The influence of Mg treatment on the growth and mineral elements of tall fescue (Festuca arundinacea Schreb.) 'Justice’, perennial ryegrass (Lolium perenne L.), 'Paragon', creeping bentgrass (Agrostis palustris Huds), 'Penn-A1' and Kentucky bluegrass (Poa pratensis L.) 'Nassou' were investigated in the greenhouse from the 2nd of October to the 4th of December in 2006. The minimum temperature was 13.5±1.4℃ and the maximum one was 30.7±1.6℃ during the period of the experiment. The Mg treatment ranged from 0 me/L to 8me/L in solution. Tall fescue 'Justic' showed the longest shoot length at Mg 2me/L, and had the highest number of tillers at Mg 1me/L and 2me/L, but there was no difference between treatments, It showed the best fresh weight and dry weight of the shoot at Mg 2me/L, but there was no difference between treatments. It showed the longest root length at Mg 1me/L, and had the best fresh weight and dry weight of the root at Mg 4me/L, and there was difference between treatment. Perennial ryegrass 'Paragon' showed the longest shoot length and had the highest number of tiller at Mg 2me/L. It showed the best fresh weight and dry weight of the shoot at Mg 4me/L, and there was difference between treatments. It showed the longest root length at 2me/L and had the best fresh weight and dry weight of the root at Mg 4me/L and the was difference between treatment. Kentucky bluegrass 'Nassou' showed the longest shoot length at Mg 4me/L, but there was no difference between treatments. It showed the highest number of tiller at Mg 2me/L, and had the best fresh weight and dry weight of the shoot at Mg 4me/L, and there was difference between treatment. It showed the longest root length at Mg 4me/L, and had the best fresh weight and dry weight of the root at Mg 2me/L, and the root length was difference between treatment. In the case of creeping bentgrass 'Penn-A1', it showed the longest shoot length at Mg 4me/L, and had the highest number of tillers at Mg 2me/L, It showed the best fresh weight and dry weight of the shoot and the root at Mg 4me/L, and there was differece between treatments. Aa application rate of Mg concentration higher, the content of mineral Mg within shoot increased, while the content of Ca within shoot decreased, and there was difference between treatments. The concentration of Mg treatment had no effect on the content of mineral N, P, K, Fe, Mn within shoot.

We report a very rare case of unilateral blepharoptosis and swelling as an unusual complication of a filler injection. The patient received a filler injection into the forehead 4 years previously by an unlicensed practitioner. In the operation, an encapsulated yellowish cyst with inflammation was found to be adhered to the orbital septum and was excised. To prevent additional inferior migration of the remaining foreign body in the forehead, the retro-orbicularis fascia and preaponeurotic fat pad area were sutured, with the exception of the levator aponeurosis. This cyst-like mass was histopathologically proven to be a multiple pseudocyst. After excision, the swelling disappeared and the ptotic eyelid also improved. The galea is connected with the posterior orbicularis fascia. The galea and posterior orbicularis fascia layer can function as a pathway through which the injected material can migrate from the forehead to the upper eyelid. Weakening of the orbicularis retaining ligament and leakage of the foreign body through the supraorbital foramen may also cause filler migration. This case underscores the need for clinicians to be aware of the potential migration of filler even many years after an injection. We advise that filler injections should be performed by trained physicians and that it should be made known that migration is possible.
