Meningeal sarcoma is rare and its clinical course tends to be short. It is a malignant neoplasm arising from connective tissue elements present in meninges. We have experienced a case of 4 years old female patient with headache, palpable mass on left parieto-occipital area. The operation revealed entirely extradurally located, firm, vascular tumor and almost total excision was done. It was histopathologically diagnosed meningeal sarcoma but indisinguishable from malignant menigioma.

The relationship between clinical features of brain dysfunction after severe head injury and prognosis has been analyzed for 80 patients among 2,053 cases of craniocerebral injury. 68 patients died within 6 months and 1 patient after 6 months. 33 patients had a Glasgow coma score of 3-4 and showed poor prognosis. 52 patients with unreactive pupil and 51 patients with impaired or absent eye movements showed poor prognosis. The most common types of lesion causing poor prognosis were subdural hematoma(32.6%). There was no difference in prognosis whether operation was done or not within 6 months. But 12 patients had been alived longer than 6 months, among them 9 patients were operated and 3 patients were not. Patient age, depth of coma, pupil reaction, eye movements proved to be the most reliable predictors and main lesion, operation probable predictors. The degree of brain dysfunction changed markedly soon after injury, and more reliable prediction of prognosis resulted when assessment was based on the level of functioning recorded in each early epoch. Individual predictions of prognosis, provided a powerful tool for assessing the relative efficacy of alternative treatments.

For labor saving control of weeds in paddy fields, it is better to apply 0 DAT (day after transplantation) herbicide. Fenquinotrione·pyraclonil·pyrazosulfuron-ethyl granule is a newly developed herbicide that has a wide application range and is safe for rice. In particular, this herbicide can effectively control Monochoria vaginalis var. plantaginea, Scirpus juncoides etc., which are resistant to sulfonylurea-based herbicides. Since the 0 DAT herbicides are highly likely to cause damage to the rice, it is recommended to apply it after checking the condition of rice development, harrowing etc. 논에 발생한 잡초를 생력적으로 방제하기 위해서는 이앙동시처리제를 살포하는 것이 좋다. 펜퀴노트리온·피라클로닐·피라조설퓨론-에틸 입제는 새롭게 개발되어 적용범위가 넓으면서 벼에 안전한 이앙동시처리제이다. 특히 이 제초제는 설포닐우레아계 제초제에 저항성을 보이는 물달개비, 올챙이고랭이 등을 효과적으로 방제할 수 있다. 이앙동시처리제는 벼에 약해가 발생될 가능성이 높기 때문에 벼 발육상태, 써레질 상태 등을 잘 확인한 후 살포하는 것이 좋다.

Lasers have been used safely to aid in the resection of highly vascular tumors or arteriovenous malformation. As far as blood vessel coagulation, arteries up to 2 MM in diameter and veins up to 3 nig in diameter can be reliably sealed with the Nd-YAG laser, and lesser size of vessels can be coagulated with the CO₂ laser. Another advantage of laser is to be a useful tool for small vessel repair or anastomosis without microsuture technique. The aim of this experiment was to investigate intensity and duration of exposure with the CO₂ laser for vessel coagulation and repair. 36 rats weighing 200 to 250 gm, were used in this study. For vessel coagulation of extracranial arteries and veins, power density between 10 and 50 watts/㎠ (W) was applied with handpiece, and for vessel repair or anasomosis 2 W was applied with micromanipulator. The results obtained were as follows: 1) The artery was perforated immediately over 10 W with 0.5 seconds of exposure of smaller focal beam. 2) The artery was constricted in its diameter in defocused beam with 30-40 W, and perforated with 50 W. 3) The lower limit of venous coagulation was 15 W, 0.5 sec. of exposure and 2㎜ of focal beam diameter. 4) The lower limit of arterial coagulation was 10 W, 5 sec. of exposure, 4㎜ of focal beam diameter, and exposure time was reduced to 3 sec. at 20 W. 5) The repair or anastomosis of artery was accomplished with 2 W, 0.05 sec. of exposure of 0.2 ㎜ of focused beam by 6 times of delivery, and the delivery times could be successfully reduced to half under the overlying thin blood clot film on the anastomosis site of the artery. 6) In the histological examination, the entire layer of coagulated vessel wall on the laser delivered side disclosed marked constriction and destruction. On the anastomosis site, re-endothelialization began from 3 days, and completed by 2 weeks after operation.

After von Rokitansky's description in 1884 of a calcified chronic subdural hematoma, the number of such lesions has reached so far a total of 108. The majority of patients reported have been children and young adults. On review of the literature, by elderly patients reported over the age of sixty five years are only 5, so far as we know. A 68-year-old Korean male with a calcified chronic subdural hematoma is reported. He was admitted to our department because of a status epilepticus. During Korean war (1950), about 37 years before admission, he had been suffered from a blunt head injury, but mistreated then, and afterwards he had had several episodes of convulsion. Neurological examination on admission revealed only a drowsy consciousness and mild papilledema on the left. Plain skull X-ray films and brain CT scan demonstrated a left sided biconvex type of intracranial calcification. A left frentoparietal craniotomy was performed. After opening the dura mater, the thickened outer membrane, the subdural hematoma and the thin bone like plate were removed thoroughly. Content of the subdural hematoma was brown muddy substance. In the eight months following the operation, the generalized seizure did not appear. Postoperative CT scan demonstrated complete re-expansion of the brain parenchyme.

A retrospective analysis of 351 linear skull fractures, during the period of January 1, 1992 to December 31, 1993, reveals the following : 1) Motor-Vehicle-related accidents were responsible for most of the injuries(56%), in which pedestrians(47%) were the primary victims. 2) In 172 cases(49%), the Glasgow Coma Scale(GCS) ranged from 13 to 15. Patients with parietal fractures usually rated on a lower scale than those with fractures on other sites. 3) Occipital fractures were most common(23%), which was followed by parietal(19%), temporal(15%), frontal(15%), and multiple fractures(8%). Occipital fractures were frequently due to a pedestrian T.A. or a fall from high elevation while temporal or parietal fractures were frequently due to bicycle and motorcycle accidents. 4) The incidence of associated intracranial lesions was 70%. Patients with occipital fractures had a lower percentage of associated intracranial lesions than those with parietal fractures. Coup injuries were found in 175 cases and contre coup injuries in 106 cases. In many cases, frontal, parietal and temporal fractures were found to be coup injuries whereas with occipital fractures, contre coup injuries. 5) Sixty-one percents of the patients were assessed in Glasgow Outcome Scale(GOS) gradeⅠ.
