It has long been an accepted policy to employ radiation therapy as initial treatement of choice for most casesof invasive carcinoma of cervix uteri. But, complications following radiotherapy were troublesome problem fot thepatients cured by radiation therapy. The aim of the present study is to present the types and rate of complicationsand to evalute the contributing facors induced the radiation complications. The aim of the present study is topresent the types and rate of complications and to evalute the contributing factors induced the radiationcomplications. 957 cases of invasive carcinoma of cervix uteri receiving radiation therapy were analyzed. Theconclusions are as follows; 1. Bowel complications developed in 96 cases (10.03%). 2. 86% of all bowelcomplications appeared during the first 18 months and most frequently seen after 6 to 12 months(40.03%). 3. Thefrequency of complicaiton was higher in older age and larger irradiation dose, but there is no apparentcorrelation between stage and the occurrence of complications. 4. Portal combination was also a contributingfactor. Highest frequency was noted in AP & PA parallel opposing portals followed by 4 oblique portals and boxtechnique.

A case of supracardiac type of total anomalous pulmonary venous return into the superior vena cava is reported which was successfully diagnosed using spiral CT and three-dimensional image reconstruction. Spiral CT with three-dimensional reconstruction is non-invasive method of visualizing the vascular system and in some instances can replace conventional angiography in pediatric patients.

We examined sixty-three human embryos ranged from three weeks to eight weeks of fertilization age and 117 human fetuses from eleven weeks to fourty weeks of gestational age. Anatomical structure of developing tongue could be classified into eight developmental stages. The first is the sgage of mesial swelling of tongue primordium in the fertilization age of 28~40 days (Streeter stage 13~16), the second is the stage of lateral swelling of tongue primordium in the fertilization age of 41~46 days (Streeter stage 17~18), the third is the sgage of vertical positioning of tongue in the fertilization age of 47~53 days (Streeter stage 19~21), the fourth is the transitional stage of tongue from vertical position to horizontal position in the fertilization age of 54~56 days (Streeter stage 22~23), the fifth is the stage horizontal positioning of tongue in the gestational age of 11 weeks, the sixth is the stage of protrusion of tongue in the gestational age of 12 weeks, the seventh is the stage of maturation of tongue muscle in the gestational age of 7-10 months. The development of tongue papilla characteristically progresses into three stages. The first stage is the epithelial ingrowth for the crypt formation, the second stage is the anatomical formation of vallate, fungiform and filiform papillae, and the third stage is the differentiation of taste buds in the vallate and fungiform papillae or the formation of thick spike-like keratinization at the tip of filiform papilla. We observed that the tongue primordium mainly derived from occipital myotome developed more repidly than other oro-facial structures, so it transitionally occuied the spaces of the pharynx and the posterior nasal cavity, and directly affected the formation of palate and the growth of maxilla and mandible. Whereas the tongue papilla development showed continuous developmental sequences during the fetal period.

Necleolar organizer regions(NORs) ARE LOOPS OF DNA which transcribe to ribosomal RNA by RNA polymerase I. Since NOR-associated proteins are argyrophilic, silver staining method has been used for demonstration of AgNORs. The numbers and/or configurations of NORs may reflect the activities of cells in hyperplastic and neoplastic conditions. To evaluated the applicability of AgNORs in the diagnosis of hepatocellular carcinoma, the author had performed silver staining on the routinely processed, formalin-fixed, paraffin-embedded sections of 14 cases of normal liver(control), 23 cirrhotic liver, and 21 hepatocellular carcinoma. The results are summarized as follows: 1) The mean number of AgNORs per nucleus(mAgNOR) of normal liver, cirrhotic liver and hepatocellular carcinoma was 1.45+/-0.07, 2.53+/-0.38 and 5.52+/-1.63, respectively. The difference of mAgNOR between normal and cirrhotic liver, and between cirrhotic liver and hepatocellular carcinoma was statistically significant, respectively(p<0.01). 2) The percentage of nuclei showing five or more AgNORs per nucleus(pAgNOR) was 0.07% in normal liver, 7.59% in cirrhotic liver, and 60.49% in hepatocellular carcinoma. 3) AgNORs in hepatocellular carcinoma were large, pleomorphic and irregularly clumped, in addition to increase of mAgNOR and high pAgNOR. In conclusion, the increase of mAgNOR, high pAgNOR and large, irregular AgNORs are regarded as an additional helpful finding for the histopathological diagnosis of hepatocellular carcinoma.

Five fetal maxillas were obtained from the autopsy file of fetal postmortem examination, and were examined by serial micro-sections of frontal plane and horizontal plane. Especially the area around the incisive canal of the maxilla was carefully observed. The results are as follows. 1) In 5 fetal maxillas extra-dental laminas and supernumerary tooth germs which are severely malformed in shape are found in the dilated incisive canal, where prominent vessels and nerves are distributed. 2) The supernumerary tooth germs disclose almost normal histo-differentiation of odontoblast and ameloblast, and there shows relatively abundant perifollicular fibrosis in the place of perifollicular bone. 3) It is observed that the over-growth of the extradental lamina from the dental ridge of deciduous central incisor frequently tends to direct toward the incisive canal that includes prominent vessels and nerves.

In order to elucidate the developmental stages of human tooth germ during prenatal period, we examined 254 normal fetuses ranging in gestational age from six weeks to fourty weeks old histologically. Lim's developmental pattern of prenatal tooth germ was divided into three groups, the first group consisting of five grades (I, II, III, IV, V) was for the development of enamel epithelium the second group of three grades was for the deposition of dentin matrix and enamel matrix, and the third group of three grades (A, B, C) was for the growth of perifollicular bone. Some developmental progress between enamel epithelium and dental papilla could be identified by observation of the sequential development of deciduous and permanent tooth germs histologically. The following results were made. 1) The prenatal development of tooth germ showed similar weekly stages in both the maxilla and the mandible. The initial deposition of dentin matrix and enamel matrix (III-1 stage) started at 12-14 weeks of gestational age in the deciduous incisor and canine, and at 16-20 weeks of gestational age in the deciduous molars. And the initial deposition of dentin matrix and enamel matrix in the permanent first molar was at 20-22 weeks of gestational age, and that of the permanent incisor was at 34-36 weeks, and that of the permanent canine was 36-38 weeks, and of the permanent premolar was at 38-40 weeks. 2) The S-shaped curvature was characteristically found where the reciprocal induction of odontoblast and amelobast occurred actively in the developing tooth germ. Primarily pre-ameloblasts which abutted on the dental papilla differentiate the condensed mesenchymal cells into odontoblasts, and secondarily matured odontoblasts which bulged into enamel epithelium produced dentin matrix and differentiated the shrunken pre-ameloblasts into ameloblasts. 3) The mandible grew more rapidly than the maxilla during the early prenatal period. The trabecular bone from both jaws proliferated initially into labial side of developing tooth follicle and gradually circumscribed the tooth follicle lingually and mesio-distally, to form perifollicular bone resultantly.

Larsen's syndrome is a very rare deformity, which is characterized by multiple congenital dislocations with a characteristic facial abnormality. The authors experienced a case of typical Larsen's syndrome that had saddle nose, hypertelorism, high-arched palate, dislocation of the hip joint, subluxation of the knee joint, dislocation of both radial heads, equinovarus deformities of both feet and winged scapulae of both shoulders. The dislocated left hip joint was reduced surgically and the result was excellent.
