The author experienced a case of $Henoch-Sch\"{o}nlein$ purpura with epididymitis in a 6-year-old boy who was admitted to our hospital due to left scrotal pain and the relapse of purpura on lower extremities for 3 days. Scrotal ultrasonography on admission revealed homogenously enlarged left epididymal head and small amount of fluid collection in left tunical space. The size of left epididymal head decreased gradually with no more evidence of fluid collection on day 7 and recovered completely on day 21. The author reports a case of $Henoch-Sch\"{o}nlein$ purpura with epididymitis with brief review of related literatures.

Excretory urography is a procedure where opacification of the kidneys, renal pelvic diverticula, ureters, and urinary bladder is a result of renal excretion of an intravenously administered iodinated contrast agent providing both anatomical and functional assessment. And ultrasonography is a non-invasive modality to evaluate the important anatomic information concerning the size, shape, and internal architecture of kidney even in the presence of impaired renal function or abdominal fluid. We describe four dogs with urological signs diagnosed with excretory urography and ultrasonography. Parients showed a variety of clinical signs including vomiting, hematuria, anorexia, abdominal pain, and abdominal distension. The hydronephrosis was diagnosed in case 1, 2, and 3 that had pelvic dilation, dilation of pelvic recesses, ureteral dilation. In case 3, proximal ureteral rupture was diagnosed with evidence of contrast media leakage was seen in proximal ureter. In case 4, the rupture of urinary bladder was diagnosed with leakage of contrast media through its ventral portion.

We describe a case of fine needle aspiration cytology of renal angiomyolipoma which was not associated with the clinical complex of tuberous sclerosis and was incidentally found. It was a solitary lesion and the clinical impression before needle aspiration was renal ceil carcinoma. The aspirated specimen showed mature fat cells, clusters of renal tubular epithelial cells and sheets of pleomorphic smooth muscle cells with fibrillary cytoplasm. The nuclei of smooth muscle celis varied in size and shape. Since the treatment of renal angiomyolipoma differs from that of renal ceil carcinoma, the preoperative cytological diagnosis is of great value.

Since April, 1957, 200 White Leghorn and 100 Newhampshire had been brought to the poultry farm of our college from Songwhan National Breeding Station. The looses due to avian tuberculosis were 67 chickens by June, 1959. Thirteen of them were examined histopathologically. Grayish white tuberculous nodules varying in size were recognized in the liver, spleen, bone marrow, and intestine of all affected birds. The heart rind testis were involved in each case, and pulmonary tuberculosis which, unlike in mammals, was kown to be rarely encountered in birds was observed in two cases. One case showed amyloid like degeneration in hepatic cell cords of the liver, glomerular tufts and collecting ducts of the kidney. Lesions in the spleen presented typical Sago spleen. Sections from the liver, spleen, intestine, and lungs were stained by Ziel-Neelsen stain. Acid Fast stained bacilli were found embeded in the cytoplasm of epithlioid cells and foreign-body giant cells.

An incidentaloma is a tumor found incidentally without clinical symptoms or suspicion; the lesion may be adrenal, pituitary, or thyroidal. We report the case of an asymptomatic individual with preoperatively undiagnosed pheochromocytoma (size: 4.86 cm) that was revealed using elective nonadrenal surgical procedures. The patient demonstrated peri- and post-operative hypertensive crisis and tachycardia. Three days after the dramatic onset of symptoms, the patient expired due to pulmonary edema, multiple organ failure, and terminal sepsis, despite administration of extracorporeal membrane oxygenation-assisted cardiopulmonary resuscitation. A left medial kidney mass obtained at autopsy confirmed pheochromocytoma.

Renal cell carcinoma (RCC) is common primary tumor of kidney. In the past, it had been considered a difficult tumor to manage since the detection was usually delayed until paraneoplastic syndrome and/or distant metastasis appeared due to its slow progression. However, the recent popularization of ultrasound and computed tomography has made RCC one of the easily curable cancers. Eighty percent are found early, mostly with tumor size less than 5 cm. Five-year survival rate after successful nephrectomy is exceeded 80-90 percent. Curative nephrectomy can be tried in stage 1 and 2, and some cases of stage 3. In these cases, return to flight can be considered after 6 to 12 months' observation. It should be monitored any occurrence of cancer recurrence, need for systemic treatment, metastasis, and paraneoplastic syndrome, etc. If any signs of recurrence are found or new treatment needs to be initiated, the flight should be suspended. If there is no recurrence for more than 5 to 10 years, the patient doesn't have to be followed anymore.

The histological changes in the Ussurian bullhead, Leiocassis ussuriensis, and the Korean bullhead, Pseudobagrus fulvidraco, were observed during the early period of growth. The retinas size of both species increased in the 9 days post-hatching (DPH) (p<0.05). In the just-hatched Ussurian bullhead, the retina already consisted of six layers: the epithelial layer, ganglion cell layer, inner nuclear layer, inner plexiform layer, outer limiting membrane layer, and rod and cone layer. The Korean bullhead had the same components. At 50 DPH, the thickness of the retina was $538.0{\pm}7.19{\mu}m$ in the Ussurian bullhead and $558.9{\pm}9.44{\mu}m$ in the Korean bullhead. The relative thickness of each layer of the retina did not differ significantly in the two species. Although the growth of the Korean bullhead's retina was faster, the relative thickness of each layer in the retina did not change during early development. After hatching, some parts of the tissue gradually became denser. Immediately after hatching, the kidney and midgut epithelium of the Ussurian bullhead and Korean bullhead were already formed and grew gradually thereafter. From 0 DPH to 30 DPH, the nuclear height in the midgut epithelium did not differ significantly between the two species, but at 50 DPH, it was $11.4{\pm}2.45{\mu}m$ in the Korean bullhead and $9.9{\pm}2.13{\mu}m$ in the Ussurian bullhead. During the experimental period, the major axes, minor axes, surface areas, and volumes of the proximal tubule cells in the kidney did not differ significantly between the two species. Thus, the early histological development of the Ussurian bullhead is similar to that of the Korean bullhead.

Present study aims to investigate the effect of muddy water on various tissues and plasma proteins of Hemiculter eigenmanni in Imha reservoir. The gills in muddy water were shown to have clubbing in secondary lamellae and edema in primary lamellae, respectively. The size of glomerula in kidney was smaller than that of control. Scanning electron micrographs of gills revealed muddy debris and parasites attached between primary and secondary lamellae, suggesting that muddy water possibly involves to decrease in respiratory rate. By using SDS-PAGE, plasma protein bands displayed both quantitative and qualitative changes and ferritin activities were shown more stronger and Fe-3 ferritin band appeared to be specific to plasma of muddy water.

Purpose: The aim of this study was to establish a simple formula to predict renal length in children using a Technesium-99m dimercaptosuccinic acid (DMSA) scan data, and to compare it with the formula derived from ultrasonography, which is widely accepted. Methods: Children who underwent a DMSA scan and ultrasonography were reviewed retrospectively, and those who had anatomical urinary tract abnormalities or urinary tract infections were excluded. Results: A total of 230 children (84 males and 146 females; age, 1 month to 16 years; mean age, $16.8{\pm}27.4$ months). Mean renal length measured by DMSA scan was longer than that by ultrasonography ($6.38{\pm}1.16$ vs. $6.02{\pm}1.14cm$; P < 0.001). Renal length was correlated with age, weight, height, and body surface area on the DMSA scan and ultrasonography, and showed the strongest positive correlation with height. The following formulae were established to predict renal length: mean renal length (cm) = 5.433 ${\times}$ height (m) + 2.330 (R2, 0.833) using the DMSA scan data, and mean renal length (cm) = 5.367 ${\times}$ height (m) + 2.027 (R2, 0.853) using ultrasonography data. Conclusion: We propose a simple height-based formula to predict renal length in children using a DMSA scan data, and validate it by comparing with ultrasonography formula.

Background: This study concerns clinical characteristics and survival of renal cell carcinoma (RCC) patients in University Malaya Medical Centre (UMMC), as well as the prognostic significance of presenting symptoms. Materials and Methods: The clinical characteristics, presenting symptoms and survival of RCC patients (n=151) treated at UMMC from 2003-2012 were analysed. Symptoms evaluated were macrohaematuria, flank pain, palpable abdominal mass, fever, lethargy, loss of weight, anaemia, elevated ALP, hypoalbuminemia and thrombocytosis. Univariate and multivariate Cox regression analyses were performed to determine the prognostic significance of these presenting symptoms. Kaplan Meier and log rank tests were employed for survival analysis. Results: The 2002 TNM staging was a prognostic factor (p<0.001) but Fuhrman grading was not significantly correlated with survival (p=0.088). At presentation, 76.8% of the patients were symptomatic. Generally, symptomatic tumours had a worse survival prognosis compared to asymptomatic cases (p=0.009; HR 4.74). All symptoms significantly affect disease specific survival except frank haematuria and loin pain on univariate Cox regression analysis. On multivariate analysis adjusted for stage, only clinically palpable abdominal mass remained statistically significant (p=0.027). The mean tumour size of palpable abdominal masses, $9.5{\pm}4.3cm$, was larger than non palpable masses, $5.3{\pm}2.7cm$ (p<0.001). Conclusions: This is the first report which includes survival information of RCC patients from Malaysia. Here the TNM stage and a palpable abdominal mass were independent predictors for survival. Further investigations using a multicentre cohort to analyse mortality and survival rates may aid in improving management of these patients.
