The pathologic features of acute corrosive esophago-gastritis by ingestion of "Trapunc", a common commercial drain cleansing liquid, is presented. A 37-year-old woman ingested abut 30 ml of Trapunc (3 gm NaOH/100 ml) to commit suicide and received piecemeal esophagectomy and total gastrectomy 9 days after the episode. The esophagus and stomach were extremely friable and necrotic. The most part of the stomach showed acute toxic necrotizing gastritis which was manifested by extensive greenish brown discoloration due to liquefaction necrosis of the mucosa except for a few rugae along the greater curvature. The antrum and distal body revealed severe mucosal detachment and even transmural necrosis. The tissue reaction was basically the same as those of NaOH-induced corrosive esophago-gastritis of acute stage, although it appeared to be severer probably due to sodium hypochlorite, and additive constituent of the ingested cleanser. A unique distribution pattenr of mucosal involvement is discussed.

The functional and morphologic cardiac developments are determined by the morphogenesis, growth and remodeling of the heart resulted from the cell proliferation and apoptosis. We studied the distribution of the proliferation and apoptotic activity of myocardial cells according to the developmental stages in embryos of C57bl/6 mice. Serial histologic sections were stained with PCNA and TUNEL method and were analyzed with image analyzer (BMI, Seoul). The ventricular myocardium of an embryonic heart could be divided into trabecular, inner compact and outer compact layers. Proliferation indices at layers of the left ventricular myocardium on embryonal days (ED) 13, 14, 16, 17 and 18 were 19.9%/47.4%/60.4%, 16.1%/45.8%/60.3%, 24.6%/45.6%/38.1%, 23.3%/17.7%/18.3% and 31.2%/28.0%/19.4% (trabecular/ inner compact/ outer compact) and the right ventricle, 11.0%/34.4%/60.5%, 23.0%/44.0%/69.0%, 29.2%/42.9%/35.1%, 30.4%/30.5%/22.3% and 32.4%/28.4%/16.3%. The apoptotic indices of the left ventricle/VIF were 0.23%/3.66% on ED 13-14, 0.42%/1.31% on ED 16 and 0.05%/0.60% on ED 17-18. The results show that the proliferation of the myocytes was maximal at the outer compact layer on ED 13 and 14 but lowest on ED 17 and 18. This decrease was more pronounced at the left ventricle. The innermost trabecular layer showed a constant proliferation activity of 11.0-32.4%. The presence of spatiotemporal differences in the cell proliferation reveals regional regulation in the developmental timing of cardiac development. Functional maturation is considered to be responsible for the change of proliferation activity. The apoptosis was most frequent and intense in the VIF and crux throughout the periods of each embryonal day where as rarely seen in the ventricular myocardium, especially in the trabecular layer of myocardium. These findings suggest that the apoptosis plays the role in the development of atrioventricular, ventriculoarterial septation and valve formation. Our results also reveal that the participation of apoptosis in formation of the trabeculation can be denied.

BACKGROUND: The purpose of this study was to investigate the correlation between yoga and autonomic nervous system in women with metabolic syndrome. METHODS: A randomized controlled study was performed in participants recruited from a public center for managing chronic diseases located in Gyeong-gi Province. The 39 women participants diagnosed with metabolic syndrome were randomly assigned to the 12-week yoga exercise group (n=22) or the wait-listed control group (n=17). Biochemical laboratory tests and heart rate variability were measured before and after the 12-week program. RESULTS: In post-menopausal women, the low frequency power of frequency domain significantly decreased in the yoga exercise group compared to the control group (P=0.07). On the time domain of heart rate variability and metabolic syndrome components, there were no significant differences between the groups. CONCLUSIONS: Sympathetic activity was decreased in post-menopausal women with metabolic syndrome who practiced yoga. Our results suggest that yoga might be beneficial in improving the autonomic nervous system in post-menopausal women with metabolic syndrome.

Obstructive jaundice of the bile duct resulting from tumor-producing copious, thick mucin, causing ductal obstruction and dilatation, has been reported very rarely. Also, the benign bile duct neoplasm is extremely rare. We report a case of a mucin-secreting villous adenoma of common hepatic duct causing obstructive jaundice and cholangitis. The patient was a 72-year-old male and had a 3 yeared history of common hepatic mass unchanged remarkably in size. The abdominal ultrasonogram and computed tomography revealed well circumscribed, more than 2cm sized mass on the CHD and ductal dilatation. We were able to get an interesting cholangioram showing irregular, nodular, ill defined filling defect in the extrahepatic bile duct, different from US and CT findings, And it was just caused by thick, copious mucin from the tumar. This case was confirmed as mucin-secreting villous adenoma after surgery.

BACKGROUND: The large surfaces of the skin are often initial site of contact between microorganism and human. The skin are coated with epidermis and epithelial cells can recognize microorganism and mount a fast defense through the production of various inducible antibiotic peptides. This leads to chracteristic broad spectrum of antimicrobial activity against bacteria, fungi, and viruses. Recent studies introduce us new peptides with antimicrobial activity such as P,-defensins and cathelicidins. They are expressed on the epithelia and polymorphonuclear leukocytes, which are first lines of defence from various invasive environments. Futhermore, they are considered very interesting and important endogenous antibiotics. Our previous study has shown that the expression of human defensin(hBD-2) mRNA, which is potent antibiotic peptide against Gram-negative bacteria(P. aeruginosa), was upregulated with ultraviolet(UV) irradiation, tumor necrosis factor-α(TNF-α) and lipopolysaccharide(LPS) in HaCaT cells. A novel hBD-3, 5-kDa, nonhemolytic antimicrobial peptide, was demonstrated a salt-insensitive broad spectrum of potent antimicrobial activity against many potentially pathogenic microbes in especially, multiresistant S. aureus. We have analyzed the expression patterns of hBD-3 in HaCaT cell lines. OBJECTIVE: This research have done in order to evaluate the expression and regulation of hBD-3 mRNA in human keratinocyte cell lines. METHODS: HaCaT cell lines were used to all culture experiments. Cultured human keratinocytes were stimulated with UV irradiation or TNF-α or LPS to determine whether hBD-3 mRNA production occurred. Reverse transcription-polymerase chain reaction (RT-PCR) was per-formed to amplify hBD-3 cDNA from stimulated keratinocytes in a time dependant manner, and densitometry was used to verify the specificity of RT-PCR amplication products. RESULTS: Expression of hBD-3 was upregulated with UV irradiation, TNF-α and LPS in Ha-CaT cells compared to control CONCLUSIONS: Human keratinocytes are capable to induce hBD-3 mRNA, as well as hBD-2, in response to UV irradiation, TNF-α and LPS. suggesting that these cells could play an important role against the bacterial infection and UV light damage in human skin.

A histopathological study was performed on nevus sebaceus to observe its aging effect based on 75 cases of neuvs sebaceus those were collected during the past 10 years from three university hospitals in Seoul. The results are as follows: 1) Clinical findings The incidence was most frequent in the teenage group. The 75 cases consisted of 41 males and 34 females with a sex ratio of 1.2:1. Most of cases developed in the head and neck areas with 62.7% on the scalp and 29.3% on the face. 2) Histopathologic findings. The epidermal changes such as acanthosis(40%), papillomatosis(73%), hypergranulosis(44%) were most remarkable in the second decade and gradually decreased with aging. The apparent proliferation of sebaceous gland was observed in 73% and it was most prominent in the second decade. Apocrine glands were absent before the first decade but apparently increased after then. Proliferation of eccrine gland was not significant in all the age groups. Mild increase of immature hair follicles were noted in 49% of our cases with gradually decreasing tendency in the older age. The dermal inflammatory infiltrates were noted from the 2nd decade(28%) and thereafter gradually increased. Associated neoplasms were one apocrine adenoma, one sebaceous adenoma, two trichilemmomas and two arteriovenous hemangiomas. The majority of tumors occured in the third decade. Therefore, it is observed that neuvs sebaceous undergoes dynamic histopathologic changes according to the age of patient and later develop various secondary neoplastic changes. The pathogenesis of the nevus sebaceus is suggested to be closely related with developmental anomalies of primitive hair germ units in fetal stage.
