    Notes: Abstract We measured anti M protein antibody (AMPA) titres in children with idiopathic mitral regurgitation (MR), streptococcal infection, rheumatic fever (RF), post-streptococcal acute glomerulonephritis (AGN) and normal healthy children. We investigated the association of MR with streptococcal infection and whether high AMPA titres can be used as persisting evidence of previous streptococcal infection. AMPA titres were measured with an enzyme-linked immunosorbent assay. We found significantly higher antibody titres in patients with MR and in streptococcal infection, RF, and AGN than in healthy controls. In the MR group (n=15), 54% patients had AMPA titres above the 90th percentile value that was found in normal controls. An elevated AMPA titre persisted for a long period even when the anti-streptolysin O titres had declined to normal in RF patients. Our data suggest that the high AMPA titres in MR should be further investigated to clarify the probable association with previous streptococcal infection. Conclusion High AMPA titre is a risk factor for developing complications after streptococcal infection. Our serological evidence suggests that in some patients. MR may be related to previous streptococcal infection.

    Notes: Abstract Recently, a possible relationship between Kawasaki syndrome (KS) and superantigen has been discussed since the report of selective expansion of specific Vβ family in the acute phase of KS. To further investigate the relationship between KS and superantigens, we examined 25 types of T-cell receptor Vβ family repertoire in patients with KS using the reverse transcription polymerase chain reaction. This is the first attempt to examine all of 25 Vβ families in KS. A non radioisotope method was used to quantify mRNA so that the experiment was safer, simpler, and faster. An expression index (EI) for each Vβ was defined as: (the amount of each Vβ mRNA)/(the sum of all Vβ mRNA) × 100. Ten patients with KS and ten normal children were studied. The Vβ9 and Vβ15 of acute phase of KS showed both significantly lower mean EI and significantly higher frequency of a decreased EI value as compared with control children. Selective expansion of the Vβ family in the patients with KS was not observed. Although highly increased EIs were observed in various Vβs, their frequency was not statistically significant. The pattern of increased Vβs did not show the specific pattern that indicates a particular superantigen. Conclusion In Kawasaki syndrome non-radioisotope method for analysing Vβ mRNA is useful in cases where many samples have to be handled. The depletion of Vβ9 and Vβ15 or highly increased expression index in the acute phase of Kawasaki syndrome might suggest a relationship to superantigens.

    Factors affecting female-biased sex ratio in a trap-nesting wasp, Trypoxylon malaisei (1999)

    Notes: Abstract We examined the female-biased sex ratio of a trap-nesting wasp Trypoxylon malaisei considering the following factors: (1) local mate competition (LMC), (2) resource quality, (3) partial bivoltinism, and (4) presence of constrained females. The sex ratio (expressed as male ratio) at emergence was strongly female biased, i.e., 0.30 and 0.19, in terms of the number and investment, respectively. To evaluate the primary sex ratio, we analyzed the data from nests where all the offspring successfully emerged, excluding nests composed of single-sex offspring. The primary sex ratio was also female biased, at 0.33 and 0.21, in terms of the number and investment, respectively. LMC was highly responsible for the female-biased sex ratio because both the nonrandom oviposition sequence [females at inner cells and male(s) at outer cells] and earlier emergence of males allowed sib-matings to occur. In contrast, the other three factors little affected the female-biased sex ratio: the sex ratio was fairly constant when resource quality (nest size) varied, partial bivoltinism was extremely rare or absent, and constrained females were absent or did not reproduce at all.

    Relationship between the degree of injury at operation and the change in antimyosin antibody titer in the postpericardiotomy syndrome (1994)

    Notes: Summary Successive measurements of cardiac myosin light chain I (MLC), creatine kinase isoenzyme MB (CKMB), and the titer of antimyosin antibody (AMA) were performed prospectively in 19 patients following open heart surgery. Seven of these patients showed the postpericardiotomy syndrome (PPS). No differences in serum concentrations of MLC or CKMB were observed between the patients with and without PPS, and all patients in both groups had abnormal MLC values after surgery. However, only patients with PPS had significantly elevated AMA titers. The maximum AMA titer was significantly correlated with the severity of the effusion. These data suggest that PPS is unrelated to the severity of myocardial injury during operation. Furthermore, the AMA titer may be useful as one of the indicators for determining the patient's clinical condition.

    A Case of Marfan Syndrome in an Adolescent with Aortic Dissection: Should the Recommendation for Surgical Intervention Be Changed? (1999)

    Notes: Abstract. We present a 15-year-old male patient with Marfan syndrome who died suddenly of aortic dissection and rupture. The commonly used criteria for elective aortic root replacement are an aortic root dimension 〉50 mm or an aortic dimension more than twice the normal predicted value. He did not fulfill these criteria. His ascending aortic dimension 17 days prior to his death was 48 mm and the aortic dimension to the predicted value was 1.8, although he showed progressive dilatation of the aortic root. A ratio of the ascending aortic dimension of more than 1.5 times that predicted, as proposed by Pyeritz, and a considerable increase in aortic dilatation beyond previous observations may lead to timely surgical repair.
