A Study on glutamic pyruvic and oxaloacetic transaminase of different organs(e.g intestine, seminal vesicle, reticular tissue, uterus, ovary, testes) in Ascaris lumbricoides suis have been investigated. The activity of transaminase were determined on the whole homogenates and subcellular fractions separated by differential centrifugation. The activity of glutamic pyruvic and oxaloacetic were assayed by colorimetric method of Reitman-Frankel. The results were obtained as follows: About ninty percent of the glutamic pyruvic and oxaloacetic transaminase in different organs was found to be localized in the supernatant fraction with the separation of differential centrifugation. And it was found that ten percent of glutamic pyruvic and oxaloacetic transaminase exists in the mitochondrial fraction. The specific activity of glutamic oxaloacetic transnaminase in different organs was relatively higher than the glutamic pyruvic transaminase activity.

Journal of Preventive Medicine and Public Health 2021;54(2):96-102
Objectives:
Sarcopenia is a common disease in the elderly population that causes disability, poor quality of life, and a high risk of death. In the current study, we conducted a meta-analysis to report basic knowledge about the prevalence of sarcopenia in the elderly in Korea.
Methods:
We searched for articles in the MEDLINE, Cochrane Library, Embase, and Scopus databases published until December 28, 2020. Studies investigating the prevalence of sarcopenia in elderly Koreans aged ≥65 years were included. The methodological quality of the studies was evaluated using the Newcastle-Ottawa scale. Publication bias was evaluated using the Egger test and funnel plots.
Results:
In total, 3 studies and 2922 patients were included in the meta-analysis. All 3 studies used the European Working Group on Sarcopenia in Older People criteria for the diagnosis of sarcopenia. The total prevalence of sarcopenia was 13.1-14.9% in elderly men and 11.4% in elderly women.
Conclusions
This meta-analysis is the first to estimate the pooled prevalence of sarcopenia in elderly Koreans, and its findings suggest that sarcopenia is common in this population. Therefore, attention should be paid to the prevention and control of sarcopenia.

Spinal pain is a common patient complaint in clinical practice. Conservative treatment methods include oral medication, physical therapy, injections, and spinal orthoses. The clinical application of orthoses is debated because of potential complications associated with long-term use, such as muscle weakness and joint contracture. We reviewed the orthoses most frequently used to manage spinal pain. We review the use of soft cervical and Philadelphia collars, lumbosacral corsets, and thoracolumbosacral orthosis to manage spinal pain. Spinal orthoses can help reduce pain by protecting the muscles and joints of the injured spinal region, preventing or correcting malformations, and limiting trunk flexion, extension, lateral flexion, and rotation. The short-term use of spinal orthoses is known to improve pain and disability during the treatment period without significant adverse effects. Spinal orthoses are expected to alleviate pain and improve patients’ lifestyle.

A narrative review was conducted of machine learning applications and research in the field of stroke rehabilitation. The machine learning models commonly used in medical research include random forest, logistic regression, and deep neural networks. Convolutional neural networks (CNNs), a type of deep neural network, are typically used for image analysis.Machine learning has been used in stroke rehabilitation to predict recovery of motor function using a large amount of clinical data as input. Recent studies on predicting motor function have trained CNN models using magnetic resonance images as input data together with clinical data to increase the accuracy of motor function prediction models. Additionally, a model interpreting videofluoroscopic swallowing studies was developed and investigated. In the future, we anticipate that machine learning will be actively used to treat stroke patients, such as predicting the occurrence of depression and the recovery of language, cognitive, and sensory function, as well as prescribing appropriate rehabilitation treatments.

Purpose:
The effect of prehabilitation in patients with frailty undergoing colorectal cancer surgery remains controversial. This meta-analysis aimed to assess the impact of prehabilitation before colorectal surgery on the functional outcomes and postoperative complications in patients with frailty undergoing colorectal cancer surgery.
Methods:
PubMed, EMBASE, Cochrane Library, and Scopus databases were searched for articles published up to November 9, 2022. We included randomized and non-randomized trials in which the effects of prehabilitation in patients with frailty undergoing colorectal cancer surgery were investigated against a control group. Data extracted for our metaanalysis included the 6-minute walk test (6MWT), postoperative incidence of complications (Clavien-Dindo classification ≥IIIa), comprehensive complication index (CCI), and length of stay (LOS) in the hospital.
Results:
Compared with the control group, we found a significant improvement in the incidence of postoperative complications and shorter LOS in the hospital in the prehabilitation group. However, the 6MWT and CCI results showed no significant differences between the 2 groups.
Conclusion
Prehabilitation in patients with frailty who underwent colorectal cancer surgery improved the incidence of postoperative complications and LOS in the hospital. Hence, clinicians should consider conducting or recommending prehabilitation exercises prior to colorectal cancer surgery in patients with frailty.

Disseminated mucormycosis is a rare fungal infectious disease with a high mortality rate and is infrequently diagnosed ante mortem. It is most frequently seen in immunocompromised hosts such as diabetes mellitus, hematologic malignancies, or in the long-term use of steroids or chemotherapeutic agents. Tissue invasion by the hyphae of mucormycosis must be seen microscopically to establish the diagnosis. Treatment consists of correction of the predisposing condition, surgical debridement, and amphotericin-B therapy. A 35-year-old man was admitted through the emergency room due to fever and the right flank pain. He had received an allogenic bone marrow transplantation eight months ago and had been medicated with prednisolone and cyclosporine since the procedure. He was diagnosed with disseminated mucormycosis that involved the spleen, right kidney, and right lung. He is being successfully treated with amphotericin B, flucytosine, and liposomal amphotericin B.

Malignant hyperthermia is an inherited disorder of skeletal muscle, characterized by temperature elevation, muscle destruction, muscle rigidity and high oxygen consumption. It is triggered by anesthetic agents, usually potent inhalation anesthetics and succinylcholine. It is fatal in the majority of cases unless early diagnosis and treatment are performed. We experienced one case of malignant hyperthermia incidentally. She had post burn scar contracture on anterior chest and abdomen and local flap was prepared for releasing scar contracture under general anesthesia. Approximately 3 hours after induction, tachycardia developed followed by severe arrhythmia with unstable blood pressure, temperature elevation and cyanosis. Anesthesia was stopped immediately and aggressive emergency management was performed with Dantrolene. About 4 hours after induction, the patient was recovered to normal state with intensive care.

BACKGROUND: Pulmonary complications following bonemarrow transplantation(BMT) are common and associated with a high mortality rate, We investigated the yield, safety, and impact of fiberoptic bronchoscopy(FOB) for diagnosis of postBMT pneumoniae. METHODS: From May 1997 to April 2000, 56 FOBs were performed in 52 post BMT patients for clinical pneumoniae. BMT patients with repiratory symptoms and/or pulmonary infiltrates had a thoracic HRCT(high resolution computed tomography) and bronchoscopic examination including BAL(bronchoalveolar lavage), TBLB(transbronchial lung biopsy), PSB(protected specimen brush). RESULTS: The characteristics of the subjects were as follows:37 males, 15 females, mean age of 31.3 years(17-45), 35 sibling donor allogenic BMTs, 15 nonrelated donor allogenic BMTs, and 2 autologous BMTs. Fiftynine percent of FOBs (33 FOBs, 31 patients) were diagnostic. Isolated pathogens included the following:12 cytomegalovirus(CMV) (21.4%), 7 pneumocystis carinii(PC) (12.5%), 11 CMV with PC (19.6%), 2 Mycobacaterium tuberculosis (3.6%), and 1 streptococcus (1.8%). Most of the radiographic findings were diffuse interstitial lesions. CMV pneumoniae had mainly diffuse interstitial nodular lesion, and PC pneumoniae had diffuse, interstitial ground glass opacity(GGO). When CMV was accompanied by PC, a combined pattern of nodular and GGO was present. Of the 56 cases(23.2%), 13 died of CMV pneumoniae(n=2), PCP(n=2), mixed infection with CMV and PC(n=3), underlying GVHD(n=1), underlying leukemia progression(n=1), or respiratory failure of unknown origin(n=4). There was no major complication by bronchoscopy. Only 3 cases developed minor bleedig and 1 episode temporary hypoxemia. CONCLUSION: Based on our findings, CMV and PC are the major causes of postBMT pneumoniae. In addition, BAL can be considered a safe and accurate procedure for the evaluation of pulmonary complications after BMT.
