This study was conducted to study the life cycle of Haemaphysalis bispinosa and Boophilus microplus. The results obtained are summarized as follows. The period of blood-sucking from a host was 20-25 days (average 22.5 days) for Haemaphysalis bispinosa and was 28-43 days (average 35.5 days) for Boophilus microplus. The parasitism period of Haemaphysalis bispinosa on the host was the same as the blood sucking period, but the parasitism period of Boophilus microplus was only 20-23 days (average 21.5 days) because the Boophilus microplus molted its skin while still on the host. The period from hatching to death for Haemaphysalis bispinosa was 73-123 days (average 101 days) and was 63-92 days (average 77.5 days) for Boophilus microplus. The ticks were waiting on the grass for their host. I could find ticks especially on miscanthus purpurascens, braken, and miscanthus grasses. Larvae had climbed to a height of 15-35 cm and there formed groups of 500. Young adults had climbed to a height of 80 cm and there formed groups from 1 to 5. The number of eggs laid was 2,452 by Haemaphysalis bispinosa and 2,836 by Boophilus microplus. Larvae could not survive the winter. Nymph and young adults of Haemaphysalis bispinosa survived the winter. Boophilus microplus survived the winter as eggs.

It is well known that total colonoscopy is one of the essential procedure to make diagnosis of colonic and terminal ileal diseases, to detect early atage of colonic cancer and to do prophylactic removal of premalignant polyp. Previously commonly used longer colonoscope has been reached to ileocecal area with patients much discomfort arising from excessive loop formation at sigmoid or transverse colon because of no limitation of the length.

PURPOSE: To assess the safety and efficacy of intracorneal ring segment (Intacs ring) implantation in managing keratoconus. METHODS: This retrospective case series comprised of 11 keratoconic eyes (11 patients) had Intacs ring (Addition Technology, Inc, California, USA) implantation. The main outcome measures were best corrected visual acuity, refraction, keratometry, topography, and pachymetry. Patients were examined before Intacs ring implantation as well as one week, one, three, and six months postoperatively. RESULTS: The mean best corrected visual acuity improved from 0.60+/-0.33 logMAR preoperatively to 0.39+/-0.23 logMAR six months postoperatively (p>0.05) and the mean corneal thickness, from 432.82+/-41.17 micrometer preoperatively to 448.00+/-62.27 micrometer at six months (p>0.05). The mean cylinder improved from -5.36+/-2.70D preoperatively to -2.50+/-1.66D six months postoperatively (p<0.05) and the mean keratometry, from 47.99+/-2.38D to 42.83+/-1.72D at six months (p<0.05). In addition, the mean spherical equivalent improved from -6.64+/-3.49D preoperatively to -3.66+/-3.37D six months postoperatively (p<0.05). One eye had a risk of ring exposure, but the others had no significant complications. CONCLUSIONS: Intacs ring implantation appears to be effective in improving cylinder, spherical equivalent, and keratometry in patients with keratoconus.

We experienced three young patients with diffuse lymphoid hyperplasia of the gastric antrum. The peculiar nodularity of the stomach in tliese patients is another cause of etat mammelanne in addition to hypertrophic gastritis and prominence of the areae gastricae. The etiology of the diffuse lymphoid hyperplasia of the gastric antrum is not known. The symptqm is not specific and not related to hitologic and gastroscopic finding but rather to psychological disturbance. We propose longstanding observation for the change of the nodularity.

Among 8, 350 patients seen in the department of ophthalmology, Yonsei University Medical Center from August 1, 1968 to July 31, 1971 there were 2,313 who were seen because of refractive error. These were selected for classification and special statistical study. We reported two similar studies of 2,004 patients having errors in refraction among a total of 9,716 patients seen from August 1, 1958 to July 31, 1961 and 1,919 patients having errors in refraction among a total of 8,796 patients from August 1, 1965 to July 31, 1968 seen in the same department in 1962 and 1968 respectively. The finding of the more recently studied groups are compared with the studies made in 1962 and 1968. 1. 2,313 out of 8,350 patients seen in the department of ophthalmology had errors in refraction (27.7%). 2. 2,949 cases (63.8%) had refractive errors of the myopic type. 626 cases (13.5%) were hyperopic. The others had a simple and a mixed astigmatism. 3. 61.2% of the total group studied had astigmatism. 4. The highest incidence of refractive errors was found between 11 and 20 years of age The older patients had a low incidence. 5. Among the total number of refractive errors 56.3% were found to be in myopic patients who had less than a -3.00 diopters error. 16.8% were found among hyperopic patients who had less than a +3.00 diopters error. 6. Among the three types of astigmatic error seen 1,507 cases (53.2%) were "with the rule", 872 cases (30.8%) were "against the rule", and 456 cases (16.0%) were "oblique". 7. 6.9% of the total refractive errors were those of different types of anisometropia. The most commonly seen type was that of compound myopic anisometropia. The next type seen was simple myopic anisometropia and the least frequently seen type was compound hyperopic anisometropia. 8. When the results of the present study were compared with those found in 1962 and 1968 there are no significant difference between these three groups.

So-called, the double channel pylorus has been, relatively rarely, reported through out the world. All reported cases were almostly those of gastroduodenal fistula as a complication of peptic ulcer disease. The congenital forms of double pylorus were reported even more rarely. We found three cases of double channel pylorus in 25,000 cases endoscopy done at our unit. All those three cases were thought to be acqired form endoscopically, radiographically and histologically. One of those was undergone to operative resection because of uncontrollable bleeding and the others were on medical theraphy with satisfaction.

PURPOSE: To evaluate the change of iris-trabecular contact index (ITC index) after cataract surgery in acute angle closure glaucoma. METHODS: Twelve patients (17 eyes) who had a history of acute angle closure glaucoma underwent swept source optical coherence tomography before and after cataract surgery. Correlations between lens vault (LV), ITC index and intraocular pressure (IOP), anterior chamber depth (ACD), anterior chamber volume (ACV), and angle parameters were analyzed before and after cataract surgery. RESULTS: IOP (p = 0.007), ACD (p < 0.001), ACV (p < 0.001), angle parameters (p = 0.001), and ITC index (p = 0.012) were improved after cataract surgery. ITC index decreased from 88.42 ± 23.59% to 48.91 ± 35.13% after cataract surgery (p = 0.012). There was no correlation between LV and ACD (p = 0.075), ACV (p = 0.864), angle parameter (p = 0.112-0.707), or ITC index (p = 0.288) before cataract surgery. The correlations between ITC index and IOP (p = 0.021), ACD (p = 0.002), ACV (p < 0.001), and angle parameter (p = 0.001-0.030) were statistically significant before surgery but not statistically significant (p = 0.223/0.206/0.761/ 0.096-0.819) after surgery. CONCLUSIONS: ITC index significantly improved after cataract surgery, but part of angle closure was not resolved in some cases of acute angle closure glaucoma.

PURPOSE: To evaluate the clinical features of subretinal hemorrhage after photodynamic therapy in eyes with exudative age-related macular degeneration. METHODS: We retrospectively reviewed data for 267 eyes of 243 patients who had undergone PDT for the treatment of ARMD between January 2005 and December 2006. Best corrected visual acuity, fundus photography, fluorescein angiography, and ICG angiography were performed before and after treatment. We followed up the patients at 1 week, 1 month, and 3 months after treatment and at 3-month intervals thereafter. RESULTS: Postoperative subretinal hemorrhage was seen in 36 (13.4%) of 267 eyes. The pretreatment and post-treatment mean visual acuities were logMAR 0.80 and logMAR 1.05 respectively, representing a decrease of 2.05 lines. On FAG, two eyes were predominantly classic, four eyes were minimally classic, and 30 eyes were occult. The laser irradiation spot size was under 3,000 micrometer in one case and from 3,000 micrometer to 5,000 micrometer in 19 cases and over 5,000 micrometer in 16 eyes. CONCLUSIONS: Subretinal hemorrhage after PDT for ARMD can be a common complication in patients who have been treated for larger irradiation spot sizes and for pigment epithelial detachment (PED), so doctors should be aware of the risk of serious hemorrhagic complications in such situations.

Budd-Chiari syndrome is acute or subacute occlusion of the hepatic vein and IVC, The occlusion of hepatic veins often reveals dramatic illness characterized by abdominal pain, ascites, hepatomegaly and a poor prognosis. Several recent reports have suggested that balloon dilatation may be effective in Budd-Chiari syndrome. We experienced a case of Budd-Chiari syndrome with IVC web which was successfully treated with balloon dilatation. We report the case here with a brief review of literature,

OBJECTIVES: To investigate the incidence of antiphospholipid antibodies in patients with proven endometriosis and apparently normal controls, and to evaluate the changes in profiles of humoral immune factors in endometriosis after treatment with gonadotropin releasing hormone agonist (GnRHa). METHODS: Sera of 92 patients with endometriosis, 40 patients without endometriosis and 128 normal male blood doners (normal controls) were tested for the presence of autoantibodies to six phospholipids (cardiolipin, phosphatidylserine, phosphatidyglycerol, phosphatidylethanolamine, phosphatidylinositol, phosphatidic acid) and beta 2-glycoprotein I(GPI)- dependent anticardiolipin antibodies. Also, antiendometrial antibodies (AEA), antiphospholipid antibodies (APA), Immunoglobulin (Ig)G, IgA, IgM, complement C3, C4 and CA-125 were measured in 26 endometriosis patients before and after 3 months of GnRHa treatment. RESULTS: Eighteen (19.6%) patients with endometriosis had at least one of the APA compared with normal controls (8.3%). The prevalence of beta 2-GPI-dependent anticardiolipin antibodies was higher in patients with endometriosis than in normal controls. There were no significant changes in the positivity and levels of AEA and APA after GnRHa Treatment and the levels of immunoglobulins and complement showed similiar pattern. However, the numbers of patients with the level of CA-125 > 35 IU/ml, which is defined as the upper limit of normal level and the levels of CA-125 decreased. CONCLUSIONS: Around 20% of patients with endometriosis had APA and CA-125 measurement may be better than humoral factor tests in monitoring patients with endometriosis after GnRHa treatment.
