Subcutaneous fat necrosis of the newborn is an uncommon disorder which is characterized by multiple erythematous subcutaneous nodules and plaques appearing in the first week to a month of life. The chief precipitating factors presumably concerned in this disease are obstetric trauma, anoxia and cold exposure. We observed a case of subcutaneous fat necrosis of the newborn in which intrauterine asphyxia and preeclampsia had occured.

The organization of the ribosomal genes is unique in Borrelia burgdorferi in that the rrl (23S) and rrf (SS) genes are duplicated in tandem. Twelve Korean Borrelia isolates were classified by the method of rRNA gene restriction fragment length polymorphism (RFLP) and Southern hybridization. One of the isolates, KW-3, as well as the representative of ribotype group IV Ip89 appeared to have evolved within B. garinii. The size of the restriction bands of the 11 isolates showed different patterns from the USA and European isolates. The result by RFLP of rrf-rrl intergenic spacer region amplified by PCR showed a good correlation with that of Southern hybridization of rRNA gene. Therefore, the eleven Korean isolates could be classified as members of a new Borrelia group.

We report a rare case of a patient with meningeal solitary fibrous tumor. A 60-year-old woman presented with right leg monoparesis. Brain magnetic resonance imaging demonstrates a well enhancing huge mass, located in left parietal lobe. Cerebral angiography demonstrating increased vascularity in area of the tumor, which had feeder vessels extending from the internal carotid artery and external carotid artery. A presumptive diagnosis of meningioma or hemangiopericytoma was considered. At surgery, the consistency was firm and had destroyed the dura and skull. A gross total resection was performed. Immunohistochemically, tumor was strongly, and widely, positive for CD34 and vimentin. There was no staining for epithelial membrane antigen(EMA), S-100 protein, cytokeratin, and glial fibrillary acidic protein (GFAP). Differential diagnosis of intracranial solitary fibrous tumor includes fibroblastic meningioma, meningeal hemangiopericytoma, neurofibroma, and schwannoma.

The adult worm and plerocercoid larva(sparganum) of Diphyllobothrium mansoni and Moniezia expansa employed in this experiment. The adult worms were divided into three portions, i.e. immature, mature and gravid proglottids, and each proglottids were incubated in 50 cc or 250 cc volume of special incubation flasks with incubation medium consisting of 10 cc of 25 cc of Krebs-Ringer phosphate buffer (pH 7.4). The incubation medium was added C(14)-acetate and non-radioactive carrier Na-acetate so as to contain acetate concentration of 50 mg per cent. The worms were allowed to incubate for 5 hours in the Dubnoff metabolic shaking incubator at 38 C. After incubation period, the lactate and pyruvate appearance rate, total CO(2) production tate, the turnover rates were employed as pervious report(Seo et al., 1965). The quantitative analysis of C(14)-acetate utilized by the adult worm and plerocercoid larva of D. mansoni and M. expansa were compared and discussed in this report. According to these data of the experiment, it is impressed that the fatty acid such as acetate may play a role of major part of their metabolism in the adult worm and plerocercoid larva of D. mansoni , whereas minor part of acetate participated in the metabolism by M. expansa.

Twenty-eight cases of initial psoriasis were studied with histochemical methods in an attempt to obtain changes of acid mucopolysaccharides and mast cells. Early psoriatic lesions (pin head sized) and clinically uninvolved skin at distances of 2-4cm from the psoriatic lesions were excised respectively. The results are as follows; 1. Dermal changes were more prominent than the epidermal changes in almost all specimens in early psoriatic lesions. The main features of the dermal changes were perivascular inflammatory infiltrate which were consisted mainly of lymphoid cells. 2. Inflammatory infiltrate in the region of epidermal a.lteration and papillary edema is par ticulary striking. R. Among the 26 cases, the amount of acid mucopalysaccharides of initial lesion was lesser in 14 cases, greater in 4 cases and same in 8 cases as compared with clinically normal skin. 4. The number of mast cells of initial psoriatic lesion as compared with clinically normal skin was increased(p<0. 01).

The adult trematodes, Fasciola hepatica, Eurytrema pancreaticum and Paramphistomum cervi, employed in this experiment were obtained from the cattle slaughtered at the local abbatoir. The worms selected and washed several times in normal sterilized saline solution. Each about ten of intact F. hepatica, fourty of E. pancreaticum, and twenty of P. cervi were incubated in 50 cc volume of special incubation flasks with incubation medium consisting of 10 cc. of Krebs-Ringer phosphate buffer(pH 7.4) The incubation medium was added C(14)-1-acetate and non-radioactive carrier Na-acetate so as to contain acetate concentration of 50 mg per cent . The worms were allowed to incubate for 5 hours in the Dubnoff metabolic shaking incubator at 38 C. After incubation period, respiratory CO(2) samples from central well of incubation flask were analysed for total CO(2) production rate and their specific activity of respiratory CO(2). The lactate and pyruvate appearance rates were determined by analyzing the lactate and pyruvate concentration in a medium after incubation. The glycogen samples isolated from worms were analyzed for the tissue concentration and their radioactivities in order to determine the turnover rate of glycogen pool. Radioactivities of these series of experiments were counted by an endwindow Geiger-Muller counter as an infinitely thin samples. The quantitative analysis of C(14)-acetate utilized by F. hepatica, E. pancreaticum and P. cervi were compared and discussed in this report. According to these data of the experiment, it is suggested that the fatty acid such as acetate may play a part of their oxidative process into the respiratory CO2 and the synthetic process into glycogen in the above species of trematodes.

Storch is credited as being the first to describe in 1899 what we call "ependymoma" today. And ependymomas were first set apart as a single group by Bailey in 1924. The literature up to the present contains numerous reports of tumors classified as "ependymoma". From 1 to 6 percent of all intracranial tumors are ependymomas. As the above, the tumors are very rare. The incidence is higher in those with large proportion of young patients and average age is approximately 20 years. About 40 percent of intracranial ependymomas are supratentorial and the remainders are infratentorial. We experienced a case of 4th ventricular ependymoma with subarachnoid hemorrhage. A 23 year old female was admitted to the hospital because of severe headache and frequent vomiting, who had been intermittently suffered from the headache for 8 months prior to admission. On admission, the neurologic examinations revealed irritable mentality, vomiting and papilledema, and xanthochromic CSF was identified on lumbar puncture. X-ray films of skull series showed evidence of increased ICP. A mass lesion was suspected in the posterior fossa on vertebral angiogram and brain C-T films revealed a mass lesion in the midline of the posterior fossa, slightly enhanced on contrast study and associated with hydrocephalus. Following Torkildsen's shunting procedure suboccipital craniectomy was performed, and we removed the tumor mass incompletely within the 4th ventricle. The pathologically microscopic finding was papillary ependymoma, grade II. Total neuraxis irradiation was applied for 6 weeks. The post-operative course was satisfactory.

Using Mercox CL-2B, intravascular casting was performed follwoing intracameral injection with 2.0microgram/microliter of Endothelin-1(ET-1) in the rabbit eye. One hour after intracameral injection with ET-1 caused severe focal andsegmental constriction of major arterial circle(MAC). Obstruction of the small branch of MAC caused localized filling defect and decreased number of capillaries in the vascular cast. The diameters of vascular cast were reduced at about 22.2% in proximal MAC, 22.4% in distal MAC and 21.8% in first branch of MAC. This results were suggested that ET-1 may play a role in the regulation of blood flow in the anterior segment vasculature of the rabbit.

This case involved a pulmonary thromboembolism, which originated from the lower extremity. A 68-year-old female, with a femur neck fracture, underwent spinal anesthesia with 0.5% heavy bupivacaine 11 mg for total hip arthroplasty. Ten minutes after the induction of spinal anesthesia, dyspnea, tachycardia and hypotension appeared. Under the impression of a pulmonary embolism, intubation was done and dopamine and epinephrine were infused. The operation stopped and she was sent to the intensive care unit. On the spiral CT chest angiogram, a pulmonary embolism was found. Deep venous thrombosis was detected in the left lower extremity on the venogram. Heparin therapy was started at a rate of 800 U/hour with a bolus of 5000 U. A consultative operation for the removal of deep vein thrombosis was performed by a chest surgeon, and total hip arthroplasty was performed successfully under spinal anesthesia.
