NarayanSpecies of Pleurotus possess various medicinal properties including hypoglycemic and hypocholesterolemic activities. The feeding effect of the mushroom Pleurotus florida in powdered form was evaluated on growth, blood glucose and cholesterol level in alloxan-induced diabetic albino rats against control. The starch was estimated in dry mushroom and found to be 0.28% (dry weight). The result indicated no significant difference in respect of gaining body weights between Bengal gram-fed and mushroom-fed groups. For studying antidiabetic effect, the control group and half of alloxan-induced (100 mg/kg i.p) experimental groups were fed on normal diet with Bengal gram whereas the other half of alloxan-induced group was fed on same diet but with additional mushroom powder. Blood samples were analysed for glucose, serum cholesterol, triglycerides and uric acid levels on 7th, 14th, 21st and 28th days of alloxan treatment. Body weights and mortality were noted during the period of study. The diabetic group administered with mushroom diet showed significantly decreased level of blood glucose and cholesterol compared to the counterpart. Estimation of lipid profile revealed much lower LDL cholesterol in mushroom fed diabetic group than in non- mushroom fed diabetic control group. The study, thus, points out the prominent effect of feeding dried mushroom (P. florida) on growth of albino rat and positive effect of P. florida on lowering blood glucose and cholesterol level in diabetic rats thereby suggesting its hypoglycemic and hypocholesterolemic effect.Öğe Kırıkkale ili makrofungus florasının tespiti ve genetik karakterizasyonu(2014) Güler, Perihan; Çelebi, Ayten Keskin; Türkoğlu, Aziz[Abstract Not Available]Öğe Macrofungi flora of Beytepe campus area (Ankara)(2003) Güler, Perihan; Mutlu, BirolIn this study, the fungi were collected from Beytepe Campus area in the years of 1999 and 2000, particularly autumn and spring.

G.The present study presents the development of mycelium of Morchella conica where different concentration of sucrose added at different agar media. For this sucrose have been added as 0.25, 0,50, 0.75, 1.00 and 1.25% concentration to wheat agar, potato dextrose agar, malt extract agar and complete medium yeast agar The radial growth speed, morphologic specifications, radial growth radius and pigmentation of mycelium were taken as criteria, the development period of mycelium in wheat agar was completed in 4 days and mycelium were very thin. The colonization period of the mycelium was determined; 7 days in potato dextrose agar, 5 days in malt extract agar and 5 days at complete medium yeast agar The development of the mycelium; at potato dextrose agar was dense and circular at malt extract agar and at completed medium yeast agar was rhizomorphic. Mycelium has developed very well at sucrose medium and formed creamy and light yellow pigmentation.Öğe Propolis effect on sclerotial formations of Morchella conica Pers.(Pakistan Botanical Soc, 2005) Güler, Perihan; Bozcuk, Suna; Mutlu, Fatma; Sorkun, KadriyeIn this study, the effects of propolis at different concentrations on sclerotial formations of Morchella conica Pers., were examined. The propolis used was obtained from three different regions of Turkey. The propolis extracts were prepared at 0.5, 1.0, 1.5 and 2.0 EEP concentrations and they were added to malt extract agar. During the incubation period of 10 days, the mycelium of control group developed rhizomorphic and parallel oil the surface of agar medium and there was no pigmentation. On the other hand, the mycelium did not develop normally oil the agar medium in the presence of propolis but the sclerotial formations were observed. The sclerotial cells were spherical in form, with thick walls and they were characterised with different pigmentations.Öğe Protective effect of kombucha mushroom (KM) tea on chromosomal aberrations induced by gamma radiation in human peripheral lymphocytes in-vitro(Triveni Enterprises, 2010) Çavuşoğlu, Kültigin; Güler, PerihanThe aim of this study was to investigate the potential radioprotective effect of kombucha musroom tea (KM-tea) on gamma radiation (gamma)-induced chromosomal aberrations (CAs) in human peripheral blood lymphocytes in vitro. For this purpose, we used in vitro dose-effect relationship, and correlated these data with statistical parameters. CAs were classified into six major types as break, dicentric, acentric, fragment, gap and ring. Mitotic index (MI) and the numbers of aberrant metaphases (AMN) were also calculated for each donor Six groups of the lymphocytes were prepared by in vitro culture according to the standard protocol. Group I (control) did not receive any gamma-radiation or KM-tea, Group II (positive control) was treated with 1000 mu l dose of KM-tea alone, Group III was treated with 5 Gy dose of gamma-radiation alone, Group IV was treated with 250 mu l dose of KM-tea before irradiation, Group V was treated with 500 mu l KM-tea before irradiation, Group VI was treated with 1000 mu l KM-tea before irradiation. The results indicated that all KM-tea supplemented lymphocytes had lower frequency of CAs than in the group treated with gamma-radiation alone (p<0.05). It was seen that KM-tea had a protective effect againist CAs particularly at 500 and 1000 mu l doses. Besides, MI values increased and AMN decreased after application of KM-tea in a dose/dependent manner In vitro results showed that KM-tea supplementation may decrease the frequency of CAs and its radioprotective action against ionizing radiation is dose-dependent.Öğe Rhizopogon roseolus (Corda) Th.
