1.Lectin Binding Pattern of the Duodenal Mucosa in the Developing Rat.
Korean Journal of Anatomy 1997;30(5):453-462
For demonstrating the changes of lectin biding pattern in the developing rat, nine biotinylated lectin were applied with ABC method. The affinities for SBA, PNA, RCA-1, sWGA, and Con A were observed on 15 day fetal rat, and an additional UEA-1 affinty on 17 day fetal rat was detected. From the next developing rats, lectin binding pattern was signicantly altered and these changes were greater in suckling rats than others. The notable changes of the duodenal mucosa in developing rats were as follows : A new affinities for SBA, sWGA and UEA-1 in the villous columnar cells and PNA, RCA-1, sWGA and Con A in the crypt columnar cells were detected from suckling rats. The SBA, PNA, BSL-1, RCA-1, sWGA and UEA-1 affinities in the Golgi zone of villous columnar cells showed a tendency to increase from the suckling rats, and a new affinities for SBA, PNA, BSL-1, RCA-1 and sWGA in that of crypt columnar cells revealed from same rats. All lectin affinities used except DBA and Con A were observed in the brush border and maintained a higher level until adults, however, no BSL-1 affinity was detected from the weaning rats. The UEA-1 affinity of goblet cells was detected from 19 day fetal rat and not observed from the weaning rats. And the affinity for DBA and SBA of the goblet cells was demonstrated from the suckling and weaning rats respectively. All lectin affinities examined were observed in the duodenal gland and increased from the suckling rats.

Tamoxifen is a nonsteroidal triphenylethylene delivative that has been widely used in the treatment of breast cancer. tamoxifen is indicated for the adjuvant treatment of breast cancer in women following total mastectomy or segmental mastectomy, breast irradiation and chemotherapy. tamoxifen has been shown to have significant benificial effect in the treatment of breast cancer patient as hormonal therapy. However ,there is mounting evidence that tamoxifen may affect other hormon sensitive organs, including the uterus and ovaries. An increased risk of endometrial polyps, endometrial hyperplasia and adenocarcinoma has been reported in tamoxifen treated women. We have met cases of endometrial polyp and endocervical polyp which were associated with tamoxifen use, after modified radical mastectomy for infilterating ductal carcinoma of breast . So we report these cases with the brief review of literatures.

We report a case of metastatic carcinoma of the skin in 62-year-old male who showed multiple nodules on the anterior chest, scalp, face and left axilla for 2 months duration. He suffered from lower abdominal discomfortness for 6 months. Histopathologic findings revealed atypical cell nests and some tubular or glandular formation in the dermis and subcutaneous fat tissue. Material in the lumen showed diastase resistant and PAS positive, and alcian blue positive at pH 2.4, but negative pH 0.4. So it represented sialomucin. We did not find primary site of malignant tumor. In view of clinical and histopathological findings, it was considered to be originated from the large intestine.

Osteoma cutis is a primary cutaneous ossification, which has no preceding trauma or skin disease and no evidence of Albrights hereditary osteodystrophy n the patient or his family. The lesion appears as hard, round to irregular, sharply defined tumor of varying size within the skin or subcutis, and color ranges from flesh-colored to purple or brown. We report herein a case of osteoma cutis in a 32-year-old female, who had a 1 x 1cm sized, asymptomatic, round, flesh colored, hard nodule on the right side of her forehead for 5 years. Histopathologic examination showed mature bone with many ostocytes, osteoblasts, cement lines and Haversian canals in the dermis.

We present a case of a young female patient with fulminant hepatitis who showed an altered biodistribution of Ga-67, after being scanned twice at 10 month intevals. On initial scan, uptake of Ga-67 was increased in the liver, kidneys, and skeletons. Increased hepatic Ga-67 uptake may be explained by increased transferrin unbound Ga-67 that was taken up by the inflamed liver. The saturation of iron-binding proteins due to multiple transfusions may lead to increased renal and skeletal Ga-67 uptake. On follow-up scan hepatic Ga-67 uptake was markedly increased. Also increased Ga-67 uptake in the axial skeleton and normalized renal uptake were shown. The findings were consistent with iron deficiency anemia. This case demonstrates altered Ga-67 biodistribution associated with multiple transfusions, fulminant hepatitis, and iron deficiency anemia.

9.Lectin Histochemistry on the Surface Mucous Cells, Mucous Neck Cells and Chief Cells in the Gastric Mucosa of Developing Rat.
Korean Journal of Physical Anthropology 1999;12(1):45-54
To localize glycoconjugates of surface mucous cells, mucous neck cells and chief cells in the developing rat, nine of biotinylated lectin(SBA, DBA, PNA, BSL-1, RCA-1, sWGA, UEA-1, Con A and LCA) were applied with ABC method. In the surface and gastric pit epithelium of body of the stomach, DBA affinity was not demonstrated. Although Con A and LCA affinity were slightly increased after birth, these affinities with RCA-1 and sWGA maintained constantly from fetal to adult rat. And UEA-1 affinity gradually increased from the end of suckling period. BSL-1 and PNA affinity showed a tendency to decrease and was not observed in most cells from the suckling and weanling period respectively. In the gastric gland proper, mucous neck cells and chief cells were not distinguished until the early weanling period. All affinities examined except DBA and BSL-1 were observed and increased in the gland of postnatal rat. With the approach of weanling period, more intense affinity for PNA, RCA-1, sWGA and UEA-1 were found on lower portion of the gastric gland proper and more intense affinity for SBA on upper portion. The mucous neck cells showed a similar affinities as gastric gland proper from the weanling period and two affinities for PNA and Con A were detected in the chief cell.

PURPOSE: The authors investigated the ability of cardiac blood pool clearance rates(CBCR) of 99mTc-DiSiDA in the measure merit of functioning hepatocyte mass. MATERIALS AND METHODS: We measured the volume of Iobectomized liver after completion of postoperative scanning with CBCR of 99rnTc-DISIDA in 5 rabbits who the functional hepatic Iobectomy performed by ligation of hepatic artery, portal vein and biliary tracts. Regarding the measurement of CBCR of 99mTc-DISIDA, we set the time which was decreased to the half of the clearance amount of the cardiac radioactivity by hepatic extraction of 99mTc-DISIDA at the point of 50 sec after the renal peak of the radioactivity to prevent confusing with the blood dilution of the radioactivity, that have called DI-K50. RESULTS: The results were followed that the volumes of the functional hepatic Iobectomy in 5 rabbits were 25%, 25%, 41%, 52%, 75% and the residual functioning hepatocyte masses measured by CBCR of 99rnTc-DISIDA were preserved to 75. 1%, 70. 8%, 63. 0%, 52. 2%, 30. 8% respectively. CONCLUSION: we made decision that CBCR of 99rnTc-DISlDA was useful to evaluate the functioning hepatocyte mass.
