The Parasitological investigation on the encysted metacercariae in brackish water fish, Tribolodon taczanowskii, in the downstream of Hyungsan river which is located in Kyungpook Province of Korea, were carried out serially and the following results were obtained. Metacercariae of Pseudexorchis major were found in six fishes(15.8 per cent ) out of 38 examined. Parasitic frequencies of the encysted metacercaria of Psedexorchis major in Tribolodon taczanowskii were 15.8 per cent (6 out of 38) in the scale, 10.5 per cent (4 out of 38) in the fin, 13.2 per cent (5 out of 38) in the gill, 10.5 per cent (4 out of 38) in the oral cavity and 7.9 per cent (3 out of 38) in the flesh. The worms were identified as Pseudexorchis major (Hasegawa, 1935) Yamaguti, 1938 by morphological studies on the metacercariae, excysted metacercariae, adults and eggs, and compared with prereported Pseudexorchis species.

One hundred fifty bacteriae isolated in significant numbers from 96 specimens of urine of the 45 in-patients with long-term indwelling catheter were evaluated from January, 1978 to July. 1979 and the following results were obtained; 1. In 20 patients (44.4%), positive urine culture was obtained within 10 days after indwelled catheter in the urinary tract and 97.9% of the patients revealed the positive urine culture within 20 days after that. 2. Of 150 bacterial strains isolated by cultures of the urine, 96% was gram-negative bacteria and 4% was gram-positive. Isolated organisms included klebsiella(27.4%), E.coli(23.3%). proteus(14.7%), pseudomonas(12.0%). coliform bacilli(10.0%). other gram-negative organism (8.6%), staphylococcus(2.7%) and streptococcus (l.3%) in order of frequency. 3. In 4 patients(8.9%), bacteremia was developed. Isolated organism from blood culture and those from urine culture were same. The mortality rate was 50%.

Animal models for human chronic pain syndromes were developed and widely used for pain research. One of thsese neuropathic pain model by Kim and Chung[1992] has many advantages for operation and pain elicitation. We have examined the c-fos protein, substance P, CGRP immunoreactivity in dorsal root ganglia and dorsal horn in this neuropathic model. About 50 Sprague-Dawley rats were used for this study. L5 and L6 spinal nerve were ligated tightly to produce neuropathic pain model. After 2, 4, 8, 16, 24 hours and 1 week of surgery, rats were anesthesized and sacrificed by perfusion through the left ventricle with saline followed by 0.1M phosphate buffer[pH 7.4] containing 3% paraformaldehyde, 3% glutaraldehyde, and 0.1% picric acid. After confirmation of the roots transected by the surgery, the L5 and L6 dorsal root ganglion and spinal cord were removed and processed for immunohistochemistry. All tissue sections were immunohistochemically stained for substance P, CGRP and c-fos by using the peroxidase-antiperoxidase[PAP] method. Count the number of immunostained substance P and CGRP dorsal root ganglion cells and c-fos immunoreactive dorsal horn cells and analyzed statistically with Mann-Whitney U test. The results are as follows. 1. The number of c-fos protein immunoreactive neurons in the superficial layer of dorsal horn were increased markedly at 2 hours after operation, gradually decreased to normal level 1 week after operation. 2. The number of c-fos protein immunoreactive neurons in the deep layer of dorsal horn were gradually increased to the peak 24 hours after operation, decreased to normal level 1 week after operation. 3. The number of substance P and CGRP immunoreactive L5 and L6 dorsal root ganglion neurons were decreased markedly at 1 week after pain model operation. In conclusion, after neuropathic pain model operation, c-fos protein were immediately expressed in the superficial layer of spinal dorsal horn, thereafter c-fos protein in the deep layer of spinal dorsal horn were expressed. CGRP and substance P immunoreactive neurons were decreased markedly 1 week after neuropathic pain model operation.

Dermatofibrosarcoma protuberans (DFSP) is a rare, distinctive cutaneous tumor, which consists of spindle shaped ceils arranged in densely packed interlacing bundles with the storiform or cartwheel pattern. Histologically, it resembles deep growing dermatofibroma, nodular fasciitis, neurofibroma and neural sheath tumors. DFSP is one of t.he connective tissue tumors which is difficult. to diagnose histologically as well as clinically. Recently, the immunochemical staining with a monoclonal antibody to CD34 is reported to give assistance in the clear differential diagnosis of DFSP from other fibrous or neural tumors. Herein, three cases of DFSP were stained by immunohistochemical staining with S-100 protein, vimentin, factor VIII and anti-CD34 antibody in order to assess the use of anti-CD34 in the differential diagnosis of DFSP.

The purpose of the study is to describe the cases with prepapillary or peripapillary vascular malformation who have experienced mild vitreous hemorrhage. Five patients [5 eyes], 1 male and 4 females, were included in the study.The vascular malformation was unilaterally present in all patients.Vitreous hemorrhage occurred from the area of retinal vascular malformation near or on the optic nerve, and cleared without further complications. Fluorescein angiographic feature of each eye was normal. Arteriovenous communication, secondary retinal exudation, or vascular leakage from vascular malformation was not observed. Each patient showed improvement in visual acuity of 2 lines or more. This benign, congenital vascular malformation may be non-progressive and infrequently cause mild vitreous hemorrhage.Therapeutic intervention was not necessary in these cases.

The case reported here, concerns a spontaneous low-flow fistula between the carotid arterial network and the cavernous sinus, with ophthalmological symptoms such as conjunctival congestion and diplopia in a 41-year-old woman. The patient has suffered from diabetes without trauma history. Patient's ocular symptoms and signs were only present in the left eye with best-corrected visual acuity 0.04 at the time of presentation. Other ophthalmic findings were exophthalmos, elevated intraocular pressure, and visual field defects. Enlarged extraocular muscles and proptosis were found on orbital computed tomography leading to the misdiagnosis of orbial pseudotumor or thyroid rbitopathy. Carotid angiography showed dural carotid-cavernous sinus fistula, which involved left-side internal and external carotid arterial network and right-side internal carotid arterial network. Orbital color Doppler imaging showed a flow reversal with a systolic component in the enlarged superior ophthalmic vein. We were able to diagnose dural carotid-cavernous sinus fistula. Dural carotid-cavernous sinus fistula was closed successfully by embolization via the vein without omplication. The visual acuity, proptosis, and dilated and tortuous vessels of the conjunctiva improved.

Mobility shifts in non-denatured gel electrophoresis of PCR-amplified Rif' region in each of fifteen different mutants of M. tuberculosis were discerned by single strand conformation polymorphism (SSCP) analysis. The findings of mobility differences between rifampin-resistant and susceptible strains showed an excellent agreement with data obtained by traditional susceptibility test. SSCP-PCR seemed to replace the cultivation method of susceptibility test that was known to be time-consuming, labor wasting, and skeptical in quality control. After screening of rpoB gene mutation by SSCP-PCR, detection of specific sequence changes in the region of rpoB gene was attempted through the procedures of PCR-amplification, cloning of PCR-products using pGEM-T vector and DNA thermocycling sequencing. Fifteen different types of mutations were identified among fifty strains of rifampin-resistant strains while five rifampin-susceptible control strains showed no sequence changes of rpoB gene as well as reference strain H37rv. Most mutation appeared to be a point mutation due to substitution or deletion except seven mutants showing somewhat complex mutation. Each of mut#ated loci inclined to clustering within a region of eighteen amino acids involving eight codons. The most common mutation of Ser425 shared among twenty-nine mutants and followed by eleven mutants of His420. Several mutants alleles identified in this study appeared to be dissimilar to those of previous reports.

PURPOSE: To report a case with proptosis associated with orbital panniculitis. METHODS: A 34-old-year man with unilateral proptosis for 1 month presented with diffuse swelling and redness in the eyelid and conjunctiva. His systemic symptoms were high fever, headache, nausea, diarrhea, dizziness, weight loss, malaise and hepatosplenomegaly. He had subcutaneous nodules on the inguinal region, the pubis, and the upper abdomen. Ophthalmic examinations, orbit magnetic resonance imaging(MRI), and biopsy from orbital tissue were performed. RESULTS: The right eye revealed proptosis(22/14/102, Hertel's exophthalmometer), but other ocular findings including the fundus were normal. Diffuse infilterative lesions and definite proptosis were shown on orbit MRI. Biopsy specimen of orbital tissue revealed histiocytes containing nuclei and nuclear debris, mononuclear cells infiltration, and the characteristic 'bean-bag' cell i.e., macrophage exhibiting hemophagocytosis, which is histopathological characteristic of cytophagic histiocytic panniculitis. Proptosis, swelling and redness of the eyelid improved gradually following systemic corticosteroid therapy to control the disease. CONCLUSION: This report describes a rare finding of proptosis as the manifesting sign of orbital panniculitis.

Heart transplantation is an accepted procedure for treatment of end-staged cardiac failure. A return to near-normal quality on life can be expected in many patients with a nonrejecting cardiac allograft, and many of these patients will return to the operating room for noncardiac surgical procedures. Anesthesiologists should be alert to recognizing problems caused by the presence of infection in immunosuppressed patients, modes of presentation of rejection phenomena and how transplanted organs, notably significantly denervated ones, may behave and respond under the pathophysiologic circumstance that arise during surgery, resuscitation and intensive care. The use of regional techniques require adequate preloading to avoid exaggerated hypotension and aseptic technique to avoid infection. Hypobaric spinal anesthesia has some benefit. It does not depress cardiovascular and respiratory system and keep adequate venous return by trendelenberg position. We report herein a case of successfully undergone total hip replacement in a patient who had previously undergone orthotopic heart transplantation under hypobaric spinal anesthesia.
