The changes in the size of human oviduct and ovary after immersion in formalin (4%, 10%) were investigated. The results were as follows : 1. After fixation, the length of oviduct was significantly reduced to 93%, but the cross sectional area of oviduct was significantly increased. The length of oviduct showed no significant difference between 4% and 10% formalin. The length of ovarian ligament was also significantly reduced to 84% after fixation. 2. After fixation, the volume of oviduct was increased significantly and showed a difference between the two fixatives. The volume of oviduct in 4% formalin has increased to 107%, as compared to 103% increase in 10% formalin. 3. After fixation, the volume of ovary was increased significantly and showed a difference between the two fixatives. The volume of ovary in 4% formalin has increased to 109%, as compared to 103% increase in 10% formalin.

3.Taxonomic Studies on Alternaria in Korea (1).

Mycobiology 2001;29(1):27-42
The taxonomy of the Alternaria spp. has been a subject, of controversy because of their high variability in conidial morphology and polymorphism displayed even in pure cultures. The published Korean literature on the genus Alternaria is scattered and fragmentary, and pertains to about 25 species with special emphasis on occurrence and pathogenicity, but mycological studies on this group of fungi are insufficient. This is the first series of detailed and consolidated account of Korean species of Alternaria, which includes 11 species; viz., Alternaria brassicae, A. brassicicola, A. cinerariae, A. dauci, A. dianthi, A. dianthicola, A. helianthi, A. helianthinffciens, A. iridicola, A. japonica and A. protenta. Detailed diagnostic descriptions, specific characterizations, taxonomic discussions and illustrations for each species are presented.

4.Venous Stasis and Ulceration Due to Congenital Absence of Inferior Vena Cava
Journal of the Korean Society for Vascular Surgery 1998;14(1):136-139
Congenital absence of inferior vena cava is an uncommon abnormality. With advent of modern imaging techniques such cases are being found with increasing frequency. I report the case of an otherwise healthy 44-year-old man with severe venous insufficiency involving both lower extremities manifested by multiple ulcerations. This condition was caused by a combination of congenital and acquired factors. Ulcerations were managed successfully with aggressive conservative treatment.

8.Benefits of a Cholecystostomy and Review of 1000 Consecutive Laparoscopic Cholecystectomies.

The laparoscopic cholecystectomy, performed for the first time in France in 1987, has been accepted as in many countries the method of choice when performing a cholecystectomy. The trend toward minimally invasive surgery has prompted general surgeons to try it instead of open cholecystectomy. We performed 1000 laparoscopic cholecystectomies at the Department of General Surgery of Eulji Medical College Hospital from January 1992 to April 1997. The outcome data have been analyzed retrospectively. Moreover, we have compared the case histories of 13 patients who received cholecystostomy with those of 43 patient who did not. We also present preliminary results for an interval laparoscopic cholecystectomy which was a preceded by percutaneous cholecystostomy. The results are as follows: 1) The mean age was 54.3 years ranging from 17 to 86; there were 402 males and 598 females. 2) Of the 1000 patients, 123 patients (12.3%) had a history of abdominal surgery. 3) More than half of the patients(560 patients, 56.0%) underwent operations within 6 months of the onset of symptoms. 4) A preoperative endoscopic retrograde cholecystoscopy was performed on 220 patients (22.0%), and of these, 93 patients received endoscopic sphincterotomies because of bile duct stones. 5) The majority of patients(744 patients, 74.4%) had laparoscopic cholecystectomies which lasted 40 minutes or less. 6) More than half (54%) of the removed gallbladders showed grade II inflammation. 7) Drains were used in 142 patients (14.2%). 8) Postoperative complications were encountered in 48 patients (4.8%). 9) Postoperative oral intake was resumed within 24 hours in most patients. 10) Most patients(854 patients, 85.4%) were discharged within 3 days of the operation. 11) The pathologic diagnosis was chronic nonspecific inflammation in most cases (823 cases, 82.3%). 12) The most common microorganism in the bile was E. coli. 13) Patients who received a cholecystostomy had many benefits: a shorter operation time, a low rate of open cholecystectomy, early oral intake. 14) For the 1160 patients who underwent a cholecystectomy during the same period, the rate of open cholecystectomy was 13.8%.

9.Genetics of Hereditary Peripheral Neuropathies.
Journal of Genetic Medicine 2009;6(1):25-37
Hereditary peripheral neuropathies can be categorized as hereditary motor and sensory neuropathies (HMSN), hereditary motor neuropathies (HMN), and hereditary sensory neuropathies (HSN). HMSN, HMN, and HSN are further subdivided into several subtypes. Here, we review the most recent findings in the molecular diagnosis and therapeutic strategy for hereditary peripheral neuropathies. The products of genes associated with hereditary peripheral neuropathy phenotypes are important for neuronal structure maintenance, axonal transport, nerve signal transduction, and functions related to the cellular integrity. Identifying the molecular basis of hereditary peripheral neuropathy and studying the relevant genes and their functions is important to understand the pathophysiological mechanisms of these neurodegenerative disorders, as well as the processes involved in the normal development and function of the peripheral nervous system. These advances and the better understanding of the pathogenesis of peripheral neuropathies represent a challenge for the diagnoses and managements of hereditary peripheral neuropathy patients in developing future supportive and curative therapies.

The variations of the sigmoid sinus were studied in 50 Korean adults (average age 67). The classification of the shape and a measurement of the diameters of the sinus were done and the morpological. 1. The shape was classified into 4 types, and the round type was the most common in both sides. S shaped type was below 10% in both sides. 2. The breadth was regular in 54% of the right and in 70% of the left sinuses. According to the breadth change, the shape was classified into 4 shapes. 3. The average diameter was 8.6mm on the right side and 7.2mm on the left side. 4. Symmetry was present in 16% of all. 5. The right transverse sinus was absent in 1 case (2%) and the superior petrosal sinus did not open into the sigmoid sinus in 2 cases (4%). 6. Petrosqamous sinus was observed in 16%.
