There have been a few reports suggesting that the imune response to pulmonary tuberculosis provides the appropriate setting for the development of IgA nephropathy (IgAN). To define better the relation between pulmonary tuberculosis and IgAN, we evaluated the prevalence of pulmonary tuberculosis among 386 Korean patients with IgAN. Seventeen cases (4.4%) showed abnormal chest X-ray findings suggestive of pulmonary tuberculosis. Ten patients were male and seven were female. Only one case was a child. Urinary abnormalities were detected during the course of antituberculous medication in 11 patients, and after completion of chemotherapy in 2. Chest abnormalities were noted in the remaining 4 patient after IgAN had been diagnosed. Clinical diagnosis of tuberculosis was made mainly based on the chest X-ray findings, but sputum Acid-Fast Bacilli were detected in one patient and pulmonary granulomo was noted in 2. The patients presented various clinical manifestations such as gross hematuris (5 cases), nephrotic syndrome (5 cases), asymptomatic urinary abnormalities (4 cases) and pyuris (1 case) at time of biopsy. Histologic grading of the glomerular lesions was made with modified Meadow classification (1972): one had grade I lesion, 8 grade II, 5 GRADE III and 3 showed grade IV. Follow-up studies were made in 7 patients. Six showed resolution of urinary abnormalities after completion f antituberculous medication, while one pursued chronic renal failure 20 days after the onset. The above clinical and morphologic features suggest that pulmonary tuberculosis may be partly related to the occurrence of IgAN in some Korean patients.

Prognosis and biologic behavior of malignant ovarian tumors have been assessed by clinical staging, morphological grading and many other variables. Recently DNA ploidy measured by flow cytometry has been suggested as an additional important indicator of the tumor behavior and prognosis. The author measured DNA ploidy, S-phase fraction and DNA Index in 36 patients of epithelial ovarian tumors(17 were malignant, and 19 were borderline) by flow cytometric analysis of paraffin embedded tumor blocks. Comparing with FIGO stage, tumor grade, histologic type and others, the author investigated the clinical significance of the results of flow cytometric analysis. The results obtained as follows : (continue)

We report a case of Ael in a 44-year old woman. The patient s red cells were typed as 0 and her serum had both anti-A and anti-B, but the agglutination strength with Al cell was weaker (2+) than with B cell (4+) in her serum. Additional tests showed that the red cells were not agglutinated by anti-A,B and A antigen on patient s RBC was demonstrated by adsorption-elution test. Her saliva contained H but no A substance, and the ABO genotyping test identified her blood type as AO. We concluded that this was a case of blood type Ael with anti-A.

A 'circadian rhythm' is a self-sustained biological rhythm (cycle) that repeats itself approximately every 24 hours. Circadian rhythms are generated by an internal clock, or pacemaker, and persist even in the absence of environmental time cues, collectively termed 'zeitgebers.' Although organisms generate circadian rhythms internally, they are entrained by environmental stimuli, particularly the light-dark cycle. Measurement of the endogenous melatonin rhythm provides relatively reliable surrogate way of assessing the timing of the internal circadian clock. Also, core body temperature and cortisol can be used as markers of circadian rhythms. The sleep-wake cycle, body temperature, and melatonin rhythm have a stable internal phase relationship in humans and other diurnal species. They play an important role in controlling daily behavioral rhythms including task performance, blood pressure, and synthesis and secretion of several hormones. In this review, we address not only the properties, methods of measurement, and markers of circadian rhythms, but also the physiological and psychological importance of human circadian rhythms.

The molecular mechanisms that regulate glossal muscle cell cycle and terminal differentiation remain largely unknown. To determine which cyclins, cyclin dependent kinases (CDKs), cyclin dependent kinase inhibitors (CKIs) are important for glossal cell proliferation, we have examined expression of cyclins CDKs, CKIs during normal glossal muscle development in the rat. All cyclins, CDKs, and KIP/CIP family of CKIs were highly expressed during fetal glossal muscle development, then they decreased at different rates after birth. While the mRNAs of cyclin Dl, D3, E , A, and B decreased gradually in glossal muscle during all stages of development, the protein levels of these cyclins decreased differently in tongue during pre- and postnatal development. While the functionally active formed of cyclin Dl, cyclin D3 and E proteins were observed until 7 days after birth, cyclin A and B proteins were decreased more slowly. While the CDK4, CDK6, CDK2, cdc2, and proliferating cell nuclear antigen (PCNA) proteins were higllly present during fetal glossal muscle development and gradually decreased during postnatal development. Particularly, cdc2 levels decreased markedly after birth. Immunohistochemical data for PCNA was consistent with Western blotting data for PCNA temporally and spatially. The mRNA and protein levels of p21, p27, and p57 were high, then their levels changed differently during glossal development. While the mRNA levels of p21 and p57 decreased gradually, the mRNA level of p27 did not change during glossal development. While the protein levels of p21 and p57 in tongue decreased markedly after birth, the protein levels of p27 increased slightly after birth, then decreased at adulthood. These findings suggest that the all cyclins and CDKs observed are involved in glossal muscle cell cycle, and reduction of cyclins and CDKs and induction of p21 are associated with the withdrawal of glossal muscle cell cycle after birth.

OBJECTIVES: Mild cognitive impairment(MCI) and dementia of Alzheimer's type(AD) are characterized by progressive decline of cognitive abilities and a wide range of neuropsychiatric symptoms like depression. Among various diagnostic tools of AD, many studies showed that elevated levels of serum total homocysteine are associated with increased risk of developing Alzheimer's disease, depression and other neuropsychiatric disorders. We investigated whether elevated homocysteine concentrations are associated with depressive symptoms in MCI and AD. METHODS: A total of 86 patients diagnosed with MCI or AD participated. Total serum homocysteine levels in fasting blood samples were measured. We examined cognitive symptoms by MMSE-KC, Global Deterioration Scale(GDS), Clinical dementia rating(CDR) and depressive symptoms by Korean version of Geriatric Depression Scale(K-GDS). RESULTS: The total serum homocysteine levels were significantly higher in MCI with depression than in MCI without depression. There was no significant difference in the mean homocysteine levels between AD patients with depression and AD patients without depression. The total homocysteine levels showed a negative correlation with MMSE-KC and a positive correlation with CDR, GDS. CONCLUSIONS: These findings suggest that elevated homocysteine level is a risk factor for the decline of cognitive function and depression. We found a significant relationship between elevated serum homocysteine level and depressive symptoms in MCI. But our study had several limitations, thus more research is needed to confirm this finding.
