Survival rate over a 5-year period were studied in a series of 658 proven primary lung cancer patients treated by thoracic surgeons at 8 institutes during the period from 1976 to 1987 in Korea. The study was designed as a multi-center cooperative work for the statistical analysis of the followup result. Clinical data of age, sex, morbidity, and staging of the tumor were assessed in 540 patients to evaluate their 5-year survival rates. Eventually, 405 resectable patients were analyzed by stage, cell type, surgical procedure, and TNM status. The 5-year actuarial survival rates by stage in the resectable group were: stage I 39.7%, II 30.6% III A 16.3%, III B 6.7%, and IV 0%. The 5-year survival rates by cell type were: squamous cell 31.9%, adenocarcinoma 21.2%, large cell 11%, and small cell 6%. The survival rates by surgical procedures were: lobectomy 30.7% and pneumonectomy 25.7%. The survival rates by TNM status in the operable group were: T1 34.7%, T2 26.8%, T3 7.5%, T4 5%; N1 23%, N2 10%, N3 3%; MO 21%, and M1 0%, respectively. The overall actuarial 5-year survival rate in the group of 405 resectable patients was 25.9%.

PURPOSE: To investigate the growth inhibitory effects, and the underlying mechanism of human colon cancer cell (HT-29) death, induced by a new synthetic bile acid derivative (HS-1200). MATERIALS AND METHODS: Human colon cancer cells (HT-29), in exponential growth phase, were treated with various concentrations of a new synthetic bile acid derivative (HS-1200). The growth inhibitory effects on HT-29 cells were examined using a trypan blue exclusion assay. The extent of apoptosis was determined using agarose gel electrophoresis, TUNEL assays and Hoechst staining. The apoptotic cell death was also confirmed by Western blotting of PARP, caspase-3 and DNA fragmentation factor (DFF) analysis. To investigate the involvement of mitochondria, we employed immunofluorescent staining of cytochrome c and mitochondrial membrane potential analyses. RESULTS: The dose required for the half maximal inhibition (IC50) of the HT-29 cell growth was 100~150 micro M of HS-1200. Several changes, associated with the apoptosis of the HT-29 cells, were reveal by the agarose gel eletrophoresis, TUNEL assays and Hoechst staining, following their treatment with 100 micro M of HS-1200. HS-1200 treatment also induced caspase-3, PARP and DFF degradations, and the western blotting showed the processed caspase-3 p20, PARP p85 and DFF p30 and p11 cleaved products. Mitochondrial events were also demonstrated. The cytochrome c staining indicated that cytochrome c had been released from the mitochondria in the HS-1200 treated cells. The mitochondrial membrane potential (deltaxm) was also prominently decreased in the HS-1200 treated cells. CONCLUSION: These findings suggest that the HS-1200 - induced apoptosis of human colon cancer cells (HT-29) is mediated via caspase and mitochondrial pathways.

Although there are some reports of malignant fibrous histiocytoma arising from the head and neck region, there hasn't been any reports on cases originating from the tongue base. We experienced a case of 29-year old female patient who visited our hospital with complaints of dyspnea, swallowing difficulty and a tongue based mass. On physical examination, she showed a huge tongue base mass filling the hypopharynx. After a temporary tracheostomy, she underwent a mass excision via transhyoid pharyngotomy approach. Postoperatively, she received radiation therapy for adjuvant treatment. She has been followed up without any evidence of the disease for 20 months.

Purpose:
The declining recruitment rate of pediatric residents in Korea has led to a decrease in the number of emergency departments (EDs) offering a 24/7 pediatric emergency care (PEC). This study evaluated the impact of reduced PEC hours on the utilization patterns of a single ED.
Methods:
We reviewed medical records of pediatric patients who were defined as individuals aged 14 years or younger undergoing pediatricians’ practices in a tertiary hospital ED in Korea. Given the reduction of PEC hours from full-time to 08:00-24:00 on September 27, 2022, the patients were grouped as those who visited during March 27, 2022-September 26, 2022 (“control”), and those who visited during September 27, 2022-March 26, 2023 (“reduction”). The following variables were analyzed between the 2 periods: the number of patients, age, sex, visits via ambulances, severity by the Korean Triage and Acuity Scale with high acuity (a level 1-2 of the scale), disease-related visits, time of visit, ED length of stay (EDLOS), disposition, chief complaints, and diagnoses.
Results:
Among 3,577 pediatric patients, 1,315 visited the ED during the reduction period, down by 41.9% in numbers from the control period. From the control to reduction periods, we observed an increase in the median age (from 3.0 years [interquartile range, 1.0-7.0] to 4.0 years [1.0-8.0]; P = 0.005) and decreases in the median EDLOS (from 140.0 minutes [80.0-217.0] to 104.0 minutes [54.0-169.8]; P < 0.001) and proportion of hospitalization (from 22.1% to 12.6%; P < 0.001). No change was observed in the proportions of highacuity cases or chief complaints. We noted decreases in infection-related diagnoses during the reduction.
Conclusion
Reducing PEC hours was associated with shorter EDLOS, fewer hospitalizations, and older age, with no difference in the severity. Even with reduced PEC hours, relevant resources should be redistributed to ensure the accessibility to PEC.

The objective of this study was to investigate the calf death and analyse the causes of the mortality by based on medical records and autopsy findings during 10 years in a large dairy farm. Total of 1,361 calf born and 146 calf dead during the invested period. Mortality rate was 10.7% and showed the big difference by year-specific mortality from 2.8% (4 calves) to 19.2% (28 calves). The highest rate of mortality was 1 week age (18.5%, 27 calves) and followed by 2 week age (11.6%, 17 calves) and mortality of more old calf tended to be reduced. The death less than 4 weeks and 8 weeks of age of the entire mortality accounted for 41.1% (60/146 calves) and 70.0% (102/146 calves), respectively. Causes of calf death were digestive diseases (53.4%), respiratory diseases (17.1%), musculoskeletal disease (8.2%), and systemic disease (8.2%) in order. Specific causes of calf death was highest in enteritis (43.2%), followed by pneumonia (14.4%), sepsis (8.2%) and fractures (3.4%). Seasonally, most of calf death happened in winter (48.6%) and then fall (21.2%). This results showed that enteritis and pneumonia are the main reason of calf death but other reasons were involved in calf death on the based on autopsy finding. On going research relating factors of calf mortality is needed.
