There are various complex formations between immunoglobulin and serum enzymes in the body. Of these, LD-Immunoglobulin complex is most common. It has reported that LD-IgG or LD-IgA complex existed in the serum of healthy person or many patients who have various clinical disorders. The clinical significance of complexes is not known, but it results in the increase of total LD activity and interference to the LD isoenzyme electrophoresis interpretation due to its anomalous pattern. We have reported a case of LD-Immunoglobulin complex in AILD(Angioimmunoblastic lymphadenopathy with dysproteinemia) with reference. The patient was admitted with fever, chills and cervical LN enlargement, in LN biopsy, diagnosed AILD, and during treatment expired by sepsis. Since admission, serum total LD activities were increased and serum LD isoenzyme EP showed that LD3-5 fractions was not separated in broad single band. Its pattern was due to LD-immunoglobulin complex, LD-bound immunoglobulin was IgG ,lamda. For the identification of immunoglobulin, we at first did serum protein immunoelectrophoresis. then stained the plate with tetrazolium dye for LD activity.

The authors have experienced 3 Rho(D) negative siblings from Rho(D) positive parents. ABO grouping and typing were carried out because the parents wanted their and children's blood types. On the five major Rh antigen(D, C, c, E, e) testing, the phenotypes of the both parents were CcDe, and those of their 3 siblings were cde. We can suspect the possible genotypes on the basis of the frequencies in Korean, both parents are CDe/cde and their 2 daughters and one son are cde/cde.

For the morphological analysis of DMBA (9,10-diemethyl-1,2-benzanthracene) induced tumor, thirty Sprague-Dawley rats were received 0.1 ml of a 2% paraffin solution of DMBA into the knee joint cavity, which was repeated three times at an interval of 4 weeks. The induced tumor masses were removed at the 12th week after the first injection. Histological and histochemical examinations (H & E, PAS, alcian blue, Van Gieson, prussian blue, reticulin, PTAH stain) and enzyme histochemical examinations (acid phosphatase, alkaline phosphatase, alpha-naphthyl acetate esterase) were performed. The results were as follows: 1) By the 12th week after the first injection of DMBA, the tumor incidence rate was 20 percent. 2) On histological and histochemical examination, most of the induced tumor disclosed the features of the fibrous histiocytoma originating from mesenchymal cells, and the remains sweat gland adenoma and adenocarcinoma originating from epithelial cells. 3) On enzyme histochemical examination, most of the mesenchymal cell-derived tumor cells showed positive reactions for acid phosphatase and alpha-naphthyl acetate esterase, which were similar characteristic features of enzyme stains as shown in the component cells of fibrous histiocytoma.

BACKGROUND: Cardiac troponin T (cTnT) is a new serological marker for use as a diagnostic toots for acute myocardial infarction (AMI). This study was designed to evaluate tee diagnostic efficiency of troponin T in AMI. METHODS: We determined the reference range of troponin T in 20 healthy adults without previous cardiovascular diseases and chest pain. We evaluated troponin-T, CK, LD, AST and CK-MB in serum of 13 AMI and 5 angina pectoris patients. The patients were arrived at the hospital within 3 hours after onset of (most recent) acute symptoms. Samples were drawn individually at the times of 0, 1, 3, 7, 18 and 24 hours after admission and continued at 6-h intervals for 2 days and 24-h intervals fort 2 weeks. Troponin T was determined by an enzyme-linked immuno-sorbent assay (one step sandwich assay) on an ES-300 analyzer. RESULTS: We found that serum troponin-T concentrations in healthy control adults were below 0.07microgram/L. The peak level of troponin-T concentration of patients with AMI was 22.0microgram/L, mean value, at 7 hours after admission and showed 110 times its discrimination limit value (0.2microgram/L). CK-MB value was normalized within 3 days after admission, but cTnT value remained high above its discrimination limit value until 2 weeks after admission during this study. CONCLUSIONS: The data indicate that the measurement of serum cTnT improves efficiency of serological testings of AMI as compared with conventionally used cardiac enzymes.

An immunohistochemical study on the tissue localization of human chorionic gonadotropin (HCG), human placental lactogen (HPL), and human pregnancy specific bata-1 glycoprotein (SP-1) in the non-neoplastic (5 incomplete abortion, 5 ectopic pregnancy) and neoplastic (hydatidiform mole 3 cases, 5 ectopic pregnancy) and neoplastic (hydatidiform mole 3 cases, choriocarcinoma 2 cases) gestational status, and germ cell tumors of the ovary (dysgerminoma 2 cases, immature teratoma 1 case) and the testis (seminoma 2 cases, endodermal sinus tumor 1 case) by means of sensitive peroxidase-antiperoxidase method. The results were as follows. 1) Cytoplasmic HCG, HPL, and SP-1 were readily identified in syncytiotrophoblasts of chorionic villi of the incomplete abortion and ectopic pregnancy, as moderate to strong positive reactions. In the cytoplasm of the neoplastic syncytiotrophblasts of hydatidiform mole and choriocarcinoma, positive reactions were stronger than in non-neoplastic syncytiotrophblasts. but the cytotrophoblasts and villous stromal cells showed negative reactions to these hormones. 2) All of the tumor cells of dysgerminoma and immature teratoma of the ovary, and seminoma and endodermal sinus tumor of the testis showed negative reactions to HCG, HPL, and SP-1. According to these results, HCG, HPL, and SP-1 are specifically synthesized and secreted by normal or neoplastic syncytiotrophoblasts Malignant tumors originated from other cells or tissues than trophoblastic cells show elevated serum concentration of these hormones are only evident in the presence of syncytiotrophoblastic giant cells among the tumor cells.
