A mixture of local anesthetic and epinephrine provides hemostasis for ear microsurgery. However, epinephrine has adverse cardiovascular effects, such as arrhythmia, pulmonary edema, and even cardiac arrest. We have experienced catecholamine-induced cardiovascular crisis, with severe hypertension, tachycardia, and acute pulmonary edema, after subcutaneous infiltration with a 2% lidocaine and 1:200,000 epinephrine solution. The patient recovered without any apparent sequelae after intensive care, including diuretics, steroids, and nitroglycerin for the hypertension and pulmonary edema, and a vasopressor for the subsequent hypotension.

Experiments were performed to find out the physico-chemical properties of milt and the sperm motilities in various conditions using the grey mullet, Mugil cephalus. The average concenhation of sperm in the milt was 1.11±0.36×10^(10)/㎖. Spermatocrit was 96.7±2.6. pH and osmalality of seminal fluid were 7.8±0.1, 370±6 mOsm/㎏, respectively. Total protein concentration of sperm was higher than that of seminal fluid, but total lipid concentration of seminal fluid was higher than that of sperm. The sperm motility was high in the diluent of milt : artificial seawater (1:10, by volume) and in 822 mOsm/㎏ and 983 mOsm/㎏ similar to seawater osmolality, but it decreased after 20 minutes. But activity of sperm was highly maintained in 482 mOsm/㎏ which was a little higher than osmolality of seminal fluid, and was high in pH 7∼9.

장영진(Young Jin Chang),임한규(Han Kyu Lim),장윤정(Yun Jeong Chang),김형선(Hyung Sun Kim),허형택(Hyung Tack Huh) 한국수산과학회 1999 한국수산과학회지 Vol.32 No.3
To obtain the basic data for the preservation of liver puffer (Takifugu obscurus) sperm, experiments were carried out on the physicochemical proberties and cold storage of milt. The average number of sperm and spermatocrit in milt stripped were 1.13 ± 0.34 × 10^(10)/㎖ and 64.8 ± 1.4, respectively. Osmolality of seminal fluid was 266±2m0sm/㎏. Total protein and total lipid from sperm were higher than that from seminal fluid Ca^(2+) and Na^+ concentration were higher in the seminal fluid than in the sperm, while Mg^(2+) and K^+ concentrations were lower in the seminal fluid. When sperm o river puffer were preserved in 0 ± 0.5℃ with various diluents for 16 days, fertilization rate was 0∼0.7%. It suggested that cold storage of river puffer sperm was detrimental to sperm fertility.
사육수의 급격한 염분변화에 따른 숭어 ( Mugil cephalus ) 와 틸라피아 ( Oreochromis niloticus ) 의 생리적 반응
장영진(Young Jin Chang),허준욱(Jun Wook Hur) 한국수산과학회 1999 한국수산과학회지 Vol.32 No.3
Physiological responses (cortisol, glucose, GPT, GOT, total protein, hematocrit, sodium, chloride, potassium, total calcium and osmolality), growth and survival rates of grey mullet (Magil cephalus) and Nile tilapia (Oreochromis niloticas) by the manipulation of salinity were studied. Salinity was increased directly from freshwater to 33‰ and remained for 15 days. Then, salinity was decreased directly from seawater to freshwater and remained for other 15 days. All tilapias were dead at the third day, but 96.5% of grey mullet were survived at the 30th day. The grey mullet showed no significant differences for cortisol and glucose concentrations in the seawater and freshwater. However, those of the Nile tilapia were increased in seawater. The grey mullet showed no significant differences for sodium, chloride and potassium concentrations during experimental period. However, those of the Nile tilapia were significantly increased when exposed to seawater. The osmolality of grey mullet ranged between 293.5 mOsm/㎏ and 335.0 mOsm/㎏ for the whole experimental period.

장영진(Young Jin Chang),이복규(Bok Kyu Lee),강덕영(Duk Young Kang),박명룡(Myong Ryong Park) 한국수산과학회 1999 한국수산과학회지 Vol.32 No.5
Physiological responses of cultured olive flounder (Paralichthys olivaceus) on lowering seawater temperature sharply and continuously were studied with 4 experiments of temperature changes (Exp.I∼IV). In Exp.I, the temperature was decreased from 18℃ to 9℃ by the rate of 1℃/hr, threafter back to the initial temperature after 5 day. With the same conditions of temperature rate and 5 days interval, the temperature changes for Exp.II, III and IV were 20℃ to 17℃, 23℃ to 14℃ and 23℃ to 17℃, respectively. Serum cortisol and glucose were measured during whole experiments. Hematocrit (Ht), hemoglobin (Hb), red blood cell (RBC) and mean corpuscular hemoglobin concentration (MCHC) were measured in the Exp.I, and osmolality, electrolytes (Na^+, Cl^-, K^+, Ca^(2+)), total protein, aspartate aminotransferase (AST) and alanine aminotransferase (ALT) of serum, in Exp.II∼IV. Serum cortisol levels were significantly increased by the lowering temperature sharply during whole experiments, while serum glucose levels were increased only in Exp.III and IV. Ht, RBC and Hb were decreased as the water temperature was lowered, but MCHC was increased. The serum osmolality was reduced and the unstable changes of electrolytes were shown by the changes of seawater temperature. No significant changes in total protein, ALT and AST activity were observed.
해수사육에서 담수사육으로, 담수사육에서 해수사육으로 전환된 감성돔 치어, Acanthopagrus Schlegeli 의 혈액생리학적 비교

해산어류의 담수순화 양식을 위한 기초자료를 얻고자, 감성돔을 즉시 해수에서 담수로 (sFW구), 담수에서 해수로 (fSW구) 전환하였을 때의 혈액 생리학적 변화를 비교하였다. Cortisol의 농도는 sFW구에서 실험개시시에 34.2± 28.6ng/mL였던 것이 3시간째에 365.6±136.0ng/mL로 급격하게 증가하였다가 24시간째에 실험개시시 수준으로 회복되었다. fSW구에서는 실험기간동안 유의한 차이를 보이지 않았다. 글루코스 농도는 두 실험구에서 실험기간동안 유의한 차이는 없었다. 혈장 Na+, Cl-은 sFW에서 실험개시시에 각각 165.3±2.5mEq/L, 146.0±2.2mEq/L였던 것이 3시간째에 118.3±12.3mEq/L, 78.0±7.0mEq/L로 감소하였다가 30일째에 실험개시시 수준으로 회복하였다. 총단백질량과 AST는 두 실험구에서 실험기간 동안 유의한 차이가 없었다. ALT는 sFW구에서는 3시간째, fSW구에서는 24시간째부터 증가하기 시작하여 30일째에는 모두 실험개시시 수준으로 회복되었다. Ht는 sFW구에서 실험개시시에 18.5±0.6%로부터 12시간째 25.3±4.0%로 증가하였고, 24시간 이내에 실험개시시 수준으로 회복되었다. fSW구에서는 Ht, RBC, Hb가 12시간째부터 증가하여, 24시간 이내에 모두 실험개시시 수준으로 회복되었다. 생존율은 sFW구에서 5일째 25%로 급격히 낮아진 다음50일째에 0%를 나타냈으며, fSW구에서는 실험종료시에 85%의 높은 생존율을 보였다. Comparison of blood properties in juvenile black seabream (Acanthopagrus schlegeli) between transfer from seawater to freshwater (sFW) and transfer from freshwater to seawater (fSW) were investigated for 60 days. Plasma cortisol levels in sFW were significantly increased from 34.2 ±28.6 ng/mL at the beginning to 365.6 ±136.0ng/mL at 3 hours, and decreased to the beginning level at 24 hours. However, in fSW, no significant differences in the cortisol levels were recognized throughout experimental period. No significant difference was found in the glucose levels between sFW and fSW. The transfer from seawater to freshwater of juvenile black seabream resulted in reduced Na+ and Cl- concentrations for 24 hours (decreasing from 165.3±2.5, 146.0±2.2 to 118.3 ±12.3, 78.0 ±7.0 mEq/L, respectively), but these were completely recovered the beginning levels at 30 days. Total protein and AST showed no significant differences between the two rearing conditions, while ALT was markedly elevated at 3 hours in sFW and at 24 hours in fSW. Ht in sFW was increased from 18.5 ±0.6% at the beginning to 25.3 ±4.0% at 12hours, and was decreased to the beginning level at 24 hours. Ht, RBC and Hb in fSW were also significantly higher at 12 hours, but recovered to their initial levels at 24 hours. All fish were dead until 50 days in sFW while survival rate in fSW was 85% at the end of experiment.
