This study examined the overdose toxicity of Super-Neophensan, containing florfenicol and acetaminophen, upon pigs. SNP-3.0 (n=10) was administered at the dosage level of 3 kg/ton feed for 7 consecutive days, which is 3 times the recommended dose based on the guidelines of the manufacturer, and the control group (CON) (n=10) was administered the normal diet without the drug. The body weight, weight gain and feed efficiency in SNP-3.0 treated with the drug for 14 days post-administration showed no significant differences compared with those in CON. In hematological and blood biochemical analyses, all parameters were not affected by over-dosage of the drug. In the same way, there were no significant differences between SNP-3.0 and CON on markers for liver and kidney functions. As no adverse effects were observed with the drug in an overdose oral toxicity test, this study suggests that the drug was identified as a safe agent in pigs administered with three times the recommended dose.

Postoperative delirium is defined as an acute change with cognitive status characterized by fluctuating consciousness and unattention occuring within 30 days after operation, Postoperative delirium is a common complication of surgery in elderly people, but have been often unrecognized, under-diagnosed, under-treated, and under-investigated. We present a case of postoperative delirium in adult woman patient after spine surgery who did not have any problem in preoperative evaluation.

Nowadays, according to the tendency to the large size and the high speed of a ship, a main engine wants speeding up and raising power. On the contrary, various Diesel Engines adopted in recent days cause the increase of cylinder numbers and the complex mechanism of the system of an intake and exhaust valve and a high compressin ratio. Accordingly the principle and the structure are attended with lots of problems in simplification of a reciprocating piston engine and in increasing of rapid progressing R. P. M. At this point, we have to avoid the above difficult problems in an internal combustion engine in future and getting rid of a reciprocating motion mechanism to bring about vibration, I wall state on the historical consideration and the principle of a N. S. U -Wankel Rotary Engine which is excellent in getting power by rotating directly the rotor coresponding to a piston.

A study of the tissue depletion of florfenicol (FFC) administered orally to pigs at a dose of 0.05 kg/ton feed for 7 days was performed. Sixteen healthy cross swine were administered with FFC. Four treated animals were arbitrarily selected to be sacrificed 1, 3 and 5 days after the end of treatment. FFC residue concentrations in muscle, liver, kidney, and fat were determined using high-performance liquid chromatography (HPLC) with ultraviolet photometric detector at 230 nm. The correlation coefficient (R2) of the calibration curve for florfenicol amine (FFCa) was > 0.997 and the limits of detection and quantification were 0.012 and 0.040 μg/mL, respectively. Recovery rates in swine edible tissues ranged from 79.1 to 93.5%. In the FFC-treated group, FFC residues at 3 days post-treatment were below the maximum residue limits (MRLs) in muscle, kidney and fat, and those at 5 days post-administration were below the MRLs in all edible tissues. These results suggest that the withdrawal period of FFC after the drug treatment might be 5 days, which is a sufficient amount of time for reduction of the FFC residues below the MRLs in all edible tissues.
노인에게서 대퇴골 고관절 치환술시 마취관리 : 증례보고 A case report

An Ninety-year old female patient was transferred to the operating room for hip arthroplasty under regional anesthesia. Pulmonary (unction studies revealed severe restrictive pattern, and cardiomegaly noted in her chest X-ray examination. For the prevention of hypothermia, we first prepared blanketrol and IV line warmer and attempted epidural anesthesia, but we failed. We then did spinal anesthesia which was successfully administered. After performing regional anesthesia and injection of methylmethacrylate bone cement into the intramedullary canal, blood pressure and pulse was stable and no other evidence of instability. In the recovery room, she did not show any other symtoms, and three weeks later, she was discharged hospital without any sequelaes.

As the most suitable quality Bunker-A (JIS K-2205) has closely approximation for the main diesel engine (6MA-HTY) in the training, Og-San. But it is so expensive for daily use that we can find the poor economy. Here we cannot too strongly advise the necessity of any substitution. The author has got how to make use of the Light Residual Fuel Oil which is lower both in quality and price than Bunker-A mentioned above. For the useful management, two heater tanks and one oil purifier which are the minimum increase are fitted to the existing facilities in the engine room of Og-San.
