objective(s):recent evidence have proposed that tretinoin produced in the gut preferentially promote differentiation of foxp3+treg cells but inhibits th17 lymphocytes, and this may be the main immunomdulatory mechanism of tretinoin  in vivo. this study was done to investigate the effects of tretinoin in outbred white mice after challenge with sheep red blood cells (srbc). materials and methods:...

It has long been appreciated that transferring allogeneic tissues between members of the same species can have complicated effects upon the recipient immune system. Transfusion represents the most common exposure to large quantities of alloantigen, which unlike solid organ transplant, occurs in the absence of pharmacological immunosuppression. Transfused products constitute a complex cellular e...

Filariasis displays a wide range of clinical and pathological manifestations, represented by asymptomatic carriers of microfilaria, symptomatic cases of filariasis with or without circulatory microfilaria and extreme cases of elephantiasis. The immunological status of the host is expected to play an important role in the genesis of the different manifestations. Diagnosis of filariasis is still ...

A case of abdominal Burkitt's lymphoma diagnosed through aspiration cytology is described. This 9-year-old boy presented with abdominal pain and distention for three months accompanied by fever and night sweat during the last month. An abdominal sonography and CT scan showed hepatosplenomegaly and an intrahepatic mass with celiac lymph node enlargement, ascites, and pleural fluid. A peripheral ...

Background: Shark cartilage is one of the complementary medicines for cancer patients that inhibits tumor progression by several mechanisms. There is not sufficient evidence on its effects on human immune system thereby we investigated its modulatory effects on some cellular immune response parameters in breast cancer patients. Material and methods: After preparation of shark cartilage powder ...

A new three-breed cross-hybrid of carp has been obtained in the fish farm «Kirya» Chuvash region (RF). comparative assessment fingerlings showed advantages cross over other crosses grown same (Sursky malokostny and Petrovsky) on a number indicators: weight, body length, indices high-spin, physical development. In youngsters cross, intensity hematopoiesis (erythropoiesis leukopoiesis) is higher ...

Autofocusing is a fundamental procedure towards automated microscopic evaluation of blood smear and pap smear samples for clinical diagnosis. This paper presents comparison results of 16 selected focus algorithms based on 8000 static bright-field images and 1600 dynamic autofocusing trials using 10 blood smear and pap smear samples. Besides static behaviour, dynamic autofocusing performance is ...

OBJECTIVES A comparative study of intradermal smear in the diagnosis of malaria in symptomatic pregnant women. Venous blood served as the control. PATIENTS AND METHODS Fifty consecutive symptomatic pregnant women were recruited. Thick films of both venous and intradermal blood were examined. Questionnaires were used to determine patients' preference for the two techniques. Tests of statistica...
