervention in the treatment of hemodialysis induces pain in patients. Lavender oil has analgesic, antimicrobial, and calming effects. This oil is widely used in patients to reduce anxiety and stress associated with pain caused by analgesics. Method: The present study is a randomized controlled and experimental clinical trial in which patients ( n = 90) who underwent hemodialysis with AVFs were randomly divided into three groups. The intensity of pain was measured in all patients at three different stages during the insertion of arterial needles for hemodialysis: (1) The topical application of 100% lavender essential oil, (2) the inhaler application of 100% lavender essential oil, and (3) no intervention. The placebo (water) was applied to groups 1 and 2. Results: Our findings revealed that the mean pre-application pain scores in hemodialysis patients were 57.58 ± 20.28 in the working group, 48.53 ± 20.23 in the control group, 19.49 ± 15.66 in the post-application group, and 45.33 ± 25.52 in the control group ( p < 0.005). The average pain scores after the application of lavender oil were 22.66 ± 15.35 in the inhaler lavender group, 16.33 ± 15.97 in the topical lavender group, and 45.33 ± 25.52 in the control group. Conclusions: After inhaler and topical application of lavender oil, a significant decrease in the severity of pain was recorded for patients at the time of arterial insertion of needles.
