Abstract
BACKGROUND The aim of this multicentre prospective observational study was to identify the incidence, patient characteristics, diagnostic pathway, management and outcome of acute mesenteric ischaemia (AMI). METHODS All adult patients with clinical suspicion of AMI admitted or transferred to 32 participating hospitals from 06.06.2022 to 05.04.2023 were included. Participants who were subsequently shown not to have AMI or had localized intestinal gangrene due to strangulating bowel obstruction had only baseline and outcome data collected. RESULTS AMI occurred in 0.038% of adult admissions in participating acute care hospitals worldwide. From a total of 705 included patients, 418 patients had confirmed AMI. In 69% AMI was the primary reason for admission, while in 31% AMI occurred after having been admitted with another diagnosis. Median time from onset of symptoms to hospital admission in patients admitted due to AMI was 24 h (interquartile range 9-48h) and time from admission to diagnosis was 6h (1-12 h). Occlusive arterial AMI was diagnosed in 231 (55.3%), venous in 73 (17.5%), non-occlusive (NOMI) in 55 (13.2%), other type in 11 (2.6%) and the subtype could not be classified in 48 (11.5%) patients. Surgery was the initial management in 242 (58%) patients, of which 59 (24.4%) underwent revascularization. Endovascular revascularization alone was carried out in 54 (13%), conservative treatment in 76 (18%) and palliative care in 46 (11%) patients. From patients with occlusive arterial AMI, revascularization was undertaken in 104 (45%), with 40 (38%) of them in one site admitting selected patients. Overall in-hospital and 90-day mortality of AMI was 49% and 53.3%, respectively, and among subtypes was lowest for venous AMI (13.7% and 16.4%) and highest for NOMI (72.7% and 74.5%). There was a high variability between participating sites for most variables studied. CONCLUSIONS The overall incidence of AMI and AMI subtypes varies worldwide, and case ascertainment is challenging. Pre-hospital delay in presentation was greater than delays after arriving at hospital. Surgery without revascularization was the most common management approach. Nearly half of the patients with AMI died during their index hospitalization. Together, these findings suggest a need for greater awareness of AMI, and better guidance in diagnosis and management.

Abstract
BACKGROUND Acute mesenteric ischaemia (AMI) is a disease with different pathophysiological mechanisms, leading to a life-threatening condition that is difficult to diagnose based solely on clinical signs. Despite widely acknowledged need for biomarkers in diagnosis of AMI, a broad systematic review on all studied biomarkers in different types of AMI is currently lacking. The aim of this study was to estimate the diagnostic accuracy of all potential biomarkers of AMI studied in humans. METHODS A systematic literature search in PubMed, The Cochrane Library, Web of Science and Scopus was conducted in December 2022. Studies assessing potential biomarkers of AMI in (at least 10) adult patients and reporting their diagnostic accuracy were included. Meta-analyses of biomarkers' sensitivity, specificity, and positive and negative likelihood ratios were conducted. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed, and the study quality was assessed with the QUADAS-2 tool. RESULTS Seventy-five studies including a total of 9914 patients assessed 18 different biomarkers in serum/plasma and one in urine (each reported in at least two studies), which were included in meta-analyses. None of the biomarkers reached a conclusive level for accurate prediction. The best predictive value overall (all studies with any type and stage of AMI pooled) was observed for Ischaemia-modified albumin (2 studies, sensitivity 94.7 and specificity 90.5), interleukin-6 (n = 4, 96.3 and 82.6), procalcitonin (n = 6, 80.1 and 86.7), and intestinal fatty acid-binding protein (I-FABP) measured in serum (n = 16, 73.9 and 90.5) or in urine (n = 4, 87.9 and 78.9). In assessment of transmural mesenteric ischaemia, urinary I-FABP (n = 2, 92.3 and 85.2) and D-dimer (n = 3, 87.6 and 83.6) showed moderate predictive value. Overall risk of bias was high, mainly because of selected study populations and unclear timings of the biomarker measurements after onset of symptoms. Combinations of biomarkers were rarely studied, not allowing meta-analyses. CONCLUSIONS None of the studied biomarkers had sufficient sensitivity and specificity to diagnose AMI, although some biomarkers showed moderate predictive accuracy. Future studies should focus on timing of measurements of biomarkers, distinguishing between early stage and transmural necrosis, and between different types of AMI. Additionally, studies on combinations of biomarkers are warranted. PROSPERO registration: CRD42022379341.

Abstract
Background: Ultrasonography (US) and the 99mTc-sestamibi parathyroid scan (SPS) may have suboptimal accuracy when detecting the localization of enlarged parathyroid gland(s) (PTG). Therefore, the more accurate four-dimensional computed tomography scan (4D-CT) has been employed for PTG imaging. Currently, there is a paucity of data evaluating the utility of 4D-CT in low caseload settings. Aim and Objectives: To evaluate the impact of PTG imaging, using 4D-CT in conjunction with its intraoperatively displayed results, on the outcomes of surgical PTX. Materials and Methods: A single-center retrospective analysis of surgically treated patients with pHPT from 01/2010 to 01/2021 was conducted. An evaluation of the impact of the preoperative imaging modalities on the results of surgical treatment was carried out. Results: During the study period, 290 PTX were performed; 45 cases were excluded due to surgery for secondary, tertiary or recurrent HPT, or due to the use of alternative imaging techniques. The remaining 245 patients were included in the study. US was carried out for PTG imaging in 236 (96.3%), SPS in 93 (38.0%), and 4D-CT in 52 patients (21.2%). The use of 4D-CT was associated with a significantly higher rate of successful localization of enlarged PTG (49 cases, 94.2%) compared to US and SPS (74 cases, 31.4%, and 54 cases, 58.1%, respectively). We distinguished between three groups of patients based on preoperative imaging: (1) PTG lateralization via US or SPS in 106 (43.3%) cases; (2) precise localization of PTG via 4D-CT in 49 (20.0%) patients; and (3) in 90 cases (36.7%), PTG imaging failed to localize an enlarged gland. The group of 4D-CT localization had significantly shorter operative time, lower rate of simultaneous thyroid resections, as well as lower rate of removal of ≥2 PTG, compared to the other groups. The 4D-CT imaging was also associated with the lowest perioperative morbidity and with the lowest median PTH in the one month follow-up; however, compared to the other groups, these differences were statistically not significant. The implementation of 4D-CT (since 01/2018) was associated with a decrease in the need for redo surgery (from 11.5% to 7.3%) and significantly increased the annual case load of PTX at our institution (from 15.3 to 41.0) compared to the period before 4D-CT diagnostics. Conclusions: 4D-CT imaging enabled to precisely locate almost 95% of enlarged PTG in patients with pHPT. Accurate localization and intraoperatively displayed imaging results are useful guides for surgeons to make PTX a faster and safer procedure in a low-volume center.

Abstract
BACKGROUND There is a lack of population-based studies on acute mesenteric ischemia (AMI). We have therefore performed a nationwide epidemiological study in Estonia, addressing incidence, demographics, interventions and mortality of AMI. METHODS A retrospective population-based review was conducted of all adult cases of AMI accrued from the digital Estonian Health Insurance Fund and Causes of Death Registry for 2016-2020 based on international classification of diseases (ICD-10) diagnostic codes and procedure codes (NOMESCO). RESULTS Overall, 577 cases of AMI were identified-an annual incidence of 8.7 per 100,000. The median age was 79 (range 32-104) and 57% were female. Predominating comorbidities included hypertensive disease (81%), atherosclerosis (67%), and atrial fibrillation (52%). The majority of cases (60%) were caused by superior mesenteric artery occlusion (thrombosis 54%, embolism 12%, and unclear 34%). Inferior mesenteric artery occlusion occurred in 7%, non-occlusive mesenteric ischemia in 7%, venous thrombosis in 4%, whereas the type remained unclear in 21% of cases. 40% of patients received intervention (revascularization and/or intestinal resection) and 13% active non-operative treatment. In 21% an exploratory laparotomy or laparoscopy revealed unsalvageable bowel prompting end-of-life care, which was the only management in a further 25% of cases. CONCLUSIONS The population-based annual incidence of AMI in Estonia was 8.7 per 100,000 during the study period. The overall hospital mortality and 1 year mortality were 64% and 74%, respectively. In the 53% of patients who received active treatment hospital mortality was 32% and 1 year all-cause mortality was 51%. TRIAL REGISTRATION ClinicalTrials.gov Identifier NCT04867499.

Abstract
BACKGROUND Chronic pancreatitis (CP) is a long-lasting disease frequently associated with complications for which there is no comprehensive pathophysiological classification.
AIM The aims of this study were to: Propose a pathophysiological classification of the complications of CP; evaluate their prevalence in a surgical cohort prior to, and following surgical management; and assess the impact of the surgical treatment on the occurrence of new complications of CP during follow-up. We hypothesized that optimal surgical treatment can resolve existing complications and reduce the risk of new complications, with the exclusion of pancreatic insufficiency. The primary outcomes were prevalence of complications of CP at baseline (prior to surgical treatment) and occurrence of new complications during follow-up.
METHODS After institutional review board approval, a prospective observational cohort study with long-term follow-up (up to 20.4 years) was conducted. All consecutive single-center adult patients (≥ 18 years of age) with CP according to the criteria of the American Pancreas Association subjected to surgical management between 1997 and 2021, were included. The prevalence of CP complications evaluated, according to the proposed classification, in a surgical cohort of 166 patients. Development of the pathophysiological classification was based on a literature review on the clinical presentation, course, and complications of CP, as well a review of previous classification systems of CP.
RESULTS We distinguished four groups of complications: Pancreatic duct complications, peripancreatic complications, pancreatic hemorrhages, and pancreatic insufficiency (exocrine and endocrine). Their baseline prevalence was 20.5%, 23.5%, 10.2%, 31.3%, and 27.1%, respectively. Surgical treatment was highly effective in avoiding new complications in the first and third groups. In the group of peripancreatic complications, the 15-year Kaplan-Meier prevalence of new complications was 12.1%. The prevalence of pancreatic exocrine and endocrine insufficiency increased during follow-up, being 66.4% and 47.1%, respectively, at 15 years following surgery. Pancreatoduodenal resection resulted optimal results in avoiding new peripancreatic complications, but was associated with the highest rate of pancreatic exocrine insufficiency.
CONCLUSION The proposed complication classification improves the understanding of CP. It could be beneficial for clinical decision making, as it provides an opportunity for more comprehensive judgement on patient’s needs on the one hand, and on the pros and cons of the treatment under consideration, on the other. The presence of complications of CP and the risk of development of new ones should be among the main determinants of surgical choice.

Abstract
Flood syndrome is a rare condition, where a patient with ascites suffers sudden umbilical hernia rupture and a subsequent drainage of ascitic fluid from the abdominal cavity. The cause of ascites is usually liver cirrhosis. Complications associated with cirrhosis of the liver make Flood syndrome difficult to manage. In these cases, conservative management has been associated with high morbidity. We describe, to our knowledge, for the first time a patient with Flood syndrome caused by right-sided heart failure. We also show that conservative treatment gives great initial outcome and is a viable option for this type of Flood syndrome.

Abstract
BACKGROUND The Partington-Rochelle pancreaticojejunostomy (PJ) is an essential management option for patients with chronic pancreatitis (CP) associated with intractable pain and a dilated pancreatic duct (PD). Wide ductotomy and long PJ (L-PJ) have been advocated as the standard of care to ensure full PD decompression. However, the role of short PJ (S-PJ) in a uniformly dilated PD has not yet been evaluated.
AIM To evaluate the possible advantages and disadvantages of S-PJ and L-PJ and to interpret the perspective of S-PJ in the treatment of CP.
METHODS A retrospective review of prospectively collected cohort data was conducted on surgically treated CP patients subjected to side-to-side PJ. The length of the PJ was adapted to anatomical alterations in PD. A comparison was made of S-PJ (< 50 mm) for uniformly dilated PD and L-PJ (50-100 mm) in the setting of multiple PD strictures, calcifications and dilatations. We hypothesized that S-PJ and L-PJ ensure comparable clinical outcomes. The primary outcomes were pain relief and quality of life (QOL); the secondary outcomes were perioperative characteristics, body weight, patients’ satisfaction with treatment, and readmission rate due to CP.
RESULTS Overall, 91 patients underwent side-to-side PJ for CP, including S-PJ in 46 patients and L-PJ in 45 patients. S-PJ resulted in better perioperative outcomes: Significantly shorter operative time (107.5 min vs 134 min), lower need for intraoperative (0% vs 15.6%) and total (2.2% vs 31.1%) blood transfusions, and lower rate of perioperative complications (6.5% vs 17.8%). We noted no significant difference in pain relief, improvement in QOL, body weight gain, patients’ satisfaction with surgical treatment, or readmission rate due to CP.
CONCLUSION Based on our data, in the setting of a uniformly dilated PD, S-PJ provides adequate decompression of the PD. As the clinical outcomes following S-PJ are not inferior to those of L-PJ, S-PJ should be preferred as a surgical option in the case of a uniformly dilated PD.

Abstract
BACKGROUND/OBJECTIVES Chronic pancreatitis (CP) is a complex disease with a high complications rate, poor quality of life and considerable mortality. Prospective investigations on long-term outcomes in chronic pancreatitis are scarce. Thus, we aimed to assess long-term survival, causes of death and impact of risk factors on survival in a cohort of surgically managed patients with chronic pancreatitis. METHODS After IRB approval, a prospective longitudinal cohort study with long-term follow-up (up to 19.6 years) was conducted. All consecutive single center patients operated between 1997 and 2019 were included. Data on health and social status, risk behavior, history of CP, indications for surgery, comorbidities and causes of death were collected. Survival analysis was performed using Kaplan-Meier analysis. Cox proportional multivariate hazard regression was used to assess the impact of risk factors on mortality. The results are reported as the hazard ratio (HR) with the 95% confidence interval (CI). The log-rank test was used to test for differences in survival between groups. RESULTS A total of 161 patients with CP were subjected to operative management due to chronic pain or local complications of CP. Forty-eight patients (29.8%) died during the follow-up period. Mortality rate was 32.8 per 1000 patient-years (PY) since the diagnosis of CP. Standardized mortality ratio (SMR) was 1.8 (2.7 for the subgroup of continuous alcohol users). Median survival after surgical treatment was 13.3 years. Univariate analysis revealed the following risk factors on survival: preoperative and postoperative continuous moderate or heavy alcohol consumption, heavy smoking, age ≥50 years, Charlson's comorbidity index (CCI) ≥4 and 2-3, unemployment, disability, insulin-dependent diabetes, pancreatic exocrine insufficiency (PEI), and low body mass index (BMI). In multivariate regression analysis lower survival was associated with continuous moderate/heavy alcohol consumption (hazard ratio (HR) 2.27), history of heavy smoking (HR 4.40), unemployment (HR 2.49), CCI 2-3 and ≥4 (HR 2.53 and HR 3.16, respectively), and BMI <18.5 (HR 4.01). Behavioral risk factors accounted for the vast majority of deaths due to chronic alcoholic liver disease (21 cases, 43.7%), smoking-related diseases (15 cases, 31.3%). CP-related mortality was 4.2%. CONCLUSIONS Long-term outcomes of surgically treated chronic pancreatitis was associated with low CP-related mortality. Alcohol-related and smoking-related diseases caused the vast majority of deaths. Thus, surgery provides the best results in patients, preventing postsurgical relapse of original behavioral risks. For achieving this, ongoing postoperative support would be highly beneficial.

Abstract
OBJECTIVES Pre-exposure prophylaxis (PrEP) for HIV infection is an important intervention for control of the HIV epidemic. The incidence of HIV infection is increasing in the countries of Central and Eastern Europe (CEE). Therefore, we investigated the change in PrEP use in CEE over time. METHODS The Euroguidelines in Central and Eastern Europe (ECEE) Network Group was initiated in February 2016 to compare standards of care for HIV and viral hepatitis infections in CEE. Data on access to PrEP were collected from 23 countries through online surveys in May-June 2017 (76 respondents) and in November 2018-May 2019 (28 respondents). RESULTS About 34.2% of respondents stated that tenofovir/emtricitabine (TDF/FTC) was licensed for use in their country in 2017, and 66.7% that it was licensed for use in 2018 (P = 0.02). PrEP was recommended in national guidelines in 39.5% of responses in 2017 and 40.7% in 2018 (P = 0.378). About 70.7% of respondents were aware of "informal" PrEP use in 2017, while 66.6% were aware of this in 2018 (P = 0.698). In 2018, there were 53 centres offering PreP (the highest numbers in Poland and Romania), whereas six countries had no centres offering PreP. The estimated number of HIV-negative people on PreP in the region was 4500 in 2018. Generic TDF/FTC costs (in Euros) ranged from €10 (Romania) to €256.92 (Slovakia), while brand TDF/FTC costs ranged from €60 (Albania) to €853 (Finland). CONCLUSIONS Although the process of licensing TDF/FTC use for PrEP has improved, this is not yet reflected in the guidelines, nor has there been a reduction in the "informal" use of PrEP. PrEP remains a rarely used preventive method in CEE countries.

Abstract
Axial torsion and necrosis of Meckel’s diverticulum causing simultaneous mechanical small bowel obstruction are the rarest complications of this congenital anomaly. This kind of pathology has been reported only eleven times. Our case report presents this very unusual case of Meckel’s diverticulum. A 41-year-old man presented at the emergency department with complaints of crampy abdominal pain, nausea and retention of stool and gases. Clinical diagnosis was small bowel obstruction. Because the origin of obstruction was unknown, computer tomography was indicated. Computed tomography (CT)-scan revealed dilated small bowel loops with multiple air-fluid levels; the oral contrast medium had reached the jejunum and proximal parts of the ileum but not the distal small bowel loops or the large bowel; in the right mid-abdomen there was a 11 cm × 6.4 cm × 7.8 cm fluid containing cavity with thickened wall, which was considered a dilated bowel-loop or cyst or diverticulum. Initially the patient was treated conservatively. Because of persistent abdominal pain emergency laparotomy was indicated. Abdominal exploration revealed distended small bowel loops proximal to the obstruction, and a large (12 cm × 14 cm) Meckel’s diverticulum at the site of obstruction. Meckel’s diverticulum was axially rotated by 720°, which caused small bowel obstruction and diverticular necrosis. About 20 cm of the small bowel with Meckel’s diverticulum was resected. The postoperative course was uneventful and the patient was discharged on the fifth postoperative day. We recommend CT-scan as the most useful diagnostic tool in bowel obstruction of unknown origin. In cases of Meckel’s diverticulum causing small bowel obstruction, prompt surgical treatment is indicated; delay in diagnosis and in adequate treatment may lead to bowel necrosis and peritonitis.

Abstract
A new scanning transmission electron microscope has been developed for three-dimensional (3D) observations of nanostructures. Using double spherical fulcra, accurate eucentric rotation was achieved. Cylindrical specimens for 3D-observation were prepared by a microsampling technique using a focused ion beam. Copper via-holes of a semiconductor memory device and ZnO particles were observed by the 3D-STEM from different directions, and 3D-data of the ZnO particles were successfully reconstructed in a topography mode.

Abstract
Pulmonary angioplasty was successfully performed in two patients using the vascular clip system (VCS). The portion of the pulmonary artery which was directly invaded by primary lung cancer was partially resected. The VCS was used to quickly and easily repair the vascular defect. No bleeding was noted from the clipped vascular walls. Both patients had uneventful recoveries.

Abstract
Although various materials have been used for reinforcement in lung-volume-reduction surgery to buttress pulmonary staple-line, absorbable materials are not available for use in thoracoscopic surgery. Moreover, even nonabsorbable types of reinforcements have been used only for lung volume reduction surgery. However, elderly patients with spontaneous pneumothorax secondary to emphysematous lung are well treated with staple-line reinforcement. The authors developed a new type of polyglycolic acid felt to buttress staple-line. This felt is absorbable, easier to cut with a stapler knife than is the conventional polyglycolic acid felt, and inexpensive enough to use for various types of thoracic surgeries for emphysematous lungs in Japan, and it can be attached to staplers with a small amount of fibrin glue. These strips were used to reinforce pulmonary staple lines for resection of emphysematous lungs in 14 patients: pulmonary emphysema (n = 1), bilateral giant bullae (n = 1), ipsilateral giant bullae (n = 6), spontaneous pneumothorax with multiple bullae in an emphysematous lung (n = 5), and lung cancer in a patient with pulmonary emphysema (n = 1). There were no air leaks during surgery. Air leaks were noted in three patients after surgery. In two patients, the air leaks stopped within 2 weeks. In one patient, the air leak was found to originate from an untouched lobe during reoperation. No infection or allergic reaction developed in a patient during a mean follow-up of 12 months (range, 1 to 24 months).

Abstract
We report a rare case of pulmonary arteriovenous malformation (PAVM) with cerebellar abscess. The patient was 38-year-old woman who admitted to the local hospital for headache and fever. Subsequently, her condition became critical with consciousness disturbance, and hypoxemia. Brain computed tomography (CT) and chest CT revealed cerebellar abscess and PAVM. She was referred to our hospital for the surgery. Pulmonary angiography demonstrated multiple pulmonary arteriovenous fistulas in the right middle lobe and a single nodular pulmonary arteriovenous fistula in the right S8 (10 x 10 mm). After the drainage for the brain abscess, lobectomy of the right middle lobe and the excision of the nodal fistula in the right S8 were successfully performed in the two-staged operation. The patient has done well with no complication and her hypoxemia was improved.

Abstract
The brains of 125 schizophrenic patients (DSM-IV criteria) without other major diseases likely to affect brain morphology were examined at autopsy in our hospital for an evaluation of the number of neurofibrillary tangles (NFT) and senile plaques (SP) as indicators of the incidence of Alzheimer's disease (AD) brain pathology. The clinical degree of dementia and the presence or absence of delirium and Parkinsonism were determined in a review of the patients' charts. No significant difference in the degree of AD brain pathology between the 12 schizophrenics more than 75 years old and 12 age-matched normal controls was present. We conclude that AD pathology seems to be no more frequent among schizophrenic patients than in the normal population, and that the severe cognitive impairment observed in schizophrenics is based on neither neuronal degeneration nor neuronal loss like that occurring in AD. We believe that future morphological studies of cognitive impairments in schizophrenics will require a more detailed investigation at the receptor level.

Abstract
We report an elderly patient with progressive supranuclear palsy (PSP) who showed no neurological signs clinically. A 70-year-old man presented with irritation and poor hygiene, thereafter he showed excitement and violence. A cranial CT scan revealed bilateral moderate atrophy of the temporal lobes and slight enlargement of the lateral ventricle. The brain stem was slightly atrophic. Although he died at the age of 80 years, he had no neurological signs throughout the clinical course. Neuropathological study showed typical findings of PSP, neuronal loss with gliosis and neurofibrillary tangles in the basal ganglia, amygdala, midbrain, pons, dentate nucleus and inferior olivary nucleus. Staining by Gallyas-Braak methods revealed argyrophilic and tau-positive glial fibrillary tangles in the cerebral cortex. Neurofibrillary tangles showed greater frequency than usual for the physiological level in that age group in the hippocampus regions as well as in the amygdala. The possibility that the psychotic symptoms, mainly personality change, are connected with the degeneration of limbic system is indicated. Since there have not been any previous reports of PSP without neurological signs, this case represents an important in terms of clinico-pathological variation of PSP. We suggest that there is discrepancy between symptomatic and neuropathological aspects in elderly patients with PSP.

Abstract
A 57-year-old woman showed progressive sensory aphasia as an initial symptom, and then developed total aphasia within 6 years and, finally, severe dementia. Neuropathologically, the cerebral cortex was most severely affected in the superior and transverse temporal gyri, and subsequently in the inferior frontal gyrus, especially in the pars opercularis. The degeneration in the subcortical grey matter was most severe in the substantia nigra, and it was moderate to mild in the ventral part of thalamus, globus pallidus and striatum. Cytopathologically, in addition to achromatic ballooned neurons, massive taupositive types of cytosekeletal abnormalities were observed both in neurons and glia, mainly in the degenerating region. This cytoskeletal pathology coincided with that reported in corticobasal degeneration (CBD). On Bodian staining, only a few neurofibrillary tangles were found in the entorhinal pre-alpha layer and substantia nigra. Pick's bodies and senile plaques could not be found. This case is thought to represent a type of CBD, but with its cortical lesion focus located in the speech area instead of the frontoparietal region. A survey of 28 pathologically evaluated cases of CBD revealed two similar cases, both of which began with progressive aphasia and presented cortical degeneration in the superior temporal gyrus. An overview of CBD cases clarified the features in another group of cases, in which the cerebral accentuated focus was shifted forward from the central region, clinically resembling Pick's disease. The clinical manifestations in CBD seem to be the expression of these diverse cortical lesions. Primary progressive aphasia may include cases of CBD with involvement of the language center.

Abstract
"Diffuse neurofibrillary tangles with calcification (DNTC)" is a slowly progressive form of presenile dementia characterized by localized temporal atrophy, pronounced calcareous deposits and numerous neurofibrillary tangles (NFTs) without senile plaques. We report a 70-year-old woman with DNTC, multiple infarctions and hyaline arteriosclerosis. This case was clinically characterized by persistent delusional ideas and personality changes. Intellectual deterioration was mild, and no focal manifestations were noted. Neuropathologically, numerous NFTs were seen distributed primarily in the hippocampal region, and massive calcareous deposits were observed in the cerebrum, basal ganglia and cerebellum. There were no senile plaques. Although the findings in this case were compatible with a diagnosis of DNTC, certain additional findings were also noted. The first was the presence of multiple infarctions in the basal ganglia and hyaline arteriosclerosis. Although these lesions may have been induced by hypertension, our review of previous reports of DNTC revealed a high incidence of arteriosclerosis. The second was the absence of lobar atrophy, which may have been due to the cerebral edema caused by the subdural hemorrhage or related to the relatively short duration of the illness. The dilatation of the temporal horn of the lateral ventricle and prominent NFTs in the hippocampal region indicate the initial occurrence of the disease in this region.

Abstract
Fourteen healthy adult Japanese females were selected to participate in a comparative study of hair plucking (a temporary hair removal technique) and the blend method (a permanent hair removal technique). The effectiveness of permanent hair removal and the safety of the blend method were examined in this study. If hairs of the left axilla were removed by the blend method, then hairs of the right axilla were removed by plucking, and vice versa. Every hair was removed and the number of hairs was counted each time. Sessions were conducted every three weeks, and the experiment continued until no new hair growth was seen using the same experimental standard. Electrologists with more than 1000 hours of experience were selected to perform electrolysis. Examinations of the axilla, before and after each test, were conducted by the authors. The results showed that the number of hairs decreased in the axilla with each session using the blend method: permanent hair removal was achieved in an average of 26.8 weeks or 9.9 sessions. However, the number of hairs did not decrease in the axilla after plucking. Also, there were no reports of hair removal related side-effects in this study. It was thus demonstrated that the blend method is a safe and effective way of achieving permanent hair removal.

Abstract
The risk from environmental radon levels is not higher now than in the past, when residential exposures were not considered to be a significant health hazard. The majority of the radon dose is not from radon itself, but from short-lived alpha-emitting radon daughters, most notably 218Po(T1/2 3 min) and 214Po (T1/2 0.164 msec) along with beta particles from 214Bi (T1/2 19.7 min). Radon gas can penetrate homes from many sources and in various fashions. Measuring radon in homes is simple and relatively inexpensive and may be accomplished in a variety of ways. Although it is not possible to radon-proof a house, it is possible to reduce the level. In high radon areas, if the average level is higher than 4-8 pCi/liter (NCRP recommended level is 8 pCi/liter; EPA recommended level is 4 pCi/liter), appropriate action is advised. The shape of the dose response curves for miners exposed to alpha-emitting particles in the workplace is consistent with current biologic knowledge. It is linear in the low dose range and saturates in the high dose range. No detectable increase in lung cancer frequency is seen in the lowest exposed miners (those with exposures < 120 WLM, the relevant dose interval for most homes). Evidence for a health effect from radon exposure is based on data from animal studies and epidemiologic studies of mines. Extensive radiobiologic data predict a linear dose-response curve in the low dose region due to poor biological repair mechanisms for the high density of ionizing events that alpha particles create. However, no compelling evidence for increased cancer risks has yet been demonstrated from "acceptable" levels (< 4-8 pCi/liter).

Abstract
BACKGROUND The altered and anomalous expression of carbohydrate antigens (CA) occur in patients with lung carcinomas. METHODS To investigate the relationship between prognosis and immunohistochemical findings of CA in serum and pulmonary adenocarcinomas (PA), PA specimens surgically resected from 102 patients were studied with the use of A, B, H, Lewis(Le)a, Le(b), Le(x), Le(y), sialyl Le(a) (FH-7), sialyl Le(x-i) (SLX) (FH-6), sialosyl Tn (TKH-2), and CA 19-9. The Lewis blood group types were determined by the dot blotting method on patients' serum using monoclonal anti-Le(a), Le(b), Le(x), and Le(y). Formalin-fixed paraffin-embedded PA sections were stained using the avidin-biotin-peroxidase complex methods. RESULTS There was no correlation between the patients' postoperative survival and tissue expression of CA, although survival correlated with the clinical stages, histologic differentiation of PA, and serum SLX in Stage 4. The higher the positive rate of both Le(b) and Le(y), the better their differentiation in PA specimens. Regardless of blood group type, PA showed high positive reactions for FH-6 (88%) and Le(y) (87%). The serum concentration of CA 19-9 correlated with immunohistochemical reactions of tumors (Spearman correlation coefficient = 0.33, P = 0.02). The expression of Le(a) in Lewis (a-b+) phenotype patients and Type 2 CA, such as Le(y) and FH-6, is characteristic in PA. CONCLUSIONS The findings suggest that CA tissue expression may not reflect postoperative survival length of patients with PA, but biological aberrant fucosylation or sialylation as well as morphologic alteration may occur in neoplastic cells.

Abstract
We describe the autopsy finding in a male patient with senile dementia of unusually prolonged total duration, who had exhibited atypical neuropathologic findings. During clinical course, memory disturbance had been more prominent than deterioration of other cognitive functions. Neuropathologic examination revealed neurofibrillary changes which were prominent in the hippocampal region and scattered in the amygdala and in the predilection sites of the hypothalamus and brain stem. This distributional pattern was that in Alzheimer-type dementia. The most characteristic finding was scanty senile plaques, which were scattered predominantly in the basal and medial portion of the frontal lobe. Although the clinical course and pathological findings of this case were in slight degree and deviated from those in usual senile dementia, it is thought that the entity in this case was dementia of the Alzheimer-type.

Abstract
Ultrastructural examination of ghost tangles in an autopsy case of long-term Alzheimer's disease revealed, in addition to degenerate neurites containing paired helical filaments (PHF), astrocytic processes which included PHF. This finding suggests either that astrocytes in ghost tangles possess the capacity to produce PHF or that PHF are incorporated into astrocytes by endocytosis.

Abstract
A simple method has been developed for the determination of the aminoglycoside antibiotic isepamicin (ISP) in whole blood, using dried blood spots (DBSs) on filter-paper. ISP in the DBSs were recovered most effectively in 0.5 M Na2HPO4-NaH2PO4 buffer (pH 7) by incubation for 30 minutes at 35 degrees C in an ultrafiltration tube. The eluates from the DBS papers were centrifuged at 3,000 x g for 10 minutes. The clear, colorless filtrates were transferred to an Abbott TDx cartridge for measurement by the fluorescence polarization immunoassay. The lower limit for the quantitative determination of ISP in the DBS was 2.5 micrograms per ml of whole blood. The method permits a simple collection of blood at a microliter level and should prove particularly useful for therapeutic drug monitoring of ISP in blood at effective levels in pediatric and geriatric patients.

Abstract
We have previously shown that tuberculous pleurisy possesses a high level of adenosine deaminase (ADA) which is predominantly composed of ADA2. In this paper, we report the cases of tuberculous pleural effusion which contained mainly ADA1. In these cases, mycobacterium tuberculosis was positive by smear examination and/or culture and granulocytes were found to be major components. Analysis of lactate dehydrogenase (LDH) revealed that its activity was high and LDH5 occupied about 50% of total activity. In the tubercle bacillus negative cases, lymphocytes were the main components and the levels of LDH containing mostly LDH3 were low. It was assumed that the difference in LDH activity and isozyme pattern is due to the differential presence of leukocytes in pleurisy i.e., granulocytes and lymphocytes in tubercle bacillus positive and negative pleurisy, respectively. In conclusion, tuberculous pleural effusions can be divided into two groups on the basis of ADA and LDH activities and isozymes which may reflect the presence of mycobacterium tuberculosis.

Abstract
As a thoracoscopic treatment for spontaneous pneumothorax, electrocautery has been mainly used. But contact type electrocautery has a risk of perforation of blebs. We adopted carbon monoxide laser (wave length 5.4 microns) and good coagulation shrinkage of blebs could be obtained by non-contact irradiation. CO laser was delivered by As-S glass fiber and power of fiber tip was 2-4 W. Compared with Nd-YAG laser (wavelength 1.06 microns), CO laser showed lower risk of perforation of blebs. Thoracoscopic CO laser coagulation shrinkage of blebs proved to be a important method of treatment for patient of spontaneous pneumothorax.

Abstract
A variety of viral and cellular oncogenes have been described with differing mechanisms of action but with the common property of inducing morphologic alteration of cells in culture. Subclonal lines of oncogene expressing cells have been shown to produce tumors in vivo. Expression of the N-ras oncogene in embryo fibroblast NIH/3T3 cells has been demonstrated to increase radioresistance in vitro, and these results have been confirmed and extended to human cell lines expressing the c-raf oncogene. In the present report, we have examined the effects of expression of the c-fms, v-abl, or v-myc oncogene in a clonal hematopoietic progenitor cell line 32D cl 3. The 32D cell line is nonmalignant in vivo and is dependent upon a source of Interleukin-3 (IL-3) for growth in vitro. The radiation survival of 32D cl 3 cells transfected and expressed in the c-fms oncogene showed significant increase in the radioresistance at both 5 cGy/min and 116 cGy/min. A clone of 32D cl 3 transfected and expressing the v-myc oncogene demonstrated increased radioresistance at both dose rates. Results of split dose experiments suggested significant repair of sublethal irradiation damage of 32D-v-abl cells. Results were compared with expression of the same v-abl oncogene in the NIH/3T3 embryo fibroblast cell line. The data demonstrate that gamma irradiation resistance is significantly increased by each oncogene expressed in 32D cl 3 cells. The data on cell line 32D cl 3 may correlate with the radioresistance of v-abl expressing human hematopoietic cell malignancies treated by irradiation therapy.

Abstract
We report the result of treatment for thirty-two patients whose chief complaint was hemoptysis and represent the therapeutic guide line for hemoptysis. In thirty-two cases, there were twenty men and twelve women and average of age was fifty-two years old. Twenty-nine of them were chronic lung diseases such as tuberculosis and bronchiectasis and only three cases have malignant tumors. Two of them recovered with conservative therapy and bronchial arteriography (BAG) have been performed in thirty patients in order to determine the bleeding foci, BAG was failed in two cases, but these two cases have been recovered with following up, BAG was succeeded in twenty-eight cases and twelve cases of them could not been determined the bleeding foci by angiography and could be controlled using hemostatic and antibiotic agents. Embolization of bronchial arteries with gelatin sponge have been performed in sixteen cases and made success in eleven cases. In ten of these cases, BAE was effective less than two times. Only one of silicosis with restrictive lung function was considered contraindication of surgery and recovered by three times of BAE. Four cases of five uneffective BAE (rebleeding after two times of BAE) have been treated by operation in good course. But one case complicated with WPW syndrome has died because of aspiration pneumonia without operation. In our institute, the rate of operation for hemoptysis was low as 13% of thirty-two cases. In order to consider the indication of surgery, bronchial arteriography was essential to determine bleeding foci and BAE was effective in over 80% of hemoptysis.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Among 287 patients underwent pulmonary resection between Mar 1978 and Dec 1989, 49 were proved pathologically to have their primary tumor of 3 cm or less in the greatest dimension. Twelve of these 49 classified to stage III A by the modiastinal lymph node metastasis or stage IV by the pulmonary metastasis. The histologic type of tumor was adenocarcinoma in 10 and squamous cell carcinoma in 2. Mode of surgical treatment consisted of pneumonectomy in 2, lobectomy in 8, segmentectomy or wedge resection in 2, and complete mediastinal lymph node dissection was performed in all but 2. Survival rate in 1, 3, 5 year was 100%, 38.1% and 38.1% in 9 with stage III A disease, and 100%, 100% and 50% in 3 with stage IV disease, respectively, and significant difference was noted in comparison with control group with larger tumor in each stage (p less than 0.05). From these results, we concluded that patients with small primary tumor could expect longer survival after surgical treatment, even if mediastinal lymph node metastasis or pulmonary metastasis was present.

Abstract
The anterior horn and lateral ventricular sizes of the brain CT were selected for measurement and comparison between 47 schizophrenic patients and 48 neurotic cases, which constituted the control subjects. The ventricular brain ratio (VBR) and the linear ratio (LR 1-6) in multiple age groups were calculated, analyzed and compared using the Student's t test, the two-way ANOVA and Bonferroni's methods. It was found that the VBR of the anterior horn and modified bicaudate cerebroventricular index of the teenage schizophrenics were significantly greater than those of the teenage controls (p less than 0.01) and the ventricular sizes were not associated with the different stages of age except for the cases of the teenage group. These results support the hypothesis of previous investigators that the ventricular enlargement is present early in the course of schizophrenia and provide additional evidence that in teenage schizophrenic patients there is a tendency of the enlargement of the anterior horn of the lateral ventricle which may be related with a morphological vulnerability in the prefrontal cortex.

Abstract
The hematopoietic and stromal cell-specific properties of the cells involved in gamma irradiation leukemogenesis in vitro were defined. Cocultivation of clonal factor-dependent (FD), interleukin 3 (IL-3)-dependent cell lines 32D cl 3 or B6SUtA, or dual IL-3-/granulocyte-macrophage colony-stimulating factor (GM-CSF)-dependent cell lines FDC-P1 or bg/bg d64 was carried out with clonal stromal cell lines D2XRII, GB1/6, +/+ 2.4, or Sld3. FD cell lines were added to control or 5000-cGy-irradiated plateau phase monolayer cultures of each stromal cell line, and parameters of stem cell engraftment and malignant transformation in vitro were quantitated. Cobblestone island formation by FD cells, cumulative production of nonadherent hematopoietic cells, and evolution of tumorigenic factor-independent (FI) subclonal lines were quantitated over 5-8 weeks. There was no detectable evolution of FI sublines with 32D cl 3, B6SUtA, or bg/bg d64 cells cocultivated with control or irradiated Sld3 stromal cells. IL-3-dependent cell lines 32D cl 3 or B6SUtA formed small 10- to 49-cell cobblestone "clusters" at low frequency on control or irradiated D2XRII, showed limited proliferation for less than 1 week, and showed no detectable evolution of FI cell lines. Subclones of 32D cl 3 derived by transfection and expression of recombinant oncogenes v-sis, or c-myc, or the epidermal growth factor receptor remained factor dependent and did not transform to factor independence after cocultivation with irradiated stromal cell lines. In contrast, cell line bg/bg d64, and each of seven subclonal lines of FDC-P1, including subclones selected for growth in GM-CSF, formed abundant cobblestone island colonies of greater than or equal to 50 cells on irradiated D2XRII stromal cells, produced non-adherent cells over 5-8 weeks, and showed evolution of tumorigenic FI subclonal lines. The data provide evidence for stable biological differences in both the hematopoietic and stromal cell components of the in vitro model of gamma irradiation leukemogenesis.

Abstract
There is evidence for differences in the gamma-irradiation response of different cellular lineages within the bone marrow microenvironment. We previously reported that heterogeneity is demonstrable in the gamma-irradiation response of five clonal stromal cell lines, derived from one human bone marrow specimen, despite morphological, histochemical, cytogenetic, and functional similarity. In the present study we tested whether one stromal cell line could affect the intrinsic radiosensitivity of another. Two clonal stromal cell lines, which display distinct gamma-irradiation responses relative to dose rate were used: KM 101, which shows the same radiosensitivity at a low dose rate of 5 cGy/min (LDR) and a high dose rate of 120 cGy/min (HDR) and KM 104 which shows significant gamma-irradiation resistance at LDR. To facilitate the study of the gamma-irradiation response of each cell line during cocultivation, we derived stable subclones of each, expressing the transfected neomycin resistance (neo-r) gene, which confers resistance to the neomycin analog: G 418. Introduction of the neo-r gene did not alter cell lines radiosensitivity. The results show that cocultivation of stromal cell lines before, during, and after gamma-irradiation induces changes in repair of radiation-induced damage, with a dominant effect of a resistant cell line at LDR. In fact, the radiation survival curves of cocultivated stromal cell lines were always characteristic of KM 104, and a dose rate effect was observed, even when KM 101 was present in large excess. Moreover, our results are consistent with preferential killing of the more radiosensitive stromal cell line: both LDR and HDR Do values of the neo-r KM 101, cocultivated with the parent KM 104 for 24 hr before, and during gamma irradiation were significantly lower compared to the neo-r subclone irradiated alone. The LDR Do value of the neo-r KM 104 cocultivated for 24 hr before, and during gamma irradiation with excess of parent KM 101, was significantly higher, compared to the neo-r cells irradiated alone.

Abstract
To determine the effect of oncogene expression on gamma radiation sensitivity of hematopoietic compared to fibroblastic cells, we selected clonal sublines of an interleukin-3 (IL-3)-dependent hematopoietic progenitor cell line 32D cl 3 and NIH/3T3 embryo fibroblastic cells following transfection with each oncogene linked to the mycophenolic acid resistance gene. Each mycophenolic acid-resistant subclone demonstrated high levels of specific poly(A)+ mRNA for each oncogene. The parent line 32D cl 3 demonstrated similar radiosensitivity at 116 cGy/min (D0 126, n 1.17) compared to 5 cGy/min (D0 123, n 1.65). This pattern was not altered in subclones of 32D cl 3 cells transfected with the epidermal growth factor (EGF) receptor gene and grown in EGF (at 116 cGy/min D0 104, n 0.998, at 5 cGy/min D0 115, n 1.09), or in 32D cl 3 cells expressing the v-sis oncogene (at 116 cGy/min D0 122.4, n 1.79, at 5 cGy/min D0 135, n 1.43). In contrast, expression of the transfected oncogenes v-erb-B, v-abl, or v-src conferred significant radioresistance at 5 cGy/min dose rate (D0 194, n 1.77; D0 165.5, n 1.56; D0 171, n 1.28, respectively). With the exception of v-sis, oncogene expression resulted in nonautocrine factor independence of 32D cl 3 subclones, and production of donor origin tumors in syngeneic new-born or adult mice. Two rare spontaneous factor-independent subclones of 32D cl 3 were also tested. Nonautocrine clone 32D cl 2 demonstrated significantly increased radioresistance at low dose rate (D0 186, n 1.63), while autocrine (IL-3 producing) subclone 32D cl 4 revealed no significant increase in radioresistance at 5 cGy/min. The parent fibroblast cell line NIH/3T3 showed an intrinsic relative radioresistance at low dose rate (at 5 cGy/min D0 157.3, n 1.81, compared to 116 cGy/min D0 134.3, n 1.57). Expression in NIH/3T3 of transfected oncogenes v-abl, v-fms, v-fos, or H-ras increased radioresistance at low dose rate (D0 208.6, n 1.61; D0 206.6, n 1.51; D0 167.5, n 1.85; and D0 206.8, n 1.08, respectively). Thus expression of each of several oncogenes induces resistance to gamma irradiation at 5 cGy/min in hematopoietic and fibroblast cell lines. These data may help explain the clinical recurrence of oncogene-expressing leukemia and lymphoma cells after marrow stem cell ablative doses of low-dose-rate total-body irradiation.

Abstract
In general, collection of serial blood samples from small experimental animals is difficult in terms of sampling site and operation technique. To overcome these problems, a simple reproducible method has been improved by the use of filter papers. Whole blood obtained by venipuncture from the ear vein of guinea-pig was spotted onto a filter paper. Isepamicin in the dried blood spot was extracted with 0.5 M Na2HPO4 buffer by incubation and determined by fluorescence polarization immunoassay. Linearity was established over the range of 5-150 micrograms/ml by using only 100 microliters of whole blood. Consequently its accuracy and precision were good, with mean coefficient of variation of less than 5%. The method described here correlates well with a conventional sampling method and could be used for the pre-clinical study of isepamicin blood levels of individual guinea-pigs. This method is suitable for the simultaneous measurement of aminoglycoside antibiotics or physiological parameters after the administration of aminoglycoside antibiotics for the pharmacokinetics study.

Abstract
The ability of a clonal hematopoiesis-supportive bone-marrow stromal cell line GBlneor to engraft and alter the microenvironment-induced anemia of Sl/Sld mice was studied. Prior to stromal cell transplantation, Sl/Sld mice received 1 Gy total body irradiation (TBI) and 13 Gy to the right hind limb. Two months after intravenous (IV) injection of 5 x 10(5) GBlneor cells, 54.4% +/- 17.0% donor origin (G418r) colony-forming cells were recovered from the right hind limb of Sl/Sld mice. Long-term bone marrow cultures (LTBMCs) established from GBlneor-transplanted mice produced 189.5 CFU-GEMM-forming progenitors/flask over 10 weeks compared with 52.7 +/- 6.2 CFU-GEMM forming progenitors/flask from irradiated nontransplanted Sl/Sld mice. A partial correction of macrocytic anemia was detected 2 months after GBlneor transplantation in splenectomized, irradiated Sl/Sld mice (HgB 7.2 +/- 0.4 g/dL; MCV 68.3 +/- 7.0 fL) compared to splenectomized, irradiated, nontransplanted Sl/Sld mice (HgB 5.5 +/- 1.1 g/dL; MCV 76 +/- 8.5 fL) or control Sl/Sld mice (HgB 5.4 +/- 0.5 g/dL; MCV 82.4 +/- 1.3 fL). Mean RBC volume distribution analysis showed a 2.5-fold increase in percentage of peripheral blood RBCs with MCV less than or equal to 45 fL and confirmed reduction of the MCV in splenectomized-GBlneor-transplanted mice compared to control Sl/Sld mice. A hematopoiesis-suppressive clonal stromal cell line derived from LTBMCs of Sl/Sld mice (Sldneor) engrafted as effectively (43.5% +/- 1.2% G418r CFU-F/limb) as did GBlneor cells (38.3% +/- 0.16% G418r CFU-F/limb) to the irradiated right hind limbs of C57Bl/6 mice. LTBMCs established after 2 or 6 months from Sldneor-transplanted mice showed decreased hematopoiesis (182 +/- 12 [2 months] and 3494.3 +/- 408.1 [6 months] CFU-GEMM forming progenitors/flask over 10 weeks) compared to those established from GBlneor-transplanted mice (5980 +/- 530 [2 months] and 7728 +/- 607, [6 months] CFU-GEMM progenitors forming/flask). Thus, transplantation of clonal bone-marrow stromal cell lines in vivo can stably transfer their physiologic properties to normal or mutant mice.

Abstract
The effects of murine recombinant IL-3 (multi-CSF) and murine recombinant GM-CSF (granulocyte-macrophage colony stimulating factor) on the radiation biology of clonal hematopoietic progenitor cell lines were evaluated. Four clonal cell lines with growth response to either IL-3 or GM-CSF (FDCP-1JL26, and bg/bg d64) or exclusively dependent on IL-3 (32D cl 3 and B6SUtA), were pre-incubated in IL-3, or GM-CSF, for 7 days prior to gamma irradiation, then washed and irradiated at 5 cGy/min, or 116 cGy/min, and transferred to semisolid medium supplemented with either IL-3, or GM-CSF, for assay of 7 day greater than or equal to 50 cell colonies. The cell lines demonstrated similar radiosensitivity and lack of a detectable dose-rate effect when grown in IL-3 (FDCP-1JL26: D0 154, n 1.05 at 5 cGy/min, and D0 138, n 1.16 at 116 cGy/min; bg/bg d64: D0 95.7, n 1.16 at 5 cGy/min, and D0 97.7 n .993 at 116 cGy/min; B6SUtA: D0 101, n 1.29 at 5 cGy/min, D0 100, n 1.27 at 116 cGy/min; and cell line 32D cl 3: D0 123, n 1.65 at 5 cGy/min, and D0 126, n 1.17 at 116 cGy/min). In contrast, FDCP-1JL26 cells demonstrated a significant relative radioresistance at low-dose-rate when grown in recombinant GM-CSF, (D0 217, n 1.27 at 5 cGy/min, D0 138, n 1.34 at 116 cGy/min, p less than .005). The increase in radioresistance of FDCP-1 cells at low-dose-rate was induced either by preincubation in GM-CSF with transfer to IL-3, or by preincubation in IL-3 and transfer to recombinant GM-CSF. Growth factor independent malignant subclones of lines B6SUtA and FDCP-1JL26 demonstrated a significant increase in radioresistance at low-dose-rate (B6SUtA EL4JL: D0 187, n 1.39 at 5 cGy/min, and D0 133, n 1.73 at 116 cGy/min (p. less than .05); and FDCP-1JL26 F7 cl 2: D0 191, n 1.17 at 5 cGy/min, and D0 150, n 1.31 at 116 cGy/min [p less than .05]). Thus, some hematopoietic progenitor cell lines are induced by GM-CSF to grow after irradiation at low-dose-rate similar to the growth of clonal malignant cell lines. The data may have implications for the radiation biology of normal hematopoietic progenitor cells in two circumstances: (a) selective survival of GM-CSF responsive cells after total body irradiation, and (b) selective survival of some hematopoietic progenitors in vivo during clinical recombinant GM-CSF infusion.

Abstract
Two cases of resected esophageal mucoepidermoid carcinoma are described herein. Case 1, a 56-year-old man, had an ulcerous lesion of 6.5 cm in length, in the lower esophagus and a small skin tumor of 0.5 cm in diameter, in the forehead. Pathologic studies of both tumors revealed mucoepidermoid carcinoma. This case was therefore considered to be a primary tumor of the esophagus with skin metastasis. The patient was alive and well when last seen, 15 months after his operation. Case 2, a 66-year-old man, had a long ulcerous lesion of 9.0 cm in length, in the mid-thoracic and lower esophagus. The tumor had invaded the aorta and the membranous portion of the left main bronchus, and therefore complete resection was impossible. The patient died of mediastinal recurrence only 3 months after his operation in spite of postoperative irradiation. A review of the literature showed that this tumor has a much greater incidence of rapid recurrence and distant metastasis, regardless of treatment, than usual squamous cell carcinoma of the esophagus. In order to establish and accurate diagnosis of mucoepidermoid carcinoma, alcian blue and/or mucicarmin staining of the endoscopic biopsy specimen should be performed if the tumor contains both glandular and squamous cell carcinoma.
