The author obtained index of red cell volume distribution width(RDW) and other red cell indices in 210 patients of various hematoncologic conditions and 200 healthy control group using, an automated blood analyzer, Coulter Counter Model S-plus II. This study performed to classify various etiologic anemia based on the MCV and RDW, to evaluate availability to the differential diagnosis in korean anemic distoders somewhat different from etiologies of anemias in foreginers. In the most of cases, the increase or decrease of MCV were always combined the pararell changes of MCH and MCHC: But the values of MCV and RDW were not correlated in control group and patient group. So the terms of heterogenous of homogenous anemia were meaningful morphologic classification than hypochromic or normochromic anemia. The heterogenous microcytic anemia contained iron deficiency anemia. In heterogenous normocytic anemia, myelophthisic anemia, acute leukemia were contained. In heterogenous macrocytic anemia, megaloblastic anemia, hemolytic anemia were contained. The homogenous microcytic anemia was observed in anemia of chronic disorders. In homogenous normocytic anemia, acute blood loss, chronic leukemia, multiple myeloma were contained. The aplastic anemia was belonged to homogenous macrocytic anemia. The diagnostic significance of RDW in hemoglobinopathies is most importhant. But this study was not contained hemoglobinopathies. Instead RDW was very helpful to differential diagnosis of most common anemias, iron deficiency anemia and anemia due to chronic disorders in Korea.

BACKGROUND: The HLA system is known to be the most polymorphic genetic system in human and there are characteristic racial differences in the distribution of HLA antigens, alleles, and haplotypes. This study was performed to examine the frequency of HLA antigens, alleles and haplotypes in Koreans. METHODS: Two thousand healthy Koreans registered for unrelated bone marrow donors were subject to the study. HLA-A, B and C antigens were typed by the serological method, and HLA-DR DNA typing (low resolution) was done by PCR and reverse hybridization. HLA allele and haplotype frequencies and linkage disequilibrium values were calculated by the maximun likelihood method using the computer program of the 11th International Histocompatibility Workshop. RESULTS: HLA antigens identified in 2000 Koreans were 14 in A locus, 33 in B locus, 8 in C locus and 12 in DR locus. Alleles showing frequencies of more than 10% in decreasing order of frequency In each HLA locus were A2, A24, A33, All, B44, B62; CBL, Cw3, Cwl, Cw7, DR4, DR2, DRl3, DR8, and DR9. Among A-B, C-B, B-DR 2-locus haplotypes, A33-B44, A30-B13, Al-B37, Cwl-B54, Cw4-B62, B7-DR1, B37-DR10 showed strong positive linkage disequilibrium (Chi-square > 1000). The most common A-B-DR haplotypes in Koreans occurring at frequency of more than 2% were A33-B44-DRl3 (4.8%), A33-B58-DRl3 (3.2%), A33-B44-DR7 (2.6%), All-B62-DR4 (2.3%), A24-B7-DR1 (2.3%), and A30-Bl3-DR7 (2.1%) Comparison of the distribution of A-B-DR haplotypes among east Asian populations reveals that Koreans are most close to Japanese, but show higher degree of polymorphism in the distribution of HLA haplotypes compared to Japanese. CONCLUSIONS: The results obtained in this study can be used as basic data for Koreans in the fields of organ transplantation, disease association studies and anthropologic studies.

A clinical review of 31 cases of multiple myeloma which were diagnosed by criteria of the SWOG between May 1983 and February 1990 at Yeungnam University Hospital was done. The results were as followings: 1. The peak incidence was in 7th decade and male to female ratio was 1.8:1. 2. The most common presenting symptom at first diagnosis was bone pain (58%), but fever, dyspnea, dizziness and palpable mass were also noted. 3. The distribution of laboratory findings as following diagnostic criteria of Southwest oncology group (SWOG): Plasmacytoma on tissue biopsy was noted 6 cases, bone marrow plasmacytosis with more than 10% plasma cells was 22 cases, monoclonal globulin spike on serum electrophoresis was 24 cases, lytic bone lesions was observed 22 cases. 4. Initial clinical stages were classified as 2 cases in stage I, 3 cases in stage II, 26 cases in stage III (84%). 5. Immunoelectrophoresis revealed the distribution of IgG 64%, light chain 22%, IgA 10%, Kappa to Lambda ratio of 1.1:1. 6. Hematologic & biochemical findings revealed anemia with <8.5% of hemoglobin in 42%, hypercalcemia with <10.6 mg% of serum calcium in 22%, azotemia >2.0 mg% of serum creatinine in 19%. 7. The multiple punched out lesion of bone x-ray examination were noticed skull (65%), rib (42%), L-spine (35%), pelvis (23%), T-spine (19%). The initial skeletal roentgenographic findings showed osteoporosis, osteolytic lesion and fracture in 55%, only osteolytic lesion in 23%, only osteoporosis in 10%. 8. Complications of multiple myeloma, such as 10 cases of renal impairment, 8 cases of infection, 16 cases of compression fracture of spine were observed.

OBJECTIVE: To compare the age of menarche, changing patterns of the menstrual characteristics in adolescent girls between 1988 and 1998. METHODS: A survey was undertaken for 1,500 highschool girls and compare with those of pervious study for 5,000 middle and highschool girls performed by same author in 1998 by means of questionnaire. RESULTS: During a decade, the mean menarcheal age decreased from 13.5+/-1.0 to 12.7+/-1.0 years(p=0.001). Gynecologic age, Body mass index were associated with age of menarche in both 1988 and 1998. The interval of menstruation was 30.6 3.5dyas in 1998 and shortened compared with 32.1+/-6.3 days in 1988(p=0.001). The duration of menstruation was lengthened in 1998 than in 1988(6.1+/-1.1 days vs 5.8+/-2.2 days, p=0.001). The incidence of irregular cycle(28.2% vs 58.2%, p=0.001), dysmenorrhea(73.9% vs 77.8%, p=0.001), and secondary amenorrhea(16.2% vs 27.2%, p= 0.001) decreased in 1998 compared with those of 1988. The incidence of agonies about menstruation was also decreased in 1998 than in 1988(26.2% vs 69.1%, p=0.001). The most common agony about menstruation in 1988 was irregular cycle(28.4%), but dysmenorrhea( 64.3%) in 1998. CONCLUSIONS: From the above results, the mean age of menarche was advanced since last decade but most of the adolescent girls still have suffered from dysmenorrhea.

Collagen is the major structural protein in the human body, especially in connective tissues. There are more than 13 types of collagen. Among them, type II collagen is a main component of articular cartilage structure. Altered immunological conditions against type II collagen may be closely related to the pathologic conditions of joint, especially arthritis. Since 1977, animal model for collageninduced arthritis(CIA) has been developed and used in the investigation of arthritis. In those animals, high titers of anti-type II collagen antibody were noticed. Pathologic findings were similar to rheumatoid arthritis of human, which suggested that rheumatoid arthritis might be one of the autoimmune diseases. There had been many reports about elevation of serum and synovial level of anti-type II collagen antibody in rheumatoid arthritis patients. But majority of them did not discriminate the antibody titers according to the type of immunoglobulin(i.e. IgG, IgM). And the question whether the elevated antibody titers are cause or effect of the arthritis is still in controversy. In this study, the serum levels of anti-type II collagen antibody were determined in 82 persons(35 degenerative arthritis patients, 24 rheumatoid arthritis patients and 22 normal controls without any joint problem) via ELISA method. In each person the serum IgG, IgM and IgG+M+A antibody levels against bovine type IIcollagen and chicken typeII collagen were determined individually. Statistical evaluation of these data among degenerative arthritis group, rheumatoid arthritis group and normal control group was performed. The results were as follows; 1. Degenerative arthritis group revealed significant elevation of anti-type II collagen antibody(IgG, IgG+M+A) compared to normal control(p < 0.05). 2. Rheumatoid arthritis group showed significant elvation of IgM and IgG+M+A compared to normal control. 3. Between degenerative arthritis and rheumatoid arthritis group, no sigificant difference was noticed. 4. Rheumatoid arthritis group showed significant increase of IgM antibody level compared to normal control. 5. Female rheumatoid arthritis group showed significant increase of IgM level compared to female degenerative arthritis group. These findings suggested that the elevation of anti-type II collagen antibody titer is not specific for rheumatoid arthritis and related with general pathologies destroying articular cartilage. And it is suggested that anti-type II collagen antibody associated with rheumatoid arthritis is mainly IgM proportion, especially in female patients. So further investigation of anti-type II collagen antibody associated with rheumatoid arthritis is needed to target IgM antibody.
