Résumé
Sparganosis is an infection with a parasitic tapeworm larva that occurs by eating infected foods or drinking contaminated water. The larvae can migrate to a tissue or muscle in the chest, abdominal wall, extremities, eyes, brain, urinary tract, pleura, pericardium, spinal canal, or scrotum. Herein, we report a 5-month old infant with scrotal sparganosis who was initially suspected to have a scrotal inflammatory mass with a history of applying raw frog meat into the umbilicus. Preoperative ultrasound examinations and computed tomography (CT) scanning misdiagnosed the mass as a scrotal teratoma. The scrotal mass was surgically removed, and the histopathology proved it to be scrotal sparganosis. This case displays the youngest patient ever reported with scrotal sparganosis, and the first description of CT characteristics of scrotal sparganosis. A detailed medical history is necessary for patients with scrotal masses suspected of sparganosis. In addition, ultrasound and CT examinations are helpful to rule out other causes of a scrotal mass.

<p><b>OBJECTIVE</b>To study the effect of matrine (MAT) on the proliferation of human ovary malignant teratoma cell line PA-1 in vitro.</p><p><b>METHODS</b>PA-1 cells allocated in different groups were treated with different concentrations (0.25 mg/mL, 0.5 mg/mL and 1.0 mg/mL) of MAT. The inhibitory effect of MAT and its dose- and time-effect relationship were detected with MTT; the apoptosis rate and cell cycle were evaluated by flow cytometry; and the changes of bcl-2/bax mRNA expression in cells were measured using semi-quantitative RT-PCR.</p><p><b>RESULTS</b>After being exposed to MAT, the PA-1 cell proliferation was decreased in a concentration- and time-dependent manner; cell apoptosis rate raised as the increasing concentration of MAT and acting time; cells retarded at G1 phase in the cell cycle dose-dependently; and the bcl-2/bax mRNA expression in cells dawn-regulated significantly.</p><p><b>CONCLUSION</b>MAT can dose- and time-dependently inhibit the proliferation of PA-1 cell by reducing bcl-2/bax mRNA ratio to produce a G1 phase arresting in cell cycle.</p>

Objective To investigate the effects of high spermatic vessel dissection on testicular morphological alteration of SD rats in prepuberty,puberty and sexual maturity phases.Methods Thirty-day-old SD rats were divided into 2 groups underwent sham operation and left high spermatic vessel dissection as a simulation of Palomo′s maneuver.Detailed morphological investigations were made at 3 different postoperative intervals among the 3rd day,30th day and 56th day.Results High spermatic vessel dissection in prepubertal rats induced acute testicular ischemia in the operated testes on the 3rd day.Most of the operated testes on the 30th day showed testicular atrophy.And all the operated testes showed testicular atrophy and sperm disappearance in epididymis on the 56th day.Conclusion High dissection of spermatic vessel in prepubertal rats induced testicular ischemia in prepuberty and testicular growth failure in puberty,testicular atrophy completely and sperm production losing in sexual maturity phase.
