A 52-year-old man with multiple myeloma developed cutaneous nodules while being treated with melphalan and prednisolone. A biopsy specimen showed dermal infiltration by well differentiated plasma cells similar to those found on bone marrow biopsy. The use of peroxidase anti-peroxidase to demonstrate the monoclonality or polyclonality of the cytomplasmic immunoglohulins in the tumor cells revealed a positivity for IgG and 1 chain (ie, monotypic staining). Ultrastructurally, each plasmacytoma cell contained varyting amounts of rough endoplasmic reticulum and Golgi-apparatus. The cutnneous nodules completely disappeared after radiotherapy

Ovarian leiomyoma is a rare form of the ovarian mesenchymal neoplasm and about 50 cases have been reported in the literature. It is believed that many cases may go unnoticed because they are usually small in size and frequently mistaken for the more common fibroma or fibrothecoma. Its origin is still controversial and many possibilities are considered including the smooth muscle in the blood vessel wall of the hilum or the multipotential ovarian stromal cell. Herein we describe two cases of ovarian leiomyoma with its characteristic histologic finding.

The toxic action of benzene on erythropoiesis and myelopciesis, has been recognized since the early years of the present century. With the advance in high civilization and modern covenience, benzene as a kind of aromatic compound has been used for industrial solvent and its longstanding use has committed a public nuisance to be overcome by medical approach. Chromosomal breakage and rearrangement may be produced by radiation, radiomimetics, virus infection and various chemicals, especially, antibiotics and antitumor agent, causing chroimosomal rearrangement in vitro, whose teratogenic action in rats was previously demonstrated. Several works hsve been published on the chromosome damage as a consequence of benzene intoxication. Recently, it was shown by certain workers that individuals who had been exposed to atmospheric benzene, even without haematological disorders, might have an elevated percentage of structural chromosome aberrations in the lymphocytes cultured from their peripheral blood. Moreover, structural and numerical chromosome aberrations were demons trated in patients with blood disorders which were believed to be due to exposure to beuzene vapors. Accordingly, much interest has been paid to its cytologic effect on the hematopoietic tissues in man and experimental animals. A high incidence of chromosomal aberrations has also been found in rabbits exposed to benzene during a period of peripheral pancytopenia and after hematologic recovery. The significance of these findings was discussed in relation to leukemic transition and to their diagnostic value in human benzene intoxication. Chromosomal anomalies can also be induced by benzene given subcutaneously to rata. A pronounced individual variation of the degree of chromosome damage was shown. The purpose of this investigation was to determine whether benzene could a direct effect on the chromosome complement of mammalian bone marrow cells in vivo and whether characteristic banding patterns might be demonstrated in rat chomosomes by a modified trypsin-Giemsa method. Four-week old Sprague-Dawley strain rats of both sexes(each weighing about 50gm) were used for this experimental study. Three groups of animals were treated-with subcutaneous infections of pure benzene. Group I received benzene, 2.0ml per kg body weight, 24 hours before sacrifice; Group II, 48 and 24 hours and Group III, 72, 48 and 24 hours. A control group was given no treatment. The animais were sacrificed in ether anesthesia. Femur and iliac bone marrow cells were suspended in medium 199 within 30 minutes and transferred to warm Hanks-distilled water(1:3) for hypotonic treatment(10 minutes). A freshly prepared solution of methanol glacial acetic acid (3:1) was used as fixative. Finally, a few drops of the cell suspension were placed on moistened, pre-cleaned slides being dried by rapid-drying technique. The slides were stained with either simple Giemsa or trypsin Giemsa banding technique. From the data obtained, this report was summarized as follows: 1. For the benzene-treated groups, chromosomal aberration rate was 13.4% in group II and 38.6% in group III, while in the controls the rate was 6.4 percent. 2. Numerical aberrations included aneuploidy, polyploidy and monoploidy. The most frequent type was hypodiploidy (5.8–9.4%) in all the treated groups. 3. Structural aberrations could be divided in gaps, ring chromosomes, breaks, deletions, exchanges and dicentrics. Among those, the majority of abnormal metaphases was gaps; 2.4%, 2.2% and 10.8% in group I, II and III respectively, and 1. 6% in control group. 4. The translocations and dicentrics were not demonstated in group I and II. 5. The normal chromosome set of the Sprague-Dawley rat was comprised of 42 chromosomes: 20 pairs of autosomes, and one pair of sex chromosomes, xx or XY chromosomes. The total number of major bands in s chromosome complement was about 40 and minor bands, 13, 6. Sucessful demonstration of banding patterns was available by proper adjustment of the concentration, temperature and duration of trypsin solution.

Recently, the number of surgeries with age-related cataracts has increased remarkably high due to the safety of modern cataract surgery and reliable post-operative visual function has been widely recognized by patients. In spite of such an increase in the number of patients, the authors specualtes that there are still many cataract patients with highly deteriorated visual function who havehad no occasion to receive an ocular examinatio. In order to screen such patients during their general health examination, the authors` study group experienced and evaluated the simplified cataract screening system recently proposed by Sasaki et al, Kanazawa Medical University in Japan. The cataract screening system consists of two steps; primary screening system is 12-item questionnaires, and far vision. In order to evaluate the screening system in Korea, it was used to test 224 indivisual who had wanted to be examined ophthalmologically in two area, Yongsan, Seoul and Donghae, Gangwondo province. Initially, well-trained nurse did the screening system, and then the same patients were examined by one ophthalmologist. The agreement ratio between the screening test and the final judgement for cataract was 70.8% and the final cataract-screening rate was 95.1%. Based on these results, the authors propose the possibility of clinical use of this screening system in general health care units.

The authors present that was diagnosed late panophthalmitis histopathologically and that was a case of 17 scheie's filtering operated eyes during last 2 years. The patient was 63 year-old male who had chronic narrow angle glaucoma associated with moderate optic nerve cupping and atrophy in both eyes a year ago. Good filtering bleb showed and intraocular pressure controlled well normally after Scheie's operation in right eye. One year and five months later acute suppurative endophtbalmitis occured in operated eye during catarrhal conjunctivitis in both eyes. The authors concluded that the route of infection was filtering fleb. Culture of excreting pus through ruptured filtering fleb was negative.

Cataract and refractive surgical procedures are now among the most common and successful in medicine. A clear understanding of the current situation and future trends in these fields has become increasingly important. Since 1995, we have annually surveyed the members of the Korean Society of Cataract and Refractive surgery(KSCRS) about cataract surgery technique, anesthesia, intraocular lens and refractive surgery. Third annual survey forms consisted of 71 multiple-choice questions were mailed in January 1998 to 180 ophthalmologist members of the KSCRS. Approximately 44% of the questionnaires mailed were returned by the February cutoff date. Current data were compared with data in previous annual survey. Over half of the respondents(52%) were in forties. Most of the cataract operation(83%) was carried out on hospitalized patients. Use of a retrobulbar with akinesia for cataract was 49%, and use of topical anesthesia increased from 5% in 1995 to 17% in 1996. Eight-one percent of surgeons used phacoemulsification for more than half of their patients. Selfsealing wound construction was main wound closure technique in phacoemulsification for 44%. The type of intraocular lens used for small incision cataract surgery included silicone(64%), small round PMMA(polymethyl methacrylate, 21%), and acrylic(11%). Sixty-three percent of surgery. From the answers to the survey, we found current trend and these results are valuable information to all ophthalmologists.

PURPOSE: This study was performed to evaluate the effect of TGF-beta on proliferation, collagen synthesis, migration, and matrix metalloproteinase (MMP) secretion of human RPE cells in vitro. METHODS: The cultured human RPE cells were treated with either TGF-beta1 or TGF-beta2 in concentrations of 0, 0.1, 1, 10 ng/ml respectively. The cell number was measured in 3, 6, 9 days, and the collagen synthesis and cell migration was measured. [3H]-thimidine uptake assay was done to evaluate the change of DNA synthesis. And the secretions of MMP1, MMP2, MMP3, MMP9, TIMP1 (tissue inhibitor of metalloproteinase), and TIMP2 were measured by electrophoresis and Western blot analysis. RESULTS: TGF-beta1 and TGF-beta2 significantly inhibited the proliferation of RPE cells in a concentration -and time-dependent manner (p<0.05). [3H]-thymidine uptake was decreased by TGF-beta1 and TGF-beta2 in a concentration-dependant manner. The collagen synthesis of RPE cells was significantly increased by high concentration of TGF-beta1 and TGF-beta 2. However, the migration of RPE cells was not affected by TGF-beta. As the concentration of TGF-beta1 and TGF-beta2 increased, the secretions of MMP1, MMP2, MMP3 and MMP9 decreased, while the secretion of TIMP1 and TIMP2 increased after 72 hours. CONCLUSIONS: These results suggest that the TGF-beta1 and TGF-beta2 may have critical effect on the development of PVR and provide clues to possible therapeutic solutions for controlling PVR process.

At the present time, lidocaine is commonly used in ophthalmic surgery as a local anesthetic. Although it is safer than general anesthesia, visionthreatening and even life-threatening side effect can occur rarely. We report one case of visual loss combined with severe neurologic damage after local injection of lidocaine. Fifty-year-old male patient underwent phacoemulsification and IOL transscleral implantation with unplanned anterior vitrectomy after Nadbath-Ellis akinesia and retrobulbar anesthesia with lidocaine with 1:100,000 epinephrine. After operation, the patient had visual loss, facial palsy, total ophthalmoplegia, severe proptosis and submandibular swelling. There were no evidences of eyeball perforation, retrobulbar hemorrhage, and direct nerve injury. Although the mechanism of nerve injury is not well explainable, we suggest lidocaine toxic reaction. To our knowledge, This is the first reported case in the literature. We report this case with available literature review.

An important aspect of plastic surgery is skin flap survival. Among the prostaglandins, PGE4 is used clinically to improve peripheral circulatory disturbances due to its action of augmenting blood flow by vascular smooth muscle relaxation and its strong inhibitory action of platelet aggregation. Clinically, many investigators found that the effect of PGE4 was prolonged for a long period even after short-term application. So a new hypothesis emerges that the prolonged effect of PGE4 may be due to neovascularization and not due to vasodilatation alone. This study was designed to clarify the mechanism of the prolonged effect of topical PGE4 with regard to angiogenesis. A total of 9 male hairless mice were treated with a topical application of PGE4 onitment (PGE4 powder mixed in hydrogen base) on the experimental side and only a hydrogen base on the contralateral control side of the back skin, respectively, for 7 days, once a day. Then they were divided into 3 groups. In group 1, specimens were obtained on the 7th day post-treatment using 3 mm size punch biopsy from both sides. In group 2, specimens were obtained on post-treatment 14th day. In group 3, specimens were obtained on post-treatment 28th day. The number of blood vessels were compared between the experimental side and control side with respect to neovascularization after PGE4 application using an image-analysis program under hemtoxyline-eosin stain. Treatment on the experimental side did not affect its contralateral mate, since there was no evidence of a systemic effect. From our experimental data, we could conclude that PGE4 may induce angiogenesis by topical application without systemic effect.
