Prevalence of Becker Nevus in Young Men

Background and Design: Becker nevus (BN), characterized by sharply and irregularly bordered, unilaterally localized, hyperpigmented macules and patches which can go along with hypertrichosis, is a kind of hamartomatous lesion that predominantly affects males 4-6 times more frequently than females. It is usually seen in peripubertal period. There are scarce epidemiological data on BN and the prevalence in our country is also unknown. In this prospective, cross-sectional study, we aimed to determine the prevalence of BN among young adult males in Turkey.Materials and Methods: 8207 male candidates from different regions of Turkey who would be selected as a student in a governmental school and were referred to the dermatology outpatient clinic between March 2012 and August 2012, were included in our study. In addition to comprehensive medical examination, candidates were also inspected for the presence of BN, its localization, the asociation with hypertrichosis, and the findings were recorded.Results: The mean age of the candidates was 20.02±1.40 (range: 18-22) years and the mean age at BN onset was 12.2. BN was detected in 68 out of 8207 candidates (two different localizations in one subject). The prevalence of BN was calculated as 0.82%. The distribution of BN localization was as follows: mostly on the pectoral region ( 24.64%), and in decreasing order, on the scapular region (23.18%), shoulder (18.84%), infrascapular region (17.39%), arm (5.80%), abdomen (5.80%) and the thigh (4.35%). Hypertrichosis was present on 34 out of 69 BN (49.2%) that were found in 68 subjects.Conclusion: In our study, it was determined that BN was mainly localized on the pectoral and scapular regions, the prevalence was 0.82% and, 49,2% of the lesions were hypertrichotic

PHENOLOGICAL BEHAVIOURS OF THE LOCAL ENDEMIC Paeonia mascula (L.) Mill. subsp. bodurii Özhatay IN ÇANAKKALE, TURKEY

DergiPark: 974130trkjnatBu araştırma, lokal endemik Paeonia mascula (L.) Mill. subsp. bodurii Özhatay’ın yaşam döngüsü içerisindeki fenolojik davranışlarının gözlemlenmesini, kaydedilmesini ve yorumlanmasını kapsamaktadır. Fenolojik gözlemler çoğunlukla kültür bitkileri üzerinde uygulanmakla birlikte, endemik bir taksonunun üzerinde yapılan bu çalışmadan elde edilen veriler, koruma eylem planı hazırlanmasında önemli bir kaynak oluşturmaktadır. Geofit olan bitkinin toprak üstünde geçirdiği fenolojik döngü süresi ortalama 206 gün olarak tespit edilirken, kış aylarını toprak altında ortalama 159 gün olarak dormanside geçirmektedir. Doğal habitatlarında daha düşük rakımlarda bulunan populasyonların yüksek rakımlarda yetişenlere göre çiçeklenme, meyve oluşturma ve tohum olgunlaşması gibi evrelere nispeten daha erken bir dönemde girdiği ve bu fenofazlarda daha uzun süreli kaldığı belirlenmiştir. Fenofaz sürelerinin, başlangıç-bitişlerinde fark olmasına rağmen toplam yaşam döngüsünün aşağı yukarı aynı olduğu görülmüştür.This study covers the observation, recording and interpretation of the phenological behaviour of the local endemic Paeonia mascula (L.) Mill. subsp. bodurii Özhatay in its life cycle. Although phenological observations are mostly applied on cultivated plants, the data obtained from this study on an endemic taxon constitute an important resource for the preparation of a conservation action plan. While the phenological cycle time of the geophyte plant on the ground is determined as 206 days on average, it spends the winter months in dormancy with an average of 159 days underground. It was determined that the populations at lower altitudes in their natural habitats entered the flowering, fruit formation and seed maturation stages relatively earlier than those grown at higher altitudes and remained in these phenophases for longer periods. The total life cycle was more or less the same, although there were differences in phenophases durations and beginnings-ends.

Relationship Between Atopy Patch Test with Foods and SCORAD

Background and Design: The relationship between food and atopic dermatitis (AD) is controversial. Atopy patch test (APT) gained prominence due to low specificity of “fresh prick tests” (FPT) with foods, commonly late occurrence of lesions in AD and, thus, the inconsistencies in anamneses, and being the provocative tests time consuming and risky, as well as due to the role of T lymphocytes in the pathophysiology of the disease. In this study, we investigated the relationship of APT and FPT made with food with SCORAD index assessing the disease severity.Materials and Methods: Forty-five children (21 males and 24 females) aged between 2-15 years who were diagnosed with AD in our outpatient clinic between May 2006 and May 2007 were included in the study. FPT and APT with eggs, milk and wheat flour were performed in all patients. The severity of illness was assessed using the SCORAD index. Statistical analysis was performed using SPSS version 11.0 for Windows. A p value of less than 0.05 was considered statistically significant

Taxonomic revision of the genus Psathyrostachys Nevski (Poaceae: Triticeae) in Turkey

In this study, the genus Psathyrostachys Nevski is revised in Turkey. Furthermore multivariate analysis have been carried out in order to understand the delimitation of the taxa of Psathyrostachys. For this reason, 20 quantitative, qualitative and multi-state morphological characters were scored for the accessions representing 10 populations of the genus. The data were subjected to numerical taxonomic analysis. The results showed that the genus is represented by 3 species one of which is new species and the other one is a new record for Turkey. An account of 3 species and 4 subspecies recognized in the genus is given including the genus description, a key for the species as well as the subspecies, species descriptions, flowering times, habitats, altitudes, type citations, distributions, phytogeography and their conservation status.

ANTIOXIDANT, ANTIMICROBIAL AND ANTITUMORAL EFFECTS OF STACHYS ANNUA (L.) L. SUBSP. ANNUA VAR. ANNUA IN COMPARATIVE CANCER PROFILES

The genus Stachys (Lamiaceae) have been used for the treatment of folk medicine. This study was carried out with an objective to investigate the in vitro antimicrobial, antioxidant and antitumor effects of leaves of Stachys annua subsp. annua var. annua. The antimicrobial activity of ethanol extract (75µL) of leaves of S. annua subsp. annua var. annua was evaluated for potential antimicrobial activity against some bacterial and fungal isolates obtained from hospital. Antimicrobial susceptibility testing was determined with using the disc diffusion method according to the protocol applied by CLSI. The results showed that the ethanol extract revealed similarly effect against bacteria as compared to standart antibiotics. But, the extract showed slightly effect against Candida species. Also, we used HeLa and PC3 cells to test anticancerogen effect on urinary system. The cells were cultured for ATCC protocol. After application of extract dilution, we analyzed MTT assay for viability detection at 570 nm. Based on cytotoxicity value, optimal concentration were evaluated at 50uM. The potency of cell growth inhibition for each extract was expressed as IC50 value. According to datas, we showed that antioxidant activity of this plant have significantly increased. Stachys annua (L.) L. subsp. annua var. annua may evaluated in advanced pharmacological studies for distinct feature

Antimicrobial Activity of Centaura derderiifolia, Stachys aleurites and Anthemis aciphylla

The antimicrobial activity of the ethanol, aseton, ethyl asetate and chloroform extracts from Centaurea derderiifolia Wagenitz (Asteraceae) , Stachys aleurites Boiss. (Lamiaceae) and Anthemis aciphylla Boiss. var.aciphylla (Asteraceae) were investigated by agar-well diffusion assay. These extracts were tested in vitro against 26 bacterial and 3 yeast species. Etyhl acetate and acetone extracts of C. derderiifolia, S. aleurites and A. a.var. aciphylla showed antimicrobial activity in varying degrees on all the microorganisms tested. However, chloroform and ethanol extracts of all the plants were not active on some microorganisms tested. Ethyl asetate extracts of the samples exhibited stronger and broader spectrum of antimicrobial activity as compared to ethanol, aseton and chloroform extracts. Therefore, minimal inhibitory concentration (MIC) of only ethyl acetate extracts of the samples was determined for seven bacteria chosen from agar-well diffusion assay. MIC values of the extracts were between 250-125 ?g/ml. In conclusion, ethyl asetate extract of C. derderiifolia was the most active against Aeromonas hydrophila both in agar-well diffusion and MIC assay
