Herpes zoster is an infection by the varicella zoster virus in a partly immune compromised person such as old age, cancer, immune deficiency disease. When either the upper lumbar or sacral segments are involved, serious urinary retention caused by central spread of herpes zoster from dorsal root ganglion can occur. The urinary disturbance appears to have been due to motor dysfunction of detrusor muscle, trigone muscle, and internal sphincter. We experienced two cases of zoster affecting different segments of the spinal cord and resulting in urinary retention.

The authors report a case of 42-year-old woman with an intraventricular tumor in the trigone of the left lateral ventricle. The first operation achieved a microscopically complete resection. The tumor was histologically atypical meningioma. After 26 months, there were recurrences of intraventricular meningioma. Complete resection of the tumor and adjuvant radiation therapy were performed, and the histological diagnosis was malignant meningioma. Sixteen months after the second operation, spinal metastasis in cervicolumbar lesion was diagnosed and a subtotal removal of cervical intradural extramedullary mass was performed. We describe an unusual case of intraventricular malignant meningioma with cerebrospinal fluid-disseminated spinal metastases with review of the clinical courses of previous reports.

The authors report a case of atypical meningioma in the fourth ventricle. Intraventricular meningioma is not uncommon intracranial neoplasm, especially that in the trigone of lateral ventricle, however, those in the third and fourth ventricle are very rare. There are only two cases of atypical meningiomas in the fourth ventricle among 29 cases of fourth ventricular meningiomas reported 17 literature. The clinical features, findings of magnetic resonance image and operation of our case, and review of literature are presented.

Choroid plexus carcinomas are extremely rare in adults. They can behave aggressively and their optimal management is uncertain. A 35-year-old woman was admitted with an episode of loss of consciousness. Magnetic resonance imaging showed a homogeneously enhancing mass in the trigone of the right lateral ventricle. Detailed examinations found no evidence of an extraneural primary focus. She underwent total removal of the tumor. Pathological diagnosis was confirmed as a choroid plexus carcinoma. She is doing well eight months after surgery.

Salivary gland tumors take possession of almost 5% in head and neck malignancies. Among these, mucoepidermoid carcinoma(MEC) is most common malignany in major salivary glands(12-29%) and the parotid gland is most predilection site. Intra-oral MEC has a tendency to various locations, and the predilection sites are palate, cheek, mandible, lip and tongue in order of frequency. A few cases of MEC are occurred in with retromolar trigone, oropharynx, and ectopic salivary gland. Recently, we experienced a-65-year old woman with retromolar trigonal mass, and she was finally diagnosed as MEC. We report it with review of literature.

We report a case of trigonal cavernous malformation (CM) radiologically mimicking meningioma. The computed tomographic (CT) head angiography and magnetic resonance imaging (MRI) showed a partially calcified lesion with slight contrast enhancement located in the area of the left atrium of lateral ventricle. The lesion was completely removed using microsurgery with a parieto-occipital transcortical approach. The resected mass was histologically confirmed as CM. CM should be considered as differential diagnosis in case of the atrial mass lesion due to lack of hemosiderin ring characteristically seen other seated CM.

A 12-year-old dog was evaluated for depression and anorexia. The results of complete blood count and serum biochemistry were normal. Survey radiographs revealed markedly enlarged right kidney and abdominal ultrasound showed a renomegaly and hydronephrosis filled with mixed echogenic fluid. Primary renal tumor was suspected in this dog. Nephroureterectomy of the right kidney was performed, and no regional metastases have been identified. Transitional cell carcinoma (TCC) arising from renal pelvis accompanied hydronephrosis of the right kidney was diagnosed on histology. TCC usually affects trigone of the bladder, and renal origin of TCC is a very rare finding in dogs. This is the first case report to present the clinical features, diagnostic imaging findings and histopathological characteristics of a dog with TCC originating from the renal pelvis in Korea.

Study purposes were to evaluate ultrasonographic characteristics of transitional cell carcinoma (TCC) and quantitate bladder tumor size in dogs. Heterogeneous mass, wall involvement, and broad-based attachment were significantly associated with TCC, but not prominently the trigone region. Mass size evaluation revealed a significant correlation between progressive disease (PD) in TCC patients with piroxicam therapy. Largest diameter of target lesion/body weight (cm/kg) ratio showed a high mean value in PD. A value > 0.3 was associated with PD with 83% sensitivity and 66% specificity. The results suggest that ultrasonography can provide evidence for diagnosing and predicting a prognosis for TCC.

A clinical study of selected patients with intraoral squamous cell carcinoma which were managed in the Department of Oral Oncology of Korea Cancer Center Hospital from January 1982 to August 1989 was done. And following results were obtained. 1. Males were involved more than females by intraoral squamous cell carcinoma in a ratio of 4:1. and most of the cases occurred in the 7th and 6th decades (69%). 79% of total patients and 92.5% of males were. 2. The mean duration of symptomatic period was 5.9 months. 3. The common symptoms were swelling (63%), pain (40%), ulceration (33%), and trismus (23%) 4. In the histologic findings, well differentiation comprised 58.0%. 5. The primary sites were the upper alveolar mucosa (32%), the floor of the mouth (21%), the lower alveolar mucosa (19%), tongue (14%), retromolar trigone (8%), palate (7%) and buccal mucosa (3%). 6. According to TNM system, Stage I, Stage II, Stage III, and Stage IV comprised 4%, 15%, 32%, and 49% respectively. 7. In the management of intraoral squamous cell carcinoma, surgeries were done in the 32 cases, 23 cases of which were managed by radiation therapy or chemotherapy concurrently. And radiation therapy alone was received in 35 cases. 8. Overall 3 and 5-year survival rates without regarding to stage were 27.6% and 21.4%. 9. 3-year survival rate of female patients was 47.2% and that of male patients was 22.6%. 10. 5-year survival rate was 53.9% for "early" cancer (stage I and II) and 15.6% for "advanced"cancer (stage III and IV). Survival rate of patients in the early stages of cancer appeared to be higher than that of patients with stage III and IV(p<0.05).

Etomidoline ($Nonspa^{\circledR}$), which is chemically related to tertiary amine, is new synthetic antispasmodic agent with analgesic action. Antispasmodic effect of this agent is stronger than hyoscine butylbromide ($Buscopan^{\circledR}$), quaternary amine, and the absorption from intestine is also much higher. This study was undertaken to determine the effect of etomidoline on duodenal motility and other smooth muscles of rabbit. Strips of various isolated smooth muscle, 2 cm long from adult rabbits weighting about 2 kg, were suspended in a muscle chamber containing Tyrode's solution, which was bubbled with oxygen gas, and the temperature of the solution was kept constant at $38^{\circ}C$. After being washed with fresh solution several times the strips of smooth muscle attained constant motility and tonus. Etomidoline and other drugs were added in various concentrations to the chamber. Contractility of the strips was measured by using polygraph (Grass, model 7). The results are as follows: 1) In isolated rabbit atrium etomidoline produces a slight depression of contractility and the rate is also decreased. 2) On the other hand, etomidoline relaxed isolated strips of stomach, duodenal, and detrusor of rabbit. This relaxing effect of etomidoline on isolated duodenal strip of rabbit was not blocked by ${\alpha}$-adrenergic blocking agent, phenoxybenzamine, but by ${\beta}$-adrenergic blocking agent, propranolol. 3) Etomidoline did not exert any effect on isolated aorta, gall bladder, and trigone of rabbit. From the above results, it may be concluded that the relaxing effect of etomidoline on duodenal strip is related ${\beta}$-adrenergic receptor.
