Muğla orijinli sarı kantaron (Hypericum perforatum L.) populasyonlarınıın bazı agronomik ve kalite özelliklerinin belirlenmesi

Muğla iline bağlı yedi lokasyondan toplanan tohumlar ile Bornova ekolojik koşullarında yetiştirilen 160 adet sarı kantaron (Hypericum perforatum L.) tek bitkilerinin agronomik ve kalite özelliklerini belirlemeyi amaçlayan bu çalışmada, bitki boyu, yeşil herba verimi, üst yeşil herba verimi, alt yeşil herba verimi, üst drog herba verimi, alt drog herba verimi ve hypericin oranları belirlenmiştir. Daha sonra elde edilen bu veriler, istatistiki analize tabi tutulmuş, minimum, maksimum, ortalama, varyans, standart sapma, Sx ve Cv değerleri hesaplanmış, frekans dağılım tabloları çıkarılmıştır. Populasyonda Hypericum perforatum L. Bitkisi için önemli iki özellikten biri olan üst drog herba verimi minimum 4 g/bitki, maksimum 125 g/bitki, ortalama 30.7 g/bitki olarak belirlenmiştir. Hypericin oranı ise, 154 bitkide saptanmış, minimum %0.132, maksimum %0.308, ortalama ise % 0.267 olarak elde edilmiştir. Üst drog herba verimi en yüksek Fethiye Bağlıağaç Köyü-Alagöz Mahallesi lokasyonunda ölçülmüştür. Hypericin oranı ortalaması en yüksek olan lokasyonun ise, Muğla-Marmaris Yolu lokasyonu olduğu sonucuna varılmıştır

The effect of COVID-19 on development of hair and nail disorders: a Turkish multicenter, controlled study

© 2022 the International Society of Dermatology.Background: A broad spectrum of skin diseases, including hair and nails, can be directly or indirectly triggered by COVID-19. It is aimed to examine the type and frequency of hair and nail disorders after COVID-19 infection. Methods: This is a multicenter study conducted on consecutive 2171 post-COVID-19 patients. Patients who developed hair and nail disorders and did not develop hair and nail disorders were recruited as subject and control groups. The type and frequency of hair and nail disorders were examined. Results: The rate of the previous admission in hospital due to COVID-19 was statistically significantly more common in patients who developed hair loss after getting infected with COVID-19 (P < 0.001). Telogen effluvium (85%) was the most common hair loss type followed by worsening of androgenetic alopecia (7%) after COVID-19 infection. The mean stress scores during and after getting infected with COVID-19 were 6.88 ± 2.77 and 3.64 ± 3.04, respectively, in the hair loss group and were 5.77 ± 3.18 and 2.81 ± 2.84, respectively, in the control group (P < 0.001, P < 0.001). The frequency of recurrent COVID-19 was statistically significantly higher in men with severe androgenetic alopecia (Grades 4–7 HNS) (P = 0.012; Odds ratio: 2.931 [1.222–7.027]). The most common nail disorders were leukonychia, onycholysis, Beau's lines, onychomadesis, and onychoschisis, respectively. The symptoms of COVID-19 were statistically significantly more common in patients having nail disorders after getting infected with COVID-19 when compared to the control group (P < 0.05). Conclusion: The development of both nail and hair disorders after COVID-19 seems to be related to a history of severe COVID-19
