Em 20 portadores de Lepra, internados na Colônia de São Roque, Paraná, 13 dos quais eram da forma lepromatosa e os 7 restantes da forma nervosa pura ou tuberculoide, o autor estudou a reação intradérmica de antigenos bacilares (Leprolinas Souza-Araujo 1, 1a, 3, 5, 5a), comparativamente com as reações produzidas, ao mesmo tempo, com antÃgeno lepromatoso (Emulsão de lepromas, lepromina). Observou o seguinte: 1.° - Que a lepromina, comportou-se como habitualmente, isto é, negativa nos lepromatosos e ositiva nos nervosos e tuberculoides e sempre mais intensa ao fim da quarta semana. 2.° - Que as leprolinas provocam reações, que o autor não conclui serem positivas ou negativas no sentido imunológico da expressão em virtude de estar estudando-as neste sentido, nos leprotomatosos e tuberculoides, mas, sempre mais intensas entre a 1.ª e 2.ª semanas, diminuindo de intensidade na 3.ª e desaparecendo ou quase desaparecendo ao fim da quarta semana: nódulos, nódulos-eritema, ulcerações. 3.° - Que nestas reações houve destruição de tecidos, pois a presença tardia de cicatrizes, mesmo quando não houve ulceração, mostra êste fato. 4.° - Que as inoculações das lepromina, não trouxeram nenhum inconveniente a saúde dos paciente; embora um deles tenha apresentado nos primeiros dias leve reação geral; outro, intensa fusão de suas lesões nodulars de lepra e, dois outros, a chamada Reação leprótica.

The A. remembers the history of his lepra-culture and the method he uses to prepare with it the antigen called Leprolin Souza-Araujo, giving photographic illustrations upon the subject. The A. says that the results published about the general action of his Leprolin in leprosy must be revised or rectificated. But he says that the rapid action of his antigen upon perforant ulcers in lepers is consecrated by a large experience. He cured, in relatively short time, perforant ulcers in five lepers. Dr. CASSIANO, from Baurú leper Colony (S. Paulo) treated 21 such cases. The median time of treatment was 23 days and the median dosage of Leprolin injected in each patient was 7.7 cm3. All lesions were cured. After 18 months observation three cases relapsed and 18 (or 85.7%) remained cured. Dr. CALDEIRA, Director of padre DAMIEN Leper Colony (Ubá, Minas Gerais) treated regularly with Leprolin 50 cases of severe perforant ulcers and obtained cure in 46 (or 92%). ina special meeting held in Minas Gerais nineteen leprologists examined the cases of Dr. CALDEIRA and considered the results he have obtained as "magnifico", in the sense as "unic". This experiment is being continued in various brazilian leper colonies and the Author offers, graciously, his antigen to be tried also in foreing countries.

The writer, as medical director of Father Damien Leper Colony (Ubá, Minas Gerais, Brasil), treated 50 cases of perforating ulcers, from 2 to 40 years of duration, using the antigens prepared with acid-fast bacilli cultures obtained from leprous material by Dr. H. C. de Souza-Araujo. Dosage from 0,12 to 39,35 cm3, injected inside the ulcers, intramuscularly, every 2 to 4 days, accordingly to the patient reaction some of them presenting fever until 41° Centigrade. The result was cicatrization of the ulcers in 92% (46 out of 50) of the patients. The author concluded that the majority of his patients tolerate perfectly the medicine and that its efect was very eficient.

The author gives the clinical records of 20 patients, 14 of which were treated during 17 months, and the rest much less. The method used for treatment was the ecclectical — preferred by the A. since many years —, in which he associates electricity with minor surgery, chaulmestrol (pure or with 0.5 p. c. iodine or 4 p. c. creosote) and other auxilliary curative agents. The chaulmoogra derivatives were used daily as nostrils tamponage (2 p.c. mentholated or thymolated ester), periodically by injections inside the enlarged lymph nodes and nerve abscesses, and twice weekly by subcutaneous infiltrations (MUIR method) 5 c.c. each, and chaulmoogra soap tablets per os. The galvanocauterisation session was once per week, on active leprotic lesions, followed by painting with 30 p. c. trichloracetic acid solution. All 20 patients were bacilliferous before treatment, and became stronger positive after some months treatment. At the end 14 negativated and 6 remained positive and sometimes bacilli being very scanty. 16 out of 20 gave interesting serological reactions, viz.: Wassermann, Stern, Kahn. Rubino, Witebsky and Gaté (Formol-gel) positive in 5; Stern, Rubino. Witebsky and Gaté positive and Wassermann and Kahn negative in 2; Stern. Kahn, Witebsky and Gaté positive and Wassermann anticomplementary in 1; Wassermann. Stern, Kahn, Rubino and Gaté negative in 1. in the beginning, and a few months later Stern. Witebsky and Gaté becoming positive; Stern. Rubino. Witebsky and Gaté positive and anticomplementary W. in 1; Stern, Witebsky and Gaté positive and Wassermann. Kahn and Rubino negative in 1; Witebsky and Gaté positive and Wassermann, Stern, Kahn and Rubino negative in 1; Witebsky 3 times anticomplemantary and strongly positive Gaté in 1; Wassermann and Gaté positive in 1; Stern and Rubino positive in 1 and Stern test negative in one. In 7 cases high Formol-gel were associated with a high sedimentation index. Many cases had very high S.I. being a false measure of the severity of the disease; others remained very high notwithstanding the great improvement of the disease. All patients with more than 12 months treatment became practically symptom free. Lepra reaction amongst them was rare and always started by embolic rash, being controlled by destruction of such skin lesions by galvanocauterisation. In a few cases the lepromata infiltrated with "Subintrol" (a 3 p. c. special chaulmoogra soap prepared by Dr. ASTROGILDO MACHADO) were completely destroyd and never relapsed. In October 1946 Dr. ERNEST MUIR saw here a few cases treated by the author's method and suggested the combination of Diasone with galvanocauterisation which is being done now with satifactory results. The second part of this paper, reporting many leprosy cases treated by the so-called ecclectical method, which are symptom free and negativated since five to ten years, will be published as soon as the sulfone-therapy be summarised in some reliable scientific report to be compared with.

Examination of 267.107 liver specimens obtained in Brazil by viscerotomy during from 1937 to 1946 inclusive revealed 5,953 Schistosoma mansoni infe¬ctions. This represents 2.23% ± 0.019 of the total number of livers studied. Data on the incidence of the disease is tabulated by states and municipios. Infected livers were found in all of the states and territories except the Territory of Amapá. Schistosomiasis is widespread in Brazil with highest incidence in the states of the Northeast. The disease is quite common in EspÃrito Santo and Minas Gerais as well. A study of the age distribution of cases of intestinal schistosomiasis observed among liver specimens obtained in the year 1938 showed a low inci¬dence on young children with a peak of prevalence in the 10 to 19 year age group. The purpose of this contribution is to call attention of the health autho¬rities to the extent and gravity of the problem of intestinal schistosomiasis in Brazil.

In recent speech in Curitiba (May 22nd, 1954), Dr. Mario Pinotti, Director, Serviço Nacional da Malaria, informed that his personnel started on February, 1953, a survey upon chagas Disease in 23 counties of the State of Paraná, South Brazil. out of 895 places surveyed, 678, or 75.7%, were infected by Triatoma infestans klug 1834 and in 234 out of those 678, or 34.5%, this vector was infected by Trypanosoma cruzi. The general natural infection of the insects examined reached 18.86%. The serological survey (Machado-Guerreiro test) was positive in 10.7% of the persons examined in jacarezinho and in 28.3% of those living in Bôa Vista. These data suggested the author to actualise the subject. During his control of severe outbreack of malaria in the North part of Paraná, from march to June 1917 he worked in 8 counties. March 1917 he photographed in Boa Vista four girls, severe cases of chronic malaria, two of which showed bi-palpebral oedema, later on considered by Dr. Pinho Simões (1943) as Romanã syndrome (created in 1935) and Prof. Salvador Mazza (1946) classified as typical cases of Chagas' Disease. now, being elapsed 36 years, the National Service of Malaria confirmed the discovery. The region surveyed was populated, in the beginning of this century, by immigrants from the State of Minas Gerais, from where the author believes that were imported the disease and its vectors. In April 1917 the A. discovered that the old town Jatahy was a big focus of Triatoma megista (now Panstrongylus megistus0. All its 43 houses were strongly infested by such hematophagus and amongst the 200 inhabitants seen many were suspicious cases of chronic cases of Chagas's Disease. In the Indians town (three tribes) of S. Pedro D' Alcantara, situated in front of Jatahy, in the left side of the river Tibagy, there were no Triatomas nor suspicious cases of trypanosomiasis. In 1919 the author started the control of the endemics by destroying the foci of Triatomas and reforming the housing. In 1946 he returned to jatahy and found the sanitary conditions of the town and its inhabitants much better. Climate of the region is favorable to spreading of all tropical diseases, being very suitable one for an extensive sanitary survey. In 1943 Dr. Pinho Simões examined 85 triatomas ( T. infestans) from six counties of the North region and found 40, or 46% infected by Trypanosoma cruzi. The highest incidences were; Joaquim Tavora 74.2% and Carlópolis 26.9%. These counties seem to be infested by Itaporanga county of São Paulo State. in 1953 Serviço nacional da Malária proved that 19 out of 23 counties surveyed were infested by Triatoma infestans. They examined 7,701 of this insect and found 1,453 positive for Trypanosoma cruzi, or 18.9%. in two counties, Jacarezinho and Sengés, were examined 2,588 human bloods, not selected, and 323, or 12.6% of such samples were positive for Chagas' Disease. This year the Malaria Service is doing insects survey in 25 other counties and DDTising infested domiciles of another eight. Such activity is very promising and should be extended to other places.

Em continuação aos estudos dos trematódeos monogenéticos da Coleção Helmintológica do Instituto Oswaldo Cruz, descrevemos no presente trabalho uma espécie do gênero Loimos MacCallum, 1917, Loimolinae Price, 1936, loimoidae Bychowsky, 1957 que consideramos nova para a ciência, e assinalamos nova ocorrência de Tagia ecuadori (Meserve, 1938) Sproston, 1946, Tagiinae Yamaguti, 1963, Diclidophoridae Najibina & Obonikova, 1971, no Atlântico Sul. Loimos scitulus sp. n. diferencia-se das outras espécies do gênero pelos seguintes caracteres: forma e estrututra do proaptor, oótipo grande, número de testÃculos, posição do poro genital, filamento do ovo e forma de opistaptor. Dentre as diferenças dadas Loimos scitulus sp. n. aproxima-se de L. salpinggoides pela estrutura do proaptor, de L. secundus pela posição do poro genital; de L. winteri pelo opistaptor. Quanto aos exemplares de Tagia ecuadori por nós estudados, apesar de ter sido evidenciada uma vagina, identificamos a esta espécie, por apresentar estruturas e medidas que se enquadram nas variações dadas pelos estudiosos do grupo.

São descritos o macho e a fêmea de uma nova espécie de flebotomÃneo - Lutzomyia ramirezi sp. n. - coletada em fenda de rocha em Grão Mogol, Estado de Minas Gerais, Brasil. O macho é caracterizado por apresentar o dististilo com 5 espinhos e o parámero ramificado. A fêmea assemelha-se superficialmente à s fêmeas do subgênero Lutzomyia s. str. porém, apresenta ascóides muito curtos e espinhos extremamente pequenos na parte posterior do faringe. A nova espécie é incluÃda no grupo das espécies "aberrantes ou isoladas" de acordo com Martins, Williams & Falcão, 1978. É também descrita a fêmea de Lutzomyia (Lutzomyia) alencari martins, Souza e Falcão, 1962, coletada na mesma região.
