Recently, the 5-year survival rate of rhabdomyosarcoma has been greatly increased by combining therapy with radical surgery, radiation and chemotherapy. But it still has poor prognosis and there are few case reports of rhabdomyosarcoma of head and neck with long term survival rate. Here, we treated a rhabdomyosarcoma patient with radical surgery, radiation and chemotherpy. The patient visited our hospital in 1990 with a complaint of left facial protruding mass, diplopia and exopthalmos. She was diagnosed as rhabdomyosarcoma involving maxillary sinus and orbit. In september 1990, she received left total maxillectomy and eyeball exentration. After the surgery, we applied a 5000 cGy neutron therapy, 2000 cGy external radiation and 9 cycle pulse, along with VAC chemotherapy. She remains free of disease as of her last follow-up in February 1998.

We investigated the postictal EEG and semiology in temporal lobe epilepsy in order to evaluate their possible clinical utility. Fifty four well lateralized seizures in 10 patients, recorded during presurgical evaluation, were analysed in regard to the frequency, pattern and location of the EEG activity (42 seizures with scalp-sphenoidal electrodes, 27 seizures with intracranial electrodes). Postictal EEG changes were very heterogenous, at best categorized to several patterns: (1) theta+delta slowing (2) attenuation (3) spike activation, among them theta+delta slowing was mosts frequently encountered. The lateralizing value of the earliest pattern was 59.3% using intracranial electrodes but only 23.3% using scalp-sphenoidal electrodes. Postictal semiology also showed a variety of behavioral manifestation such as confusion(81.5%), lip smacking(40.7%), hand automatism (18.5%). Lip smacking was more often seen following the left temporal seizure (16 out of 22, p<.05). Behavioral distinction between ictal and postictal semiology was not possible. Postictal EEG and semiology appears to be consisting of heterogenous mechanisms and wide spectrum. We feel that the clinical utility is limited.

The purpose of this study was to examine the ultrastructural characteristic of the normal pylorus mucosa, and their structural changes induced by the ligation of common bile duct of the male rabbits weighing about 1.5 kg each. Experiment animals were divided into normal, sham operation, and experimental groups. Common bile duct ligation was performed under ether anesthesia and anjmals were sacrificed on the 1st, 3rd, 5th, 7th and 14th day after operation. The mucosal specimen of the pylorus, were fixed and embedded with common method. The sections were cut on a LKB-V ultratome, and observed under a JEM 100CX II electron microscope. The results were as follow : 1. In the early stages (1st, 3rd, 5th day groups) following the ligation, surface mucous cells have the various electron densities and shape of the mucous granules. In the late stages (7th, 14th day groups) following the ligation, many surface mucose cells containing numerous electron dense mucous granules are seen. 2. In the early stage of the ligation of bile duct, secretory function of EC cells was depressed, but in the later stage, the cells showed recovered secretory activity. 3. Secretory function of D cells was depressed on the early groups after the ligation of common bile duct, but they showed recovered secretory activity from the late groups after the ligation of the common bile duct. 4. Secretory function of G cells was activated on the early groups after the ligation of common bile duct, but they showed depressed secretory activity from the late groups after the ligation of the common bile duct. Considering the above findings, common bile duct ligation probably causes the dysfunction of the pyloric surface mucous cells that results in delayed mucous formation and secretion, and recovered mucous secretory function on the late stages. EC cells and G cells, depressed the secretory activities on the early stages and recovered on the late stages of the ligation of common bile duct. But D cells in the pyloric mucosa was activated on the early groups after the ligation of common bile duct ligation, but they was depressed secretory activities on the late groups.
