Non-Hodgkin's lymphoma is the third most common cancers in children. In the present study to determine pathological and clinical features of this cancer, we reviewed records of 84 Cases of Non-Hodgkin's lymphoma who were admitted to Aliasghar and Bahrami children hospitals from 1989 to 1996. 59% of cases had small noncleaved cell (SNCC) subtype of disease. 15% were lymphoblastic and 5% diffuse large cell subtype. The most prevalent primary sites were abdomen and lymph nodes. The most prevalent symptoms were abdominal mass (34%), abdominal pain(37%) and cervical lymphadenopathy (26%). Over half of our patients were small noncleaved cell subtype, and further studies should be done to find out reasons for this unusual finding.

Sarcoidosis is a chronic multisystem disorder of unknown etiology. All parts of the body can be affected but the organ most frequently affected is the lung. Otolaryngologic manifestations occur in 20% to 40% of cases of Sarcoidosis and the spectrum of lesions that may come under the purview of Otolaryngologist is broad.In this case report a patient is presented with large cervical lymphadenopatty and without other manifestation of disorder.

Tuberculosis is the main infectious cause of mortality and morbidity in the world. One of the basic methods of the diagnosis of T.B is evaluation of radiological manifestations of the patients. Considering that Hormozgan is among the areas with high prevalence of T.B, by evaluation of radiological manifestations of patients with pulmonary T.B, its prevalence, with respect to some factors such as: age, sex, sputum examination, association with AIDS and prevalence in certain groups such as prisoners was investigated. On the other hand, this study was aimed to help evaluation and earlier diagnosis of the patients. First chest X-Ray of a total of 262 new cases of pulmonary T.B. who referred to Bandar Abbas health center was reviewed. Results showed that 74.8% of the patients were male andJ25.3% female. 12 patients (4.58%) were in the pediatric age group. 5 patients (1.9%) had military T.JB. 2 cases (0.7%) were accompanied with AIDS. 57 patients (22%) were prisoners and 172 patients (65.7 %) had positive AFB. Prevalence of radiological manifestations in these 262 patients were: Infiltration 86.25 %, cavity 49.62 %, pleural thickening 44.27%, calcification 35.11 %, fibrosis 31.24%, atelectasis 19.8%, lymphadenopathy 18.32%, hydro thorax 13.74%, bronchiectasis 2.24% and tuberculoma 1.9%.    

Background and purpose: Because of the widespread presence of atropine and scopolamine as two major alkaloids in Datura stramonium plant, this study was conducted with following objective in mind:1. Isolation of the major alkaloids in Datura stramonium, grown in the city of Ahwaz, for the evaluation of the effects of climatic changes on the types and quality of these alkaloids.2. Identification and characterization of their structures by spectroscopic methods of IR, UN-VIS; MASS, 13 CNMR and HNMR.Materials and Methods: Atropine and scopolamine alkaloids were isolated by extraction of Datura stramonium in alcohol-Acid sotutions and then purification of atropine and scopolamine was done by thin layer chromatography (TLC) method.Results: Because of the complexity of the chemical structures of these alkaloids, their structures were determined and confirmed on the basis of their IR, NMR, UN-VIS and MASS Spectra.Conclusion: The major alkaloids in Datura stramonium plant are Atropine and Scopolamine.Environmental factors such as climatic changes and the cultivation place did not have any significant effect on the quality and quantity of these alkaloids.

Background and Objectives: Radiological findings of the adulthood tuberculosis regarding mediastinal and hilar lymphadenopathy versus primary tuberculosis of the childhood are known to be uncommon. However, according to our investigations on 10 patients during a period of 12 years, its probability cannot be denied.Methodology: From 1983 to 1997 ten patients were assessed by collecting the required data from their medical records and the outcome of antituberculous treatment.Results: Mean age of the enrolled patients in this study was 31 years. They were referred with different clinical complaints and showed mediastinal lymphadenopathy on the chest x-rays. Hilar lymphadenopathy were noticed less commonly.Conclusion: Hilar and mediastinal lymphadenopathy are fairly common findings of the childhood tuberculosis, but in adults, although being very rare, does not occur unexpectedly, as witnessed by the recent investigations in United States and Canada for the time being.

Background and purpose: Anthrax is a zoon otic disease common between animals and man which is caused by a gram positive spore forming bacillus, known as Bacillus Anthracis.This disease is still one of the causes of health problems in developing countries.Chahar Mahal Bakhtyari state is one of the agricultural and animal breeding centers of Iran and annually many of the human and animals die of this disease.Materials and Methods: A study done on so Cutaneous anthrax patients at infectious disease ward of Ayatollah Kashani hospital in shahre Kord.Results: The findings were as follows:-It was more prevalent in the age groups of 11-20 years old, and there were more cases in males than females.-Most of the patients were infected in summer season, and 96% of them were from rural areas. 32% of cases had history of contact with animals and 12% insect bites -The most infected organs were face, hands and arms. 100% of cases had non pitting oedema, and 80% had necrotic lesions with surrounding erythema.Fever, headache and regional lymphadenopathy was observed in 78% , 64% and 42% respectively.-Helpful laboratory diagnostic criterias were ESR, Leucocytosis and positive CRP, but final confirmation is based on preperation of an smear from the exudates and culture on mediums.-All the patients were treated with penicillin and 92% of the patients were relieved of fever three days after initiation of treatment. In this study the mortality rate was zero percent and the most common side effect was the secondary infection at the site of the wound.Conclusion: It is concluded that in endemic areas, all wound cases with nonpitting oedema with or without necrotic lesions should be considered for anthrax, and more knowledge about the disease in the developing countries and development of medical researches specially for the purpose of prevention would help in decline of the number of infected cases.
