Observações sôbre a anestesia geral pelo hidrato de cloral na prática da cirurgia veterinária

In this paper the A. A. report the observations about the general anesthesia by chloral hydrate on the veterinary surgery. The observations were made on emasculation practices of horses, mules and hogs. It was possible to establish the following conclusions: 1) The choral hydrate presents low cost, it harmless, and is of easy application. 2) The more recommendable dosis for equine and swine were : 12-13 g per 100 k of body weight, in destilled water solution at 30 and 20%, respectively. 3) The anaethestic was injected by intravenous way with good results; in horses and mules the applications were made in the jugular; in swine, in the anterior vena cava, as was described by Carle and Dewhirst, because it was impracticable in the ear vein. 4) The dosis applied produced deep narcosis not lasting to long and with no danger to the animal's life. 5) In the case of fattening hogs, it must be made a discount of about 40% on the body weight, to calculate dosis to be employed. 6) The tables A and B show the results, that may be considered as good.

Ciclo de vida pós-marsupial e crescimento de Metamysidopsis elongata atlantica (Crustacea, Mysidacea, Mysidae) em cultivo de laboratório

Metamysidopsis elongata atlantica (Bacescu, 1968) was reared in the laboratory for 45 days at 20±1°C and salinity of 30ppt. Growth curves (von Bertalanffy model) were calculated for both sexes and for each sex. The daily rate of carapace growth was significantly different between females and males (F test, p <0.05). Before the sexual maturity (14 days), the growth rate of females was higher than that of males (females, 0.0457 mm day-1; males, 0.0448 mm day-1). After the maturity (15 to 45 days), these rates decreased similarly for both sexes (females, 0.0203 mm day-1; males, 0.0174mm day-1). The average growth rate was 0.0207mm day-1 over the 45 days. Twelve molts were observed in a period of 60 days. The first five molts occurred up to 14 days old (age of the sexual differentiation), with a mean intermolt period of 2.9 days. From the 6th molt it increased to 5.6 days. The results suggest that the use of the carapace length is a good measure to calculate the growth and longevity of the organisms.

Seasonal variation of the effect of high-carbohydrate and high-protein diets on the intermediate metabolism of Parastacus brasiliensis (Crustacea, Decapoda, Parastacidae) maintained in the laboratory

The goal of this study was to evaluate the effect of a high-carbohydrate diet (HC) and a high-protein diet (HP) on the metabolism of the crayfish Parastacus brasiliensis (Von Martens, 1869), collected in different seasons and maintained in the laboratory for 15 days. Crayfish were collected monthly from January 2002 to January 2004 at São Francisco de Paula, Southern Brazil, in Guarapirá stream. In the laboratory, the animals were kept submerged in aquariums under controlled conditions. They were fed ad libitum, for 15 days with either a HC or HP diet. At the end of this period, haemolymph samples were collected, as were hepatopancreas, gills, and abdominal muscle that were removed for determination of glycogen, free glucose, lipids, and triglycerides. The haemolymph samples were used for determination of glucose, proteins, lipids, and triglycerides. Statistical analysis (ANOVA) revealed significant seasonal differences in biochemical composition in crayfish maintained on HC or HP diets. Independent of the diets offered to the animals and the controlled conditions for 15 days, the indications of seasonality were unchanged. The observed changes seemed to be related to the reproductive period. Moreover, the HC diet increased all energy reserves in adult parastacids, which may aid in reproduction.
