The effects of cortisone administration and whole body irradiation by X-ray upon mesenteric mast cells of intact and adrenalectomized albino rats were studied. In intact rats, the administration of cortisone (50mg./kg) and whole body irradiation by X-ray (800r) caused severe degranulation and disruption of mesenteric mast cells within 24 hours. However their degranulation and disrupting effects upon mesenteric mast cells were markedly inhibited after the removal of the adrenal gland. Although the adrenalectomy alone hardly caused these morphological changes of mesenteric mast cells of the albino rats. According to this experiment it is fairly clear that the effects of cortisone and whole body X-ray irradiation inducing degranulation and disruption of mesenteric mast cells of the albino rats, were not direct phenomena but they indirectly affected the mesenteric mast cells through some special mechanism mediated by the adrenal gland.

We examined whether the abnormal EEG state by NMDA receptor blocker MK-801 can be reversed by typical and atypical antipsychotics differentially by comparing their spectral profiles after drug treatment in rats. The spectral profiles produced by typical antipsychotics chlorpromazine (5 mg/kg, i.p.) and haloperidol (0.5 mg/kg, i.p.) were differ from that by atypical antipsychotic clozapine (5 mg/kg, i.p.) in the rats treated with or without MK-801 treatment (0.2 mg/kg, i.p.) which produce behavioral abnormalities like hyperlocomotion and stereotypy. The dissimilarity between the states produced by antipsychotics and the control state was examined with the distance of the location of the canonical variables calculated by stepwise discriminant analysis with the relative band powers as input variables. Although clozapine produced more different state from normal state than typical antipsychotics, clozapine could reverse the abnormal schizophrenic state induced by MK-801 to the state closer to the normal state than the typical antipsychotics. The results suggest that atypical anesthetic can reverse the abnormal schizophrenic state with negative symptom to the normal state better than typical antipsychotic. The results indicate that the multivariate discriminant analysis using the spectral parameters can help differentiate the antipsychotics with different actions.

Background:
Although patients with lymphoma appear particularly vulnerable to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, the clinical evolution of coronavirus disease 2019 (COVID-19) in a patient with lymphoid malignancies has been under-represented, especially in relation to chemo-, chemo-immunotherapy.
Materials and Methods:
Among adult patients with lymphoma receiving treatment in a specialized lymphoma center at a 500-bed, university-affiliated hospital, we retrospectively reviewed the medical records of patients diagnosed with SARS-CoV-2 infection from January 2020 to April 2022.
Results:
A total of 117 patients with a median age of 53 years were included. One hundred twelves (95.7%) were non-Hodgkin lymphoma. Eighty-six patients (73.5%) were on active chemotherapy and 9 were post stem cell transplant state. Sixty-one patients had more than one comorbidity and 29 had hypogammaglobulinemia. Thirty-four patients (29.1%) had never received a COVID-19 vaccine. During a median follow-up of 134 days, COVID-19 pneumonia developed in 37 patients (31.6%). Excluding three patients who died before the 30 days, 31 out of 34 patients had ongoing symptomatic COVID-19. Eleven patients (9.4%) had post COVID-19 lung condition that persisted 90 days after COVID-19 diagnosis. Overall mortality was 10.3% (12 of 117), which was higher in patients with pneumonia. In multivariate analyses, age 65 years or older, follicular lymphoma, receiving rituximab maintenance therapy, and lack of vaccination were significantly associated with the development of COVID-19 pneumonia.
Conclusion
Patients with lymphoma are at high risk for developing pneumonia after SARS-CoV-2 infection and suffer from prolonged symptoms. More aggressive vaccination and protective measures for patients with lymphoma who have impaired humoral response related to rituximab maintenance therapy and hypogammaglobulinemia are needed.

PURPOSE: The purpose of this study was to assess the frequency of acute rheumatic fever(ARF) among children in Korea and to describe trends in its clinical characteristics compared to data from a previous study(1978-1987). METHODS: A mailed questionnaire survey sent to the pediatric departments of 13 general hospitals in Korea requested the total number of patients with ARF and its clinical manifestations from Jan. 1988 to Dec. 1997. These data were compared with the data from a previous study (1978-1987) to evaluate the clinical trends in occurrence and clinical manifestations of ARF during the last 20 years in Korea. RESULTS: The average number of patients with ARF for the 10-year period(1988-1997) was 0.74 per 1,000 annual pediatric inward patients. There was a significant decrease in incidence during the study period. There were 115 male and 85 female patients with ARF, and 97.5% of total patients were 6 to 15 years old. 126 out of 200 patients(63.0%) had a history of preceding upper respiratory infection(URI). The percentage of major manifestations were as follows; carditis(66.5%),polyarthritis(54.0%), erythema marginatum(12.0%), chorea(7.5%) and subcutaneous nodule (6.0%). Clinical findings of carditiswere cardiac murmur(91.0%), cardiomegaly in chest PA(34.6%), congestive heart failure(15.8%). The electrocardiographic findings were PR interval prolongation (37.6%), right ventricular hypertrophy (RVH) and left ventricular hypertrophy(LVH)(15.8%), QT interval prolongation(13.5%). Doppler echocardiographic valvular lesions were mitral insufficiency(96.2 %), aortic insufficiency(39.8%). Minor and other clinical manifestations were fever(69.0%), arthralgia (56.5%), sore throat(28.5%). CONCLUSION: There was a steady decrease in the number of patients with ARF during the study period from 1988 to 1997. A sudden decrease in number of patients with ARF between the two study periods is likely due to patients with valvular heart disease, possibility of double registration, and wide spread use of echocardiography for accurate diagnosis.

Left ventricular hypertrabeculation/noncompaction (LVHT) is an uncommon type of genetic cardiomyopathy characterized by trabeculations and recesses within the ventricular myocardium. LVHT is associated with diastolic or systolic dysfunction, thromboembolic complications, and arrhythmias, including atrial fibrillation, ventricular arrhythmias, atrioventricular block and Wolff-Parkinson-White syndrome. Herein, we describe a patient who presented with heart failure and wide-complex tachycardia. Echocardiography showed LVHT accompanied with severe mitral regurgitation. The electrophysiologic study revealed a fasciculo-ventricular accessory pathway and atrial flutter (AFL). The AFL was successfully treated with catheter ablation.
