Effects of Different Growing Media on Plant Growth and Nutrient Contents of Petunia (Petunia Hybrida)
(Pamukkale University, 2020) Gülser, F.; Çığ, A.; Gökkaya, T.H.; Atmaca, H.
The objective of this study was to investigate the effects of different growing media on plant growth and nutrient contents of petunia (Petunia hybrida). The experiment was conducted in a chamber room under controlled conditions at the laboratory. Seven different media (soil, 3:1 soil: peat (P1), 2:1 soil: peat (P2), 3:1 soil: barnyard manure (BYM1), 2:1 soil: barnyard manure (BYM2), 3:1 soil: sugar beet pulp (SBP1), 2:1 soil: sugar beet pulp (SBP2)) were used as plant growing media. The experiment was ended after three months following transplanting of seedlings. Plant growth and flower parameters and macro-micro nutrient contents were determined in harvested plants. The highest stem diameter, branch number, flower diameter, flower stalk diameter, plant fresh weight and plant dry weight were in 2:1 ratio of soil: peat mixture as 7.00 mm, 6.33, 8.91 cm, 3.59 mm, 48.47 g and 4.52 g while the highest plant lenght, lateral branch number and flower number means were found as 27.43 cm, 24.67 and 24.67 in ratio of 3:1 soil: peat growing media respectively. The highest potassium, magnesium and zinc means of plants were obtained as 6.6%, 2.2% and 32.50 mg kg-1 in soil: barnyard manure (2:1) growing media while the highest phosphorus and calcium means of plants were found as 0.27% and 4.5% in soil and peat growing media respectively. The highest iron and copper means of plants were determined as 231 mg kg-1 and 32.50 mg kg-1 in ratios of 2:1 and 3:1 of soil: sugarbeet pulp growing media respectively. © IJSM 2019.
Hyperkalemia Occurring in a Patient With Psoriatic Arthritis Following Indomethacin Use
(2005) Sayarlioglu, H.; Atmaca, H.; Unalacak, M.; Dogan, E.; Erkoc, R.
Objective: To report a case of hyperkalemia possibly due to indomethacin use. Case Summary: A 52-year-old white woman with psoriatic arthritis for 16 years and diabetes mellitus for 3 years was admitted to the university hospital due to swelling and pain of wrists, elbows, knees and ankles for the last one month. The patient had been receiving methotrexate irregularly, but discontinued it 3 months ago. Physical examination and laboratory evaluations were compatible with diagnosis of exacerbation of psoriatic arthritis and type 2 diabetes mellitus. Two days after initiation of indomethacin and methotrexate, hyperkalemia developed with increase of blood urea nitrogen and decrease of creatinine clearance. Indomethacin was discontinued, and this resulted in normalization of laboratory findings between day 5 and 10 after discontinuation. Conclusion: The development of hyperkalemia caused by indomethacin is probably unusual, but it is important because indomethacin is a commonly used medication. This potentially serious complication can be prevented by careful attention to renal function and potassium balance in patients receiving indomethacin and other nonsteroidal anti-inflammatory drugs (NSAIDs), especially in patients with type 2 diabetes mellitus or preexisting renal disease.
