The mechanism of development of pulmonary edema associated with -sympathomimetic agent is still not fully understood. 2-sympathomimetic drugs such as ritodrine, terbutaline, and fenoterol are widely used for the treatment of premature uterine contraction. We describe a case of pulmonary edema that occurred suddenly during Cesarean section in a previously healthy parturient, associated with ritodrine pretreatment for 5 days in an attempt to arrest preterm labor. Pulmonary edema was completely treated with mechanical ventilation and diuretic therapy.

It is widely blieved that the new bone formation is provoked by fine electrical stress to bone. There have been maay experimental studies that showed much efforts to define these small amounts of electricity, and these fine electricities are being used in the orthopedic field for the treatment of various fractures, nonunions and pseudsrthrosia The auther has checked the electrical potentials changing in the course of fractvre hesling in rabbits femur. Comparing these data with that of the normal control group, the following results were obtained. 1. In the normal rabbit's femur the electrical potentisl was 13.6mV less on the concave side than on the convex side. This finding can be explained by the existence of stress generated potential or piexoelectricity. 2. Electrcal potentials on the fractured femoral sites were lowered significantly from that of the control group. So auther could confirm the existence of bioelectrical generated by increased electrical activity of the living bone. 3. The electrical potential of the fractured femoral site has been decreased 50% and 20% as low as that of the normal site at 8 weeks respectively. It is expected that these lowered electrical potentials may become dose to the normal values when the changed metabolic process due to the fractured bone is no longer functioning and it is believed to take human 2 years to get the normal value.

Poland's syndrome is congenital anomaly which was described first by Alfred Poland in 1841. The clinical features are variable but always include congenital aplasia of fingers and syndactyly. We have experienced a case of Poland's syndrome. This case was male children and revealed thoracic anomaly of right side (absence of pectoral muscles and anterior axillary fold), atrophy of forearm muscles, ipsilateral syndactyly with aplasia of thumb and middle phalanges of 2, 3, 4, 5,th fingers, and ipsilateral congenital radio-ulnar synostosis.

The human oral mucosa has noncornified lining epithelium, cornified masticatory epithelium, and complex epithelium. The epithelium of human tongue shows diverse morphological variations from one site to another, and conflicting reports exist in the literature concerning the type of lingual epithelium. Cytokeratin[CK] have been shown to characterize different type of epithelia. In the present study to clarify intermediate filament patterns of tongue mucosa and lingual gland in human fetus from second trimester of pregnancy and adult, cytokeratin expression was investigated immunohistochemically using antibodies for cytokeratins in the dorsal surface of tongue, taste bud, and lingual gland, and comparison with the expression between fetus and adult was made. The epithelium of the fetal lingual papillae consisted of 4 to 6 layered stratified cells, and that of the inferior surface of tongue consisted of 6-8 layered stratified cells in PAS-hematoxylin stain. The lingual gland was well differentiated and the alveolus was strongly positive to PAS reaction. The dorsal surface of the adult tongue was composed of lingual papillae. The papillae was covered by keratinized stratified squamous epithelium and interpapillary area by nokeratinized epithelium in hematoxylin-eosin stain. The taste bud was present in the fungiform papilla. The lingual gland appeared among the muscle layers near the inferior surtace and was composed of mucous and serous cells. By immunohistochemical stain, the epithelium of the lingual papillae exhibited various staining-intensities for cytokeratin antibodies, and showed same staining patterns bosh epithelium in tip of papilla and interpapillary area in fetus. However, the dorsal epithelium of the adult tongue showed different staining patterns between tip of the papilla and interpapillary area. In fetal lingual papilla CK7 and CK8 were expressed in superficial cells, AE8 in intermediate and superficial cells, CKl4 in basal cells. MNFI116 and AE3 showed a strong reaction in basal and suprabasal cells. The epithelium of the inferior lingual surface reacted positively with AE8 and CK14, MNF116, and AE3. CK7 and CK8, however, were not reacted. In adult lingual papilla CK10 was expressed in superficial cells of the tip of the papilla, AE8 in suprabasal cells of interpapillary epithelium, CKl4 in basal cells of papillary and interpapillary epithelium, CKl9 in superficial cells of interpapillary epithelium, MNFI116 and AE3 in suprabasal cells of papillary and interpapillary epithelium. However, CK7, CK8, CK18, and 5D3 were not expressed in the epithelium of the dorsal tongue. The cells of taste bud in fetus showed positive reactions for CK7, CK8, MNF116, and AE3, but negative reactions with CK10 and AE8. The cells of taste bud in adult were stained with CK7, CK8, CK18, and MNF116, but not stained with CK10 and AE8. In lingual gland of fetus, CK7, CK8, CKl8, 5D3, MNF116, and AE3 were expressed in alveolar cells. Only CK10 gave a negative staining in ductal cells. The mucous cells of the adult lingual gland were reacted with CK7, CK10, CK18, CK19, and MNF116, and the serous cell with CK7, CK19, and MNF116. The ductal cells of the adult lingual gland were stained with CK7, AE8, CK18, CKl9, 5D3, MNF116, and AE3. CK14 was expressed in the cells of intralubular ductule, not in the ductal cells. By electron microscopy, the epithelia of both dorsal and inferior lingual surfaces in fetus consisted of nonkeratinized stratified squamous epithelium. A cell with clear cytoplasm and some dense granules was noted among the basal cells. These results indicate that the epithelium of fetal lingual papillae is non-keratinized type and the epithelium of the papillary tip is keratinized type and interpapillary epithelium is nonkeratinized type in adult, and suggest that the superficial cell containing cytokeratins 7 and 8 in dorsal lingual epithelium of fetus has a similar role to the periderm of fatal skin.

Paraneoplastic pemphigus is a distinct and rare autoimmune disease characterized by extensive and painful mucosal ulcerations and polymorphic desquamated skin lesions in the setting of an underlying neoplasm, typically of lymphoreticular origin. Thus difficulties in the management of anesthesia can be expected. A 66-years-old man was scheduled for removal of intraabdominal sarcoma associated with paraneoplastic pemphigus. Physical examination showed multiple erythematous bullae, crusts, plaques and target-like lesions on the whole body and desquamated erythematous skin lesions on the back and extremities. In the operating room, his right femoral artery was cannulated with a 20 G, 12.7 cm CVP catheter and left femoral and subclavian veins with 14 G, 20 cm CVP catheters, respectively. After application of 4 % lidocaine spray, his oropharynx and supraglottic area were evaluated under direct laryngoscopy and revealed multiple ulcerations on oral mucosa, but no distinct lesion on supraglottic area. Anesthesia was induced by rapid-sequence method with fentanyl, thiopental sodium and succinylcholine followed by endotracheal intubation. The endotracheal tube was held by a roll gauze around the neck and its cuff was minimally inflated to avoid overpressure against his tracheal wall. After the end of surgery, his oral cavity was suctioned with no remarkable bleeding, and tracheal wall including cuff-contacted area was evaluated under fiberoptic bronchoscopy, revealed intact wall without any bulla or ulceration. The patient was transferred to intensive care unit for proper postoperative management after extubation of endotracheal tube.

It is highly desirable to achieve optimal reproductive performance, reliable morphological and physiological basic data of the reproductive organs. Therefore, seasonal changes in serum testosterone, LH, and FSH concentrations, and morphological changes in testicular epithelial cells were studied in the Korean native pheasant throughout the annual cycle. Mature male pheasants[14-16 months after hatching] were used in this study. The general morphological changes of the epithelia of the seminiferous tubules were observed by dibasic stain, and semithin section from Epon blocks with a phase contrast microscopy. The ultrastructural changes of the the epithelia of the seminiferous tubules were investigated by ultrathin section with transmission electron microscope. The changes in the profiles of the serum FSH, LH, and testosterone concentratioins were measured by RIA[radioimmunoassay]. The results obtained are summarized as follows : 1. There was little variation in the average diameter of the seminiferous tubules from autumn[67.13+/-5.95micrometer] to winter[68.59+/-6.07micrometer], but the highest levels were reached in spring[192.78+/-41.58micrometer]. Thereafter, the diameter decreased slowly in summer[146.57+/-43.68micrometer], then decreased significantly in autumn[67.13+/-5.95micrometer]. 2. Serum testosterne concentration was low from autumn[13.+/-7.21ng/100ml] to winter[17.39+/-13.75ng/100ml], but the highest levels were reached in spring[127.72+/-66.47 ng/100ml]. Thereafter, the concentration was lowest in autumn[13.+/-7.21ng/100ml]. 3. Serum LH concentration increased slowly and linealy from autumn[5.04+/-1.04ng/100ml] to winter[6.23+/-1.08ng/100ml], but the highest levels were reached in spring[11.3+/-3.6 ng/100ml]. Thereafter, the concentration reached the lowest level in autumn[5.04+/-1.04 ng/100ml]. 4. Serum FSH concentration was low from autumn[4.65+/-0.63ng/100ml] to winter[4.2+/-0.98ng/100ml], but the highest levels were reached in spring[17.41+/-8.35ng/100ml]. Thereafter, concentration was the lowest in autumn[4.65+/-0.63ng/100ml]. 5. The seminiferous tubules showed the onset of the spermatongenic cycle in spring but the seminiferous tubules collected in summer exhibited partially degenerative changes. 6. The cytoplasmic process of Sertoli cells of the seminiferous tubules of the pheasant were collected in summer. Many vesicles and degeneratiye changes were included but many number of spermatozoa were embedded partially in the multivesicular bodies in these processes. 7. The diameter of the seminiferous tubules of the pheasant narrowed markedly in autumn, and atrophied in winter. The spermatogonia and Sertoli cells were arranged in monolayer. 8. The myelin figures in the cytoplasmic process of Sertoli cells of the seminiferous tubules of the pheasant in autumn. The nucleus of the Sertoli cells were of a round configuration elongated and oriented perpendicularly to the basement membrane. The results obtained provide basic data for reproductive physiology and are useful for studying the male genital organs of the Korean native pheasant. Structural changes of the seminiferous epithelial cells significantly and postively correlated with serum FSH, LH. The correlation of changes in the hormonal status with alterations of Sertoli cell organells precedes the breeding season.
