The gene ftsH encodes a membrane-bound and ATP-dependent protease that is involved in a variety of cellular functions including heat-shock and stress response. Streptococcus pneumoniae DNA encompassing most part of the ftsH gene was cloned in Escherichia coli and sequenced. Due to the unsuccessful cloning as seen in other pneumococcal promoters, the 5'-end of the gene including the upstream promoter region was amplified by inverse polymerase chain reaction and then sequenced by cyclic sequencing. The amino acid sequence that is deduced from the 1,959 bp-long ftsH gene is very similar to FtsH of several gram-positive bacteria and E. coli within the region responsible for the AAA (ATPase associated with diverse cellular activities) function. Except for the N-terminal domain that contains a short extracellular region between two mernbrane-spanning segments, pneumococcal FtsH shows striking sequence similarity to that of a closely related species Lactococcus lactis within the conserved cytoplasmic domain where two ATP-binding motifs, the AAA Signature motif, and a zinc-binding motif are found.

This study presents a case of a patient who experienced sudden death due to fatal nitrite poisoning in the medical setting. It also highlights the pivotal role of postmortem examination in enhancing quality assurance in clinical medicine, as well as in providing resolutions for medicolegal disputes to all pertinent stakeholders, regarding the patient’s death. The patient was found dead during admission after orthopedic surgery. The death certificate was issued by the clinician attributing the cause of death to respiratory failure due to pulmonary embolism. This medical certification of death instigated medicolegal disputes, resulting in allegations of medical negligence or malpractice. Subsequently, a death investigation was initiated, and a postmortem examination confirmed nitrite poisoning as the cause of death. This medical evidence obtained from the autopsy could provide clarity in resolving medicolegal disputes surrounding the patient’s unexpected death in a medical setting. Moreover, a comprehensive review of all information obtained through a death investigation could offer valuable insights even for clinicians, as well as for patient’s family and other stakeholders. This includes guidance on certifying the cause of death based on varying levels of medical evidence and implementing preventive measures to enhance patient safety and mitigate the occurrence of unexpected death in the medical setting.

Tuberculosis of the thyroid gland is extremely rare with few cases reported in recent years. Tuberculosis may involve the thyroid gland in two main forms. The more common of theses is miliary spread to the thyroid as part of generalized dissemination and less commonly focal or caseous tuberculosis of the thyroid may occur, presenting as a nodule, as a thyroiditis, as a abscess, or as carcinoma like.We experienced two cases of tuberculosis of the thyroid gland presenting with palpable thyroid nodule in 26 year-old female and 65 year-old female patients. They have been clinically and biochemically euthyroid and their thyroid scans demonstrated a cold nodule at right thyroid gland. We found no evidence of tuberculosis elsewhere. The goiter was removed surgically and confirmed to be tuberculosis. They were medicated antituberculous agents after operation and followed up regulary out patient department.We report the cases of two patients with tuberculosis involving thyroid with reviews of literature.

BACKGROUND: Hypertension is the major risk factor for cardiovascular disease. The increased left ventricular mass has been recognized as an independent predictor of morbidity and mortality in hypertensive patients. The assessment of the regression of left ventricular(LV) mass after antihypertensive therapy offers prognostic information. 2D echocardiography has proved a sensitive tool for the detection of the change of LV mass. METHOD: LV mass and LV mass index were measured by area-length method of 2D echocardiography in 26 hypertensive patients and 10 normal control to evaluate the effect of betablocker(group I, n=16) and angiotensin converting enzyme(ACE) inhibitor(group II, n=10) on the regression of LV mass. RESULT: There was a significant increase of LV mass and LV mass index in the hypertensive patients(199.0+/-37.7gm, 119.2+/-21.2gm/m2) compaired to the control(129.7+/-11.7gm, 87.4+/-8.8gm/m2)(p<0.01, p<0.01). After 13.1 week treatment, LV mass was significantly decreased in group I(200.9+/-35.3gm vs 164.7+/-25.4gm)(p<0.01) and group II(195.9+/-43.3gm vs 152.4+/-27.1gm)(p<0.01). The LV mass index was also significantly decreased in group I(120.3+/-20.7gm/m2 vs 98.8+/-15.5gm/m2)(p<0.01) and group II(117.5+/-22.9gm/m2 vs 91.5+/-13.6gm/m2)(p<0.01). CONCLUSION: This results showed that LV mass can be reduced in hypertensive patients who receive beta blocker and ACE inhibitor. The effect of antihypertensive therapy on LV mass should be considered in treatment of the hypertensive patients who had hypertrophied LV.

The study was undertaken to evaluate the effect of major blood components on the CT number. The CT numbers according to the various levels of hematocrit, total protein and cholesterol were checked and analysed by the dilution of pack cell, plasma and 184 complete blood cell count samples under same scanning conditions. In case of normal protein and cholesterol level(33 samples), the CT number was increased about 5.5 hounsfield unit according to 10% increase of hematocrit level: and In case of normal hematocrit and cholesterol level(39 samles), the CT number was increased about 3.5 hounsfield unit according to 1gm% increase of protein level. CT number changes were not predictable according to the changes of cholesterol level(34 samples). From these results, we concluded that major blood components should be considered in the CT number analysis of tissue.

Many studies have reported structural or functional brain changes in patients with alcohol-dependence (ADPs). However, there has been an insufficient number of studies that were able to identify functional changes along with structural abnormalities in ADPs. Since neuronal cell death can lead to abnormal brain function, a multimodal approach combined with structural and functional studies is necessary to understand definitive neural mechanisms. Here, we explored regional difference in cortical thickness and their impact on functional connection along with clinical relevance. Fifteen male ADPs who have been diagnosed by the Diagnostic and Statistical Manual of Mental Disorders 5 (DSM-5) underwent highresolution T1 and resting-state functional magnetic resonance imaging (MRI) scans together with 15 male healthy controls (HCs). The acquired MRI data were post-processed using the Computational Anatomy Toolbox (CAT 12) and CONN-fMRI functional connectivity (FC) toolbox with Statistical Parametric Mapping (SPM 12). When compared with male HCs, the male ADPs showed significantly reduced cortical thickness in the left postcentral gyrus (PoCG), an area responsible for altered resting-state FC patterns in male ADPs. Statistically higher FCs in PoCG-cerebellum (Cb) and lower FCs in PoCG-supplementary motor area (SMA) were observed in male ADPs. In particular, the FCs with PoCG-Cb positively correlated with alcohol use disorders identification test (AUDIT) scores in male ADPs. Our findings suggest that the association of brain structural abnormalities and FC changes could be a characteristic difference in male ADPs. These findings can be useful in understanding the neural mechanisms associated with anatomical, functional and clinical features of individuals with alcoholism

As a part of plan to construct a multifunctional hospital information system, We planned to develop a chemotherapy order system. First, a software developing team was established which is composed of hematooncology staffs, special pharmacists and programmer who are responsible for OCS. We set up an outline of this system after collecting various kinds of sources such as foreign examples, gathered protocol that are used for chemotherapy, and organized these protocol in programming the chemotherapy order system. This project is expected to provide accurate prescription, to shorten the time to prepare prescription, to standardize the protocol of chemotherapy within the medical center, to manage an effective dispensing schedule and to be used as a source for education and research.
