Pesquizas sobre a acção physiologica das toxinas bacterianas: II - sobre os efeitos dos filtrados de culturas antigas de bacillo coli administrados por via digestiva a coelhos

This paper deals with experiments of propination of small doses of filtrates of old cultures of colon bacilli to normal rabbits by stomach tube. The experiments have demonstrate that the propination of the filtrates produces a decrease of weight in the animals in experience. The loss of weight just after the first propination of the filtrate to the rabbit and continues progressively leading to emaciation and death if new doses are given. If the propination was too much prolonged the animals goes to death, notwithstanding the propination of the filtrates being discontinued.

Ensaios terapêuticos com penicilina: II - Sífilis: (Nota prévia)

Seis sifiliticos foram tratados com penicilina em doses baixas, no Hospital Evandro Chagas, do Instituto Oswaldo Cruz. Protossifilomas foram bacterioscópicamente negativos entre 3 e 6 dias e cicatrizaram completamente entre 10 e 13 idas, com a aplicação de 1.200 a 2.400 unidades Oxford por 24 horas. Condilomas sifiliticos e placas mucosas hipertróficos tiveram bacterioscopia negativa entre 6 e 8 dias, cicatrizaram completamente entre 10 e 20 dias, com a aplicação de 1.200 unidades por 24 horas. Porém, doses de 4.800 unidades, no mesmo espaço de tempo, forma insuficientes para controlar outras manifestações luéticas secundárias (roséolas, placas mucosas). Em 3 casos sob contrõle sorológico, verificou-se que a negatividade das reações não acompanha imediatamente a cura clínica. Além disso, conforme já foi observado também com a bouba, os resultados dos testes sorológicos oscilam mezes a fio, negativando e voltando à positividade.

Estudo sôbre flebotomus no vale Amazônico: parte II. descrição de F. Dunhami, F. Melloi e F. Wagleyi (Diptera, Psychodidae)

Três espécies novas de Flebotomus da Região Amazônica são descritas sob os nomes de F. dunhami, F. melloi e F. wagleyi. Tôdas apresentam quatro espinhos no segmento distal da gonapófise superior e gonapófise mediana não bifurcada mas provida de um apêndice na face superior que dá ao conjunto a aparência de uma bifurcação.

Estudos sobre a dosagem microbiologica das vitaminas do complexo B - II. Niacina

The microbiological assay method of Snell and Wright for niacine was studied and some modifications of the basal medium were proposed. A maximal growth of the "Lactobacillus arabinosus" was obtained by the addition to the basal medium of 25 mg % asparagine and increasing the percentages of glucose and sodium acetate. Liver and yeast extracts were assayed satisfactory and the niacine added was recovered quantitatively.

Notas sôbre Tabânidas brasileiros: II. Fidena callipyga n. sp.

Fidena callipyga n. sp. is described from three specimens, in the collections of the INSTITUTO OSWALDO CRUZ. It is related to Fidena ornata kröb., 1931 and Fidena aureopygia Kröb., 1931. It can be distinguished from both by the postfrons which is comparatively broader in relation to the high, by the light golden-yellow color of the beard, in striking contrast to the hairs on the propleurae and anterior coxae, and by the extent of the golden-yellow on the abdomen. In size, ornamentation and principally in the form of the palpi it is nearer to aureopygia. Fidena callipyga n. sp. and Melpia miniatistola (End.), 1925 constitute a pair of convergent forms, they differ however not only as to hairs on the mesonotum, femora and hind tibiae and form of the abdomen, but also as to the color of the beard.

Ensaios terapêuticos com penicilina V-Bouba (Framboesia, pian, yaws): I - Dose curatina mínima: II - Redução do número de injeções diarias: III - Redução de tempo de tratamento pelo emprêgo de doses mais elevadas

This report belongs to the series of works carried out Oswaldo Cruz Ins¬titute, on the treatment of treponematosis with penicillin. The present report deals with investigations performed in order to ascer¬tain the following points: 1) the mininal curative dosis for the initial lesions of yaws; 2) the effect of reduction of the number of injections each day, to verifie the possibility of application of penicillin in the prophylaxis of yaws in rural zones; 3) reduction of the time of treatment by application of high dosis. 1) With dosis of 150 and 100 Oxford units each four hours, clinical reco¬very was obtained after 17 days of treatment. With 50 O.u. during 40 days clinical recovery was not obtained. 2) a) With 3 injections of 400 O.u. each day (6,12 and 18 hoórs clocks) clinical recovery was obtained after 14 to 16 days; b) with 2 injections of 400 O.u. each day (6 and 18 hoors clocks), clinical recovery was obtained after 16 to 23 days; c) with 1 injection of 1.600 and 3.200 each day, clinical recovery was obtained after 30 and 20 days. 3) With dosis of 33.3 and 46.7 O.u. by each kilo of weight each four hours, during 15 days, clinical recovery was obtained more or less in 25 days. The same result was obtained with the dosis of 61.5 and 166.7 O.u. by each kilo of weight, each four hours, during 4 days. But with 100.000 O.u. in fine dosis of 20.000 in a day ou by, clinical recovery was not obtained.

A vegetação do município de ilhéus, Estado da Bahia: II observação e ligeiras considerações acêrca de espécies que ocorrem na regiçao: chave analítica das espécies arbóreas

I - Short description of the species. II - Analytic key of the trees. III - List of the species collected with register number and author's number. SHORT DESCRIPTION OF SPECIES - This section includes a short morphological analysis of the species and the study of their geographic distribution, locality, habitat and regional zonation. ANALYTIC KEY OF THE TREES - The author was obliged to make a morphological key for his use on account of the great difficulty met in identifying the species in the field. LIST OF SPECIES COLLECTED WITH REGISTER AND COLLECTOR'S NUMBERS - As the majority of the species from Ilheus are paratypes of the types described in "Flora Brasiliensis" it was decided to publish this list. The author's chief objective was to call the attention of specialists tothe undetermined material with a view to interesting them in studying it.
