PURPOSE: Prenatal diagnosis of congenital heart disease has been made by fetal echocardiography and its clinical impact on the outcome of CHD cases has been analysed. METHODS: A prospective study was performed for the fetal diagnosis of CHD for the standard risk pregnancy, confirmed postnatally or at second study and/or at autopsy and/or follow up at CHA hospital in 2001. Incidence of CHD has been calculated and compared to the incidence of CHD of the prescreening period(1992.3-1995.2). RESULTS: There were 66 cases of CHD prenatally during the study period. CHD consisted of 7 cases of ventricular septal defects(VSD), 7 cases of tetralogy of Fallot(TOF), 5 cases of heterotaxy, 5 cases of double outlet right ventricle(DORV), 5 cases of severe pulmonary stenosis(PS), 3 cases of hypoplastic left heart syndrome(HLHS), 3 cases of coarctation, 3 cases of critical aortic stenosis(AS), 3 cases of pulmonary atresia with intact ventricular septum(PA IVS). Among 66 fetal CHD cases, 30 cases of CHD has been terminated, 1 case died in utero and 23 cases has been delivered at cardiac center through planned delivery. The most common factors of termination were extracardiac and chromosomal anomaly. 17 cases of false negative diagnosis were small VSD and mild PS that couldn't be diagnosed in fetal stage. There was no false positive diagnosis. There were 30 cases of CHDs born in 2001 at CHA hospital. 28 cases were diagnosed postnatally. Among 30 cases of CHDs, there were 18 cases of VSD(17 small VSD), 6 cases of mild PS, 4 ASD, 1 PDA. Incidence rate of CHD in 2001 and period 1992.3-1995.2 were 5.95 and 10.15/1,000 livebirth respectively. CONCLUSION: The data suggested that all of the significant CHDs could be diagnosed prenatally accurately by fetal echocardiography. And the incidence rate of CHD has been decreased by 41.4%. And the most of the complex CHD has been transferred to the cardiac center for planned delivery or has been terminated. The rate of termination was 45.5%.

This study was performed to investigate whethere there is cross-reactivity between Dirofilaria immitis and three intestinal nematodes of dogs. In ELISA, D. immitis-infected dog sera obtained at the 4th molting stage (9-11 weeks) and microfilaremic stage (25-30 weeks) were shown to be highly reactive with crude extract of T. canis. In immunoblotting, some antigenic fractions, 44, 57, 88, 100 kDa of crude extract of T. canis, were found to be positive reaction with sera of dogs infected with D. immitis. However, little or no cross-reaction were observed between sera of D. immitis-infected dogs and crude extract antigen of T. vulpis or A. caninum. These result suggest that there are partial cross reaction between sera of D. immitis-infected dogs and the antigen of T. canis.

The pulmonary microvasculatures of rats were studied by injection replicas prepared from Mercox. This medium enabled us to easily obtain consistent, stable, and complete injected replicas of the pulmonary vasculature. In order to investigate the three dimensional structures of the tributaries of the bronchial artery, such as the capillary plexus and vasa vasorum, we performed a scanning electron microscopic(SEM) study of the vascular casts, using Mercox CL-2B as a media. The alveolar capillaries revealed hexagonal or pentagonal rings of vascular networks. In some areas, the vascular rings composed a square network, The bronchial tree was supplied by the bronchial arteries which form a coarse capillary extending as far as the terminal bronchioles. Occasionally the capillary plexus was connected with adjacent capillary networks in and around the alveolar walls. The walls of the pulmonary artery revealed only a single layer of the vasa vasorum, but those of the pulmonary vein were surrounded by more complicated and well developed vasa vasorum than the pulmonary arterial side. The mean diameters of the venous vasa vasorum are greater than the arterial vasa vasorum.

This study was carried out to investigate the morphologic characteristics and localization of antigenic molecules of Pneumocystis carinii in experimentally induced P. carinii pneumonia in rats. After six weeks of administration of low protein diet and dexamethasone, Sprague-Dawley rats were sacrificed to submit lungs or bronchoalveolar lavage for the study. Monoclonal (092, 900, 902, and 904) and polyclonal (SP-D) antibodies were used for immunohistochemistry and immunoelectron microscopy (ITEM and ISEM). Immunohistochemically P. carinii organisms were well identified as clusters or separated forms in the alveolar spaces being frequently attached to the alveolar walls. Immunoelectron microscopically the adherences of gold particles were observed on the surface of all stages of the P. carinii. Occasionally positive immunogold labeling was observed in the cytoplasm of the trophozoites and on the pellicle of the intracystic bodies within the cysts. The monoclonal antibodies 092, 900, 902, and 904 reacted mainly with pellicles of P. carinii, whereas SP-D labeled on the pellicles, intracystic bodies, cytoplasms of the alveolar macrophages, and free floated surfactant material in the alveolar spaces. The immunogold particles were observed more diffusely and intensely in the cysts than in the trophozoites. These results indicate that antigen is mainly localized on the pellicles, and accumulated during development from the trophozoite to the cyst stages.
