In a small island community with a population of less than 100 residents, nine persons died and five experienced severe illnesses during the period from November 1986 to May 1988. Their initial symptoms were sore throat and fever. Renal failure and hepatitis developed within one week after the onset. Oral mucosal ulcer developed in some cases. After one week, progressive respiratory failure and dyspnea developed evidently and severe respiratory distress and hypoxia preceded those fatal cases. Chest X-ray findings revealed bilateral diffuse multiple cystic lesion with occasional multiple large emphysematous bullae. Based on these features paraquat poisoning was diagnosed and route of poisoning was investigated. In three sources of drinking water, trace amount of paraquat was detected in November 1988, six months after the incidence of recent fatal case. In November 1988, soybean sauces and soybean pastes from 12 households were found contaminated with high concentration of paraquat, the cause could not be identified. The possibility of the contamination of drinking water as the cause of this mass poisoning has been suggested.

This paper presents the effective data processing system of a transportable meteorological radar(DWSR-200x). Transportable meteorological radar is useful as it can be moved to target area for special purpose. First of all, to use this radar effectively, it is desirable that the data transmitting should be taken place between the radar system and the data center located in a distance. From this raw data we can analyze the property of atmosphere, as well as sore and display the demanded shape of users. In this paper, we make use of wireless LAN that communicates the data between the radar system and the information center.

Reduction cranioplasty is one of the treatment modality among many treatment options for macrocephaly with hydrocephalus. The most previous techniques of reduction cranioplasty have some disadvantages such as difficult airway maintenance, pressure sore due to modified prone position, severe venous infarct due to obstruction of venous blood flow and large amount of bleeding from the dissection of superior sagittal sinus to obtain bone fragment needed. A 28-month-old girl had extreme macrocephaly. She couldn't control head rotation and keep sitting position. The operation was performed at supine position with adequate exposure of entire calvarium and the hinge was made in occipital bone fragment that covered posterior part of superior sagittal sinus. Bleeding volume and the other complications were decreased and acceptable reduction was achieved with this method.

The term laryngopharyngeal reflux (LPR) refers to the backflow of food or stomach acid back up into the larynx (the voice box) or the pharynx (the throat). Esophagopharyngeal reflux is suggested as an etiologic factor in laryngeal disease. To examine a possible esophageal basis for laryngopharyngeal symptoms, we studied 48 patients with persistent laryngopharyngeal symptoms, and 12 relative control subjects. Patients were evaluated for cervical symptoms by questionnaire and underwent gastrofiberoscopy, fiberoptic laryngoscopy, esophageal manometry and 24-hour ambulatory double-probe pH monitoring. We found LPR in fourteen out of 48 patients with cervical symptoms (29%). The LPR group consisted of nine men and five women. The symptoms that LPR patients complained were throat lump sensation, hoareness, sore throat, throat clearing, chronic coughing and dysphagia in order of frequency, and they were not different significantly from non-LPR patients. The laryngoscopic findings in LPR patients were posterior erythema, laryngeal edema and diffuse erythema, and there was also no significant difference between LPR group and non-LPR group. There was statistically significant correlation between LPR and gastroesophageal reflux (GER). We concluded that there is no pathognomonic symptoms or laryngoscopic findings in diagnosis of LPR, and 24-hour ambulatory double-probe pH monitoring is an essential diagnostic tool in LPR.

The flowers of Buddleja officinalis are used to treat sore and damaged eyes, a condition which is similar to skin wounds. However, whether it has any protective effect on oxidative DNA damage and cell death induced by hydroxyl radical remains unclear. In this study, we evaluated the protective effects of the extracts against oxidative DNA and cell damage caused by hydroxyl radical. DPPH radical, hydroxyl radical, hydrogen peroxide and intracellular ROS scavenging assay, and $Fe^{2+}$ chelating assay were used to evaluate the antioxidant properties. phi X 174 RF I plasmid DNA and intracellular DNA migration assay were used to evaluate the protective effect against oxidative DNA damage. Lastly, MTT assay and lipid peroxidation assay were used to evaluate the protective effect against oxidative cell damage. It was found to prevent intracellular DNA and the normal cells from oxidative damage caused by hydroxyl radical via antioxidant activities. These results suggest that Buddleja officinalis may exert the inhibitory effect on ROS-induced carcinogenesis by blocking oxidative DNA damage and cell death.

Nowadays, COVID-19 infections are influencing our daily lives which have spread globally. The major symptoms' of COVID-19 are dry cough, sore throat, and fever which in turn to critical complications like multi organs failure, acute respiratory distress syndrome, etc. Therefore, to hinder the spread of COVID-19, a Computerized Doughty Predictor Framework (CDPF) is developed to yield benefits in monitoring the progression of disease from Chest CT images which will reduce the mortality rates significantly. The proposed framework CDPF employs Convolutional Neural Network (CNN) as a feature extractor to extract the features from CT images. Subsequently, the extracted features are fed into the Adaptive Dragonfly Algorithm (ADA) to extract the most significant features which will smoothly drive the diagnosing of the COVID and Non-COVID cases with the support of Doughty Learners (DL). This paper uses the publicly available SARS-CoV-2 and Github COVID CT dataset which contains 2482 and 812 CT images with two class labels COVID⁺ and COVI^-. The performance of CDPF is evaluated against existing state of art approaches, which shows the superiority of CDPF with the diagnosis accuracy of about 99.76%.
