“…Considering the ideal anesthesia should meet characteristic of anesthesia time within 3 min and recovery time within 5 min, optimum anesthetic concentration of MS-222 (Sigma, USA) and lidocaine-HCl (Hong Sung Chemical, Korea) with 1,000 ppm NaHCO 3 determined 125 ppm (MS-222) and 800 ppm lidocaine-HCl /1,000 ppm NaHCO 3 , respectively depending on result of previous study (Tables 1 and 2) [4]. Anesthesia criterion was determined from the time when fish were stocked in anesthetized water to the time of stage A6 state, in which fish were perfectly sedate with minimum opercular movements [4,8].…”

“…Traditionally, chemicals such as urethane, ether and chloroform were used to anesthetize fish; however, these substances are now restricted because they all contain carcinogens [4]. Currently, tricaine methanesulfonate (MS-222) is widely used to anesthetize fish, including food fish, although it is considered mildly toxic as an edible anesthetic according to the US Food and Drug Administration (FDA), which requires that fish treated with MS-222 undergo an obligatory 21-days withdrawal period [2].…”

Blood (hematocrit, hemoglobin and red blood cell) and plasma (cortisol, glucose, lactic acid, Na + , Cl -, K + , osmolality, aspartate aminotransferase and alanine aminotransferase) factors in greenling, Hexagrammos otakii after MS-222 and lidocaine-HCl anaesthetic were determined. Greenling (mean body length: 25.8 ± 1.6 cm, mean body weight: 194.5 ± 33.8 g) were exposed to concentrations of 125 ppm MS-222 and 800 ppm lidocaine-HCl at 18°C. Blood was collected from ten fish after anesthesia 0.5, 1, 3, 6 and 24 hours, respectively. After anesthesia, the concentrations of hematocrit, hemoglobin, red blood cell, cortisol, glucose, lactic acid, osmolality, Na + , K + , Cl -, aspartate aminotransferase and alanine aminotransferase were determined. Control and experimental group displayed significant increases in plasma cortisol concentrations from their respective prestress levels at 0.5 hour after anaesthetic (P<0.05). Concentrations of glucose were increased from 22.3 ng/ mL to 28.5 ng/mL (0.5 hour), 31.0 ng/mL (1 hour) in experimental group, respectively. Lactic acid concentrations for experimental group were lower than those for control group at 0.5, 1 and 3 hours. In other items, control and experimental group did not show significant differences in this before and after anaesthetic. The results indicate that lidocaine-HCl and MS-222 can be used as suitable anaesthetic for the greenling.

“…Oxidative metabolism in higher vertebrates is controlled by thyroid hormone(s) but its endocrine regulation in poikilothermous animals (except in reptiles, see Maher, 1965; has not been established (Dodd & Matty, 1964). However, in goldfishes (Hasler & Meyer, 1942;Hoar, 1958) there are reports that gonadal steroids alone, and not thyroxine, stimu¬ late oxygen consumption. In reptiles which occupy an important position in the phylogeny of vertebrates, both thyroid hormone as well as male hormone influence respiration.…”

Orchidectomy in Hemidactylus flaviviridis led to significant reduction of thyroidal 131I uptake, thyroidal content of thyroxine, plasma protein-bound iodine and oxygen consumption of isolated liver and skeletal muscle (at 30 \ s=deg\ C). Administration of testosterone to orchidectomized lizards restored these parameters to normal levels. Dependence of thyroid function and oxidative metabolism on male hormone may be a general feature in reptiles. This hormone may, therefore, be of greater physiological importance in these animals than in other vertebrates. Since reptiles occupy a crucial phylogenetic position in the animal kingdom these findings are important from the point of view of evolution of the functional aspects of hormones in vertebrates.The results also show that thyroid function is inhibited by oestrogen(s) in this lizard. This may be an adaptive compensatory measure to control (through effects of the thyroid on metabolic activities) the extra expenditure of energy usually associated with such energy-consuming functions as ovulation and egg-laying.

“…The influence of this gland upon the metabolic rate of higher vertebrates is well established, but, despite the recent demonstration that the teleost thyroid contains a principle which raises the oxygen consumption of mammals (Smith & Brown, 1952), most attempts to influence the rate of oxygen consumption in fish themselves by the use of thyroid stimulants or depressants have been negative (Root & Etkin, 1937;Etkin, Root &Mofshin, 1940;Hasler &Meyer, 1942;Smith &Everett, 1943),the only positive result being that of Smith &Matthews (1947),who injected extracts of the Bermuda parrot fish into the Bermuda white grunt. .…”

SummarySurgical thyroidectomy has been successfully performed on the dogfish, Scyllium canicula, and has been shown to have no signficant effect on the animal's oxygen consumption over a period of 6 weeks.The injection of extracts of dogfish thyroid into adult male white rats results in an increase in the animal's oxygen consumption of the same order as that produced by mammalian thyroid preparations.The significance of these results is discussed in the light of recent investigations of thyroid function in fish.
