  • This study was designed to assess the relationship between occupational stress and health status in a study group of 197 workers employed in four newspaper publishing companies, using a self-adminstrative questionnaire. The types of occupation of them were reporters(79), clerical workers(54), and engineers (64). The studies on workers' health have been focused mainly on the physical, chemical, and biological diseases in our country. Therefore, the study of mental health, especially of occupational stress, is to be carried out. I consider stress as a factor having an effect on the health status of the newspaper employees, who have been well known to have high stress due to time pressures. I expect that this research will be helpful not only for understanding of health status by occupation, but also for making clear the issues that have been raised continuously from the previous researches. The results of this study are as follows; 1. The mean values of stress by occupation were statistically significant; the reporters had the highest stress symptom scores, and the engineers had the lowest levels of stress. The mean values of stress symptoms were higher in the workers who had long working hours. 2. The health status by occupation showed significant differences in gastrointestinal systems and in depression. The clerical workers were healthier than the engineers in gastrointestinal systems, and the reporters were more depressed than the engineers in depression. 3. The health status by the general characteristics, there was a statistical significance as for a gender, marital status, and absenteeism in the gastrointestinal systems. The men, the married, and the workers who had not been absent were more healthy. Only absenteeism had an effect on the problems in optical-dermal systems and in oro-fecal systems. Gender, marital status, absenteeism, and working hours were related with health status : the men. the married, the workers who had not been absent, and the workers who had longer working hours were more healthy. In mental stability, gender had a significant effect : the men were more healthy than the women. In general condition, the men, the older, the married, and the workers who had not been absent were more healthy. 4. Stress level had an effect on the health status in the respiratory systems, optical-dermal systems, oro-fecal system, depression, mental stability, general condition, and health condition. The workers who perceived more stress had more problems in their health status. 5. In the results of the multiple regression analyses, age in the respiratory systems, absenteeism in the optical-dermal systems, occupation and absenteeism in the gastrointestinal systems and in the oro-fecal systems, gender in depression and in mental stability, gender, age, absenteeism, and working hours in the general condition, absenteeism in the health condition had an effect on the health status of the workers.

  • Background: Esophagogastroduodenoscopy (EGD) is the standard technique for diagnosis of patients presenting with upper gastrointestinal symptoms. Some reports have shown high prevalence of esophageal cancer in the northern part of Afghanistan. The aim of this study was to investigate epidemiological profile of esophageal cancer among patients in this region. Materials and Methods: We identified 364 consecutive patients that received EGD examinations to examine upper gastrointestinal tract at the endoscopy unit of Balkh regional Hospital from March 2012 to March 2013. The case subjects included both in-patients and out-patients aged 16 years or more. We evaluated the results retrospectively. Results: The cases consisted of 184 (51%) males and 180 (49%) females. The mean age was $47.3{\pm}17.8$ and the age range 17-88 years. Ninety two cases had esophageal cancer, out of which 58 (63.0%) were male. The mean age at time of diagnosis was $57.8{\pm}13.2years$. Uzbek-Turkmen peoples were more common among patients with esophageal cancer (52.2%). Dysphagia was the most frequent symptom among patients with esophageal cancer at the time of presentation, seen in 77 (84.8%) of cases. Conclusions: Our results showed high incidence of esophageal cancer in the northern part of Afghanistan, especially in the Uzbek-Turkmen ethnic group.

  • This study examined the laxative effects of mulberry leaf extract (MLE) fermented by lactic acid bacteria (LAB), which contains high levels of polyphenolic and flavonoid compounds, against loperamide-induced constipation in rats. Sprague-Dawley rats were divided into a normal group (N) and three experimental groups; loperamide treated group (C), loperamide and LAB-fermented MLE 300 mg/kg treated group (MLEL), and loperamide and LAB-fermented MLE 600 mg/kg treated group (MLEH). After 33 d, fecal pellet amount, fecal weight, water content of fecal, gastrointestinal transit time and length, and serum lipid profiles were measured. Constipation was induced via subcutaneous injection of loperamide (2.0 mg/kg b. w., twice a day) for the final 5 d of the experiment. After loperamide administration, the LAB-fermented MLE groups showed a significantly increase in the fecal pellets number, wet weight, and water content in rats compared with the C group. Moreover, increases in the intestinal length and viable Lactobacillus numbers in the feces were observed in the LAB-fermented MLE groups. The intestinal transit time was shorter in the LAB-fermented MLE groups than in the C group. In addition, the LAB-fermented MLE groups showed a significant decrease in triglyceride and total cholesterol levels and an increase in HDL-cholesterol level. These results indicated that oral administration of LAB-fermented MLE shows laxative effect in loperamide-induced constipated rats.

  • Gastric lavage is one of gastrointestinal decontamination methods which have been controversial in the clinical toxicology field for a long time. Expert groups of American and European clinical toxicologists have published the position papers regarding gastric lavage three times since 1997. They recommended that gastric lavage should not be used as a routine procedure in the management of acute intoxication, because they thought that there is no certain evidence of improving clinical outcome by its use. However, the studies they reviewed were not well-controlled randomized trials, which cannot be conducted in the clinical toxicology field due to variability of patients and ethical problems. Therefore, the results from these studies should be interpreted with caution. They also insisted that gastric lavage can be undertaken within 60 minutes of ingestion. The limitation of one hour after ingestion is too arbitrary and may cause a lot of misunderstanding. Formation of pharmacobezoar or gastric hypomotility after ingestion may significantly delay the gastric emptying time so that gastric lavage can be useful even after several hours or more in case of highly toxic substances or severe intoxication. Furthermore, as there are a number of serious intoxication by toxic pesticides with large amount in suicidal attempts in Korea, it seems that gastric lavage may be used more frequently in Korea than in Western countries. When deciding whether or not to use gastric lavage, all the indications, contraindications, and possible adverse effects should be taken into account on the basis of risk-benefit analysis. If the procedure is decided to be done, it should only be performed by well-trained experts.

  • Purpose: To determine clinically useful biochemical markers reflecting disease activity and/or gastrointestinal (GI) tract involvement in Henoch-$Sch{\ddot{o}}nlein$ purpura (HSP). Methods: A total of 185 children with HSP and 130 controls were included. Laboratory data indicating inflammation, standard coagulation, and activated coagulation were analyzed for the HSP patients, including measurements of the hemoglobin level, white blood cell (WBC) count, absolute neutrophil count (ANC), platelet count, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) level, prothrombin time, activated partial thromboplastin time, and fibrinogen, D-dimer, and fibrin degradation product (FDP) levels. The clinical scores of the skin, joints, abdomen, and kidneys were assessed during the acute and convalescence phases of HSP. Results: The WBC count, ANC, ESR, and CRP, fibrinogen, D-dimer, and FDP levels were significantly higher in the acute phase compared with the convalescent phase of HSP (p<0.05). The total clinical scores were more strongly correlated with the D-dimer (r=0.371, p<0.001) and FDP (r=0.369, p<0.001) levels than with inflammatory markers, such as the WBC count (r=0.241, p=0.001), ANC (r=0.261, p<0.001), and CRP (r=0.260, p<0.001) levels. The patients with GI symptoms had significantly higher ANC (median [interquartile range], 7,138.0 [4,446.4-9,470.0] vs. 5,534.1 [3,263.0-8,153.5], p<0.05) and CRP (0.49 [0.15-1.38] vs. 0.23 [0.01-0.67], p<0.05), D-dimer (2.63 [1.20-4.09] vs. 1.75 [0.62-3.39]), and FDP (7.10 [0.01-13.65] vs. 0.10 [0.01-7.90], p<0.05) levels than those without GI symptoms. Conclusion: D-dimer and FDPs are more strongly associated with disease activity and more consistently reflect GI involvement than inflammatory markers during the acute phase of HSP.

  • The purpose of this study was to investigate the effects of dietary xylooligosaccharide on lipid levels of serum in rats fed high cholesterol diet. Male Sprage-Dawley rats weiging 100$\pm$10g were randomly assigned to groups of two normal(N, N+10X) and four high cholesterol diets which contained 1%(w/w) cholesterol. High cholesterol diet groups were classified to xylooligosaccharide free diet (C group), 5% xylooligosaccharide diet(C+5X group), 10% xylooligosaccharide diet(C+10X group) and 15% xylooligosaccharide diet(C+15X group) according to the level of dietary xylooligosaccharide supplementation. These experimental diets were fed ad libidum for 4 weeks. The weight gain of high cholesterol diet group were significantly increased more than that of normal group, but those of 10% and 15% dietary xylooligosaccharide groups were significantly decreased more than that of high cholesterol diet(C)group. The higher content of xylooligosaccharide, the more food intake was increased. The food efficiencies of 10%, 15% cholesterol diet groups were lower than that of high cholesterol diet(C)group. The levels of serum triglyceride(TG) and total cholestoral were significantly high in cholesterol diet groups compared with normal diet group but were decreased in groups fed 5% and 10% dietary xylooligosaccharide. Especially, the lowest level showed in group fed high cholesterol diet containing 10% xylooligosacchride. High cholesterol diet group containing 10% xylooligosaccharide increased HDL-cholesterol level and then decreased LDL-cholesterol level and atherogenic index compared with other groups. The level of TBARS(thiobarbituric acid reactive substances) in serum was decreased in rat group fed xylooligosaccharide in high cholesterol diet. The higher content of xylooligosacchride, the more gastrointestinal transit time was decreased. The results indicate that dietary xylooligosaccharide can improve status of TG and total cholesterol and repress lipid peroxidation in serum lipid at hypercholesterolemia induced by high cholesterol diet.

  • The purpose of this research was to investigate the efficacy of Goiwhasan extract powder on the gastric injuries, antiulcer, gastrointestinal tract and blood hemostasis. Animals were used through this studies mice and rats. All animals were divided into 3 groups, contol group(no treatment), sample Ⅰ group(375mg/kg administration), sample Ⅱ group(750mg/kg administration). The gastric injuries and ulcer have been made by using pyloric ligation, indomethacin, HCI-ethanol, acetic acid and then The histological observation was followed. In the gastrointestinal tract, gastric juice secretion, gastric acidity, pepsin output, blood gastrin and secretin level, transport potentials in the small and large intestine were checked. And studies on blood hemostasis were performed on normal hemostatic activities and plasma prothrombin time, plasma recalcification time, plasma fibrinogen levels in the hypoprothrombinemic mice induced by warfarin. The results were as follows: 1. The antigastric ulcer effects on the pyloric ligation, indomethacin, HCl-ethanol, acetic acid induced gastric injuries were shown in Sample Ⅱ group(p<0.05). 2. Through the morphologic examination on the acetic acid induced ulcer, Sample Ⅰ group showed mild regeneration of epithelium and slight decrease of periulcer edema then that of Control group, while Sample Ⅱ group showed more retraction of round ulcer site, remarkable loss of swelling and edema then that of Control group, and revealing the regenerated epithelium in the surrounding ulcer site. Thus it was noted that both Sample groups have antigastriculcer effects on the experimentally induced gastric ulcer. 3. The inhibitory effects on gastric juice were noted in both Sample Ⅰ group(p<0.05) and Sample Ⅱ group(p<0.01). However, only Sample Ⅱ group showed the inhibitory effects on total acidity and pepsin output(p<0.05). 4. The significant inhibition of blood gastrin level showed at 30 min.(P<0.05) and 90 min.(P<0.05) after starting medication in only Sample Ⅱ group, but significance of blood secretin level in both groups was not recognized. 5. Any significant changes in barium sulfate transport in the small intestine of mice was not recognized in both groups, but the significantly inhibitory effect in large intestine was recognized in both Sample Ⅰ group(p<0.05) and Sample Ⅱ group(p<0.001). 6. In hemostatic effect on both normal mice and hypoprothrombinemic mice induced by warfarin, the significantly shortening effect on coagulation time was seen in only Sample Ⅱ group(p<0.01). 7. On plasma prothrombin time in hypoprothrombinemic rat induced by warfarin, Sample Ⅱ group have shortened the prothrombin time significantly(p<0.001). 8. On plasma reclcification time in hypoprothrombinemic rat induced by warfarin, the recalcification time have been shortened significantly in both Sample Ⅰ group(p<0.05) and Sample Ⅱ group(p<0.01). 9. On plasma fibrinogen levels in hypoprothrombinemic rat induced by warfarin, the fibrinogen contents in Sample Ⅱ have been decreased significantly(p<0.01). Overall the above results suggest that Goiwhasan has an therapeutic efficacy on antigastric ulcer and blood hemostasis. Further studies would be needed on the interaction of its herbal medicine and its mechanism in the future.

  • Image-guided radiation therapy (IGRT) is a process of incorporating imaging techniques such as computed tomography (CT), magnetic resonance imaging (MRI), Positron emission tomography (PET), and ultrasound (US) during radiation therapy (RT) to improve treatment accuracy. It allows real-time or near real-time visualization of anatomical information to ensure that the target is in its position as planned. In addition, changes in tumor volume and location due to organ motion during treatment can be also compensated. IGRT has been gaining popularity and acceptance rapidly in RT over the past 10 years, and many published data have been reported on prostate, bladder, head and neck, and gastrointestinal cancers. However, the role of IGRT in lymphoma management is not well defined as there are only very limited published data currently available. The scope of this paper is to review the current use of IGRT in the management of lymphoma. The technical and clinical aspects of IGRT, lymphoma imaging studies, the current role of IGRT in lymphoma management and future directions will be discussed.
