Most glomerular lesions are associated with qualitative and quantitative alterations of the extracellular matrix components, having relation to progressive glomerular sclerosis. We aimed to investigate the characteristic alteraltions in distribution of extracellular matrix components, such as fibronectin, laminin, collagen type III and IV in human glomerular diseases by immunohistochemical method. The materials included are 3 nephrectomy as normal control, 51 renal biopsies and I autopsy; 3 normal, 5 minimal change disease, 5 minimal change disease with minimal mesangial lgA deposit, 5 benign recurrent hematuria, 10 focal segmental glomerulosclerosis, 15 lgA nephropathy, 10 membranoproliferative glomerulonephritis, 2 diffuse mesangial sclerosis of infancy. Type IV collagen and laminin were present normally in the mesangium, GBM, TBM and interstitial vessels, and were increased at the portion of increased mesangial matrix, of sclerosis and thickened GBM in cases of lgA nephropathy, membranoproliferative glomerulonephritis, focal segmental glomrulosclerosis and diffuse mesangial sclerosis in the proportion to the glomerular damage. Type III collagen was absent in the normal glomeruli, but was detectable focally and segmentally in cases of membranoproliferative glomerulonephritis, IgA nephropathy and focal segmental glomerulosclerosis at the sclerotic portion. Fibronectin was normally detectable mainly in the mesangium, and partly and incompletely in GBM, and was increased at the portion of increased mesangial matrix, sclerosis and thickened GBM in cases of focal segmental glomerulosclerosis, membranoproliferative glomerulonephritis, IgA nephropathy and diffuse mesangial sclerosis, but was diminshed at the old slcerotic portion or global sclerosis. The expression of these antibodies in cases of minimal change disease, minimal change disease with minimal mesangial IgA deposit, benign recurrent hematuria was not different, quantitatively and qualitatively, from that of normal glomeruli. These findings suggest that progressive glomerular sclerosis was due to the increase of extraceuular matrix components such as type IV collagen, laminin, fibronectin and new appearance of type III collagen, and the expression was in proportion to the degree of sclerosis, but had no relation to the disease entity.

Hamartoma of the breast is relatively rare benign tumor, which is a well-circumscribed mass mainly composed of fibrous stroma, a(tipose tissue, ducts and acini. Muscular hamartoma of the breast is mainly composed of smooth muscle, and is extremely rare because proper smooth muscle is normaly absent in the breast except in the nipple. We describe a rare case of muscular hamartoma of the breast in a 38-year-old woman. This tumor was located in the upper outer quadrant and a 3 x 2.5 x 2 cm sized, well-demarcated but not encapsulated mass, The mass consisted mainly of irregularly arranged smooth muscle bundles in the fibrous stroma with lobular units and admixed fat cells. The origin of smooth muscle in hamartoma is not well known.

In 1908 Leiner described the peculiar skin condition among infants to which he applied the name erythroderma desquamativa. The four cardinal features of Leiners disease are generalized seborrheic dermatitis, intractable severe diarrhea, recurrent local and systemic infections usually of gram negative etiology, and marked wasting and cyst rophy. A 2-month-old female presented to our clinic with generalized seborrheic erythrodermic eruption and intractable diarrhea. She had sufferd from these symptoms since birth. Her body weight was 3.4kg (below 3rd percentile). Her scalp was covered with thick yellowish crsts. There was generalized erythroderma covered vith scales and crusts. Laboratory result; revealed gram negative sepsis and DIC. Chest X-ray showed the findings of minimal aspir ition pneumonia in the right upper lobe. She expired on the following day.

To know the correlation between glomerular and tubulointerstitial lesion and to define the characteristics of interstitial inflammatory cell in IgA nephropathy and classified according to WHO classification and graded tubulointerstitial lesion as mild, moderate and severe. Paraffin-embedded 5u sections were stained with UCHL-l, L26 and CD68 antibodies. More than 20 fields were examined in each case under the high power microscopy and the number of positive cells were counted. There was positive correlation between the severity of glomerular and that of tubulointerstitial lesion. The mostcommoninflammatory cells in the interstitiuin were UCHL-l positive cells followed by CD68 and L26 positive cells. As the WHO grade or tubulointerstitial lesion increased, the numbers of positive cells were increased in all three groups. The proportion of UCHL-1 Positive cells were increased in cases with high WHO grade whereas that of L26 positive cells incases with severe tubulointerstitial lesion Proteinuria was correlated with the degree of inflammatory cell infiltration, especially with that of L26 positive cells.

An aneurysm occurs in association with trauma, atherosclerosis, infection and congenital diseases. Among these, the traumatic arterial aneurysms developed from blunt trauma, crushing injury, perforation, and lacerations of vessels. Generally, most traumatic arterial aneurysms are false type, so called pseudoaneurysm. A pseudoaneurysm occurs by incomplete laceration of the vessel wall or partial division of the vessel. The vascular injury will make hematoma and fibrosis of neighboring tissues. After two to eight weeks post-trauma, the organized hematoma is liquefied and the fibrous tissue acts as an aneurysmal sac. We have experienced a case of dorsalis pedis artery pseudoaneurysm associated with arterial cannulation. So, we report a case of traumatic pseudoaneurysm with a review of literature.

We report a case of aggressive angiomyxoma in ischiorectal fossa of a 39-year-old women. The tumor is characterized by relatively large size(13 x 11 cm), grossly gelatinous appearance and locally infiltrative nature. Microscopically, it consists of many variable sized blood vessels and spindle or stellate cells widely separated in myxoid or collagenous stroma. Immunohistochemical stains reveal that the tumor cells are strongly positive for actin and desmin. Electron microscopic findings are that of a few cells dispersed in abundant intercellular substance and collagen bundles. These cells form irregular cytoplasmic process without basal lamina and contain endoplasmic reticulum having cistern.

Recent development in the polymerase chain reaction( PCR) technology has brought an extraordinary opportunity for the rapid detection of Mycobacterium tuberculosis in clinical specimens for the diagnosis of tuberculosis. This study was initiated to compare the PCR results with those obtained by culture on Ogawa medium. A total of 18 urine samples from patients suspected having tuberculosis were tested by PCR using the primer: P1(5'-AGC-ACG-GCG-ATT-TGG-AGT-CG-3')andP2 (5'-ATC-GTT-TTC-GGC-GGT-ATC-TG-3'). Of 5 culture positive samples, 3 showed the 320 bp DNA products in PCR and 2 were negative. Besides, 3 of 13 culture negative samples also showed positive results in PCR. In conclusion, the PCR easily detected M.tuberculosis in smear-positive samples. The PCR could detect the presence of M.tuberculosis when the samples were culture negative. Therefore, the PCR was probably more sensitive than culture. Because of the extreme sensitivity of PCR, one would expect to be able to detect organism that are present in low numbers and those that are nonviable. However, the PCR method could miss the culture proved M.tuberculosis. The PCR method looks promising for the rapid and specific laboratory diagnosis of tuberculosis.
