Background: We investigated surgical outcomes after the surgical repair of cor triatriatum sinister (CTS). Methods: Thirty-two consecutive patients who underwent surgical repair of CTS from 1993 through 2020 were included in this study. The morphological characteristics, clinical features, and surgical outcomes were described and analyzed. Results: The median age and body weight at operation were 9 months (interquartile range [IQR], 3–238 months) and 7.5 kg (IQR, 5.8–49.6 kg), respectively. There were 16 males (50%). According to the modified Lucas classification, type IA (classical CTS) was most common (n=20, 62.5%). Atrial septal defect was associated in 22 patients (68.8%) and anomalous pulmonary venous return in 8 patients (25%). Pulmonary hypertension was preoperatively suspected with a high probability in 18 patients (56.3%). There was 1 early death (3.1%) after emergent membrane excision and hybrid palliation in a high-risk hypoplastic left heart syndrome patient. There were no late deaths. The overall survival rate was 96.9% at 15 years post-repair. No early survivors required reoperation during follow-up. Most survivors (31 of 32 patients, 96.9%) were in New York Heart Association functional class I at a median follow-up of 74 months (IQR, 39–195 months). At the latest echocardiography performed at a median of 42 months (IQR, 6–112 months) after repair, no residual lesion was observed except in 1 patient who had moderate pulmonary hypertension (mean pulmonary arterial pressure of 36 mm Hg). Conclusion: Surgical repair of cor triatriatum could be performed safely and effectively with an extremely low risk of recurrence.

The oogenesis and ultrastructure of fertilized egg envelope of false dace were investigated by light and electron microscope. The cytoplasm of false dace oogonia was basophilic and many nucleoli were located at inner side of nuclear membrane. In primary oocytes, yolk vesicles were distributed in marginal area only and egg envelope was not formed on egg outside. In secondary oocyte, the egg envelope was formed and yolk vesicles were increased than that of early stage in cytoplasm. The amount of basophilic substance was decreased. In case of matured egg, thickness of egg envelope and site of egg were increased, basophilic substance was distributed in egg envelope around only. The yolk vesicles were changed to yolk mass in accordance with development. The fertilized egg was of ellipsoidal, adhesive type and yellowish, have a single micropyle in the area of the animal pole. The fertilized egg envelope consisted of three layers, an outer adhesive layer, a middle layer consisting of 6 lamellae alternating layers and an inner electron dense layer. An outer surface of the fertilized egg envelope was arranged by adhesive fibrous structures. In conclusion, it is summarized that the oogenesis of false dace were the increase of cell size, the formation and accumulation of yolk, and decrease of basophilic intensity in cytoplasm. These ultrastructural characteristics of fertilized egg envelope from false dace can be utilized in taxonomy of teleost.

This study has been conducted to investigate flow characteristics of a micropump with piezoelectric materials. In this study, the change of flow rates has been investigated for different positions of the inlet and outlet and for different distances between them. The FSI(Fluid Structure Interaction) method has been employed for numerical analysis of the piezoelectric diffuser/nozzle based micropump. It has been found that time averaged flow rate is greater in the case that distance between the inlet and outlet is longer. For the cases where the positions of the inlet are different with the position of the fixed outlet at the center, the flow rate is increased as the inlet is located farther from the center. This study may supply fundamental understandings for the design and analysis of the prototypes of piezoelectric micropumps.

Kribensis, Pelvicachromis pulcher is a teleost belonging to Cichlidae. The oogenesis was investigated by light microscope. The ovary was located between intestine and air bladder, a yellowish and ellipsoidal shape with the major axis 20mm and the minor axis 5 mm. Cytoplasm of oogonia in early stage was basophilic and many nucleoli were located at inside of nuclear membrane. In primary oocytes, yolk vesicles were distributed only in the marginal area and egg envelope was not formed on the outside of an egg. In secondary oocytes, the egg envelope was formed and yolk vesicles in the cytoplasm were increased than the earlier stage. The basophilic substance of cytoplasm was changed to acidic. Some yolk vesicles started forming small yolk mass except the surrounding nucleus. In case of matured egg, size of egg were increased. The yolk vesicles were changed to yolk mass in accordance with development. The yolk mass contained crystal-like structures. In conclusion, the oogenesis of Pelvicachromis pulcher was summarized by the increase in cell size, the formation and the accumulation of yolk, and the decrease of basophilic substance in the cytoplasm. The oogenesis of Coreoleuciscus splendidus is similar with other teleost. But there were differences in distribution of yolk vesicle and yolk mass containing cristal-like structures.

Coreoleuciscus splendidus is a teleost belonging to Gobioninae, Cyprinidae. The oogenesis was investigated by light microscope. The ovary was located between intestine and air bladder, a grayish and ellipsoidal shape with the major axis 20 mm and the minor axis 5 mm. Cytoplasm of oogonia was basophilic and many nucleoli were located at inside of nuclear membrane. In primary oocytes, yolk vesicles were distributed only in the marginal area and egg envelope was not formed on the outside of an egg. In secondary oocytes, the egg envelope was formed and yolk vesicles in the cytoplasm were increased than the earlier stage. The basophilic substance of cytoplasm was changed to acidic. In case of matured egg, thickness of egg envelope and size of egg were increased. The yolk vesicles were changed to yolk mass in accordance with development. In conclusion, the oogenesis of C. splendidus was characterized by the increase in cell size, the formation and accumulation of yolk, and the decrease of basophilic substance in the cytoplasm. The oogenesis of C. splendidus is similar with other Cyprinidae fishes. But further study on ultrastructural study of fertilized egg envelope will be necessary to get the species specificity.

The ultrastructure of spermatogenesis and sperm in Chinese minnow, Rhynchocypris oxycephalus belonging to Leuciscinae was investigated by light and electron microscopes. The whitish testis was located between intestine and air bladder. The size of testis was major axis 2.3 cm, minor axis 6 mm. The testis contained numerous testicular cysts, and spermatogenesis was non-synchronized in these testicular cysts. In the case of spermatogonium, the nucleus was comparatively large ellipsoidal, and mitochondria showed a marked development. The size of primary spermatocyte was smaller than that of spermatogonia, and secondary spermatocyte was smaller than primary spermatocyte. The chromatin of spermatocyte was highly condensed according to their development. The nucleus with electron-dense was round shape. In spermiogenesis, flagella started to be formed and chromatin was more condensed. The mitochondria were rearranged in a middle piece. The sperm was formed by loss of cytoplasm. The head of mature sperm was a spherical shape and have not acrosome. The microtubules of flagella were arranged 9+2 structure. Also, the tail of sperm have not lateral fins.

Saengshik which is food not to apply heat is expected to have good effect on the body because metabolic enzymes are preserved in it. In fact, despite of enlargement of saengshik market, the researches on the effect of saengshik are insufficient. So, the aim of this study was to investigate the protective effect of saengshik against $CCl_4-inducing$ hepatotoxicity in ICR mice. As the result of serum biochemical parameters, AST (SGOT) and ALT (SGPT) were significantly decreased at the experimental group treated with saengshik and $CCl_4$ as compared with experimental group 1 treated with $CCl_4$ only (p<0.01). ALP was significantly higher at experimental group 2 compared with control and experimental group 1 (p<0.01). In histological study, experimental group 1 treated with $CCl_4$ only showed severe necrosis all over the liver at the gross observation, and showed severe perivenular necrosis and individual hepatocytic degeneration. However experimental group 2 was not nearly different from control group in appearance and showed mild perivenular necrosis and dominant sever neutrophil infiltration surrounding central veins. The result of this study showed the protective effect against $CCl_4-inducing$ hepatotoxicity and suggest the possibility of the functional health food. However, further studies about the effect of saengshik may be needed.
