RESUMO
The present paper reports the occurrence of perineal hernia in 10 dogs, establishing the presence of the urinary bladder and the prostate as components of the hernial content. The dogs were of different breeds, their ages varying from 7 to 14 years. Five of the animals presented the process on the right side, four on the left and in only one the process was bilateral. In the surgical reparation of the perineal hernia, as an important step to prevent reincidence of the process, the author performed the prostatectomy according to the technique recommended by Matera (1952), allowing satisfactory functional results. The structures involved in the process were identified and utilized with the objective or complete recuperation of the anatomical region, a procedure that revealed itself as highly effective. Until the present moment, reincidence of the process or other complications consequent to the technique employed were not verified in the cases here reported.

RESUMO
The author present the result of the qualitative chemical composition of the urinary calculy in the canine species. The observations are referring to 85 urinary calculy obtained from animals attended at the ambulatory of the surgical clinic of the Faculty of Veterinary Medicine of São Paulos University. Those animals were of different sexes, races, sizes and of age varying between 2 and 16 years. After verifying the lack of studies referring to the chemical composition of urinary calculy of dogs in Brazil, the author present bibliographical review about this matter as well as the technical analysis used. He compares the results obtained with those from foreign authors and comes to the following clues: 1 The calculy compound of phosphates are the most commons. The percentage is 65,8% of magnesium ammonium phosphate (triple phosphate), and 35,2% of calcium and magnesium phosphate (amorphus phosphate). 2 Follow in frequence the calculy compound of oxalates in the proportion of 45,8%, greater as the mentioned by other authors. 3 The presence of cholesterol in the analysis of urinary calculy of the dogs, 29,5%, is very different from the observation made by other authors which, except one, do not mentioned it. 4 The fibrine, element not mentioned by the authors was observed in 34,1% of the calculy. 5 Cystine, uric acid and urates are observed by authors relatively often,

RESUMO
In this paper the authors studied the influence of ether anesthesia on both memory and brain acetylcholine content. The results suggest that the anesthetic agent prevents the conditioned avoidance response if administered up to 5 minutes after training. The brain acetylcholine content appeared to be inversely parallel to the time elapsed between anesthetic state and sacrifice of the animals. Results suggest that probably exist a relationship between memory and brain acetylcholine content.

RESUMO
The authors emphasize the importance of knowing the normal values of pseudocholinesterase in serum of buffaloes of the Murrahs race. They point out the necessity of enlarging the knowledge related with the normal biology of this animal species, that has gained prominence in our environment. The authors used 30 animals, adults, female, pure by origin or by cross-breeding, maintained under clinical observation in the inland of São Paulos state. The electrometric method of MICHEL was utilized to determinate the activity of cholinesterase in serum. The results were statistically analyzed, employing a paired t test. The mean value of activity that was found for these animals was pH 0,1232, table I. They verify that the bubalis do not integrate the animal classification suggested by CHARY et al. (1). Finally, they concluded that the bubalis of Murrahs race present pseudocholinesterase activity in serum very similar to the bovines.
Os autores ressaltam a importância do conhecimento de valores séricos normais de pseudocolinesterase em búfalos da raça Murrah. Destacam a necessidade de ampliar os conhecimentos relacionados com a biologia normal dessa espécie animal, cuja exploração zootécnica vem ganhando destaque em nosso meio. Utilizam 30 animais adultos, sexo feminino, puros de origem ou puros por cruza, mantidos sob vigilância clínica, no interior do Estado de São Paulo. Empregam o método eletrométrico de Michel para as determinações da atividade sérica da pseudocolinesterase. Os resultados são submetidos a análise estatística através deum teste t pareado. Encontram como valor médio de atividade para estes animais o valor de delta pH 0,1232 (Tabela I). Constatam que os bubalinos não integram a classificação proposta por Chary e colaboradores (1). Concluem finalmente que os bubalinos de raça Murrah apresentam atividade sérica de pseudocolinesterase bem próxima aos bovinos.
RESUMO
Pseudocholinesterase activity was performed in 97 pure line and cross breed cows of the Red and White Holstein, Black and White Holstein and Jersey breeds, with ages ranging from 2 to 14 years. The electrometric determination of serum pseudocholinesterase was processed following the MICHEL technic (1949). A slight difference in pseudocholinesterase activity was found between the Holstein breeds and a more intense difference between these and the Jersey breed. Animals from 2 to 7 years of age showed higher delta pH/h average values than animals of the older group (8 to 14 years). The advance in age is marked by functional alterations, which are able to contrast more easily with the normal physiological behavior of younger organisms. Such fact allowed the admission of a metabolic interference, predominantly anabolic between the young animals and predominantly catabolic between the older ones. The final average were statistically analyzed by a Hierarchical Analysis of Variance.
Foi realizado o dosamento da atividade da pseudocolinesterase em 97 vacas puras de origem ou puras por cruza, das raças Holstein vermelha e branca, Holstein preta e branca e Jersey, com idades variando de 2 a 14 anos. A determinação eletrométrica da pseudocolinesterase sérica foi praticada segundo técnica descrita por MICHEL (1949). Observou-se discreta diferença da atividade pseudocolinesterásica entre as raças Holstein e diferença mais evidente para a raça Jersey. Os animais de 2 a 7 anos de idade apresentaram valores médios de delta pH/h mais altos do que os animais de 8 a 14 anos. A idade mais avançada é marcada por alterações funcionais, capazes de contrastar com o comportamento fisiológico normal do organismo jovem. Este fato permitiu-nos admitir a hipótese da interferência metabólica, predominantemente anabólica entre animais mais jovens e, predominantemente catabólica entre os mais idosos. Os resultados alcançados foram submetidos a cálculo estatístico, através de Análise de Variância Hierárquica.
RESUMO
The authors poisoned experimentally 15 rabbits by an intravenous administration of an aqueous extract of Holocalix balansae, Mich. The animals were distributed in 3 groups, each one composed by 5 animals. Group A was considered as control, and did not receive any protection by hidroxocobalamin. Group B received 10 mg/Kg of hidroxocobalamin intravenously, 5 minutes after as intravenous injection of an aqueous extract of Holocalix balansae, Mich. (3,0 g/K). Finally, group C received an intravenous dose of hidroxocobalamin (10 mg/Kg) 5 minutes before the intravenous administration of the aqueous extract of Holocalix balansae, Mich. (3,0 g/Kg). The vegetal extract was prepared accordingly with the procedure of SOUZA (1967). The presence of cyanide was confirmed by the qualitative determination of FEIGL (1954). All animals of group A died 10 minutes after the injection of the aqueous extract preceded by marked respiratory alterations. No death was observed among the animals of groups B and C. Alterations of the respiratory frequency were observed in the animals of group B, during the 5 minutes before the administration of hidroxocobalamin. No alterations were observed in the animals of group C. Finally, the authors concluded that the hidroxocobalamin is an ideal substance for the prophylaxis and treatment of cyanidric poisoning by Holocalix balansae, Mich, or any other cyanogenetic
Os autores provocaram a intoxicação experimental em 15 coelhos pelo extrato aquoso do Holocalix balansae, Mich., através da administração endovenosa (veia marginal da orelha). Os animais foram distribuídos em 3 grupos, constituídos por 5 animais cada um. O grupo A considerado testemunho, não recebeu nenhuma proteção de hidroxicobalamina. O grupo B, recebeu 10 mg/Kg de hidroxocobalamina endovenosa, 5 minutos após a injeção endovenosa do extrato aquoso de Holocalix balansae, Mich. (3,0 g/Kg). Finalmente, o grupo C recebeu previamente hidroxocobalamina (10mg/Kg) endovenosa, 5 minutos antes da administração endovenosa de Holocalix balansae, Mich. (3.0 g/Kg). O extrato aquoso de Holocalix balansae, Mich. foi preparado de conformidade com a orientação imprimida por SOUZA (1967). A presença de cianeto nas amostras foi confirmada através da determinação qualitativa de FEIGL (1954). Constataram morte de todos os animais do grupo A, 10 minutos após a injeção do extrato aquoso de Holocalix balansae, Mich., precedida por acentuadas alterações da frequência respiratória. Não foi constatada nenhuma morte entre os animais pertencentes aos grupos B e C. Alterações da frequência respiratória foram observadas entre os animais do grupo B, nos 5 minutos que precederam às injeções endovenosas de hidroxocobalamina e após as injeções de extrato aquoso de Holocalix balansae, Mich. Os animais do grupo
