A 51-year-old man presented with a 2-year history of painless lump in the left hemiscrotum. Scrotal examination demonstrated a 3-cm, firm-to-hard mass attached to the left spermatic cord. Scrotal ultrasound scan revealed a heterogeneous mass separate from the left testis and epididymis. An orchidectomy was recommended to the patient; however, he declined surgery and underwent excision biopsy of...

The hepatoprotective effects of a Taiwanese crude herb, Hwang-hua-mih-tsay (Wedelia chinensis (Osbeck) Merr.), were investigated. Acute hepatitis was induced by three hepatotoxins: carbon tetrachloride and acetaminophen in mice, and D(+)-galactosamine in rats. After treatment with W. chinensis (300 mg/kg, p.o.) at 2, 6 and 10 hours, a reduction in the elevation of serum glutamate oxaloacetic tr...

An 11-year-old girl presented to our department to have a second opinion regarding a lesion involving her left mandible. She had previously undergone several radiographic exams including panoramic, helical, and cone-beam computed tomography. Radiographic examinations revealed a well-defined radiolucent region, which contained an irregular radiopaque mass of 3 cm in diameter, localized to the le...

The aim of this study was to investigate neuron-specific enolase (NSE) immunoreactivity of the different brain regions after pentylenetetrazol (PTZ)- induced epileptic seizures in rats. Light microscopic examinations provided evidences for changes of neuronal activity after single and repeated seizures. The number of NSE (+) cells was well correlated with Nissl staining. The results suggest tha...

Cardiac and pancreatic lesions were observed in guinea pigs infected with 2 variants (B and D) of encephalomyocarditis (EMC) virus. Cardiac changes were characterized by focal myocardial necrosis and subsequent replacement by immature granulation tissue, and the pancreatic ones by vacuolar degeneration of acinar cells. In the electron microscopic examinations, the affected cardiomyocytes showed...

The aim of the experimental research was to assess the impact of a high damage to brachial plexus elements on the condition of neurons of spinal cord anterior horns. The research was conducted on 12 rabbits, in which the ventral branches of spinal nerves C5-Th1 were severed. During dissections carried out 7, 30, 60, 180 days after the operation the cervicothoracic segment of the spinal cord was...

UNLABELLED Primary sinonasal clear cell carcinoma is a rare neoplasm classified under malignant epithelial tumours of salivary gland - type carcinomas under World Health Organization (WHO) classification. We report a case which occurred on a 69 year old gentleman presented with epistaxis and nasal endoscopy examination showed tumour arising from the right ethmoid cells. Endoscopic excision of t...

Species delimitation of Psoroptes spp. and identity of the parasite in water buffaloes remain poorly defined. In this study, Psoroptes infestation on three water buffalo farms in Egypt was examined based on morphometric characteristics, especially the opisthosomal setae of adult male mites. Clinical investigations showed that 28% (196/700) of the sampled animals had mange infestation. Microscop...

background: morphological examinations of urinary erythrocytes can be of diagnostic value in initial evaluation of hematuria. dysmorphic urinary red blood cells are known to indicate a glomerular origin of bleeding. we examined the clinical usefulness of this test in a population complained of hematuria by use of three different methods: light microscopy, phase contrast microscopy, and wright s...

Fragments of the liver were collected and processed histologically, from six swine four months age, having positive coproculture tests for Ascaris suum. On microscopic examinations were observed larval migration routes. A small number of them did not present reparatory processes, which showed that they were relatively recent. Most of the areas affected presented reparatory processes in differen...
