Intercellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1) are weakly expressed in normal glomerular cells and vascular endothelial cells, but not in tubules. Granzyme B is a cytotoxic granule present in activated cytotoxic T cells and natural killer cells. To determine the effect of ICAM-1 and VCAM-1 expression and granzyme B-positive cells on histologic grade of rejection, we performed the immunohistochemical study on 19 renal biopsy specimens and one nephrectomy specimen from 14 patients with acute renal allograft rejection using monoclonal antibodies against theses proteins. According to severity of rejection based on Banff classification, three biopsies were classified as borderline, 4 grade I, 12 grade II, and 1 grade III. In all the cases with acute rejection, ICAM-1 and VCAM-1 were expressed in the tubular epithelial cells. The numerical score of ICAM-1 in the tubular epithelial cells was 1.0 in borderline cases, 1.3 0.4 in grade I cases, 2.2 0.8 in grade II cases, and 3.0 in grade III case. The staining intensity of ICAM-1 in the tubular epithelial cells was increased in accordance with histologic rejection grade (P<0.05). The staining intensity of ICAM-1 and VCAM-1 in the renal tubular epithelial cells was increased in accordance with the number of T lymphocytes in the renal parenchyme (r=0.46; P<0.05, r=0.61; P<0.01). The number of granzyme B-positive cells was 6.4 1.6/HPF in borderline cases, 8.1 2.5 in grade I cases, 19.6 11.7 in grade II cases, and 53 in grade III case. The number of T lymphocytes and granzyme B-positive cells was also increased in accordance with histologic rejection grade (P<0.05). These results suggest that ICAM-1 and granzyme B-positive cells may play an important role in the induction of renal allograft rejection and that the grading of severity of these parameters may be useful to predict the prognosis of renal allograft.

The purpose of this study were to find out the practical way to enlarged child-raising knowledge and to enhance their satisfaction with out-patient care by evaluating how effectively the education is done by nurses for mothers with ill-child and how their satisfaction with out-patient care changed. This study was designed as a Nonequivalent Control Group study. The subjects studied were consisted of the experimental and control group. Each consisted of 50 mothers with ill-child in pediatric department at one university hospital in Seoul. The period of this study is from May 20, 1996 to June 28, 1996. The first data were collected fro both of experimental and control groups in which mothers with ill-child come to the hospital for the first time. After this being done, the experimental group had been educated by the planned program and then the second data were collected from them. On the contrary, as for the control group, there had been no education and the second data were collected on the same method. The data analysis was done by SPSS program. The results of this study are as follow, 1. The child-raising knowledge level of mothers with education was higher than that of with no education.(t=18.84, df=49, p=0.000) 2. The satisfaction with out-patient care level of mothers with education was higher than that of no education.(t=10.51, df=49, p=0.000) Based on these results, I suggest as follow, 1. The research on the patients and their family should be made not only in pediatric department, but in every out-patient department. 2. For more effective education, it is required for all out-patient nurses to research the education demand of patients and their family. 3. To increase the effect of education, there must be the consultation room in out-patient department. 4. The meetings with the mothers with ill-child of the same illness have to be established and periodical education must be executed. 5. Audio-visual education programs like video tapes are needed to make use of waiting time for the medical treatment. 6. On-line consulting program are needed.

An association of low total cholesterol in blood with psychiatric diseases and suicidal behavior has been suggested. As part of an attempt to further explore this relationship, we examine first, whether serum cholesterol levels in psychiatric patients with suicidal attempt would be lower than in non-suicidal psychiatric inpatients or normal controls, second, whether such significant difference of cholesterol levels would be present when the diagnostic groups are analyzed separately, third whether low cholesterol level would be associated with a history of serious suicidal attempts, and finally, whether low cholesterol level in suicide attempters is as state or a trait marker. We determined the serum cholesterol levels in 231 patients admitted to an emergency room following an suicidal attempt, in the same numbers of age-, sex- and diagnosis-matched non-suicidal psychiatric controls, and in the same numbers of age-, sex matched normal controls. The seriousness of an attempt was divided into 5 grades according to the degree of the resulting medical injury. Total cholesterol levels in suicide attempters were significantly lower compared with both psychiatric and normal controls, when sex, age, and nutritional status(i.e., body mass index) were controlled for. This significant relationship was observed in major depressive disorders and personality disorders, but not in schizophrenia and bipolar type I disorders. The severity of suicide by a lowering of blood cholesterol was related to the magnitude of the cholesterol reduction. After treatment of their psychiatric ailments, the cholesterol levels in suicide attempters were significantly increased. This result suggests that low cholesterol level in psychiatric patients might be a potential biological marker of suicide risk. It is hypothesized that low cholesterol levels is associated with the suicide by modifying the serotonin metabolism, the production of interleukin-2 and melatonin metabolism in psychiatric patients.

In epilepsy-aphasia spectrum (EAS) disorders, mutations in the glutamate receptor ionotropic N-methyl-D-aspartate type subunit 2A (GRIN2A) have become important for screening the disease. Research into the phenotypic variability of several types of neurologic impairment involving these mutations is in progress. However, the non-neurological problems related to these mutations are poorly understood. EAS disorders usually have epileptic, cognitive, or behavioral manifestations. In this case report, we present a female patient with epilepsy, delay in expressive language and social development, and intellectual disability with low intelligence quotient and memory quotient, but normal motor development. Through genetic analysis, she was found to have a missense and a nonsense mutation in GRIN2A (c.1770A>C; p.Lys509Asn and c.3187G>T; p.Glu1063*, respectively) and we consider the nonsense mutation as ‘pathogenic variant’. She was also discovered to have congenital hypothyroidism, growth hormone deficiency and Rathke’s cleft cyst in the brain, which were previously unknown features of GRIN2A mutation. Our findings should widen understanding of the spectrum of GRIN2A phenotypes, and emphasize the need for more research into the association between GRIN2A mutations and non-neurologic clinical presentations.

Antiphospholipid syndrome (APS) is a noninflammatory autoimmune disorder characterized by the association of arterial and/or venous thrombosis, recurrent fetal loss and elevated titres of antiphospholipid antibodies, namely lupus anticoagulant (LAC) and/or anticardiolipin antibodies (aCL). It can either occur as a free-standing condition (primary APS) or be associated with another autoimmune disease (secondary APS), mainly systemic lupus erythematosus. The precise pathogenesis of thrombosis in APS in unknown. For children with unexplainable venous or arterial thrombosis, APS should be considered. The diagnosis of APS in children requires a clinical event including venous or arterial thrombosis or immune thrombocytopenia and a laboratory abnormality including positive LAC test or positive aCL antibody test, moderate or high titer IgG. The laboratory abnormality should persist for at least 2 months. We report a 7-year-old girl who had pulmonary embolism and multiple arterial thrombosis caused by primary APS. The laboratory abnormality was positive LAC and beta2-glycoprotein I. She was treated successfully with low molecualr weight heparin (LMWH). After recovery, she was continuously treated with subcutaneous LMWH for another 3 months and switched to oral warfarin. She was symptom-free through 3 years of follow-up.

Objectives:
The purpose of this study was to identify the effectiveness of COVID-19 vaccinations on deaths of the COVID-19 cases in some elderly long-term care facilities (LTCF) in Gwangju Metropolitan City.
Methods:
The study subjects were 659 COVID-19 cases in residents of 7 elderly LTCF, Gwangju, from 21 Dec. 2021 to 28 Jan. 2022. The used variables were confirmed dates for COVID-19, demographic characteristics, co-morbidities, presentation of symptoms, death and vaccination related characteristics including type of vaccine, doses and dates. Vaccination status were classified as not vaccinated, partially and fully vaccinated. The associations of vaccination status and deaths of COVID-19 cases were tested by chi-square test and multiple logistic regression analysis.
Results:
The rates of not vaccinated, partially vaccinated and fully vaccinated were 19.4%, 10.2% and 70.4%, respectively. The mortality rate of the cases was 6.4%.The death rate by vaccination status was 16.4% in not vaccinated, 15.4% in partially vaccinated and 2.6% in fully vaccinated, showing a statistically significant difference. The adjusted odds ratios (ORs) (95% confidence intervals, CIs) of death compared to fully vaccinated were 7.64 (3.87-16.34) in non-vaccinated, and 6.97 (3.44-14.14) in partially vaccinated.
Conclusions
COVID-19 vaccination seems to work effectively in preventing deaths of COVID-19 cases of elderly LTCF residents. This finding support that fully vaccinations in high risk group such as elderly LTCF residents is very important for one of strategies of COVID-19 management.

Glomerulosclerosis represents a pathological hallmark of progressive glomerular injury. Mesangial cell proliferation and accumulation of extracellular matrix (ECM) proteins in the mesangial area frequently precede the formation of glomerulosclerosis. To understand the role of platelet-derived growth factor (PDGF) and ECM in the development of glomerulosclerosis, we examined the expression of type IV collagen, laminin, fibronectin, and PDGF in 45 renal biopsies diagnosed with IgA nephropathy (IgAN) using a standard peroxidase antiperoxidase (PAP) technique. Normal control specimens were obtained from four nephrectomy specimens diagnosed with renal cell carcinoma. As compared with normal controls, type IV collagen increased in 68%, fibronectin in 73%, laminin in 51%, and PDGF in 36% of patients with IgA nephropathy. The staining intensity of PDGF, type IV collagen, and fibronectin increased significantly in cases with moderate to severe mesangial cell proliferation than cases without. In the areas of glomerulosclerosis, the staining intensity of type IV collagen, laminin, and PDGF decreased, whereas that of fibronectin increased. These results suggest that mesangial cell proliferation in relation to increased PDGF expression in IgAN could stimulate the expression of type IV collagen, laminin and fibronectin leading to mesangial expansion. They also suggest that ECM decreased in advanced glomerulosclerosis. Deposition of fibronectin, which originates mainly from the blood stream, increases during the course of progressive glomerulosclerosis, whereas other ECM components decrease in advanced glomeruloslresosis.
