Endometrial ossifications in seven patients who presented with secondary or primary infertility were described. Herein, we described step-by-step bone forming process in the endometrium and we compared the clinicopathological features of metaplastic ossification and fetal remnants. In five of seven patients, metaplasia was unquestionable etiology of ossification, which was ocquired in the healing process of postabortion endometritis. Ossifications were recurred during the follow-up periods after total hysteroscopic removal in 2 cases. Three cases were followed by normal pregnancy, after total hysteroscopic removal of bony spicules in 2 cases and with retaining of bony spicules in 1 case. In one other case, bony spicules of fetal remnants were verified by multiple fetal hair shafts and endochondral bone formation. Therefore, the cause of endometrial ossification can only be determined by histological findings and careful past obstetric history.

Clear cell sarcoma of tendons and aponeuroses is the term coined by Enzinger in 1965 to describe a rare but unique type of soft tisse neoplasm whose cells characteristically have the capacity to produce melanin. The authors experienced a case of 64-year old female who presented with a 6x5x4 cm sized mass deeply seated in the left popliteal fossa. The mass was firm and multinodular, and on cut section revealed patches of brown black pigmentation. Histologically the tumor was composed of round to fusiform cells with clear or pale eosinophilic cytoplasm that contained small amounts of glycogen, separated into compact nests or short fascicles by delicate septa of fibrous tissue. The brown black pigment seen in tumor cells and stroma was proven to be melanin by special stain, and ultrastructural examination showed melanosomes in varying stages of development dispersed freely in the cytoplasm or in the lysosomes. These findings strongly support the view that clear cell sarcoma is a tumor of neural crest origin rather than of tenosynovial mesenchyme origin, and is a soft tissue variant of malignant melanoma.

The clinical effect of etafenone on 12 cases of angina pectoris(9 males and 3 females with average age of 58.3 years) were studied and following results were obtained: 1. Anginal chest pains were improved after average 9 days (3~15 days) of medication and the dreug was very effective in 41.7%, moderately effective in 33.3% and slightly effective in 25.0% of cases. 2. The ST segment depression of E.C.G. were reduced in 50.0%, improvement of T waves inversion or enlargement of T waves were observed in 66.7% and E.C.G. improvement either ST segment or T wave observed in 75.0% of cases. 3. No side reactions such as hypotension, palpitation, dizziness, headache or gastrointestinal disturbances were seen during the treatement with etafenone.

This case report describes a patient with semipedunclated granuylar cell tumor(granular cell myoblastoma) of the proximal ascending colon removed by endoscopic polypectomy. A 39-year old femalie was visited to our hospital for intermittent abdominal pain and loose stool. Colonoscopic examination showed a semipedunclated lesion covered with yellowish white smooth mucosa in the proximal ascending colon. The tumor was removed by endoscopic polypectomy. The collected specimen was 0.9x0.8 cm in size. The cut surface of the specimen showed a white round firm tumor covered with mormal epithelium of the colon. Using immunohistochemical study, the tumor cells were to be positively stained by S-100 protein and negatively stained by desmin, which supports the concept of the Schwann cell origin of granular cell tumor. In Korea, 2 cases of granular cell tumor of the colon and rectum, which were treated by surgical removal, have been reported. This case in the first endoscopic polypectomy of granular cell tumor of the colon and retum in Korea. The endoscopic polypectomy is thought to be useful for the therapy of small pedunclated or semipedunclated granular cell tumor, intracolonic type.

Luteal phase defect (LPD) is an ovulatory disorder of considerable clinical importance that leads to delayed endometrial maturation and inadequate endometrium for blastocyst implantation. This disorder is implicated in infertility and recurrent spontaneous abortion. We analyzed the endometrial histological maturation, and the estrogen receptor(ER) and progesterone receptor(PR) status in patients with unexplained delayed ovulation, and in patients with ovulation induction by clomiphen citrate. The purpose of this study was to determine whether the length of the follicular phase influences the endometrial histological maturation and the hormonal receptor status, and to know the effect of clomiphen citrate on the endometrium. In the delayed ovulation group, the endometrium was characterized by an irregular outpouching and dilated lumina of the glands, a decreased secretory activity and predecidualization, and a decreased number of granulocytes in the stroma. In the clomiphen citrate-ovulation induction group, glandular proliferation was markedly diminished with poorly convoluted and narrow glands, secretory activity was decreased, stroma was undecidualized, and there was an absence of granulocytes. ER expression was increased in the glandular epithelium in the delayed ovulation group, and both ER and PR expressions were markedly decreased in the glandular epithelium and stromal cells in the ovulation induction group. Endometrial maturation and differentiation may be diminished by increased estrogenic and relatively deficient progesterone effects in patients with delayed ovulation. The hormonal receptor status might also be influenced by hormonal changes. Clomiphen citrate successfully induced ovulation in patients with delayed ovulation, however, endometrial proliferation and maturation were markedly suppressed. This might be related to the lower pregnancy rate and higher abortion rate in patients with clomiphen citrate induced ovulation.

BACKGROUND: UVB is responsible for most of the carcinogenic effects of sun exposure. OBJECTIVE: Aim of this study was to investigate the regulation and intracellular redistribution of p53 protein after UVB irradiation. METHODS: Cultured normal human melanocytes and G361 melanoma cells were used for west-ern blotting and confocal microscopic examination for determining expression and distribution of p53. RESULTS: UVB irradiation increased p53 expression in cultured normal human melanocytes and G361 malignant melanoma cells according to increasing doses of UVB. Furthermore, p53 moved from cytosol to nucleus after UVB irradiation. CONCLUSIONS: UVB irradiation induced overexpression and redistribution of p53 in cultured normal human melanocytes and G361 malignant melanoma cells.

Embolization of a carotid cavernous fistula(CCF) by means of a detachable balloon is a well-established method for treating CCFs while preserving a patent parent internal carotid artery(ICA). However, failure to embolize the CCF may occur on a few occasions. Herein we describe a stent-assisted Guglielmi detachable coil embolization that completely occludes the fistulous opening rather than fills the cavernous sinus. By applying this technique, we successfully treated a CCF, without compromise of the parent ICA in patients who has failed with balloon technique previously.
