Postoperative acetylcholinesterase activity in Hirschsprung's disease.

Histochemical staining and biochemical assay of acetylcholinesterase (AChE) activity were applied to rectal suction biopsy tissue from patients treated by Z-shaped anastomosis for Hirschsprung's disease. Postoperative AChE activity and AChE/Total ChE (% AChE) in the rectal anterior wall were significantly higher (p < 0.001) than those in the posterior wall. Biochemical AChE activity was well correlative to visual mucosal AChE activity. It is remarkable that AChE activity in the rectal anterior wall after Z-shaped anastomosis was found to be kept at high level for a long period without any relation to the time interval after the operation, the ano-rectal function, and the recto-anal reflex.

Relationship between protective activity and antigen structure of Haemophilus paragallinarum serotypes 1 and 2.

The object in this investigation was to determine the relationship between protective activity and antigenic structure of Haemophilus paragallinarum, serotypes 1 and 2. A close relationship exists in both serotypes between protective activity and colonial phenotypic form (iridescent and noniridescent). Protective activities of both serotypes were related to a heat-labile, trypsin-sensitive (L) antigen of iridescent form that produced serotype-specific agglutinin to chickens. The chickens having the agglutinins were protected against challenge exposure with homologous strain, but not with heterologous strain. The chickens injected with unencapsulated organisms of noniridescent form that were derived from encapsulated organisms of iridescent form failed to produce both serotype-specific agglutinins and protection against challenge exposure with homologous strain. Most of the chickens injected with serotype 1 strain produced both hemagglutination-inhibition antibody and serotype 1-specific agglutinin, whereas those injected with serotype 2 produced serotype 2-specific agglutinin and protected against homologous challenge exposure. The protective activity was found in saline extract derived from encapsulated organisms of serotype 1, but was absent in those of serotype 2.

Biologic and serologic relationships between Page's and Sawata's serotypes of Haemophilus paragallinarum.

Biologic and serologic relationships between Page's serotypes A, B, and C and Sawata's serotypes 1 and 2 of Haemophilus paragallinarum were investigated. Of the 7 Page's serotype strains testes (which were biologically confirmed as H paragallinarum), serotype B strains Spross and 0222 (which produced a low-iridescent smooth-type colony) required V factor, but did not require chicken serum for growth. Serotype A strains 083, W, Georgia, and Germany and serotype C strain Modesto, as well as Sawata's serotype 1 strain 221 and serotype 2 strain H-18 (which produced a high-iridescent smooth-type colony) required V factor and chicken serum for growth. Strains 083, W, Georgia, and Germany of Page's serotype A and Modesto strain of serotype C, as well as strain 221 of Sawata's serotype 1 and H-18 of serotype 2, had a heat-labile, trypsin-sensitive L antigen. Because serotype A strains had serotype 1-specific antigen and common L antigen, which is shared by serotypes 1 and 2, these strains corresponded to Sawata's serotype 1. Serotype C strain Modesto, which had serotype 2-specific antigen and common L antigen, corresponded to serotype 2. However, serotype B strains Spross and 0222 lacked serotype B-specific L antigen, and were not typeable.

Immunologic relationship between Page's and Sawata's serotype strains of Haemophilus paragallinarum.

Immunologic relationship among Page's A, B, and C and Sawata's 1 and 2 serotype strains of Haemophilus paragallinarum was investigated. In cross-protection tests, two distinct type-specific immunities existed among the strains used. All Page's serotype A strains (083, W, Georgia, and Germany) were immunologically similar to Sawata's serotype 1 strain 221, although serotype C strain Modesto was similar to serotype 2 strain H-18. Cross-protection was not observed between these two serotypes. However, strains Spross and 0222 of serotype B lacked pathogenicity and protective antigenicity.

Congenital pyloric atresia--a report of two cases.

Two cases of the membranous type of pyloric atresia are described and a review of 99 cases reported in the literature is presented. Excision and incision of diaphragm with pyloroplasty was performed on both cases. The first patient was alive following the second operation of gastroduodenostomy for postoperative stenosis. The second premature patient died of sepsis on the 58th postoperative day. The treatment should be surgical and the operative procedure should be chosen depending on the type of atresia. Excision or incision of the diaphragm with pyloroplasty and gastroduodenostomy are the procedures of choice. Gastrojejunostomy should be avoided because of its high mortality rate.

Experimentally induced synovitis of chickens with Mycoplasma synoviae: effects of dexamethasone treatment.

Specific - pathogen - free chickens were inoculated in the right tibiometatarsal joint with a synovitis-derived Mycoplasma synoviae strain before or during dexamethasone treatment. Development of synovitis in chickens inoculated during the drug treatment was apparently delayed in comparison with development of synovitis in non-treated chickens. Severity of clinical synovitis in chickens inoculated before the drug was given was apparently less than that in chickens not treated or in chickens treated with dexamethasone. Histopathologic changes in the early stage of the infection (1 to 2 weeks) were not modified by dexamethasone treatment, although those changes in the succeeding stage (6 to 7 weeks) were greatly lessened. A relationship was observed between the dosage of dexamethasone and the severity of synovitis, as well as the kinds of cells that infiltrated into the joint lesions. Although serum antibody titers in chickens treated with an excessive dose of dexamethasone were markedly lower, clinical, bacteriologic, and histopathologic observations in chickens treated with dexamethasone were similar to those previously found in surgically thymectomized chickens. These results may support the theory that multiple synovitis of chickens caused by M synoviae infection develops mainly because of an immune response, especially by thymus-dependent functions.

Antigenic structure and relationship between serotypes 1 and 2 of Haemophilus paragallinarum.

Antigenic structure and relationship between serotypes 1 and 2 of Haemophilus paragallinarum were analyzed by the rapid plate agglutination and cross-absorption tests. Encapsulated strain forming iridescent colony type of both serotypes 1 and 2 had at least three antigens: heat-labile and trypsin-sensitive (L), heat-labile and trypsin-resistant (HL), and heat-stable and trypsin-resistant (HS). The L was a major antigen located in a surface and divided serologically into three parts: L1, L2, and L3. The L1 was specifici to serotype 1, the L2 was specific to serotype 2, and the L3 was a common antigen shared by serotypes 1 and 2. The HL and HS were common antigens between serotypes. By trypsinization or heating at 121 C, L antigen lost its agglutinability and agglutinin-producing ability. Nonencapsulated organisms forming noniridescent colony type lacked the L antigen. These results suggested that antigenic structure of H paragallinarum serotypes 1 was L1, L3, HL and HS, while serotype 2 was L2, L3, HL, and HS.
